关于优化棉田农作制度的思考

根据长江中下游棉区优越的自然资源气候特点和丰富的农作物品种资源,建议优化棉田农作制度,改进耕作栽培技术,并从合理复种布局、选择适宜作物品种、育苗移栽、科学施肥与化控、控制间套作物密度、优化病虫防治方式等方面提出了发展对策。因地制宜的发展棉田棉、粮、菜间作套种复种技术,能提高土地利用率和资源产出率,达到间套作物平衡增产,从而提高棉田整体经济效益,实现棉农增收的目的。

Thinking about the Optimization of Cotton Farming System

According to the climate characteristics of natural resources and abundant crop varieties resources in the Yangtze River Region, this paper presents that can improved cultivation techniques by optimize the cotton farming system, some development countermeasures are put forward from the aspects of reasonable multiple cropping arrangement, selection of suitable crop varieties, seedling transplanting, scientific fertilization and chemical control, the control of plant density, and the optimization of pest control methods. Meanwhile, in order to improve land use efficiency and resource output rate, some intercropping technology should be development including cotton intercropping grain crops, Cotton intercropping vegetables. Therefore, the overall economic benefits of cotton and income of farmers were improved by taken intercropping technology of cotton field.
