图1. 不同处理下达乌里胡枝子的叶片N含量(A)和净光合速率(B)的变化(平均值±标准误)。不同小写字母表示同一密度下不同施氮量间差异显著(p < 0.05), 不同大写字母表示不同密度下差异显著(p < 0.05)。ns, p > 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001。
Fig. 1. Changes in leaf nitrogen (N) concentration (A) and net photosynthetic rate (B) of Lespedeza davurica under different treatments (mean ± SE). Different lowercase letters indicate significant difference among N addition treatments under the same density at p < 0.05 level, while different uppercase letters indicate significant difference among density treatments at p < 0.05 level. ns, p > 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001.
