摘要
介绍了恒优178亲本的特征特性,结合3 a制种实践,总结其高产制种应抓好: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、科学管理肥水、及早喷施"九二○"、人工辅助授粉,去杂保纯,适时收割等几个环节。
In this study, we introduced the parent,s characteristics of Hengyou 178. At the same time, this paper also summarized the rice high-yielding seed production technology, which contained chosen base, determine the heading stage, cultivating more tillers seedlings, scientific management, reasonable density, probable sowing phase difference, cultivating seedlings, increased maternal transplanting density, highyielding seedlings and auxiliary measures.
