DETAILED DESCRIPTION - A high efficiency long-acting bio-organic composite coated fertilizer comprises 35-45 pts. wt. paper pulp, 27-33 pts. wt. tree bark, 34-38 pts. wt. leaves, 45-48 pts. wt. traditional Chinese medicine slag, 1-2 pts. wt. borax, 1-2 pts. wt. zinc sulfate, 8-11 pts. wt. peat, 9-12 pts. wt. medical stone, 3-5 pts. wt. magnesium oxide, 6-8 pts. wt. talc powder, 26-33 pts. wt. rock phosphate, 19-25 pts. wt. potassium mineral powder, 10-14 pts. wt. flour, 5-8 pts. wt. EM inoculants, 17-19 pts. wt. polyacrylamide, 15-19 pts. wt. urea, 8-10 pts. wt. soil improving agent, and water. The soil improving agent comprises 10-20 pts. wt. bamboo charcoal, 1-2 pts. wt. nano-carbon powder, 4-5 pts. wt. sodium metasilicate, 17-19 pts. wt. methyl methacrylate, 3-4 pts. wt. yeast selenium, 2-3 pts. wt. copper sulfonate, 2-3 pts. wt. zinc gluconate, 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, 2-3 pts. wt. citric acid, 1-2 pts. wt. nano-titanium dioxide, 2-3 pts. wt. ammonium persulfate, and 1-2 pts. wt. methyl triethoxysilane. The soil improving agent is prepared by mixing methyl methacrylate, dipentaerythritol hexaacrylate, bamboo charcoal, nanocarbon powder, eucalyptus oil, nano-titanium dioxide, ammonium sulfate, and methyl triethoxysilane to form a mixture; mixing with sodium metasilicate, yeast selenium, copper sulfonate, zinc gluconate, magnesium chloride, ammonium citrate, boric acid, vinegar, chitosan, citric acid, and ammonium persulfate to obtain a vinegar solution, and high-speed dispersing into slurry.
