图5 不同处理对马铃薯单株干物质积累的影响 处理代号见图2。误差线表示平均值的标准误(n = 3)。同一生育时期标明不同小写字母的柱值表示各处理的平均值(n = 3)在P < 0.05水平上差异显著。

Fig. 5 Weight of dry matter per plant as affected by different treatments Treatments are as these described in Fig. 2. Error bars indicate the standard error for each date point (n = 3). Mean value (n = 3) columns at each growth stage indicated with different lowercase letters are significant by different at P < 0.05.
