Abstract: This article mainly summarized the regulation technology of potassium in tobacco plant and the characteristics of absorbtion, accumulation and distribution of potassium by tobacco plant.The cases of soil and climate all have effect on tobacco potassium.The uptake rate of potassium before mature is high and begin to lower after that. The accumulation of potassium in leaf is lower then other organ.It is necessary for taking measures to regulate the distribution among different organs to improve the potassium of leaf.But now all these regulative measures could not remarkably improve the content of potassium in leaf.It needs to study the intrinsic mechanism responsible for potassium accumulation of tobacco.
