[目的]研究西巨胚1号品种特性及在攀西高原稻区高产栽培技术.[方法]通过对西巨胚1号、合系22-2、昌米011在生育期、农艺性状、分蘖力、穗部性状和品质性状等方面进行对比分析,从播期、播量、栽插密度、水肥管理、病虫害防治等方面总结西巨胚1号在攀西高原稻区栽培技术要点.[结果]西巨胚1号在攀西高原稻区种植中表现出胚大、米质较优、抗病、抗倒、适应性强等特点.适宜在攀西高原地区3月下旬播种,用种量为60～75 kg/hm<'2>,基本苗120万～150万株/hm<'2>,早施分蘖肥,重施基肥,补施穗粒肥,科学灌水,注意病、虫、草、鸟害防治.[结论]该研究为进一步改进西巨胚1号栽培技术提供理论和生产实践参考.%[ Objective ] The paper was to study the variety characteristics of Giant Embryo No. 1 Japonica Rice and its high yield cultivation techniques in Panxi plateau rice region. [ Method ] Giant Embryo No. 1, Hexi 22-2 and Changmi 011 were compared and analyzed from the aspects of growth stage,agronomic traits,tillering ability,panicle and quality traits,and the cultivation techniques of Giant Embryo No. 1 in Panxi plateau rice region were summarized in the aspects of sowing time, sowing rate, planting density, water and fertilizer management and pest and disease control. [ Result ] Giant Embryo No. 1 showed the characteristics of big embryos, excellent grain quality, disease resistance, lodging resistance and strong adaptability in the cultivation in Panxi plateau rice region,which was suitable for sowing in late March in the region. The seed rate was 60 -75 kg/hm2 ,basic seedlings were 1 200 000 - 1 500 000/hm2 with early application of tillering fertilizer and heavy application of base fertilizer,grain fertidizer should also be supplemented with scientific irrigation,and diseases,insects,grass,bird damage should be paid attention. [ Conclusion ] The study provided the reference for theoretical and production practices for further improvement of Giant Embryo No. 1 cultivation techniques.
