NOVELTY - Fertilizer comprises maifanite, diatomite, citric acid, calcium nitrate, rice hull, moonstone, Narcissus tazetta root, rapeseed cake, phosphate rock powder, coal gangue, potassium sulfate, magnesium sulfate, silicate bacteria, silicon-substituted hydroxyapatite, and auxiliary agent. The auxiliary agent contains iron ore powder, fresh potato, amino acid chelated magnesium, amino acid chelated copper, amino acid chelated boron, amino acid chelated manganese, methyl methacrylate, N-butylthio triamide, fresh grass, and coral limestone.    USE - The fertilizer is useful for promoting metabolism (claimed) and growth of crops.    ADVANTAGE - The fertilizer reduces secretion of gibberellin by crops. The utilization rate of fertilizer by soil is improved.    DETAILED DESCRIPTION - Fertilizer comprises 6-8 pts. wt. maifanite, 12-16 pts. wt. diatomite, 3-4 pts. wt. citric acid, 2-3 pts. wt. calcium nitrate, 50-60 pts. wt. rice hull, 4-6 pts. wt. moonstone, 6-9 pts. wt. Narcissus tazetta root, 75-95 pts. wt. rapeseed cake, 4-5 pts. wt. phosphate rock powder, 3-5 pts. wt. coal gangue, 2-3 pts. wt. potassium sulfate, 1-3 pts. wt. magnesium sulfate, 2-4 pts. wt. silicate bacteria, 4-7 pts. wt. silicon-substituted hydroxyapatite, and 5-7 pts. wt. auxiliary agent. The auxiliary agent comprises 4-6 pts. wt. iron ore powder, 3-6 pts. wt. ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (EDDHA) chelated iron, 8-10 pts. wt. fresh potato, 3-4 pts. wt. amino acid chelated magnesium, 3-4 pts. wt. amino acid chelated copper, 3-4 pts. wt. amino acid chelated boron, 3-4 pts. wt. amino acid chelated manganese, 1-3 pts. wt. methyl methacrylate, 0.1-0.2 pt. wt. N-butylthio triamide, 12-16 pts. wt. fresh grass, and 8-12 pts. wt. coral limestone. The auxiliary agent is prepared by (i) rinsing the fresh potato and fresh grass using purified water, adding the fresh potato and fresh grass to mortar, crushing obtained mixture for 20-40 minutes, filtering the mixture, and collecting filtrate, (ii) crushing the coral limestone and iron ore to obtain powder, mixing the powder with EDDHA chelated iron, amino acid chelated magnesium, amino acid chelated copper, amino acid chelated boron, amino acid chelated manganese and filtrate obtained in step (i), uniformly stirring obtained mixture, subjecting the mixture to wet granulation to obtain granules having particle diameter of 2-4 mm, and (iii) mixing the granules with methyl methacrylate and N-butylthio triamide, and drying and cooling obtained product. An INDEPENDENT CLAIM is included for method for preparing the fertilizer, which involves (a) adding the rapeseed cake, diatomite, citric acid and phosphate rock powder, then adding suitable amount of water and 0.5 wt.% effective microbial (EM) agent to obtained mixture, performing anaerobic fermentation for 6-9 days, and controlling water content of mixture at 40% during fermentation, (b) adding the rice hull, maifanite, N.tazetta root, coal gangue and fermented product obtained in step (a) to fermentation tank, then adding 0.3 wt.% Bacillus subtilis agent, controlling water content of mixture at 50%, performing aerobic fermentation at 45-60 degrees C for 60-72 hours, adding 0.2 wt.% Aspergillus niger agent to mixture, fermenting the mixture for 16-18 days, and drying fermented product, (c) subjecting moonstone and silicon-substituted hydroxyapatite to steam sterilization at 1.05 kg/cm2 for 50-70 minutes, and crushing sterilized components to obtain powder, and (d) mixing products obtained in steps (b) and (c), adding the silicate bacteria, potassium sulfate, magnesium sulfate, calcium nitrate and auxiliary agent and remaining components to obtained mixture, uniformly mixing and adding 0.8 wt.% rare earth element as binder, uniformly stirring obtained mixture to obtain product having particle diameter of 8-12 mm, and drying the product at low temperature.
