摘要： 江苏宜兴茶园中,F、Al、Mn、Fe等元素在茶树叶中呈较强的富集化现象.茶树年吸收量最大的元素是Mn,其次为Al、Fe和F;茶树年归还量最大的元素为Mn,其次为Al、F和Fe;茶树吸收系数最大的为F。其次为Mn,利用系数和循环系数最大的也是F,元素F的循环周期最短,Cr循环周期最长.

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.
