摘要：
运用五元二次正交旋转组合设计,研究播期、密度、施氮量、施磷量、施钾量对油研599和三北98产量的影响；再用计算机进行模拟寻优,获得三北98产量200 kg/667 m2以上的栽培措施方案为:播期9月10日,密度6 274株/667 m2,施氮量14.64kg/667 m2,施磷量8.92 kg/667 m2,施钾量17.66kg/667 m2,平均产量为217.74kg/667 m2.油研599产量200kg/667m2以上的栽培措施方案为:播期9月10日,密度6 676株/667 m2,施氮量15.6 kg/667 m2,施磷量8.91 kg/667 m2,施钾量16 kg/667 m2,平均产量为238.17 kg/667m2.高产保优栽培对油菜品质性状影响的表现为含油率降低,种子蛋白质含量、油酸含量、亚油酸含量、亚麻酸含量、不饱和脂肪酸总量、油酸与亚油酸之和、饱和脂肪酸总量、不饱和指数增加,油的稳定性变差.%Effect of sowing date,density,as well as the amount of N,P20s and K2 0 on yields of two hybrid rape varieties,"Youyan599" and "Sanbei98" were investigated by five factors orthogonal rotational regression combination design.The optimal cultivation techniques for "Sanbei98" were as follows:sowing on september10,6676 plant/667 m2,15.6 kg/667 m2 N,8.919 kg/667 m2 P2O5,17.66 kg/667 m2 K2O,by which average yield of 217.74 kg/667 m2 may be obtained.To gain the yield higher than 200 kg/667 m2 for "Youyan599",the technique combination with sowing on september 10,6274 plants/667 m2 density,14.64 kg/667 m2 N,8.907 kg/667 m2 P2O5,and 16 kg/667 m2 K2O should be adopted,from which average yield of 238.17 kg/667 m2 was harvested.The cultivation measures for higher yield and quality might reduce the content and the stability of oil,while the contents of seed protein,oleic acid,linoleic acid,linolenic acid,unsaturated fatty acid,oleic acid and linoleic acid,saturated fatty acid,index of unsaturated fatty acid were elevated.
