贵阳烟区云烟87不同长相中棵烟产量和质量比较分析

为进一步提升烤后烟叶品质，为贵阳烟区提供理想中棵烟株型判别标准，以云烟87为试验材料，研究成熟期3种不同长相的中棵烟（T1：小，T2：中，T3：大）烤后烟叶产量和质量。结果显示，不同长相中棵烟烤后烟叶经济性状及烟叶品质差异显著，T2处理烟株的产量和质量最为协调，单位面积产值最高，达55188.15元/hm2，烤后上等烟比例达60.23%，较T1和T3处理分别提高了12.24%和8.59%;T2处理烟叶均价最高，为27.12元/kg，较T1和T3处理分别高出2.14和1.47元/kg;T2处理烟叶油分较多，色度较强，化学协调性优于其他2种株型中棵烟，感官质量总得分比T1和T3处理分别提高2.30和1.63分。综上所述，贵阳烟区理想中棵烟株型形态参数以株高109.30cm、茎围10.70cm、节距5.70cm、留叶数17.33、腰叶长73.97cm和腰叶宽32.43cm为宜。

Comparative Analysis of Yield and Quality of Yunyan 87 with Different Moderate Plant Shapes in Guiyang Tobacco Area

In order to improve the flue-cured tobacco quality and provide the discriminant standard of ideal moderate plant shapes in Guiyang tobacco area, Yunyan 87 was used as material to study the yield and quality of tobacco with different moderate plant shapes (T1: small, T2: medium, T3: large). The results showed that, there were significant differences in economic characters and quality of flue-cured tobacco among different plant shapes: the yield and quality of T2 treatment was the most coordinated, the output value was the highest, reaching 55 188.15 yuan/ha, and the proportion of high-grade tobacco reached 60.23%, which was 12.34, 8.59 percentage points higher than that of the T1 and T3 treatments, respectively. The average price of T2 treatment was the highest (27.12 yuan/kg), 2.14 and 1.47 yuan/kg higher than that of the T1 and T3 treatments, respectively. T2 treatment had more oil content and strong chromaticity, and its chemical coordination was better than that of the other two plant shapes. The total score of sensory quality of the T2 treatment tobacco was 2.30, 1.63 points higher than that of the T1 and T3 treatments, and the honey sweet fragrance style was more prominent. To sum up, the morphological parameters of ideal moderate plant shapes in Guiyang tobacco area were plant height 109.30cm, stem girth 10.70cm, pitch 5.70cm, remaining leaf number 17.33, cutters length 73.97cm and cutters leaf width 32.43cm.
