The present research aimed to assess the effects of plastic film mulch on microbial diversity and comm­unity in the Tartary buckwheat rhizosphere. Treatments included regular cultivation, polyethylene film mulch on the whole ground and furrow-ridge plastic film mulch (FR). We found that FR prominently reduced the relative abundance (RA) of the members of phylum Mortierellomycota while increasing the RA of the members of phylum Ascomycota, especially Fusarium and Dokmaia. FR also reduced the predicted sequences related to mannan degradation and the biosynthesis of phospholipases, phosphatidylglycerol and ubiquinol. This study suggests that it is necessary to evaluate the effect of mulch techni­ques on pathogenic and mycotoxin-pro­ducing species before application.

Abstract


The present research aimed to assess the effects of plastic film mulch on microbial diversity and comm­unity in the Tartary buckwheat rhizosphere. Treatments included regular cultivation, polyethylene film mulch on the whole ground and furrow-ridge plastic film mulch (FR). We found that FR prominently reduced the relative abundance (RA) of the members of phylum Mortierellomycota while increasing the RA of the members of phylum Ascomycota, especially Fusarium and Dokmaia. FR also reduced the predicted sequences related to mannan degradation and the biosynthesis of phospholipases, phosphatidylglycerol and ubiquinol. This study suggests that it is necessary to evaluate the effect of mulch techni­ques on pathogenic and mycotoxin-pro­ducing species before application.
