The tea plant （Camellia sinensis） cultivar ‘Zhuyeqi' was subjected to four levels of artificial shading including 0%， 50%， 75%， and 80% to study the effects of different intensities and durations of artificial shading on the accumulation of water-soluble fluoride in tea plants during the summer and autumn seasons. Samples of soil in tea garden and various tissues including leaves， stems， roots of tea plants were collected on the 10th， 20th， 30th， and 40th day after treatment to determine the content of Ws-F. The results showed that artificial shading significantly promoted the accumulation of Ws-F in processed tea. The content of Ws-F in tea leaves with artificial shading increased significantly with the increase of the intensity of artificial shading compared with that in tea leaves without artificial shading. The balance of fluoride within the tea plants was disrupted when the intensity of artificial shading reached 80%. It was found from further analyses that the prolonged artificial shading may induce the transport of fluoride from young leaves to older leaves. It is indicated that artificial shading significantly increases the accumulation of Ws-F in summer-autumn tea， and there are complex interactions between the intensity and duration of artificial shading. It will provide valuable insights for the safe production of tea during the summer and autumn seasons.
