摘要
为了研究烤烟烟叶焦甜香香韵形成与气象因素之间的关系,以全国15个植烟区域的C3F为研究对象,运用相关、回归和判别分析对两者之间的关系进行了统计分析。结果表明,烤烟烟叶焦甜香香韵的形成与极端最高温、极端最低温、降水量、平均气温、日照时数、最大风速、最小相对湿度7个因素存在显著的回归关系,且对焦甜香风格形成的影响程度依次为:极端最高温>最小相对湿度>降水量>日照时数>平均气温>极端最低温>最大风速。以此7项指标建立的判别函数判别植烟区域焦甜香香韵的有无准确率较高。因此,在焦甜香烟叶生产过程中可以优化资源配置,适应以此7项指标为主的生态特点,为烟叶生产提供良好充分的适应条件。
In order to explore the relationship between cause of coke sweet aroma in tobacco leaves and climatic factors, correlation, regression, and discrimination analysis were conducted for aroma of C3F tobacco leaves from 15 locations in China. The results showed that there was significant relationship between coke sweet aroma and extreme high temperature, extreme low temperature, sum rainfall, average temperature, sunshine hours, maximum wind speed, and minimum relative humidity. The strength influencing coke sweet aroma type was, in the order of decreasing, extreme high temperature〉extreme low temperature〉sum rainfall〉average temperature〉sunshine hours〉maximum wind speed〉minimum relative humidity. The discrimination analysis results predicted the predictors both correctly based on such 7 climatic factors. So some methods could be taken to improve the tobacco quality and style during the tobacco production.
