The concentration of aluminum (A1) and fluorine (F) in tea plant and its implication on human health have been a topic of concern,since tea is an Al and F accumulator,and may contain Al and F high concentration in old leaves.Soil microorganisms are main components of soil biochemical properties,they are reported to be the most important factors in soil of plant,especially the microorganisms,and they have become one of important target evaluating the soil.However,a lot of investigations have been done on only Al or F effects on tea plant,but few has been done upon the stress of interaction of both on tea plant,and that on rhizosphere microbes at home and abroad.The dynamic state of rhizosphere soils related to roots and microbes were investigated with two varieties of tea,white tea and zhirenzao tea,in order to understand the effects of interaction of aluminum and fluorine stress on soil microbes of tea rhizospher.The results indicated that low concentration of aluminum and fluorine exerted a positive effects on increasing of the population quantity of rhizosphere microbes,such as bacteria,actinomycetes,azotobacter,ammonifying bacteria,nitrobacteria,denitrobacteria,so as to breath intensity; while high concentration of aluminum and fluorine had a negative effects on them,when aluminum arrived 400 mg/kg and fluorine arrived 120 mg /kg,the inhibit attained the highest value.The number of epiphyte increased with the growth of concentration of aluminum,which is not related to fluorine.The results also showed that azotobacter and ammonifying of these two species were both sensitive to interaction of aluminum and fluorine stress,however,white tea was more sensitive.The results also indicated that soil microbial quantity and activity of soil enzymes varied with growing stages.Microorganisms and enhanced activity of soil enzymes was related to improved tea plant growth and development,status of tea growth and development exerted influence on soil microorganism population and enzyme activity.Soil microbes were key factors for maintaining soil quality.Based upon above analyses; it could be concluded that the soil stabilizer was helpful for conversion and accumulation of soil organicmatter,improvement in soil fertility,and had no negative influence on soil chemical properties.
