摘要: 采用三因素二次正交旋转组合设计,研究了大穗型异源2号小麦在雅安生态条件下,播种期、密度、施氮量对小麦产量的作用及其影响,建立了最佳农艺措施数学模型,结果表明,三种因素对小麦产量的影响大小按顺序依次为:播期 > 施氮量 > 密度,并得出大于5250kg/hm2产量的栽培方案。

关键词: 小麦, 数学模型, 二次正交旋转组合设计

Abstract: Study on effect of three factofs, sowing date, density, application of nitrogen fertilization by using the quadratic orthogoual rotationl combination desigen, on the grain yield of wheat in Yaan shows that the sowing date > application of nitrogen fetilization > density. The mathematical model of the cultural practices has been established for high-yielding wheat, and a yield over 5250kg per hm2 may be obtained.

Key words: WHEAT, MATNEMTICAL MODEL, QUADRATIC ORTHOGONAL ROTAIONAL COMBINATION DESIGEN
