摘　　要：采用调查研究和田间试验对保山市烟叶氯含量状况进行了分析研究;根据调查分析结果,进行了不同施氯量的田间试验。结果表明：保山烟叶含氯量很低,平均为0.12%,变幅为0.01%P-0.97%,有91.08%的烟叶样本含氯量低于优质烟叶要求的含氯下限（0.3%）,缺氯的烤烟样品占8.91%。烟叶含氯量低已成为影响保山烟叶质量的因素之一;在该地区氯含量较低的土壤上,施用氯肥不仅可以提高烟叶的产量、产值、上中等烟比例、均价,而且还可改善烟叶的外观质量和内在品质,主要表现为使烟叶颜色加深、色度增强、油分增加,烟叶中氯、钾、糖含量也随施氯量的增加而增加。The content of chlorine in flue-cured tobacco leaves,as well as the effect of different amount of chlorine applying to fields,was studied by investigation and field experiments in Baoshan.The results of investigation indicated the content of chlorine in tobacco leaves was very low,and the average content was 0.12% with the range of 0.01% to 0.97% in Baoshan.Tobacco leaves samples deficient in chlorine（0.025 %） accounted for 8.91% of the total.The chlorine contents in 91.08% of the leaves samples were lower than 0.3% which was the lower limit of high quality tobacco leaves.The yield,the rate of middle to the first class leaf,the average price,the production value,the appearance quality and the contents of chlorine,total sugar,potassium of flue-cured tobacco leaves were improved while the amount of Cl-was increased from 0 to 26.25 kg/hm^2 in the soil with low water-soluble Cl^-.
