This paper analyzed the physical property, pH value and nutrient of the soils of Jiuhuashan, Guniujiang and Xianyushan tea gardens by comparison and study. The results showed that the soil parental material of Jiuhuashan、Guniujiang and Xianyushan tea garden mainly resulted from the granite and the shale. The tea garden soil was consisted of the loam. Its soil bulk specific gravity was (0~40 cm) 1.22 g/cm3, soil gross porosity was 48.6%, fertile and deep; In the soil layer there were the average content of the organic matter, total nitrogen, the alkaline hydrolysis nitrogen, available phosphorus, available potassium, and they were 28.32 g/kg, 1.46 g/kg, 110.12 mg/kg, 11.48mg/kg, 73.55mg/kg, respectively; The pH value in 0~20 cm soil was average of 4.77, and in 20~40 cm soil was 5.48. The content of soil’s nitrogen, phosphorus, potassium is: Jiuhuashan＞Guniujiang＞Xianyushan, and of pH value: Guniujiang＞Xianyushan＞Jiuhuashan, which depends on its parental material, the soil structure, tea growing time, the tea garden management as well.
