摘要： 为探索在黔西北山区种植高油玉米高产优质的栽培模式，促进山区种植业结构调整，采用多元二次正交回归旋转组合设计，研究了高油玉米产量、产油量与四个主要栽培因子——种植密度及N、P、K肥施用量之间的关系，建立了数学模型，解析了各因素对产量、产油量的效应，通过计算机模拟寻优，筛选出了黔西北山区高油玉米高产优质的农艺综合方案：密度62463～63710株/ hm2；N肥（纯N）321.79～359.04kg/hm2；P肥（P2O5）319.94～345.32 kg/hm2；K肥（K2O）293.64～333.30 kg/hm2。

Abstract: In order to explore the planting models of high yield and quality for the high oil maize grown in north and west in Guizhou that we can accelerate the adjustment of industrial structure. The relationship between the high oil maize yield 、oil yield and four main cultural factors which contained planting density、application of N、P and K were studied, and mathematical models were established by using the multi-quadric regressive orthogonal rotary combination design . The effects of individual factor on yield and oil yield were determined by analyzing the models. After making models simulation by computer, we search and determine the optimum compositions of modeled cultivation management: density 62463～63710 individual plants/hm2 , N 321.79～359.04kg/hm2, P2O5 319.94～345.32 kg/hm2, K2O 293.64～333.30 kg/hm2.
