Use of mulberry-soybean intercropping in salt-alkali soil impacts the diversity of the soil bacterial community.

ABSTRACT: Diverse intercropping system has been used to control disease and improve productivity in the field. In this research, the bacterial communities in salt-alkali soils of monoculture and intercropping mulberry and soybean were studied using 454-pyrosequencing of the 16S rDNA gene. The dominant taxonomic groups were Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi, Bacteroidetes, Planctomycetes and Gemmatimonadetes and these were present across all samples. However, the diversity and composition of bacterial communities varied between monoculture and intercropping samples. The estimated bacterial diversity (H') was higher with intercropping soybean than in monoculture soybean, whereas H' showed an opposite pattern in monoculture and intercropping mulberry.
