摘　　要：以鄂烟4号为材料,采用灌根的方法对白肋烟施用苹果酸、油酸和腐殖酸,分析了不同有机酸对白肋烟田间农艺性状、物理特性及主要化学成分的影响。结果表明:施用有机酸能够明显改善白肋烟各时期农艺性状并提高烟株田间干物质积累速率,其中以油酸处理效果最佳;不同有机酸灌根均能提高调制后叶片单叶重、填充值和叶面积,并减小叶片含梗率,同时也能有效改善叶片各主要化学成分之间的协调性,总体效果以油酸灌根处理最为显著。Taking Eyan No.4 as test material,the effects of different organic acid on the field agronomic traits,physical properties and major chemical compositions of burley tobacco were studied through applying malic acid,oleic acid and humic acid by root-pouring method.The results showed that the application of organic acid could obviously improve the agronomic traits of burley tobacco in every period,increase the dry matter accumulation rate of tobacco plants in the field,and the treatment of oleic acid had the best effect.Applying various organic acid through root-pouring could enhance the weight per leaf,filling value and leaf area after curing,decrease the stem content of leaf,and effectively improve the harmony of main chemical compositions.In conclusion,the whole effect of oleic acid application on the inherent quality was the most notable.
