饲料卫生标准 - When the concentration is low , 0 - 6 mg / kg , the content of cadmium in the root of alfalfa is lower than in the stern and leaf , but two times higher than the forage hugiene standard of our country . when the concentration is higher than 10mg / kg , the content of cadmium in the root is 20 times higher than the standard , but the content of cadmium in the soil decreased obviously , so alfalfa of this condition is the best alternative for renovating polluted soil . when 200mg / kg znic is added , the poison of cadmium is decreased dramatically with the grow time increasing , the cadmium effect on living number decreased
盆栽试验中镉对紫花苜蓿的出苗率、根、茎的生物量的影响与种子的萌发呈现同一规律；镉在紫花苜蓿体内的含量也与土壤中镉浓度有关：低浓度0 ? 6mg kg时，紫花苜蓿根部的镉含量低于茎、叶中的镉含量，但己超出我国饲料卫生标准2倍，浓度大于10mg / kg时，根部的镉含量比饲料卫生标准高出20倍，而土壤中镉含量大大降低，所以此时的紫花苜蓿是修复镉污染土壤的较好的植物；当加200mg kg锌后，镉的毒害作用明显减小，随着生长时间的增长，生物量受镉的影响也在减小，同时紫花苜蓿体内的镉含量大幅度降低，有些己降到饲料标准以下。
