NOVELTY - Sustained-release bio-organic medicinal fertilizer comprises 12-24 pts. wt. kelp, 20-35 pts. wt. dregs, 25-30 pts. wt. tea seed cake, 10-20 pts. wt. Veratrum, 8-20 pts. wt. cumin, 6-16 pts. wt. xylitol residue, 18-29 pts. wt. humic acid, 13-22 pts. wt. rice bran, 4-7 pts. wt. effective microorganism inoculum, 2-6 pts. wt. urea, 20-40 pts. wt. potassium chloride, 30-55 pts. wt. ammonium phosphate, 5-10 pts. wt. manganese sulfate, 10-15 pts. wt. borax and biodegradable coating materials.    USE - The fertilizer is useful for Chinese goosebeery (claimed), and controlling pests and diseases.    ADVANTAGE - The fertilizer has long lasting effect, increased production efficiency, and good fertilization effect; meets the physiological requirements of crops, after fertilization; does not produce residues in soil, due to good biodegradable effect; is environmental friendly; and promotes organic agriculture development.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing fertilizer, comprising (i) crushing kelp, dregs, tea seed cake, Veratrum, cumin and xylitol residue used as organic raw materials, and then uniformly mixing adding humic acid, rice bran and EM inoculums; (ii) mixing first half of fermentation composting material, stacking while carrying out fermentation, controlling the material temperature at 55-60 degrees C, fermenting once in every 8-13 days, over-turning the materials 1-3 times a day, and adding the remaining half amount of fermentation composting materials, mixing, and drying, to obtain fermented organic fertilizer; (iii) adding fermented organic fertilizer with urea, potassium chloride, ammonium phosphate, manganese sulfate, borax and nematode, and mixing by adding 20-30 pts. wt. Bacillus powder, crushing, and sieving, then heating at 40-45 degrees C, adding 3-5 pts. wt. biodegradable coating materials, under pump pressure of 0.1 MPa, and spraying at a rate of 0.06 l/minute, continuously spraying for 5 minutes, uniformly spraying fertilizer on the surface of the materials, coating liquid by spraying completely, maintaining at 40-45 degrees C for 10 minutes, and carrying out hot air drying the fertilizer; and (iv) packaging once the fertilizer temperature is more than 30 degrees C, adding hydrophobic powder materials, to obtain the final product.
