After Ningbo, Kunming, Maoming and other places, another petrochemical project was opposed by "public opinion" and faced with dismounting.

On May 10, 2016, in the turbulent opposition of citizens, the Longkou Municipal Government of Shandong Province stopped the environmental impact assessment of a large petrochemical industrial park project jointly invested with Singapore. The Public Security Bureau of Longkou City, Shandong Province issued notices on May 10th and 11th, and the environmental assessment and demonstration work of Yulong Petrochemical Industrial Base stopped. Please ask the masses not to continue gathering, not to believe or spread rumors. Police said on the 11th that some people still instigate, plan, organize and participate in illegal assemblies, processions and demonstrations.

On May 4th, according to the relevant provisions of the national environmental protection laws and regulations, Longkou Environmental Protection Bureau made the first EIA announcement on the overall development plan of Longkou Yulong Petrochemical Industrial Base. This EIA publicity is the legal pre-stage of the EIA approval of the project planning, and its purpose is to solicit opinions and suggestions from the general public.

According to the public notice, Yulong Petrochemical Industrial Base is located in the west of Longkou City, with a total planned area of about 50.4 square kilometers. It is planned to build 40 million tons of oil refining, 2.2 million tons of ethylene, 6 million tons of aromatic hydrocarbons and its middle and lower reaches industrial chain projects, which will be implemented in stages.

At present, in the process of publicity, some Longkou citizens have doubts about the safety and environmental protection of the overall development plan of the base, and they are worried about the potential environmental impact of this petrochemical project on human health and reflect it through various channels.

Yulong Petrochemical Industrial Base is a cooperative project between Nanshan Group in China and Jurong International in Singapore. In June 2014, the two sides signed a memorandum of cooperation, and planned to learn from Singapore’s experience in establishing a petrochemical industrial park on Jurong Island, which was artificially reclaimed from the sea, to build a petrochemical industrial base in Bohai Bay, China. Song Jianbo, chairman of Nanshan Group, once told the media that the construction of Yulong Island should be in line with international first-class standards.

Jurong Island in Singapore is the third largest oil refining center in the world, located off the southwest coast of Singapore, only 5 kilometers away from the main city of Singapore. The distance between ExxonMobil’s 370,000-ton/year PX plant and residential areas on the island is less than 1 kilometer. Because it has never had a major pollution accident, it is called a great example of "chemical industry can coexist with blue sky and blue sea"

On the morning of May 10, 2016, some Longkou citizens gathered in front of the municipal government, calling on the government to stop launching this project and return the citizens to "blue sea and blue sky". "The government’s lack of public information about the project makes it impossible for us to have a deeper understanding of the project itself. But what we clearly know is that in recent ten years, the environment in Longkou has gone from bad to worse, and it is almost unsuitable for survival. " In a proposal, Longkou citizens wrote.

Faced with pressure, in the afternoon, the Longkou Municipal Government issued a reply to the environmental impact assessment publicity of Longkou Yulong Petrochemical Industrial Base Project in official website, saying, "According to the opinions and suggestions of the masses during the publicity period, the municipal government decided to stop the environmental assessment and demonstration work."

The Longkou Municipal Government also stressed that the petrochemical project is now in the stage of planning and demonstration. The purpose of the previous EIA publicity was to solicit opinions and suggestions from the general public on the plan, but no final decision was made.

"In the near future, we will carefully analyze and sort out the opinions and suggestions collected from different channels and truthfully feedback them to the report preparation unit. In response to the environmental assessment of the overall development plan, we will review and check in strict accordance with relevant national laws and regulations, and earnestly perform our environmental protection duties. If the environmental assessment link fails to meet the requirements, we will resolutely not promote it. " The Longkou Municipal Government wrote in another announcement.

On the same day, Longkou Public Security Bureau also issued a notice on prohibiting illegal assembly, procession and demonstration: On May 10th, Longkou Municipal People’s Government and Longkou Public Security Bureau successively issued an announcement and a notice on the issue of Yulong Petrochemical Industrial Base. But up to now, some people still incite, plan, organize and participate in illegal assemblies, processions and demonstrations.

According to the notice, on the morning of May 10th, the Longkou Municipal People’s Government has studied and decided and issued an announcement, and the environmental assessment and demonstration work of Yulong Petrochemical Industrial Base has stopped. In order to ensure the safety of life and property of the country and the people and maintain the normal order of work, production and life, the masses are requested not to continue to gather, not to believe in rumors and not to spread rumors. If you don’t listen to advice, continue to illegally organize, participate in or incite organizations, participate in assemblies, processions and demonstrations through mobile phones, the Internet, etc., the public security organs will deal with them in strict accordance with the provisions of the Law of the People’s Republic of China on Assemblies, Processions and Demonstrations and the Criminal Law of People’s Republic of China (PRC), and severely crack down on illegal and criminal acts. At the same time, please ask the broad masses of people to consciously resist illegal assemblies, processions, demonstrations and other acts, take the initiative to report illegal and criminal activities to the public security organs, and jointly safeguard the harmony and stability of Longkou society.

On May 11th, Longkou Public Security Bureau issued a second notice with severe wording.

According to the law, the environmental impact assessment of new projects must be completed before the project is started. The construction and development activities that may affect the environment should be investigated, predicted and evaluated in advance, and a report on the environmental impact and prevention plan should be put forward. The construction can only be carried out after the approval of the competent department. The municipal government’s call to stop the EIA work means that this petrochemical project will also stagnate in theory.

According to a Longkou citizen interviewed by Caixin reporter, "At present, Longkou has been polluted by titanium dioxide and oil shale, so it is uninhabitable. This street trip is an outbreak of contradictions to a certain extent." She said that in the case that the old environmental problems have not been properly solved, it is difficult for Longkou citizens to tolerate a petrochemical project that may bring greater harm and threat. She believes that in recent years, there are more and more people suffering from leukemia among Longkou citizens, and some communities have become cancer communities, which are closely related to environmental pollution.

The announcement of the Longkou Municipal Government also promised to the public that the environmental problems in Longkou City will be intensified. "If the production is stopped, the ban will be banned."

Expert: Game between Petrochemical Industry and Real Estate Industry

Qu Ruijing, a senior expert of China Circular Economy Association and a senior researcher in the chemical industry, believes that the site selection and planned equipment of the project in Longkou Petrochemical Industrial Park have the conditions to minimize the impact of the people, but it is debatable that the local government hastily stopped the EIA demonstration work in the face of public opposition. The domestic demand for petrochemical industry is still high. Qu Ruijing introduced that in 2015, China’s imports of PX products reached one-fifth of the global production capacity, taking PX-p-xylene, which once caused strong neighborhood feelings, as an example, and the domestic production capacity of PX was seriously insufficient.

"Longkou’s environmental problems are problems left over from history and have little to do with the current project establishment. However, the petrochemical projects in our country have now entered a misunderstanding, not only because of people’s worries about environmental hazards, but also because of the game between the petrochemical industry and the real estate industry. " Qu Ruijing told reporters.

　　Author: Yu Hua (media commentator)

　　On August 17th, General Secretary of the Supreme Leader presided over the Standing Committee of the Political Bureau of the Communist Party of China Central Committee meeting of the CPC and delivered an important speech. The meeting conducted research and deployment on flood control, flood relief and post-disaster recovery and reconstruction, emphasizing that "all relevant regions, departments and units should always tighten the string of flood control and disaster relief, and always put the safety of people’s lives and property first, with ‘ Always uneasy ’ A sense of responsibility, be careful to do a good job in flood control, flood control and disaster relief. "

　　"Seven falls and eight rises" is the key period of flood control in China. Recently, disasters such as rainstorms, floods and typhoons are still high in many places across the country, and there are still risks of floods in some river basins. See the responsibility at the critical moment. Under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, Party committees, governments and relevant departments at all levels have made every effort to fight the tough battles of flood control and emergency rescue and the protection of the affected people, and the struggle for flood control, flood control and disaster relief has achieved major milestones.

