Deep plowing improvement: Carry out deep plowing of 30-40 cm on the saline-alkali land. The soil should be as fine as possible, and this should be done multiple times vertically and horizontally. Biological improvement: You can plant some salt-tolerant plants in the land, such as rose, wolfberry, white wax, etc. Soaking field improvement: Establish a good irrigation and drainage system. After irrigation, soak and dry. If there is salt crystallization, soak again.

1. Deep cultivation and improvement

1. Deep plowing and improvement

This is a very simple method. The saline-alkali land that needs to be improved is plowed deeply, about 30-40 centimeters deep. The requirement is that there are no large clods of soil in the land and the soil is as fine as possible. When deep plowing should be carried out as many times as possible vertically and horizontally, the depth of deep plowing and the fineness of the soil should be satisfied.

2. Biological improvement

Yes Plant some salt-tolerant plants in saline-alkali land, such as rose, wolfberry, white wax, etc. When planting, you can apply some bacterial fertilizer, which can greatly improve the fertility of the land and reduce the evaporation of water, which can also achieve good results.

3. Soaking field improvement

A system should be established to separate irrigation and drainage, and the water level underneath should be well controlled. Irrigate the soil with water, soak it for about two days and then drain it. Repeat this two or three times and then dry it. At this time, check whether there are salt crystals in the soil. If so, you should continue soaking in water.
