This invention discloses a solid waste-based bio-composite substrate for promoting the growth of cuttings, its preparation method, and its application. Belonging to the technical field of bio-composite substrates, this invention precisely regulates the physicochemical properties of the substrate to construct an optimal rhizosphere environment. Through the compounding of three types of solid waste with acidic organic fertilizer, particles of different sizes (roller slag, pressurized hot-pressurized slag, and drum slag) form an inorganic framework. Coarse particles open up the air pores, while fine particles fill the gaps, maintaining the bulk density and total porosity within a suitable range. The hydration of steel slag releases OH... ‑ It is alkaline and neutralizes acidic organic fertilizers. Simultaneously, the humic acid in the organic fertilizer complexes soluble salt ions, delaying the release of mineral elements and stabilizing the pH at a safe range of 7.98–8.65 and controlling the conductivity within a safe range of 0.46–1.48 mS / cm. These three factors synergistically create a rhizosphere environment characterized by water-air balance, acid-base buffering, and slow ion release, achieving high-value utilization of solid waste while considering both ecological and cost-effectiveness.
