| 图2 氮肥添加对6种植物叶片C:P的影响(平均值±标准误差, n = 6)。N0、N1、N2和N3指氮素添加量分别为0、7、14和21 g·m-2。不同字母表示处理间差异显著(p < 0.05)。 |
| Fig. 2 Effects of nitrogen (N) addition on leaf C:P in six plant species (mean ± SE, n = 6). N0, N1, N2, and N3 represent the nitrogen addition treatment of 0, 7, 14, and 21 g·m-2, respectively. Different letters indicate significant differences between treatments (p < 0.05).
