妙用人粪尿养鱼有六种方法,这是提高养鱼池内肥效,增产增收的一项技术措施。现简要介绍如下: 一是人粪尿内添加过磷酸钙。在每50公斤人粪尿里加入25公斤过磷酸钙,搅拌均匀,存放5～7天后使用。该法能使人粪尿中极易挥发的碳酸铵转化成稳定的磷酸铵,从而防止氮的流失,增加人粪尿中的磷元素,以磷保氮,放入池中可以提高肥效。 Magical use of manure and urine there are six ways to fish, which is to improve the efficiency of fish ponds, increase production and income of a technical measure. Now briefly introduced as follows: First, human urine add superphosphate. Add 25 kg of superphosphate per 50 kg of human waste, mix well and store for 5 to 7 days before use. The method can make human excrement easily volatile ammonium carbonate into stable ammonium phosphate, thus preventing the loss of nitrogen, increase the phosphorus in human excrement, phosphorus nitrogen, into the pool can improve fertilizer efficiency.
