摘　　要：Dunuo 201, a new sorghum combination, was planted in heavy metal contaminated areas to explore the feasibility of sorghum for soil heavy metals remediation in southern China. Its yield and heavy metal contents in stems, leaves and grains were analyzed. The results showed that Dunuo 201 could accumulate heavy metals especially in stems and leaves without significant effects on its yield. The cadmium content in grains and brewed liquor of Dunuo 201 was lower than the national standard. Therefore, Dunuo 201 can be used in planting structure adjustment in heavy metal contaminated areas in southern China, which has positive significance for the rapid remediation of heavy metal contaminated soil and the improvement of farmers’ economic benefits.为了探索高粱对土壤重金属修复可行性和有效方法,在南方重金属污染区小面积种植高粱新组合都糯201,分析了高粱产量及茎、叶、籽粒中重金属含量。结果表明:都糯201(尤其是茎叶)能富集土壤中重金属,对其产量没有显著影响,籽粒及酿造的酒镉含量低于国家标准。因此,都糯201可以作为南方重金属污染区农业结构调整的推广品种,对快速修复重金属污染土壤及提高农民的经济效益具有积极意义。
