摘　　要：研究了凹凸棒石(PAL)与LC-S01不同配比材料对土壤重金属钝化和降低作物吸收量的影响。结果表明,施PAL 4500.0 kg/hm^2时能有效提高苦荞产量,比对照增加20.4%。施LC-S011500.0 kg/hm^2+凹凸棒石3000.0 kg/hm^2时,苦荞根、茎、籽粒对重金属的吸收量不同程度地降低,籽粒中Cu、Zn、Cd和Pb的吸收量分别降低了23.5%、23.3%、43.9%和61.0%,具有修复重金属污染的积极作用。The effects of different ratio of attapulgite(PAL)and LC-S01 on soil heavy metal passivation and reduce crop absorption were studied.The results showed that PAL could effectively increase the yield of Tartary buckwheat at 4500.0 kg/hm^2,which was 20.4%more than the control.When lC-SO1 was applied with 1500.0 kg/hm^2+attapulgite 3000.0 kg/hm^2,the uptake of heavy metals in Tartary buckwheat roots,stems and grains decreased to different degrees,and the uptake of Cu,Zn,Cd and Pb in grains decreased by 23.5%,23.3%,43.9%and 61.0%,respectively,which had a positive effect on remediation of heavy metal pollution.
