【摘要】 本研究在1987年—1989年大田对比试验的基础上,根据系统工程学“最佳模拟配合法”(The best modeling of approach)的原理,采用四因素二次正交回归旋转组合试验,选择播种量、种肥数量、播种方式、中耕次数作为栽培模式的决策变量,组建了旱地小麦栽培数学模型,确定了优化综合农艺措施组合方案,为实现早地小麦中产栽培提供了依据。更多还原

【Abstract】 On the basis of field contrast experiment in the years 1987～1989,based on theprinciple of the best modeling approach in systems engineering,this paperestablishes a mathematical model of wheat cultivation in dryland and determines the optimum comprehensive agronomy plan for combination.Using sowing,sced manure quatity,sowing pattern, Cultivation frequency as decision variable factors by way of quadratic regression whirling combination.This paper prodides basis for achieveing middle yield cultivation of wheat in dryland.更多还原
