试验采用２次回归通用旋转组合设计的分析方法，研究了玉米呼单三号不同的农艺措施组合与产量的关系。结果表明：种植密度对玉米产量影响最大，其次是氮肥，磷肥的作用不大。获得亩产２８７．８１ｋｇ的玉米产量，其栽培措施为密度３０００株／亩。亩施氮肥１０ｋｇ，磷肥５ｋｇ。
The test was conducted by using the method of two regression general rotation combination design to study the relationship between different combinations of agronomic practices and yield of maize cultivar Hwanyang No.3. The results showed that planting density had the greatest impact on corn yield, followed by nitrogenous fertilizer and no significant effect of phosphate fertilizer. 287.81kg per acre yield of corn, the cultivation measures for the density of 3000 plants / mu. Mu nitrogen fertilizer 10kg, phosphate fertilizer 5kg.
