| 图1 不同氮添加水平(x)和铵硝态氮配比(y)下木荷幼苗的光合特征参数差异分析(平均值±标准误)。不同小写字母表示不同氮添加水平和铵硝态氮配比处理间差异显著(p < 0.05)。LN、MN、HN, 氮添加水平分别为0.5、1.0、2.0 mmol·L-1。**, p < 0.01; ***, p < 0.001。 |
| Fig. 1 Photosynthetic characteristics parameters of Schima superba seedlings under different nitrogen addition levels (x) and NH4+-N to NO3--N ratios (y) (mean ± SE). Different lowercase letters indicate significant differences between varying nitrogen addition levels and NH4+-N to NO3--N ratios (p < 0.05). LN, MN and HN simplified as nitrogen addition level of 0.5, 1.0 and 2.0 mmol·L-1, respectively. **, p < 0.01; ***, p < 0.001. |
