Preparation method and application of regenerated soil

The invention discloses a preparation method and application of regenerated soil, and the preparation method comprises the following steps: grinding or grinding waste concrete so that the powder diameter of regenerated concrete powder obtained by grinding or grinding the waste concrete is in a micron order, then putting the regenerated concrete powder into a carbonization chamber, and carrying out carbonization treatment on the regenerated concrete powder; the preparation method comprises the following steps: adjusting carbonization parameters (temperature, humidity, carbon dioxide content and carbonization chamber pressure), reacting at a certain carbon age to generate carbonized recycled concrete powder, preparing certain water and sand from the carbonized recycled concrete powder to form a semi-solid state, and forming under proper temperature and humidity conditions. The regenerated soil has fertility suitable for plant growth, plants grow vigorously and grow well under cultivation of the soil, and the re
