Soil salinization is a serious concern across the globe that is negatively affecting crop productivity. Recently, biochar received attention for mitigating the adverse impacts of salinity. Salinity stress induces osmotic, ionic, and oxidative damages that disturb physiological and biochemical functioning and nutrient and water uptake, leading to a reduction in plant growth and development. Biochar maintains the plant function by increasing nutrient and water uptake and reducing electrolyte leakage and lipid peroxidation. Biochar also protects the photosynthetic apparatus and improves antioxidant activity, gene expression, and synthesis of protein osmolytes and hormones that counter the toxic effect of salinity. Additionally, biochar also improves soil organic matter, microbial and enzymatic activities, and nutrient and water uptake and reduces the accumulation of toxic ions (Na and Cl), mitigating the toxic effects of salinity on plants. Thus, it is interesting to understand the role of biochar against salinity, and in the present Review we have discussed the various mechanisms through which biochar can mitigate the adverse impacts of salinity. We have also identified the various research gaps that must be addressed in future study programs. Thus, we believe that this work will provide new suggestions on the use of biochar to mitigate salinity stress.
土壤盐渍化是全球范围内一个严重的问题，正在对作物生产力产生负面影响。最近，生物炭因减轻盐害的不利影响而受到关注。盐胁迫会引发渗透、离子和氧化损伤，扰乱生理和生化功能以及养分和水分吸收，导致植物生长发育受阻。生物炭通过增加养分和水分吸收以及减少电解质渗漏和脂质过氧化来维持植物功能。生物炭还能保护光合器官，提高抗氧化活性、基因表达以及蛋白质渗透剂和激素的合成，从而对抗盐胁迫的毒性作用。此外，生物炭还能改善土壤有机质、微生物和酶活性以及养分和水分吸收，并减少有毒离子（钠和氯）的积累，减轻盐胁迫对植物的毒性影响。因此，了解生物炭对盐胁迫的作用很有意义，在本综述中，我们讨论了生物炭减轻盐害不利影响的各种机制。我们还确定了未来研究计划中必须解决的各种研究空白。因此，我们相信这项工作将为利用生物炭减轻盐胁迫提供新的建议。
