The invention discloses a straw biochar-based soil phosphorus active conditioner and a preparation method thereof, and belongs to the technical field of agriculture. The straw biochar-based soil phosphorus active conditioner comprises, in parts by weight, acid-modified straw biochar 40-60 parts, an chelating agent 10-15 parts, a phosphorus-releasing bacteria agent 5-10 parts, an acidifying agent 10-15 parts and a filler 5-10 parts. The conditioner controls the adsorption-desorption performance of straw biochar on phosphorus at an appropriate level to meet the demand of crops for phosphorus, balances the fixation and activation of soil phosphorus, and prevents the risk of phosphorus leaching and releasing while meeting the needs of crops, and has good economic, environmental and ecologicalbenefits.
