Abstract
The F content in tea leaves,and total soil F and soil soluble F in ten FengHuang Tea Gardens of East Guangdong Province were determined.The results showed that the F contents in tea leaves were between 66.25-412.10 mg kg-1,with average of 238.2 mg kg-1.The content of total soil F was 400-450 mg kg-1,lower than the soil F background in the whole country(453 mg kg-1).The soil soluble F was between 0.20-0.50 mg kg-1.The high positive correlation was found between the F content in tea leaves and water soluble F.In addition,we found that the water soluble F content presented high positive correlation to the soil pH,and the contents fo exchangeable iron Ca,Mg,K and Na.On the contrary,the highly negative correlation was observed between the water soluble F and the contents of organic matter and the exchangeable Mn.
