【目的】调查研究恩施茶区土壤及茶叶中硒含量，为湖北茶产业发展提供参考。【方法】采集了湖北恩施地区93个茶园的土壤和茶叶样品，检测了土壤 pH 值、土壤和茶叶中的硒含量。【结果】恩施地区的土壤全硒含量总体水平较高，变幅为0．13～43．50 mg／kg，平均含量为1．52 mg／kg，高于全国土壤元素平均值（0．1 mg／kg），属富硒土壤；茶叶样品的硒含量变幅为0．040～1．03 mg／kg，平均硒含量为0．16 mg／kg，高于全国平均值（0．08～0．12 mg／kg）。土壤中 pH 值范围在4．5～5．5时，土壤全硒含量与茶叶硒含量呈显著相关（r≥0．90）。【结论】恩施茶园大多为富硒茶园，茶园土壤 pH 值保持在4．0～5．5区间有利于茶树对土壤中硒的吸收。

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 indus-try.[Method]Ninety three samples of soil and tea were collected in Enshi district,Hubei Prov-ince,and soil pH value,selenium content were analyzed.[Results]The Descriptive statistics in-dicated that the selenium content in soil was high in general,it ranged from 0.13 to 43.5 mg/kg, and the average content was 1.52 mg/kg,much higher than the average soil selenium content in China (0.1 mg/kg).The range of selenium content in tea samples were 0.04~1.03 mg/kg,and the average content was 0.16 mg/kg,higher than the average tea selenium content in China (0.08~0.12 mg/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 al-most belong to the selenium-rich soil in Enshi district,Hubei Province.It is atvantage for the ab-sorption of selenium in the soil when the soil pH ranged from 4.0~5.5.
