摘要
以凤仙花为试材,采用不同浓度的铅和锌混合溶液对凤仙花幼苗进行浇灌处理,测量其株高、茎叶重、根系重、根系活力等各项指标,研究了凤仙花对重金属铅和锌的抗性。结果表明:株高、茎叶重、根系重、根系活力均随着铅、锌混合溶液浓度的增加,呈现先增加后下降的趋势,在高浓度下显著抑制凤仙花的生长,但并未失活。因此,在较高浓度重金属的土壤中,凤仙花能够生长。
With Impatiens balsamina as materials,the different concentration of lead and zinc mixture of water were treated to seedlings of Impatiens balsamina,the plant height,leaf weight,root weight and root vigor index of Impatiens seedlings were measured.The results showed that with the increase of mixture concentration,the plant height,leaf weight,root weight and root vigor increased at first and then declined,under high concentration the growth of Impatiens was inhibited,but Impatiens was not deactivated.Therefore,in the soil with high concentration metal,Impatiens could grow normally.
