Abstract Simple cropping（including continuous cropping and simple rotation） and excessive
water and fertilizer input are 2 common phenomenon in Chinese protected vegetable cultivation．This
phenomenon results in the problems of soil biological obstacles：as reduction of microbial diversity of
protected vegetable soil，increasing of microbial pathogens, and damage of plant-parasitic nematodes，
etc．Soil microbial obstacles have greatly threatened the sustainable utilization of soils in protected
vegetable production systems in China．Soil microbe is one of the important factors that influence the
plant growth，evolutionary process and productivity．Currently studies on vegetable soil microbial
obstacles in protected cropping system have made significant progress．However，most of the study
efforts are mainly focused on the general changes of soil microbial communities responding to human
management，and thorough studies on change of soil ecological service function are needed to carry
out. Therefore，this paper reviewed the internal and external studies on soil microbial obstacles，
summarized the ecological effect of soil microbe-crop interaction and analyzed the key point for studying
vegetable soil microbial obstacles in protected cropping systems．Besides，this paper briefly introduced
the major ecological measures adopted in China to control these obstacles．It also provided suggestions
for revealing potential causes of these obstacles in the future .
