摘　　要：为了探讨微生物菌剂对小麦秸秆和尿素静态堆腐过程的影响机制,研究了在静态通气条件下,微生物菌剂对堆腐过程温度和水解酶活性的影响。结果表明,G+J(添加葡萄糖活化的微生物菌剂)、J(微生物菌剂)和CK(不加微生物菌剂)处理的最高温度分别为66.0℃、67.1℃和59.5℃,整个堆腐过程温度高于50℃的时间为:G+J(240 h)>J(120 h)>CK(96 h)。G+J处理的纤维素酶活性峰值出现在第9 d,达到334.37 mg/(g.d),J和CK酶活性峰值较G+J滞后3 d和6d出现,酶活性峰值分别为271.59 mg/(g.d)和236.67 mg/(g.d);G+J处理蔗糖酶活性峰值是CK处理的2.53倍,J处理蔗糖酶活性是CK处理的2.33倍;随着堆腐时间的延长,23d后各处理脲酶活性均小于20.00mg/(g.d)。相关性分析表明,3个处理的纤维素酶活性与温度负相关,但是不显著(P>0.05);G+J处理的蔗糖酶活性与温度呈极显著负相关,J处理的蔗糖酶活性与温度呈显著性负相关;3个处理的脲酶活性与温度均达到显著或极显著负相关(P<0.05,P<0.01)。可见,复合微生物菌剂可以改变腐解过程中温度与水解酶活性。The objective of the study was to research the potential mechanism of microbial inoculants on the static agricultural waste composting process.An experiment was conducted with mixed materials of wheat straw and urea to study the changes of temperature and activities of hydrolase during composting at static state.The results revealed that the highest temperature of three treatments,under the conditions of adding microbial inoculants which was activated by glucose(G+J),adding microbial inoculants(J)and no mic...
