摘要
为考察被重金属污染的土壤施用土壤调理剂后对农作物产量和地上部重金属累积的影响,选用5种土壤调理剂产品(C1~C5),以生菜为对象,不施土壤调理剂的为对照(CK)处理,开展了田间小区试验。结果表明:C5、C4、C2处理可提高生菜的产量,与CK处理相比,增产率分别为9.78%、6.64%、6.85%;C5处理能有效抑制生菜对Cd、Cr、Pb、As等重金属元素的吸收,C2、C4的效果次之,C1、C3的效果不理想;与CK处理相比,C5处理的生菜地上部Cd、Cr、Pb、As含量分别降低了19.77%、27.64%、11.41%、20.62%。
In order to investigate the effect of soil conditioner application on crop yield and aboveground heavy metal accumulation in heavy metal contaminated soil,five soil conditioner products(C1-C5)are selected,with lettuce as the object and no soil conditioner as the control(CK)treatment,a field plot experiment is conducted.The results show that C5,C4 and C2 treatments can increase the yield of lettuce,compared with CK treatment,the yield increase rates are 9.78%,6.64%and 6.85%,respectively.C5 treatment can effectively inhibit the absorption of heavy metal elements such as Cd,Cr,Pb,As in lettuce,followed by C2 and C4 treatment,and the effect of C1 and C3 treatment is not ideal.Compared with CK treatment,the Cd,Cr,Pb and As contents in the aboveground parts of lettuce treated with C5 decreased by 19.77%,27.64%,11.41%,and 20.62%,respectively.
