图2 不同施氮水平对叶片氮累积量的影响(Exp.1) LNA为叶片氮累积量。处理同表1。不同小写字母表示在0.05水平上显著差异。

Fig. 2 Effects of different nitrogen application rates on leaf nitrogen accumulation of potato (Exp.1) LNA is the leaf nitrogen accumulation. Treatments are the same as those given in Table 1. Different lowercase letters indicates significant difference at the 0.05 probability level.
