The present invention provides the following technical solution: a method for preparing a cultivation-specific foamed substrate material, including the following steps: 1) preparation of a resin produced from biomass liquefaction: A. preparation of the following raw materials, in parts by weight: 100 parts of raw biomass material, 30 to 90 parts of composite liquefacient, 15 to 25 parts of liquefaction catalyst, 20 to 40 parts of alkaline catalyst, and 40 to 80 parts of formaldehyde; B. heating a reactor to 60°C, adding the composite liquefacient, raw biomass material and liquefaction catalyst, and stirring at a constant speed; heating to 120°C to 130°C and conducting reaction at this temperature for 10 min to 30 min; stopping the reaction and cooling to 60°C; adding the alkaline catalyst to adjust the PH to alkaline; adding formaldehyde, heating to 85°C to 95°C, and conducting reaction at this temperature for 20 min to 30 min; and stopping the reaction, and cooling to 60°C to obtain a resin produced from biomass liquefaction; and 2) preparation of a cultivation-specific foamed substrate material. The substrate material obtained by this method is environmentally friendly.
