摘　　要：采用二因素二次回归正交旋转组合设计试验,建立了油菜新品种绵油13号产量(Y)与种植密度(x1)和施纯氮量(x2)间的数学模型。经因子水平选优,得出产量在2700 00～3058 97kg/hm2间的栽培模式:种植密度15 75～28 14万株/hm2,施纯氮量116 35～266 56kg/hm2。The mathematical model for the relation between the yield of high erucic acid rape (B.napus L.)Mianyou 13 and planting density and application amount of N was established by means of quadratic orthogonal regressive rotation combination design with two factors and five levels.The optimal cultural methods for yield between 2700kg/ha and 3058.97kg/ha,according to the mathematical model,were that the density should be 157 500-281 400 plants/ha and the application amount of N should be 116.35-266.56kg/ha.
