Soil salinization is one of the major abiotic stresses affecting plant growth and development. Plant salt tolerance is controlled by complex metabolic pathways. Exploring effective methods and mechanisms to improve crop salt tolerance has been a key aspect of research on the utilization of saline soil. Exogenous substances, such as plant hormones and signal transduction substances, can regulate ion transmembrane transport and eliminate reactive oxygen species (ROS) to reduce salt stress damage by activating various metabolic processes. In this review, we summarize the mechanisms by which exogenous substances regulate ion transmembrane transport and ROS metabolism to improve plant salt tolerance. The molecular and physiological relationships among exogenous substances in maintaining the ion balance and enhancing ROS clearance are examined, and trends and research directions for the application of exogenous substances for improving plant salt tolerance are proposed.
土壤盐渍化是影响植物生长发育的主要非生物胁迫之一。植物的耐盐性受复杂代谢途径的控制。探索提高作物耐盐性的有效方法和机制一直是盐碱土利用研究的关键方面。外源物质，如植物激素和信号转导物质，可以通过激活各种代谢过程来调节离子跨膜运输并清除活性氧（ROS），从而减轻盐胁迫损伤。在本综述中，我们总结了外源物质调节离子跨膜运输和ROS代谢以提高植物耐盐性的机制。研究了外源物质在维持离子平衡和增强ROS清除方面的分子和生理关系，并提出了应用外源物质提高植物耐盐性的趋势和研究方向。
