Abstract: [Objective] The objective of this study was to investigate the selenium element in tea plantation of Enshi district, Hubei province, and provide a reference for development of tea industry. [Method] Ninety three samples of soil and tea were collected in Enshi district, Hubei Province, and soil pH value, selenium content were analyzed. [Results] The Descriptive statistics indicated that the selenium content in soil was high in general, it ranged from 0.13 to 43.5mg/kg, and the average content was 1.52mg/kg, much higher than the average soil selenium content in China (0.1mg/kg). The range of selenium content in tea samples were 0.04~1.03mg/kg, and the average content was 0.16mg/kg, higher than the average tea selenium content in China (0.08~0.12mg/kg). As the soil pH of ranged from 4.0~5.5, the selenium content between the soil and the tea were significantly correlated (r≥0.90). [Conclusion] The soil in the tea plantation almost belong to the selenium-rich soil in Enshi district, Hubei Province. It is atvantage for the absorption of selenium in the soil when the soil pH ranged from 4.0~5.5.
