长江流域发展机采棉的现状与展望

分析了目前国际国内形势复杂变化的情况下，发展长江流域机采棉产业的现状和必要性，明确了长江流域发展机采棉的优势，分析了机采棉推广面临的问题与挑战，探讨了长江流域机采棉发展的战略。对以下几个方面提出合理化建议：长江流域机采棉发展区域化优化布局；充分利用本区域冬闲田发展小麦、油菜作物；在长江流域两湖（洞庭湖、鄱阳湖）两江（长江、汉江）近700000 hm2滩涂旱地宜棉区扩大种植棉油（麦）双直播双机采；形成以棉增油、棉油双稳的格局。

Present Situation and Prospect of Developing Machine Picked Cotton in the Yangtze River Basin

Based on the analysis of the complex changes of the international and domestic cotton situation, this paper describes the current situation and necessity of developing the machine picked cotton industry in the Yangtze River Basin. The advantages of developing machine picked cotton are clarified. We expound the problems and challenges faced by the popularization of machine picked cotton, and discuss the development strategy of machine picked cotton. We provide rational suggestions for the following aspects. The regional and optimized layout for mechanized cotton harvesting shall be developed in the Yangtze River basin. Make full use of the winter fallow fields in the region to develop wheat and rape crops. In the two lakes (Dongting Lake and Poyang Lake) and the two rivers (Yangtze River and Hanjiang River) areas of the Yangtze River Basin, cotton and rape (wheat) double direct seeding and double machine harvesting shall be expanded in nearly 700 thousand hectares of tidal flat and dry land suitable for cotton production. Form a pattern of increasing cotton area and stabilizing rape area in the Yangtze River Basin.
