不同小写字母表示同一蔗渣生物质炭添加浓度不同培养时间存在显著差异(P<0.05)ꎻ∗表示同一培养时间不同蔗渣生物质炭
添加浓度存在显著差异(P<0.05)ꎮ 下同ꎮ
Different lowercase letters indicate significant differences between different culture time at the same bagasse biochar addition concentration (P<
0.05)ꎻ ∗ indicate significant differences between different bagasse biochar addition concentrations in the same culture time (P<0.05). The
