Study On The Relationship Of Meteorological Factors And Tobacco Quality In Typical Tobacco Growing Area Of Guizhou

According to the tobacco producing counties in Guizhou style characteristics of tobacco and tobacco Guizhou embodies the principle focus of tobacco base, selected ten representative areas of Guizhou smoke point as a pilot study of the ten pilot sites which meteorological factors and the leaf quality indicators, and the relationships between them. The results showed that within the District of Guizhou Tobacco, tobacco aroma, pungent, taste, aftertaste, smoke photogenic powder degree and 6-9 month precipitation was significantly positively correlated with spring precipitation, May precipitation was significant negative correlation; aroma with the precipitation factor was a significant negative correlation, mixed gas and spring precipitation, May precipitation was significantly negative correlation. Aroma quality, smoke on the photogenic powder degree and sunshine, spring sunshine, sunshine seedlings also showed a significant positive correlation with the vigorous, mature sunshine was significantly negatively correlated; aroma and June, the total bright sunshine and the field of average sunshine was significantly negatively related to odor, irritation, taste, aftertaste and May according to the summer sun was significantly correlated with maturity sunshine was significantly negative. Aroma, pungent, taste, aftertaste, the degree and temperature factors photogenic powder smoke was significantly negatively correlated, aroma, mixed gas and most of the precipitation factor was a significant negative correlation. Meteorological factors there are 27 principal components, the intrinsic quality of the principal component of 14. The greatest impact on tobacco leaf quality key indicator of meteorological factors is May 6-July temperature, precipitation, August sunshine, sunshine, annual precipitation. Ward method used from the meteorological factors can be grouped into two categories, quality of tobacco can be grouped into two categories. Different geographical areas in the objective existence of different weather conditions, different quality of meteorological factors have different characteristics, meteorological factors and the quality of tobacco there is a clear correlation between meteorological conditions similar to the tobacco producing areas of the existence of similar quality, is also relatively close to the characteristics of tobacco.
