芝麻饼肥与化肥不同比例配施对不同叶位烤烟烟叶化学成分和香气成分含量、组成的影响及其作用机理的探讨，表明以50%芝麻饼肥+50%化肥处理使上、中、下部烟叶糖碱比都较适宜，化学成分协调，新植二烯、酮类、醛类等香气物质总含量明显提高，明显改善了烟叶的综合品质，表现为烟叶香气质纯净、香气量大、柔和、杂气小、烟气净、余味舒适、劲头适中、燃烧性好，总得分提高，显著减小了叶位之间的质量差异，因此，推荐河南省植烟区烤烟生产以50%芝麻饼肥+50%化肥配施为宜。
It is still unclear how seed cake fertilizer affects the aroma compounds of flue-cured tobacco leaves. The results for the optimum application rate of sesame seed cake fertilizer and chemical fertilizer for a good quality of flue-cured tobacco leaves were inconsistent in previous reports , and most of them were gained based on the research using middle leaves of tobacco. In this study, the responses of chemical properties and aroma compounds of flue-cured tobacco leaves in different positions of plant to the proportional application of see cake fertilizer and chemical fertilizer were tested and the underlying mechanism of flue-cured tobacco flavor quality was explored using upper, middle and lower tobacco leaves. The results showed that application of 50% sesame cake and 50% chemical fertilizer could result in a suitable ratio of nicotine to sugar and higher neophytadiene, ketons and aldehyde contents for all leaves in different positions of tobacco plant grown in the mid-fertilize brown soil of Henan Province, therefore, the comprehensive quality of tobacco was improved , having small odor, suitable irritation, comfortable lingering smell, mild smoke and good combustibility. The quality discrepancy between the leaves in different positions was also diminished. Based on results obtained in our research, we recommend the optimal fertilizer blends for the tobacco grown in Henan Province as 50% sesame cake nitrogen with 50% chemical fertilizer nitrogen.
