摘　　要：湘两优900(超优千号)是袁隆平院士团队最新培育的两系超级稻新组合,该组合株叶形态理想,根系发达,熟期适中,具有穗大粒多、结实率高、高产稳产等特点。2019年湘两优900在四川省德昌县进行百亩片超高产攻关示范,平均单产达16.35 t/hm^2。本文介绍了湘两优900的特征特性,单产16.35 t/hm^2的超高产栽培技术,并提出了进一步提高产量潜力的措施。Xiangliangyou 900 is a two-line hybrid rice combination bred by Yuan Longping team. It has the characteristics of ideal plant type, developed root system, suitable growth duration, large panicles with plenty of spikelets, high seed setting rate and high and stable yield, etc. In 2009, the super-high yield cultivation demonstration was carried out in Dechang county, and the average yield was 16.35 t/hm^2. In this paper, the characteristics of Xiangliangyou 900 were introduced and the high-yielding cultivation techniques with yield 16.35 t/hm^2 were described in detail, including rational fertilization, scientific water management, pest and disease control,and proposed measures to increase the yield potential.
