摘　　要：采用土培法比较研究了不同质量浓度的铝、氟胁迫及交互作用对2种不同基因型茶树——白茶和智仁早茶根际土壤微生物区系的影响.结果表明:低水平的Al或F处理对2种茶树根际土壤细菌、放线菌的生长繁殖以及呼吸强度有一定的刺激作用,高水平的Al或F处理对这些微生物则表现为明显的抑制作用;高水平的Al或F处理对真菌表现为促进生长的作用.统计分析显示,Al和F在茶树根际土壤中存在交互作用,对不同微生物的影响各不相同.Investigations were conducted on the soil rhizosphere microbes of two kinds of tea plant ＂white tea＂ and ＂Zhirenzao tea＂ under stress of aluminum and fluorine. Interactive effects of aluminum toxicity and fluorine were studied. The results showed that low concentration of aluminum and fluorine treatment had influence on them, and it also implied that there were significant differences between these two varieties tested. It indicated that low concentration of aluminum and fluorine exerted a positive effects on increasing of the population quantity of rhizosphere microbes significantly, such as bacteria, actinomycetes, it suggested that appropriate concentration of Al and F could promote the growth and propagation of these microbes above ; while high concentration of Al and F had a negative effects on them, except fungi. When treated with both highest concentration of Al and F, population quantities of these microbes above all were not as small as treated by separate highest concentration of Al or F each, but a little more, which indicated great significant interaction between aluminum and fluorine.
