摘　　要：通过对安吉白茶产地地质、地球化学特征的系统研究,认为成土母岩、土壤元素组合等对茶叶的品质均具有深刻的影响。母岩(母质)类型不同,土壤类型、质地、pH值,尤其是土壤地球化学成分就会具有很大的差异,钾、硅、铝和酸性土壤有利于茶叶生长发育,钙、镁、钠和碱性土壤不利于茶叶品质的提高。茶叶硒、锌含量高,其生化成分与土壤中钾、钼、锰、硫、磷的有效态呈显著正相关。因此,建议发展白茶基地应在安吉中部、东部低山丘陵区,选择以石英砂岩、岩屑砂岩风化残坡积物为母质的土壤。Based on the characteristics of geology and geochemistry, the Anji white tea in producing area was studied. The results show that parent rocks and chemical element combination in local soil have influenced deeply composition and characters of them. Because of different rock types, soil types, texture and pHs of the soils differ also, especially chemical elements of soils. K, Si, A1 and acid soil markedly promote the growing and upgrowth of tea, and Ca, Mg, Na and alkaline soil make against boosting of tea quality. The leaves have high Se and Zn contents, and there is a pronounced positive correlation between biochemical composition of tea and their corresponding effective contents of K, P, S, Mn in soils. Therefore, this paper gives a suggestion that Anji white tea should be grown where sandstone-parent rock is distributed, in hilly country and mountain, east- ern and middle part of Anji County.
