Abstract: The biological cycle characters of ten elements in the artificial tea garden ecosystem in Yixing County, Jiangsu Province is studied in this paper. The results obtained from experiments and analysis reveal that:(1) the contents of ten elements are different a-mong various parts of the tea plant, and F, Al,Mn, Fe have the characters of accumulation in the leaves;(2) in all elements, Mn has the largest absorption amounts and return amounts annually;(3) F has the largest utilization coefficient and cycling coefficient;(4) F has the smallest turn period and Cr has the longest.
