摘　　要：磷是植物生长发育所必需的营养元素之一。土壤中能被植物吸收利用的有效态无机磷很低，一般只占全磷量的2％～3％，大部分很难被作物吸收利用。针对有效磷缺乏、土壤潜在磷源丰富的现状，开发与利用解磷微生物，是土壤肥料与植物营养领域的研究热点。论述了解磷微生物的种类、分布、解磷机理、现状，并针对当前研究中存在的问题进行了展望。Phosphorus （P） is one of the essential elements for plant growth and development. However the soluble and available P in soil for plant to absorb is very limited, the ratio of effective inorganic phosphorus is about 2%-3% of the total phosphorus. According to the status quo of lacking effective phosphorus and abundant potential phos-phorus resources in soil, the topic of developing and utilizing phosphate-soluble microorganisms （PSMs） becomes a research hot spot in soil fertilizer and plant nutrition area. This paper summarized the present situation of phosphate-soluble microorganisms （PSMs） , their species, distribution, and mechanism; prospects some problems existing in present research activities.
