Research Progress on Growth-promoting Mechanism and Application of Plant Growth-promoting Rhizobacteria

doi:10.13304/j.nykjdb.2023.0654

Abstract

Abstract:

At present， the soil of cultivated land is facing problems such as continuous cropping obstacle， salinization and soil pollution， which seriously threaten crop yield and food security. The plant growth-promoting rhizobacteria （PGPR） has a good application potential in improving crop yield， reducing disease and remediating soil. However， in the actual application process， the use of PGPR is seriously limited by unclear function mechanism， immaturity application technology and unstable effect. This paper systematically reviewed the classification， growth-promoting mechanism， application effect and technology of PGPR， analyzed the existing problems in this field and discussed the development direction of PGPR in the future， which would provide new ideas and theoretical support for the application and research of PGPR in the future.

Key words: plant growth-promoting rhizobacteria, crops, growth-promoting mechanism, application technology

摘要：

目前，耕地土壤面临连作障碍、盐碱化、土壤污染等问题，严重威胁作物产量和粮食安全，植物根际促生菌（plant growth-promoting rhizobacteria， PGPR）具有提高作物产量、抵御病害、修复土壤等作用，具有良好的应用前景。然而，根际促生菌在实际应用过程中存在作用机制不明确、应用技术不成熟及效果不稳定等问题，严重限制其应用。系统梳理了根际促生菌的分类、促生作用机制、在作物上的应用效果及应用技术的研究进展，分析了该领域目前存在的问题，并探讨了今后植物根际促生菌的发展方向，以期为植物根际促生菌的应用和研究提供新的思路和理论支撑。
