摘　　要：研究结果表明：土壤含铜量过高，对紫云英造成危害；受铜害最明显的症状出现在根部，根部受害后，主根伸长受阻，分出短粗叉根；根结构受到破坏后，表皮层断裂，皮层、中柱细胞逐渐解体死亡。The research results show that too high copper content in the soil will do damage to Milk Vetch. The most appearent symptoms are in its root.Being damaged the extension of the main root is hindered, and short and thick branches from the main root grow. When the root structure is damaged, the epidermis breaks,the cortex and central cells disintegrate and die gradually.
