二次回归正交组合设计在小麦高产栽培中的应用

The Application of Design of Secondary Regression and Orthogonal Combination to High-Yield Cultivation of Wheat

本文是＂洛阳偃师市＇豫麦１８号＇高产栽培专家系统＂基础研究的一部分．探讨＂豫麦１８号＂高产栽培技术的最佳生产条件．采用二次回归正交组合设计，找出了＂豫麦１８号＂最高产量和产量在４８０ｋｇ以上的最优组合方案和关键农艺措施，使得＂豫麦１８号＂这一优良小麦品种的高产栽培技术得到了理论上的论证．

Apart of basic research for the expert System of high-yield cultivation of no. HW18 in Yanshi is given. The best Production Condition of its high-yield cultivating technique is discussed.Adopting the design of Secondary regnession and orthogonal combination, the best combination method of output-above 480 kg and the key agronomic technique is obtained. This theory is proved.
