The auxiliary agent contains cinnamon oil, sodium dodecylbenzenesulfonate, manganese sulfate, casein phosphopeptide, sodium bicarbonate and alpha -lipoic acid.    USE - The special long-acting slow-release fertilizer is useful for cultivation of sugarcane (claimed).    ADVANTAGE - The fertilizer increases yield and quality of sugarcane, and has excellent long-acting and slow-release effects.    DETAILED DESCRIPTION - Special long-acting slow-release fertilizer comprises 0.5-1 pt. wt. copper sulfate, 8-10 pts. wt. calcium nitrate, 1-3 pts. wt. yeast, 15-18 pts. wt. brewery filtrate, 15-18 pts. wt. rapeseed cake, 5-8 pts. wt. wood chips, 2-3 pts. wt. fulvic acid, 8-10 pts. wt. humic acid, 13-14 pts. wt. attapulgite, 3-5 pts. wt. banana peel, 1-2 pts. wt. ammonium polyphosphate, 0.1-0.2 pts. wt. pentaerythritol, 8-10 pts. wt. polyvinyl alcohol, 4-5 pts. wt. zinc borate, 6-8 pts. wt. aluminum hydroxide, 3-5 pts. wt. Canna leaves, 6-8 pts. wt. goosegrass, 12-14 pts. wt. mud, 8-9 pts. wt. pseudoginseng residue, 1-2 pts. wt. alpha -amylase, 0.2-0.3 pts. wt. astaxanthin powder, and 3-5 pts. wt. auxiliary agent. The auxiliary agent comprises 1-3 pts. wt. cinnamon oil, 1-2 pts. wt. sodium dodecylbenzenesulfonate, 2-3 pts. wt. manganese sulfate, 4-5 pts. wt. casein phosphopeptide, 0.01-0.02 pt. wt. nanocarbon, 6-8 pts. wt. sodium carboxymethyl starch, 2-3 pts. wt. sodium bicarbonate and 1-2 pts. wt. alpha -lipoic acid. The auxiliary agent is prepared by mixing sodium dodecylbenzenesulfonate with 10 times water, heating mixture at 55-65 degrees C, completely dissolving mixture, then adding cinnamon oil, manganese sulfate, casein phosphopeptide and nanocarbon, stirring mixture for 40-50 minutes, finally adding other raw materials to mixture, continuously stirring mixture for 2 hours, and naturally cooling to room temperature. An INDEPENDENT CLAIM is included for method for preparing the fertilizer, which involves (a) mixing wood chips, goosegrass, and pseudoginseng residue, crushing mixture at 400-500 degrees C for 1-2 hours to obtain powder of 80 mesh sieve, adding 8-10% diluted hydrochloric acid solution to the powder, maintaining mixture for 3-4 hours, filtering mixture, and drying mixture, (b) mixing filtrate, rapeseed cake, banana peel, Canna leaves and mud with water in a weight ratio of 1:0.3, adding yeast, alpha -amylase, stirring mixture, fermenting mixture for 30-35 days, adding dried powder of step (a), copper sulfate, zinc borate, astaxanthin powder, and auxiliary agent to the fermented mixture, and uniformly stirring mixture for 1-2 hours to prepare slurry, (c) mixing polyvinyl alcohol with water, heating mixture at 60-80 degrees C, adding pentaerythritol and ammonium polyphosphate, and uniformly mixing materials for 1-1.2 hours, and (d) mixing slurry of step (b) with mixture of step (c) and other raw materials, adding obtained mixture into coating device, controlling temperature of the device to 50-60 degrees C, drying obtained particles and naturally cooling dried products.
