摘要
以双低油菜新品种‘沪油21'为材料,在直播条件下,研究了不同氮肥施用量、氮肥配比和硼肥对其产量构成因子及产量的影响。结果表明:‘沪油21'氮肥最佳施用量为270 kg/hm^2;当氮肥施用量为270 kg/hm^2时,年后氮肥施用比例应为25%-30%;施用硼肥对油菜籽产量无显著影响。
Effect of different amount of nitrogen fertilizer,nitrogen fertilizer proportion and boron fertilizer on yield components and yield were studied under direct seeding condition taking the double low rape new variety ‘Huyou 21’as material.The results showed that the optimum amount of N fertil-izer was 270 k/hm2 ,and nitrogen ratio for bolting should be 25%-30%.Application of boron fertil-izer had no significant effect on rapeseed yield.
