摘　要：摘　要：钙(Ca2+) 既是植物重要的营养元素，也可作为第二信使感受到外界环境刺激，引起一系列保护性生理反应，从而减轻环境胁迫的伤害。盐胁迫严重影响植物( 农作物) 发育、生长和产量。大量研究表明，Ca2+ 对植物盐害具有抗性。现就针对盐胁迫对植物的伤害机制和Ca2+ 在盐胁迫中的功能和调控机制的研究进展进行综述。

Abstract: Abstract: Ca2+ is not only a necessary element for plants， but also as the second messenger causes a series of physiological responses in order to protect plants from environmental stress when exposed to environmental stimuli. Salt stress seriously affects plants (crops) development， growth and yield. Studies showed that Ca2+ improves plants resistance to salt stress. Some functions and regulatory mechanisms about Ca2+ involvement under salt stress were mainly discussed.
