In order to study the translocation and accumulation of zinc(Zn)in soil and tea tree system under actual production conditions，1478 soil samples and 130 sets of tea samples were collected in the Xianfeng county. The contents of Zn，constant oxide，organic carbon and pH value in soil，as well as the contents of heavy metals and Zn in different parts of tea plant were determined. The correlation analysis of Zn content in soil and tea was carried out，and the influencing factors of Zn biological absorption coefficient were studied. The results showed that the average Zn content in tea soil was 92.14 mg/kg，which was higher than the mean abundance of 69 mg/kg in China. For the profile distribution，the contents of Zn increased or first decreased and then increased with the depth increasing. The soil Zn was mainly in the form of residue，followed by the humic acid binding state and iron and manganese oxides，together accounting for 84.35% of the total pool. The proportion of average bio-available Zn content was relatively small(water-soluble Zn and ion-exchange Zn accounted for 2.73%). The average Zn content in tea was 37.41 mg/kg，and the range of bioconcentration factor was 15.95%-92.94%. According to the Zn content and bioconcentration factor，different parts of tea plant were ranked as tender leaves>roots>stems>old leaves，which indicated that Zn was easily to enrich in tea under actual production conditions. The correlation analysis showed that soil organic carbon content had significant positive correlation with available Zn content. Soil constant oxide and pH value had opposite effects on Zn and bioavailability of Zn in soil. Factors such as high pH degree，soil with low SiO₂ content and high Fe2O3 and Al2O3 content could promote the accumulation of Zn in soil，but also limited the activity of available Zn.
