| 摘 要： | 含有不同铅离子浓度的土壤在种植冰草后,土壤p H和水溶性盐含量都明显下降,说明冰草吸收土壤中的盐分,可降低土壤的盐碱度,而且土壤中的重金属含量都有所降低,特别是Pb2+含量降低了99%以上,说明冰草可以用来改良修复铅污染的土壤。

Research on Remediation Technology of Wheatgrass for Lead Contaminated Soil |
| |
| Abstract: | The pH and water soluble salts content of soil with different concentrations of lead ions were decreased obviously after planting wheatgrass.It indicated that wheatgrass absorbed the salt content of soil,reduced soil salinity.The content of heavy metals in soil was decreased,especially lead ions in soil was decreased more than 99％.It was referred that wheatgrsss could be used to improve the remediation of lead contaminated soil. |
