| 摘 要： | 近年来对土壤微生物和植物之间互作关系的研究越来越受到关注,植物的根际分泌物直接或间接的影响了根际微生物群落结构,同样,根际微生物也以各种不同方式影响着植物根际的土壤理化性质、根际分泌物释放、土壤物质循环等。本文从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多样性的影响这两方面对土壤根际微生物与植物之间相互影响的途径与机制进行了综述。

The Interaction Mechanism Between Plant Rhizosphere Secretion and Soil Microbe: A Review |
| |
| 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. |
