摘　　要：研究了镉锌交互污染的土壤中,不同镉锌含量对紫花苜蓿吸收镉的量和品质的影响,研究表明:紫花苜蓿中镉含量随土壤中镉含量的增加而增加,锌抑制紫花苜蓿对镉的吸收,紫花苜蓿含镉量与土壤中有效态镉的含量呈显著线性相关。低浓度镉对紫花苜蓿蛋白质的合成有促进作用,高浓度镉对蛋白质合成有抑制作用。研究表明:在土壤受到低浓度镉污染的情况下,种植紫花苜蓿是可行的。In the contaminative soil of cadmium and zinc,the different concentration of cadmium and zinc influence alfalfa′s quality and cadmium content.The research indicate,when the concentration of cadmium increase,the content of cadmium in alfalfa increase.Zinc depress the absorption of cadmium.The cadmium concentration in soil and alfalfa is a liner response.The low concentration cadmium in soil accelerate the protein,the high concentration cadmium in soil depress the protein,The research indicate： It′s feasible to plant alfalfa in the low concentration of cadmium.
