Abstract: The contents of fluoride in tea leaves and the distribution of fluoride in tea garden soils as well as their relationships were discussed in this paper by sampling the tea leaves and soils from the twelve tea gardens located South Center and Southwest China. The contents of fluoride in tea plants ranged from 221 mg/kg to 1504 mg/kg for old leaves and 49.0 mg/kg to 602 mg/kg for young leaves, respectively, the fluoride contents in old leaves were 2.5-8.1 times higher than that in young leaves. There were not a unified changing tendency for each form of fluoride in different soil layers, but the concentrations of different F forms for each soil layer were all in the order of residualFe-Mn oxide＞organic＞water＞exchangeable. The distribution of fluoride in tea garden soils was obviously related to the soil properties. The concentrations of fluoride in the tea leaves increased significantly with the water soluble fluoride, but other forms of fluoride were not of the same correlations with the contents of fluoride in tea leaves.
