Abstract Purpose This study was purposely designed to understand the effects of intercropping banana and sweet potato on soil microbial community. The research question addressed was what were the differences in population number, population diversity and dominant population of soil microorganisms between interplant bananas with sweet potatoes and banana monoculture. Methods The Illumina MiSeq high-throughput sequencing technology was used to detect and analyse the population composition and structure of soil microorganisms in banana field. Results The results showed that from May to September, the number of soil bacterial population in intercropping sweet potato was 5.54-28.67% higher than that in monoculture, and the richness and diversity of the population were significantly or extremely significantly higher than that in monoculture. The number of dominant bacterial population was less than that in monoculture, and the relative abundance of non dominant population was 10.58 - 58.81% higher than that in monoculture. The number, abundance and diversity of soil fungal populations in intercropping were higher than those in monoculture. Conclusions The intercropping of banana and sweet potato has a significant effect on regulating the composition structure of soil microbial population and improving the abundance and diversity of microbial population. There has a great significance to improve the micro ecological environment of banana root soil and promote the stable and sustainable development of banana industry.
