福建三明地区烤烟生长期气候特征分析

[目的]分析三明地区烟草生长期间温度、降雨和日照等气候特征及其对烟草生产的影响。[方法]根据不同项目的分析要求，对三明市各县的累（历）年气象观测结果进行统计计算。[结果]三明地区各县1～7月的月平均气温基本上为17～19℃。三明地区各县的月平均降水量为150～210mm，且从1月开始逐渐增加，至6月达到最大，总降水量在1000～1500mm之间，北部降水量多于南部。三明地区各县的空气平均相对湿度依次是：永安（77．5％）〈大田（80．1％）〈沙县（81．3％）〈宁化（82．0％）〈将乐（82．1％）=明溪（82．1％）〈建宁（83．1％）=尤溪（83．1％）〈清流（83．4％）〈泰宁（85．9％）。三明地区1～7月的月平均日照时数为107．4～131．2h，日照总时数为751．5～918．4h。[结论]三明地区的气候条件比较适宜于烤烟生产，三明地区可作为CB-1烟叶的主要生产地。

Analysis on the Climatic Characteristics of Sanming Area in Fujian Province in the Growing Period of Flue-cured Tobacco

[ Objective ] The purpose was to analyze the climatic characteristics such as temperature, rainfall and sunshine of Sanming area during the growing period of tobacco and their influences on tobacco production. [ Method] According to analysis requests of different projects, the cumulative annual meteorological observation results of counties in Sanming City were calculated statistically. [ Result] The monthly average temperatures of counties in Sanming area from Jan. to July were 17 - 19 ℃ basically. Their monthly average precipitations were 150 -210 mm, began to increase gradually from Jan. , reached its maximum till June and the total precipitation, which was more in the northern than that in the southern, was between 1 000 and 1 500 mm. The average relative air humidities of counties in Sanming area were as follows in sequence： Yong＇an （77.5%） 〈 Datian （80.1%） 〈 Shaxian （81.3%） 〈 Ninghua （82.0%） 〈 Jiangle （82.1%） = Mingxi （82.1%） 〈 Jianning （83.1%） = Youxi （83.1%） 〈 Qingliu （83.4%） 〈 Taining （85.9%）. The monthly average sunshine hours of Sanming area from Jan. to July were 107.4 - 131.2 h and its total sunshine hours were 751.5 - 918.4 h. [ Conclusion] The climatic condition of Sanming area was relatively suitable for producing flue-cured tobacco and it could be used as the main producing area of CB-1 tobacco leaves.
