[0002] Soil salinization is a global ecological problem. China's saline-alkali land affects 17 provinces and regions, primarily in Northeast China, North China, and Northwest China. With the continuous increase in population and the growing demand for resources, research on saline-alkali land improvement technologies is growing.

[0003] Regarding the improvement of saline-alkali land, the Saline-alkali Land Improvement and Utilization Laboratory has proposed a "land-adapted crop" solution based on the innovative ideas of "soil improvement to control salt, soil fertility improvement, technology integration, and application innovation." However, directly improving saline-alkali land on a large scale will result in extremely high losses of manpower, financial resources, and other resources, and some improvement methods are not ideal. Many factors affect the improvement of saline-alkali land, such as the amount of straw buried, the amount of soil deep plowing, and the amount of drainage. However, the amount of straw buried, the amount of soil deep plowing, and the amount of drainage required for the optimal improvement plan vary for different saline-alkali lands. If improvements are carried out directly on saline-alkali land, the cost is high and there is no guarantee of significant improvement results. In response to this, a simulation test method and device for saline-alkali land improvement are proposed. Utility Model Content