　　Based on "people", all measures fully consider the "people" factor, and pay close attention to all the work of flood control and disaster prevention. We must always insist that the interests of the people are above everything else, always think about problems and make decisions from the standpoint of the people, and fight a prepared and sure initiative. On the one hand, highlight the key points of defense, continue to carry out investigation and rectification of hidden dangers, especially focus on the key parts and weak links of defense, do a good job in avoiding risks, and minimize casualties and disaster losses. At the same time, adhere to the "two-handed grasp" and "two-handed hard" of flood control and disaster relief. Properly resettle the lives of the affected people, increase the investment of disaster relief funds and materials, ensure the service of centralized resettlement sites in detail, effectively protect the basic living needs of the people such as food, accommodation and medical treatment, sincerely care for and properly resettle the affected people, and restore production and living order as soon as possible.

　　Give priority to "defense", play a good first move and play an active battle. More preparations for flood control, more careful investigation of potential safety hazards, and better security for the masses. Further improve the ability of "prevention", do a good job of "preparation", and constantly strengthen the risk awareness with the mentality of "I would rather prevent ten and nine empty, but I can’t fail to prevent it in case" and "I would rather prepare instead of using it, and I can’t use it without preparation", scientifically predict all kinds of disaster risks that may occur during the flood season, and always be on high alert. At the same time, only by doing all kinds of plans well and doing all the basic work well can we grasp the initiative and win the initiative. By strengthening the real-time monitoring of rain, water and mountain flood disaster risks, strengthening emergency treatment and making emergency plans, we can ensure that materials, personnel and measures for flood control and flood fighting are fully prepared, and we can be more sensitive to flood situations, win the opportunity for flood control and disaster relief, and truly realize early detection, early disposal and early resolution of potential risks.

　　Flood control work is related to the safety of people’s lives, and there is no room for paralysis and slack. Flood not only tests the disaster prevention and relief system and emergency response ability of all levels and departments, but also tests the feelings and responsibilities of party member cadres at all levels for the people. Party organizations at all levels should give full play to their strong leadership role, cadres at all levels should give full play to their exemplary role, and the vast number of party member should give full play to their vanguard and exemplary role, charging ahead, taking the lead, taking the initiative and taking the lead, maintaining the sense of responsibility of "always worrying about it" and the sense of urgency that every second counts, and earnestly guarding the soil with responsibility, responsibility and responsibility. Early warning before flood, investigation of potential risks, command and dispatch during flood control, transfer and resettlement of affected people, etc., all links and tasks need to be compacted. It is believed that the iron wall of flood control can be built by compacting the responsibility of flood control and disaster prevention in the feelings of planting for the people and grasping the various flood control and disaster relief measures.

Recently, the North China Environmental Protection Supervision Center of the Ministry of Environmental Protection, together with the Environmental Protection Department of Henan Province, gave feedback to the Xinxiang Municipal Government on the comprehensive supervision of atmospheric and water environmental management in Xinxiang City. The main leaders and in-charge leaders of Xinxiang Municipal Government, the main leaders of counties (cities, districts) governments and relevant departments and relevant personnel attended the feedback meeting. In order to implement the new Environmental Protection Law, promote the implementation of the Air Prevention Action Plan and the Water Pollution Prevention Action Plan, and strengthen the government’s environmental responsibility, according to the work deployment, the North China Environmental Protection Supervision Center and the Henan Provincial Environmental Protection Department conducted a comprehensive supervision on the air and water environment management in Xinxiang City from March to April this year. Adhering to the problem orientation, the inspection team made a comprehensive analysis of Xinxiang’s environmental protection, especially the prevention and control of air and water pollution, through unannounced visits, thorough inspection and verification, on-site inspection, visiting departments, consulting materials and accepting reports.

The inspector believes that in recent years, Xinxiang Municipal Party Committee and Municipal Government have paid equal attention to development and protection, constantly strengthened the working mechanism of environmental protection, and improved the assessment system of environmental protection targets. After years of efforts, the city’s industrial structure has been optimized, and the environmental protection management of key industries, the demolition and reform of coal-fired boilers, and the elimination of yellow-label vehicles have been steadily promoted, and positive progress has been made in urban environmental construction, upgrading of traditional industries, and creation of ecological demonstration. Since the implementation of the new environmental protection law, the enforcement of environmental supervision has obviously increased.

The inspector pointed out that although Xinxiang has made positive progress in environmental protection, the problems are still outstanding and the situation is not optimistic from the current situation of environmental quality in the city.

Environmental problems are prominent, and pressure transmission is weak.

First, the quality of the city’s air and water environment is not optimistic. In 2015, the annual average concentration of PM10 in Xinxiang was 158 μ g/m.

^three

The average concentration of PM2.5 is 94 μ g/m.

^three

, the number of days to reach the standard is 147 days, and the rate of reaching the standard is 40.3%.The annual average increase of PM10 and PM2.5 is the first in 18 cities in the province.In the past two years, the annual work objectives and tasks set by the Blue Sky Project have not been completed, and in 2015, the atmospheric environmental indicators did not fall but rose, showing a deteriorating trend. In 2015,The compliance rate of the target section of surface water environmental quality responsibility in the city is 60.4%., did not reach the provincial target of not less than 80%. The compliance rate of the assessment section in Haihe River Basin is even lower. The annual compliance rate of the Xiamaying section of the communist canal Weihui is only 33.3%, and the compliance rate of the Weihe Weihui Huangfu section is only 8.3%.

Second, departmental linkage and pressure transmission are weak.Xinxiang’s environmental protection work mechanism is imperfect, the responsibilities of departments are unclear, the pressure transmission is not in place, and the assessment accountability is not implemented.The city’s loose burning coal base is unclear, the pollution situation is unknown, and there is a lack of basic control measures; The investigation of black and odorous water bodies is not in place, and effective pollution interception and control measures have not been formulated and taken; Groundwater quality and water pollution control also have problems such as unclear departmental responsibilities and poor coordination and promotion; The pollution control of livestock and poultry breeding, the ban on burning straw and garbage, etc. all exist the phenomenon of buck passing between departments. Grass-roots governments have not obviously felt the pressure, and some grass-roots governments and relevant departments have copied the plans of their superiors when formulating the "three major projects".

Third, the environmental problems of industries and industrial clusters are outstanding. The industries with high energy consumption and high pollution in Xinxiang account for a large proportion, and the layout is not reasonable. The industries with high energy consumption and high pollution, such as cement, chemical industry, papermaking and pharmacy, are concentrated, and their production capacity and output rank among the top in the province. The environmental problems in industrial clusters are outstanding. Among the 12 provincial-level industrial clusters in the city, 6 industrial clusters such as fengqiu county and Yuanyang County failed to pass the planning environmental assessment, 9 industrial clusters such as Xindong and Huixian County failed to achieve central heating, and the sewage treatment plants in two industrial clusters failed to be built as required. Although the industrial wastewater in three industrial clusters entered the sewage treatment plants for treatment, the sewage treatment plants exceeded the standard for a long time.

Fourth, the key work of air pollution prevention and control has not been implemented enough. The total coal consumption is not well controlled, and the consumption is still increasing year by year. In 2015, coal accounted for 77.9% of the total energy consumption in the city. The coal quality is not optimistic. In December 2015, the unqualified rate of total sulfur and volatile matter in commercial coal (briquette) was 30%, and the unqualified rate of total sulfur in coal-fired enterprises was 19%. The control of dust pollution is weak, and most construction sites have not implemented the "six 100%" requirements; The problem of road dust is prominent, and there are many large-scale heavy-duty vehicles pulling sand and gravel in the urban ring road and National Highway 107, and most of them have not taken dust prevention measures such as covering; There is a serious shortage of mechanical scanning vehicles in urban areas, and the mechanical scanning rate of urban main roads is far below the 80% target set by the implementation plan of Xinxiang Blue Sky Project. There is a risk of rebound in straw burning, and the control of waste incineration in the city is not strict; There are many problems in oil quality and oil and gas recovery. Ten private gas stations sampled and tested gasoline, and many found unqualified oil products.

Fifth, water pollution control has a long way to go. Xinxiang’s industries such as medicine, paper-making, chemical fiber, chemical industry, wine and beverage, food processing and textile account for about 80% of the city’s industrial water pollution emissions every year. The problem of direct sewage discharge is still common. The coverage rate of sewage pipe network in the city is about 70%, and about 150,000 tons of industrial wastewater and domestic sewage are directly discharged into rivers every day. Xinxiang City has built 14 sewage treatment plants, and 4 of them have not been put into operation. Among the 10 sewage treatment plants in operation, two sewage treatment plants have insufficient water collection and cannot operate normally; The two sewage treatment plants have been overloaded for a long time, and there are often problems of excessive discharge and sewage overflow; The two sewage treatment plants discharge about 170,000 tons of wastewater exceeding the standard every day because they accept high-concentration industrial wastewater. The environmental problems of livestock and poultry breeding are not optimistic, and more than 300 large-scale farms (communities) have no pollution prevention facilities; However, non-large-scale livestock and poultry farmers generally have not built supporting pollution prevention facilities, and the pollution situation is outstanding.

