我省发展杂交水稻已有九年的历史。九年来可以概括为三句话:“三年研究出成果;三年试种很成功;三年推广大增产。”充分显示了杂交水稻在粮食生产上的作用。首先是有力地改变了高山区的水稻低产面貌。在我省高海拔山区,秋寒早,春暖迟,早稻不保险,晚稻更危险,长期背着低产包袱,怎么也丢不掉。常有人说,山区地无一里平,土质差,气候冷,水温低,想要水稻高产难。推广杂交水稻以来,一般每亩增产200～300斤,有的成倍增产,一季超《纲要》、亩产过千斤到处涌现。一九七七年浦城县九牧公社阳屯大队在海拔700米高的山田种了1800亩单季杂交稻,平均亩产
The development of hybrid rice in our province has been nine years of history. Three years can be summed up in three sentences: “Three years of research results; three years of successful trials; three years to promote large-scale production.” Fully demonstrated the role of hybrid rice in food production. The first is to forcefully change the low-yielding rice landscape in high mountain areas. High altitude in the mountains in our province, early autumn cold, late spring, early rice is not insurance, late rice is more dangerous, long-term carrying low-yield burden, how can not afford to lose. It is often said that there is no one in the mountain area, poor soil quality, cold climate, low water temperature and high yield of rice. Since the popularization of hybrid rice, the general increase of 200 to 300 kg per mu, and some doubled production, super-one season, “outline”, per kilogram emerging over thousands of pounds. In 1977, the Yangtun Brigade of Jiumu Commune in Pucheng County planted 1,800 mu of single-season hybrid rice in the Yamada, 700 m above sea level, with an average yield per mu
