贵州省丹寨县茶叶气候适宜性研究

         

摘要

By using the meteorological observation data such as temperature, precipitation, relative humidity, total cloud and foggy days in Danzhai County during 1981-2010, starting from climatic conditions of tea production, main meteorological disasters in tea production peri-od, meteorological indicators for producing high quality tea in Danzhai were summarized and climate characters were analyzed.The results showed that the solar-thermal resources are rich, the moisture condition is appropriate, there are obvious climate advantages for tea growth in Danzhai County;drought, flood disaster, high temperature heat damage, low temperature freeze injury and other disasters were lighter, protec-tion of eco-environment was good, there was no pollution from large-scale chemical enterprises, which are conductive to the production of high-quality tea.The major adverse climate was summer drought, but the influence of summer drought was lighter compared with tea produc-tion area in eastern coast of China.%利用丹寨县1981~2010年气温、降水、空气相对湿度、天空总云量以及雾出现日数等气象观测资料,从丹寨县茶叶生产的气候适宜条件、茶叶生产期内主要的气象灾害入手,归纳出丹寨生产优质茶叶的气象指标,分析丹寨优质茶叶的气候特征。结果表明,丹寨县茶树生长的光热资源丰富,水分条件适宜,光热水匹配良好,气候优势明显;多云雾天气,干旱、洪涝灾害、高温热害、低温冻害等灾害较轻,且生态环境保护好,无大型化工企业污染,有利于优质茶叶的生产。主要不利气候是夏季伏旱,但伏旱的影响相较于我国东部沿海茶叶生产区较轻。
