[Objective ] The effects of composite microbial inoculant on aerobic composting cattle dung were studied to provide theoretical guidance of disposing high-fiber waste such as cattle dung effectively. [ Method]The experiments were set up three treatments for aerobic compost text with cattle dung including no-inoculant( C) , inoculantion of microbial group with 0. 5 g/kg (T1 ) , inoculantion of microbial group with 1 g/kg (T2). 4 indicators such as temperature, water content, pH and C/N ratio were investigated. [ Result]Compared to the control group, the two composts with microbial inoculant could warm up more quickly and hold a longer lime with high temperature( >50 ℃). Meanwhile, their water content was lower, both their pH and nitrogen content were higher,and their C/N ratio was all less than 20. [ Conclusion] By adding the composite microhial inoculant, it could effectively accelerate the composting process and shorten the composting period.%[目的]研究微生物接种剂对牛粪好氧堆肥的影响,为有效处理鲜牛粪等高纤维废弃物提供理论指导.[方法]以牛粪为堆肥原料进行好氧堆肥试验.试验设3个处理:不添加接种菌剂(C)、添加接种量为0.5 g/kg的复合微生物菌剂(T1)、添加接种量为1 g/kg的复合微生物菌剂(T2).对堆肥过程中的温度、含水率、pH和C/N比4个指标进行跟踪测定.[结果]与对照相比,添加微生物菌剂的2个堆体升温较快且高温(＞50℃)维持时间较久,含水量较低,pH较高,全氮含量较高,C/N比均降至20以下.[结论]添加微生物菌剂可有效加快堆肥进程,缩短堆肥周期.
