豫北小麦产量、品质综合栽培措施的回归分析与优化

The Regression Analysis and the Optimum Schemes for Wheat Grain Yield and Quality in the Comprehensive Cultivation Measures in the North of Henan

运用四元二次正交旋转回归组合设计,以底施氮肥、底施磷肥、追施氮肥和播种量为试验因子,建立了这些因子对小麦产量、蛋白质含量、赖氨酸含量、面筋含量的回归方程,分析了因子对产量、蛋白质含量、面筋含量的主效和交互作用,模拟确定了产量440公斤/亩、蛋白质含量16.5％赖氨酸含量0.42％、面筋含量50.5％的栽培措施方案是:底施尿素15.93—19.28公斤/亩,底施钙镁磷肥36.55—51.28公斤/亩,追施尿素13.99—26.26公斤/亩,播种量7.46—7.70公斤/亩。

Applying the combination design of a quadrotic, orthogonal and pivoting regression for four factors, the regression equations yield, protein content, lysine content and gluten contentwith nitrogen as base fertilizer, phosphorus as base fertilizer, nitrogen as topdressing fertilizer, and sowing quantity have been established. The simple and alternate effects for these factors to yield, protein content and gluten content have been analysed. 625 schemes of yield, protein ontent, lysine content and glutent content have been imitated. The scheme of grain yield at 440 kg/mu, protein content at 16.5%, lysine content at 0.42%, and gluten content at 10. 5%, is nitrogen as base fertilizer 15.93-19.28kg/mu,phosphorus as base fertilizer 36. 51-51. 28kg/mu, nitrogen as topdressing fertilizer 13.99-16.20kg/mu and sowing quantity 7. 46-7.70kg/mu.
