摘  要：
为了确定适宜四川万源晒黄烟的氮用量和氮钾比例,比较了不同氮用量和氮钾比例对不同品种晒黄烟化学成分含量和感官评吸质量的影响.结果表明:晒黄烟品种晒92414和青梗为晒黄烟调味香型,风格程度均较显著,劲头适中;2个品种的烟叶化学成分含量差异明显,品种青梗的糖含量较高,烟碱和总氮含量较低.氮用量和氮钾比例对不同品种的不同化学成分含量影响程度有差异,纯氮用量、氮钾比例对晒黄烟评吸烟气浓度影响均达到显著水平,氮钾比例对评吸总分的影响大于纯氮用量;氮钾比例对晒92414评吸质量的影响较大,纯氮用量对品种青梗评吸质量的影响较大.综合来看,品种晒92414和青梗适宜施纯氮15 kg/667m~2,适宜晒92414的NPK比例为1∶0.5∶3,适宜青梗的NPK比例为1∶0.5∶1.

摘  要：
In order to determine the appropriate nitrogen and nitrogen-potassium ratio for different varieties of sun-cured yellow tobacco in Wanyuan, the effects of two factors on the chemical composition content and sensory smoking quality of different varieties of sun-cured yellow tobacco were compared. The results showed that Shai 92414 and Qinggeng were the flavor types, the style degree was significant and the strength was moderate; the chemical components of tobacco leaves of the two varieties were significantly different, the sugar content of Qinggeng was higher, the nicotine and total nitrogen content were lower. The effects of nitrogen and nitrogen-potassium ratio on the content of different chemical components of different varieties were different. The effects of pure nitrogen and nitrogen-potassium ratio on the smoke concentration of sun-cured yellow tobacco were significant. The effects of nitrogen-potassium ratio on the total score of smoking quality were greater than that of pure nitrogen; the ratio of nitrogen and potassium had a greater impact on the smoking quality of the Shai 92414, and the amount of pure nitrogen had a greater impact on the smoking quality of the Qinggeng. In general, the variety Shai 92414 and Qinggeng are suitable for applying pure nitrogen 225 kg/hm~2, the NPK Ratio of Shai 92414 is 1 ∶ 0.5 ∶ 3, and the NPK Ratio of Qinggeng is 1 ∶ 0.5 ∶ 1.
