The invention discloses a method for improving content of potassium in tobacco leaves. The method comprises the following steps of: harvesting upper tobacco leaves with stems, knitting the upper tobacco leaves into rods, standing for 4-8 hours, digging a groove at the top end of inverted tobacco stems, injecting potassium salt solution with potassium ion concentration being 0.5-2mol / L into the groove at 1-4 times, injecting 4-6ml of the potassium salt solution at each time, standing for 2-4 hours after injection at each time, and finally hanging the tobacco leaves into a curing room for curing. The method for improving the content of the potassium in the tobacco leaves has the advantages that the content of the potassium in the tobacco leaves can be greatly improved, the commodity grade of the tobacco leaves which are treatment by adopting the method is obviously improved, the content of internal chemical components is more suitable and harmonious, the combustibility of the tobacco leaves is improved, the form of smoke is improved and the smoking quality is obviously improved.
