摘　　要：综述了根分泌物与根际微生物、病原微生物的相互影响以及根际微生物作用几方面内容。根分泌物作用于周围环境产生根际效应,影响根际微生物的生态分布、种群组成,不同抗性品种根分泌物对病原微生物表现出促进或抑制的作用;而根际微生物又会对根分泌物起到修饰限制作用,通过各种途径改变根分泌物的数量、组成。根分泌物与根际微生物间的作用是相互的。此外,根际微生物在植物养分转化与吸收、病虫草害控制、物质循环等方面发挥着不可替代的作用。Several researches about root exudates effect on rhizosphere microbes and pathogenic germs, rhizosphere microbes effect,and the function of rhizosphere microbes were summarized in this paper. Root exudates in rhizosphere can affect ecological distribution and composition varieties can improve or inhibit pathogenic germs. between root exudates and rhizosphere microbes is of rhizosphere microbes, and the root exudates from different resistant Rhizosphere microbes can also modify root exudates, so the interaction mutual. In addition, rhizosphere microbes also play an important role in the transformation and uptake of plant nutrients, prevention and control of plant diseases and insect pests, and cycling of soil matters.
