Abstract: Soil is the environment on which crops depend for survival,the quality of soil directly affects the yield of crops,and the microorganisms in the soil also significantly affect the quality of farmland soil. In order to improve soil quality,it was necessary to clarify the impact of different soil management measures and environmental factors on the richness and diversity of microorganisms in farmland soil. This research reviewed the effects of soil management measures such as no-tillage,straw mulching,fertilizer application,intensive management,pesticides and heavy metal stress,and soil physical and chemical properties,growing seasons,vegetation coverage and other environmental factors on farmland soil microorganisms. Studies believed that no-tillage,straw mulching,fertilizer application,intensive management,vegetation coverage,etc. had a positive impact on soil microbial activity and diversity;different growth seasons of microbes had different effects on them,and microbial growth and metabolism in summer were more vigorous than that in winter;excessive application of pesticides and heavy metal stress would have toxic effects on soil microorganisms and adversely affect farmland soil health.

Key words: Farming measures, Farmland management, Soil microorganisms, Microbial community
