As shown in Table 3 , soil chemical properties had significant effects on soil bacterial community structure, with pH (P = 0.003), AN (P = 0.003), AP (P = 0.004) and SOM (P = 0.009) having highly significant effects (P < 0.01) on the bacterial community composition in the soil, and TN (P = 0.013) had a significant effect (P < 0.05) on the composition of the soil bacterial community.
