摘　　要：对优质油菜新品种苏油 1号进行密度、施肥量和肥料运筹配比的试验结果表明 :密度对产量高低影响最明显 ,其次是施肥量 ,肥料运筹配比对其影响较小。公顷产量 3 0 0 0kg以上 ,最经济、有效获得高产的栽培因子水平及组合是 ,密度 12万～16 .5万株 /hm2 ,施肥量 (纯氮 ) 2 70kg ,肥料运筹以基、苗、薹花肥 ,配比为 4∶2∶4。Field experiment was conducted to determine the effect of density,the amounts and proportion of fertilizer application on yield of Suyou No.1.Results showed that density was the main factor influencing the yield significantly among them.With yield of above 3000Kg/hm 2,the most suitable density of Suyou No.1 was 1.2-1.65×10 5plants/hm 2,the best amounts of fertilizer (pure N)was 270Kg/hm 2,and the suitable proportion of base-fertilizer,seedling-fertilizer and bolting-fertilizer was 4∶2∶4.
