长绒棉的栽培管理与陆地棉相仿,工序较多,操作细致,技术性强。要获得高产优质长绒棉,一般每亩要化100个工左右。目前长绒棉原料极其缺乏,严重影响了棉纺工业的发展和出口创汇。为此开展长绒棉轻型栽培技术的研究,目的是要简化种植长绒棉的工序,以适应当前工农争劳力的矛盾,提高长绒棉的经济效益,为发展长绒棉生产创造条件。材料与方法试验品种(品系)为:上海市农科院作物所70年代从米—
The cultivation and management of long-staple cotton is similar to that of upland cotton, and there are many procedures and meticulous operations and strong technical skills. To obtain high-yield and high-quality long-staple cotton, generally about 100 workers per acre. The current lack of long-staple cotton raw materials, seriously affected the development of the cotton spinning industry and export earnings. To carry out the research on light-weight cotton cultivation techniques, the purpose is to simplify the process of planting long-staple cotton to meet the current contradictions between workers and peasants, to improve the economic benefits of long-staple cotton and create conditions for the development of long-staple cotton production.
