在晋西滩地上，采用五元二次通用正交旋转回归组合设计（1／2部分实施）的试验方法，选取对玉米产量影响较大的施肥量、密度等农艺措施，进行高产栽培技术模型试验研究，结果表明各因素影响玉米产量的顺序为：有机肥＞三元复合肥＞密度＞硝铵＞碳铵；并求出目标产量为9000kg／hm2～9750kg／hm2时的最佳农艺组合为：有机肥37500kg／hm2～67500kg／hm2，碳铵375kg／hm2～525kg／hm2，三元复合肥300kg／hm2～600kg／hm2，硝铵150kg／hm2～375kg／hm2，密度45000株／hm2～52500株／hm2。
On the ground of Jinsai Beach, using five yuan quadratic universal orthogonal rotation regression combined design (1/2 part of the implementation of the test method, select the corn yield greater impact on the amount of fertilizer, density and other agronomic practices, high-yield cultivation techniques model The results showed that the order of the factors influencing the yield of maize was organic fertilizer> ternary compound fertilizer> density> ammonium nitrate> ammonium bicarbonate; and the optimum agronomic combination for the target yield of 9000kg / hm2 ~ 9750kg / hm2 was : Organic fertilizer 37500kg / hm2 ~ 67500kg / hm2, ammonium bicarbonate 375kg / hm2 ~ 525kg / hm2, ternary compound fertilizer 300kg / hm2 ~ 600kg / hm2, ammonium nitrate 150kg / hm2 ~ 375kg / hm2, density 45000 / hm2 ~ 52500 Strain / hm2.
