摘要
本文对山西省种植的不同株型的五个玉米品种，在高产栽培条件下，研究了群体内冠层叶面积的铅直分布规律。结果表明：不同群体的冠层的叶面积指数的铅直分布状况符合逻辑斯谛方程。此外，还对不同品种的冠层结构的特点进行了分析比较。
his paper studied the leaf area vertical distributions of five maize populations,with different plant types under high grain yield conditions in Shanxi.The results showed that the vertical distributions of leaf area indexes in canopy were represented well by Logistic equations.In addition,the differences in distributions of canopy leaf area were discussed among varieties(populations).The characteristics of canopy architectures in these populations may be considered as criteria of high grain yield for maize populations.
