福建省杂交水稻制种机械化关键技术集成与推广应用OA

Fujian Province is a top province in China for hybrid rice seed production,and full-process mechanization is an essential path for upgrading and improving the seed production industry.Currently,hybrid rice seed production in Fujian Province has basically achieved mechanization,with the comprehensive mechanization rate of plowing,planting,and harvesting exceeding 80％.However,it still faces challenges in certain aspects.On the basis of previous research,this paper summarizes key techniques for mechanization of hybrid rice seed production,including mechanized precision seed sowing and seedling raising,mechanized planting of the male parent and female parent,mechanized plant protection,mechanized removal of male parent plants,mechanized harvesting of the female parent,and high-efficiency mechanized seed drying.In addition,this paper systematically reviews the demonstration,promotion,and application of these techniques across the province and outlines strategies for future advancement,aiming to further improve the full-process mechanization level of hybrid rice seed production in Fujian Province and promote the high-quality development of the seed production industry.
