| 摘 要： | 采用五元二次正交旋转组合设计,对亚麻原茎产量与锌肥、铜肥、硼肥、锰肥和钼肥5因素的定性定量关系的研究,建立了亚麻原茎产量与五项因子的数学模型,并对回归模型进行显著性测定,结果表明:试验原茎产量数据与所采用的二次数学模型符合,二次回归方程与实际情况拟合较好.对模型进行解析和模拟检验,最终在1 055个组合方案中农艺组合方案最优为:667 m2喷施锌肥(X1)641.0～671.8 g、铜肥(X2)477.2～503.0 g、硼肥(X3)285.0～315.0 g、锰肥383.0～417.0 g、钼肥22.4～24.1 g,可获得较高的原茎产量.

| Abstract: | The experiment was conducted with the method of the combination design of orthogonal rotating regression,regarding five microelement: Zn,Cu,Ba,Mn,Mo as decisive varieties to study the effect on flax stem Yield.A mathematical model involving in the five factor affecting the flax stem yield was established and analyzed.The results showed that the models are extremely remarkable and coincident with practice.And five factors have great effect on stem yield and there are interactions among them.Finally,the method of agronomic combination design was the best one among 1 055 presented:667 m2 to spray Zn fertilizer 641.0-671.8 g,Cu fertilizer 477.2-503.0 g,Ba fertilizer 285.0-315.0 g,Mn fertilizer 383.0-417.0 g,Mo fertilizer 22.4-24.1 g. |
