Description

Soil conditioner and seedling planting method adopting same

Technical Field

The application relates to the field of landscaping construction, in particular to a soil conditioner and a seedling planting method adopting the soil conditioner.

Background

The soil conditioner is also called soil conditioner, and is a material which can improve the physical property of soil and promote the nutrient absorption of crops, but does not provide plant nutrients. The soil amendment utility principle is to bind many small soil particles to form large, water-stable aggregates. The method is widely applied to the aspects of preventing soil from being corroded, reducing water evaporation or excessive transpiration of the soil, saving irrigation water and promoting healthy growth of plants.

The invention discloses a soil conditioner for landscaping and a preparation method thereof in a Chinese patent application with publication number CN112080281A, which comprises the following steps: mixing the paper mulberry powder and a phosphoric acid solution, adding disproportionated rosin, uniformly stirring, carrying out extrusion forming, activating at high temperature, washing and drying to obtain pretreated paper mulberry powder; stirring montmorillonite and polar solvent, adding zinc dicarboxylate under stirring, continuously stirring, filtering, drying, pulverizing, calcining at 200-300 deg.C for 1-2h, and pulverizing to obtain pretreated montmorillonite; adding water into pretreated paper mulberry powder, adding pretreated montmorillonite under stirring, performing ultrasonic treatment, sequentially adding acrylamide, N' -methylene bisacrylamide, foaming agent and dispersing agent under stirring, stirring to fully foam, adding initiator, and stirring uniformly to obtain a compound material; and feeding the compound material into a forming die, adjusting the temperature to 70-80 ℃, preserving heat for 1-2h, performing irradiation treatment, then performing staged temperature rise and preservation, cooling along with a furnace, and crushing to obtain the soil conditioner for landscaping.

In view of the above-mentioned related technologies, the inventor believes that when the soil matrix is applied in the urbanization process, the soil matrix is mostly artificial backfill and contains a large amount of soil invaders such as gravel, lime, asphalt, construction waste and the like, so that the soil is compacted and hardened, the oxygen concentration in the soil is reduced, the air permeability is reduced, and the plant growth is not facilitated.
