人尿中的氮素含量较高。一般1000斤人尿含5斤氮素,相当于25斤硫铵、11斤尿素、28斤碳铵的肥效。健康人尿,不含病菌,很易腐熟,可用生尿直接施用,和化肥一样效果又快又好。因此,每户积存的人尿,够一挑时,就挑到地里,按顺序泼浇,每亩按1000～2000斤施用。这样一秋冬,即使人口最少的家,也可浇3亩地。这3亩地明年便可不用施氮肥了。 Nitrogen in human urine is higher. General 1000 kg of human urine containing 5 kg of nitrogen, equivalent to 25 kg ammonium sulfate, 11 kg of urea, 28 kg of ammonium bicarbonate fertilizer. Healthy urine, bacteria-free, very perishable, available urine direct application, and fast and good as fertilizer. Therefore, the accumulation of urine per household, enough to pick, pick the ground, poured in order, according to 1000 ~ 2000 kg per mu application. Such a winter, even the most populous home, but also can pour 3 acres of land. This 3 acres of land next year can be nitrogen fertilizer.
