摘　　要：研究不同密度对油莱品种华油杂62农艺性状及产量的影响。结果表明：在鄂北地区，华油杂62的直播适宜密度为30万～45万株／hm2。在30万株／hm2密度条件下，产量最高可达3691．5kg／hm2，但各农艺性状值并不是最高值。因此，合理密植，充分发挥个体生产潜力。是获取高产的关键。Effects of different planting density on yield and agronomic traits of Huayouza 62 were studied. The results indicated that in north- ern Hubei, the optimal density of Huayouza 62 is 300 000 to 450 000 plants per hm2 , under this planting density, the highest rapeseed yield could reach to 3 691.5 kg/hm2 , but the agronomic character is not the best, therefore, reasonable density, give full play to individual produc- tion potential, is the key to obtain high yield.
