研究不同株行距配置对玉米主要农艺性状和产量的影响，寻求通过改变种植模式提高产量的新途径。以‘郑单136’为供试品种，采用随机区组设计，探讨同一种植密度下8种不同株行距配置对其主要农艺性状及产量的影响。结果表明，在相同管理条件下，不同株行距配置在增产效应上表现出明显的差异，最佳的株行距配置为100 cm等行距、株距30 cm、双株种植，比对照增产6.7%。而在抗病性、植株性状等主要农艺性状并没有表现出显著的差异。因此，为了取得更高的产量，建议‘郑单136’在鄂北岗地常规种植模式下将株行距配置改为100 cm等行距、株距30 cm、双株种植。

The objectives of this study were to investigate the influences of row-spacing on maize agronomic characteristics and yield, and to seek new ways to increase yield by changing row-spacing. Field experiments were conducted in 2014 with randomized block design to study effects on agronomic characteristics and yield in eight row-spacing. Test variety was‘Zhengdan 136’. The results showed that under the same culture condition, there were significant differences in yield but no obvious difference in disease resistance, plant traits and other major agronomic traits among different row-spacing. The best row-spacing was 100 cm equal row and 30 cm plant spacing in double plants which increased yield by 6.7% compared with CK. Therefore, in order to gain higher yield under general planting in humpy ground in Northern Hubei,the row-spacing‘Zhengdan 136’should be changed to 100 cm equal row and 30 cm plant spacing in double plants.
