果树叶片叶面积是衡量果树生产能力大小的重要指标。研究适于多种果树、简单易行、准确度高的单叶面积测定方式及数学计算公式,以改进目前通用叶面积计算公式(S=2/3ab,a为叶宽,b为叶长)误差较大和田间调查较费工的缺点。本文从果树叶形指数入手建立一组新的单叶面积计算公式,并且对不同树种(品种)的果树进行验证计算,实验证明,本文推出的一组新的计算公式误差较小,能够准确地计算单叶面积,内容报道如下。
Fruit leaf area is a measure of the size of fruit trees an important indicator of productivity. To study single leaf area determination and mathematical formula suitable for a variety of fruit trees, simple and feasible, high accuracy, to improve the current common leaf area calculation formula (S = 2 / 3ab, a leaf width, b leaf length) The error is larger and field investigation more labor shortcomings. In this paper, a new set of formulas for calculation of single-leaf area was established based on the leaf index of fruit trees. And the fruit trees of different tree species (varieties) were validated and calculated. The experiment proves that a new set of calculation formulas introduced in this paper has less error and can accurately Calculation leaf area, the content reported below.
