摘　　要：[Objective] In order to study the influence of bacteria and accessories of chicken manure compost.[Method] The experiment was conducted to investigate the changes of temperature,the quantification of Escherichia coli and the odor during chicken manure compost by adding sawdust,rice husk,yeast and lactic acid bacteria respectively.[Result] The results showed that：（1） The yeast group reached the highest fermentation temperature 67.6 ℃,which was 6.9 ℃ higher than that of lactic acid bacteria group,and the fermentation time of yeast group kept over 55 ℃for 16 days,which was 5 days longer than that of lactic acid bacteria group,both of which were better than that of control group（55.9 ℃,5 days）;（2）The highest fermentation temperature of sawdust group was 2.2 ℃ higher than that of rice husk group,and the fermentation time of sawdust group kept over 55 ℃ was 3 days longer than that of rice husk group;（3） The quantification of E.coli reduced from10^5 to 10^2per gram in both of the yeast group and the lactic acid bacteria group.The odor of the yeast group and the lactic acid bacteria group disappeared in the seventh day and the eighth day respectively.[Conclusion] The results showed that the adding of yeast and sawdust was the best condition for chicken manure composting in this experiment.[目的]探讨菌种和辅料对鸡粪堆肥效果的影响。[方法]试验以鸡粪和木屑稻壳为发酵原料,分别添加酵母菌和乳酸菌,研究菌种和辅料对鸡粪发酵过程中温度大肠杆菌群数和臭味的变化。[结果]1添加酵母菌组的发酵最高温度达到67.6℃,比乳酸菌组高6.9℃,且酵母组发酵温度在5℃以上持续了16 d,比乳酸菌组多5 d,两组均高于对照组(59℃和5 d);2添加木屑组的发酵最高温度比稻壳组高2.2℃,5℃以上的持续时间多3天;3酵母菌组、乳酸菌组的粪中大肠杆菌的数量由105个/g德下降到102个/g,其粪臭味分别在第7天和第8天消失。[结论]在该试验条件下,在鸡粪中添加酵母菌和木屑的堆肥发酵效果是最好的。
