NOVELTY - Fruit tree special fertilizer comprises calcium superphosphate, urea, monoammonium phosphate, potassium chloride, earthworm manure, straw biological black charcoal, wood vinegar, ferrous sulfate, zinc sulfate, manganese sulfate, effective microorganism (EM) inoculum, coating agent, and water. The coating agent comprises pts. wt. dimethyl silicone oil, butyl methacrylate, crosslinking agent i.e. triallyl cyanurate (TAC), nanocarbon, medical stone powder and orthoboric acid. It is prepared by mixing the raw materials, grinding and uniformly dispersing to obtain the product.    USE - Fruit tree special fertilizer used for preventing and treating underground plant diseases and insect pests.    ADVANTAGE - The fruit tree special fertilizer has rich nutrients, increases the yield and quality of fruit tree, provides all the nutrients needed for the growth process, promotes the ecological balance of soil, adjusts the pH of soil, maintains soil moisture, enhances air permeability of soil and improves the temperature of soil surface.    DETAILED DESCRIPTION - Fruit tree special fertilizer comprises 34-38 pts. wt. calcium superphosphate, 20-24 pts. wt. urea, 20-23 pts. wt. monoammonium phosphate, 16-19 pts. wt. potassium chloride, 40-45 pts. wt. earthworm manure, 10-12 pts. wt. straw biological black charcoal, 10-12 pts. wt. wood vinegar, 3-4 pts. wt. ferrous sulfate, 2-3 pts. wt. zinc sulfate, 3-4 pts. wt. manganese sulfate, 3-4 pts. wt. EM inoculum, 4-6 pts. wt. coating agent, and water. The coating agent comprises 12-15 pts. wt. dimethyl silicone oil, 13-16 pts. wt. butyl methacrylate, 1-2 pts. wt. crosslinking agent i.e. TAC, 0.1-0.2 pt. wt. nanocarbon, 1-2 pts. wt. medical stone powder and 1-2 pts. wt. orthoboric acid. It is prepared by mixing the raw materials, grinding and uniformly dispersing to obtain the product. An INDEPENDENT CLAIM is included for preparation of fruit tree special fertilizer comprising grinding straw biological black charcoal and wood vinegar to obtain slurry, mixing with calcium phosphate, urea, monoammonium phosphate and potassium chloride, adding water and uniformly stirring to obtain mixed liquid, adding ferrous sulfate, zinc sulfate and manganese sulfate with water, fully stirring to completely dissolve, adding earthworm manure and uniformly mixing to obtain mixed material, uniformly mixing the mixed liquid and mixed material, adding EM inoculum and other remaining components, uniformly mixing by stirring, maintaining at 45-70 degrees C, fermenting for 15-20 days, turning for 3-4 times, adding the fermentation material into a drier, drying and preparing into granule to obtain the product.
