复合重金属污染影响植物的研究进展

土壤复合污染情况普遍，在复合污染条件下，土壤中各重金属之间存在加和、拮抗、协同作用，使得其较单一污染更加复杂，对植物生长的影响也存在差异性。本文综述了重金属复合污染对植物生长发育、超微结构、生理生化特征的影响，复合污染条件下，植物对重金属的吸收转运规律，复合污染对植物根际微生物的影响。对明确重金属对植物生长的影响机理、提高植物对重金属的适应性具有重要的参考意义，并能够为在重金属复合污染土壤植物栽培及育种奠定理论基础。

Advances in research on the effects of complex heavy metal pollution on plants

Soil complex pollution is common, there are additive, antagonistic, and synergistic effects between the different heavy metals in the soil under complex pollution conditions, making it more complex than single pollution and having different effects on plant development. This paper reviews the effects of heavy metal complex pollution on plant growth and development, physiological, ultrastructure and biochemical characteristics, the uptake and transport patterns of heavy metals by plants and the differences in plant inter-root microorganisms under complex pollution conditions. It is of great significance to clarify the mechanism of heavy metal effects on plant growth and improve the adaptability of plants to heavy metals, and can lay the theoretical foundation for plant cultivation and breeding in heavy metal-contaminated soils.
