摘　　要：通过田间试验,研究了不同施氮量对油菜品种苏油8号产量与主要品质的影响。结果表明:随着施氮量的增加,油菜的单株一次有效分枝数、单株有效角果数、每角粒数、籽粒产量和产油量均呈先增加后降低的趋势;单株角果数和每角粒数对籽粒产量的影响较大;籽粒含油率和蛋白质含量随着施氮量的增加而降低。在该试验条件下,为获得较高产量和保证双低品质,苏油8号的适宜氮肥用量为325~352 kg/hm^2。The effects of different nitrogen application rates on the yield and main quality traits of oilseed rape new varietySuyou No. 8 were studied through field test. The results showed that：when nitrogen application rate increased,the number of effective primary branches per plant,number of effective pods per plant,number of grains per pod,grain yield and oil yield of Suyou No. 8 all increased first and then decreased;the number of pods per plant and the number of grains per pod had a greater influence on the grain yield;the oil content and protein content in oilseed rape grains decreased with the increase in nitrogen application rate. Under the conditions of this test,the suitable nitrogen application rate for the high yield and good quality of Suyou No. 8was 325～352 kg/ hm2 .
