摘要:

为揭示植物与土壤微生物之间互作关系的途径与机制,综述了根际有益微生物对植物生长发育的促进作用以及植物根际分泌物对土壤微生物的影响这2个方面的研究进展,主要分述了根际促生微生物PGPM对植物生长发育的促进作用;生防微生物BCA对植物生长发育的促进作用;根系分泌物的组成;根系分泌物的功能;根系分泌物影响土壤微生物的途径等方面的内容。指出植物与土壤微生物之间互作关系机理的研究还不够深入,对PGPM菌株的筛选和适应能力的研究,生防微生物的生态适应性及对靶标病原菌的作用机制研究,对根系分泌的分离鉴定方法的优化及化感作用途径等需要更深入探究。今后应加大现代分子生物学技术在相关研究中的应用,将分子生物学技术与传统培养方法相结合,进一步揭示植物与土壤微生物之间的互作关系。

Abstract:

To reveal the pathways and mechanisms of the interaction between plants and soil microorganisms, the authors reviews the research progress of the promotion of plant growth and development by rhizosphere beneficial microorganisms and the effects of plant rhizosphere secretions on soil microbes, mainly include the promoting effect of rhizosphere-promoting microorganism PGPM on plant growth and development, the promotion of biocontrol microorganism BCA on plant growth and development, the composition of root exudates, the function of root exudates, and the pathway of root exudates affecting soil microbes, etc. The authors point out that the research on the mechanism of interaction between plants and soil microorganisms is not deep enough. The research on the screening and adaptability of PGPM strains, the ecological adaptability of biocontrol microorganisms and the mechanism of action on target pathogens, the separation of root secretion, the optimization of the identification method and the allelopathic approach all need to be further studied. In the future, the application of modern molecular biology technology in related research should be increased, and the interaction between plant and soil microorganisms should be further revealed by combining molecular biology techniques with traditional culture methods.

Key words: soil beneficial microorganisms, plant rhizosphere secretions, soil microbial diversity, interaction, pathway, mechanism
