钾素对烤烟产质量影响及提钾措施的研究进展

Effect of Potassium on the Yield and Quality of Tobacco and Progress of Study on Improving Mea sures

钾是植物生长的大量元素,也是烤烟生长的必需矿质元素,烟叶中钾含量是评价烟叶内在品质的重要指标之一,钾含量偏低或不足,严重影响着烟叶燃烧性和持火力,不利于烟叶产量和品质的提高,同时钾又是参与许多生理生化反应过程的重要元素,因此合理提高烟叶钾含量,对改善烟叶品质、提高烟叶产量、提升烟叶工业可用性具有重要意义。探讨了钾元素对烤烟的综合影响及如何运用外源物质、栽培措施及现代技术等方法提高烟叶钾含量。

Potassium is essential macro elements to plant and the flue-cured tobacco growth,potassium is also one of important indexes to evaluate inner quality of flue-cured tobacco.the Lower or the insufficient potassium content will have a severe impact on tobacco combustibility and hold fire,and may not favorable to the yield and quality.meanwhile potassium is importance chemical element,involving in many physiological and biochemi cal reaction process.It is important that the industrial utilization can be improved and also increases the yield and quality of tobacco leaves by raising the potassium content in tobacco.In this paper we mainly discusses the integrated effect of the potassium on tobacco and how to use foreign substances and cultivation measures and methods of modern technology to improve tobacco potassium content.
