靖西县南坡公社去年在旱地(熟地)上试种39.6亩杂交水稻汕优3号,除1.5亩瘦瘠干旱的陡坡地失收外,实际有收面积38.1亩,总产干谷22,993.5斤,平均亩产603.5斤,最高亩产775.9斤,最低亩产375斤。平均亩产比本地早稻品种(250斤)增加一倍多,初步获得了成功。根据去年实践结果,旱地种杂交稻的栽培过程中要抓好以下几个技术环节: 一、土地的选择旱地种稻,根系较粗大,伸入土层较深,易发根、根毛多,所以,土地应选择阳光充足、耕作层肥沃、深厚又平坦的壤土或沙壤土的地块较好。
Jingxi County Southern slope commune last year in the dry land (Rehmannia) to test 39.6 acres of hybrid rice Shanyou 3, in addition to 1.5 acres of thin barren arid steep slope to lose, the actual area of 38.1 acres received, the total dry valley 22,993.5 kg , The average per-mu yield of 603.5 kg, the highest yield of 775.9 kg, 375 kg minimum mu yield. The average yield per mu more than doubled that of the local early rice varieties (250 kg), and initially achieved success. According to the results of last year’s practice, dryland hybrid rice cultivation process should pay attention to the following several technical aspects: First, the choice of land Dryland rice, thicker roots, extending deeper into the soil, hair roots, root hair and more, so , The land should choose sunny, fertile tillage, deep and flat loam or sandy loam plots better.
