NOVELTY - A long-acting slow release compound fertilizer comprises urea, calcium superphosphate, potassium sulfate, grain particles, organic compost, shrimp powder, ammonium nitrate, copper sulfate, zinc sulfate, sodium lignin sulfonate, nanocarbon, sodium benzoate, organic silicon liquid, dried pomegranate shell, titanyl sulfate, plant ash, dried barberry rhizome, alumina, calcium propionate, and additive.    USE - Long-acting slow release compound fertilizer used for planting sesame seeds (claimed).    ADVANTAGE - The fertilizer is rich in active components, controls fertility, and has high nutrient utilization rate and nutrition substance accumulation, and high planting benefit.    DETAILED DESCRIPTION - A long-acting slow release compound fertilizer comprises 28-30 pts. wt. urea, 10-12 pts. wt. calcium superphosphate, 25-28 pts. wt. potassium sulfate, 8-10 pts. wt. grain particles, 30-25 pts. wt. organic compost, 2-3 pts. wt. shrimp powder, 10-12 pts. wt. ammonium nitrate, 1-3 pts. wt. copper sulfate, 2-3 pts. wt. zinc sulfate, 1-2 pts. wt. sodium lignin sulfonate, 0.01-0.2 pt. wt. nanocarbon, 0.01-0.02 pt. wt. sodium benzoate, 10-13 pts. wt. organic silicon liquid, 5-6 pts. wt. dried pomegranate shell, 0.1-0.2 pt. wt. titanyl sulfate, 10-12 pts. wt. plant ash, 5-7 pts. wt. dried barberry rhizome, 3-5 pts. wt. alumina, 0.01-0.02 pt. wt. calcium propionate, 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 dried pomegranate shell and dried barberry rhizome, 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 with shrimp powder and grain particles, adding water at mass ratio of 1:0.4, adding Lactobacillus acidophilus, stirring, hydrolyzing, fermenting at normal temperature for 25-30 days, filtering, adding product in first step, copper sulfate, zinc sulfate, titanyl sulfate, and additive, and stirring for 1-2 hours; (C) mixing sodium lignin sulfonate, nano carbon, and organic silicon liquid, heating to 40-50 degrees C, and stirring for 50-60 minutes; 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.
