| Abstract: | The paper studies the relationship between the content of Se and As in the Enshi Se-rich tea,and that between the content of Cd and U in the corresponding soil samples,with the purpose to provide the best planting conditions of the Se-enriched tea.Through the determination of Se and As in the tea samples from Yulu tea garden by slope and the corresponding soil samples by AFS,the following conclusions are drawn.1) In the range of 0.40-1.50 mg/kg,the Se concentration in the tea shows a trend to rise first and... |
