摘　　要：磷是植物生长所必需的营养元素,解磷微生物在活化难溶性磷和提高植物磷素吸收利用效率等方面具有重要作用。根系分泌物作为植物与解磷微生物之间的介导物质调控着植物和解磷微生物之间的关系。本文基于国内外关于根系分泌物对解磷微生物影响的最新研究,介绍了根系分泌物对解磷微生物生长发育、数量及种群分布、解磷能力的影响;分析总结了其主要成分如糖类、氨基酸类、有机酸类、酮类、酚酸类和其它类物质对解磷微生物的影响与作用,并对今后根系分泌物对解磷微生物影响的相关研究提出展望,为促进植物磷素高效利用研究提供参考依据。Phosphorus is an essential nutrient element for plant growth.Phosphorus solubilizing microor-ganisms play important roles in activating insoluble phosphorus and improving phosphorus uptake and utiliza-tion efficiency of plants.Root exudates as mediators regulate the relationships between plants and phosphorus solubilizing microorganisms.Based on the latest researches on the effects of root exudates on phosphorus solu-bilizing microorganisms at home and abroad,the effects of root exudates on the growth and development,quantity and population distribution and phosphorus solubilizing ability of phosphorus solubilizing microorgan-isms were introduced,and the effects of the main components of root exudates such as sugars,amino acids,organic acids,ketones,phenolic acids and other substances on phosphorus solubilizing microorganisms were analyzed and summarized in the paper.The future research directions on the effects of root exudates on phos-phorus solubilizing microorganisms were also prospected to provide references for promoting the efficient utiliza-tion of plant phosphorus.
