Anxi is the largest producing area of Tie Guanyin tea in China. “The cultural system of Tie Guanyin tea in Anxi” was selected as “Nationaly Important Agricultural Heritage Systems” (China-NIAHS) in 2014. Tea gardens in this region are organic, ecological or non-ecological. After sampling the soil in these three kinds of tea gardens, we compared soil properties and nutrient content at different soil depths using physical and chemical analyses. Our aim was to provide a scientiifc basis for the management of tea plantations. We measured and analyzed soil in two organic, three ecological and one non-ecological tea gardens at depths of 0–10 cm and 10–20 cm in Anxi County. According to Duncan multiple comparisons and t tests, soil nutrients differed between organic and ecological or non-ecological tea gardens at 0–10 cm. Organic matter and total nitrogen differed between organic and non-ecological tea garden soils at 10–20 cm. In organic tea gardens, soil bulk density, porosity, relative water content, soil organic matter, total nitrogen and total phosphorus were advantageous for tea tree growth. In ecological tea gardens, the indicators were appropriate and relatively advantageous for tea tree growth at a soil depth of 0–10 cm. For non-ecological tea garden, the nutrients were at a compact level and negatively affect tea growth. These results show that soil properties and nutrient content in organic and ecological tea gardens are superior to non-ecological tea garden. The development of organic tea gardens is the most suitable strategy for the growth of tea trees.%安溪县是中国最大的铁观音主产区。“安溪铁观音茶文化系统”于2014年入选为“中国重要农业文化遗产”。安溪茶园经营方式主要分为有机茶园、生态茶园和非生态茶园三大类。本研究采用不同物理化学分析方法，对安溪县2处有机茶园、3处生态茶园和1处非生态茶园不同深度的土壤进行测定分析，比较不同类型茶园土壤性状及主要养分含量中的多项指标，为茶园合理地经营管理提供了科学依据。通过Duncan多重比较检验和t检验发现：在0-10cm土壤深度上，有机与生态、非生态茶园各土壤养分大部分指标差异性显著（P<0.05）；在10-20cm土壤深度上，有机与非生态茶园的有机质和全氮差异性显著。此外，有机茶园不同深度土壤容重、孔隙度和相对含水量以及有机质、全氮和全磷对茶树生长非常有利；生态茶园0-10cm深度土壤各指标适宜，比较有利于茶树生长；非生态茶园在不同深度土壤中的各养分都较为缺乏，不利于茶树生长。研究结果表明：有机茶园和生态茶园土壤总体肥力优于非生态茶园，有机茶园的建设模式更适宜茶树生长。
