烤烟氯离子来源及控制措施研究进展

Research Progress in Source and Control Measures of Chlorine Ion in Flue-cured Tobacco

氯元素是烤烟必需的营养元素,与烟草产量和品质有密切关系;氯含量过高会影响烤烟吸湿性、燃烧性等品质指标,高氯含量烤烟以我国北方烟区特别是黄淮海烟区较多。从土壤、肥料、灌溉水等方面,综述了近年来有关烤烟氯离子的来源及降低烤烟氯含量农艺措施的研究进展,提出了合理施用氯肥和有机肥、科学灌溉等技术措施的建议。

Chlorine is one of the necessary nutrition elements of flue - cured tobacco, which has close relationship with the yield and quality of tobacco. High chlorine content will affect some quality indexes of flue - cured tobacco, such as moisture absorp-tivity, combustibility and so on. Flue - cured tobacco with high chlorine content is common in northern tobacco - growing regions es-pecially in Huang - Huai - Hal tobacco - growing regions. From the aspects of soil, fertilizer, irrigation water etc, this paper sum- marized the research progress in the source of chlorine ion in flue - cured tobacco, and the agronomic measures for reducing chlorine content in flue - cured tobacco in recent years, and proposed the following suggestions ： reasonable application of chlorine fertilizer and organic fertilizer, scientific irrigation and so on.
