摘要
2015~2016年，在甘肃、湖南两省进行绿肥新品种油肥1号繁种生产试验，研究了延迟播种期和不同密度对繁种产量的影响，建立了油肥1号高产繁种技术体系。结果表明，该品种在甘肃北方春油菜区可正常结实，密度为60万株/hm2时产量最高，达3303.32kg/hm2，各项经济性状指标与当地常规油菜无明显差异，发育进程略早于青油14号；在湖南冬油菜区将播种期延迟至10月底也可正常结实，但产量较低。
Based on seed-breeding production tests in Gansu and Hunan Provinces from 2015 to 2016, the effects of later seed-sowing and different densities on the final yield studied, and a system for high-yield seed-breeding technology for Youfei No. 1 was established . The results demonstrated that in Gansu Province, part of northern spring-rapeseed region, this cultivar had a normal seed formation, reaching the highest yield of 3303.32 kg when plantation density was 600 000 per hm2, but no differences were found among a series economic properties compared to local conventional varieties, and the developmental process of this cultivar was a bit earlier than Qingyou No. 14;while in Hunan Province, although still formed seed normally when the sowing dates postponed to late October, only low yield could be obtained.
