| 摘 要： | 采用人工控制光温条件的营养液培养方法，研究了营养液中磷营养对苗期水稻吸收不同浓度镉的影响，结果表明：（１）随着生长介质中磷营养浓度（磷的处理浓度为５，１０，１５ｍｇ／Ｌ）的增加，水稻植株的生物量和株高无明显变化；在各个磷处理水平上，随着镉浓度的增加，水稻地上部镉含量呈增加趋势；（２）随着营养介质中磷浓度的增大，Ｃｄ０．１，Ｃｄ０．５，Ｃｄ１．０处理的水稻地上部镉含量均呈增加趋势，尤其是高镉浓度处理

| Abstract: | Solution culture was conducted to investigate the effect of P on Cd uptake by riceplant. The results showed that the biomass and the height of rice with the different Cd concen-tration did not significantly increase or decrease with the increase of P concentration in nutrientsolution,but the content of Cd in the shoot of rice increased at P10, P15 treatments. Cd contentof rice shoot increased at each P treatment with the increase of Cd concentration. |
