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。
With different pretreatment of pig manure as bait, in the temperature 20 ℃, 70% humidity incubator Eichhornia crassipes. The changes of C / N ratio, NH + 4 -N and NO-3-N content of earthworms before treatment and earthworm treatment were compared. The results showed that the ratio of c / N, NH + 4 -N and NO-3-N of vermicompost increased compared with that of the diet.
