Abstract: In order to explore the soil properties of wild Bletilla striata habitat under forest, the soil of wild Bletilla striata habitat under forest was collected in Yanting hilly lands of Sichuan province, and the soil physical and chemical properties and soil enzyme activities were measured and compared with those of non-Bletilla striata habitat nearby. The results showed that the pH value of the soil in wild Bletilla striata habitat was 7.198±0.034, and the soil bulk density was 1.53±0.015 g/cm³, total nitrogen content was 0.9856±0.047 g/kg, the phosphorus content was 0.798±0.053 g/kg, the content of available phosphorus was 18.4±1.4 mg/kg, the content of hydrolysable nitrogen was 60.87±1.85 mg/kg. However, the activities of phosphatase, urease, catalase and invertase in the soil of wild Bletilla striata habitat were significantly higher than those of the control, and its roots had better ability to utilize and transform soil organic matter.
