摘　　要：采用三因素二次回归正交旋转组合设计试验,建立了萝卜新品种万萝一号产量(Y)与播期(X1)、密度(X2)和施氮量(X3)间的数学模型。经因子水平选优,得出产量在2500kg/667m2下的栽培模式:播期在9月13—14日,密度4491.3～5108.7株/667m2,施氮量6.11～7.69kg/667m2。The mathematical model for the relationship between the yield of hybrid radish(Raphanus sativus L.)Wanluo 1 and seeding time and planting density and application amount of N was established by means of quadratic orthogonal regressive rotation combination designed with three factors and five levels, The optimal cultivation methods for yield 2 500 kg/667 m2 was that the seeding time should be in September 13-14 and the density should be 4 491.3～5 108.7 plants/667 m2 and nitrogen should be 6.11～7.69 kg/667 m2,according to the mathematical model.
