Abstract: The objective of this study was to investigate distribution characters of soil nutrient and soil hardness in the tea gardens of Anhui Province. Understanding the linkage between soil nutrient supply and tea plant nutrient contents is helpful to improve the management of hill tea gardens．Results indicated that the soil chemical properties at upper and lower depths，the nutrient traits in various plant modules and their relationships were studied in tea gardens of different districts. Chemical properties of various pH field have notable difference, Specially when soil pH fall in 4.0~4.5 field the rest raining capacity to process of acidification weaken in evidence and velocity of loss of electro positive particle will increase too. When soil pH fall beyond 5.0 field the rest raining capacity to process of acidification enhance in evidence. The content of N and P were high, K was poorer in Southern Anhui, contents of N P K contents were relatively uniform in West Anhui. pH value were very low and showed the trend of acidification aggravation gradually, soil pH below 4.5 account for more than 50% of tea gardens. The soil bulk density were 1.32～1.47g/cm3 at the layer of 0～20 cm and 1.37～1.58g/cm3 at 20～40 cm, soil porosity was 50% approximately, air phase were not enough, the permeability of soil was bad. There is great difference in the fertilization level of Anhui districts, fertilizer application rate in Southern Anhui were higher than West Anhui by15%.
