叶幕结构与光合作用的关系研究

为了研究不同叶幕结构与光合作用之间的相关性，为农业生产和理论研究提供方向。本文通过对影响叶幕结构的因素：栽植密度与叶幕厚度、叶幕方位角和倾斜度、叶幕高度与行间距离、叶幕开张度、叶面积系数、叶面积密度；果树的光合特性：叶片的需光特性、果树净光合速率( Pn)的季节和日变化规律；影响光合作用的内、外界因子；光能的截留和分配的分析，提出研究中存在的问题，为以后的研究提供方向。

The Study of Relationships Between Canopy Structure and Photosynthesis

In order to study relativity between different canopy and photosynthesis, provide orientation for agriculture production and theory research.this article analyzed the effects of canopy structure:cultivated density and canopy thickness, canopy azimuth angle and gradient, canopy height and interline distance, canopy stretch degree, leaf area coefficient, leaf area density;fruit photosynthesis characteristics:leaf optical characteristics required, changes in law of fruit Pn's season and day;the internal and external effects of photosynthesis;light interception and distribution, the paper puts forward some exiting problems and provides direction for future research.
