摘　　要：干旱胁迫是植物受到的重要非生物胁迫之一,不仅对植物的生长繁殖有严重影响,造成作物的减产,还会破坏生态环境。目前,人们除了通过建设灌溉工程等措施人为改善植物的生长环境来提高植物的存活率外,还以植物生长促进微生物(PGPM)作为植物生长调节剂来维持植物正常的生理生化反应,缓解干旱胁迫对植物造成的不良响应。本文以干旱胁迫下植物生长促进微生物如何促进植物生长为研究目的,通过查阅文献资料,对相关内容进行总结,旨在阐明干旱胁迫下植物生长促进微生物对植物生长的正向调控作用。Drought stress is one of the most important abiotic stresses on plants,which not only affects the growth and reproduction of plants seriously,resulting in reduced crop yield,but also damages the ecological environment.At present,besides improving the growth environment of plants artificially by constructing irrigation projects,plant growth promoting microorganisms(PGPM)are also used as plant growth regulators to maintain normal physiological and biochemical reactions of plants and alleviate the adverse responses caused by drought stress.This paper aimed at studying how plant growth promoting microorganisms promoted plant growth under drought stress,and summarized relevant contents by consulting literature,aiming to clarify the positive regulation of plant growth promoting microorganisms on plant growth under drought stress.
