摘 要：为了研究种植密度和氮用量互作对烤烟上部叶香气物质含量和感官质量的影响,以云烟87为试验材料,采用两因素裂区试验设计,通过方差分析、显著性检验和偏相关分析等方法进行了研究.结果表明：（1）种植密度和氮用量和中性致香物质含量皆呈极显著正相关关系,二者互作对上部叶中性致香物质含量增加作用明显,尤其是高密度高氮、高密度中氮、中密度高氮和中密度中氮等4个互作处理烟叶香气总量提升幅度较大；（2）种植密度和感官质量呈极显著负相关关系,而低密度、中密度分别和低氮、高氮互作则对感官评吸质量有一定的促进作用；（3）不同互作处理相比较,以中密度高氮为最好,低密度高氮、低密度中氮、高密度高氮、高密度中氮次之,高密度低氮相对较差,表明不同的种植密度和氮用量互作对上部烟叶香吃味质量影响效应明显不同.

Abstract：The effects of the interaction between planting density and nitrogen application rate on neutral aroma component contents and smoking quality of upper leaves was studied with Yunyan 87 as the sample variety usinga split-plot experiment designand the data was ananlyzed using variance analysis, significance test, partial correlation and other methods. The results showed that both planting density and nitrogen application rate had significantly positive correlation with neutral aroma component contents.The interaction of planting density and nitrogen application rate had a greater influence on the enhancement of neutral aroma component contents, especially in the following four treatmentcombinations includinghigh density high nitrogen, high density medium nitrogen, medium density high nitrogen and medium density medium nitrogen, all of which significantly improved the total aroma content of the upper leaves. Partial correlation analysis showed that planting density showed a significantly negative correlation with smoking quality. Low and medium planting density, in combination with both low nitrogen application rate and high nitrogen application rate could promote smoking quality. Compared with the comprehensive assessment of different combinations of treatments, the results indicated that the treatment combination of medium density, high nitrogen was the best and most appropriate combination in neutral aroma component contents and smoking quality, the treatmentcombinations of low density high nitrogen, low density medium nitrogen, high density high nitrogen and high density medium nitrogen were the next, and the treatment combination of high density low nitrogen was the worst compared with the other treatments. Comparison between different treatmentcombinations revealed that the influence on neutral aroma component contents and smoking quality wassignificantly different among interactions of different planting densities and nitrogen application rates.
