桂北(我区桂林以北的全州、兴安、灌阳,資源等县)这个地区历来的种植习慣,是以单季稻为主,采用水稻荞麦、水稻大豆、水稻油菜、水稻蘿卜和水稻紅薯等复种方式,并結合冬种绿肥,一年两熟或多熟;解放前从未种过双季稻。解放后为了进一步增产粮食,自1955年开始試驗推广了双季稻。至1960年止,双季稻占水田的面积,有的生产大队是5—10%,有的占10—20%,还有的达到30%左右。但是,改种的双季稻 The traditional habit of planting in the northern part of Gui North (the districts of Quanzhou, Xing’an, Guanyang, and resources in the north of Guilin in our district) is based on single season rice, using rice buckwheat, rice soybean, rice rape, rice radish and rice sweet potato Such as double cropping methods, combined with winter-type green manure, two or more cooked a year; never planted double crop before liberation.
