摘　　要：分析了当前棉花生产存在的主要问题,提出了湖南棉区通过选用适当的品种,并配套以整地改垄开始,包括备种、播种、定苗、施肥、病、虫、草害防治、化学调控、化学打顶、化学催熟与脱叶等一系列田间培管技术,实现棉花集中开花、成铃吐絮,进而实现棉花机械采收的高密度直播棉花种植技术。In this paper, the current main problems of cotton production were analyzed, and the cotton cultivation technology pattern by high-density direct seeding was put forward, including a series of field training tube technology such as the selection of appropriate varieties, soil preparation and modified ridge, preparing, seeding, final singling, fertilization, diseases, insect pests and weeds harm control, chemical control, chemical topping, chemical ripening and defoliation, etc. It would centralize cotton flowering and cause to form the bell and boll opening, to realize the high-density direct seeding cultivation techniques of cotton with mechanical harvested in Hunan area.
