云南省烤烟气候地区差异性

Study on the Difference of Climate during Flue-cured Tobacco Field Growing Period in Yunnan Province

利用相关分析、方差分析、多重比较等多种统计方法,系统分析了云南省烤烟气候条件及区域间的差异性。同时,利用系统聚类以烤烟大田生育期的主要气象指标为影响因素对不同区域进行分类,并概括出不同区域的气候特征。结果表明:云南烤烟大田生育期间的主要气象指标间存在密切的关系,州(市)间烤烟气候条件总体差异明显,部分区域有一定相似性。初步把云南16个州(市)分为4类,其中玉溪、楚雄、曲靖、文山、昆明、大理、红河、丽江、昭通为一类,此区域光温水条件适宜,非常适合优质烤烟生长;普洱、保山、西双版纳、德宏、临沧为一类,此区域雨水较多,光热资源丰富,可生产具有特色的优质烤烟;怒江为一类,此区域温度和降雨适宜,日照偏少,不利于优质烟叶品质形成;迪庆为一类,温度过低,热量不足,不适宜烤烟生长和品质形成。

Using correlation analysis, variance analysis and multiple comparisons to analyze the climate conditions of Yunnan flue-cured tobacco and its difference of vary area. At the same time, using the system cluster to classify the different area by main climate indexes during flue-cured tobacco field period and generalizing its climate characteristic. The results showed that there were close relationships between the main climate indexes of flue-cured tobacco field period. Total climate condition difference between cities was obvious, but part area had certain comparability. 16 cities were divided into 4 types. Thereinto, Yuxi, Chuxiong, Qujing, Wenshan, Kunming, Dali, Honghe, Lijiang and Zhaotong were one type. The sunlight, temperature and rainfall condition of this region were suitable for high quality flue-cured tobacco growth. Pu＇er, Baoshan, Xishuangbanna, Dehong, Lincang were one type. The more rain water and enough sunlight and heat resources of this region were suitable for the characteristic quality flue-cured tobacco growth. Nujiang was one type. The temperature and rainfall of this region were suitable, but the sunlight was few, so the condition didn＇ t favor the high quality formation; Diqing was one type. The excessively low temperature and insufficient heat were not suitable for the flue-cured tobacco growth and the quality formation.
