为了全面掌握云南烤烟化学品质与烤烟大田生育期间主要气象条件的关系,明确云南烤烟品质形成的气候生态基础,本研究利用方差分析、相关分析和回归分析等方法,对云南省2005年至2007年气象数据和烤烟化学品质数据进行统计分析。结果表明,云南烤烟主要化学成分及协调性指标和大田期主要气象指标在12个植烟州(市)之间有明显差异。云南烤烟化学成分及协调性指标与大田主要气象指标关系较为密切。其中总糖含量、还原糖含量、糖碱比与4～9月总降雨量、4～9月总日照时数、7～8月总日照时数关系密切;总氮含量与4～9月总降雨量关系密切;烟碱含量与4～9月总日照时数、7～8月总日照时数、4～9月总降雨量、4～9月平均气温关系密切;K+含量、钾氯比与4～9月总降雨量、7～8月平均气温关系密切;pH值与7～8月总日照时数、4～9月总日照时数关系密切;两糖差与4～9月平均气温关系密切;C l-含量与4～9月总降雨量关系密切。
In order to comprehensively understand the relationship between the chemical quality of flue-cured tobacco and the main meteorological conditions during flue-cured tobacco growing in Yunnan Province, and to determine the climatic and ecological basis for the quality of flue-cured tobacco in Yunnan Province, this study used variance analysis, correlation analysis and regression analysis, Meteorological data and chemical quality data of flue-cured tobacco for statistical analysis. The results showed that the main chemical components and coordinative indexes of Yunnan flue-cured tobacco and the main meteorological indicators in the field were significantly different among 12 tobacco producing states (cities). The chemical composition and coordination index of Yunnan flue-cured tobacco are closely related to the main meteorological indicators in the field. The contents of total sugar, reducing sugar and ratio of sugar and alkali were closely related to the total rainfall from April to September, the total sunshine hours from April to September and the total sunshine hours from July to August. The total nitrogen content was similar to that from April to September There was a close relationship between rainfall and nicotine content. The content of nicotine was closely related to the total sunshine duration from April to September, the total sunshine hours from July to August, the total rainfall from April to September and the average temperature from April to September. K + content, Which was closely related to the total rainfall in April and September and the average temperature in July and August. The pH value was closely related to the total sunshine hours from July to August and the total sunshine hours from April to September. The difference between the two sugars and the average from April to September The temperature is closely related; C l-content is closely related to the total rainfall from April to September.
