通过对板栗 4个品种叶片长度、宽度、叶长宽和与叶面积之间的相关分析 ,建立了数学关系式。经实际检验得知 :回归方程法只适用于单一品种 ,测定叶面积迅速准确 ;板栗叶面积公式法则适于所有板栗品种的叶面积估算 ,具有较高的精度
Through the correlation analysis between leaf length, width, leaf length and leaf area of four varieties of chestnut, the mathematical relation was established. The actual test shows that regression equation method is only suitable for a single variety and the leaf area is determined quickly and accurately. The formula of chestnut leaf area formula is suitable for leaf area estimation of all chestnut varieties with high precision
