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.
