人粪尿是富含氮素的速效有机肥,肥效良好,果蔬栽培应用广泛,有显著的增产效果,但发酵方法不当可使氮素损失40%以上且污染无公害栽培的大气环境。科学的发酵方法是保证肥效和无公害生产的首要技术。1.新鲜的人粪尿放入发酵池,按3%的比例加入优质的过磷酸钙和少量的硫酸亚铁(每10 Human excrement is a fast-acting organic fertilizer rich in nitrogen, with good fertilizer effect. It is widely used in fruit and vegetable cultivation and has obvious yield-increasing effect. However, improper fermentation method can cause nitrogen loss by more than 40% and pollute the air environment of pollution-free cultivation. Scientific fermentation method is to ensure fertilizer efficiency and pollution-free production of the first technology. 1. Fresh human excrement into the fermentation tank, by 3% of the proportion of high-quality superphosphate and a small amount of ferrous sulfate (10
