Fig. 3From: Diversity patterns of soil microbial communities in the Sophora flavescens rhizosphere in response to continuous monocroppingAlpha diversity of soil microbial communities at sites after various years of continuous monocropping with S. flavescens. The top and bottom panels show the estimates of bacterial and fungal alpha diversity of each sample, respectively. Different lowercase letters above the boxplots indicate significant differences between different samples according to one-way ANOVA with Duncan’s multiple range test (P < 0.05)Back to article page
