Abstract: An experiment was conducted with mixed materials of chicken excrement and wheat straw to study the changes of temperature and oxidization and reduction enzyme during rottening processing in a static state. Results showed that temperatures of different positions of the treatments of adding microorganism fungus were higher than those of CK, and the temperatures rose more quickly than those of CK. The temperature of the materials adding microorganism fungus above 50℃ lasted for 14～20 d, and that of CK was 7.5～10 d. The activity of enzyme of H₂O₂ in the materials adding microorganism fungus was higher than that of CK during 1～26 d, and dehydrogenase activity was higher than that of CK in the middle period of the composting. All of them indicated that the microorganism fungus could promote the decomposition. During 5～28 d the materials of adding microorganism fungus, the polyphenol oxidized activity was higher than that of CK, and the E₄/E₆ values of materials of adding microorganism fungus were 1.57～1.68, and the E₄/E₆ values of CK were 2.16～2.41 after 30 d, which indicated that microorganism fungus could promote processing of humus.
