摘　　要：土壤中磷资源丰富,然而约95%的磷无法被植物直接利用。溶磷微生物是一类可以通过自身繁殖和代谢将土壤中无效态的磷转化为植物可以直接吸收利用的有效态磷的功能微生物。该研究综述了土壤中溶磷微生物的种类、分布特征,溶磷机理及其促生作用等。同时,对溶磷微生物资源在农业中的应用进行展望,旨在溶磷微生物资源收集、开发应用以及建立资源节约、环境友好的农业生产方式提供参考依据。Soil has a large stock of phosphorus,but about 95%of it is not directly available to plants.Phosphorus solubilizing microorganisms can convert ineffective phosphorus into effective phosphorus,increase the content of effective phosphorus in soil,and play an important role in promoting plant growth.In-depth research on phosphorus solubilizing microorganisms can help to develop resourcesaving and environment-friendly agriculture,and its application prospects are also very broad.In this paper,we review the species and distribution of phosphorus solubilizing microorganisms,their phosphorus solubilizing mechanisms and biomass promotion effects,and their future applications to provide a reference for future research directions of phosphorus solubilizing microorganisms.
