AbstractThe comprehensive cultivation techniques for the hybrid rice variety Y Liangyou 1173 were systematicallysummarized，and itsperformance inademonstrationplantingconducted in Xingning，Guangdong，in 2024 was evaluated.The comprehensive cultivation techniques include ultrasonic seed selection and seed soaking and germination with strongchlorine-based disinfectant；using plastictrayseedling raising combined with seedling strengthening agent to cultivate robustseedlings.Additionaly，the methods involve fineland preparation andrational dense planting（255OO0-30o Ooo hils/hm2），the implementation of precise and alternating dryand wet water-saving irigationstrategies，andtheadherence tothe“prevention first，integrated control"philosophy.A greenpestanddisease control model was established，based on healthycultivation practicesand incorporating accurate forecasting，physical and chemicalatractioncontrol，andsientific pesticideapplication，withtheuseof plantprotectiondrones toenhance control effciency.Mechanical harvesting in the late stage ofripening，safe storage when dried toa moisture contentof （2 14.5% in rice grains.The demonstration results showed that the variety had a total growth period of112-126 days， effective panicle numbers of 2.49-2.61 million panicles/hm²，and a yield of 9543.30-9769.50kg/hm2 .The chalkiness degreeranged from 1.2% to 2.5% .Overall，thevarietyexhibited excellent characteristics such ashighyield，high quality，desirable maturitycolor，and strong resistance.This study provides areferenceforthe promotion and cultivation of this variety in similar ecological regions.
