摘要
本文用数理统计的方法,对不同立地条件、不同树龄巨峰葡萄树的叶片面积与其叶片长度、宽度和长×宽分别进行线性回归分析,得出各自高度相关的回归方程,为巨峰葡萄叶面积的测定,提供一个简单实用、可靠性较高的方法。
This paper deals with linear regression analysis separately between the leaf area and the length, the width of leaf or their product in different planting conditions and tree ages of Kyoho grape trees with the method of mathematical statistics. It obtains respective linear regression equation of high correlation, thus providing a simple and practical method of high reliability for the determination of leaf area of Kyoho grape tree.
