Abstract

The invention discloses a coarse biochar slow-release fertilizer and a preparation method thereof. The coarse biochar slow-release fertilizer is prepared from the following raw materials in parts by weight: 70-80 parts of crop straw, 5-8 parts of 1 mol/L hydrochloric acid solution, 6-10 parts of quartz sand, 6-10 parts of attapulgite, 20-30 parts of peat soil, 15-20 parts of ground phosphorite, 12-16 parts of potassium permanganate, 14-19 parts of urea, 10-15 parts of potassium dihydrogen phosphate, 9-14 parts of ammonium sulfate, 4-5 parts of adhesive and a proper amount of water. The method lays stress on reutilization of the straw. The straw is subjected to simple treatment and used in the slow-release agent for fertilizer production, thereby performing important slow-release function. The specific treatment process comprises the following steps: softening the straw by immersion, grinding, and carrying out high-temperature carbonization in a closed carbonization furnace; and in order to enhance the effect, cleaning the surface with the dilute hydrochloric acid to expose the nano adsorptive micropores. When contacting the dissolved inorganic fertilizer components under the ultrasonic actions, the straw has obvious slow-release effect, thereby being energy-saving and environment-friendly.
