摘要 杂草作为一类具有高度适性并会进一步影响当地生态系统的植物,其植物自身的根际促生菌具有改变土壤环境的能力,杂草PGPR可经过筛选以及驯化改良其活性,进而对经济作物起到促生的效果,但是目前对于杂草类PGPR的开发和利用尚处于起步阶段.杂草PGPR在适应环境过程中会导致土壤理化性质、微生物群落组成和功能的改变.因此,通过对杂草PGPR引起的促生机制进行归纳,并对目前杂草PGPR在农业生产应用方面取得的成果进行总结分析,对杂草PGPR在可持续农业发展中的作用具有一定的意义. Weeds,a kind of plant with high adaptability will further affect the local ecosystem.The plant growth promoting rhizobacteria(PGPR)of its own plant has the ability to change the soil environment.After screening weeds PGPR and improving their activity by domestication the growth-promoting effect on cash crops can be achieved.However,the development and utilization of weed PGPR is still in its infancy.Weed PGPR will cause changes in soil physical and chemical properties,microbial community composition and function during the process of adapting to the environment.By summarizing the growth-promoting mechanism caused by weed PGPR,and analyzing the current achievements of weed PGPR in agricultural production,it is proved to be significant in the role of weed PGPR in sustainable agricultural development.
