概述了钾的生理功能及其对烟草品质的重要性。由于增施钾肥和改进综合农艺措施，我国烟叶含钾量有了一定提高，但尚未达到优质水平。要最终解决烟叶低钾问题仍需进一步加强烟草生理生态、营养遗传、分子生物学方面的研究
The physiological functions of potassium and their importance to tobacco quality are outlined. Due to the increase of potash fertilizer and the improvement of comprehensive agronomic practices, the potassium content of tobacco in our country has been increased to some extent, but it has not yet reached the high quality level. It is still necessary to further strengthen the research on tobacco eco-physiology, nutrition and genetics and molecular biology in order to finally solve the problem of low potassium in tobacco leaves
