| 摘 要： | 通过对大豆生殖生长期冠层结构特征、冠层辐射特性变化的分析表明,存在产量差异的3个大豆品种(系)生殖生长期有着不同的冠层发展动态,高产品种北丰11的群体LAI和LAD相对较大,叶片在各个方向分布均匀,平均叶倾角小,相应地辐射透过系数较低,光截获的比例相对较高,有利于干物质的同化积累,光能利用率高。

| Abstract: | Through analyzing the traits of canopy structure and radiation during reproductive stage in soybean cultivars or lines, the results showed that there were different dynamic of population in three different yielding soybean cutivars. LAI and LAD of high yielding colony of Beifeng 11 were large, foliar distribution trended to unifrom and mean foliage inclination angle was small, which made radiation penetration low, the ratio of light interception high and benefited for dry matter accumulation and rising radiation use efficiency. |
