Based on the geographical characteristics and rice cultivation practices in Yuexi County, Anhui Province, the high quality, high yield, and green efficiency cultivation techniques were summarized. These include selecting certified high quality, multi resistant varieties adapted to local climate conditions, such as Weiliangyou 8612 and Tianyouhuazhan; sowing around April 20, with appropriately earlier dates for high-altitude areas; ensuring robust seedlings through sun-drying and disinfection of seeds, application of “farewell pesticides”, and standardized seedling cultivation; determining row and plant spacing for mechanical or manual transplanting based on variety and panicle type, with hybrid rice density controlled at 210 000-270 000 hills/hm2; promoting organic fertilizer substitution and soil testing based on formulated fertilization, controlling nitrogen application, and implementing water-saving irrigation techniques such as shallow water irrigation and timely field drying; adopting integrated pest management measures combining agricultural, biological, and physical-chemical control methods (planting insect attracting and flowering plants, hanging insect attracting boards, etc.), with scientific pesticide application focusing on key targets like rice blast (tricyclazole, isoprothiolane) and planthopper (triflumezopyrim, nitenpyram·pymetrozine); emphasizing “early and small” weed control through integrated management combined with farming practices, and enhancing monitoring and physical protection against wild boar damage; and performing mechanical harvesting at the early yellow maturity stage, coupled with low-temperature drying technology to ensure grain quality. This integrated technical system optimizes key processes and provides references for high quality, high yield rice cultivation in related regions.
