Phosphorus，one of the essential nutrients for plant growth，mainly exists in soil in the form of insoluble phosphide，which is difficult to be directly absorbed by plants.Phosphate-solubilizing microorganisms，as an important part of soil phosphorus cycle，can transform insoluble phosphorus into soluble phosphorus which can be absorbed by plants through acidification and enzymatic hydrolysis，thus increasing the utilization rate of soil phosphorus by plants.Therefore，they are generally considered as important beneficial microorganisms that can promote plant growth.In this review，the species，ecological distribution characteristics，detection of phosphorus solubilizing ability，influencing factors of phosphorus solubilization，phosphorus solubilizing mechanism and application status of phosphate-solubilizing microorganisms were summarized，and the research prospects based on the problems existing in the current application of phosphate-solubilizing microorganisms was discussed.
