| 摘 要： | 柞蚕场的树冠类型和冠层结构是影响蚕场光合生产力的主要因素之一。通过测定现有三种树冠型的叶面积指数、叶量分布、光能分布等冠层结构特点,表明中干型结构优于无干型,“阶梯”树型优于中干型,表现出更合理的叶量和光能分布格局,具有最大的叶面积指数和较大的光合生产力。

| Abstract: | Tree crown form and canopy structure of the tussah-feeding oak forest are important influencing the photo-productivity of the stands. To evaluate the existing three types of crown form in mongolian oak,the characteristics of canopy struture,leaf area index,pettern of leaf and light distribution in canopy were measured. Study results show that the "Stair" form of crown demonstrates with more superiorities than the other two popular crown types in light utilization and increasing photo-productivity. |
