用科学的方法积存农家肥,不仅可以有效地防止肥分挥发流失,还能成倍地提高其肥效。方法是:1 在人粪尿中加过磷酸钙 每100kg的人粪尿中加入5kg的过磷酸钙,搅拌均匀,存放5～10天。经化学反应,能使人粪尿中易发挥的碳酸铵转化成性质稳定的磷酸铵,从而防止了氮素的挥发流失,增加了人粪尿中的磷元素,提高了肥料的质量,以磷保氮。2 在人粪尿中加盐 每100kg的人粪 The scientific method of storing farm manure, not only can effectively prevent the volatile loss of fertilizer, but also exponentially improve its efficiency. Method is: 1 in human waste add calcium superphosphate per 100kg of human excrement by adding 5kg of superphosphate, stir, store 5 to 10 days. The chemical reaction can make the human excrement easily play ammonium carbonate into stable ammonium phosphate, thus preventing the loss of nitrogen volatilization, increasing the phosphorus in human excrement and improve the quality of fertilizer to phosphorus Nitrogen. 2 Add salt to human waste for every 100 kg of human excrement
