NOVELTY - High-efficiency slow-release fertilizer comprises peanut shells, wagnerianus peel, pond sludge, chicken manure, shell powder, wheat straw, diatomite, fine silicone glue, medical stone powder, effective microorganism (EM) bacterial solution, manganese sulfate, ammonium hydrogen phosphate, sodium alginate, urea, potash fertilizer, potassium dihydrogen phosphate, plant ash, limestone powder, coating agent and water. The coating agent includes divinylbenzene, calcium oxide, melamine-formaldehyde resin, isopropanol, charcoal powder, acetic acid, glycerol, limestone, potassium persulfate and water.    USE - The fertilizer is useful for growing peanut plants (claimed).    ADVANTAGE - The fertilizer: is suitable for soft soil; can be slowly degraded; avoids frequent fertilization; can slowly release mineral elements to the soil; has good water retention; can enlarge the peanut growth; and increases production.    DETAILED DESCRIPTION - High-efficiency slow-release fertilizer comprises 30-40 pts. wt. peanut shells, 10-15 pts. wt. wagnerianus peel, 10-15 pts. wt. pond sludge, 35-50 pts. wt. chicken manure, 8-14 pts. wt. shell powder, 15-20 pts. wt. wheat straw, 20-25 pts. wt. diatomite, 5-8 pts. wt. fine silicone glue, 5-10 pts. wt. medical stone powder, 3-4 pts. wt. effective microorganism (EM) bacterial solution, 6-8 pts. wt. manganese sulfate, 12-16 pts. wt. ammonium hydrogen phosphate, 5-7 pts. wt. sodium alginate, 10-14 pts. wt. urea, 8-12 pts. wt. potash fertilizer, 7-10 pts. wt. potassium dihydrogen phosphate, 15-20 pts. wt. plant ash, 5-10 pts. wt. limestone powder, 3-4 pts. wt. coating agent, and water (specific amount). The coating agent includes 1-2 pts. wt. divinylbenzene, 4-6 pts. wt. calcium oxide, 3-5 pts. wt. melamine-formaldehyde resin, 6-9 pts. wt. isopropanol, 3-5 pts. wt. charcoal powder, 2-4 pts. wt. acetic acid, 1-2 pts. wt. glycerol, 8-10 pts. wt. limestone, 0.5-1 pts. wt. potassium persulfate, and water (specific amount). Preparation of the coating agent comprises (a) diluting isopropanol in 3-4 times of water, adding divinylbenzene, glycerol, melamine-formaldehyde resin and potassium persulfate, heating, and stirring to dissolve, and (b) mixing calcium oxide, starch, limestone powder and acetic acid and adding to the resulting solution from step (a), stirring into the emulsion, drying and concentrating. An INDEPENDENT CLAIM is also included for preparation of the high-efficiency slow-release fertilizer, comprising (i) mixing the peanut shells, wagnerianus peel, chicken manure and wheat straw, preliminary grinding, spraying with 10 times of water to dilute EM bacterial solution, adjusting the water content of the mix to 40%, accumulating fermenting for 20-22 days and agitating once in every two days, (ii) adding fine silicone glue to the fermentation stock, grinding in a homogenizer, adding water, stone powder, shell powder and diatomite and mixing to obtain a paste, (iii) mixing manganese sulfate, ammonium hydrogen phosphate, sodium alginate, urea, potash fertilizer, potassium dihydrogen phosphate and other remaining ingredients, adding 4- 6 times water, heating and stirring for 30-40 minutes, mixing ash and limestone powder, preliminary drying and granulating, and (iv) placing the particles obtained in the step (iii) in a coating machine, spraying a coating agent on the fertilizer particles at 60-80 degrees C, hot-air drying for 10-15 minutes, outsourcing the ingredients, uniformly coating on the particles surface, and drying.
