A method for preventing and controlling agricultural non-point source pollution in water and soil co-governance areas

Abstract

The invention provides a method for preventing and controlling agricultural non-point source pollution in a water and soil co-governance area. Aiming at the prevention and control of agricultural non-point source pollution in a water and soil co-governance area, through inventorying the total amount of organic nutrients in agricultural organic waste, scientific benchmarking to degradation after resource transformation In the essential demand of soil fertility improvement, realize the precise matching of regional organic nutrients and land carrying capacity, so as to scientifically reduce the amount of farmland chemical fertilizers for the purpose of regional nutrient comprehensive management; pioneering from the source to control the nitrogen and phosphorus caused by the unreasonable use of agricultural organic waste Agricultural non-point source pollution caused by the loss and excessive use of chemical fertilizers caused by the loss of nitrogen and phosphorus in farmland, solve the problem of resource waste caused by a large amount of nutrient resources in agricultural organic waste being discarded as waste, and improve the pollution caused by random discarding of organic waste It is of great significance for the control of agricultural non-point source pollution and the governance of the ecological environment to effectively control the environmental pollution caused by excessive use of chemical fertilizers and reduce the risk of degradation of cultivated land quality.

Description

technical field [0001] The invention relates to the technical field of ecological environment management, and more specifically relates to a method for preventing and controlling agricultural non-point source pollution in a water and soil joint governance area. Background technique [0002] With the rapid development of my country's agricultural production level and the continuous improvement of national living standards, as the main gathering place for grain production and meat and dairy farming in rural areas, the types and quantities of agricultural organic waste generated each year have increased sharply. According to reports: Straw and livestock and poultry manure account for the largest proportion of the waste, and they are also the two main sources of rural non-point source pollution, accounting for more than 70% of the total rural non-point source pollution. The latest statistics show that the amount of straw produced in rural areas is nearly 900 million tons every ye...

Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a method for the prevention and control of agricultural non-point source pollution in water and soil co-governance areas, which can solve the problem of waste of resources caused by a large amount of nutrient resources in agricultural organic waste being discarded as waste, and improve the pollution caused by organic waste. The current situation of environmental pollution caused by the random discarding of waste, and effectively control the environmental pollution caused by excessive use of chemical fertilizers, reduce the risk of arable land quality degradation, promote the improvement of arable land quality, reduce weight and reduce pesticides, and guide the industrial chain and value of regional agricultural organic waste resource recycling Chain improvement, to achieve the goals of clean production, safe utilization, input reduction, water and soil governance, and sustainable agricultural development
