图6 不同处理对马铃薯耗水量、成熟期株高、产量和水分利用效率的影响 处理代号见图2。误差线表示平均值的标准误(n = 3)。同一生长季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. 6 Evapotranspiration, plant height at maturity, tuber yield and water use efficiency (WUE) 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 within each growing season indicated with by different lowercase letters are significant by different at P < 0.05.
