Abstract

Soil salinization is a significant threat to soil health, especially to the agricultural ecosystem; it reduces vegetation biomass, destroys ecosystem diversity, and limits land use efficiency. This area of investigation has garnered extensive attention in China, especially in the arid and semi-arid areas, totaling 7.66 × 106 ha. A variety of theoretical research and technology developments have contributed to soil water and salt regulation and the screening of salt-tolerant varieties to improve nutrient utilization efficiency and microbial control and reduce ecological problems due to saline-based obstacles. These techniques can be classified into physical treatments, chemical treatments, biological treatments, and combined treatments; these different measures are all aimed at primarily solving saline–alkali stress. In general, the improvement and utilization of saline–alkali soil contribute to soil health improvement, concentrating on high-quality development, food security, ecological security, cultivated land protection, and agricultural upgrading. However, the risks of various technologies in the practical production process should be highlighted; green and healthy measures are still expected to be applied to saline–alkali land.

盐碱地改良有助于改善中国的土壤健康状况

土壤盐碱化是对土壤健康，尤其是农业生态系统的重大威胁；它降低了植被生物量，破坏了生态系统的多样性，限制了土地的利用效率。这一研究领域在中国受到广泛关注，尤其是在干旱和半干旱地区，总面积达 7.66 × 106 公顷。各种理论研究和技术发展促进了土壤水盐调控和耐盐品种筛选，以提高养分利用效率和微生物调控能力，减少盐碱障碍带来的生态问题。这些技术可分为物理处理、化学处理、生物处理和综合处理；这些不同的措施都是以解决盐碱胁迫为主要目的。总体而言，盐碱地改良与利用有助于改善土壤健康状况，集中体现在高质量发展、粮食安全、生态安全、耕地保护和农业升级等方面。但在实际生产过程中，各种技术的风险也应引起重视，绿色健康的措施仍有望应用于盐碱地。
