一、人粪尿。人粪尿是农田的大宗肥料,它是粗肥中的细肥,缓效肥料中的“速效肥料”。由于其养分全面,肥效较快,稍经转化,作物即可吸收利用,所以,其多作追肥,特别是生长季节较短的蔬菜类施用较多。人粪尿中含有大量病菌和寄生虫虫卵,直接施用会污染蔬菜,使蔬菜感染病虫,危及人畜健康。所以人粪尿需经简单的无害化处理,杀死病菌和虫卵,变成“无害肥料”。人粪尿无害化的主要方法有: 1.发酵池密闭沤制。利用这种方法沤制,伤寒、霍乱、痢疾等传染病菌,30小时便可死亡。就是生命力很强的血吸虫虫卵,在密闭发酵池中,气温 First, human excrement. Human excrement is the bulk of farmland fertilizer, which is fat in coarse fat, slow-acting fertilizer in the “quick-acting fertilizer.” Because of its comprehensive nutrients, fertilizer faster, a little transformed, the crop can be absorbed, so it is more for topdressing, especially in the growing season, shorter application of vegetables. Human excrement contains a large number of bacteria and parasite eggs, direct application will contaminate vegetables, vegetables, pests and diseases, endangering the health of humans and animals. Therefore, human excrement need simple harmless treatment, killing bacteria and eggs, into a “harmless fertilizer.” Human urine harmless of the main methods are: 1. Fermentation tank closed system. In this way, infectious diseases such as typhoid, cholera and dysentery can be killed within 30 hours. Is a very strong schistosomula eggs, in a sealed fermentation tank, the temperature
