Abstract:

Zizhong County is a representative area for rice production in the hilly regions of Sichuan Province. Through years of technological integration and innovation, it has achieved a significant increase in rice yield per unit area. This paper systematically reviews the high-quality and high-yield rice cultivation technology system in Zizhong County, with a focus on key aspects such as variety selection, dry nursery seedling technology, “Dasanwei” intensive cultivation, scientific fertilization and irrigation, integrated pest management, and the “Five-Excellent Factors” integration model. It further examines the challenges faced in the process of technological integration and innovation, including high initial costs hindering large-scale adoption, uneven application and implementation rates of technologies, ecological risks arising from long-term monoculture, resource constraints and insufficient exploitation of potential. On this basis, the study proposes development strategies such as promoting the simplification and smart upgrading of technologies, advancing ecological and green low-carbon transformation, enhancing industrial integration and value chain development, and innovating management systems and service mechanisms. The technological practices in Zizhong County offer a replicable pathway for high-yield and high-quality rice cultivation in the hilly areas of Southern China, holding practical significance for ensuring regional food security.

Key words: rice, high-quality and high-yield cultivation techniques, dry nursery seedlings, five excellence factors integration

摘要：

资中县是四川省丘陵地区水稻生产的典型代表县，通过多年的技术集成与创新，实现了水稻单产的显著提高。本文系统梳理了资中县水稻优质高产种植技术体系，重点介绍了品种选育、旱育秧技术、“大三围”强化栽培、科学施肥与灌溉、病虫害综合防治以及“五良”融合模式等关键环节，并深入探讨了该县在技术集成与创新过程中所面临的挑战，包括前期投入高制约规模化推广、技术应用均衡性与到位率有待提高、长期单一种植带来的生态风险、资源禀赋限制及潜力挖掘不足等问题。在此基础上，提出推动技术轻简化与智慧化升级、促进生态化和绿色低碳转型、全面提升产业融合与价值链升级、创新经营制度与服务体系建设等发展对策。资中县的技术实践为西南丘陵地区水稻高产高效种植提供了可复制的路径，对保障区域粮食安全具有重要的实践意义。
