摘　　要：通过盆栽试验研究了不同有机物料与不同浓度外源锌对油菜(Brassica campestris L.ssp.Chinensis L.)生长和锌含量分布的影响。结果表明,油菜生长随着外源锌浓度增加而降低,草坪草和玉米秸秆可有效缓解高浓度锌对油菜的毒害作用,猪粪、牛粪和鸡粪高浓度锌仍对油菜产生毒害作用,泥炭和风化煤高浓度锌的毒害作用表现最强。不同供试有机物料均不同程度增加了油菜地上部和地下部锌含量的比值,表明供试有机物料均促进了油菜对锌的吸收和积累。A pot experiment was conducted to study the effects of different organic materials and exogenous zinc concen-trations on the growth and zinc contents in rape. The results showed that the growth of rape plant decreased as the con-centration of zinc increased. Maize straw and lawn grass both effectively relieved the toxic effect of high concentration of zinc to rape. High concentration of zinc showed poisoning effect in the treatments of manures from pig, chicken and cattle. The strongest poisoning effect was found in the treatments of peat and weathered coal. The experimental organ- ic materials all increased the ratio of Zn in shoot to root of rape. It means that all experimental organic materials accel-erated the accumulation of Zn in rape shoot.
