doi:10.11924/j.issn.1000-6850.casb2022-0111

Abstract

Abstract:

In order to deeply understand the straw aerobic composting technology and further explore the related mechanism of microbial degradation of straw, and to improve the comprehensive utilization rate of straw resources, this study summarized the aerobic composting degradation process of crop straw and its influencing factors, and summed up three types of crop-straw degrading bacteria and the community succession characteristics of bacteria in the composting process. The degradation effect of the external inoculants with high enzymatic activity in the process of straw composting was analyzed. On this basis, the authors believed that although there were many factors affecting the composting process, aerobic composting of crop straw still had broad application prospects. In addition, current research on the degradation and mechanism of key microorganisms in the composting process is still limited. In future research work on aerobic composting of straw, the research on the functional microbial degradation mechanism of straw composting should be enhanced.

Key words: crop straw, aerobic composting, degrading bacteria, community succession, external inoculants