Sixth, the construction of environmental infrastructure is seriously lagging behind. The construction of sewage treatment planning projects is slow. Of the 18 projects required to be completed and put into operation by the end of 2015 in Henan Province, 12 projects have not been completed. The urban central heating rate is low. According to the calculation, the urban central heating rate is less than 20%, which brings great challenges to air pollution control in winter. The operation and management of domestic waste landfill is not standardized. There are some problems in 8 domestic waste landfills in Xinxiang city, such as irregular landfill, abnormal operation of leachate treatment facilities, and failure to timely check and accept.

Seventh, some enterprises have repeatedly banned environmental violations and violations. There is fraud in boiler modification of Huaxing Pharmaceutical Factory in Xinxiang, Henan Province; The supporting desulfurization facilities of No.1 boiler in the enterprise are not operating normally; No.4 75t/h boiler has no environmental protection procedures, and the desulfurization and denitrification facilities operate illegally. Henan Li Gu Special Cement Co., Ltd. resumed production without authorization after being punished by Henan Provincial Environmental Protection Department and stopped production for rectification, and caused pollution to the surrounding atmospheric environment. The inspection also found that Xinxiang Jujing Chemical Co., Ltd., Huojia Dongzhangju New Wall Building Materials Factory, Xinxiang Huazhong Cement Co., Ltd., Yanjin Satellite Environmental Protection New Building Materials Co., Ltd., Xinxiang Xintailong Wood Industry Co., Ltd. and Huarui Hi-Tech Co., Ltd. have problems such as abnormal operation of pollution prevention facilities and illegal production.

Strengthen pressure transmission and strengthen problem rectification.

In response to the above problems, the inspection team requested that Xinxiang City should conscientiously do a good job in rectifying the feedback from comprehensive inspections. The rectification plan should be submitted to the Ministry of Environmental Protection and the Henan Provincial Government within 20 working days, and the rectification plan should be "checked, assessed and accountable". In promoting the rectification work, we should further unify our thinking, strengthen pressure transmission, strictly implement the requirements of the Environmental Protection Law and the Notice of the General Office of the State Council on Strengthening Environmental Supervision and Law Enforcement, and resolutely promote the new normal of environmental law-abiding.

At the feedback meeting, the Environmental Protection Department of Henan Province stressed: First, it is necessary to recognize the current grim situation, earnestly enhance the sense of urgency and responsibility in environmental protection work, and deeply understand the decision-making arrangements of the CPC Central Committee and the State Council on ecological civilization construction and the firm determination to strengthen environmental protection work. Xinxiang city should draw inferences from others, comprehensively sort out the outstanding problems that restrict the improvement of environmental quality, firmly seize the major opportunities currently facing, and make overall plans to promote a win-win situation for environmental protection and economy. Second, it is necessary to highlight key areas, pay close attention to the rectification and implementation of outstanding environmental problems, keep a close eye on the objectives, implement responsibilities, ensure the completion of the objectives and tasks assigned by Henan Province’s "Blue Sky Project Implementation Plan", do a good job in comprehensively improving the water environment, strengthen the centralized rectification of industrial clusters and industrial parks, severely crack down on outstanding environmental violations, and strengthen the construction of environmental monitoring networks. Third, it is necessary to strengthen the "four responsibilities", build a general pattern of environmental protection under the leadership of party committees, government responsibility, departmental cooperation and social co-governance, and strengthen the leadership responsibilities of party committees and governments, which should be strictly implemented in accordance with the clear requirements of the central government on environmental protection "Party and government share the same responsibility and one post and two responsibilities"; Clarify the "three management and three necessities" responsibilities of relevant departments, strictly enforce the unified supervision responsibility of environmental protection, and implement the responsibility of pollutant discharge units to abide by the law.

Finally, Wang Dengxi, acting mayor of Xinxiang Municipal People’s Government, stated that Xinxiang City will take this feedback meeting as an opportunity, focus on the feedback from the supervision team and all relevant requirements, do its best to implement all the work, and vigorously promote the continuous improvement of the environmental situation. We should further improve our ideological understanding, strengthen the rectification of problems, address both the symptoms and the root causes, and be stricter in asking questions and accountability. Xinxiang City will firmly establish the concept of green development, fully implement the environmental protection principle of "Party and government share responsibility, double responsibility for one post and accountability for dereliction of duty", strengthen environmental protection with stricter measures, greater efforts and higher standards, and continuously improve environmental quality.

The "nucleic acid fever" in various places has subsided, and many places have clearly stated that normalized nucleic acid testing will be cancelled!

Since the Omicron epidemic swept through, normalized nucleic acid detection has become a standard in major cities.

In May this year, the relevant person in charge of National Health Commission said that a "sampling circle" of nucleic acid was established in big cities, and Henan even took the lead in announcing the implementation of 48-hour nucleic acid in the whole province.

However, recently, this high frequency, high investment and strict defense detection mode has been somewhat loose. According to media reports, in recent days, many places across the country have adjusted their epidemic prevention and control policies, canceled the normalized nucleic acid detection mechanism or canceled the inspection of nucleic acid certificates.

In the future, will we slowly bid farewell to the life of 48 or 72 hours of nucleic acid "continuation"?

No.1

8 explicitly cancel the normalization of nucleic acid detection.

"nucleic acid detection fever" began to cool down

Recently, the national nucleic acid testing fever has begun to "cool down", and normalized nucleic acid testing has been cancelled in many places. Some areas have now made it clear that normalized nucleic acid testing will be cancelled. The details are as follows:

Dezhou City, Shandong Province: On June 15th, Dezhou City, Shandong Province issued the Notice on Adjusting the Policy of Epidemic Prevention and Control, and the people in theaters no longer required the "48-hour nucleic acid test certificate".

Tongzhou bay Demonstration Zone, Jiangsu Province: On June 14th, the Joint Prevention and Control Command of COVID-19 Epidemic in tongzhou bay Demonstration Zone, Jiangsu Province announced that the routine inspection of regional nucleic acid detection would be suspended from June 14th.

Jixi County, Xuancheng City, Anhui Province: According to the notice of the Office of COVID-19 Epidemic Prevention and Control Headquarters in Jixi County, Xuancheng City, Anhui Province on June 13, in view of the fact that Jixi County is a low-risk area in the whole country, the nucleic acid detection work of "all-staff nucleic acid rotation inspection every 7 days" will be cancelled on June 14.

Huangshan High-tech Zone, Anhui Province: Prevention and Control of COVID-19 Epidemic in Huangshan High-tech Zone, Anhui Province. The notice of emergency headquarters on June 13th mentioned that due to the fact that the whole high-tech zone is a low-risk zone, the regional nucleic acid detection scheduled to be carried out every Thursday was cancelled, and the nucleic acid detection of key populations should continue to be carried out according to the prevention and control requirements.

Shexian County, Huangshan City, Anhui Province: Prevention and Control of COVID-19 Epidemic in Shexian County, Huangshan City, emergency headquarters also announced that the regional nucleic acid detection scheduled for June 13-14 was cancelled due to the low risk in Shexian County.

Hai ‘an, Jiangsu Province: According to the news of WeChat "Hai ‘an Release" on June 12, from June 13, Hai ‘an City, Jiangsu Province will suspend the normalization inspection of regional nucleic acid detection.

Huangshan Scenic Area, Anhui Province: On June 11th, emergency headquarters, an epidemic prevention and control center in Huangshan Scenic Area, Anhui Province, issued a notice. In view of the low risk of the whole area, the regional nucleic acid detection scheduled for Monday and Tuesday was cancelled.

Huizhou, Guangdong: According to the report of WeChat "Huizhou TV Station", starting from June 10, according to the work arrangements of the relevant departments of epidemic prevention and control in the city, Huizhou airport, railway station and bus station are no longer required to hold 48-hour negative proof of nucleic acid test.

