Formula and film-coating preparation method for biological carbon coated urea

The invention relates to a formula and a film-coating preparation method for biological carbon coated urea. The biological carbon coated urea is characterized in that the outside of a fertilizer core is coated with solid-powder-shaped biological carbon, sulfur, dicyandiamide and bentonite by using granular urea with a size of 3 to 4 mm as the fertilizer core and oxidized corn starch as bonding liquid, wherein the above-mentioned components have weight proportions as follows: 50 to 80 parts of the urea, 10 to 30 parts of the biological carbon, 2 to 10 parts of the sulfur, 2 to 3 parts of the dicyandiamide, 2 to 3 parts of the bentonite and 3 to 5 parts of the corn starch. The film-coating preparation method for the biological carbon coated urea comprises the following steps: placing the urea into a disc granulator, carrying out preheating with hot air for 5 min, spraying the bonding liquid on the surface of the urea with a high-pressure spray gun, blowing the hot air for 3 to 5 min, adding a mixed film-coating material into the disc granulator in batches and carrying out rotating for 10 min, then spraying the bonding liquid again, and carrying out drying in the air so as to obtain the biological carbon coated urea. According to the invention, the biological carbon can improve physical and chemical properties of soil and adsorb ammonium-nitrogen and nitrate-nitrogen ions; the dicyandiamide reduces nitrification; and S4O62- generated by decomposition of the sulfur can delay decomposition of the dicyandiamide, and H+ and S2O32- generated by decomposition of the sulfur can inhibit nitrification. The biological carbon coated urea provided by the invention has the advantages of low ammonia volatilization, slow generation of nitrate nitrogen, low nitrogen loss and high nitrogen effectiveness.
