NOVELTY - A fertilizer comprises 30-32 wt.% pig manure, 10-12 wt.% chicken manure, 0.02 wt.% nitrogen-fixing bacteria, 0.02 wt.% organic phosphorus decomposing bacteria, 0.02 wt.% phosphorus bacteria, 0.02 wt.% potassium bacteria, 0.02 wt.% rhizobium, 20 wt.% canal mud, 10 wt.% corn straw, 5 wt.% peanut shell, 3 wt.% fruit dregs, 4 wt.% lees, 2 wt.% monosodium glutamate, 3 wt.% cotton seed phellodendron, 1 wt.% organic fertilizer fermentation agent, 6 wt.% monoammonium phosphate, 3.7 wt.% potassium sulfate, 0.1 wt.% amino acid chelate microelement, and 0.1 wt.% humic acid chelate microelement.    USE - As a medlar base special fertilizer (claimed).    ADVANTAGE - The fertilizer is rich in organic substance, inorganic substance and amino acid chelated trace element; improves drought resistance of plant diseases, and fertilizer retention ability; and enhances the soil water retention ability. The method of making fertilizer is simple, and uses raw materials which are abundant.    DETAILED DESCRIPTION - A medlar base special fertilizer, comprises 30-32 wt.% pig manure, 10-12 wt.% chicken manure, 0.02 wt.% nitrogen-fixing bacteria, 0.02 wt.% organic phosphorus decomposing bacteria, 0.02 wt.% phosphorus bacteria, 0.02 wt.% potassium bacteria, 0.02 wt.% rhizobium, 20 wt.% canal mud, 10 wt.% corn straw, 5 wt.% peanut shell, 3 wt.% fruit dregs, 4 wt.% lees, 2 wt.% monosodium glutamate, 3 wt.% cotton seed phellodendron, 1 wt.% organic fertilizer fermentation agent, 6 wt.% monoammonium phosphate, 3.7 wt.% potassium sulfate, 0.1 wt.% amino acid chelate microelement, and 0.1 wt.% humic acid chelate microelement, and where the medlar base special fertilizer is prepared by adding pig manure and chicken manure into the fermentation tank, adding nitrogen-fixing bacteria, organic phosphorus decomposing bacteria, phosphorus bacteria, potassium bacteria, and rhizobium in prescription quantity, adding proper amount of water and uniformly mixing after sealing to ferment for 18-20 days and drying tank by the mechanical drying until the water content becomes less than 15% into the mixing tank; taking canal mud, corn straw, peanut shell, fruit dregs, lees, monosodium glutamate dreg, cotton seed, phellodendron, and organic fertilizer fermenting agent in prescription amount, and crushing into the powder crusher to the fermenting tank, adding proper amount of water and sealing to ferment for 16-18 days and drying tank by the mechanical drying until the water content becomes less than 15% into the mixing tank; and adding mono-ammonium phosphate, potassium sulfate, amino acid chelating microelement, and humic acid chelating microelement into the crusher to crush as the powder into the mixing tank, uniformly mixing the material in a mixing tank to obtain the finished product.
