为研究不同施氮量对豫中浓香型烟区豫烟10号化学成分及感官质量的影响,分析了三个施氮量水平下豫烟10号上、中、下三部位烟叶的化学成分及感官质量。结果表明:中、下部烟叶以N2处理化学成分协调性较好,上部烟叶以N1处理较好;中、下部烟叶感官质量总分N2>N1>N3,上部烟叶感官质量总分N1>N2>N3。豫烟10号以中低氮处理最优。 In order to study the effects of different nitrogen rates on the chemical components and sensory qualities of Yuyan No. 10, a tobacco with high concentration in Henan Province, the chemical constituents of tobacco leaves in the upper, middle and lower parts of Yuyan No. 10 under three levels of nitrogen application were analyzed. And sensory quality. The results showed that the chemical constituents of middle and lower leaves were well coordinated with N2, while the upper leaves were better treated with N1. The total sensory qualities of middle and lower leaves were N2> N1> N3, the total sensory qualities of upper leaves were N1> N2> N3 . Yuyan 10 to low nitrogen treatment optimal.
