摘要
介绍了Ⅱ优633亲本的特征特性,结合3a制种实践,总结其高产制种技术应抓好几个环节:选好基地、确定抽穗扬花期和父母本播差期、培育多蘖壮秧、合理密植、加强肥水管理、科学赶粉、去杂保纯、适时收割等。
Characteristics of parents for new hybrid rice combination II You 633 was introduced and its high-yielding seed production techniques were summarized based on producing practice of 3 years.Several techniques were shown as follows：choosing good seed production base,determining heading stage and sowing time of parents,cultivating strong multiple-tillering seedlings,transplanting rational density,improving fertilizer and water management and scientific pollination,removing miscellaneous plants and harvesting timely.
