湖南邵阳烟区气候特点及其对优质烤烟生产的影响

Climate characteristics and its effects on production of good quality flue-cured tobacco in Shaoyang,Hunan

对近30年来湖南邵阳烟区隆回县的气象资料(包括温度、光照和降雨)进行分析,结果表明,邵阳烟区具备优质烤烟生产大田期所需的良好温度、光照和降雨条件,是湖南省发展优质烤烟的较好产区,但在不同时期也存在一些不利于烟草生产的条件。针对这些制约烤烟生产的气候因素,提出了相应的烟草栽培关键技术要点,以期为邵阳特色烟叶生产提供技术支撑。

The climate characteristics,viz.,temperature,sun light and rainfall,in tobacco production areas of Shaoyang,Hunan in the recent 30 years have been analyzed comprehensively.During the study period,temperature,sunlight and rainfall conditions in tobacco producing areas of Shaoyang were found suitable for production of high-quality flue-cured tobacco.Though,Shaoyang is one of the best planting areas for production of high-quality flue-cured tobacco leaves in Hunan,it has some disadvantage also at different growth stage of tobacco production.Based on the eco-environmental conditions,which restricts the development of flue-cured tobacco production,some cultivation techniques had been put forward to provide support for producing good quality tobacco leaves in Shaoyang.
