摘 要:【目的】研究腐熟剂对鸡粪堆肥过程中堆料理化性质的影响,为畜禽粪便的工厂化处理提供参考。【方法】以取自郑州某养鸡场的鸡粪为供试材料,设计腐熟剂组(堆肥中添加了腐熟剂,其活菌数为2×1010 CFU/g)和正常堆肥发酵组(对照组,未添加腐熟剂)2个处理,测定发酵过程(0~40d)中2个处理鸡粪堆肥的温度、含水率、pH值、C/N和NH+4-N含量,并采用种子发芽指数对堆肥腐熟的毒害性进行评估,然后对发酵结束后2个处理鸡粪堆肥的养分含量进行测定。【结果】腐熟剂组鸡粪堆肥升温速度快,高温维持时间长;水分蒸发快,腐熟后的鸡粪含水率明显下降;发酵结束时,堆肥pH值维持在有利于微生物发酵的弱碱性环境。在发酵过程中,腐熟剂组的C/N在第20天时已小于20,达到腐熟。在发酵第35天时,腐熟剂组种子发芽指数达到80%,明显高于对照组。发酵结束时,腐熟剂组的堆肥臭味减轻,养分含量高于对照组。【结论】利用腐熟剂可以提高鸡粪堆肥发酵效率,减少堆肥养分的流失及对环境的污染。[Obiective] This study investigated the effects of decomposition agents on physicochemical properties of materials during chicken manure compost. [Methed] Two treatments, decomposing inocu- lums group (decomposing microbial inoculums with a viable count of 2× 1010 CFU/g were added) and nor- mal decomposing group (control group), were allocated in the experiment. Temperature, moisture content, pH value,C/N ratio and ammoniated nitrogen content of chicken manure compost were determined during the composting processing. The seed germination index was used to assess compost maturity toxicity. Sub- sequently,the nutrient contents of each group were measured after composting. [Result] The temperature of the decomposing inoculums group increased faster than that of the control,and maintained a high level. Besides, water evaporated faster in the decomposing inoculums group, and the manure water content signifi- cantly decreased after composting. Moreover, the chicken manure compost maintained a wea ronment,which was beneficial for the microbial decomposing inoculums group declined to 20 at at the end of the composting.
