| 摘要 |
农作物秸秆还田是提高秸秆综合利用率、实现土壤养分归还及可持续利用的有效措施之一,已经成为持续农业和生态保护的重要措施。但秸秆含有大量的纤维素、半纤维素、木质素等大分子成分,在土壤中分解缓慢,因此筛选秸秆降解菌来加速秸秆腐殖进程成为秸秆降解的关键。当前秸杆降解菌的筛选研究有很多,但抗逆境秸杆降解菌的筛选和应用研究较少。我国地域辽阔,不同地区的气候复杂多样,对于不同地区的最适高效降解菌的应用还需进一步研究。本文综述了秸秆微生物降解菌种类、逆境条件下秸秆降解菌的应用研究进展等,以期为我国逆境条件下秸秆还田、节本、保肥增效提供有效依据。

| Abstract |
Crop straw returning is one of the effective measures to improve the comprehensive utiliza- tion rate of straw, achieve soil nutrient return and sustainable utilization, and has become an important measure for sustainable agriculture and ecological protection. However, straw contains a large number of macromolecular components such as cellulose, hemicellulose, and lignin, which are slowly decomposed into soil. Therefore, screening straw-degrading bacteria to accelerate the process of straw humification has become the key to straw degradation. At present, there are many studies on the screening of cellulose-de- grading bacteria, but there are few studies on the screening and application of stress-resistant cellulose- degrading bacteria. China has a vast territory, and the climate in different regions is complex and di- verse. The application of the most efficient degrading bacteria in different regions needs further study. In this paper, the types of straw microbial degrading bacteria and the application research progress of straw degrading bacteria under adversity conditions were reviewed, in order to provide an effective basis for straw returning, cost saving, fertilizer conservation and efficiency improvement under adversity conditions in China.
