| 摘 要： | 用生产上常用的3个耐密玉米品种,通过改变种植方式、增加种植密度,对其产量构成相关性状进行比较分析。结果表明:双行双株种植方式可以改善玉米群体结构,提高光能利用率,有利于玉米产量构成相关性状的发育和产量的提高。先玉335综合性状表现优良,采用双行双株种植方式较常规种植产量有显著的提高,增产3 867.38 kg/hm2。

| Abstract: | By changing cultivation way and increasing planting density,the yield of 3 varieties of common tolerant-density maize increasd.The results showed that the planting mode of "double line,double-plant" improved maize population structure,improved the utilization rate of light energy and facilitated the traits of maize growth and yield.After being compared and analyzed,the yield of Xianyu 335 in "double-row doubl-plant" planting ways increased significantly,whose output had increased 3 867.38 kg/hm2.Xianyu 335 had better characters and traits than that grew in conventional planting way. |
