丹皮道地产区环境地球化学特征研究

Studies on Environmental Geochemistry in District Road Areas of Peony

对丹皮道地产区土壤地球化学特征进行了系统研究,通过丹皮产区土壤的测试分析,将其与安徽省土壤背景值比较,摸清了丹皮道地药材产区土壤的元素本底特征。结果表明,该产区多数元素明显高于全省土壤背景值,有机质、硼元素低于全省土壤背景值。丹皮的长势和品质与其地质地球化学背景有着密切的关系;母岩类型不同,土壤地球化学成分存在较大的差异;丹皮中生化成分与土壤中相应元素具有显著相关性。

Based on the geochemical characteristics of the soil, the peony in chstnct roau areas was studied. In comparison to Anhui soil background values, the content of most elements in the soil of peony producing are higher, the content of organicmatter and B are lower. The results show that the growth and quality of peony in Tongling are related to the geochemical background. Because of different rock types, chemical dements of the soils differ. There is a pronounced correlation between biochemical composition of peony and their corresponding effective content in soils.
