烤烟水肥耦合效应研究进展

Advance on Water and Fertilizer Coupling in Flue-cured Tobacco

概述了水肥耦合的概念和机理,水肥效应的关系,包括水肥对烟田土壤养分分布和有效性、烤烟生理活性、烤烟生长发育、烤烟化学成分和烤烟产质量的影响,指出了烤烟水肥耦合研究存在的问题,展望了水肥耦合技术研究方向。

The concept and mechanism of water-fertilizer coupling and the relationship between water and fertilizer in tobacco were summarized, including the effects of distribution of fertilizer and availability at different soil layers, physiological activities, different water-fertilizer combination on tobacco growth and development, contents of chemical components in tobacco leaves, yield and quality of tobacco; it focused on the present problems and causes of water-fertilizer coupling for research majors, as well as the prospects and directions of water-fertilizer coupling development were proposed.
