Abstract:

To clarify the climate characteristics of tobacco planting in Qianxinan of Guizhou, the temperature, precipitation and sunshine duration of tobacco field period in different months were selected, and then comparative study, similarity analysis and cluster analysis were used to study the difference and similarity of climate in tobacco field period between the region with major domestic and overseas tobacco-growing areas. The results show that: the average daily temperature in Qianxinan of Guizhou during tobacco field period is above 20℃, the precipitation is above 900 mm, and the sunshine hours are over 700 hours. It has the characteristics of moderate daily average temperature, more precipitation, sunshine and warmth, and has the basic conditions and advantages of high quality tobacco planting. The climate of tobacco field period in the region is moderately similar to Zunyi, Yuxi and Longyan in China, but less similar to Chenzhou in China and tobacco planting areas in Brazil and Zimbabwe. The climate of tobacco field period in Zhenfeng County is quite different from that in other five counties (cities) of the prefecture. Thus, the monthly average meteorological factors in the tobacco field period can better clarify the climate characteristics of the tobacco area.

Key words: field period of flue-cured tobacco, climate, similarity analysis, cluster evaluation, tobacco growing areas in Qianxinan of Guizhou
