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.展开更多
