Soil chemical constituents of ancient tea gardens were determined and analyzed in Xishuangbanna, Puer, Lincang and Baoshan cities(prefectures),Yunnan province. The results showed that the contents of rapidly available N, P and K, organic matter, were 167.48, 13.57and 81.46 mg/kg,4.66 % respectively. The available contents of B, Ca, Mg, Fe, Mn, Cu and Zn were 1.07, 292.93, 47.2, 85.99, 20.72, 0.93 and 1.33 mg/kg respectively. The total contents of heavy metals of Cr, Pb and Hg were 74.28, 96.67 and 0.13 mg/kg. In conclusion, the contents of organic matter was more than of high quality tea garden and produce leval of first class soil in China at the moment. These contents were lower than that of high quality tea garden in rapidly available P, rapidly available K, available Cu and available Zn.
