我国烟草钾素研究的现状与展望

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。

Current status and prospects of researches on tobacco potassium nutrition in China

This paper summarized the physiological functions of potassium on plants and the importance of the element on tobacco quality.Since the increasing application of potassium and the improvement of comprehensively agronomic measures,the potassium content in tobacco leaves has been increased to a higher level than before.The general level in China,however,is currently lower than that of quality tobacco in USA and other major tobacco producers.It was pointed out that the further studies in physioecology,nutritional genetics and molecular biology of tobacco should be strengthened so as to resolve the problems in lower content of potassium in tobacco produced in China.
