摘要:

杂交水稻为保障我国乃至世界粮食安全做出了重大贡献。目前我国杂交水稻种植面积呈下降趋势,究其原因,主要是较高的用种成本限制了其可持续发展。传统的杂交水稻种子生产方式已难以满足当前水稻轻简化栽培的需求,实现杂交水稻种子由劳动密集型生产方式向机械化生产方式转型是降低制种成本的一条理想途径。本文对杂交水稻机械化制种的研究进展进行了综述,分析了杂交水稻机械化制种面临的难题,结合多年的研究实践,提出了解决杂交水稻机械化制种难题的技术途径,并对杂交水稻机械化制种的发展前景进行了展望。

Abstract:

Hybrid rice has made great contributions to the food security of China and even the world. But the planting area of hybrid rice in China is declining, the main reason is that the higher cost of seeds restricts the sustainable development of hybrid rice. The traditional production method of hybrid rice seeds has been difficult to meet the current needs of light and simplified rice cultivation. The transformation of hybrid rice seed production from labor-intensive to mechanized seed production is an ideal way to reduce the cost of seed production. This paper summarized the research progress of mechanized seed production of hybrid rice, analyzed the problems faced by mechanized seed production, put forward the technical ways to solve the problems of hybrid rice mechanized seed production combined with the research practice for many years, and prospected the development prospect of mechanized seed production of hybrid rice in the future.

Key words: hybrid rice, mechanized seed production, technical approach
