环丙氟虫胺对土壤真菌群落多样性的影响

Soil microorganisms are an important part of farmland ecosystems, and the diversity of microorganisms is the basis for the survival of agricultural production. As a new type of bis-amide insecticide, cyproflanilide has outstanding efficacy against rice stem borer, but the effect of this insecticide on the soil environment of rice paddy fields has not been reported. In this study, we performed high-throughput sequencing of soil microorganisms in two rice paddy fields, one treated with cyproflanilide and the other untreated with cyproflanilide, by amplifying ITS rRNA sequences, and analyzed the effects of cyproflanilide use on rice paddy fields by OTU analysis, Alpha diversity analysis, flora analysis of microorganisms, Beta diversity analysis, and fungal function prediction. The results of the study indicated that the use of cyproflanilide increased the abundance and diversity of soil fungal communities in paddy fields and affected the composition of the fungal communities in paddy fields.
