摘　　要：钾是烟草体内重要的矿质营养元素,与烟叶品质密切相关。烟叶钾含量偏低是我国烟叶与国际优质烟叶品质差异的主要原因之一。鉴于此,从钾对烟草生长发育的作用、烟草钾吸收和转运机理、烟叶钾含量的主要影响因素及烟叶钾含量提高措施4个方面进行综述,主要概述了烟草对钾吸收和转运机理的相关研究,归纳了近年来提高烟叶钾含量的相关措施,主要包括培育高钾基因型品种、应用耐低钾基因型品种、优化施肥方式、增施有机肥、采取物理调控措施和应用化学调控措施,以期为提高烟叶钾含量和改善烟叶品质提供参考。Potassium is an important mineral nutrient element in tobacco,which is closely related to the quality of tobacco leaves.The low potassium content of tobacco leaves is one of the main reasons for the quality difference between China′s tobacco leaves and international high-quality tobacco leaves.In view of this,this paper reviewed the effect of potassium on tobacco growth and development,the mechanism of potassium absorption and transport in tobacco,the main influencing factors of potassium content in tobacco leaves,and the measures to improve potassium content in tobacco leaves.It mainly summarized the relevant research on potassium absorption and transport mechanism of tobacco,and summarized the relevant measures to improve potassium content in tobacco leaves in recent years,mainly including breeding high potassium genotype varieties,planting low potassium tolerant genotype varieties,optimizing fertilization methods,increasing organic fertilizer,taking physical control measures and applying chemical control measures,in order to provide references for improving potassium content and quality of tobacco leaves.
