This paper tallied up that the distribution of plinthitic red paleosol is just coincide with the tea in the area north of Yantze River(Fig.1).Moreover, there are two tea areas outside of the red earth zone on the distributional map (Rizhao area in Shangdong Province. And Chayu area in Tibet)。It can be recognized that both of them had been influenced by the red paleosol on the soil property. All of these showed that the red paleosol could promote the tea plant growth.Therefore the influences of the red paleosol should not be negnected on the study of tea garden soil.
