Soil salinization is one of the current global environmental problems. Current research on crops in saline-alkali land focuses on salt tolerance, but less on its ecological benefits. However, plants and the environment can interact and influence each other, which is the theory used to carry out Nature-based Solutions (NbS). Therefore, the research on crop plants with both ecological and economic benefits is novel and valuable work. Then three widely planted cash crops (Solanum melongena, Momordica charantia, Capsicum annuum) were selected for salt stress treatment (NaCl, 150mmol/L), some physiological indicators (chlorophyll, soluble protein, Proline (Pro), malondialdehyde (MDA)) of plant and the soil properties (electrical conductivity, pH, the soil salt content) were measured. The results showed that the salinity content of the three plant cultivation soils was significantly different (P<0.05) after the salt stress; all three crops had some desalination capacity, but Capsicum annuum had the strongest salt resistance and desalination capacity.
土壤盐渍化是当前全球环境问题之一。当前，关于盐碱性土地作物的研究主要集中在耐盐性方面，而对其生态效益的关注较少。然而，植物与环境可以相互作用和影响，这就是基于自然的解决方案（NbS）所采用的理论。因此，研究兼具生态和经济效益的作物是一项新颖而有价值的工作。然后，选择了三种广泛种植的经济作物（茄子、苦瓜、辣椒）进行盐胁迫处理（NaCl，150mmol/L），测量了植物的一些生理指标（叶绿素、可溶性蛋白、脯氨酸（Pro）、丙二醛（MDA））和土壤性质（电导率、pH 值、土壤盐分含量）。结果表明，盐胁迫后三种植物栽培土壤的盐分含量有显著差异（P<0.05）；三种作物都有一定的脱盐能力，但辣椒的耐盐性和脱盐能力最强。