No.2

National Health Commission: Checking nucleic acids should not become the norm.

"If there is no epidemic and there is no risk of input, it should not be a normal state to check nucleic acids." He Qinghua, the first-class inspector of National Health Commission CDC, clearly pointed out at the press conference of joint prevention and control mechanism in the State Council on June 9th that there is no need for frequent nucleic acid testing in low-risk areas and low-risk people, and the focus of nucleic acid testing should be on high-risk people and staff in high-risk positions, as well as areas with epidemic situation.

At the same time, the corrective action for normalized nucleic acid detection has never stopped. Recently, the number of new infections in Beijing increased sharply due to the cluster epidemic of "Paradise Bar". On June 15th, at the 366th press conference of novel coronavirus epidemic prevention and control work in Beijing, Xu Hejian, deputy director of the Propaganda Department of the Municipal Party Committee, spokesman of the municipal government and director of the municipal government information office, introduced that social prevention and control should be strictly and tightly carried out. Carry out high-quality nucleic acid screening, screen all the staff in key epidemic-related areas and towns with cases, find out the personnel base, strengthen organization and mobilization and information comparison, and ensure full coverage. Continue to do a good job in the normalization of nucleic acid testing in key industries and key populations, so as to ensure that all inspections should be completed.

According to relevant media reports, although large-scale nucleic acid testing is inevitable in the form of epidemic rebound, according to the characteristics of this epidemic, Beijing has specially positioned the people who should be inspected in key industries and key populations, which will minimize the impact of nucleic acid testing on the daily operation of the city to the greatest extent, and at the same time, accurately positioning the population will also reduce the workload for epidemic prevention workers, and ensure the personal rights and interests of medical staff to the greatest extent when emergencies come.

No.3

Optimization and Reform under Normalized Nucleic Acid

Free medical staff from nucleic acid testing!

Recently, National Health Commission issued two documents, namely, Guidelines for Preventing and Controlling Epidemic in novel coronavirus (hereinafter referred to as "Guidelines") and Notice on Further Strengthening the Quality Management of Nucleic Acid Sampling in Covid-19 (hereinafter referred to as "Notice"), to standardize the nucleic acid detection of epidemic prevention personnel and protect the personal rights and interests of medical staff.

The "Work Guide" requires further efforts to prevent heatstroke and labor protection for epidemic prevention and control personnel to prevent high temperature heatstroke. Many of them are equipped with heatstroke prevention drugs and drinks for epidemic prevention personnel; Reasonable control of high temperature operation time; Special people are not allowed to engage in intimate measures such as high-temperature operations (detailed report on one-click direct access).

The "Notice" clearly requires that "the deployment and use of sampling personnel should not crowd out normal medical resources as much as possible to ensure the people’s demand for medical treatment", and further free medical staff from nucleic acid testing (one-click direct report in detail).

Insiders pointed out that how to carry out nucleic acid testing, whether it needs normalization and where large-scale nucleic acid is needed, in the three-year epidemic experience, the government and the people have the answers in their hearts, and the process of the government’s continuous optimization of policies and measures is the process of correcting and improving, which takes some time.

At the same time, some people said that the question of who will do the nucleic acid testing is worthy of further discussion and analysis. In the process of round after round of epidemic rebound, the hard work of medical staff is in everyone’s eyes, but in the face of the frequent occurrence of "lightning storms" in testing institutions, the issue of opening up the market access for nucleic acid testing will be pushed to the forefront of public opinion. How to carry out the task of nucleic acid testing "treating both the symptoms and the root causes" needs in-depth research and discussion in many aspects.

Under the influence of the reform of drug evaluation and approval system and multiple favorable factors, the process of listing new drugs in China has been accelerated, and local innovative pharmaceutical companies have begun to rise. Although chemical drugs and biological products have occupied the mainstream of the market, with the continuous implementation of the support policy for innovative drugs of traditional Chinese medicine, innovative research and development of traditional Chinese medicine has also made breakthrough progress, stepping on the wave of the times to usher in spring.

Traditional Chinese medicine (TCM) has made remarkable achievements in its inheritance and development for more than two thousand years. How to push the great wealth left by our ancestors to the world has always been the direction explored by generations. No matter how the times change, inheritance and innovation are always the two main lines of developing Chinese medicine.

I believe that in the next few years, with the continuous implementation of the basic policies for the innovation and development of traditional Chinese medicine, Chinese medicine enterprises will have the opportunity to resonate with the development of industries and policies. It is expected that in the future, innovative drugs of traditional Chinese medicine will go to a higher level on the innovation system that domestic western medicine has built, not only doing well in China, but also occupying a place in the world.

Self-heating rice is a convenient food.

however

It is targeted by criminals.

Use it to transport drugs.

Recently, the police in Xishui County, Huanggang City, Hubei Province announced that they had cracked a gang case suspected of using fast food packaging to transport drugs, and the case has entered the court trial stage.

In July 2021, in a residential area in Huanggang City, Hubei Province, dozens of plainclothes policemen outflanked two young men in multiple ways, and one of them was quickly subdued by the police who had just taken out the parcel from a courier point.

The police opened the two boxes of parcels they had just taken out layer by layer, and dozens of boxes of self-heating rice packets were neatly coded inside, but when the police opened the seal, they found a lot of drugs hidden in it.

Anti-drug police of Xishui County Public Security Bureau in Huanggang, Hubei Province;

When we arrested Wang, we seized two boxes of drugs hidden in self-heated rice, about 20 thousand. If he finally confessed himself, he still had a batch of goods on the road and arrived at Huanggang Express Transfer Station the next day. A total of 34,000 pieces were destroyed this time.

According to the police, hemp fruit is a processed ice tablet, and its main component is ice. In this arrest by the Xishui police in Huanggang, Hubei, Wang, the principal criminal of the gang, was seized by the police when he received the express parcel containing hemp fruit. After investigation, this batch of drug-related parcels was transported to Huanggang, Hubei by express delivery from the Yunnan border, and both the sender and the recipient were the same person.

The secret investigation by the police of the task force found that every time Wang’s gang disguised drugs at different levels and delivered them to Hubei by express delivery, they would return to Huanggang to attract drug traffickers to lower-level networks for distribution.

Anti-drug police of Xishui County Public Security Bureau in Huanggang, Hubei Province;

During our investigation, we found that they crossed the border illegally, and the backpacker handed the drugs back to him. He delivered the drugs to our mainland through logistics at a courier point in Xishuangbanna. Every time Wang went by plane, after the goods were delivered to the express delivery point that day, he immediately bought tickets and flew back to achieve the purpose of "separation of people and goods" and escaped the blow.

The suspect, Wang, confessed that he found that the self-heating rice in the portable package was very concealed, so he bought a large number of self-heating rice and split it. After packaging the drugs layer by layer, he used the self-purchased plastic machine to restore it to its original state, in order to escape the express delivery. Unpacking inspection and security measures.

Anti-drug police of Xishui County Public Security Bureau in Huanggang, Hubei Province;

Wang carried out a layer of tin foil packaging on the outside of drugs, and the role of tin foil packaging was to prevent the X-ray machine of express logistics from finding out. Second, a layer of plastic wrap is used to prevent the smell of hemp fruit from being revealed. For example, there are drug detection dogs in some places, and if the smell of hemp fruit is relatively strong, it is easy to be found.

According to the police, after four centralized arrests, 45 drug addicts were arrested, 34,000 pieces of hemp fruit, more than 350 grams of ice, and some marijuana were seized. At the same time, an imitation 64 pistol was seized, with two bullets, more than 1 million yuan of drug money was seized, and six vehicles were seized, which successfully destroyed this drug trafficking gang entrenched in eastern Hubei.

Recently, the Xishui County People’s Court held a public hearing on the case. Twelve defendants were suspected of drug trafficking, illegal sale and purchase of guns, illegal possession of drugs, hosts of others, robbery and many other crimes.

What other means do drug dealers have to hide drugs?

Brown sugar hides poison.

When the police inspected a courier car, they found that a courier parcel was particularly heavy and the delivery address was unknown. After moving the parcel into an X-ray machine for scanning, they found that there were granular items inside the parcel and it was suspected that drugs were hidden. After further unpacking inspection, it was found that the carton was full of lump brown sugar wrapped in bamboo leaves. The police on duty cut the brown sugar and seized 6.695 kilograms of ice from 16 pieces of brown sugar.

