摘　　要：提高杂交稻制种产量是降低水稻种子生产成本、加速杂交稻推广的有效途径之一。试验选用杂交粳稻"秋优金丰"亲本-R44和秋丰A为材料,对两亲本的生育特性和开花习性进行观察,开展了一系列杂交粳稻"秋优金丰"相关制种技术和栽培技术的研究。结果表明,采用机插秧、割叶处理、适宜的肥水,以及"920"农药对制种亲本的穗位差和花期的调节等处理有利于杂交制种产量的提高。这为该品种的大面积推广提供相应的技术支持。Seed yield improvement of hybrid rice is an effective way to reduce costs and accelerate the promotion of hybrid rice.Hybrid rice＂Qiuyoujinfeng＂parent-＂R44＂and ＂Qiufeng A＂were applied to investigate the growth and flowering characteristics of two parents,and a series of seed-related and cultivation-related technique of hybrid rice＂Qiuyoujinfeng＂.The result showed that mechanical planting technology,cutting leaves,appropriate fertilizer,and ＂920＂ pesticide can prominently regulate the height and flower stages of the two parents,and increase the yield of hybrid seed,which can provide the technical support for large scale promotion of hybrid rice＂Qiuyoujinfeng＂.
