NOVELTY - Multi-element composite fertilizer comprises Camellia seed shell, perlite, corundum, porcelain granule, nano-carbon, urea, potassium chloride, magnesium oxide, magnesium sulfate, ferric sulfate, ammonium citrate, effective microorganism (EM) inoculum, coating agent and water. The coating agent comprises dipentaerythritol hexaacrylate, silane coupling agent KH-570, nano-carbon and medical stone powder. It is prepared by mixing the raw materials, grinding and uniformly dispersing to obtain the product.    USE - Multi-element composite fertilizer used for promoting the growth of plant.    ADVANTAGE - The composite fertilizer improves the soil texture, provides high yield and high quality product, and has multiple beneficial nutrients by using inorganic raw materials.    DETAILED DESCRIPTION - Multi-element composite fertilizer comprises 120-130 pts. wt. Camellia seed shell, 10-12 pts. wt. perlite, 2-3 pts. wt. corundum, 2-3 pts. wt. porcelain granule, 1-2 pts. wt. nano-carbon, 30-34 pts. wt. urea, 20-23 pts. wt. potassium chloride, 1-2 pts. wt. magnesium oxide, 3-4 pts. wt. magnesium sulfate, 1-2 pts. wt. ferric sulfate, 2-3 pts. wt. ammonium citrate, 3-4 pts. wt. EM inoculum, 4-6 pts. wt. coating agent and water. The coating agent comprises 10-12 pts. wt. dipentaerythritol hexaacrylate, 2-3 pts. wt. silane coupling agent KH-570, 0.1-0.2 pt. wt. nano-carbon and 1-2 pts. wt. medical stone powder. It is prepared by mixing the raw materials, grinding and uniformly dispersing to obtain the product. An INDEPENDENT CLAIM is included for preparation of multi-element composite fertilizer comprising adding perlite with water, grind into slurry, adding corundum, porcelain granule and nano-carbon, continuously grinding for 5-10 minutes to obtain slurry, adding Camellia seed shell into water, soaking for 20-24 hours, adding slurry, uniformly mixing, adding EM inoculum, uniformly mixing, sealing, anaerobic fermenting at normal temperature for 25-35 days, taking out and drying to prepare into granule, adding magnesium oxide, magnesium sulfate, ferric sulfate and ammonium citrate with water, uniformly mixing by stirring to obtain mixed liquid, mixing urea and potassium chloride, heating to melt, adding the obtained mixed liquid and other remaining components, uniformly mixing, heating while stirring for 4-6 minutes, stopping heating, spray drying to obtain dry powder, adding the prepared granule, uniformly mixing and drying to obtain the product.
