摘　　要：为研究贵州省主要茶区土壤酸性特征,对贵州省主要茶区及周边土壤样品pH值进行测定。结果显示,贵州主要茶区土壤pH自南向北呈逐渐增加趋势;贵州主要茶区土壤pH在垂直分布上存在差异,随土层加深土壤pH逐渐升高;从不同地区土壤平均pH值表现看,凤冈县>都匀市>湄潭县>贵定县;贵州省茶园土壤周边林地也适合茶树生长,植茶对贵州土壤酸性具有一定的调节作用。In order to study the acidic characteristics of soil in the main tea areas of Guizhou Province,the pH of soil samples from the main tea areas and surrounding areas were measured.The results showed that the soil pH of the main tea areas in Guizhou showed a gradually increasing trend from south to north;There are differences in the vertical distribution of soil pH in the main tea areas of Guizhou,and the soil pH gradually increases with the deepening of the soil layer;From the performance of average soil pH in different regions,Fenggang County>Duyun City>Meitan County>Guiding County;The surrounding forest land of tea gardens in Guizhou Province is also suitable for tea tree growth,and planting tea has a certain regulatory effect on soil acidity in Guizhou.
