| Abstract: | Anxi is the largest producing area of Tie Guanyin tea in China. "The cultural system of Tie Guanyin tea in Anxi" was selected as "Nationally 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 scientific 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 nonecological 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. |
