摘要:

为探究自然界中UV辐射曝辐量对烤烟烟叶主要化学成分的影响,利用十堰地区8个烟叶气象站自然状态下近10 a的UV辐射资料,结合各个植烟区烟叶主要化学成分数据,对其间的相关程度进行了分析。结果表明:(1)房县和竹溪县植烟区大田期和各生育阶段UV辐射曝辐量呈增加趋势,竹山县和郧西县植烟区大田期UV辐射曝辐量随年际变化呈下降趋势,其中竹山县植烟区大田期和各生育阶段下降较为明显,主要体现在旺长阶段和成熟阶段;(2)同时期不同植烟区烟叶主要化学成分含量及其比值不稳定,变异系数差别较大,存在较大的空间差异;(3)UV辐射曝辐量与烟叶部分主要化学成分密切相关,其中UV辐射曝辐量与烟碱含量呈正相关,与总氮含量、钾含量呈负相关,总糖、还原糖和氯含量受UV辐射曝辐量影响作用较小。研究通过对UV辐射曝辐量对烟叶化学成分影响分析,探讨UV辐射曝辐量与烟叶主要化学成分之间关系,为烟叶品质鉴定提供了科学依据,并为优质特色烟叶区域定位和产区布局提供参考。

Abstract:

In order to explore the effect of UV radiation exposure on the main chemical components of flue-cured tobacco, the UV radiation data of 8 tobacco automatic stations in Shiyan area in recent 10 years were used to analyze the correlation degree of the main chemical components of tobacco leaves in different parts of each tobacco planting area. The results showed that: (1) the UV radiation exposure in the field stage and each growth stage in the tobacco planting areas of Fangxian and Zhuxi Counties showed an increasing trend; in the tobacco-growing areas of Zhushan County and Yunxi County, the UV radiation exposure in the field stage showed a decreasing trend with the interannual variation, and the decrease was more obvious in the field stage and various growth stages in the tobacco-growing areas of Zhushan County, mainly in the flourishing and mature stages. (2) The contents and ratios of the main chemical components of tobacco leaves in different tobacco planting areas were unstable, the coefficient of variation was different, and there was a large spatial difference. (3) UV radiation exposure was closely related to some major chemical components of tobacco leaves. Among which, UV radiation exposure was positively correlated with nicotine content, and negatively correlated with total nitrogen content and potassium content; the contents of total sugar, reducing sugar and chlorine were less affected by UV radiation exposure. In this paper, the relationship between UV radiation exposure and the main chemical components of tobacco was discussed through the analysis of the influence of UV radiation exposure on the chemical composition of tobacco leaves, which provided a scientific basis for the quality identification of tobacco leaves, and provided a reference for the regional positioning and production area layout of high-quality characteristic tobacco leaves.
