Soil rhizosphere bacterial community structure of different planting systems in 2021. (A) Principal coordinate analysis (PCoA). Regarding the PCoA analysis of the bacterial community, in PCoA1, fallow X was significantly different from the other three planting methods; (B) percentage of bacterial community structure at the phylum level. In the detection of bacterial phylum analysis, Proteobacteria and Acidobacteriota had the highest richness; (C) functional prediction of bacterial communities in different planting patterns by FAPROTAX. Twenty representative functional groups were predicted and analyzed in total; (D) ACE, Chao1, and Shannon diversity indices. In the analysis of abundance and diversity, the significance of X was significantly higher than that of the other three planting systems.
