把畜尿收集起来作为肥料施用,不仅可以减少家畜养殖中的粪尿污染,而且可以广辟肥源,促进农业增产。据测算,1头猪从小养到8个月,可排泄1200～1300kg尿液,相当于纯氮(N)3.6～3.9kg、磷(P2O5)1.44～1.56kg、钾(K2O)12～13kg。畜尿的成分比较简单,全部是水溶性物质,主要有尿素、尿酸、马尿酸以及 The collection of livestock urine as a fertilizer application, not only can reduce the excrement and urine pollution in livestock breeding, but also to broaden sources of fertilizer and promote agricultural production. It is estimated that a pig from raising a small to 8 months, can excrete 1200 ~ 1300kg urine, equivalent to pure nitrogen (N) 3.6 ~ 3.9kg, phosphorus (P2O5) 1.44 ~ 1.56kg, potassium (K2O) 12 ~ 13kg. Animal urine composition is relatively simple, all water-soluble substances, mainly urea, uric acid, hippuric acid and
