摘　　要：烟叶钾含量对改善烟草品质至关重要,与国际优质烟叶相比,我国烟叶钾含量低,面对这一现状,我国烟草科技工作者,从多维度进行烟叶钾含量的研究,旨在提高我国烟叶钾含量.本文主要从土壤理化因子、气候因子和地理因子等生态因子角度,总结我国近十年来的大量研究结果.在土壤理化因子方面,对烟叶钾含量影响研究较明确的因子有土壤p H、有机质及土壤有效钾含量,其余土壤理化因子对烟叶钾含量的影响还存在诸多分歧;在气候因子和地理因子方面,虽然我国烟草科技工作者从不同方面进行了研究分析,但研究结果更多存在分歧和争议,本文在肯定具有明确研究结果的基础上,对存在分歧影响因子进行了梳理,为进一步的研究提供参考.Potassium content in tobacco leaves is very important for the improvement of tobacco quality. Compared with international high-quality tobacco,the potassium content is low in Chinese tobacco leaves. In this situation,Chinese tobacco researchers have carried out multi-dimensional research on potassium content in tobacco leaves in order to improve the potassium content in Chinese tobacco leaves. This paper summarizes the results of a large number of researches in China in the past ten years from the perspectives of the soil physical and chemical factors,climatic factors and topographic factors. The soil physical and chemical factors that have clear effects on the potassium content of tobacco leaves are soil pH,organic matter,and soil available potassium content. There are still many differences in the effects of other soil physical and chemical factors on the potassium content of tobacco leaves. As to climatic factors and geographical factors,although the tobacco researchers in China have conducted research and analysis from different aspects,the research results are more divergent and controversial. Based on the clear research results,this paper sorts out the influencing factors that have differences and provides references for further research.
