以全国16个省(市)的94份烤烟样品为材料,研究了钾、氯含量及钾氯比与烟气指标的关系,结果表明:烤烟钾含量对烟气指标影响较大,随着钾含量的升高,总粒相物、烟气烟碱、烟气焦油量、烟气CO量、抽吸口教均呈降低趋势,钾含量与各烟气指标的回归关系均达极显著水平；烤烟氯含量仅与抽吸口数呈极显著曲线回归关系,而与其他指标关系不显著；烤烟钾氯比与总粒相物呈显著负相关,与烟气烟碱、烟气焦油量、烟气CO量和抽吸口数均存在显著或极显著的回归关系.%The relationships between the potassium content, chlorine content, ratio of potassium to chlorine in tobacco leaves and the smoking gas indices were studied with 94 samples of flue -cured tobacco leaves produced in 16 provinces (cities) of China. The results indicated that potassium content had significant influence on the smoking gas indices of flue - cured tobacco, and the TPM content, nicotine content, tar content, CO content and puff number of smoking gas showed decreasing trend when the potassium content increased. The regressive relationships between potassium content and all indices of smoking gas were extremely significant.. The chlorine content in flue - cured tobacco leaves just showed extremely significant curve regressive relationship with the puff number. The ratio of potassium to chlorine had significant negative correlation with TPM content, and it also had significant or very significant regressive relationships with the nicotine content, tar content, CO content and puff number of smoking gas.
