| Abstract: |
| 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. |
