图2 栽培密度对抽穗期玉米穗位叶和穗下第4叶氮素含量(A)和氮/碳比值(B)的影响 LD: 低密度; MD: 中密度; HD: 高密度。柱上不同字母表示不同处理差异在0.05水平显著。

Fig. 2 Effects of planting density on nitrogen content and nitrogen/carbon ratio of ear leaf and the fourth leaf below ear of maize at heading period LD: low planting density; MD: medium planting density; HD: high planting density. Bars superscripted by different letters are significantly different at the 0.05 probability level among different treatments.
