关于测定柑桔叶面积方法的探讨

测定柑桔叶面积大小的方法有多种,如求积仪法、方格法、叶模法、剪纸称重法、常数法、回归方程及调整系数法等,其中以调整系数法和回归方程法的精度为高,使用也方便.通过对永州职业技术学院果园尾张温州蜜柑春叶叶面积调整系数及一元回归线性数学模型的求定,得出该柑桔叶面积调整系数为0.6835,叶长与叶面积的相关系数为0.9962,平均叶长×平均叶宽与叶面积的相关系数为0.9995;叶长与叶面积的一元线性回归数学模型为=-30.0459+6.1585X,平均叶长×平均叶宽的一元线性回归数学模型为=1.1211+0.6595X.

Approaching the Leaf-size Measurement Schemes

Several area measurement methods can be used for determining the leaf size,such as planimeter,dot grid approach,leaf model,paper-cuts weighting approach,regression equation,coefficient adjusting method and so on.Coefficient adjusting and regression equation methods are most precise and convenient ones among these approaches.We determined the spring leaf sizes of the Wenzhou orange trees grown in orchards of the Yongzhou Vocational and Technical College by using coefficient adjusting and one-dimensional regr...
