USE - Liquid fertilizer used for improving soil structure (claimed) and promoting growth of crops.    ADVANTAGE - The fertilizer supplies nutrients.    DETAILED DESCRIPTION - A liquid fertilizer comprises 2-5 pts. wt. magnesium oxide, 4-8 pts. wt. stem of noble dendrobium wither metabolic flower, 4-5 pts. wt. medical stone, 3-4 pts. wt. zinc sulfate heptahydrate, 6-7 pts. wt. onion stalk, 4-6 pts. wt. sodium phosphate, 6-8 pts. wt. biogas slurry, 2-4 pts. wt. sodium molybdate, 5-6 pts. wt. ammonium molybdate, 2-4 pts. wt. boric acid, 0.2-0.3 pt. wt. thiourea, 5-8 pts. wt. tung tree liquid, 3-6 pts. wt. bagasse, 8-10 pts. wt. pine powder, 8-12 pts. wt. complexing agent. The complexing agent comprises 6-8 pts. wt. turtle shell, 4-6 pts. wt. Bostaurus domesticus, 3-5 pts. wt. calcium-chelated amino acid, 3-5 pts. wt. manganese-chelated amino acid, 3-5 pts. wt. zinc-chelated amino acid, 3-5 pts. wt. magnesium-chelated amino acid, 3-5 pts. wt. iron-chelated EDTA, 4-7 pts. wt. rare earth, 3-4 pts. wt. effective microorganism (EM) inoculum, 8-14 pts. wt. aquaculture waste, 15-20 pts. wt. bird manure, 5-7 pts. wt. Tenebrio molitor powder, 3-4 pts. wt. volcanic rock, and 2-3 pts. wt. chromite spinel. The complexing agent is prepared by taking aquaculture waste, bird excrement, Tenebrio molitor powder, and EM microbial inoculum, mixing, fermenting for 3-5 days, keeping water content at 30-50%, aerobic fermenting for 6-10 days, pressing to obtain fermentation liquid, and standing for 3-5 hours to obtain first solution; mixing turtle shell and Bostaurus domesticus, adding phosphoric acid solution, hydrolyzing, neutralizing with lime, dissolving, filtering, adding rare earth, volcanic rock, and chromite spinel, mixing, grinding into powder, adding 300-400 times water, stirring for 2-3 hours, and filtering to form second solution; mixing calcium-chelated amino acid, manganese-chelated amino acid, zinc-chelated amino acid, magnesium-chelated amino acid, and iron-chelated EDTA, adding 200-300 times water, stirring for 90-120 minutes at 40-60 degrees C, and filtering to obtain third solution; and mixing prepared solutions. An INDEPENDENT CLAIM is included for preparation of fertilizer comprising taking medical stone, bagasse, and pine powder, mixing, adding 200-250 times water, stirring for 30-50 minutes, and filtering to obtain first nutrient liquid; taking onion stalk and dendrobium stem wither metabolic petals, grinding for 10-30 minutes, and filtering; taking magnesium oxide, zinc sulfate heptahydrate, phosphoric acid, sodium molybdate, ammonium molybdate, and boric acid, mixing, adding 250-300 times water, heating to 60-80 degrees C for 1 hour, adding biogas slurry, cooling, adding thiourea and tung tree liquid, stirring for 40-50 minutes, and filtering; and mixing prepared components and remaining raw materials, filtering, and packing.
