通过大田实验，研究了不同种植密度和施氮量对特高芥酸油菜品种309产量和品质的影响。结果表明：种植密度对每角粒数影响显著，对产量及其他指标的影响均不显著；施氮量对产量、千粒重、花生烯酸含量、含油率影响显著，对其余指标的影响均不显著；在本试验条件下，309的最适种植密度为52．5万/hm2，最适施氮量为180 kg/hm2，此时籽粒产量最高，籽粒芥酸含量较高，其他品质指标表现也较优。

Through field tests , we studied the effects of different planting densities and nitrogen application rates on the yield and quality of super-high-erucic-acid rapeseed variety “309”.The results revealed that planting density had significant effect on the seed number per pod of rapeseed , but had no significant effects on yield and other indexes .The application rate of nitrogen had significant effects on yield , 1000-grain weight , arachidonic acid content and oil content , while it had no significant effects on other indexes .Under the conditions of this test , the optimum planting density of “309” was 525000 plant/hm2 , and the optimum application rate of nitrogen was 180 kg/hm2 .Under the above optimum conditions , the seed yield of “309” was the highest , the content of erucic acid in seeds was higher , and other quality indexes were also better .
