Effects of Intercropping Maize with Aconitum vilmorinianum Kom.on Rhi-zosphere Microbial Community Diversity
In order to reveal the effect of Aconitum vilmorinianum Kom.intercropping on the community compo-sition and diversity of rhizosphere soil,the single cultivation of A.vilmorinianum Kom.(S),the A.vilmorinianum Kom.intercropping maize 2∶1 mode(I1)and 4∶2(I2)mode were collected respectively of A.vilmorinianum Kom.rhizo-sphere soil.Using Illumina-MiSeq high-throughput sequencing technology to analyze the fungal and bacterial community composition and diversity,in order to provide a certain theoretical basis for the advantages of A.vil-morinianum Kom..other crops intercropping.The results showed that the intercropping maize of A.vilmorinianum Kom.increased the abundance and diversity of the microbial community in the rhizosphere soil of the A.vil-morinianum Kom.The dominant bacteria phyla in the rhizosphere soil of A.vilmorinianum Kom.are Gemmati-monadete,Proteobacteria,Acidobacteria and Actinobacteria,and there are 12 dominant bacteria genera.The dom-inant fungal phyla are Mortierellomycota,Ascomycota and Basidiomycota,and there are 8 dominant fungal gene-ra.Redundancy analysis(RDA)showing that available phosphorus and total potassium has the greatest influence on the structure of soil microbial community;correlation analysis also shows that soil physical and chemical indi-cators are closely related to different dominant bacteria phyla.In this study,high-throughput sequencing methods were used to analyze the effect of the intercropping of A.vilmorinianum Kom.and maize on the rhizosphere mi-crobial community structure,and provide a theoretical basis for further revealing the dominant mechanism of A.vilmorinianum Kom.and maize intercropping.
