The LEfSe method identifies the significantly different abundant taxa of soil bacterial communities (A). The taxa with significantly different abundances between treatments are represented by colored dots, and from the center outwards they represent the kingdom, phylum, class, order, family, genus, and species levels. Colored shadows represent trends of significantly different taxa. Only taxa with an LDA significance threshold > 3.5 are shown in this figure. Each colored point has an effect size LDA score as shown in Fig. S1. The RDA of bacterial community and environmental factors (B). Heatmap of the correlations between phyla and soil factors (C), note ** P < 0.01; *P < 0.05. The abbreviations indicate the same as in Fig.1
