解放后,我省棉花良种工作取得了伟大的成绩,特别是1955年普及岱字15号后,皮棉产量和纤维品质更有很大的提高。但是我省各棉区的自然条件和耕作制度不同,栽培水平也有差别,岱字棉不能全面适应各棉区不同耕作制度和栽培水平的要求。同时岱字棉15号株型松散,结铃吐絮不够集中,在两熟栽培情况下成熟较迟。因此,选育株形紧凑、结铃率高、早熟、丰产,适合两熟栽培和机械化耕作的棉花良种是我省当前生产
After the liberation, our province has made great achievements in the field of cotton varieties. Especially after the popularity of Dai 15 on the 15th in 1955, the lint yield and the fiber quality have been greatly improved. However, the natural condition and cultivation system of different cotton districts in our province are different, and the cultivation level is also different. The Dai word cotton can not fully meet the requirements of different farming systems and cultivation levels in each cotton area. At the same time, Dai type cotton No. 15 plant type loose, boll bolting flocculus is not focused, mature in the two ripe conditions later. Therefore, the selection of plant-type compact, high boll rate, early maturity, high yield, suitable for two-crop cultivation and mechanized cultivation of cotton varieties is the current production in our province
