摘要
植物根际促生菌具有促进植物生长、提高作物产量及诱导植物产生系统抗性来抵御生物和非生物胁迫的作用。目前,随着绿色可持续现代农业的大力发展,微生物菌肥成为备受青睐的新型肥料。因此,有关根际促生菌的分离、鉴定、与植物的互作机制以及利用根际促生菌制备微生物肥料等方面的研究日益受到重视。本文系统综述了根际促生菌促进植物生长的机理(包括固氮、溶磷、解钾、溶铁、分泌植物激素、释放挥发性物质等)和增强植物抵御生物胁迫(包括病原菌、害虫等)及非生物胁迫(干旱、盐害、重金属等)方面的研究进展,并针对根际促生菌的未来研究方向进行了展望。
Plant growth promoting rhizobacteria(PGPRs)exist in soil or are attached to plant roots with the functions of growth promotion and yield improvement.In addition,PGPRs can enhance plant resistance to biotic and abiotic stresses.Nowadays,with the development of green and sustainable agriculture,microbial fertilizer has become a new type of popular of fertilizer.Therefore,researches on isolation and characterization of PGPRs,their interaction with plants and the development of microbial fertilizer containing PGPRs are attracting more and more attentions.In this paper,the research advances on PGPRs,including their growth promotion mechanisms(nitrogen fixation,phosphorus solubilization,potassium releasing,iron solubilization,plant hormone secretion,release of volatile organic compounds etc..)and tolerance enhancement of biotic stresses(pathogens and pests)and abiotic stresses(drought,salinity and heavy metals),were reviewed.Finally,the research directions on PGPRs in the future were prospected.
