The application of microbial agent increases the relativespeciesnumberandOTU numberoffungiand bacteria inthesoil.Through KEGGmetabolic pathwayanalysis，it is foundthatmetabolismisthepathwaywiththe mostsignificant enrichmentofdiferential functions，with relative abundance of nearly 80% . Comprehensive analysis shows that microbial agent can improve the community structure of soil fungi and bacteria， promote the growth of pepper plant，and increase pepper yield.
