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3867．38kg／hm^2。

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/hm^2.Xianyu 335 had better characters and traits than that grew in conventional planting way.
