Table 3 Catabolic diversity (measured by the average well-color development (AWCD), Shannon index, and substrate richness, was determined using Biolog EcoPlates) for the rhizosphere bacterial communities across different treatments. Different letters within columns indicated significant differences at P < 0.05.
Treatment | AWCD | Shannon’s diversity index(H) | Substrate richness(S) |
|---|---|---|---|
CK | 0.63 ± 0.13b | 3.08 ± 0.08bc | 20.67 ± 1.78b |
FO | 0.60 ± 0.06b | 3.03 ± 0.03c | 18.67 ± 1.10b |
PL | 1.04 ± 0.18a | 3.20 ± 0.06ab | 26.67 ± 2.22a |
BP | 1.09 ± 0.02a | 3.29 ± 0.01a | 29.00 ± 1.00a |
