摘要: 土壤微生物对土壤变化的反应极为敏感,秸秆还田对土壤微生物产生的影响对维持稻田系统氮素循环极其重要。秸秆还田通过对土壤微生态环境的改变影响氮素在土壤中的生物化学转化过程,进而影响水稻生产的氮素管理策略。在查阅近年来发表的相关研究论文基础上,对秸秆还田下水稻土壤氮素转化过程中相关功能微生物的作用以及关键功能基因驱动机制等研究进行综述,以期厘清秸秆还田后稻田生态系统中微生物介导的氮素循环转化机制,为稻田科学施用氮肥提供理论依据。

Abstract: The response of soil microorganisms to soil changes is extremely sensitive, and the impact of straw returning on soil microbial community is important for the soil nitrogen cycling maintainance in paddy field systems. Straw incorporation to soils influences the biochemical transformation of soil nitrogen by changing the soil microecological environment. The nitrogen management strategy in rice production is closely related to these changes in soil nitrogen transformation. Based on the latest published research papers, this study reviewed the soil nitrogen transformation processes, the functions of related functional microbes, and the driving mechanisms of the key functional genes in paddy field soil with straw incorporation. It would help to understand the microbial mechanism of soil nitrogen cycling in paddy field soils with straw incorporation, and provide theoretical basis for the scientific application of nitrogen fertilizer in paddy field systems.

Key words: straw returning, paddy field, nitrogen cycle, soil microorganisms, functional genes
