| 摘 要： | 以当前农业研究的热点领域——重金属污染为切入点,研究了大田Cd、Pb、As、Hg、Cr5种重金属胁迫对小麦(郑麦9023、小偃22)籽粒产量及构成因素的影响。结果表明重金属胁迫下,Cd、Pb、As、Hg、Cr重金属对产量三要素中单位面积群体穗数的影响最大,其次为穗粒数,对千粒重的影响最小;单位面积群体穗数对重金属Cr、Pb最为敏感,在旱田偏碱性的土壤上,Cr、Pb胁迫对小麦单位面积的群体穗数影响的临界含量分别约为187.5mg.kg-1和175mg.kg-1。对两个小麦品种的籽粒产量影响不同,郑麦9023籽粒产量依次为Cr2

| Abstract: | In this article,effects of 5 heavy metals(Cd,Pb,As,Hg,Cr) stress on wheat(Zhengmai9023,Xiaoyan22) yields and ingredient in farmlands were analyzed.The results showed that 5 heavy metals greatly influenced on spikes per hectare,then followed kernels per spikes and weight of 1 000 kernels;and spikes per hectare was sensitive to Cr and Pb,which the critical values of Cr and Pb to spikes per hectare were 187.5 mg·kg-1,175 mg·kg-1,respectively,in glebe and alkaline soils.Furthermore,the grain yields of two wheat genotypes were also affected by Cd,Pb,As,Hg,and Cr compared with CK treatment;and the grain yield order of Zhengmai9023,Xiaoyan22 under 5 heavy metals stress were Cr2
