摘      要：[目的]研究甘蓝型优质杂交油菜获得高产的施氮量和氮肥运筹模式。[方法]以‘油研599’和‘三北98’为材料,采用三元二次通用正交旋转组合设计方法,对不同时期施氮量对油菜产量的影响进行研究。[结果‘]油研599’获得最高产量指标(2898.211kg/hm2)时的各个因素组合为活棵肥89.27kg/hm2,开盘肥120kg/hm2,腊肥101.12kg/hm2,施氮总量为310.39kg/hm2。活棵肥、开盘肥、腊肥所占比例分别为28.76%、38.66%、32.58%‘;三北98’获得最高产量指标(2870.14kg/hm2)时的各个因素组合为活棵肥120kg/hm2,开盘肥120kg/hm2,腊肥37.55kg/hm2,施氮总量为277.55kg/hm2,活棵肥、开盘肥、腊肥所占比例分别为43.24%、43.24%、13.53%。2个品种合并后获得最高产量指标(2813.82kg/hm2)时的各个因素组合为活棵肥120kg/hm2,开盘肥120kg/hm2,腊肥76.23kg/hm2,施氮总量为316.23kg/hm2,活棵肥、开盘肥、腊肥所占比例分别为37.95%、37.95%、24.11%。[结论]该研究为优质杂交油菜的高产栽培提供理论依据。