Dried radish hides poison.

The police learned at work that someone sent drugs by express delivery. Immediately, the police checked all the packages. When checking two packages containing dried radish, they found that the middle of the strip-shaped dried radish was swollen. When they opened it, they found that there were ice granules wrapped in transparent plastic in the middle of the dried radish. After the police opened all six cans of dried radish, they seized 1.09 kilograms of ice granules.

Vase holds poison.

The police learned that a courier logistics vehicle contained drugs, and put it under control to find the suspected vehicle. After nearly a thousand kilometers of long-distance tracking, the police arrested the receivers Chen Mou and Shen near a university. The police seized a total of 5.932 kilograms of ice in the carton vases received by the two.

Latex pillow hides poison

The anti-drug department found 50 bags of drug Ma Gu (102,000 pills in total, weighing 9.71533 kilograms) in a latex pillow package found at the international express outlet of the airport.

Coffee powder hides poison.

When investigating the case, the anti-drug police found a parcel with suspected drug-related clues, and seized 12.5 grams of ice and a batch of smoking tools hidden in coffee powder from the parcel they received.

summary

Article 347 of the Criminal Law of People’s Republic of China (PRC) stipulates that whoever smuggles, sells, transports or manufactures drugs, regardless of the quantity, shall be investigated for criminal responsibility and given criminal punishment.

The French Open is long and sparse, but fancy possession of drugs can’t escape the attention of the police after all. The disguise of drugs is constantly updating and iterating, so we should be vigilant and avoid putting ourselves in jail.

　　CCTV News:As the bell of the 2018 New Year is about to ring, the annual New Year message from the Supreme Leader of president arrives as scheduled. This is the fifth time that the Supreme Leader has delivered a New Year message since he took office in president, and it is also the first New Year message after Socialism with Chinese characteristics entered a new era.

　　Looking back on the New Year greetings of the Supreme Leader in the past five years, "people" is undoubtedly a high-frequency word. In the New Year message in 2014, "people" appeared 9 times, 16 times in 2015, 12 times in 2016 and 10 times in 2017. This time, the New Year message "people" appeared 14 times and "masses" appeared 6 times, which fully shows the weight of "people" in the hearts of the supreme leader.

　　Do not forget your initiative mind does practical things for the people.

　　Recently, "Sun’s 18-year-old photo" swept the circle of friends, and many people were moved by their own or others’ memories of youth.

　　Photos of the supreme leader’s youth also appeared in this New Year message video. In his youth, the Supreme Leader went to the countryside of northern Shaanxi as an educated youth and stayed there for seven years. There, dams, roads, biogas and terraces are built &hellip; &hellip; Do all kinds of hard work. In the eyes of the villagers, the supreme leader is a "hard-working, good young man."

　　Supreme leader’s youth military uniform photo

　　The Supreme Leader recalled in an article: "When I came to the Yellow Land at the age of 15, I was lost and confused; When I left the yellow land at the age of 22, I had a firm goal in life and was full of confidence. As a public servant of the people, the northern Shaanxi Plateau is my root, because it has cultivated my unchanging belief: to do practical things for the people! "

　　Everything goes forward, and we must not forget the road we have traveled; No matter how far you go, you can’t forget the past and why you set out.

　　From Shaanxi to Beijing, from Hebei to Fujian, from Zhejiang to Shanghai, from the grassroots to the party and state leaders, and the supreme leader who came out of the yellow land, the initial intention of "let the folks live a good life" is consistent.

　　"Keep the safety of ordinary people in mind at all times, take the benefit of the people as the greatest achievement, think about what the masses think, worry about what the masses are anxious, and make people’s lives happier." This is the supreme leader’s earnest expectation for Party committees, governments and cadres at all levels in his New Year message, and it also declares his determination to lead the Communist Party of China (CPC) to govern for the people.　　　

　　In the past 2017, China’s GDP reached 80 trillion yuan, more than 13 million new jobs were created in urban and rural areas, more than 900 million people were covered by social old-age insurance, 1.35 billion people were covered by basic medical insurance, and more than 10 million rural poor people were lifted out of poverty, and 3.4 million poor people moved out of poverty and had warm new homes. 6 million sets of target tasks were completed ahead of schedule in the number of shantytown renovation projects. The development of various livelihood undertakings has been accelerated, the ecological environment has been gradually improved, and the people have more sense of gain, happiness and security.

　　Think what the masses think and be anxious about what the masses are anxious about.

　　"I understand that the people are most concerned about education, employment, income, social security, medical care, old-age care, housing, environment and other things. Everyone has a lot of gains, but also a lot of worries and troubles."

　　The word "understanding" embodies the ruling style of the supreme leader who loves the people and the people.

　　What the people need, what they do. Since the 18th National Congress of the Communist Party of China, the supreme leader’s investigation and research has spread all over the country, and his footprints have been left in communities, villages, enterprises, schools and troops.

　　"Go to the places where the masses need it most to solve problems, and go to the places where development is most difficult to open up the situation." In 2013, the supreme leader said this sentence in Gansu, which made the people-oriented thought of a big country leader deeply rooted in the hearts of the people.

　　Demo is higher than loving the people. In the grass-roots investigations again and again, the top leaders took the lead in setting an example, showing in detail how leading cadres should be close to the people and love the people. Baoding, Hebei province, he talks with villagers in a poor village deep in Taihang Mountain. In Lanzhou, Gansu, he served a meal for a 70-year-old man in a restaurant; In Hainan, he happily put on the hat handed by the Li people; In Xuzhou, Jiangsu Province, he spent 30 yuan to buy the villagers’ handmade sachets, and gave them to the 80-year-old villagers &hellip; &hellip;

　　Poverty alleviation is the most touching "people’s feelings". The rate of poverty reduction of more than 10 million a year is a miracle in China and even in the history of the world.

　　The supreme leader once said: as long as there is still a family and even a person who has not solved the basic living problems, we can’t be comfortable; As long as the people’s longing for a happy life has not come true, we must unite and lead the people to struggle together.

　　In February 2016, the Supreme Leader made an investigation in Jiangxi. In the poor household Zhang Chengde’s home, the supreme leader went room by room to see how he ate, whether he lived warmly and how many channels he could watch on TV. (Source: Xinhua News Agency)

　　In the face of the difficult masses, the supreme leader has always been modest and amiable. In 2016, when he was investigating in Jiangxi, he came to the home of poor household Zhang Chengde, inspected the kitchen, bedroom, sheepfold, doll fish pond and flush toilet. Zhang Chengde’s wife took the hand of the general secretary and said excitedly, "Thank you for coming to see us. You are the head of the country." The supreme leader took over the conversation and said, "The people are the masters of the country, and we are the servants of the people to help you run your errands."

　　In the course of the visit, we found the details that need to be improved, and the supreme leader will personally propose solutions. When investigating in Zhangjiakou, Hebei Province, he gave advice to the planning of local farmyard, and proposed that the living area, production area and breeding area of the house should be rationally laid out, the problem of toilet improvement should be scientifically designed, and public opinion should be respected.

　　Asking what is needed by the people solves people’s worries and warms people’s hearts.

　　"By 2020, the rural poor will be lifted out of poverty under China’s current standards!" On the road to a well-off society in an all-round way, the supreme leader has a far-reaching plan. By 2020, there will be only three years, and the whole society should take action, make the best of it, make precise policies, and constantly win new victories.

　　There is no doubt that winning the battle against poverty as scheduled in three years will be the first time in the history of the Chinese nation for thousands of years to eliminate absolute poverty as a whole, which is of great significance to the Chinese nation and the whole mankind.

　　Building a community of human destiny for the benefit of people all over the world.

　　"Sharing" is undoubtedly a "hot word" in 2017.

　　"Our great development achievements are created by the people and should be shared by the people."

　　Heaven rewards diligence and changes with each passing day. In 2017, China held the The 19th National Congress of the Communist Party of China, which painted a beautiful blueprint for Socialism with Chinese characteristics in the new era and started a new journey of building a socialist modern country in an all-round way.

　　A nine-story platform starts from tired soil. Looking forward to the new year, we will continue to make efforts to build a well-off society in an all-round way, implement the 13 th Five-Year Plan and comprehensively deepen reforms. As the supreme leader said in his New Year message: "Don’t dwell on fantasy, don’t dwell on empty voices, do a good job step by step."

