利用2007~2011年南阳烟叶质量监测数据研究了南阳烟叶质量现状。结果表明:南阳烟叶外观质量较好,各部位烟叶综合得分居全省前列;其感官质量处于中等偏上水平,香气质好,香气量足,劲头适中,具有较强的配伍性;南阳烟叶化学成分比较协调,烟碱、总氮含量一般在1.5%~3.5%的适宜区间,两糖差均小于3,两糖比为0.89~0.98,氯离子含量大都在0.8%以下,符合优质烟叶指标。在分析了烟叶各种成分的含量、年际间的变异特点和变化趋势后,针对南阳烟叶质量方面的不足,提出了相应的对策。
Using the quality monitoring data of Nanyang tobacco from 2007 to 2011, the quality status of Nanyang tobacco leaf was studied. The results showed that the appearance quality of Nanyang tobacco was better, and the comprehensive score of tobacco in each part was the forerunner in the whole province. The sensory quality was moderately upper, with good aroma quality, adequate aroma, moderate momentum and strong compatibility. The contents of nicotine and total nitrogen are generally in the suitable range of 1.5% ~ 3.5%, the difference between two sugar is less than 3, the ratio of two sugar is 0.89 ~ 0.98, the content of chloride is mostly below 0.8%, which accords with the index of high quality tobacco. After analyzing the contents of various components of tobacco leaves, the variation characteristics and the trend of variation during the inter-annual period, the countermeasures were put forward in view of the deficiencies of quality of Nanyang tobacco leaves.
