USE - High fertility special slow-release compound fertilizer used for planting sugarcane (claimed).    ADVANTAGE - The fertilizer has lasting fertilizer effect, high absorption and utilization rate, and high nutrient content. The sugarcane has high sweetness.    DETAILED DESCRIPTION - A high fertility special slow-release compound fertilizer comprises 15-18 pts. wt. bran, 6-8 pts. wt. black humic acid, 8-10 pts. wt. humic acid, 10-12 pts. wt. shiitake mushroom rod, 8-10 pts. wt. tea tree mushroom stick, 12-15 pts. wt. sorghum straw, 3-5 pts. wt. weathered coal, 5-6 pts. wt. sweet potato powder, 25-30 pts. wt. grass peat, 6-8 pts. wt. cellulose ether, 4-5 pts. wt. starch ether, 3-5 pts. wt. sodium tetraborate, 1-2 pts. wt. silicone oil, 0.1-0.2 pt. wt. taurine, 2-4 pts. wt. glutamine, 1-3 pts. wt. black alum, 0.2-0.3 pt. wt. Tween 80 (RTM: polyoxyethylene (20) sorbitan monooleate), 6-8 pts. wt. bamboo shell, 10-12 pts. wt. potassium metabisulfite, 15-18 pts. wt. kelp waste slag, 12-15 pts. wt. tripotassium citrate, and 3-5 pts. wt. additive. The additive comprises 1-3 pts. wt. cinnamon oil, 1-2 pts. wt. sodium dodecyl benzene sulfonate, 2-3 pts. wt. manganese sulfate, 4-5 pts. wt. casein phosphopeptide, 0.01-0.02 pt. wt. nano carbon, 6-8 pts. wt. sodium carboxymethyl starch, 2-3 pts. wt. sodium bicarbonate, and 1-2 pts. wt. alpha -lipoic acid. The additive is prepared by mixing sodium dodecyl benzene sulfonate with 10 times water, heating at 55-65 degrees C, stirring, adding cinnamon oil, manganese sulfate, casein phosphopeptide, and nano carbon, stirring for 40-50 minutes, adding residual materials, continuously stirring for 1-2 hours, and naturally cooling to room temperature. An INDEPENDENT CLAIM is included for the preparation of fertilizer comprising (A)mixing bran and bamboo shell, crushing, sieving, carbonizing at 400-500 degrees C for 1-2 hours, soaking in 8-10% diluted hydrochloric acid, activating for 3-4 hours, filtering, washing until neutral, and drying; (B) mixing shiitake mushroom rod, tea tree mushroom stick, sorghum straw, and kelp waste slag, crushing, adding water at mass ratio of 1:0.3, adding composite microbial inoculum, stirring, hydrolyzing, fermenting at normal temperature for 25-30 days, filtering, adding product in first step, sodium alum, glutamine, and additive, and stirring for 1-2 hours; (C) mixing cellulose ether, starch ether, and Tween 80 (RTM: polyoxyethylene (20) sorbitan monooleate), adding 2-3 times water, heating to 50-60 degrees C, stirring, adding silicone oil, and stirring for 1-2 hours; and (D) mixing product in second step with residual materials, granulating at 50-60 degrees C, spraying product in third step, natural cooling, and drying.