　　The people of China are concerned about the future of their own country and the future of the world. Not only do you want to live well, but you also want people of all countries to live well.

　　In 2017, China hosted many home-based diplomatic activities, including the first Belt and Road International Cooperation Summit Forum, the meeting of BRICS leaders in Xiamen, and the high-level dialogue between the Communist Party of China (CPC) and world political parties. At the same time, the top leaders also participated in many important international multilateral conferences.

　　On these different occasions, the supreme leader has in-depth exchanges with all parties to promote the building of a community of human destiny for the benefit of people all over the world.

　　In the five-year New Year message, the Supreme Leader sincerely hopes that people all over the world will understand and help each other in the process of realizing their dreams, and strive to build the earth on which we live into a common and beautiful home.

　　The world is a family. In his New Year message, the Supreme Leader pointed out: China firmly upholds the authority and status of the United Nations, actively fulfills its due international obligations and responsibilities, abides by its commitment to tackling global climate change, actively promotes the joint construction of the Belt and Road Initiative, and always remains a builder of world peace, a contributor to global development and a defender of the international order.

List of Main Popularizing Techniques and Leading Varieties of Four Major Grain Crops in 2004

　

The first part of the 10 main push technology

　　I. Rice

　　(A) Rice dry cultivation and sparse planting technology

　　Dry-raised and sparse planting technology of rice is a high-yield cultivation technology combining dry-raised seedlings with reasonable sparse planting. On the basis of introducing and absorbing Japan’s dry cultivation and sparse planting technology in cold regions, this technology has been improved and perfected according to different ecological environments, production conditions and technical levels, forming a unique dry cultivation and sparse planting technology system. Dry seedling cultivation is to cultivate rice seedlings near dry land. There is enough oxygen in the dry land soil, and water, heat and fertilizer are easy to coordinate, which is conducive to cultivating strong seedlings. Taking advantage of strong seedlings, planting density can be appropriately reduced in Honda, tillering can be used to form panicles, and scientific fertilizer and water regulation methods can be used to achieve large panicles and more grains, stable and high yield.

　　The main advantages of this technology are: (1) short and strong seedlings, strong root activity and good cold resistance; (2) After planting, it grows fast, tillers vigorously, the rate of ear formation is high, and the ear is big and the grain is more fruitful. (3) Early sowing, early planting and early maturity, generally 3-5 days earlier than conventional cultivation; (4) The benefits of increasing production and saving cost are good, generally about 50kg more rice than that of conventional cultivation. At the same time, 80% rice seedlings and 80% plastic film are saved, and 20-50% seeds are saved, which can also save labor, fertilizer and water.

　　This technology is not only suitable for popularization and application in the northern single-cropping rice area, but also suitable for popularization and application in the southern double-cropping rice area, with obvious yield increase and efficiency increase. At the same time, it is of great significance to solve the problems of low-temperature seedling rot and late emergence of stiff seedlings after planting during the seedling raising of double-cropping early rice, expand the area of late-maturing varieties, ensure early transplanting and high yield of continuous cropping late rice, and promote rice production to a new level. This technology has been widely used in various rice areas in China, with an annual application area of more than 100 million mu. This technology won the second prize of National Science and Technology Progress Award.

　　(B) Rice seedling throwing technology

　　Rice seedling throwing technology is a kind of rice cultivation method which uses plastic seedling tray or dry seedling bed to cultivate seedlings with nutrient clods at the roots, and uses the gravity of the seedlings with soil to evenly scatter the seedlings to the field manually or mechanically when transplanting. It is a major reform of rice cultivation technology.According to different seedling raising methods, rice seedling throwing can be divided into plastic tray seedling throwing, paper tube seedling throwing, dry seedling throwing without tray and interlayer seedling throwing, etc. At present, plastic tray seedling throwing is widely used.

　　Compared with traditional manual transplanting, this technology can save 0.1 mu of rice field per mu, save 2-3 workers, save about 30% of production cost, increase production by 5%-10%, and increase benefits by 15%-20%. At the same time, it can throw seedlings standing without bending over, greatly reducing labor intensity, and is conducive to centralized seedling raising in pieces, promoting large-scale operation and socialized service of rice production. Therefore, Especially in rice producing areas with developed economy and education, lack of agricultural labor and high labor price, this technology is more widely used. According to statistics, the application area of rice seedling throwing in China increased from more than 500,000 mu in 1990 to more than 100 million mu in 2000, nearly 200 times in 10 years.

　　In recent years, China Rice Research Institute has conducted research on rice double-season seedling throwing technology by selecting new high-quality rice varieties, and assembled and integrated a supporting technology of rice double-season high-quality rice varieties, double-season seedling throwing and double-thousand-kilo rice yield per mu, which is referred to as "rice double-excellent double-throw double-kilo technology".

　　(3) Mechanized rice transplanting technology

　　Mechanized rice transplanting refers to a kind of mechanized rice planting technology that uses rice transplanter to transplant rice instead of manual transplanting. It can greatly improve the production efficiency and reduce the labor intensity of farmers in the field, and has important popularization and application value for China, especially the economically developed southeast coastal areas, to take the lead in realizing agricultural modernization. According to the experimental research results of our institute for many years, mechanical transplanting has good operation quality and good agronomic characters in the field, which is beneficial to high and stable yield of rice. The experimental demonstration shows that compared with manual transplanting, the yield of rice mechanical transplanting is basically the same or has a certain effect of increasing production; The disease of rice transplanted mechanically is mild and the density of insect pests is low. Compared with manual transplanting, mechanical transplanting reduces labor cost by 30-50 yuan per mu, and greatly reduces farmers’ field labor intensity. Mechanical transplanting saves labor and time, which can effectively improve agricultural production efficiency and agricultural modernization level.

　　(D) No-tillage cultivation techniques of rice

　　No-tillage cultivation technology of rice refers to a rice cultivation technology which uses herbicides to kill weed plants and seedlings of falling grain after harvesting crops in the previous season or rice fields that have not been plowed and raked after idle, destroys rice stubble or green manure crops, irrigates and fertilizes the fields, and after the water layer naturally dries or drains, carries out direct seeding or transplanting to plant rice, and then carries out cultivation management according to the growth characteristics of no-tillage. It has changed the traditional tillage cultivation practice and directly leveled the ground.

　　This technology has the advantages of saving labor and cost, simplicity, improving labor productivity, easing seasonal contradictions, reducing soil erosion, protecting soil, protecting ecological balance and increasing economic benefits. According to the experimental demonstration results of China Rice Research Institute, the cost of medicine per mu in no-tillage paddy fields is about 25 yuan, which can increase production by 8%~10%, which can save costs and increase efficiency by 40-55 yuan compared with conventional paddy fields. No-tillage cultivation of rice can not only increase the yield, reduce the cost, not miss the farming season and reduce the labor intensity, but also improve the physical and chemical properties of soil, reduce soil erosion and develop sustainable agriculture, so it is popular among farmers. No-tillage cultivation has great popularization value and application prospect under the new rural situation that the comparative benefit of growing grain is low and farmers go out to work more.

　　Second, wheat

　　(1) Precision and semi-precision sowing techniques of wheat

　　With the improvement of production conditions and the improvement of wheat yield level, the contradiction between high yield and lodging has become increasingly prominent under the traditional cultivation conditions (big water, big fertilizer and large sowing amount), which not only affects the further improvement of wheat yield, but also makes the benefit of wheat production seriously decline. In order to solve the contradiction between high yield and lodging under medium and high yield conditions and promote the further improvement of wheat yield, the cultivation techniques of precision sowing and semi-precision sowing of wheat were studied and put forward.

　　① Biological basis of precision sowing and semi-precision sowing cultivation of wheat

　　Reduce basic seedlings and cultivate strong seedlings. Under the traditional cultivation conditions, the basic seedlings per mu are generally 200,000-300,000, and the number of seedlings is too large, and the wheat seedlings compete for water, fertilizer and glory seriously, and the quality of wheat seedlings is poor. Precision sowing and semi-precision sowing of wheat can cultivate 60,000-120,000 basic seedlings per mu (Huanghuai wheat area), and the nutritional conditions and safe living space of single wheat seedling are greatly improved, which is conducive to cultivating strong seedlings and laying the foundation for high yield.

