烟草钾含量提升技术研究进展

Progress in the Research on Raising-measures of Tobacco Potassium Content

钾是烟草的品质元素。与国外优质烟叶生产国家的烟叶质量比较,目前我国烟叶钾含量普遍偏低。文章从育种、施肥、物理化学调控等方面对国内外提高烟叶钾含量技术研究进展进行综述,为今后进一步提高我国烟叶钾含量提供理论依据。

Potassium was the most important quality element of tobacco,but potassium content of China tobacco leaf was lower,compared with foreign tobacco production country.This paper has reviewed on studies of tobacco leaf potassium content raising-measure in recent years in some aspects,such as breeding,fertilization,physical and chemical control which could provide the theory basis for technological measure of potassium content-raising in China tobacco leaf.
