随着我国养猪业的迅速发展,规模化养殖已成为我国农村面源污染的主要来源。猪粪便排放量超过了周围土地对其消纳能力,这不仅对环境造成污染,同时也将严重制约养猪行业的发展。试验通过测量猪的排粪、尿量及粪尿中氮、磷含量,调查一定种植模式下土地对氮、磷的消纳能力,确定规模化猪场粪污排放与所需消纳土地的参数,可为各地产业布局及养殖规模的科学规划提供参考依据。
With the rapid development of pig industry in our country, large-scale farming has become the main source of non-point source pollution in rural areas of our country. Pig manure emissions exceed the capacity of the surrounding land to absorb it, which not only pollute the environment, but also will seriously restrict the development of the pig industry. The experiment measured the excretion and urine volume of pigs and the contents of nitrogen and phosphorus in excrement and urine, and investigated the capacity of land to absorb nitrogen and phosphorus under certain planting patterns, and determined the parameters of excrement discharge and land requisition , Can provide a reference for the scientific planning of the industrial layout and breeding scale.
