植物根际促生菌促生特性研究进展

Research progress on the growth-promoting characteristics of plant growth-promoting rhizobacteria

摘要:

根际微生物组是决定农作物健康状况的关键因素之一，也是调节农作物与生物和非生物环境相互作用的重要因素。植物根际促生菌(plant growth-promoting rhizobacteria, PGPR)为农作物宿主提供了多种有益作用，通过化学交流以复杂的方式与农作物、土壤相互作用，进而促进农作物生长。本文综述了PGPR对农作物的促生机制、PGPR与农作物的互作及其在农业实践中的应用，并展望了PGPR在农业实践中应用的发展趋势，以期为今后PGPR的应用和研究提供新的思路和理论支撑。

Abstract:

The rhizosphere microbiome is one of the key determinants of crop health and an important factor regulating crop interactions with biotic and abiotic environments. Plant growth-promoting rhizobacteria (PGPR) interact with crops and soil in complex ways through chemical communication to promote crop growth. This paper reviewed the growth-promoting mechanism of PGPR on crops, the interaction between PGPR and crops and its application in agricultural practice, and the development trend of the application of PGPR in agricultural practice was also prospected, aiming to provide new ideas and theoretical support for the application and research of PGPR in future.
