NOVELTY - Plant root efficient fertilizer comprises weathered coal powder, medical stone, shell powder, earthworm, grass, dung, sugar, sweet potato slag, rice, effective microorganism (EM) liquid, ammonium molybdate, potassium sulfate, magnesium oxide, zinc sulfate, phosphate fertilizer, urea, bamboo carbon powder, plant ash, coating agent and water. The coating agent comprises divinyl benzene, calcium oxide, melamine formaldehyde resin, isopropyl alcohol, bamboo carbon powder, acetic acid, glycerin, limestone powder, sulfuric acid and water.    USE - Plant root efficient fertilizer.    ADVANTAGE - The plant root efficient fertilizer has water retention and special resin film coating, which has slow release function and is non-polluting, prevents rainwater erosion, which causes the loss of effective component, saves energy, and protects the environment.    DETAILED DESCRIPTION - Plant root efficient fertilizer comprises 15-20 pts. wt. weathered coal powder, 30-40 pts. wt. medical stone, 20-27 pts. wt. shell powder, 20-25 pts. wt. earthworm, 70-80 pts. wt. grass, 65-85 pts. wt. dung, 30-45 pts. wt. sugar, 20-25 pts. wt. sweet potato slag, 30-40 pts. wt. rice, 3-4 pts. wt. EM liquid, 5-7 pts. wt. ammonium molybdate, 8-12 pts. wt. potassium sulfate, 7-10 pts. wt. magnesium oxide, 6-8 pts. wt. zinc sulfate, 12-16 pts. wt. phosphate fertilizer, 15-20 pts. wt. urea, 10-12 pts. wt. bamboo carbon powder, 18-25 pts. wt. plant ash, 3-4 pts. wt. coating agent and water. The coating agent comprises 1-2 pts. wt. divinyl benzene, 4-6 pts. wt. calcium oxide, 3-5 pts. wt. melamine formaldehyde resin, 6-9 pts. wt. isopropyl alcohol, 3-5 pts. wt. bamboo carbon powder, 2-4 pts. wt. acetic acid, 1-2 pts. wt. glycerin, 8-10 pts. wt. limestone powder, 0.5-1 pt. wt. sulfuric acid and water. It is prepared by diluting isopropyl alcohol with 3-4 times water, adding divinylbenzene, glycerol, melamine formaldehyde resin and potassium persulfate, heating under stirring condition to dissolve, obtaining solution A, mixing calcium oxide, starch, acetic acid and limestone powder, adding to solution A, stirring into emulsion, drying and concentrating to obtain the coating agent. An INDEPENDENT CLAIM is included for preparation of plant root efficient fertilizer comprising mixing grass, dry dairy manure, sugar, sweet potato slag and rice husk, crushing, spraying with 10 times diluted EM liquid, uniformly adjusting water content to 40%, sealing for 18-20 days, overturning for every 2 days, adding shell powder, earthworm and weathered coal powder, mixing, adding to fermented material, adding water, grinding into paste, adding 60-mesh crushed medical stone, mixing ammonium molybdate, potassium sulfate, magnesium sulfate, zinc sulfate, phosphate fertilizer, urea and other raw materials, adding 4-6 times water, heating under stirring condition to dissolve, adding bamboo carbon powder and plant ash, homogenizing, drying, primary granulating, putting into coating machine, uniformly spraying with film coating, hot air drying at 60-80 degrees C for 10-15 minutes, and obtaining the product.
