Plastic filming mulch(PFM)practice is critical for agricultural production in arid and semi-arid areas in the world.There is evidence that PFM alters soil microbial populations and soil nutrients,but a full understanding of changes and functions in soil properties is still unclear.In particular the role of rhizosphere microorganisms in soil nutrients utilization and their changes with plant growth is lacking.In this study rhizosphere microbial populations,rhizosphere microbial carbon utilization,rhizosphere soil nutrients and plant growth traits were measured to investigate how quickly rhizosphere soil microbial populations and functions response to land management of plastic film mulching practice,and its direct or indirect effects on soil nutrients and plant growth.Our results indicate that rhizosphere microbial populations and functions have been significantly altered by changing soil temperature and water content under PFM treatment.Furthermore,the linear regression coefficients among rhizosphere soil nutrients,microbial populations,microbial functions,and plant yields were significantly changed under PFM treatment,which demonstrated the ability of PFM practice to modify soil microbial populations and functions,and might help reveal rhizosphere rich microbes locally influencing nutrients transportation to plants,erthance improving plant growth traits under PFM treatment.
