摘　　要：随着环境恶化,盐胁迫日益成为一个全球问题。盐胁迫影响植物的水分运输和光合作用过程,导致植株生长缓慢甚至死亡。植物在盐胁迫下水分运输效率降低,造成光合作用原料之一水供应不足,引起光合作用受抑制。光合作用受抑制导致植物碳同化量积累不够不足以维持植物生长,从而影响植物的生长和发育。总结盐胁迫对植物的水分状况和光合作用的影响及作用机制,为探究植物在盐胁迫下的适应机制提供参考,对植物在盐滞化土壤中更好地生长发育提供理论基础。With the deterioration of the environment, salt stress is becoming a global problem. Salt stress affects water transport and photosynthesis of plants and causes slow growth and even death of plants. Under salt stress, water transport efficiency of plants is reduced, resulting in insufficient water supply as one of the raw materials for photosynthesis, resulting in inhibition of photosyn-thesis. Inhibited photosynthesis leads to insufficient accumulation of carbon assimilation in plants, which is insufficient to maintain plant growth, thus affecting plant growth and development. In this paper, the effects of salt stress on water status and photosynthesis of plants and their mechanisms of action were summarized to provide reference for exploring the adaptation mechanism of plants under salt stress, and to provide a theoretical basis for better growth and development of plants in salt-retarded soil.
