摘　　要：我国水分和肥料等利用效率较低,不合理的施肥加重了肥料流失、病虫害发生、土壤和水体污染等。为了对烟草生长发育过程中达到最佳的水肥耦合模式提供参考,概述了水肥耦合的概念和机理,总结了我国烟草水肥耦合研究的现状和存在的问题;提出了从实施水肥一体化,建立高效水肥管理信息系统等方面开展水肥互作的研究建议。The paper reviews the conception and mechanism of water-fertilizer coupling and proposes the suggestions to study water-fertilizer interaction from the angles of implementing water-fertilizer integration and building the efficient information system of water-fertilizer management by summing up the current situation and problems of water-fertilizer coupling research in tobacco to provide a reference for achieving the optimum water-fertilizer coupling model during tobacco growth and development and solve the problems of fertilizer loss, pests, pollution of soil and water by unreasonably application and lower utilization rate of water and fertilizer in China.
