DETAILED DESCRIPTION - A high-nutrition low-cost grape organic fertilizer comprises 30-35 pts. wt. dairy manure, 22-36 pts. wt. pond sludge, 11-19 pts. wt. rapeseed rice bran, 10-16 pts. wt. urea, 10-16 pts. wt. waste tea, 8-14 pts. wt. spinach, 8-10 pts. wt. pine needle powder, 6-8 pts. wt. weathered coal, 4-5 pts. wt. magnesium sulfate, 5-6 pts. wt. boron powder, 4-6 pts. wt. humic acid, 5-6 pts. wt. activated carbon, 4-5 pts. wt. effective microorganisms, 3-5 pts. wt. wood chips, 2-3 pts. wt. vitamin, and balance water and soil modifier. The soil modifier comprises 18-24 pts. wt. soil slurry, 14-18 pts. wt. biogas, 10-15 pts. wt. birch sawdust, 9-16 pts. wt. maple leaves, 8-12 pts. wt. fresh bush, 6-8 pts. wt. Crotalaria leaves, 6-7 pts. wt. fulvic acid, 5-8 pts. wt. nanocarbon powder, 4-7 pts. wt. white turnip, 5-6 pts. wt. zinc gluconate, 4-6 pts. wt. straw, 4-6 pts. wt. white cayratia, 3-5 pts. wt. calcium hydrophosphate and 4-5 pts. wt. calcium cyanamide. It is prepared by: (A) mixing marsh soil and white slurry, sintering for 40-60 minutes, grinding into fine powder, adding white cayratia and Crotalaria leaves and wrapping with white cloth; (B) grinding calcium hydrophosphate, calcium cyanamide and zinc gluconate into powder, mixing and stirring into paste; (C) pressing fresh bush, crushing, adding fulvic acid, white turnip, birch sawdust, maple leaves and water, composting for 15-20 days and nanocarbon powder every 2-4 days; and (D) uniformly mixing prepared materials and drying. An INDEPENDENT CLAIM is included for preparation of high-nutrition low-cost grape organic fertilizer comprising:    (A) adding pond sludge into sealed container, adding dairy manure, humic acid, weathered coal and pine needle powder and composting at 30-50 degrees C for 30-40 days to obtain mixed material;    (B) mixing wood chips, rapeseed rice bran, waste tea, spinach and effective microorganisms microbial inoculum, adding water and fermenting at room temperature for 20-30 days to obtain fermentation material;    (C) mixing urea, magnesium sulfate, boron powder, vitamin, activated carbon and water and uniformly stirring into paste; and    (D) adding mixed material, fermentation material and remaining components, drying, granulating and uniformly mixing.
