摘　　要：采用4因素二次回归正交旋转组合设计方法,对杂交玉米新品种贵单8号在毕节地区的高产配套栽培技术模式进行了研究,建立了该品种在毕节地区中上等肥力土壤高产栽培的农艺措施数学模型。通过效应分析,得出各试验因素对该品种产量的影响程度顺序为N>密度>K2O>P2O5,合理密植,增施氮、磷、钾肥是实现该品种高产的重要技术措施。经过模拟寻优提出了该品种的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 new breed 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, get the effective degree of every experimental factor on the breed, the order was ： N 〉 density 〉 K20 〉 P2 05. The important technique measures were to plant rationally and increase the use of nitrogen, the phosphorus, the potassic fertilizer. Have suggested three kinds of high-yleld culture technique pattern by the experiment, then should choose to use it under different cases.
