烤烟提钾降氯技术研究进展

Research progress on potassium increase and chlorine reduction technology for flue-cured tobacco

钾、氯是烤烟的2种重要营养元素,是衡量烟叶品质的重要指标,其含量的多少对烤烟的外观品质和内在质量有重要影响。目前,我国部分烟区烟叶存在钾低氯高的问题,制约了我国优质烟叶的生产。针对这一问题,文章综述了影响烤烟烟叶钾、氯离子含量的因素,并综合介绍了近年来主要的研究技术,如灌溉技术、优化施肥方法、改进栽培措施、选育高钾低氯品种等,为烤烟烟叶的提钾降氯技术提供理论依据。

Potassium and chlorine are two important nutrients in flue-cured tobacco,which are important indicators to measure the quality of tobacco leaves,and their content has an important impact on the appearance quality and internal quality of flue-cured tobacco.At present,tobacco leaves in some tobacco areas in China have the problem of low potassium and high chlorine,which restricts the production of high-quality tobacco leaves in China.In order to solve this problem,this paper summarizes the factors affecting the potassium and chloride content of flue-cured tobacco leaves,and comprehensively introduces the main research technologies in recent years,such as irrigation technology,optimization of fertilization methods,improvement of cultivation measures,and breeding of high-potassium and low-chlorine varieties,so as to provide a theoretical basis for the potassium increase and chlorine reduction technology of flue-cured tobacco leaves.
