Biochar is a promising solution to alleviate the negative impacts of salinity stress on agricultural production. Biochar derived from food waste effect was investigated on three plant species, Medicago sativa, Amaranthus caudatus, and Zea mays, under saline environments. The results showed that biochar improved significantly the height by 30%, fresh weight of shoot by 35% and root by 45% of all three species compared to control (saline soil without biochar adding), as well as enhanced their photosynthetic pigments and enzyme activities in soil. This positive effect varied significantly between the 3 plants highlighting the importance of the plant-biochar interactions. Thus, the application of biochar is a promising solution to enhance the growth, root morphology, and physiological characteristics of plants under salt-induced stress.
生物炭是缓解盐胁迫对农业生产负面影响的一种很有前景的解决方案。研究了在盐环境下，由食物废料制成的生物炭对三种植物（紫花苜蓿、尾穗苋和玉米）的影响。结果表明，与对照（不添加生物炭的盐渍土壤）相比，生物炭显著提高了所有三种植物的株高30%、地上部鲜重35%和根部鲜重45%，同时还增强了土壤中的光合色素和酶活性。这种积极作用在这三种植物之间有显著差异，突出了植物与生物炭相互作用的重要性。因此，生物炭的应用是增强盐胁迫下植物生长、根系形态和生理特性的一种很有前景的解决方案。
