图2 密度和株行距配置对玉米叶片着生状态的影响 柱上不同小写字母表示处理间差异显著(P < 0.05); A1、A2和A3代表种植密度分别为45,000、67,500和90,000株 hm-2; B1、B2、B3、B4和B5代表行距配置分别为(60+60)、(80+40)、(80+80)、(110+50)和(100+100) cm; Above、Ear和Under分别代表穗上第1叶、穗位叶和穗下第1叶。

Fig. 2 Effects of density and row spacing on the growth status of maize leaves Different lowercase letters above the column indicate significant difference at the 0.05 probability level among treatments; A1, A2, and A3 represent planting densities of 45,000, 67,500, and 90,000 plants hm-2, respectively; B1, B2, B3, B4, and B5 represent row spacings of (60+60), (80+40), (80+80), (110+50), and (100+100) cm, respectively; Above, ear, and under represent 1st leaf above the ear, ear leaf, and 1st leaf under the ear, respectively.
