对牛、羊粪高温堆制过程研究结果表明：全氮分别增加了5.11%、5.18%,全磷分别增加了10.79%、9.82%,全钾分别增加了142.11%、153.08%;堆肥完成时间一般以14 d为宜,超过则易造成硝态氮随水流失,肥效降低;该方法操作简单,成本低,易于推广。%A study of high temperature composting process of cattle and sheep dung showed that the total nitrogen increased by 5.11% and 5.18% respectively, total phosphorus increased by 10.79% and 9.82% respectively and total K increased by 142.11%a and 153.08% respectively. The compost completion time should be 14 days commonly and if the compost completion time is longer than this the nitrate nitrogen would loss with the water and fertilizer efficiency would decrease. The approach is characterized by simple operation, low cost and easy popularization.
