Alpha and beta diversity of microbial communities. a-f: the alpha diversity index of Chao (a), Shannon (b), and Simpson (c) for the bacterial community; the alpha diversity index of Chao (d), Shannon (e), and Simpson (f) for the fungal community, different letters on the bars indicate significant differences (P < 0.05). g-l: the beta diversity of the bacterial community based on the Bray-Curtis (g), WU (i), and UU distances (h); the beta diversity of the fungal community based on the Bray-Curtis (j), WU (l), and UU distances (k).
