摘要
根据两系杂交中稻培两优537双亲的特征特性,结合湖北的气候特点,研究并提出了选好制种基地、确定双亲的最佳抽穗扬花期和播差期、培育多蘖壮秧、设置合理的行比、插足基本苗、加强肥水管理、建立高产群体、搞好花期预测和调控、巧施“920”、提高授粉质量、严把种子质量关等制种技术措施。
According to the characteristics of male and female parents of Pei-liang-you 537 and the climate conditions of Hubei province,the key of the Pei-liang-you 537 seed production was summarized.The main experiences were included as follows： well-arranging seeding time interval of the male and female parents,raising healthy tillered seedlings,suitable density cultivation,better managing water and fertilizer,constructing high yield group, forcasting and regulating the flowering period in time,spraying ＂920＂ techiniquely,improving pollination quality, strictly controling the seed quality.
