【摘要】 选用播期、播量、氮磷复合肥、精制有机肥4个小麦主要栽培因素进行多元二次正交旋转回归组合设计试验,建立了以产量指标为目标的数学模型,并对模型进行了全面系统的分析,在探讨数学模型整体结构的基础上,根据不同的栽培条件筛选出不同的栽培方案。更多还原

【Abstract】 In the paper, using sowing date, seeding rate, nitrogen and phosphorus compound fertilizer, refined organic fertilizer four main wheat cultivation factors of multiple two rotation regression orthogonal combination design and a mathematical model to yield index as the target were established and comprehensive analysis was systematically conducted for the model. Based on the study of mathematics the whole model structure, different cultivation scheme were selected.更多还原
