NOVELTY - Rose plant fertilizer comprises borax, podzolic soil, oil residue, bone powder, wheat bran, coal slag, soybean oil, sodium alginate, effective microorganism (EM) biological microbial inoculum, ferrous sulfate, potassium humate, ammonium bicarbonate, manganese chloride, heavy calcium phosphate, auxiliary agent and water. The auxiliary agent comprises polyethylene glycol, phthalocyanine, sodium nitrophenolate, yellow phosphorus slag, ammonium nitrohumate, ammonium alum, alpha -lipoic acid, n-butanol and water.    USE - Used as a rose plant fertilizer (claimed).    ADVANTAGE - The fertilizer: is prepared by fermenting oil residue (claimed); contains large amount of animal fat and saturated fatty acids; is suitable for Chinese rose growth; contains components, which are evenly distributed; has absorbing property; prevents nutrition loss; reduces the trivial fertilization; has slow-release property; can distribute the nutrition of the fertilizer; and achieves good fertilizer effect.    DETAILED DESCRIPTION - Rose plant fertilizer comprises 7-8 pts. wt. borax, 10-12 pts. wt. podzolic soil, 8-10 pts. wt. oil residue, 5-7 pts. wt. bone powder, 12-15 pts. wt. wheat bran, 5-7 pts. wt. coal slag, 3-4 pts. wt. soybean oil, 3-4 pts. wt. sodium alginate, 2-3 pts. wt. effective microorganism (EM) biological microbial inoculum, 7-9 pts. wt. ferrous sulfate, 5-7 pts. wt. potassium humate, 10-12 pts. wt. ammonium bicarbonate, 4-5 pts. wt. manganese chloride, 2-4 pts. wt. heavy calcium phosphate, 4-5 pts. wt. auxiliary agent, and water (specific amount). The auxiliary agent comprises 4-6 pts. wt. polyethylene glycol, 2-4 pts. wt. fthalide, 3-5 pts. wt. compound sodium nitrophenolate, 1-12 pts. wt. yellow phosphorus slag, 6-8 pts. wt. ammonium nitrohumate, 3-4 pts. wt. ammonium alum, 1-2 pts. wt. alpha -lipoic acid, 2-3 pts. wt. n-butanol, and water (specific amount). Preparation of the auxiliary agent comprises (i) grinding the yellow phosphorus slag into fine powder of 200-mesh sieve, and then mixing with ammonium nitrohumate to obtain powder; (ii) mixing polyethylene glycol and n-butanol, adding water according to ratio of 1:10 to dissolve, then adding fthalide, compound sodium nitrophenolate, ammonium alum and alpha -lipoic acid, stirring and heating to dissolve for 1-2 hours to obtain an aqueous agent; and (iii) mixing the powder obtained in the step (i) into the aqueous agent, stirring and mixing uniformly, drying, and crushing to obtain the product. An INDEPENDENT CLAIM is also included for preparing the rose plant fertilizer, comprising (i) mixing the podzolic soil, oil residue, bone powder, wheat bran, coal slag, and soybean oil, primarily crushing the EM biological microbial inoculum, adding water according to 1:10 for dissolving, then spraying on the mixed organic material, mixing uniformly, adjusting the water content to 30%, fermenting at 36-40 degrees C for 12-15 days, and stirring once for every 3 days; (ii) mixing ferrous sulfate, potassium humate, ammonium bicarbonate, manganese chloride, heavy calcium phosphate, auxiliary agent and the other remaining components, adding 5-6 times of water, heating and stirring to dissolve to obtain an aqueous agent; (iii) adding sodium alginate powder to the aqueous agent, where the ratio of the powder and aqueous agent is 1:80, then supplementing water at specific standard, heating, stirring and dissolving, then adding borax, stirring at room temperature for 20-30 minutes, and cooling into jelly compound; and (iv) uniformly mixing the organic material obtained in the step (iii) and jelly compound, mechanically rolling and stirring for 10 minutes, drying, adjusting the water content to less than or equal to 18%, ultra-micro crushing, granulating into particle diameter of 4-5 mm, qualifying, and placing in a bag-film.
