摘要: 研究通过3年试验,证明了玉米群体冠层特征及群体内光分布和光合效率随种植密度和施N量而有明显变化。叶面积大小是导致冠层特征变化的主导因子。平展型单交种丹玉13的籽粒产量高限出现在最大LAI变化于4.10-4.7之间,其冠层垂直方向上最大叶面积密度趋于由中部向中上部推移。叶片倾角和消光系数调节幅-于明显增加,光合速率、

Abstract: The experiments on relationship among canopy characlers, light interception and yield in maize populations with through different planting density and fertilizer quantity were conducted in 1986-1988. The results indicated that there were significant defferences in light distribution and photosynthet
