“f_; g_” and “o_; g_” represent taxa not grouped into any known genera within these families and orders, respectively. SC, SQ, SX and SH represent bacterial communities from ‘Changguo Sang’, ‘Chuan Sang No.7637’, ‘Xin Lunjiao’, and ‘Hong Guo No.2’ in spring, respectively. AC, AQ, AX and AH represent bacterial communities from ‘Changguo Sang’, ‘Chuan Sang No.7637’, ‘Xin Lunjiao’, and ‘Hong Guo No.2’ in autumn, respectively. Data shown are means ± standard deviation of three replicates. Means with different letters are significantly different (p < 0.05).
