| 摘 要： | 通过对不同群体结构下玉米生长发育状况及产量进行比较分析,表明低密度下株间竞争小,个体较大,但群体光利用率较低;密度过大,玉米群体内通风透光性差,不利于产量形成。通过合理调整密度。可达到增产增收的目的。本试验也为玉米高产栽培实践提供了理论依据。 |
| 关 键 词： | 玉米 大垄双行栽培 群体结构 产量 |

| Abstract: | The growth and yield of the corn in different community construction were analyzed. It showed that the competition among individuals were less, the growth of individuals were better but community light utilization was lower in low density condition. Whereas, with the higher density the aeration-euphotic ability would worse, and this would go against the yield formation. Yield and benefit could be increased by adjusting community density. The experimentation also provides theory for corn-high-yield cultivation. |
| Keywords: | corn double rows on a big ridge cultivation community construction yield |
