盆栽試驗中鎘對紫花苜蓿的出苗率、根、莖的生物量的影響與種子的萌發呈現同一規律;鎘在紫花苜蓿體內的含量也與土壤中鎘濃度有關:低濃度0 ? 6mg kg時,紫花苜蓿根部的鎘含量低於莖、葉中的鎘含量,但己超出我國飼料衛生標準2倍,濃度大於10mg / kg時,根部的鎘含量比飼料衛生標準高出20倍,而土壤中鎘含量大大降低,所以此時的紫花苜蓿是修復鎘污染土壤的較好的植物;當加200mg kg鋅后,鎘的毒害作用明顯減小,隨著生長時間的增長,生物量受鎘的影響也在減小,同時紫花苜蓿體內的鎘含量大幅度降低,有些己降到飼料標準以下。The proper atomic clustcr model is developed in the papel according to calculating results of quantuin chemiwt and the theory of sanderson electro - negativity the law of electron distribuing in brass material and the electto - negativity of brass - zinc are established
