摘　　要：采用药用价值高、吞食量大的威廉环毛蚓进行牛粪消解试验,以期在资源再生利用的同时获得更高的经济效益。通过考察pH、温度、湿度和接种密度等4个环境因子对蚯蚓日增重倍数和基质降解速率的影响,研究威廉环毛蚓消解牛粪的最优条件。结果表明:威廉环毛蚓消解牛粪最佳pH为7.0—8.5,温度为20—25℃,湿度为60%—70%,最佳接种密度为蚯蚓与基质质量比1/40。In order to obtain higher economic benefits in the utilization of resource recycling,the cow manure digestion test was conducted by Pheretima guillelmi,which had high medical value and large amount of swallowed.Through investigation of pH,temperature,humidity and inoculation density on the earthworm daily weight increment and substrate degradation rate,the optimal conditions for cow manure digestion of Pheretima guillelmi were studied.The results showed that the optimal pH,temperature,humidity and inoculation density were 7.0—8.5,20—25 ℃,60%—70%,earthworm and substrate mass ratio 1 /40,respectively for cow manure digestion of Pheretima guillelmi.
