我县地处川东南盆边山地,平均海拔500米以上,水稻田分布在500—1,300米地区,其中杂交水稻分布于500—800米处。由于山区生态条件特殊(前有低温,中有伏旱,后有秋风),自1978年以来,我们从外地引进了温室育秧技术,特别是因地制宜利用冬水田摘小苗直栽,大面积获得成功,并逐年扩大,1983年杂交稻小苗 My county is located in southeastern Sichuan basin mountain, with an average elevation of 500 meters above sea level, paddy fields located in the 500-1,300 meters area, of which hybrid rice distribution at 500-800 meters. Since the special ecological conditions in the mountain area (before the low temperature, in a drought, autumn after the wind), since 1978, we introduced greenhouse seedling technology from the field, especially in light of local conditions, the use of winter paddy field picking seedlings planted straight, large areas of success and Expand year by year, 1983 hybrid rice seedlings
