摘要: 以不添加重金属的土壤为对照(CK),5种重金属分别以2种梯度添加量1(Cd1、Pb1、Cr1、Hg1、As1);2(Cd2、Pb2、Cr2、Hg2、As2)添加到土壤中,研究在大田条件下经过小麦1季或小麦-玉米-小麦3季作物种植后,重金属胁迫后效对玉米产量的影响。结果表明,5种重金属处理的玉米穗轴质量、生物产量与CK持平或高于CK,其中Hg2、Cd2、Hg1、As2处理玉米穗轴质量显著高于CK;玉米穗轴质量、单穗籽粒质量、经济系数在同一重金属不同质量浓度间均表现为:高质量浓度>低质量浓度;经过小麦1季种植后,重金属(Cr1除外)处理玉米籽粒产量高于CK,其中Cd1、Pb1、Hg1处理玉米籽粒产量较高,分别达到了8 276.7,8 059.9,7 879.5 kg/hm2,而且Cd1、Pb1处理显著高于CK(6 675.5 kg/hm2)。

Abstract: In this article,five heavy metals were added into the soil with gradient addition amount(Cd1,Pb1,Cr1,Hg1,As1; Cd2,Pb2,Cr2, Hg2, As2),and the later effects of five heavy metals (Cd, Pb, As, Hg, Cr) stress onmaize grain yields after wheat planted one season and wheat- maize- wheat planted three seasons,were analyzed.Theresults showed that weight of corncobs and biomass under five heavy mentals stress treatments were not lower than that of CK treatment; and weight of corncobs under Hg2,Cd2,Hg1,As2 treatments were significantly higher than that of CK treatment.For the same heavy metal,weight of axis, weight of grain yield per plant, economical coefficient values were all higher in higher dose than lower dose After wheat planted one season, maize grain yields under heavy mental stress treatments (except Cr1 treatment) were higher compared with that under CK treatment,maize grain yields were higher under Cd1 (8 276. 7 kg /ha),Pb1 (8 059. 9 kg /ha),and Hg1 (7 879. 5 kg /ha) treatments,especially under Cd1,Pb1 stress,significantly higher than CK (6 675. 5 kg /ha) treatment.
