This is a very simple method, which requires deep cultivation of the salt and alkali land to be improved, about 30-40 cm. The requirement is that there is no large soil mass in the land, and the soil should be as thin as possible. Deep ploughing should be carried out as many times as possible vertically and horizontally, and the depth of deep ploughing and the fineness of soil should meet
You can plant some salt tolerant plants in the saline alkali land, such as rose, wolfberry, Baila, etc. When planting, you can apply some bacterial fertilizer, which can improve the fertility of the land, so as to reduce the evaporation of water, which can also play a good effect
We should establish a system that can separate irrigation and drainage, and control the water level well. Water the soil, soak it for about two days, then drain it, repeat it for two or three times, and then dry it. At this time, check if there is salt crystal in the soil. If there is, continue to soak it in water.
