摘　　要：根际是由植物根系与土壤微生物之间相互作用所形成的独特圈带。根际微生物是植物微生态系统的重要组成部分,它们与植物病害特别是土传病害密切相关。对根际微生物的研究有利于寻找新的生物防治途径,近年来已成为植物保护研究中的热点。主要介绍了作物根际微生物互作及其在生物防治中的应用现状。特别关注了有益微生物与土传病原菌之间的进攻和防御机制。The rhizosphere is a special environment formed by the interaction between plant roots and soil microorganisms. Rhizosphere microorganisms is an important part of the plant microecosystem and is closely related to soilborne diseases and plant diseases. In recent years, rhizosphere has became a hot spot in plant protection research, as it contributes to find new avenues of biological control, reducing the selection pressure on pathogens. This paper introduces the crops rhizosphere microbial interactions and biological control application status. This paper gives special attention to the offensive and defensive mechanisms of antagonistic microorganisms between soilborne pathogens.
