西南丘陵地区水稻优质高产种植技术集成与创新OA

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.
