我县位于浙闽两省的边界,是一个九山半水半分田的山区。全县24.5万亩稻田,除了大约12万亩分布在海拨600公尺以下的山间盆地和沿江、沿溪的阳畈田,种植双季稻外,其余的12.5万亩中约有90%的面积每年只种一熟单季晚稻,常年亩产历来很低,多数亩产在400斤上下,拖了全县的后腿。为了改变这些单季晚稻田长期低产的落后面貌,我们于1976年开始在住龙公社龙星大队的山垅田内试种4.5亩单季杂交晚稻,获得了亩产813斤的好收成,比历史上最高亩产量翻了一番多。1977年在不同海拔高度上示范试种789亩,据21个单位315.02亩的统计,平均亩产760.2斤,比这些田1976
My county is located in the Zhejiang, Fujian and the border between the two provinces, is a mountainous area of nine mountain semi-sub-fields. In addition to about 12 million mu of mountain basins distributed over a distance of 600 meters above sea level and a total of 125,000 mu of paddy fields along the Yangtze River and Yangxi River along the stream, about 90% The area is only one-year-old single-season late rice, perennial perennial has been very low, most of the mu yield up and down in 400 pounds, dragged the county’s hind legs. In order to change the long-term low-yielding backwardness of these single-season late rice fields, we began to test 4.5-acre single-season hybrid late rice in Shandian in Longsheng Lone Star Brigade in 1976 and obtained a good yield of 813 kg per mu, The maximum mu yield more than doubled. 1977 demonstration of 789 acres of different altitudes, according to 21 units of 315.02 acres of statistics, the average yield of 760.2 kg, more than these fields 1976
