摘　　要：钾是烤烟生长和发育必不可少的元素之一,烟叶含钾量是评价烟叶品质的重要指标,烟叶含钾量偏低已严重制约国内烟叶生产的发展。因此,提高烟叶含钾量对改善烟叶内在品质具有重要的现实意义。笔者综述了钾元素的生理功能、钾元素对烟叶品质影响、生物钾肥对烤烟生长发育、烟叶含钾量、烟叶品质的影响以及生物钾肥有效施用条件等方面的研究进展,归纳了生物钾肥对烤烟生长发育、产量、品质具有重要决定作用,在此基础探讨了提高烟叶含钾量的有效途径及措施,认为施用生物钾肥是进一步提高中国烟叶内在品质的有效途径之一,最后对生物钾肥今后研究方向进行了展望。Potassium is one of the elements essential for the growth and development of flue-cured tobacco,potassium content is an important indicator of quality of flue-cured tobacco, low potassium content of flue-cured tobacco severely restricts the development of tobacco production. Therefore, it is of great practicalsignificance to improve the potassium content of flue- cured tobacco to enhance the quality of flue- curedtobacco in China. The authors reviewed the effect of potassium on physiological function and quality of flue-cured tobacco, effect of biological potassium fertilizer on development, potassium content, quality of flue-curedtobacco and conditions for effective application of biological potassium fertilizer. The effects of biologicalpotassium fertilizer on the growth, yield and quality of flue-cured tobacco were summarized. On the basis ofthe above discussion, the techniques for increasing the potassium content of flue-cured tobacco were proposed.It was believed that biological potassium fertilizer was one of the effective ways to improve the quality of flue-cured tobacco in China. The authors made an outlook on the future research of biological potassium fertilizer.
