摘要： 为探求川芎中镉含量与栽培土壤pH及镉存在形态的相关性，用原子吸收法测定栽培土壤中各形态镉及对应药材中镉含量，并测定土壤pH。川芎镉含量与土壤pH相关分析结果为：r=-0.693**，P=0.001 (P＜0.01)；川芎镉含量与离子态镉含量百分比的相关分析结果为：r=0.860**，P=0.000 (P＜0.01)；土壤pH与离子态镉含量百分比的相关性结果为：r=-0.746**，P=0.003 (P＜0.01)。川芎镉含量与土壤pH成极显著的负相关关系，与土壤离子态镉含量百分比成极显著正相关；土壤pH与土壤离子态镉含量百分比成极显著的负相关关系。

Abstract: To search the correlation between the pH value of cultivated soil, the different forms of Cd content in cultivated soil and the Cd content in Ligusticum chuanxiong Hort., a field cultivation was conducted to determinate the different forms of Cd content in cultivated soil and the Cd content in corresponding Rhizoma Chuanxiong by absorption method, and measure the pH value of cultivated soil. The correlation result between the pH value of cultivated soil and the Cd content in Rhizoma Chuanxiong was r=-0.693**, P=0.001 (P＜0.01); the correlation result between the content percentage of ion-state Cd in cultivated soil and the Cd content in Rhizoma Chuanxiong was r=0.860**, P=0.000 (P＜0.01). The correlation result between the pH value and content percentage of ion-state Cd in cultivated soil was r=-0.746**, P=0.003 (P＜0.01). The Cd content in Rhizoma Chuanxiong was significantly negatively correlated to the pH values of cultivated soil, and significantly positively correlated to the content percentages of ion-state Cd in cultivated soil; the pH values and content percentages of ion-state Cd in cultivated soil was significantly negatively correlated.
