Embodiment 1
[0020] A kind of multifunctional carbon-based organic-inorganic compound fertilizer, its raw material is by weight percentage:
[0021] Urea 5%;
[0022] Formaldehyde 5%;
[0023] Bacteria residue black charcoal 25%;
[0024] Calcium magnesium phosphorus 30%;
[0026] Attapulgite 10%;
[0027] Kaolin 5%.
[0028] A multifunctional carbon-based organic-inorganic compound fertilizer, which is made by mixing urea with water and other qualities, dissolving it and raising the temperature to 40°C, adjusting it to weak alkaline (pH 7.0) with sodium hydroxide solution; adding 40% formaldehyde aqueous solution React for 1.5 hours, adjust to acidic (pH 3.5) with phosphoric acid solution, and filter at 40°C for 1.5 hours; take out the mixture, add crushed fungal residue black carbon and stir well, then add crushed calcium magnesium phosphorus, sulfuric acid Potassium, attapulgite, kaolin, and then mixed and stirred evenly, granulated, dried at 60-80°...
