雷公藤叶面积的测算方法

On Measurement Method of Leaf Area for Tripterygium wilfordii

叶面积是树冠特征的重要标志,是估算植物特征的重要参数.通过对雷公藤叶面积、叶长、叶宽、叶长宽乘积的测量和计算,拟合了叶面积与叶长宽乘积方程,检验了叶面积测算经验公式,测算了叶相关系数,为生产实践中雷公藤叶面积的测算找到了简便、快捷、适用的方法.

The leaf area is the important mark of tree crown, and its size directly affects the productivity of the trees. Linear regression equations are established by leaf area, leaf length, leaf width and the product of the both. Empirical formula for leaf area had been tested, the relative coefficient of leaf had been calculated. It could provide an easy, quick and correct method for leaf area measurement of Tripterygiurn wilfordii.
