摘要(Abstract):

为探究林下野生白及生境土壤性质,采集了四川盐亭丘陵地林下野生白及生境土壤,并以附近非白及生境土壤为对照,测定了土壤理化性质和土壤酶活性,并进行了对比分析。结果表明,野生白及生境土壤的pH值为7.198±0.034,土壤容重为1.53±0.015 g/cm~3,全氮含量为0.9856±0.047 g/kg,磷含量为0.798±0.053 g/kg,速效磷的含量为18.4±1.4 mg/kg,水解性氮的含量为60.87±1.85 mg/kg。但野生白及生境土壤的磷酸酶、脲酶、过氧化氢酶和转化酶酶活性显著高于对照,其根部利用和转化土壤有机质的能力较好。
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 p H 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/cm~3, 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.
