Climatic Problems and Countermeasures of Planting Tobacco Zone in Xingyi of Guizhou

根据烤烟生长习性和最适宜气象指标,分析了贵州省兴义市光、温、水等气候资源的特点。结果表明:兴义市光照资源丰富,太阳辐射充足,日照时数长,有利于烤烟产量和品质的提高;良好的温度条件和水资源为烤烟生产的发展奠定了基础,早春气温回升较快,有利于烤烟的播种和移栽,后期较高的温度有利于烟叶成熟及采烤,但兴义烟区倒春寒、春旱、暴风及秋风、秋后绵雨等自然灾害频发。针对兴义市的气候特点,提出了对倒春寒、春旱等自然灾害天气的预防措施。

The characteristic of climate resources including ray,temperature and rainfall in Xingyi was analyzed according to the growing behavior of tobacco and the optimum weather index.The results indicated that the weather in Xingyi was benefit to the enhancing of the tobacco yield and quality.The ray and sun＇s radiation was richness.The sunlight time was long.Richer heat and rainfall was good foundation for tobacco production.It was benefit to seed and transplant because of the air temperature ascending quickly in early spring.The higher air temperature in later growth was fit to ripeness,picking and curing.The defending measure was suggested for disastrous climate such as early spring cold,spring drought,rainstorm,sharp autumn wind and continuous rain in later autumn.
