本文总结了全国网纹红土分布与长江以北大部茶树分布恰相符合;又分析了脱离于红壤带之外的山东日照茶区、西藏察隅茶区,其土壤都有古红土的影响,说明了是古红土促进了茶树生长。虽然古红土和现代红壤的关系,至今在科学上还未完全解决,但从实际出发,研究茶园土壤,古红土的影响不容忽视。

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.
