The invention has the following beneficial effects:
1. the method for preparing the nutrient soil by using the residue soil and the slurry adopts a method for preparing the nutrient soil matrix by pretreating the residue soil and the slurry, and other components can be freely matched according to actual planting requirements on the basis of the matrix, so that the nutrient soil suitable for different plant types is prepared.
2. The mud in the invention is made into a sphere, so that the transportation is more convenient for users; when the powder needs to be reconfigured for use, the powder can be moderately crushed according to the use requirement.
3. For the vegetation, the substrate can be directly used for planting after being matched with garden soil in a certain proportion, and special materials do not need to be added, so that the vegetation growing medium is practical and convenient.
4. The nutrient soil matrix also adopts eggshells of a hatchery as raw materials, and the eggshells contain rich calcium and trace elements such as zinc, copper, manganese, iron, selenium and the like, and can provide nutrient elements required by plant growth for the nutrient soil. Meanwhile, the garbage in the hatchery is also treated, and the garbage is recycled.
