The soil barrier factors currently present in Tuquan County, Northeast China, such as drought, waterlogging, stickiness, salt, alkalinity, and barrenness. This study chose to build a core demonstration area of 50 mu in Xinglongshan Village, Tuquan County. Seven improvement measures were adopted for soil improvement, including straw returning, alkaline amendment, desulfurization gypsum, organic fertilizer, deep tillage and deep loosening, furfural residue, and salt alkali tolerant variety screening. After adopting the above measures, the average soil pH value decreased by 0.4-0.9, the total salt content decreased by more than 10%, and the organic matter increased by more than 0.2 percentage points. The physical and chemical properties of the soil in the experimental area were significantly improved. These measures not only significantly improve the soil fertility of saline alkali farmland and increase the average grain yield by more than 15 percentage points, but also play a role in protecting farmland, thus forming a virtuous cycle.
