摘要：

为了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，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。结果表明，‘油研599’获得最高产量指标（2898.211 kg/hm2）时的各个因素组合为活棵肥89.27 kg/hm2，开盘肥120 kg/hm2，腊肥101.12 kg/hm2，施氮总量为310.39 kg/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（2870.14 kg/hm2）时的各个因素组合为活棵肥120 kg/hm2，开盘肥120 kg/hm2，腊肥37.55 kg/hm2，施氮总量为277.55 kg/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（2813.82 kg/hm2）时的各个因素组合为活棵肥120 kg/hm2，开盘肥120 kg/hm2，腊肥76.23 kg/hm2，施氮总量为316.23 kg/hm2，活棵肥、开盘肥、腊肥所占比例分别为37.95%、37.95%、24.11%。

Abstract:

In order to study on yield of high grade hybridized rapeseed and operation model of nitrogen fertilizer in Brassica napus L. Experiment material was ‘Youyan 599’ and ‘SanBei 98’, study on effects of different applied time of nitrogen fertilizer on yield of high grade hybridized rapeseed were carried out through quadratic regression orthogonal gyration combination design in Brassica napus L. The results showed that: factor combination when ‘Youyan 599’ obtained maximum yield target was living rape fertilizer 89.27 kg/hm2, opening fertilizer 120 kg/hm2, 12th lunar month fertilizer 101.12 kg/hm2, total applied amount of nitrogen fertilizer was 310.39 kg/hm2, the percent of living rape fertilizer, opening fertilizer, 12th lunar month fertilizer were 28.76%, 38.66%, 32.58%, respectively. Factor combination when ‘SanBei 98’ obtained maximum yield target was living rape fertilizer 120 kg/hm2, opening fertilizer 120 kg/hm2, 12th lunar month fertilizer 37.55 kg/hm2, total applied amount of nitrogen fertilizer was 277.55 kg/hm2, the percent of living rape fertilizer, opening fertilizer, 12th lunar month fertilizer were 43.24%, 43.24%, 13.53%, respectively. Factor combination after two varieties were merged were living rape fertilizer 120 kg/hm2, opening fertilizer 120 kg/hm2, 12th lunar month fertilizer 76.23 kg/hm2, total applied amount of nitrogen fertilizer was 316.23 kg/hm2, the percent of living rape fertilizer, opening fertilizer, 12th lunar month fertilizer were 37.95%, 37.95%, 24.11%, respectively.