　　Rely on tillering to form panicles, and increase the proportion of multi-panicle plants in the population. The population composed mainly of multi-panicle plants (tillering panicles) has high panicle yield, while the population composed mainly of one-panicle plants (main stem panicles) has low yield. Precision sowing and semi-precision sowing cultivated wheat fields have fewer basic seedlings, more panicles per plant, mainly multi-panicle plants, and higher yield.

　　There are many panicles per plant, large panicles and many grains, and high 1000-grain weight. In a certain range, there is a significant positive correlation between the number of panicles per plant and the average number of grains per panicle and 1000-grain weight. The wheat plants cultivated by precision sowing and semi-precision sowing are robust, with not only more panicles per plant, but also large panicles, more average grains per panicle and higher average 1000-grain weight. ② Advantages of precision sowing and semi-precision sowing cultivation of wheat.

　　Improve the ventilation and light transmission conditions in the field. Precision sowing and semi-precision sowing cultivation of wheat greatly reduced the number of basic seedlings per unit area, improved the ventilation and light transmission conditions in the field and reduced the humidity in the field, which not only helped to inhibit the occurrence of common diseases of wheat, but also significantly improved the lodging resistance of wheat.

　　It improves the photosynthetic performance of the population and is beneficial to the accumulation and distribution of dry matter. Precision sowing and semi-precision sowing cultivation of wheat not only significantly improved the photosynthetic intensity of the population in the late growth stage, but also promoted the transportation of photosynthetic products to the ear, which was beneficial to improve the economic coefficient and grain yield.

　　The absorption capacity of root system is enhanced, and the production efficiency of water and fertilizer is improved. Precision sowing and semi-precision sowing wheat have more secondary roots, developed roots, wide nutrient range and strong root activity, so they have strong absorption ability of fertilizer and water. In addition, precision sowing and semi-precision sowing wheat have higher economic coefficient, so the production efficiency of water and fertilizer is higher.

　　(2) High-efficiency cultivation techniques of ridge cultivation of wheat

　　This technology is a wheat planting technology widely adopted by Mexican farmers in 1980s. It has the advantages of saving water and fertilizer, reducing the production cost by about 30% and being easy to manage, etc., and it was quickly popularized in a large area in Mexico, with the current coverage exceeding 90%.

　　Compared with traditional flat cultivation techniques, ridge cultivation techniques have the following characteristics:

　　1. The traditional flat flood irrigation was changed into furrow infiltration irrigation, which eliminated the phenomenon of soil hardening caused by flood irrigation and the soil became sticky with the increase of irrigation times, and created favorable conditions for the robust growth of wheat. Moreover, the water consumption for one irrigation was only about 30 cubic meters/mu, saving water by 30-40%.

　　2. Top dressing of ridge wheat is concentrated strip application in furrow, which can be done manually or mechanically. If it is done manually, each person can topdress 30 mu a day, which greatly improves the labor efficiency. The fertilizer is applied to the bottom of the ditch in a centralized way, which increases the fertilization depth (because the height of the ridge is 17-20 cm, and the fertilizer is applied to the bottom of the ditch, which is equivalent to the fertilization depth of 17-20 cm), and the fertilizer utilization rate can reach 40-50% in the current season.

　　3. Ridge planting is the planting method of ridge planting, and the soil surface of traditional flat planting is changed to be wavy, which increases the soil surface area by about 30%, and the light interception also increases correspondingly, which significantly improves the ventilation and light transmission conditions in the wheat canopy, increases the light transmittance by 10%-15%, reduces the field humidity by 10%-20%, and reduces the incidence of wheat powdery mildew and wheat sheath blight by 40%; The length of basal internodes of wheat was shortened by 3-5 cm, and the plant height of wheat was reduced by 5-7 cm, which significantly improved the lodging resistance of wheat.

　　4. Ridge cultivation has changed the field configuration of traditional flat-planting wheat, that is, it is beneficial to give full play to the lateral advantages of wheat by changing the equal row spacing to large and small rows, and the 1000-grain weight has increased by about 5% and the yield has increased by 5%-10%.

　　5. Ridge cultivation of wheat creates favorable conditions for interplanting corn. Planting wheat on the ridge and interplanting corn at the bottom of the ridge not only facilitates field operation, but also improves the growth conditions of corn, which is conducive to increasing the annual grain output per unit area.

　　Third, corn

　　(A) less, no-tillage mulch direct seeding technology

　　1, technical content

　　No-tillage and mulching direct seeding technology is a major form of Conservation Tillage. It is a soil conservation tillage method developed abroad and popularized and perfected in China. It refers to the tillage and planting system in which the surface stubble coverage is at least 30% after one crop, and the soil erosion is controlled at about 50%. Its technical system is a set of farming technology system combining agronomy and agricultural machinery, which adopts less (no) tillage, mulching and other tillage methods, combined with the application of herbicides, to reduce the frequency of intertillage weeding, so as to reduce the disturbance and damage to the soil, increase the surface stubble, and maintain water and soil resources, so that the soil can maintain relatively high yield.

　　No-tillage mulch direct seeding of maize mainly includes three technical operations: (1) Water conservation and drought resistance technology of previous crop mulching: after the previous crop is harvested, a certain amount of crop stubble is reserved to cover the surface, and the coverage is aboutPer mu100－200Kilogram.A large area in Northeast China is continuous cropping of corn, which can be directly sown without tillage by staggering previous crops or by strip rotation. If the previous crop is wheat, the wheat is harvested by a 1065 combine harvester → the wheat straw is crushed by a vertical claw type wheat straw crusher, and the straws are spread at the same time, and the plots with more straws are bundled by a bundling machine to prevent the straws from piling up and blocking the no-tillage seeder; (2) No-tillage sowing technology of corn: Adjust the row spacing and sowing amount of the seeder according to the yield target, and choose a model with good selectivity. The 2BQM-6A developed by China Agricultural University has the characteristics of good stubble breaking, fine precision air-suction sowing and stable sowing quality. The small corn no-tillage seeder produced by Nonghaha has the characteristics of small size and portability, and is suitable for small-area farmers. Corn seeds under conservation tillage should be coated. The sowing amount of corn depends on the planned density. The sowing amount of silage corn harvested by green body is about 20% higher than that of corn harvested by grain, and foot fertilizer and seed fertilizer are applied when sowing. (3) Chemical weeding technology: chemical weeding should be carried out before sowing, and the herbicide should be determined according to the grass phase of weeds in the field. If the effect of weeding before sowing is not good, a herbicide harmless to corn can be sprayed after sowing, such as Yunongle.

　　2. Technical effect

　　The production of corn for conservation tillage has the following advantages in Northeast China: (1) Less no-tillage direct seeding saves farmland operation and operation cost, and the sowing date is 1-2 days earlier than that of conventional flat sowing. In case of rainy days, no-tillage will show the effect of increasing production in time; (2) The farmland-free blocks have strong water storage and moisture conservation capacity. Because the surface is covered with straw, the water, fertilizer, gas and heat of the soil can be supplied in harmony, and the soil is not easy to crack during drought and accumulate water after rain. Compared with ploughed corn, it grows faster and has a good seedling condition. In addition, the fertilizer is not easy to lose, and the yield is also improved accordingly; (3) The lodging resistance of maize is good. No-tillage corn has more surface roots and developed taproots, and the original soil structure has not been destroyed, so the corn root system has strong consolidation ability with soil, so the lodging resistance of corn is strong; (4) Returning wheat straw to field increased soil organic matter content, improved soil fertility and improved soil structure; (5) It has an obvious cost-saving and synergistic effect. Compared with ploughed plots, the non-cultivated plots of corn increase corn by 765 kg/ha, which reduces farmland operation, reduces watering once during the growth period of corn, and saves water and oil.

　　(B) Low-moisture corn cultivation techniques

　　The high moisture content of grain and the decline of product quality are also one of the important limiting factors of corn production in Northeast China-Inner Mongolia, so it is very important to produce low moisture corn, especially special corn for industrial processing. The main measures are as follows: firstly, we should choose varieties that can mature normally before frost, and in areas with insufficient heat, we should choose varieties with early maturity, high yield and high quality, and varieties with fast filling rate and rapid dehydration; Secondly, planting suitable density (generally 3000-4000 plants/mu) according to the characteristics of varieties, and properly carrying out field management to promote early maturity; The third is field precipitation technology, which can be used to remove bracts and dry them in the sun 50-55 days after spinning. Appropriate drying methods should be carried out if conditions permit; The fourth is yard precipitation, using small stations with a diameter less than 1.5 meters for precipitation.

