棉花油后直播在湖南棉田生产机械化中的作用

Effect of Direct Seeding of Cotton after Rape Harvest in Mechanization of Cotton Production in Hunan Province

分析当前棉花生产机械化的概况和长江流域棉花机采的可能性,认为棉花油后直播有利机械收花、减少劳动工序、降低成本、缩短生育期、减轻病虫害、提高产量和节地增收。提出了发展棉花油后直播的关键技术是:选择适宜的品种、精准播种、水肥管理与化调、集中收花和搞好前后作物的衔接。并指出棉花油后直播将成为实现长江流域棉区棉田生产机械化的一项重要技术突破。

At first, the general situations of cotton production mechanization at present and the possibility of mechanical harvest of cotton in Yangtze River Basin were analyzed. Then, the technical ideas for development of direct seeding of cotton after rape harvest were proposed, and the feasibility and method of direct seeding of cotton after Rape harvest were introduced. In the end, it pointed out that the direct seeding of cotton after rape harvest will become an important technical breakthrough for realizing cotton production mechanization in Yangtze River Basin.
