Evaluation method for agricultural non-point source pollution of organic waste resources and application

Abstract

The invention provides an evaluation method of agricultural non-point source pollution of organic waste resources and application. According to the evaluation method, the agricultural non-point sourcepollution risk of organic waste resources can be systematically evaluated; the method is further applied to an area for preventing and treating agricultural non-point source pollution, the total amount of organic nutrients in agricultural organic waste is checked, resources are converted and then scientifically benchmarked to the essential requirement for improving the soil fertility of degradedsoil, accurate matching of the regional organic nutrients and the land bearing capacity is achieved, and therefore the regional nutrient comprehensive management purpose of farmland chemical fertilizer is scientifically achieved. Further, the problem of resource waste caused by discarding of a large number of nutrient resources in the agricultural organic wastes as wastes is solved in a targeted manner; the current situation of environmental pollution caused by random discarding of organic waste is improved, the industrial chain and the value chain of regional agricultural organic waste resource cyclic utilization are further guided to be improved, and the purposes of production cleanness, utilization safety, water and soil co-governance and agricultural sustainable development are achieved.

Description

technical field [0001] The invention relates to the technical field of ecological environment management, and more specifically, relates to an evaluation method and application of agricultural non-point source pollution of organic waste resources. 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 year, and the co...

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to provide an evaluation method and application of agricultural non-point source pollution of organic waste resources, which can systematically evaluate agricultural non-point source pollution caused by organic waste resources, and then solve the problem of agricultural organic pollution in a targeted manner. A large number of nutrient resources in waste are discarded as waste, causing resource waste, improving the current situation of environmental pollution caused by random discarding of organic waste, and further guiding the industrial chain and value chain improvement of regional agricultural organic waste recycling and utilization. To achieve the goals of clean production, safe utilization, water and soil governance, and sustainable agricultural development
