杂交水稻制种机械化关键技术集成与应用

Integration and Application in the Key Technologies of Mechanization of Hybrid Rice Seed Production

随着社会经济的发展和人民生活水平的提高,农村劳动力外出务工逐年增多,杂交水稻制种的生产成本不断攀升。介绍了国内外杂交水稻全程机械化制种技术的研究现状,分析了水稻机械化制种与常规制种生产技术的优势,提出了杂交水稻全程机械化制种的技术路线和关键环节技术,总结了母本机插秧育秧、机械插秧、无人机辅助授粉、种子收割和烘干等关键环节技术。

With the development of social economy and the improvement of people's living standard,more and more rural labor force goes out for work and the production cost of hybrid rice seed production continuously enhanced.In this research,we introduced the research status of whole-process mechanized seed production technology of hybrid rice at home and abroad,and analyzed the advantages of mechanized seed production and conventional seed production techniques for rice.The technical approach and the key techniques were put forward for the whole-process mechanized hybrid rice seed production.And the key technologies were summarized for transplanting seeding of female parent,transplanting seeding,UAV-assisted pollination and seed harvesting and drying.
