摘　　要：以玉米及小麦秸秆为原料,添加粗纤维降解菌进行堆肥试验,30天连续分点采样,测定堆肥发酵过程中堆温、微生物组成、酶活性等的动态变化.结果表明,外源接种粗纤维降解菌可使堆体温度快速上升,且维持较长时间高温状态.在好氧堆肥中接种外源菌剂可以加快堆肥中有机质分解和转化,促进腐熟.Using corn and wheat straw as raw materials,adding crude fiber degrading bacteria to compost test,30 days of continuous sampling,to detect the change of temperature,microbial quantity,enzyme activity and so on during the composting process.The results showed that microbial agent could increase the tempera ture of the reactor and maintain the temperature for a period of time.Inoculation of exogenous bacteria in aer obic compost can accelerate the decomposition and transformation of organic matter in compost and promote ripening.
