我县处于北纬27°,云贵高原东北部,海拔1000公尺左右,无霜期240天,年均温15℃,年雨量1040mm。1977年开始试种杂稻和品种比较试验中,“南优二号”小区产量达到1502斤,超过常规稻一季栽培的历史最高水平,显示了杂交稻的优越性和云贵高原栽培杂稻的巨大增产潜力。为了充分利用云贵高原的自然特点,进一步挖掘杂稻在云贵高原山区作一季栽培的生产潜力,1978年在平洛公社双寨大队农科队设置6.7亩高产
My county is at latitude 27 ° north-east Yunnan-Guizhou Plateau, an elevation of 1000 meters, 240 days frost-free period, the average annual temperature of 15 ℃, the annual rainfall of 1040mm. In 1977, the trial of hybrid rice and varieties of comparative trials, “South You 2” district output reached 1502 pounds, exceeding the highest level of conventional rice cultivation in the first quarter, showing the superiority of hybrid rice and Yunnan-Guizhou Plateau cultivation of hybrid rice huge Yield potential. In order to make full use of the natural features of the Yunnan-Guizhou Plateau to further tap the potential of hybrid rice in the mountainous areas of Yunnan-Guizhou Plateau for cultivation in one season, in 1978 in Pingluo Shuangzhai Brigade agricultural team set 6.7 acres of high yield
