This paper studies the different harvesting methods on quality of upper leaves of flue cured tobacco effects. Its purpose is to further improve the intrinsic quality of upper leaves of Flue-cured tobacco. In Luoyang Songxian on three different harvesting methods of test sample inspection, found that disposable income of upper leaves of flue-cured tobacco harvest as medium to slightly thick, oil to have multiple, structure loose-is loose, various chemical composition content is moderate, and between the proportion of co-ordination, good aroma quality, aroma quantity is sufficient, eat mellow taste and aftertaste, pure, less irritating, miscellaneous gas lighter, classy smoke scale, improve industrial enterprises, fully meet the quality requirements, greatly improving the utilization rate of upper leaves of flue cured tobacco. And from the physical properties of detection result:leaf thickness, leaf density, tensile, stem content and other major indicators of seven relatively outstanding performance. Especially the one-time harvest income upper smoke aroma substance content increased significantly, coordination chemical components, quality good. Disposable stalk harvesting methods although also can obviously improve the intrinsic quality of upper leaves of flue-cured tobacco, improve quality of tobacco, but and disposable recovery methods, it has the obvious defects, which greatly increased labor costs, reducing the farmers income.
