由于工业生产的“三废”对农业生态环境的污染和农业生产中片面追求产量,盲目过量施用化肥和喷施农药的现象相当普遍。致使化肥、农药利用率低下,导致农业生态环境和农产品遭受不同程度的污染。据调查,我国遭受工业“三废”危害的农田面积达1000万公倾,每年使用农药约20多万t。每年生产不符合食品卫生标准的农畜产品 Due to the pollution of agro-ecological environment caused by the “three wastes” of industrial production and the one-sided pursuit of production in agricultural production, it is quite common that excessive application of chemical fertilizers blindly and pesticide spraying is widespread. As a result, the utilization rate of fertilizers and pesticides is low, resulting in the pollution of agricultural ecological environment and agricultural products to varying degrees. According to the survey, the area of ​​farmland endangered by “three wastes” in our country has reached 10 million hectares, and about 200,000 tons of pesticides are used annually. Annual production does not meet the food hygiene standards of agricultural and livestock products
