Abstract:

Climate is the one of the most important ecological conditions to the flue-cured tobacco. For grasping the relationships between Yunnan flue-cured tobacco chemical quality and the climate conditions in flue-cured tobacco field birth periods and making it clear about climate ecological foundation of Yunnan flue-cured tobacco chemical quality, the correlation and regression analysis were used to analyze the climate data and flue-cured tobacco chemical quality in Yunnan Province in 2004. While taking advantage of AHP was given a comprehensive evaluation of the results of flue-cured tobacco and conduct a preliminary analysis of the relationship with weather conditions, and regression equation. The results showed that analysis of the quality of flue-cured tobacco was compelling; Yunnan flue-cured tobacco quality had the close relationship with the precipitation and sunshine hours in April and May, which play a leading role in precipitation.
