摘　　要：采用3因素5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叶片叶绿素a含量的影响,并建立相应回归方程。结果表明:叶绿素a含量的方程拟合程度较好。随着玉米密度的增加,间作大豆的叶片叶绿素a含量急剧增加,玉米行距和穴距曲线呈抛物线状。在低水平和高水平下,玉米穴距对间作大豆叶片叶绿素a含量的影响最大;在中等水平下,玉米密度对间作大豆叶片叶绿素a含量的影响最大。The effect of density,row spacing and hole spacing of maize on leaf＇s chlorophyll a content of the intercropped soybean were researched using orthogonal and rotational combination design with three factors and five levels,and regression equations were established. The results showed that the leaf＇s chlorophyll a content regression equations were available. The leaf＇s chlorophyll a content of intercropped soybean sharp increased with the maize density. The curve of the effect of row spacing and hole spacing of maize on soybean leaf＇s chlorophyll a content was a parabola. Maize hole had the greatest effects on the leaf＇s chlorophyll a content of the intercropped soybean with low level and high level. Maize density had the greatest effects on the leaf＇s chlorophyll a content of the intercropped soybean with medium level.
