摘　　要：研究不同耕作方式下土壤微生物群落,对揭示耕作方式对土壤质量的影响及机制具有重要的指导意义。本文综述了保护性耕作对农田土壤微生物特性及参与土壤碳氮循环的微生物功能基因的影响,并详述了土壤微生物的驱动机制;指出了不同耕作处理对微生物影响效果不同,保护性耕作有助于维持土壤微生物多样性及活性,保持土壤生态系统的稳定性。同时,文章还分析了目前研究中存在的问题,并对今后研究方向进行了展望。Soil microbial community plays an important role in revealing the effects of tillage on soil quality and its mechanisms.This paper reviews the effects of conservation tillage on soil microbial characteristics,microbial functional genes involved in soil nutrient cycling,and the driving mechanism of soil microorganisms.It is pointed out that different tillage treatments have different effects on microorganisms,and conservation tillage helps to maintain the diversity and activity of soil microorganisms and maintain the stability of the system.The paper also points out the existing problems in the current research and makes an outlook on the future research direction.
