典型香型烤烟大田期气象因子分析

Analysis of Climatic Factors for Flue-cured Tobacco of Typical Flavor Type at Field Stage

为了明确影响烤烟不同香型风格形成的关键气象因子,以我国主产区典型香型烤烟为研究对象,运用数理统计方法对观测样本进行了分析。结果表明:1不同香型间气象因子的差异主要表现为区域气候因素;2大田期不同气象因子的差异更多地表现为以季节性为主的温度、湿度、水汽压等因素;3不同香型和大田期气象因子的交互作用差异主要为光照。因此,在烟草生产中应充分考虑气象因子的差异,优化资源配置为烟叶品质提高和风格彰显提供良好条件。

In order to find out the key climatic factors influencing the formation of flavor type of flue-cured tobacco, the samples of flue-cured tobacco of different typical flavor types were collected from the main tobacco planting areas in China and analyzed with mathematical statistics. The results showed that： 1）the difference in climatic factors between different flavor types was mainly attributed to regional climatic factors; 2） the difference of climatic factors at field stage was mostly of seasonal dependence such as temperature, humidity, vapor pressure, ere; 3） the difference of interaction between climatic factor and flavor type at field stage was mainly caused by light irradiation. Therefore, the difference of climatic factors should be taken into full account in tobacco production and the resources should be rationally assigned to improve the quality andstyle of tobacco.
