适合山地烟区的上部烟叶带茎采收留叶数研究
Study on the Numbers of Upper Leaves Harvested with Stems Suitable for Mountainous Tobacco Areas
摘要
Abstract
In order to determine the suitable number of leaves left for the upper leaves of flue-cured tobacco in mountainous areas,Yunyan 87 in Cili County,Zhangjiajie City was used as the material,and T4(retaining 4 leaves,stem-harvesting and curing),T5(retaining 5 leaves,stem-harvesting and curing),T6(retaining 6 leaves,stem-harvesting and curing)and CK(retaining 6 leaves,harvesting by priming for curing)were set up.The physiological indexes of fresh tobacco leaves and the quality of flue-cured tobacco leaves were compared and analyzed.The results showed that the SPAD value and dry matter content of fresh tobacco leaves,the proportion of variegated color,single leaf weight and yield of flue-cured tobacco leaves increased significantly with the increase of the number of remaining leaves,while the proportion of normal tobacco leaves,the rate of superior tobacco leaves,the appearance quality index,leaf thickness,leaf area quality,total sugar content,nicotine content and sugar-nicotine ratio of flue-cured tobacco leaves decreased significantly.The positive group tobacco rate of T4 and T5 treatment was the highest,which was 7.75 and 6.37 percentage points higher than CK,respectively.The superior tobacco rate of T5 treatment was the highest(77.38%),which was significantly higher than that of CK(68.74%).The output value of T6 treatment was the highest,followed by T5,which increased by 9.53%and 4.65%respectively compared with CK.The smoking quality of T5 treatment was the best,which was 5.95%higher than CK.Comprehensive analysis showed that stem picking and baking could significantly increase the yield of flue-cured tobacco,and also improve the coordination of physical characteristics and chemical components of tobacco leaves.In Zhangjiajie tobacco area,the suitable number of remaining leaves for upper leaves with stems is 5.关键词
