摘　　要：以大红袍等10个茶树品种的种植土壤为研究对象,比较不同品种间土壤理化性质及土壤酶活性,以期探讨茶树品种对茶园土壤理化性质及土壤酶活性的影响。土壤理化性质研究结果表明,不同品种茶树土壤间N、P、K全量和有机质含量差别较小,但碱解N、速效P与速效K含量差异较大,大红袍土壤中速效K和碱解N水平明显低于其他品种土壤,水仙和白鸡冠土壤的pH值明显低于其他茶树品种的种植土壤。土壤酶活性研究结果表明,茶树种植提高了土壤酶活性,不同品种茶树土壤间10种土壤酶的活性变化较大,均达到中等程度变异水平。10个品种茶树对土壤酶活性的影响程度依次为:水金龟>奇兰>肉桂>矮脚乌龙=大红袍>半天妖>黄旦>水仙>白鸡冠>佛手。The cultivated soils of 10 tea varieties such as Dahongpao were used as the research objects to compare the soil physical and chemical properties and soil enzyme activities among different tea varieties,in order to explore the effects of tea varieties on soil physical and chemical properties and soil enzyme activities in tea plantations.The results of soil physicochemical properties showed there was little difference in the contents of total N,P,K and organic matter among the cultivated soils of different tea varieties,but the contents of alkali -hydrolyzed N,available P and available K varied greatly.The levels of available K and alkali -hydrolyzed N in Dahongpao cultivated soil were obviously lower than those of other varieties.and the pH values of the cultivated soils of Shuixian and Baijiguan varieties were significantly lower than those of other tea cultivars.The results of soil enzyme activities showed that tea planting improved soil enzyme activities, and the activities of 10 soil enzymes changed distinctly in cultivated soils of different tea varieties,reaching a moderate level of variation.The effects of 10 tea varieties on soil enzymes activities were as follows : Shuijingui > Qilan > Rougui > Aijiaowulong = Dahongpao > Bantianyao > Huangdan > Shuixian > Baijiguan > Foshou.
