1987年,我们在青山乡荔江制种点制种502.6亩,经验收统计,总产9.32万公斤,平均亩产185.6公斤,比这个点1986年平均亩产增产26.1％。其中(?)优桂33制种面积71.1亩,平均亩产240.1公斤;汕优桂33面积244.4亩,亩产179.4公斤;汕优桂34面积187.1亩,亩产172.0公斤,创造了我县杂交稻制种的高产记录。能取得这样的好收成,主要是在技术上从本地条件出发,实施了“二个优选、五大改进”。
In 1987, we planted 502.6 mu of seed in the seed production site of Lijiang in Qingshan Township.

You Gui 33 system area of 71.1 acres, an average of 240.1 kilograms per mu; Shanyou Gui 33 area of 244.4 acres, 179.4 kilograms per mu; Shanyou Gui 34 area of 187.1 acres, 172.0 kilograms per mu, creating a hybrid in our county High yield records of rice seed production. To achieve such a good harvest, mainly in terms of technology from the local conditions, the implementation of the “two preferred, five major improvements.”
