我們在1964年从广东省农科院引进“二九矮4号”少量种子,进行加速繁殖。由于二九矮4号是广东省的中熟早稻,在黄岩栽培要立秋才能成熟,无法进行倒种春栽培。因此,我們早季采用分株繁殖,然后再培育再生稻。結果以2,300多粒种子进行繁殖,早季收了613.7斤,晚季收了453斤,一年中共获 In 1964, we introduced a small amount of seeds of “No. 19 Dwarf No. 4” from Guangdong Provincial Academy of Agricultural Sciences for accelerated breeding. As the No. 19 dwarf maturing early maturing rice in Guangdong Province, Huangyan was cultivated to stand in the autumn to mature and could not be planted in spring. Therefore, we use ramets breeding in the early season, and then cultivate ratooning rice. Results More than 2,300 seeds were bred for 613.7 kg in early season and 453 kg in late season.
