摘　　要：[目的]明确南雄烟区主要气象因子对烟叶烟碱含量的影响。[方法]收集南雄烟区2011—2020年主要气象资料及烟叶烟碱含量数据,分析近10年南雄烟区烤烟大田期主要气象因子和烟叶烟碱含量,对主要气象因子与烟叶烟碱含量进行相关性分析。[结果]3月上旬降雨量与中部烟叶烟碱含量呈显著负相关;伸根期降雨量与中部烟叶烟碱含量呈极显著负相关,与上部烟叶烟碱含量呈显著负相关。[结论]针对南雄烟区伸根期降雨量偏多的状况,可采取高起垄、高培土、深挖沟等措施,排除田间积水,促进根系生长发育,以提高烟叶烟碱含量。[Objective]In order to define the effects of major climatic factors on nicotine content of tobacco in Nanxiong tobacco area.[Method]The main meteorological data and nicotine content data of tobacco leaves in Nanxiong tobacco area from^(2)011 to 2020 were collected,the main meteorological factors and the nicotine content of tobacco leaves in the field period of flue-cured tobacco in Nanxiong tobacco area in the past 10 years were analyzed,and the correlation analysis between the main meteorological factors and the nicotine content of tobacco leaves was carried out.[Result]The precipitation in the first ten days of March was significantly negatively correlated with the nicotine content of the central tobacco leaves;the precipitation during the root extending stage was extremely significantly negatively correlated with the nicotine content of the central tobacco leaves,and significantly negatively correlated with the nicotine content of the upper tobacco leaves.[Conclusion]In view of the high precipitation during the root extending stage in Nanxiong tobacco area,the measures such as high ridges,high soil cultivation,and deep trenches can be taken to remove the accumulated water in the field and promote the growth and development of the root system,so as to increase the nicotine content of tobacco leaves.
