本文系统总结了水稻品种Y两优1173的综合栽培技术,并对其2024年在广东兴宁的示范种植表现进行了评估。其综合栽培技术包括超声波选种与强氯精浸种催芽;采用塑盘育秧配合壮秧剂培育健壮秧苗;实施精细整田与合理密植(25.5万~30.0万蔸/hm2);推行精准与干湿交替的节水灌溉策略;贯彻“预防为主、综合防治”理念,构建以健身栽培为基础,结合精准测报、理化诱控与科学用药的绿色防控模式,并应用植保无人机提升防治效率;黄熟末期机械收获,烘干至稻谷含水量14.5%时安全储藏。示范结果显示,该品种全生育期112~126 d,有效穗数249万~261万穗/hm²,产量9 543.30~9 769.50 kg/hm²,垩白度1.2%~2.5%,整体表现出高产、优质、熟色佳及抗性强等优良特性。本文为该品种在相似生态区推广种植提供参考。

The comprehensive cultivation techniques for the hybrid rice variety Y Liangyou 1173 were systematically summarized, and its performance in a demonstration planting conducted in Xingning, Guangdong, in 2024 was evaluated. The comprehensive cultivation techniques include ultrasonic seed selection and seed soaking and germination with strong chlorine-based disinfectant; using plastic tray seedling raising combined with seedling strengthening agent to cultivate robust seedlings. Additionally, the methods involve fine land preparation and rational dense planting (255 000-300 000 hills/hm2), the implementation of precise and alternating dry and wet water-saving irrigation strategies, and the adherence to the “prevention first, integrated control” philosophy. A green pest and disease control model was established, based on healthy cultivation practices and incorporating accurate forecasting, physical and chemical attraction control, and scientific pesticide application, with the use of plant protection drones to enhance control efficiency. Mechanical harvesting in the late stage of ripening, safe storage when dried to a moisture content of 14.5% in rice grains. The demonstration results showed that the variety had a total growth period of 112-126 days, effective panicle numbers of 2.49-2.61 million panicles/hm2, and a yield of 9 543.30-9 769.50 kg/hm2. The chalkiness degree ranged from 1.2% to 2.5%. Overall, the variety exhibited excellent characteristics such as high yield, high quality, desirable maturity color, and strong resistance. This study provides a reference for the promotion and cultivation of this variety in similar ecological regions.
