The invention provides a method for preparing fulvic acid in peat. The invention relates to a method for preparing fulvic acid in fulvic acid. The method comprises the following steps of: (1) Peat as raw material, through the dilute alkaline solution extraction, cationic surfactant as a precipitant purification, resin adsorption of metal ions for purification. The preparation process comprises four steps: (1) extracting peat with a dilute alkali solution, adding a sulfuric acid solution into the extract solution, precipitating the precipitate by acid precipitation, and collecting the filtrate to obtain a fulvic acid-containing extract solution; (2)
