摘要
采用三因素五水平二次回归正交旋转组合设计,研究玉米品种、密度、施肥措施对西昌地区玉米产量形成的作用效应,建立回归模型并分析各因子的作用规律。结果表明,品种对西昌地区玉米产量影响最大;品种与种植密度之间存着显著的互作效应,文中提出了部分川单系列玉米新品种在西昌地区的栽培模式。
Quadratic orthogonal regressive rotation design of three factors is applied to study the effect of varieties, density and fertilization to maize yield in Xichang ecological area. The results show that variety is the most important factor for maize yield in this area and significant interaction is found be- tween variety and density. And cultivation model of part chuandan maize hybrids are also analysed and discussed in this paper.
