| 摘 要： | 运用二次回归正交旋转组合设计,研究优质高产薏仁米新品种薏2006489在贵州高海拔地区产量与播种时期、种植密度及施肥量等主要栽培因素间的关系,建立了各因素与产量指标的数学模式:Y=9.2826+0.7427X1+0.981 0X2+0.648 1X3+0.5X1X2-0.1X1X3+0.075X2X3-1.192X12-0.159 6X22-0.408 8X32;确立了优质高产新品种薏2006489在贵州西部高海拔地区高产栽培合理的播种时期、种植密度和施肥量的优化方案:播种时期是4月22日,密度为8500株/667 m2,施氮量为23 kg/667 m2。在这一组合措施下,可获得406.94 kg/667 m2的最高产量。各因素对优质高产新品种薏2006489产量的影响是种植密度>播种时期>施肥量的回归模型。

| Abstract: | The orthogonal design of ternary quadratic regression was employed to unravel the relationships among maize yield and sowing time, plant density and fertilization of a new myotonin cultivar ＂ Coix 2,006,489＂ in high altitude areas of West Guizhou in this investigation. Mathematical model of the various factors and yield indicators was established as Y = 9. 282 6 ＋ 0. 742 7 X1 ＋ 0.981 X2 ＋ 0. 6481 X3 ＋ 0. 5 X1X2 - O. 1X1X3 ＋0. 075X2X3 - 1. 192X12 -0. 1596X22 -0. 4088X32. In high altitude areas of West Guizhou, the op- timal scheme of Coix 2006489 was as follow： the sowing period of April 22, the density of 8.5 million/667 2 m , as well as nitrogen application of 23 kg/667 m2 based on which, maximum yield （406. 94 kg/667 m2 ） may be obtained. Among the factors influencing yield, sowing time ranked the first, followed by fertilizer and density. |
