摘要: 在湖北省恩施市新塘乡双河地区选取酸性富硒地块土壤,施用不同土壤调理剂,分别为过磷酸钙、石灰、硼锌钙镁肥、生物有机肥,研究对大黄、藁本、白附子、牛膝土壤pH、土壤总硒与有效硒相关性、土壤总镉与有效镉相关性以及对硒镉富集系数的影响。结果表明,调理剂石灰和生物有机肥对不同中药材土壤pH、总硒含量影响最大。不同调理剂对不同中药材土壤总硒与有效硒的相关性以及土壤总镉与有效镉的相关性并未成一致的趋势。不同调理剂处理,白附子硒富集系数显著地高于其他中药材,牛膝镉富集系数显著地高于其他中药材,而对其他中药材之间没有明显的规律。

Abstract: In the Shuanghe area of Xintang Township, Enshi City, Hubei Province, the acidic selenium-rich plot soil was selected and different soil conditioners were applied, including superphosphate, lime, boron-zinc-calcium-magnesium fertilizer and bio-organic fertilizer. The soil pH of Dahuang(Rheum palmatum), Gaoben(Ligusticum sinense), Baifuzi(Typhoniumgiganteum), Niuxi(Achyranthes bidentata), the correlation between total soil selenium and available selenium, the correlation between total soil cadmium and available cadmium, and their influence on the enrichment coefficient of selenium and cadmium. The results showed that the conditioner lime and bio-organic fertilizer had the greatest impact on soil pH and total sele nium content of different Chinese medicinal materials. Different conditioners do not have a consistent trend in the correlation between total selenium and available selenium in soil and the correlation between total cadmium and available cadmium in soil with different Chinese medicinal materials. The selenium enrichment coefficient of different conditioning agents for Baifuzi was significantly higher than other Chinese medicinal materials, and the cadmium enrichment coefficient for Niuxi was significantly higher than other Chinese medicinal materials, but there was no obvious rule among other Chinese medicinal materials.

Key words: conditioning agent, traditional Chinese medicine, soil pH, selenium, cadmium, enrichment coefficienr
