| 摘 要： | 分析云烟品牌云南原料基地土壤及烟叶氯素特征，开展区划研究，为云烟品牌原料基地养分科学管理和烟叶工业可用性提高提供科学依据。以云烟品牌省内原料基地昆明、曲靖、红河、保山、文山5州（市）37县1130份土壤样品和中部烟叶（C3F等级）样品为材料，对其氯含量特征进行了分析和区划研究。结果表明：云烟品牌省内原料基地中部烟叶氯含量平均值为0.29%，氯含量＜0.3%的分布频率高达71.33%，0.3%-0.8%适宜区间的样品分布频率仅有22.75%。土壤氯平均含量为15.37mg/kg，样品分布频率最高的是＜10.0mg/kg区间，占61.68%，适宜区间10.0-30.0mg/kg样品分布频率仅为28.23%。水溶性氯含量最高的海拔段是1800-2000m，最低的是＜1600m；中壤土的水溶性氯含量最高，轻粘土和中粘土含量较低。云烟品牌云南原料基地中，仅有28.23%的土壤样本和22.75%的烟叶样本在适宜范围内，有61.68%的土壤样本和71.33%的烟叶样本氯含量低于适宜范围。

Chlorine Content Characteristics of Soil and Tobacco of Yunyan Brand in Yunnan Raw Material Base |
| |
| Abstract: | Taking 1130 soil samples and middle tobacco leaf samples from Yunyan brand Yunnan raw material base in 37 counties of 5 cities, we analyzed the chlorine content characteristics and carried out the zoning study. The results showed that the average chlorine content of middle tobacco leaves was 0.29%. The distribution frequency of chlorine content below 0.3% was as high as 71.33%, and the frequency of sample distribution in 0.3%-0.8% suitable range was only 22.75%. The average chlorine content of soil was 15.37 mg/kg. The highest frequency of sample distribution was <10.0 mg/kg range, accounted for 61.68%. The distribution frequency of 10.0-30.0 mg/kg samples in suitable range was only 28.23%. The highest content of water-soluble chlorine was at the altitude range of 1800-2000 m, and the lowest was <1600 m. The content of water soluble chlorine in the middle loam was the highest, and the content in light clay and medium clay was relatively low. Only 28.23% soil samples and 22.75% tobacco samples were in suitable range in Yunyan brand Yunnan raw material base. 61.68% the soil samples and 71.33% the tobacco samples had lower chlorine content than the
suitable range. |
