生物钾肥对烤烟含钾量及品质影响的研究进展

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。

Advance in Effect of Biotic Potassium Application on Potassium Content and Quality of Flue-cured Tobacco

Potassium was one of the elements essential for the growth and development of Flue-cured Tobacco, potassium content was an important indicator of quality of Flue-cured Tobacco, low potassium content of Flue-cured Tobacco had severely restricted the development of tobacco production. Therefore, it was of great practical significance to improve the potassium content of Flue-cured Tobacco to improve the quality of Flue-cured Tobacco 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-cured Tobacco and conditions for effective application of biological potassium fertilizer. The effects of biological potassium fertilizer on the growth, yield and quality of Flue-cured Tobacco were summarized, On the basis of the 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.
