摘　　要：以赤子爱胜蚓、太平二号蚓为试验对象,分别对其展开锌离子的急性毒性试验、耐受限度试验和富集效应试验,探究利用蚯蚓对污染土壤进行联合修复的可能性。结果表明,赤子爱胜蚓的LC50值在800~1200mg/kg,太平二号蚓的LC50值在400~800mg/kg;赤子爱胜蚓体重受Zn^2+限制的程度低于太平二号蚓;赤子爱胜蚓及太平二号蚓对土壤中均具有一定的富集能力,赤子爱胜蚓对土壤中锌离子的富集量更大。In this study,we conducted the acute toxicity experiment,tolerance limit experiment and enrichment effect experiment of zinc ions on Chizi Aisheng Earthworm and Taiping No.2 Earthworm,aiming to explore the possibility of using earthworms to carry out joint remediation of contaminated soil,which provides theoretical support for the domestication of earthworms and breed selection.The experimental results show that the LC50 value of Chizi Aisheng worm is between 800-1200 mg/kg,and the LC50 value of Taiping No.2 worm is 400-800 mg/kg;Earthworms;Chizi Aisheng Earthworm and Taiping No.2 Earthworm have a certain enrichment capacity in the soil,and Chizi Aisheng Earthworm has a greater concentration of zinc ions in the soil.
