摘要
对双低杂交油菜制种的适宜播期、父母本行比及前期施肥方式进行了研究.结果表明:适播期为9月16～25日;父母本行比以2:3为宜;前期采用平衡配方施肥可使制种产量提高11.5%,在此基础上,增施种肥(磷肥)有进一步的增产效果,可使制种产量提高18.7%.
Studies on the suitable sowing time, parental row ratio and the fertilization way for seed-making of double-low hybrid rapeseed, show that the appropriate sowing time is from Sep. 16 to 25, the suitable row ratio is 2：3 and using balance fertilization can increase seed-making yield by 11.5 %. On this base adding base fertilizer P2O5 can increase the seed-making yield by 18.7%.
