| 摘 要： | 研究了施氮量 (x1 )、施磷量 (x2 )、施硼量 (x3)、密度 (x4 )和父母本行比 (x5)对优质杂交油菜制种产量的影响。结果表明 :对制种产量影响最大的因子是施氮量和父母本行比 ,各因子对产量的贡献大小依次为 :x1 >x5>x4 >x3>x2 ;各因子间的互作效应不显著。运用频数分析法在计算机上模拟寻优 ,得出优质双低杂交油菜制种产量达到 90 0kg/hm2 以上的综合农艺措施 :施氮量 99.95～ 10 1.74kg/hm2 ,施磷量 66.2 1～ 87.10kg/hm2 ,施硼量 2 5 .80～ 2 8.5 0kg/hm2 ,密度 2 0 .3 9万～ 2 2 .2 4万株 /hm2 ,父母本行比 2∶2～ 2∶3。

| Abstract: | The experiment in the function of five factors to the ontput of seed-production of double-low hybrid rape:N(x_1),P_2O_5(x_2),boron(x_3),plant density(x_4) and ratio of rows of sterile and restorer lines(x_5) was conducted.The result showed that N and row ratio were more important.The sequence of importance is x_1>x_5>x_4>x_3>x_2.By using freqnency analysis method,simulating to search for excellent planton in the computer,the high yield seed-making optimization model of 900kg/hm~2 was established :N99.95～101.74kg/hm~2, P_2O_566.21～87.10kg/hm~2,boron25.80～28.50kg/hm~2,density 20.39～22.24 ten thousand/hm~2,row ratio 2∶2～2∶3. |
