杂交水稻全程机械化制种技术研究初步进展

Preliminary Progress in the Research on Whole-process Mechanization Technology of Hybrid Rice Seed Production

根据稻作农业机械的发展现状,提出了杂交水稻全程机械化制种的技术路线、关键技术、农机装备和基础条件,总结了母本机插秧、母本机械穴直播、种子机械烘干和无人直升机辅助授粉及喷施赤霉素等关键环节技术的试验研究进展,分析了实施全程机械化制种的经济、社会及生态效益。

Based on the existing agricultural machinery available for rice production, the technical approach, key techniques, requirements for agricultural machines and essential conditions were put forward for the wholeprocess mechanized hybrid rice seed production. The research progress was introduced in the key techniques including mechanized hill seeding of female parent, mechanized transplanting of female parent, supplementary pollination and GA3 spraying by unmanned helicopter, and mechanical drying of seed. The economical, social and ecological bene fits were also analyzed in the wholeprocess mechanized hybrid rice seed production.
