图2 不同水氮处理下耕层(0~20 cm)土壤的硝态氮含量 数据为3个小区的平均值, 误差线表示标准差。同一年度内所有处理进行多重比较, 不同字母表示处理间差异显著(P<0.05)。

Fig. 2 Nitrate nitrogen content in the 0-20 cm soil layer in different water and nitrogen treatments Data are the means of three plots and the error bar represents the standard derivation. Different letters on the bars indicate significant difference among all treatments in the same growth season (P < 0.05).
