研究了陆良县海拔1800～2300 m 区域的水稻土、红壤2种土壤类型共计320个土样的养分状况及中部烟叶的化学成分。结果表明，陆良县各海拔植烟土壤均存在一定程度的缺钾状况，烤后烟叶的总糖含量偏高。水稻土条件下，烟叶钾离子含量与土壤有机质的含量呈显著负相关，烤烟糖碱比与土壤 pH 显著负相关，与有效磷、速效钾的含量呈极显著正相关；红壤条件下，烟叶总糖和还原糖的含量与海拔高度呈显著正相关，与土壤 pH 呈极显著负相关，烟叶钾离子含量与海拔高度、土壤速效钾的含量呈极显著正相关。陆良烟区海拔组2（1900～2000 m）的红壤及海拔组3（2000～2100 m）的水稻土烤烟化学成分更协调，更适合发展优质烤烟。

The relationships of chemical composition in tobacco leaf at the different altitudes and soil types of Luliang were studied in this paper.The results showed that,different soil types in all altitudes of Luliang tobacco -growing areas were short of available potassium,total sugar of flue -cured tobacco leaf was overweight.For paddy soil,there were negative cor-relations between available potassium of tobacco leaf and organic matter of soil,sugar -nicotine ratio of tobacco leaf and soil pH,available potassium,available phosphorous of soil.In the condition of red soil,there were significantly positive cor-relations between total sugar of tobacco leaf and altitude,reducing sugar of tobacco leaf and altitude.There were significant negative correlations between total sugar of tobacco leaf and soil pH.Significantly positive correlation was showed between potassium of tobacco leaf and altitude,soil available potassium.In conclusion,red soil of Luliang tobacco -growing areas under 1 900 ~2 000 m altitude and 2 000 ~2 100 m elevation in red soil and paddy soil was more suitable for the develop-ment of high quality flue -cured tobacco.
