中文摘要：
为了解小麦秸秆堆肥过程中的生物化学特征，进行了高温好氧堆肥试验。结果表明，添加复合微生物腐解菌剂处理较不添加复合微生物腐解菌剂（CK）升温快，温度高，高温持续时间长；堆腐第2d添加菌剂处理堆体温度上升到50℃以上，第3d达到最高温度67．1℃，50℃以上持续6d；CK堆腐第3d达到50℃，第4d达最高温度59．5℃，50℃以上持续5d。堆腐第9d添加菌剂处理E4／E6僮达高峰值3．419，CK的达高峰值4．085，堆腐第23d后添加菌剂处理的胡敏酸E4／E6值为1．512—1．709，而CK处理的E4／E6值为1．649—2．060，堆腐过程添加菌剂处理的E4／E6值一直低于CK，表明添加菌剂能促进腐殖质的缩合和芳构化。堆肥腐熟后pH值较堆制前有所提高，添加菌剂处理的pH值相对较低，变化幅度较小。加入微生物菌剂处理的电导率（EC）值较高，且在持续高温阶段高于后熟阶段。
英文摘要：
An experiment was conducted to study the biochemical characteristics of wheat straw during its composting at high-temperature and static state. There were two treatments in this experiment, one was with adding microorganism agent, and the other was without adding microorganism agent （CK）. The results indicated that the treatment of adding microorganism agent had faster temperature rising, higher temperature and longer high temperature duration than CK; The E4/E6 values increased in the initial stage but decreased thereafter, the E4/E6 values of materials of adding microorganism fungus were 1.512 - 1.709, and the E4/E6 values of materials of CK were 1.649 - 2.060 after 23 d, which indicated that microorganism fungus could promote processing humus; It has been discovered that pH values increased after composting while the rate of conductance decreased.
