NOVELTY - A growth-promoting anti-compacting slow release compound fertilizer comprises 1250-2000 meshes diatomite, urea, ammonium hydrogen carbonate, potassium dihydrogen phosphate, beer lees, fish slag, calcium superphosphate, peanut straw pole, copper sulfate, zinc sulfate heptahydrate, ferrous sulfate, fresh ginger juice, chitosan, gelatin, glycerol, starch, sodium alginate, acrylic acid, potassium sulfate, and additive.    USE - Growth-promoting anti-compacting slow release compound fertilizer.    ADVANTAGE - The fertilizer has rich comprehensive nutrient, low preparation cost, and more durable fertilizer effect, will not cause soil compaction in long-term use, and has multi-organic matter content and continuous increasing effect.    DETAILED DESCRIPTION - A growth-promoting anti-compacting slow release compound fertilizer comprises 10-15 pts. wt. 1250-2000 meshes diatomite, 23-25 pts. wt. urea, 20-22 pts. wt. ammonium hydrogen carbonate, 10-12 pts. wt. potassium dihydrogen phosphate, 10-12 pts. wt. beer lees, 4-5 pts. wt. fish slag, 8-10 pts. wt. calcium superphosphate, 6-8 pts. wt. peanut straw pole, 1-2 pts. wt. copper sulfate, 2-3 pts. wt. zinc sulfate heptahydrate, 1-3 pts. wt. ferrous sulfate, 1-3 pts. wt. fresh ginger juice, 6-8 pts. wt. chitosan, 12-15 pts. wt. gelatin, 4-5 pts. wt. glycerol, 2-4 pts. wt. starch, 5-6 pts. wt. sodium alginate, 10-12 pts. wt. acrylic acid, 0.1-0.2 pt. wt. potassium sulfate, and 4-5 pts. wt. additive. The additive comprises 12-15 pts. wt. poultry feather, 30-40% 30-35 pts. wt. sulfuric acid solution, sodium hydroxide, 0.15-0.2 pt. wt. keratinase, 1-2 pts. wt. copper citrate, 1-2 pts. wt. manganese citrate, 1-2 pts. wt. zinc citrate, 20-22 pts. wt. medical stone powder, and 5-6 pts. wt. sodium silicate. The additive is prepared by washing poultry feather with water, high temperature sterilizing, crushing, adding sulfuric acid solution, hydrolyzing for 15-18 hours, adding sodium hydroxide solution, regulating pH value to 6.5-7.0, heating to 50-60 degrees C, adding keratinase, enzymolyzing for 12-15 hours, adding copper citrate, manganese citrate, and zinc citrate, stirring, reacting for 2-3 hours, adding sodium silicate, continuously stirring for 30-40 minutes, adding medical stone powder, stirring, drying, and grinding for 40-50 minutes. An INDEPENDENT CLAIM is included for the preparation of fertilizer comprising:    (A) mixing peanut straw pole, beer lees, fresh fish slag, and fresh ginger juice and fermenting;    (B) mixing equal parts of water and diatomite, grinding for 20-30 minutes, adding copper sulfate pentahydrate, zinc sulfate heptahydrate, and ferrous sulfate, stirring, and drying to prepare coating material;    (C) dissolving chitosan, gelatin and sodium alginate in deionized water, heating to 60-80 degrees C, stirring, adding starch, pasting for 40-50 minutes, cooling to 40-50 degrees C, adding potassium persulfate, stirring for 20-30 minutes, slowly adding acrylic acid, continuously stirring, and reacting for 40-50 minutes to obtain sustained-released agent; and    (D) mixing product in first and second steps, granulating, adding sustained release coating agent, drying, and cooling to room temperature.
