优质两系杂交稻Y两优5866烟后高产制种技术

High-yielding Seed Production Techniques for Two-line Good Quality Hybrid Rice Combination Y Liangyou 5866 Planted as Post-tobacco Rice

介绍了优质两系杂交水稻Y两优5866亲本的特征特性,结合3 a制种实践,总结其烟后高产制种技术:合理安排父母本播种差期,培育多蘖壮秧、科学田管、综合防治病虫、创建父母本高产群体,科学喷施"九二○"、提高异交结实率,严格去杂去劣、确保种子质量等几个环节。

In this study, we introduced the parent,s characteristics of two-line good quality hybrid rice Y Liangyou 5866. At the same time, this paper also summarized the rice high-yielding seed production technology planted as post-tobacco rice, which contained reasonable arrangements for the parents of the sowing gap stage, cultivating more tillers seedlings, scientific field management, integrated pest management, create the parents of high yield population, scientific spraying “920”, improve the outcrossing rate, strictly to miscellaneous go bad, ensure the seed quality and so on several aspects.
