图2 行距和密度对籽粒产量、千粒重和穗粒数的影响 13.5: 密度13.5万株 hm-2; 16.5: 密度16.5万株 hm-2; 19.5: 密度19.5万株 hm-2; 22.5: 密度22.5万株 hm-2。不同小写字母表示处理间差异达0.05显著水平。

Fig. 2 Effects of row space and planting densities on grain yield, 1000-grain weight, and grains per panicle 13.5: 135 thousand plants hm-2; 16.5: 165 thousand plants hm-2; 19.5: 195 thousand plants hm-2; 22.5: 225 thousand plants hm-2. Values marked with different lowercase letters are significantly different among treatments at P < 0.05.
