  摘 要:氯元素既是烤烟必需的微量元素之一,对烤烟生长发育及产质量有重要影响,也是影响烟叶质量的主要指标之一。传统观点认为烤烟是忌氯作物,生产上禁施氯肥。但是据近年来相关报道部分烟叶产区由于氯含量过低而成为影响烟叶质量的重要限制因子,以往有关烟叶氯含量的控制所做的大量研究表明,在缺氯的烟区适当施用氯肥,能够促进烟叶生长发育,并且有助于改善烟叶品质。阐述了氯离子对烤烟的生理作用,对初烤烟叶质量的影响以及烤烟氯素吸收积累规律,同时对以往增施氯肥的研究进行了综述,并对今后烤烟氯素的研究做了展望。

  Abstract:Chlorine is one of the essential trace elements of flue-cured tobacco, which has important effects on the tobacco growth, yield and quality, and the content of chlorine is one of main indicators affecting the quality of tobacco leaves. The traditional view has been that tobacco is sensitive to chlorine, so no chlorine fertilizer can be applied to the tobacco growth. In recent years, some related reports have found that chlorine has become a key limiting factor against the quality of tobacco leaves because of the low content of chlorine in some of the tobacco production areas of China. Many researches have suggested that appropriate application of chlorine fertilizer could promote tobacco growth and development, and help improve the quality of tobacco leaves in soil with low chlorine content. This paper expounds the physiological effect of chlorine ion on tobacco, influence on quality of cured tobacco leaves, and absorption and accumulation of the chlorine by tobacco, reviews the previous studies of increasing application of chlorine fertilizer, and prospects the future research of flue-cured tobacco chlorine.
