Synergy of pollution reduction and carbon reduction! How to control agricultural non-point source pollution?
Recently, the Ministry of Ecology and Environment, the National Development and Reform Commission, the Ministry of Industry, and Information Technology, the Ministry of Housing and Urban-Rural Development, the Ministry of Transport, the Ministry of Agriculture and Rural Affairs, and the Energy Administration jointly issued the "Implementation Plan for Pollution Reduction and Carbon Reduction Synergy" (hereinafter referred to as the "Implementation Plan").
The "Implementation Plan" proposes that by 2025, the work pattern of coordinated promotion of pollution reduction and carbon reduction will be basically formed; the structural optimization and adjustment of key areas and key areas and green and low-carbon development will achieve obvious results; a batch of typical experience that can be replicated and promoted will be formed. ; The synergy of pollution reduction and carbon reduction has been effectively improved. By 2030, the synergistic ability of pollution reduction and carbon reduction will be significantly improved, helping to achieve the goal of carbon peaking; the coordinated promotion of carbon peaking and air quality improvement in key areas of air pollution prevention and control will achieve remarkable results; water, soil, solid waste and other pollution prevention and control areas. level has increased significantly.
In the field of agriculture, one of the key areas, the "Implementation Plan" clearly proposes to promote the green production mode of agriculture, and coordinate the promotion of energy conservation, emission reduction and pollution control in planting, animal husbandry and fishery. In-depth implementation of the action of reducing the number of chemical fertilizers and pesticides and increasing the efficiency, strengthen the prevention and control of non-point source pollution in the planting industry, optimize the management of water irrigation in paddy fields, and improve the efficiency of nitrogen fertilizer utilization. Improve the comprehensive utilization level of straw and strengthen the management and control of straw incineration. Improve the level of resource utilization of livestock and poultry manure.
We know that chemical fertilizers and pesticides, crop straws and livestock and poultry manure are the three key points of agricultural non-point source pollution. Over the years, relevant state departments have achieved remarkable results in their governance, and agricultural non-point source pollution has been effectively curbed.
Continued reduction of chemical fertilizers and pesticides, achieving negative growth for 4 consecutive years
Since 2015, the Ministry of Agriculture and Rural Affairs has carried out a zero-growth campaign for the use of chemical fertilizers and pesticides, and vigorously promoted the technology model of saving fertilizers and pesticides. In recent years, the use of chemical fertilizers and pesticides has been continuously reduced, achieving zero growth ahead of schedule and achieving negative growth for four consecutive years.
The "14th Five-Year Plan for Promoting Agricultural and Rural Modernization" also clearly proposes to continue to promote the reduction and efficiency of chemical fertilizers and pesticides, carry out in-depth soil testing and formula fertilization, continue to optimize the structure of fertilizer inputs, increase the use of organic fertilizers, and promote efficient fertilizer application technology. Actively and steadily promote the elimination of high-toxicity and high-risk pesticides, accelerate the promotion of low-toxicity and low-residue pesticides and high-efficiency large and medium-sized plant protection machinery, and integrate the application of green pest control technologies according to local conditions. Promote the reduction of the use of veterinary antibiotics, and standardize the production and use of feed and feed additives. By 2025, the utilization rate of chemical fertilizers and pesticides for major crops will reach more than 43%.
The comprehensive utilization rate of straw in China exceeds 86%
As we all know, promoting the comprehensive utilization of crop straws is an important measure to improve the quality of cultivated land, improve the agricultural and rural ecological environment, and accelerate the green and low-carbon development of agriculture. During the "Thirteenth Five-Year Plan" period, the central government allocated a total of 8.65 billion yuan to implement the comprehensive utilization of straw, supporting 674 counties to improve the utilization of straw, and promote the comprehensive utilization rate of straw nationwide to reach 86.7%.
In 2022, the Ministry of Agriculture and Rural Affairs will continue to vigorously promote the comprehensive utilization of straw, and build 300 key counties for straw utilization and 600 exhibition bases for comprehensive utilization of straw throughout the year, and the comprehensive utilization rate of straw across the country will remain above 86%. The straw collection, storage and transportation system has been continuously improved, the main body of the straw utilization market has been further expanded, the market operation mechanism has been continuously improved, the structure of straw industrial utilization has been further optimized, the scale of straw forage conversion and clean energy utilization has been continuously expanded, and the utilization of straw as a base material and raw material will continue. keep expanding.
The utilization rate of livestock and poultry manure resources has exceeded 75%
It is understood that the annual production of livestock and poultry manure in the country is about 3 billion tons, and the resource utilization of livestock and poultry manure is the fundamental way to solve the pollution problem of livestock and poultry breeding, the fundamental way to promote the combined development of planting and breeding, and the way to improve soil fertility. powerful measures. During the "Thirteenth Five-Year Plan" period, the central government allocated a total of 29.6 billion yuan to implement the county-wide system to promote the resource utilization of livestock and poultry manure, and supported 723 counties to improve the capacity of manure utilization. The comprehensive utilization rate of livestock and poultry manure resources nationwide exceeded 75%.
The "14th Five-Year Plan for Promoting the Modernization of Agriculture and Rural Areas" clearly proposes to support the development of green and circular agriculture with organic integration of planting and breeding, continue to carry out the resource utilization of livestock and poultry manure, strengthen the construction of manure treatment facilities in large-scale farms, and promote the return of manure to the field. use.
Promoting the resource utilization of livestock and poultry manure is not only of great significance to the development of green and circular agriculture that combines planting and breeding, but also has a great role in improving the living environment in rural areas and building beautiful villages.
