Adopting the randomized block design and combing with analyzing the appeared quality, the inherent quality of flue-cured tobacco, the experiment studied the relationship between leaf quality and different form of leaves remained after pinch the terminal buds. In order to found can both reduce the top leaves' nicotine of flue-cured tobacco and to be able well guarantee the good technical combination and good affect on the middle and top leaves. The test result indicated that The ways of different keeping the leaf, keeping a hayfork affects remarkable impact on tobacco leaf roasted appearance quality, different the leaf numbers tobacco kept to the center, upside the leaf tobacco superior, center the superior cigarette rate's influence had not achieved the remarkable level; Different the pitchforks were kept several to the center, upside the leaf tobacco center superior cigarette rate's enhancement had extremely remarkable affects; Different the leaves and the pitchforks were kept mutual each other to oppose, upside the leaf tobacco superior cigarette rate's and center the superior smoke rate all had the extremely obvious influence. In this experiment, the leaves 20 pieces were kept pitchfork vs. and the leaves 22 pieces were kept, not to be kept the pitchfork with the leaf tobacco roasted affects outward appearance quality to be remarkable, the leaves 20 pieces were kept, a pitchfork was kept middle leaf superior smoke, center the superior smoke proportion and the even price with the leaves 22 pieces were kept, two pitchfork were kept compared which separately enhance 22ï¼…, 13ï¼…, 1.9 Yuan /Kg, the leaves 20 pieces were kept, the pitchforks were kept upside leaf tobacco the superior smoke, center the superior smoke proportion and the price separately enhanced 24ï¼…, 13ï¼…, 2.3 Yuan/Kg, to kept the leaves 22 pieces, to be not kept the pitchfork the middle leaf's superior smoke, center the superior smoke proportion and the price with keeping the leaves 22 pieces, two pitchforks were kept compared and which separately enhanced 15.2ï¼…, 11ï¼…, 1.7 Yuan/Kg, the leaves 20 pieces were kept, the pitchforks were kept upside leaf tobacco the superior smoke, center the superior smoke proportion and the even price separately enhanced 14ï¼…, 19ï¼…, 2 Yuan/Kg.Under different form of leaves remained, the middle leaves' content of k~+, petroleum ether extract, total sugar, reducing sugar and protein changed obviously. Then the influence of top leaf's main chemical components is remarkable. Processing 2,3 in experiment are better. And the influence of top leaf's aroma and taste is remarkable, processing 1,2,4 in experiment is better.The leaves 20 pieces were kept, the pitchfork was kept and which with the leaves20 pieces were kept, upside the pitchfork were kept two enhancements the leaf tobacco quality simultaneously middle the guarantee leaf's quality, the leaves 20 pieces were kept, a pitchfork upside was kept and leaf's alkaloid of tobacco content was 3.12ï¼…, the total nitrogen content was 1.96ï¼…, the ratio the leaves 20 pieces were kept and not kept the pitchfork separately reduced 0.27ï¼…, 0.24ï¼…, the total sugar content was 17.39, the ratio the leaves 20 pieces were kept and not kept the pitchfork to rise 3.39ï¼…; But the leaves 20 pieces were kept, the pitchfork kept two upside leaf's alkaloid of tobacco the content, the total nitrogen content separately reduced 3.32ï¼…, 0.76ï¼…, the total sugar rose 5.12ï¼…. After 3rd, different the leaf and the pitchfork were kept, and several pairs to roast upside the leaf tobacco fragrant to eat the taste to score points had a more tremendous influence, the leaves 20 pieces were kept and not kept the pitchfork, the leaves 20 pieces were kept, the pitchfork was kept with the leaves 22 pieces and not kept the pitchfork the fragrance to eat the taste synthesis to score points respectively was 46.49, 45.43, 43.43, remarkably was higher than other combinations, after can remarkably enhance roasts upside the leaf tobacco fragrance to eat the taste, the improvement leaf tobacco slurps the quality.According to the study, author suggested that giving stale of 2 is necessary considering of the quality promotion especially the improving of aroma and taste.
