采用盆栽试验，研究了有机肥、石灰、蛭石和白云石4种改良物质对毛叶野豌豆（Vicia villosa var.）生长和重金属（Cu、Cd、Pb和Zn）积累的影响。光萼草铅锌尾矿污染土壤中的云广藻分析了土壤pH值和有效态重金属含量的变化。结果表明：4种改良剂均显著提高了土壤pH值，降低了土壤重金属有效态含量。因此，Cd和Pb从根向地上部的运输受到限制，从而减少了重金属在地上部的积累。施用改良剂显著促进了白花葡萄的生长，提高了白花葡萄的株高、地上部鲜重、根鲜重和叶绿素含量。株高和地上部鲜重的诱导变化显著（P
A pot experiment was conducted to determine the effects of four amendment substances (organic manure, lime, vermiculite and dolomite) on the growth and heavy metal (Cu, Cd, Pb and Zn) accumulation in Vicia villosa var. glabrescens cv. Yunguangzao in soils contaminated with Pb/Zn mine tailings. Changes in soil pH and available heavy metal content induced by the amendments were also analysed. Results showed that the four amendments significantly increased soil pH, while reducing available heavy metal content in soil. Hence, the transport of Cd and Pb from the roots to the shoots of V. villosa was limited, which reduced heavy metal accumulation in the shoots. The amendments significantly improved the growth of V. villosa, while increasing plant height, shoot and root fresh weight and chlorophyll content of V. villosa. The induced changes in plant height and shoot fresh weight were significant (P
