摘　　要：随着全球对可持续农业发展的日益重视,高效、环保的农业稳产增产措施成为当前研究的重要方向。植物根际促生菌(plant growth-promoting rhizobacteria,PGPR)作为一类能够促进植物生长、提高作物产量、改善土壤环境的微生物资源,在农业生产中备受关注,正在发挥越来越重要的作用。本文旨在总结PGPR接种剂在农业可持续发展中的应用潜力和挑战,展望其未来的研究方向和应用前景,可为农业可持续发展提供新思路。文章通过综述相关文献,从PGPR概念、促生长机制、影响PGPR接种剂应用效果的因素等方面进行分析,表明PGPR接种剂凭借所具有的固氮、溶磷、抑菌、分泌植物激素及改良土壤理化特性等多重功效,在推动农业可持续发展方面展现出广阔的应用潜力,但土壤理化状况、土壤生物学特性、植物类型及其根系分泌物差异、接种方式及气候条件等多重因素都会影响应用效果。未来的研究应着重于优化这些关键要素,以最大化植物根际促生菌接种剂的效用。尤其要注重筛选和培育更多适应性强、能耐受逆境的PGPR菌株,改良接种技术,优化土壤环境,调控竞争微生物群落,明确其与寄主的互作机制并加以应用,进一步提升PGPR接种剂在农业生产中的应用效果。With growing global emphasis on sustainable agricultural development,efficient and environment-friendly approaches for stabilizing and enhancing crop production have become an important direction of current research.Plant growth-promoting rhizobacteria(PGPR),as a kind of microbial resources that can promote plant growth,increase crop yields,and improve soil conditions,have garnered significant attention due to their promising application prospects and more and more important role in agricultural production.This paper summarized the application potential and challenges associated with PGPR inoculants in sustainable agriculture,outlined future research directions and application prospects,so as to provide new insights for enhancing agricultural sustainability.By reviewing relevant literature,the paper analyzed the concept of PGPR,its growthpromoting mechanisms,and the factors influencing the effectiveness of PGPR inoculants.The results indicated that PGPR inoculants presented great application potential in promoting sustainable agriculture by virtue of multiple functions including nitrogen fixation,phosphorus dissolving,potassium release,secretion of phagocytosis,antibacterial agents and plant hormones,and improvement of soil physicochemical properties.However,multiple factors such as soil physicochemical status,soil biological properties,plant types,root exudates differences,PGPR compositions,inoculation methods,and climatic conditions would affect the application effect of PGPR.Future research should focus on optimizing these critical factors,in order to maximize the effects of PGPR inoculants.In particular,attention should be paid to screening and cultivating more PGPR strains with strong adaptability and stress tolerance,improve the inoculation technology,optimize the soil environment,regulate the competitive microbial community,clarify the interaction mechanisms between PGPR and their hosts and apply them in practice,so as to further improve the application effect of PGPR.
