汉中市水稻大面积提产增效技术路径
Technology Pathways for Large-Scale Yield Increase and Efficiency Improvement of Rice in Hanzhong City
摘要
Abstract
To thoroughly implement the national food security strategy and operationalize the general requirements of"storing grain in the land and storing grain through technology",this study focuses on Hanzhong City to address bottlenecks in raising rice yields and insufficient technological integration in southern Shaanxi.Anchored in regional ecological characteristics and the rice-rapeseed rotation system,we systematically explored technical pathways for large-scale rice yield improvement,emphasizing the coordinated enhancement of both productivity and economic returns.By selecting superior varieties and integrating cultivation techniques such as robust seedling cultivation combined with dense mechanical transplanting,we established a comprehensive yield-increasing and efficiency-enhancing pathway encompassing"variety optimization+technological integration+model innovation+contract farming+demonstration-driven promotion".This pathway was promoted through a multi-level demonstration network.In 2025,despite multiple adverse weather events,the average rice yield in Hanzhong reached 479.57 kg/667 m2,an increase of 8.47 kg/667 m2 over the previous year(year-on-year growth of 1.80%).Notably,the mechanized transplanting mode using the leading variety Huazheyou 210 increased yield by 37.30 kg/667 m2 compared with the manual transplanting mode,with a corresponding profit gain of 150.10 yuan/667 m2.The developed technical model demonstrates strong resilience and high regional adaptability,providing a replicable and scalable systematic solution for sustained rice yield improvement and whole-industry-chain value enhancement in southern Shaanxi.关键词
