Ammonium (NH₄⁺) would influence the uptake and translocation of Cd and Zn to mediate their interactions in wheat. Thus, the effects of NH₄⁺ on Cd and Zn uptake, translocation, subcellular distributions and Cd chemical forms in dwarf polish wheat (DPW, Triticum polonicum L.) under Cd, Zn and Cd + Zn stresses with lack or supply of NH₄⁺ was investigated. The biomasses of root and shoot were reduced by NH₄⁺. NH₄⁺ enhanced Cd and Zn uptakes, but inhibited their translocations. Under lack and supply of NH₄⁺, Zn inhibited Cd uptakes, but promoted Cd translocations. Meanwhile, NH₄⁺ reinforced the inhibition of Cd uptake and the promotion of Cd translocation caused by Zn. Cd inhibited Zn uptake and promoted Zn translocation under lack of NH₄⁺. Meanwhile, Cd slightly reduced the Zn uptake, but did not affect the translocation under supply of NH₄⁺. Therefore, NH₄⁺ alleviated the inhibition of Zn uptake and partly reduced the promotion of Zn translocation stimulated by Cd. NH₄⁺ and Zn changed the subcellular distributions and chemical forms of Cd. NH₄⁺ and Cd also influenced the subcellular distributions of Zn. The changed subcellular distributions and chemical forms were associated with Cd and Zn uptakes and translocations, which physiologically revealed and illustrated NH₄⁺ participates in Cd/Zn interactions.

铵（NH ₄ ⁺）会影响镉和锌的吸收和转运，以调节小麦中的相互作用。因此，在缺乏或供应NH _4的Cd，Zn和Cd + Zn胁迫下，NH ₄ ⁺对矮波兰小麦（DPW，Triticum polonicum L.）中Cd和Zn的吸收，转运，亚细胞分布和Cd化学形态的影响。⁺被调查。NH ₄ ⁺降低了根系和枝条的生物量。NH ₄ ⁺增强了Cd和Zn的吸收，但抑制了它们的易位。在缺乏和供应NH ₄ ^{+的情况下}，Zn抑制了Cd的吸收，但促进了Cd的易位。同时，NH₄ ⁺增强了Zn引起的Cd吸收抑制和Cd转运的促进。在缺乏NH ₄ ^+的情况下，Cd抑制了Zn的吸收，促进了Zn的转运。同时，Cd稍微降低了Zn的吸收，但不影响NH ₄ ⁺供给下的转运。因此，NH ₄ ⁺减轻了对锌吸收的抑制，并部分降低了Cd刺激的Zn转运的促进。NH ₄ ⁺和Zn改变了Cd的亚细胞分布和化学形式。NH ₄ ⁺镉也影响锌的亚细胞分布。改变的亚细胞分布和化学形式与Cd和Zn的吸收和易位有关，从生理学上揭示并说明了NH ₄ ⁺参与Cd / Zn的相互作用。
