窄行密植对大豆群体冠层结构及光分布的影响

Effects of planting with narrow line and proper density on canopy structure light penetration of soy bean

通过不同密度和宽、窄行距配置试验可知,大豆在保持合理群体密度下,实行窄行密植,可改善大豆植株群体的透光性和叶面积的空间分布,具有较好的冠层结构,提高了群体光能利用率,从而提高大豆的群体生产能力,获得较高的产量。

From trial of different density and collocate, it can be known that planting with narrow line and proper density can improve light penetration of soy bean colony and space distribution and has a better canopy structure, enhance colony solar utilize rate, thereby, increases soy bean colony productive ability and gains a higher yield.
