为研究杂交玉米新品种贵单8号在不同生态区域、不同栽培模式下的优化配套技术、良种良法用于大面积生产,采用四因素二次回归正交旋转组合设计方法对贵单8号在毕节地区的高产配套栽培技术模式进行了研究,初步建立了毕节地区中上等肥力旱地玉米高产栽培的农艺措施数学模型。通过效应分析,得出了各试验因素对毕节地区中上等肥力旱地玉米产量的影响程度顺序为N〉密度〉K2O〉P2O5,合理密植,增施氮、磷、钾肥是玉米高产的重要技术措施。经过模拟寻优提出了3种高产栽培技术模式,可根据具体情况选择推广。

By adopting the way of the four repeated factors return orthography to rotate constituting design procedures,have studied the high yield supporting cultivation technique on the newbreed of crossbred Guishan No. 8 in Bijie ,building the agriculture measure mathematic model of the breed in the first-class fertility soil of Bijie. By the effect analyzing , we get the effective degree of every experimental factor on the breed, the order is ： N 〉 density 〉 K2O 〉 P2O5. The important technique measures are to plant rationally and increase the use of nitrogen , the phosphorus, the potassic fertilizer. Have suggested three kinds of high-yield culture technique pattern by the experiment, then should choose to use it under different cases.
