隆回县雨山乡野塘村有丘冈坡地16.34公顷。往年以红薯生产为主,平均667平方米红薯产量折稻谷不到200公斤。为了改变旱粮低产状况,充分挖掘丘冈坡地的增产潜力,1996年邵阳市和隆回县在该村建立杂交玉米生产示范基地,种植旱地杂交玉米13.6公顷,经市县联合测产验收,平均 Longhui County Yushan Township Yentang Village has a hill slope of 16.34 hectares. In previous years, mainly sweet potato production, an average of 667 square meters of sweet potato yield less than 200 kg of rice. In order to change the situation of low yield of dry grain and fully excavate the yield potential of Qiugang slope land, Shaoyang City and Longhui County established the demonstration base of hybrid corn in 1996 and the 13.6 hectare of hybrid corn in dry land,
