Its basic measures include the following: 1. Soil chemical improvement: such as applying chemical fertilizers and various soil conditioners to increase soil fertility, improve soil structure, and eliminate soil pollution; 2. Soil water conservancy improvement: such as establishing farmland irrigation and drainage projects, regulating the groundwater level, improving soil moisture conditions, and eliminating and preventing waterlogging and salinization; 3. Soil engineering improvement: such as using engineering measures such as land leveling, building terraced fields, and diverting floods and silting to improve soil conditions; 4. Soil biological improvement: using various biological approaches (such as growing green manure) to increase soil organic matter to improve soil fertility, or building shelter forests to prevent soil erosion, etc.; 5.
