摘要：

通过采集云南省代表烟区烤烟样品和收集相关地点气象资料，应用灰色关联分析原理分析云南烟区烤烟化学成分与30个气象因子之间关联度。结果表明，云南烟叶质量稳定性和化学成分均衡性较好。碱含量与成熟期的平均气温的关联度最大。总糖含量与旺长期平均日照时数和平均日照全辐射的关联度最大。还原糖含量与气象因子的关联度和总糖基本一致。总氮含量与成熟期平均气温关联度最为密切。钾含量与成熟期平均相对湿度有较高关联度。氯含量与团棵期的平均相对湿度关联度最大。可见，大田期的平均气温、团棵期的平均相对湿度和成熟期平均日照时数是影响烤烟化学成分积累的关键气象因子。

Abstract:

To study the relevance between formation of characteristics of Yunnan tobacco and different meteorological factors, by collecting flue-cured tobacco samples and collecting related sites’ meteorological data of Yunnan Province, using principles of gray relational analysis correlation between chemical composition of tobacco samples and 30 meteorological factors of Yunnan. The results showed that the stability and chemical quality of tobacco in Yunnan were good. Content of nicotine had high relevance with the mature period average temperature. Content of total sugar had the higher relevance with the average sunshine hours and average sunshine whole radiation of June. The relevance between reducing sugar and meteorological factors had the consistent result with total sugar. Content of total nitrogen had the highest relevance with the mature period average temperature. Content of K had the higher relevance with average relative humidity of the mature period. Content of Cl had the higher relevance with average relative humidity of May. It can clearly be seen, average temperature of May to September, average relative humidity of May and average sunshine hours of the mature period were the key meteorological factors which affect the chemical compositions accumulation of flue-cured tobacco.
