摘　　要：为明确湖北烤烟主要化学成分与大田期气候因子的关系,探讨烟区间差异,利用烤烟化学成分、大田期时段和气象数据,采用数理统计分析。结果表明:影响湖北烤烟烟碱含量、总糖含量、氮碱比、糖碱比的主要气候因子为成熟期降水量,影响还原糖、总氮、钾含量的主要气候因子分别为旺长期的相对湿度、降水量、日照时数,影响氯含量、两糖比、钾氯比的主要气候因子分别为成熟期的日照时数、气温日较差、平均气温;湖北烟区大田期气候存在一定差异,采用SOM神经网络进行聚类分析可划为两类,两类气候的烟区与根据种植区域划分的“金神农”和“清江源”烟区一致;旺长期的日照时数、相对湿度、成熟期的日照时数、平均气温分别是影响两类烟区钾含量、还原糖含量、氯含量、钾氯比差异的主要气候因子。To clarify the relationship between main chemical components of flue-cured tobacco in Hubei tobacco-growing areas and climatic factors in field period,and differences of tobacco areas,the mathematical statistics were used to analyze the chemical composition,field growth period and meteorological data.The results showed that the precipitation during maturing stage was the leading climatic factor affected nicotine,total sugar,nitrogen-alkali ratio and sugar-alkali ratio.The main climatic factors that affected reducing sugar,total nitrogen and potassium were relative humidity,precipitation and sunshine duration during fast growing stage,respectively.Sunshine duration,diurnal temperature range and average temperature during maturing stage were the main influencing factors for Chlorine,ratio of two sugars and potassium-chlorine ratio,respectively.There were differences in the climate during the field growth period in Hubei tobacco-growing areas,the climate type could be divided into two categories by clustering analysis based on SOM neural network,and the tobacco-growing areas of two climates were consistent with the division of“Jinshennong”and“Qingjiangyuan”tobacco-growing areas according to planting regions.The main climatic factors that affected the differences in potassium,reducing sugar,chlorine and potassium-chlorine ratio in the two types of tobacco areas were sunshine duration during fast growing stage,relative humidity during fast growing stage,sunshine duration during maturing stage and average temperature during maturing stage,respectively.
