摘要: 在四川不同生态条件下,采用3因素二次正交旋转组合设计,研究了大穗型新品系"异源2号"小麦播种期、密度、施氮量及其他因素对小麦产量的作用及其影响,建立了最佳农艺措施的数学模型。结果表明;3种因素对小麦产量的影响大小并按顺序依次为:播期 > 密度 > 施氮量;施氮量 > 施磷量 > 密度。并得出高于5250、6000、7500kg/hm2产量的优化栽培方案。

关键词: 小麦, 二次正交旋转组合设计, 优化栽培技术

Abstract: Study is done on effect of three factors, sowing date, density, application of nitrogen fertilizaer and others by using the quadratic orthogonal rotationl combination design, on the grain yield of wheat in different ecological conditions. The results show that the effects on wheat gield are sowing date > density > application of nitrogenous fetilizer and nitrogenous fetilizer > phosphoric fertilizer > density. The mathematial model of the cultural practices has been estabished for high yielding wheat, higher than 5250kg, 6000kg, 7500kg/hm2.
