An ion-exchange microbial carrier and a saline-alkali land improvement technology are characterized in that they are composed of oyster shell powder, flue gas desulfurization gypsum, vinegar grains, sulfur, and sodium thiosulfate. The innovation of the invention lies in that it can adsorb sodium ions and control the harm of salt; reduce the pH value and promote the utilization of soil nutrients; change the soil structure, increase the permeability and increase the biological activity; increase the soil carbon content and improve the soil organic matter. Various components work synergistically and cooperate with each other, which is more suitable for various saline-alkali soils, especially for alkaline soils in areas lacking fresh water. |
