摘　　要：选取曲靖烟区典型植烟生态区(罗平县和马龙县)进行客土置换种植烤烟的试验,研究气候和土壤对多元有机酸含量和高级脂肪酸的影响。结果表明:①罗平气候条件下多元有机酸含量显著高于马龙气候,马龙气候条件下烤烟各种高级脂肪酸总含量均极显著高于罗平气候条件下烤烟的高级脂肪酸总含量;罗平土壤条件下烤烟多元有机酸总含量高于马龙土壤条件烤烟的有机酸总含量,但差异不显著,罗平土壤条件下高级脂肪酸总含量显著高于马龙土壤下烤烟的高级脂肪酸总含量。②气候对烤烟总多元有机酸和总高级脂肪酸含量的影响为高度影响效应,土壤对烤烟总多元有机酸的影响为低度影响效应,对总高级脂肪酸含量的影响为中度影响效应,气候和土壤互作对烤烟多元有机酸和高级脂肪酸含量的影响为中度影响效应。气候、土壤、气候和土壤互作对烤烟多元有机酸含量总变异的贡献率分别为54.44%、12.75%和32.81%,对高级脂肪酸含量总变异的贡献率为48.84%、33.33%和17.83%。In order to probe the effects of soil and climate on multiple organic acid and senior fatty acid contents in flue-cured tobacco,a soil-replacement experiment was carried out in two tobacco-growing areas（Luoping County and Malong County） under typical ecological conditions.The results indicated that,① the multiple organic acid content in flue-cured tobacco under the climatic conditions in Luoping was significantly higher than that under Malong climatic conditions,the senior fatty acid content in flue-cured tobacco under the climatic conditions of Malong was significantly higher than that under the climatic condition in Luoping;the multiple organic acid content in flue-cured tobacco under the soil conditions in Luoping was higher than that in Malong,but not significant,the senior fatty acid content in flue-cured tobacco on the soil in Luoping was significantly higher than that in Malong.②The effects of climate on multiple organic acid and senior fatty acid content in flue-cured tobacco were large;the effects of soil on multiple organic acid content in flue-cured to-bacco were small,the effects of soil on senior fatty acid content in flue-cured tobacco were medium;the effect of interaction of climate and soil on multiple organic acid and senior fatty acid content in flue-cured tobacco was medium;the variance contribution rates of soil,climate and their interaction to multiple organic acid content in flue-cured tobacco leaf were 54.44%,12.75% and 32.81%,and to senior fatty acid content were 48.84%,33.33% and 17.83%.
