| 摘 要： | 以玉米新品种晋单63号为试验材料,采用二元二次正交回归旋转组合设计,研究该品种产量与种植密度、施氮量等主要栽培因素间的关系,建立了二因素与产量的数学模型:Y=10 008.063 63+63.496 87X1+245.347 70X2-684.531 61X12-116.406 59X22+35.375 37X1X2。通过寻优,确立了晋单63号最佳种植密度为78 108.2株/hm2,施氮量为300.0 kg/hm2,在该组合措施下,可获得10 137 kg/hm2的较高产量,为该品种的大面积生产提供了科学指导。并分析了各因素对晋单63号产量的影响,发现种植密度的影响大于施氮量。
