我县目前水利尚未过关的山旱田面积约17800亩,占全县水田总面积的7.4%。这一类田过去大都种植常规中稻品种,产量低而不稳。为了提高这类稻田的产量,1983年我站受地、县科委和农业局的委托,在山旱田进行了一季杂交早稻栽培试验。试验地海拔370米,温光资源较丰富,但缺乏良好的灌

At present, the water area in our county has yet to pass the mountain dry farmland area of ​​about 17,800 mu, accounting for 7.4% of the total paddy field area of ​​the county.

In order to improve the yield of such paddy fields, in 1983 I was stationed by the prefectural committee of science and agriculture and commissioned the commissioning of the first season hybrid rice cultivation experiment in the mountain dry field. Test 370 meters above sea level, temperature and light more abundant resources, but the lack of good irrigation
