摘要：
A method of producing artificial bio-soil aggregates based on foamed concrete for plant growth that can ensure sufficient moisture and plant nutrients for the habitat of plants in non-soil conditions； obtain a lightweight, durable, and deep soil layer, and continuously provide a favorable environment for plant growth. A paste is prepared by mixing cement with an admixture, such as ochre and burnt-furnace slag； foamed concrete is formed by adding foam bubbles with an appropriate foaming rate to said paste, thereby producing soil concrete. When the foamed concrete is used, a designated compressive strength can be ensured and a number of pore spaces are formed, which allow the air to be sucked and expelled therethrough and store moisture therein. Also, hydrogel that is incorporated into the foamed concrete may supply nutrients required for plant growth, improve pest resistance, and store and supply a large amount of water.
