Abstract: Developing the slow/controlled release fertilizers (SRFs) of flue-cured tobacco has great significance in protecting ecological environment and reducing agricultural production costs. In this paper, the internal and external research and application literatures of SRFs were summarized. The SRFs’ concept and characteristics were introduced firstly, and then the effects of SRFs on the growth, K content, quality and economic traits of flue cured tobacco were reviewed, and some problems in current research were pointed out. The SRFs was beneficial to the growth of tobacco, increase of K content in soil and leaves, improvement of quality and enhancing the yield and output value of flue-cured tobacco. But it also had insufficient research in the coated material of SRFs and mechanism, and had poor study about the SRFs mixed with the ordinary fertilizer applications. Therefore，it is necessary to discuss the development of present situation, prospects, problems and countermeasures about the SRFs at home and abroad, so as to provide theoretical basis for industrialization of the SRFs in our country.

Key words: slow/controlled release K fertilizers, flue-cured tobacco

摘要： 发展烤烟缓/控释钾肥对于保护生态环境及降低农业生产成本具有重要的意义。总结了国内外有关缓/控释钾肥在烤烟上的相关研究和应用进展，介绍了缓/控释钾肥的基本概念，就缓/控释钾肥对烤烟生长发育、烟叶钾含量及品质性状、经济性状、土壤钾含量的影响作了综述，并且提出了当前研究中的一些问题。缓/控释钾肥能够促进烤烟的生长，提高土壤钾含量，进而提高烟叶钾含量，改善烟叶品质，增加产量产值，但也存在控释钾肥包膜材料和机理研究不足、与普通肥配施研究较少等问题，因此有必要就缓/控释钾肥在国内外的发展现状、前景、存在问题及对策予以讨论，以期为我国缓/控释钾肥产业化提供理论依据。
