摘要
为揭示密度、氮、钾肥施用量与先玉335玉米品种产量的关系,采用二次通用旋转组合设计,建立各因素与产量之间的数学模型,筛选高产栽培优化模式。结果表明,最佳农艺方案:种植密度62.175～71.160千株/hm2,配施纯氮266.875～284.010kg/hm2和K2O 207.645～246.270kg/hm2,产量可达10125kg/hm2以上。
The common quadratic regression combination design was used to study quantity relation between yield and main cultivating factors （ the density and amount of N and K）. Mathematical model of the main factors and yield was established and cultivation optimization mode were filtered. The results showed that the optimum agro- nomic project of the high yield （more than 10125kg/hm2） was the planting density 62. 175 -71. 160 plants/ hm2 ,amount of N of 266. 875 -284. 010kg/hm2, K20 207. 645 -246. 270kg/hm2.
