在黔中玉米连作种植区域，采用三因素二次正交旋转组合回归设计试验，研究在不同种植密度和施氮量情况下，配合施用复合微肥的农艺效果。结果显示：试验因子对株高、穗粗、穗行数的影响变化不大；而对植株茎粗度、穗长、行粒数、百粒重、产量均有不同程度的影响。建立了产量与密度、氮肥、复合微肥的三元二次回归模型，经解析得到产量大于750 kg/667m2的优化栽培组合方案：种植密度为3149~3578株/667m2，施氮量为27.58~34.94 kg/667m2，复合微肥为3971~4225 g/667m2。

Through designing the experiment with three factors quadratic orthogonal rotation combination regression, the study explored the effects of applying compound micronutrient fertilizer under different planting densities and nitrogen fertilizer levels in the continuous cropping area of corn in central Guizhou. The results showed that the influences of the test factor on plant height, spike diameter and row number of spike was of few variety;for the plant stem diameter, the spike length, the amount of grain per row, the hundred-grain weight and the yield, there were different degrees of influence. The study established a ternary quadratic regression model among yield and density, nitrogen fertilizer as well as compound micronutrient fertilizer. Based on the analysis, the optimum cultivation combination with the yield larger than 11 250 kg/hm2 was found out as follows:planting density was 47 235~53 670 plants/hm2, the nitrogen fertilizer rate was 413.7~524.1 kg/hm2, and the compound micronutrient fertilizer rate was 59 565~63 375 g/hm2 .
