NOVELTY - Multifunctional active organic fertilizer comprises innermost layer made of component A, middle layer made of component B and C, and outermost layer made of component D from inside to outside. The component A comprises 5-6 pts. wt. sugar powder, 18-20 pts. wt. fermented straw, 1.5-2 pts. wt. Bacillus subtilis microbial inoculum and 1.5-2 pts. wt. Paecilomyces lilacinus microbial inoculum. The component B comprises 5-5.5 pts. wt. potassium humate, 5-6 pts. wt. polylactic acid urea, 2-2.5 pts. wt. zinc sulfate and 0.01-0.02 pts. wt. rare earth.    USE - The organic fertilizer is useful for agricultural planting field.    ADVANTAGE - The fertilizer ensures passivation of heavy metal in soil, activates soil, improves rooting zone micro-ecological environment, ensures degradation of chemical pesticides, and increases crop quality.    DETAILED DESCRIPTION - Multifunctional active organic fertilizer comprises innermost layer made of component A, middle layer made of component B and C, and outermost layer made of component D from inside to outside. The component A comprises 5-6 pts. wt. sugar powder, 18-20 pts. wt. fermented straw, 1.5-2 pts. wt. Bacillus subtilis microbial inoculum and 1.5-2 pts. wt. Paecilomyces lilacinus microbial inoculum. The component B comprises 5-5.5 pts. wt. potassium humate, 5-6 pts. wt. polylactic acid urea, 2-2.5 pts. wt. zinc sulfate and 0.01-0.02 pts. wt. rare earth. The component C comprises 43-45 pts. wt. humic acid, 2-2.5 pts. wt. silicon, calcium and magnesium fertilizer and 4.5-14 pts. wt. bentonite. The component D comprises 1.5-1.8 pts. wt. Streptomyces vinaceusdrappus microbial inoculum, 1.5-2 pts. wt. Gliocladium species microbial inoculum and 0.01-0.19 pts. wt. palm oil. The effective viable count in the Bacillus subtilis microbial inoculum is not less than 109 colony forming units, the effective viable count in the Paecilomyces lilacinus microbial inoculum is not less than 108 colony forming units, the effective viable count in the Streptomyces vinaceusdrappus microbial inoculum is not less than 2x 109 colony forming units, the effective viable count in the Gliocladium species microbial inoculum is not less than 2x 109 colony forming units, and the palm oil is 44 degrees or 52 degrees palm oil. An INDEPENDENT CLAIM is also included for preparing the multifunctional active organic fertilizer, comprising (i) fermented straw to 40-80 meshes and sterilizing, and crushing component B and component C raw materials into 80-120 meshes, (ii) stirring the component A raw materials and placing at room temperature for 7 days to obtain component A, (iii) adding component B raw material and 1 pts. wt. water to a wet material mixer, stirring into a porridge-like component B, adding the component B into a slurry tank, continuing adding water and diluting into liquid, (iv) stirring and mixing component C raw materials to prepare component C, (v) melting the palm oil, adding Streptomyces vinaceusdrappus microbial inoculum and Gliocladium species microbial inoculum, stirring, pouring into a coating tank to prepare the coating solution i.e. component D, (vi) mixing component A and component C with a mixer, adding into a granulation disk, spraying component B with a spray pump on granulated disc and granulating, (vii) adding good particles into a drying cylinder, drying and secondary granulating, (viii) drying at room temperature in a secondary cooling tube, recovering dust in the drying cylinder and cooling tube by a dust chamber, and repeating the step (vi), and (ix) introducing the particles into a screening machine and coating component D to prepare multifunctional active organic fertilizer of particle size 2-4.5 mm.
