摘　　要：为了探索小麦洲元9369在新乡地区高产高效优质的栽培技术,试验采用不同播量、追肥时期和多效唑处理,研究其对洲元9369产量和品质的影响。结果表明:洲元9369在新乡试验田环境下,以187.5 kg/hm^2的播量处理下产量最高,再提高播量,产量不增反降;氮肥适当后移处理可以在保证产量稳定的情况下,提高加工品质;多效唑处理可以控制株高,降低倒伏风险,但对参试品种的产量和品质均造成不同程度的影响,不建议在生产中广泛使用。In order to develop high yield, good quality and benefits culture technique of Zhouyuan 9369 in Xinxiang, Henan Province,different seeding quantity, topdressing and paclobutrazol treatments were conducted to study the effects of these factors on yield and quality of Zhouyuan 9369. The results showed that the yield was the highest in 187.5 kilograms per hm2. On the other hand, the quality of Zhouyuan 9369 rose with the treatment of appropriate later fertilizing. The results showed that paclobutrazol could effectively shorten plant height, but at the same time, the yield reduced. So, the widely used of paclobutrazol in production is not recommended.
