摘　　要：以3个杂交节水抗旱不育系和2个恢复系为材料,在幼穗分化初期设置尿素(N)、多效唑(MET)、二甲四氯(MCPA)和磷酸二氢钾(K)的不同施用量处理,研究各生长调节物质对亲本幼穗发育、抽穗期和成穗数变化的影响,并探讨了几种花期调节措施的运用方法,为节水抗旱杂交稻制种提供参照。In order to study the flowering adjustment technology on parents of the water-saving and drought resistant hybrid rice, with three CMS lines and two restorer lines as materials, the experiment was carried under the early stage of differentiation of rice panicle with 4 flowering adjustment substance： Urea（N）, Paclobutrazol（MET）, MCPA, and Potassium dihydrogen phosphate（K）. To explore the flowering adjustment technology and provide beneficial help for water-saving drought resistant hybrid rice seed production.
