| 摘 要： | 应用三因素五水平回归正交旋转组合设计的方法,研究了玉米密度、行距和穴距对间作大豆光合速率的影响,并建立相应回归方程.结果表明:方程拟合程度较好,玉米密度、行距和穴距对间作大豆光合速率有显著的影响.玉米密度对间作大豆光合速率的效应呈现倒抛物线曲线,玉米行距和穴距对间作大豆光合速率的效应呈现抛物线曲线.玉米行距和穴距对间作大豆光合速率具有交互效应.在玉米生产密度下,适当增加玉米生产的行距和穴距,可以提高间作大豆的光合速率.

| Abstract: | The effect of density,row spacing and hole spacing of maize on soybean photosynthetic rates were researched using orthogonal and rotational combination designs with three factors and five levels,and regression equation were established.The results showed that the regression equations were available,and the effects of density,row spacing and hole spacing of maize on soybean photosynthetic rates were significant.The effect curve of density of maize on soybean photosynthetic rate was a reverse parabola.The effect curves of row spacing and hole spacing of maize on soybean photosynthetic rates were parabola.There was interaction of the effects between row spacing and hole spacing of maize on soybean photosynthetic rates.The soybean photosynthetic rates could be advanced if the row spacing and hole spacing of maize production were a little raised under the present maize production density. |
