图3. N处理对微生物生物量C、N、P及其生态化学计量比的影响(平均值+标准误差, n = 5)。N0、N1.25、N2.50、N5、N10和N20分别代表0、1.25、2.50、5、10和20 g·m-2·a-1的N施用量。不同小写字母表示N处理间指标差异显著(p < 0.05)。
Fig. 3. Effects of N treatments on microbial biomass C, N, P, and their stoichiometric ratios (mean + SE, n = 5). N0, N1.25, N2.50, N5, N10, and N20 represent N addition level at 0, 1.25, 2.50, 5, 10, and 20 g·m-2·a-1, respectively. Different lowercase letters indicate significant differences among N treatments (p < 0.05).
