摘要
通过对 Cd,Cr,Pb3种重金属元素对土壤脲酶活性的抑制性进行试验 ,分析不同重金属用量、培养时间、单因素以及复合因素条件下对脲酶活性的影响。结果表明 :3种重金属在不同情况下对脲酶活性均有不同程度的抑制作用 ,也证明了在一定的农业环境条件下 。
The results of comparing Cd Cr and Pb single element with compound pollution in the experiment show that the inhibiting effects of Cd, Cr and Pb single element as well as their compound pollution on soil urease have a toxicity order of Cr>Cd>Pb. They also show that 3 kinds of heavy metals activity under different conditions have different level inhibition to urease. At the same time, they have also proved under certain agricultural ambient conditions, that the material of heavy metal can produce certain influence and damage to agricultural ecological environment.