　　It can obviously improve the yield of dry-farming corn, promote the early maturity of corn and reduce the water content of corn seeds during maturity, which is beneficial to improve the quality of special corn.

　　Fourth, soybeans

　　(A) Narrow row close planting technology

　　Narrow row and close planting cultivation technology of soybean is a high-yield cultivation technology of narrow row and close planting of soybean, which is based on introducing, digesting and grafting foreign flat planting and narrow row and close planting technology, combined with the natural characteristics and production conditions of Heilongjiang Province. Its core is the planting technology of selecting short or semi-short varieties, reducing row spacing and increasing density, which generally increases the yield by more than 15% compared with ridge three cultivation. It includes three modes: flat planting with narrow rows, large ridge with narrow rows and small ridge with narrow rows. Under the current conditions, flat cultivation with narrow rows and close planting is suitable for areas with high mechanization level, good chemical weeding technology and less land. Close planting with large ridges and narrow rows is suitable for areas with rich heat resources, high soil fertility and meticulous cultivation management; Narrow row and close planting in small ridges is more suitable for areas with low soil fertility and cooler areas.

　　The technical points are as follows: firstly, dwarf and semi-dwarf lodging-resistant varieties are selected, which are suitable for narrow rows and close planting. Second, it is necessary to create a good soil plough layer condition and increase fertilizer input for narrow row and close planting. Flat cultivation with narrow rows and close planting, without shoveling during the growth period, weakens the ability of warming, drought prevention and waterlogging resistance. It requires a good soil tillage layer condition. In order to achieve deep tillage layer, flat surface and fine soil, close planting with large ridges and narrow rows is adopted. Because the number of rows on the ridges increases the difficulty of mechanical sowing, the requirements for soil preparation are more stringent than those of conventional ridge cultivation, which requires not only deep tillage layer, but also flat surface soil on the ridges. In order to achieve high yield, it is necessary to increase the input of fertilizer and apply it reasonably. The first is to increase the application of agricultural fertilizer, and the application amount of medium fertility plots is 22.5.t/haAbove all, the fertilizer should be combined with nitrogen, phosphorus and potassium, and the application amount should be increased by more than 15% compared with that of conventional ridge farming. If conditions permit, soil testing and formula fertilization should be carried out, and trace element fertilizers should be applied according to local conditions. Third, chemical weeding must be done well. Because it is difficult to work in the field during the growth period of narrow row and close planting, it is necessary to do a good job of chemical weeding before sowing or after sowing and before seedling. According to the local weed community, we should choose herbicides with good effect and little pollution, and adopt strict techniques to realize one-time thorough weeding to prevent grass shortage. The fourth is to select suitable sowing machinery for precision sowing.

　　The 24-row seeder or the combined seeder produced by John Deer Company can be used for flat cultivation and narrow row close planting, and the 1.4m precision seeder developed by Dongnong and driven by small four wheels can also be used. The sowing row spacing is 15-30cm.

　　The large ridges are densely planted in narrow rows, and the mechanical ridges are sown with equidistance precision according to rows, and the three ridges are changed into large ridges with the ridge spacing of 90-105 cm, and the seeds are sown with a four-row seeder on the ridge produced by Hailun Agricultural Machinery Repair Factory, etc. For the big ridge with the ridge spacing of 120-140 cm from two ridges to one ridge, six rows were sown on the ridge with Huafeng 2B KM-IB special seeder for big ridge and narrow row in Huachuan.

　　(B) Ridge three cultivation techniques

　　This technology is a comprehensive high-yield cultivation technology of soybean with three technologies as the core: subsoiling, deep fertilization and precision sowing. Based on the success of popularizing soybean precision sowing in Heilongjiang Province, this new technology is a comprehensive high-yield cultivation technology of soybean, which combines the successful experience of popularizing subsoiling tillage in the 1970s with the practice of subsoiling soil with the "three ridges" tillage and sowing machine developed by "August 1st" Agricultural Reclamation University. It is mainly suitable for popularization in most soybean producing areas in Heilongjiang and Inner Mongolia, and generally increases the yield by more than 20% compared with conventional cultivation.

　　The mechanism of increasing yield is as follows: firstly, subsoiling can break the plough bottom, deepen the plough layer and improve the structure of the plough layer, which is beneficial to the growth and development of soybean root system and the formation of nodules. Subsoiling creates a soil structure that is virtual and real, and enhances the ability of soil to store water and conserve moisture and prevent drought and waterlogging. Subsoiling can also release cold and increase temperature, loosen soil and promote early growth and rapid development of soybeans; Second, the deep application of chemical fertilizer overcomes the phenomenon of burning seeds and seedlings in the same place, and at the same time can reduce the volatilization and loss of chemical fertilizer and improve the utilization rate of chemical fertilizer; Thirdly, on the basis of reasonable and close planting, the implementation of precision sowing can achieve even distribution of plants, solve the problems of uneven thickness and lack of seedlings in soybean production in the past, improve the growth environment of soybean plants, make the population structure more reasonable, and better coordinate the contradiction between light, heat, water and fertilizer.

　　Main technical points: First, subsoil the soil. The depth of subsoiling shall be subject to breaking the plow bottom, and generally the depth of subsoiling is 25-30cm. According to the different parts of subsoiling, it can be divided into ridge subsoiling, furrow subsoiling and omni-directional subsoiling. Deep loosening of ridges is also called deep loosening at the bottom of ridges. There are two methods: one is deep loosening of soil preparation, which is also called deep loosening and ridging. This method is combined with soil preparation, such as deep loosening of wheat stubble and deep loosening and ridging on the basis of ploughing or harrowing stubble. Another kind of subsoiling of ridges is subsoiling sowing. A large-scale "three-ridge" cultivator is used to subsoil the ridges, and at the same time, deep fertilization and precise sowing are carried out. This method is completed by three techniques at one time. Deep loosening of furrows means deep loosening of furrows with a deep loosening shovel. According to different periods, it can be divided into furrow subsoiling after sowing and before emergence, furrow subsoiling at seedling stage, etc., or furrow subsoiling can be carried out at the same time by using a small furrow cultivator. Omni-directional subsoiling refers to subsoiling the whole tillage layer with an omni-directional subsoiler, which can ensure that the soil layer is not chaotic and deepen the tillage layer, and the subsoiling depth can reach more than 50cm. The second is deep fertilization in layers, with chemical fertilizer as seed fertilizer, and the fertilization depth should reach 5-6 cm below the seed; Chemical fertilizer is used as base fertilizer, and the fertilization depth should reach 10-15cm. At present, the small precision seeders produced by agricultural machinery factories in Huachuan, Mingshui, Dedu and other counties (cities) can achieve deep fertilization; The large-scale "three ridges" tillage seeder produced by Yilan and Helen can not only achieve deep fertilization, but also achieve simultaneous application of seed fertilizer and base fertilizer, that is, layered fertilization. The third is precision sowing.At present, except in places with sufficient labor force, farmers also use artificial precision sowing methods such as artificial piercing and artificial seed placement, and most places have adopted mechanical precision sowing. Mechanical precision sowing can achieve continuous operations of ditching, sowing seeds, fertilizing, covering soil and suppressing, which not only speeds up the sowing progress, shortens the sowing period, but also ensures the sowing quality. To use mechanical precision sowing, first of all, we should do a good job in mechanical maintenance, especially the seed metering, fertilizer discharging and ditching and soil covering devices should meet the standards to reach the state of sowing operation; Second, do a good job in seed selection and germination test; The third is to do a good job in seed dressing or seed coating. When sowing, mechanical double-row equidistant precision sowing is carried out on the ridge, and the small row spacing between the two rows is 10-12 cm; Use a hole seeder to sow holes on the ridge at equal intervals, with the hole spacing of 18-20 cm and 3-4 plants per hole. It is necessary to appropriately increase the sowing amount and ensure that there are enough seedlings per unit area, with 200,000-300,000 plants per hectare in the central and southern regions and 280,000-350,000 plants per hectare in the northern region. In addition, we should also pay attention to selecting suitable varieties, carefully preparing soil, strengthening field management, and doing a good job in the prevention and control of diseases, pests and weeds.
