摘要
本文提出了在花期相遇的前提下,改进制种技术,适当扩大行比,增加每亩母本有效穗数,加强人工辅助授粉提高结实率,是获取制种高产的关键。
This paper reports the agronomic practices for producing high yield and improving seed production techniques by hybrid rice. Field trial showed that incneasing the row ratio of mate snal and paternal lines, the number of fertile panicle and the Crossing rate by Supplementary pollination are the key effective measures.
