Figure 2.

Effects of different fertilization treatments on the relative abundance of soil bacterial communities. The figure shows the top six phyla (A) and the top twenty genera of bacteria (B). The phyla with relative abundances below 1% were grouped as “Others.” The definitions of CK, SDH.2, SDH.3, SDH.4, SKR.2, SKR.3, SKR.4, SYT.2, SYT.3, and SYT.4 are shown in Figure 1. The different letters in the figure indicate a significant difference at p < 0.05.
