| 摘 要： | 采用麦饭石、石灰、紫云英和过磷酸钙等几种改良剂及通电处理改良铅污染菜园土壤的结果表明：小白菜吸收的铅主要来自土壤中的交换态铅；用小白菜含铅量和土壤中交换态铅降低的幅度来评价改良剂的改良效果结果是一样的，其顺序为石灰、紫云英、麦饭石和过磷酸钙；通电处理可以显著地降低交换态铅含量，其改良效果优于所用的４种改良剂．

| Abstract: | Lime, green manure(Astragalus sinicus),Maifanshi and lime superphospateas soil amendment and electric field treatment were utilized to improve lead-polluted soils.The results indicated that Pb in cabbage(Brassica Chinensis L.Var),which mainly camefrom exchangeable fraction of the Pb in soil,was decreased significantly by the amendment.The effect of the amendment showed the same tendency evaluated by either the Pb content ofcabbage or the decreasing range of the exchangeable-pb in soil in the order of Lime>greenmanure>Maifanshi>Lime superphospate.The second crop of cabbage had proved that theameliorators were still effective.The exchangeable-Pb in soil which had been treated byelectric field decreased significantly.This effect was related to voltage gradient used andtime.In some way,the effect of electricity treatment was better than that of the amendmentused in this experiment. |
