摘　　要：采用田间试验,研究施用3种常用肥料(无机复合肥、有机无机复合肥、牛栏粪与无机复合肥配施)对云南保山市烤烟有机酸含量的影响。结果表明,3种施肥处理均能提高烟草中非挥发酸、高级脂肪酸和挥发酸的含量,与施用无机复合肥相比,施用有机无机复合肥和牛栏粪与无机复合肥配施能更有效提高烤烟中主要非挥发酸(苹果酸和柠檬酸)、高级脂肪酸和除异丁酸和壬酸外的挥发酸的含量,有利于提高烟叶品质。有机无机复合肥和牛栏粪与无机复合肥配施对烤烟挥发酸含量的影响差异不显著,但施用有机无机复合肥对提高烤烟非挥发酸和高级脂肪酸含量效果更好。Field experiment was done to investigate the effects of different fertilizations（no fertilization, chemical fertilizer, organic-inorganic compound fertilizer, manure and chemical fertilizer） on organic acid in flue-cured tobacco from Baoshan, Yunnang. The results showed that 3 different fertilization treatments could increase the content of volatile acid, non-volatile acid and higher fatty acid in flue-cured tobacco. Compared with the chemical fertilizer treatment, the treatments of organic-inorganic compound fertilizer and manure and chemical fertilizer can more effectively improve the content of main non-volatile acid（malic acid and citric acid）, higher fatty acid and the most of volatile acids except isobutyric acid and nonanoic acid in flue-cured tobacco, which enhance the quality of tobacco leaves. The influence of organic-inorganic compound fertilizer and manure and chemical fertilizer on the content of volatile acid in flue-cured tobacco was not notable; but organic-inorganic compound fertilizer treatment was more effective to improve the non-volatile acids and higher fatty acids in tobacco.
