  1. The first letter in the sample name represents the sampling area; the second represents tree species; the third indicates rhizosphere or bulk soil; C, Changlongjie; L, Lianmeng; L, Ligustrum lucidum; B, Broussonetia papyrifera; R, rhizosphere; B, bulk soil. Data are reported as means ± standard deviations (n = 3). Different letters indicate significant differences between the four samples at same site (p < 0.05).
