摘　　要：工业化迅速发展直接导致土壤重金属污染日益严重、土壤肥力下降、农作物产量与品质低下、重金属含量升高,经食物链传递后对人类健康和自然生态系统造成巨大威胁,因此,土壤重金属污染的修复十分重要。耐受重金属污染的根瘤菌接种豆科植物形成的共生体系能够有效缓解植物对重金属的响应,降低植物体内重金属富集量,为重金属污染土壤中种植豆科植物提供重要参考。Increasingly serious soil heavy metal pollution,decreased soil fertility,lower crop yield and quality,and increased heavy metal content are directly caused by rapid development of industrialization,which poses a great threat to human health and the natural ecosystem through the food chain transmission.Therefore,it is very important for the remediation of soil heavy metal pollution.The symbiotic system formed by legume plants inocu⁃lated with heavy metal-tolerant rhizobia can alleviate the response of plants to heavy metals and reduce the con⁃centration of heavy metals in plants by the effective strategies,which provides an important reference for legume planting in heavy metal-contaminated soil.
