摘要
通过大田植株分层切片法分析比较了 3个水稻供试品种在抽穗期和灌浆期的冠层叶片叶倾角、叶面积及其垂直分布概率和叶日积随生育进程而变化的规律等冠层结构特征 ,并通过数学方法对不同品种的叶面积垂直分布密度进行了模拟。结果表明
Canopy characteristics of three rice varieties during different growing period,such as leaf inclination angle,leaf area index (LAI) and their probability of vertical distributions,were analysed and compared by stratifical truncation.The result showed that canopy characteristics of different rice varieties were markably different.Meanwhile,vertical density distribution of LAI were modeled in this paper.
