Abstract: This article summarized the progress of study on pedology, fertilization technology, physiology, heredity, culture and ecology about potassium nutrition of tobacco in china. The potassium in leaf is affected not only by soil available potassium, but also by the capability of uptake, transport and accumulation of potassium in tobacco. Increasing rate of potassium application can rise the content of tobacco potassium at a certain extent. There are differences between different tobacco genotypes, but the gene are not the main cause resulting in lower content of potassium. Different model of cultivation also have effect on tobacco potassium. The mechanism of potassium uptake and redistribution, the interreaction of different chemical elements in soil and plant ,the interrelation of tobacco potassium and ecological cases are all needed to investigate.
