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 11号产量与种植密度和施纯氮量间的数学模型。经因子水平选优 ,得出产量在 30 0 0 .0 0~ 314 0 .6 9kg/hm2 间的栽培模式 :种植密度 2 0 .5 0~ 2 2 .89万株 /hm2 ,施纯氮量 197.83~ 2 32 .2 1kg/hm2 。
The mathematical model for the relation between the yield of hybrid rape(B.napus) Mianyou No.11 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 3000.00 kg/hm 2 and 3140.69 kg/hm 2, according to the mathematical model ,were that the density should be 205000~228900 plants/hm 2 and the application amount of N should be 197.83~232.21 kg/hm 2.
