Prevention and treatment Treatment method for agricultural non-point source pollution in water-soil co-treatment area

Abstract

The invention provides a prevention and treatment method for agricultural non-point source pollution in a water and soil co-treatment area. Agricultural non-point source pollution prevention and treatment in a water and soil co-treatment area are achieved. By checking the total amount of organic nutrients of agricultural organic wastes, the agricultural organic wastes are scientifically benchmarked into the essential demand of improving the soil fertility of the degraded soil after resource conversion, and the regional organic nutrients and the land bearing capacity are accurately matched, sothat the regional nutrient comprehensive management purpose of scientifically reducing the farmland chemical fertilizer consumption is achieved; agricultural non-point source pollution caused by nitrogen and phosphorus loss due to unreasonable utilization of agricultural organic wastes and farmland nitrogen and phosphorus loss due to excessive use of chemical fertilizers is creatively controlled from the source; the problem that a large number of nutrient resources in agricultural organic waste are discarded as waste to cause resource waste is solved. The current situation of environmental pollution caused by random discarding of organic wastes is improved, the environmental pollution caused by excessive use of chemical fertilizers is effectively controlled, the degradation risk of the cultivated land quality is reduced, and the method has important significance for agricultural non-point source pollution control and ecological environment treatment.

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
