| 摘 要： | 对湖南5个主产烟县(市)35份烟叶样品的部分化学成分与烟样产地的31项主要气象因素进行了单回归及逐步回归分析.得出的主要结论为:影响烤烟总糖含量的主要是烟季≥10 ℃活动积温、烟季日照时数;影响烤烟钾含量的主要是烟叶成熟期气温日较差、烟季第3月均降水量和第4月均温;影响烤烟糖碱比的主要是烟季150 d≥35 ℃天数、第3月均降水量和采烤期积温.

| Abstract: | Partial chemical components of 35 flue-cured tobacco leaf samples from 5 mainly production counties(city) and 31 main datum of climatic factors in Hunan were generally analyzed with single regression and gradual regression analysis.The results showed that it was the temperature accumulation of ≥10 ℃ and shining time in tobacco season that mainly influenced total sugar of flue-cured tobacco.Main climatic factors influencing tobacco potassium content was day temperature deduction in tobacco leaf maturity period,average rainfall in the 3rd month and average temperature in the 4th month of tobacco season.The number of 150 days with T≥35 ℃ in whole duration of tohacco growth,average rainfall in the 3rd month and temperature accumulation in harvesting period were main factors influencing the ratio of sugar to nicotine of flue-cured tobacco. |
