Abstract:

Using correlation analysis, variance analysis and multiple comparison 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.
