The present disclosure belongs to the technical field of value-added urea preparation, and specifically relates to a two-component foam inhibitor and a preparation method thereof, and a method for reducing foaming in production of urea humate. In the present disclosure, a foam control agent in the two-component foam inhibitor lowers a pH value of a humate solution to reduce the production of ammonia in a urea melt, and can avoid condensation of the humate solution caused by lowering the pH value and a difficulty in adding the humate solution to the urea melt. A suspension adsorbent in the two-component foam inhibitor can adsorb free ammonia in the urea melt and ammonia generated after adding the humate solution. In summary, the two-component foam inhibitor can effectively reduce a foaming reaction during production of the urea humate, avoid powdering of urea humate particles, and improve a production efficiency.
