摘要： The effects of cropping practices on the rhizosphere soil physical properties and microbial communities of Bupleurum chinense have not been studied in detail. The chemical properties and the microbiome of rhizosphere soil of B. chinense were assessed in the field trial with three cropping practices (continuous monocropping, Bupleurum-corn intercropping and Bupleurum-corn rotation). The results showed cropping practices changed the chemical properties of the rhizosphere soil and composition, structure and diversity of the rhizosphere microbial communities. Continuous monocropping of B. chinense not only decreased soil pH and the contents of NO3--N and available K, but also decreased the alpha diversity of bacteria and beneficial microorganisms. However, Bupleurum-corn rotation improved soil chemical properties and reduced the abundance of harmful microorganisms. Soil chemical properties, especially the contents of NH4+-N, soil organic matter (SOM) and available K, were the key factors affecting the structure and composition of microbial communities in the rhizosphere soil. These findings could provide a new basis for overcoming problems associated with continuous cropping and promote development of B. chinense planting industry by improving soil microbial communities.
