| 摘 要： | 以不同预处理的猪粪为饵料,在温度2 0℃、湿度70 %的培养箱里培养赤子爱胜蚓。对蚯蚓处理前的饵料和蚯蚓处理后蚓粪的C/N比、NH+4 -N和NO- 3-N的含量变化进行了测试对比。结果表明:与饵料相比,蚓粪的C/N比、NH+4 -N下降,NO- 3-N上升。

| Abstract: | Taking different pre-disposed pig manure as food,Eisenia fetida were cultured in incubator at temperature of 20 ℃ and humidity of 70%. The contents of the ratio of C/N, pH value, NH +_4-N and NO -_3-N in the pre-disposed pig manure and vemicast were tested and compared. The result showed that the C/N ratio and NH +_4-N decreased and NO -_3-N increased evidently after Eisenia fetida vemicomposting. |
