为了弄清钾肥对烤烟致香物质含量的影响，采用田间试验，以云烟87为材料，探讨了钾肥基、追施比例和施用量对豫西烤烟叶片中性致香物质含量的影响。结果表明，钾肥施用量和施用比例对烤烟中上部叶中性致香物质总量和各降解产物含量的影响各不相同。增施钾肥可明显提高上部叶各类中性致香物质总量，其中中钾水平上高施追肥和高钾水平上低施追肥质体色素类致香物质含量最高，高钾水平高施追肥非质体色素类降解产物含量最高。低钾水平上高施追肥则更有利于中部叶各类香气物质的形成。

In order to identify the effects of potassium (K) fertilization regulation on aroma constituents in flue-cured tobacco leave, a field experiment was conducted to study the changes of K rates and proportion of base K to dress K fertilizer on the neutral aroma constituents in middle and upper leaves of tobacco (cv. Yunyan 87). The results showed that the contents of the all neutral aroma constituents and every degradation products were different under the different potassium fertilization rates and ratios. Neutral aroma constituents in upper leaves increased with the higher potassium rate. The content of plastid pigment degradation products in upper leaves were the highest relatively under top dressing fertilizer of middle potassium level and low dressing fertilizer of high potassium level, while the non-plastid pigment degradation products was the highest under top dressing fertilizer of high potassium level. It was more conducive to the formation of neutral aroma constituents in middle leaves under top dressing fertilizer of low potassium level.
