The invention discloses an agricultural biological wetting agent for a culture medium and a preparation method and application thereof.Polyethylene glycol and traditional Chinese medicine residue powder are blended, the polyethylene glycol is attached to the surface of the traditional Chinese medicine residue powder, in the pyrolysis carbonization treatment process, the polyethylene glycol is heated to be decomposed, an uneven structure is formed on the surface of biochar, and therefore the biochar content is increased; the specific surface area of the biochar is increased, so that the water absorption performance of the biochar is improved; then the fulvic acid and the cross-linking agent are adsorbed by utilizing the adsorption effect of the porous biochar, the fulvic acid is cross-linked among the porous structures of the biochar to form a gel structure, and the fulvic acid has excellent water absorption capacity, so that the water absorption swelling performance of the biochar is improved; then the modifi
