摘　　要：杂交稻单本密植大苗机插栽培技术的研发解决了传统机插杂交稻用种量大、秧龄期短、秧苗素质差、双季稻品种不配套等生产问题。本文对2017—2021年杂交稻单本密植大苗机插栽培技术在衡阳的推广应用情况进行了总结,重点阐述了杂交稻单本密植大苗机插栽培技术在衡阳的推广模式和应用成效,提出了促进杂交稻单本密植大苗机插栽培技术在衡阳推广应用的对策。The development of cultivation technology for mechanically dense transplanting of large single seedlings of hybrid rice had solved the production problems of traditionally machine-transplanted hybrid rice,including high seeding rate,short seedling age,poor seedling quality,and unmatched growth duration for double-season varieties.In this paper,we summarized the extension situation of cultivation technology for mechanically dense transplanting of large single seedlings of hybrid rice in Hengyang from 2017 to 2021.In particular,we focused on the extension mode and benefits of cultivation technology for mechanically dense transplanting of large single seedlings of hybrid rice in Hengyang,and put forward the countermeasures to promote the application of cultivation technology for mechanically dense transplanting of large single seedlings of hybrid rice in Hengyang.
