Phosphorus(P)is an indispensable element for plant growth.Although the total P content in soil is rich,the available P content,which can be directly absorbed and utilized by plants,is very low.Traditional methods to increase crop yield in phosphorus deficient is by applying P fertilizer.However,the phosphorus applied to the soil is not only easily to be fixed by soil,but also easily transformed into organic P that is difficult for plants to absorb directly,so as to reduce the P utilization rate by plants and cause environmental pollution.Phosphorus solubilizing bacteria can transform insoluble P in soil into available P that can be directly absorbed by plants,and improve the absorption and utilization rate of P by plants.The action mechanism of phosphorus solubilizing bacteria is complex,and existing various kinds of bacteria and existing many influencing factors.This paper mainly reviewed the research progress of phosphorus solubilizing mechanism of phosphorus solubilizing bacteria and summarized the application of phosphorus-solubating bacteria in rice production.It provided a theoretical basis for improving the utilization efficiency of insoluble phosphorus in paddy soil.
