As the stable and efficient development of tomato industry，the soil quality of the facility tomato problems are becoming more and more serious.In this experiment，the effects of microbial soil conditioner were used in the plot experiment.The soil nutrients，number of microorganisms，yield of tomato under different experimental treatments were analyzed.The results showed that the application of microbial soil conditioner significantly increased the yield and economic benefits of tomato，significantly reduced the soil bulk density and increased soil porosity； it also increased the nutrient content of the soil.Compared with the control treatment，soil pH，the contents of soil organic matter，nitrate nitrogen，ammonium nitrogen，available phosphorus and available potassium increased by 0.2%～4.6%，1.2%～5.1%，4.2%～11.8%，6.9%～23.8%，5.4%～7.9% and 3.1%～7.7%，respectively，with application of microbial soil conditioner.The number of soil bacteria and actinomycetes increased significantly，and the number of fungi decreased significantly.As a consequence，the application of soil remediation bacteria can not only increase crop yield，but also improve soil quality.
