NOVELTY - A multiple-effect composite coated fertilizer, comprises: 22-25 pts. wt. nitrogenous fertilizer, 17-19 pts. wt. potassium dihydrogen phosphate, 0.5-1 pts. wt. mancozeb, 55-59 pts. wt. animal bone powder, 44-48 pts. wt. animal hair, 56-60 pts. wt. leaves, 2-3 pts. wt. sodium lignosulfonate, 17-19 pts. wt. sodium carboxymethyl starch, 4-6 pts. wt. EM microbial inoculum, 6-9 pts. wt. attapulgite, 10-13 pts. wt. calcium superphosphate, 7-9 pts. wt. soil improving agent, and water. The soil modifying agent comprises: e.g. long oil degree alkyd resin, nano-carbon powder and sodium silicate.    USE - As multiple-effect composite coated fertilizer (claimed); and for reducing the incidence of pest diseases.    ADVANTAGE - The multiple-effect composite coated fertilizer adds plant bactericide in the fertilizer, at the same time satisfies need of plant growth nutrients with sterilizing function; reduces the incidence of pests diseases; adds soil amendments, with synergistic and promoting plant absorbing nutrition. The coating process obviously enhances slow release effect, but also saves the cost and is suitable for popularization.    DETAILED DESCRIPTION - A multiple-effect composite coated fertilizer, comprises: 22-25 pts. wt. nitrogenous fertilizer, 17-19 pts. wt. potassium dihydrogen phosphate, 0.5-1 pts. wt. mancozeb, 55-59 pts. wt. animal bone powder, 44-48 pts. wt. animal hair, 56-60 pts. wt. leaves, 2-3 pts. wt. sodium lignosulfonate, 17-19 pts. wt. sodium carboxymethyl starch, 4-6 pts. wt. EM microbial inoculum, 6-9 pts. wt. attapulgite, 10-13 pts. wt. calcium superphosphate, 7-9 pts. wt. soil improving agent, and water. The soil modifying agent comprises: 10-20 pts. wt. long oil degree alkyd resin, 1-2 pts. wt. nano-carbon powder, 4-5 pts. wt. sodium silicate, 17-19 pts. wt. methyl methacrylate, 3-4 pts. wt. yeast selenium, 2-3 pts. wt. copper, 2-3 pts. wt. zinc, 1-2 pts. wt. magnesium chloride, 2-3 pts. wt. ammonium citrate, 1-2 pts. wt. boric acid, 4-6 pts. wt. dipentaerythritol hexaacrylate, 30-40 pts. wt. vinegar, 2-3 pts. wt. chitosan, 1-2 pts. wt. eucalyptus oil, 3-5 pts. wt. tripropylene glycol diacrylate, 5-6 pts. wt. alum and 1-2 pts. wt. iron ore slag. Preparation of soil modifying agent, involves: mixing methyl methacrylate, dipentaerythritol hexa-acrylic ester, tripropylene glycol diacrylate and long oil degree alkyd resin, nano-carbon powder, eucalyptus oil, and iron slag uniformly, stirring, heating to 65-75 degrees C, forming mixture, and then mixing the rest residual components, fully stirring to form vinegar liquid mix, mixing the mixture and the edible vinegar liquid mix, and high speed dispersing into slurry to obtain the product. An INDEPENDENT CLAIM is included for preparation of the multiple-effect composite coated fertilizer, involving: (1) mixing nitrogen fertilizer, potassium dihydrogen phosphate, calcium superphosphate and attapulgite, adding water, mixing uniformly, adding soil modifier, mancozeb, sodium lignin sulfonate, continuing to stir uniformly, high speed dispersing, concentrating slurry, drying concentrate to prepare granule; (2) removing the residual component, uniformly mixing other than the rest carboxymethyl starch, maintaining the water content 41-45%, stirring uniformly, sealing, fermenting under normal temperature low oxygen-free process to ferment for 21-28 days, turning once every 3-5 days, drying to prepare granule; and (3) adding the step (1) and step (2) mix into a fluidized bed coating machine, where fluidized bed coating machine air inlet temperature is 75-100 degrees C, holding the air inlet pressure control in a suspended state, dissolving the sodium carboxymethyl starch in water, heating to 45-50 degrees C, and then spraying and coating mix, cooling and sieving to obtain the product.
