【摘要】 本文运用二次回归正交旋转组合设计田间试验测得的数据,建立以亩产量、纯收入、籽粒蛋白质含量、赖氨酸含量为目标函数的回归模型,通过计算机模拟寻优,筛选出了亩产375kg以上、纯收入250元以上、籽粒蛋白质含量15%以上、赖氨酸含量0.42%以上的最佳农艺组合方案为:10月2～3日播种,每亩基本苗14.2～16.3万,底施尿素17.4～17.8kg,过磷酸钙35.7～37.9kg,中耕2次.因子主次分析表明,增施氮、磷底肥,注意中耕保墒,是旱地小麦高产优质的关健措施.更多还原

【Abstract】 According to the parameters obtained from field experiment based on quadratic regression-orthogonal-revolving combination design,has been established the regression model including aim functions such as yield per mu ,pure income,protein content of grainand lysine content. Through the simulation and optimum selection by computer,the best agronomic combination plan has been selected for achiving more than 375kg yield permu and 250 Yuan net income and 15% protein content of grain and 0. 42% lysine content. The plan includes these factors such as sowing date on October 2nd - 3rd, basic seedling aboutl42000~163000,17. 4-17. 8kg Urea and 35. 7 - 37. 9kg Cacium superphosphate permu as base fertilizer and twice intertillage. Based on the analysis of all factors, the crucial measuresfor high yield and quality of winter wheat were to apply base fertilizer of nitrogen andphosphate and pay attention to intertillage and soil moisture.更多还原
