图4. 植物叶片对N、P的利用效率(A)和再吸收效率(B)(n = 12)。LCC, LCQ, LVR, PLL同图1。NUEN, N的利用效率; NUEP, P的利用效率。不同小写字母代表不同恢复阶段之间的差异显著(p < 0.05)。

Fig. 4. Utilization efficiency (A) and reabsorption efficiency (B) of N, P of leaf (n = 12). LCC, LCQ, LVR, PLL see Fig. 1. NUEN, nutrient use efficiency of N; NUEP, nutrient use efficiency of P. Different lowercase letters indicate significant differences at different restoration stages (p < 0.05).
