| 摘 要： | 以白三叶为试验材料,叶长、叶宽为测定指标,计算出叶面积与有关指标的回归方程.结果表明:回归方程与指标均达极显著直线相关,尤其是叶长、叶宽等指标与叶面积的多元回归方程y=-1.8467+0.337x1+1.9705x2-0.568z3+0.6292x4,相关系数高达0.9873.结果为白三叶叶面积的测定提供了一个简单实用的潮定方法.

| Abstract: | The regression equation,y=-1.846 7+0.337x1+1.970 5x2-0.568x3+0.629 2x4,for calculating the leaf area and relative indexes of Trifolium repens was established by using its leaf length and leaf width as measuring indexes.The results showed that there was a very significant linear correlation between the regression equation and measuring indexes and its correlation coefficient was up to 0.987 3.The mathematical model with the simple and practical advantage can be easily used in measuring leaf area of Trifolium... |
