豫北中产麦区小麦高产优质优化农艺措施研究

A Study on Agronomic Measures for High Yield and Quality of Winter Wheat in Middle-Yield Wheat Fields in the Area of Northern Henan

采用二次正交旋转回归组合设计田间试验测得的参数,建立了以产量、蛋白质含量、赖氨酸含量为目标的数学模型,通过模拟仿真筛选出豫北中产麦区小麦亩产>350kg、蛋白质含量>18%、赖氨酸含量>0.42%的综合栽培技术优化方案为:亩施纯氮18.1～19.5kg,P_2O_55.7～8.3kg,每亩播量7.2～8.4kg.

According to the parameters obtained from field experiment based on the quadratic orthogonal revolving regression combination design,the mathematic model aiming at output, protein content and Lysine content has established. Through simulation and selection by computer,the optimum plan of mud-cultivation technique has obtained for achiving more than 350kg output permu,18% protein content and 0. 42% Lysine content. The plan included applying pure N 18. 1~19. 5 kg,P2055. 7~8. 3 kg and sowing seed 7. 2~8.4 kg per mu .
