摘  要:
为提高烤烟下部不适用烟叶的可利用性,研究不同采摘时间及叶数其对烤烟不适用下部叶可用性的影响,分析不同采摘时间与叶片数对烟叶化学成分及评吸质量的差异。结果表明:80d采摘4片(T_5)、采摘6片(T_6)、90d采摘4片(T_8)和6片(T_9)4处理表现为香气质好,香气量足,浓度好,刺激性小,余味舒适等特点;其化学成分表现为高烟碱、两糖高、低氮和低氯特点。与采摘叶片数相比,采摘时间为影响不适用下部叶化学成分的主要因子。在烟叶大田期80~90d采摘4~6烟叶有利于提高不适用下部叶烟叶的可用性。

摘  要:
To enhance the usability of bottom leaves with low commercial value,the chemical components and smoking quality of bottom leaves with different harvesting time and leaf numbers were analyzed.Results:Picking 4leaves in 80 th d(T_5),picking 4leaves in 80 th d(T_6),picking 4leaves in 90 th d(T_8)and picking 6leaves in 90 th d(T_9)were of good quality,sufficient aroma quantity,proper concentration,little irritation and comfortable aftertaste;The chemical composition of which were of higher nicotine,higher sugar,lower nitrogen and lower chlorine.Harvesting time significantly influenced the chemical content in the usability of bottom leaves.The preliminary analysis indicated that the quality of harvesting 4~6leaves during the field period 80 th d,90 th d(harvesting leaves)was beneficial for enhancing the usability of bottom leaves with low commercial value.
