NOVELTY - Photinia serrulata tree planting fertilizer comprises borax, plant ash, sawdust, peat soil, plant oil, rice hull, sodium alginate, microbial inoculum, calcium superphosphate, naphthyl acetate, potassium sulfate, boric acid, sodium pyrophosphate, water and auxiliary agent comprising polyethylene glycol, tetrachlorobenzene phthalocyanine, sodium nitrophenolate, yellow phosphorus slag, nitro ammonium humate, alum, alpha -lipoic acid, n-butanol and water.    USE - Photinia serrulata tree planting fertilizer (claimed).    ADVANTAGE - The fertilizer: increase soil organic matter content; reduces nutrient loss; improves sandy soil; improves soil function; comprises boron, which can promotes sugar transportation in the tree body and water absorption; provides warm and humid environment to achieve complete fermentation of the organic substances; meets the physiological requirements required for the tree; comprises borax and sodium alginate, which provides structural framework; dissolves chemical nutrients; has slow release effect to reduce the use of chemical fertilizers; and relieves energy crisis.    DETAILED DESCRIPTION - Photinia serrulata tree planting fertilizer comprises 8-10 pts. wt. borax, 5-6 pts. wt. plant ash, 12-14 pts. wt. sawdust, 10-14 pts. wt. peat soil, 3-4 pts. wt. plant oil, 8-12 pts. wt. rice hull, 2-3 pts. wt. sodium alginate, 2-3 pts. wt. microbial inoculum, 5-7 pts. wt. calcium superphosphate, 2-3 pts. wt. naphthyl acetate, 8-10 pts. wt. potassium sulfate, 7-9 pts. wt. boric acid, 4-6 pts. wt. sodium pyrophosphate, water and 4-5 pts. wt. auxiliary agent comprising 4-6 pts. wt. polyethylene glycol, 2-4 pts. wt. tetrachlorobenzene phthalocyanine, 3-5 pts. wt. sodium nitrophenolate, 1-12 pts. wt. yellow phosphorus slag, 6-8 pts. wt. nitro ammonium humate, 3-4 pts. wt. alum, 1-2 pts. wt. alpha -lipoic acid, 2-3 pts. wt. n-butanol and water. The preparation of the auxiliary agent comprises (a) grinding yellow phosphorus slag into fine, sieving via 200-mesh sieve, mixing with nitro ammonium humate into powder, (b) mixing polyethylene glycol and butanol in a ratio of 1:10, adding water to be dissolved, adding tetrachlorobenzene phthalocyanine, sodium nitrophenolate, ammonium alum and alpha -lipoic acid, stirring and heating to dissolve for 1-2 hours, and (c) adding the product of the step (b) into powder of the step (a), stirring uniformly, drying and crushing. An INDEPENDENT CLAIM is also included for preparing the fertilizer, comprising (i) mixing plant ash, sawdust, peat, plant oil and rice hull, primarily crushing, mixing microbial inoculum with water in a ratio of 1:10, spraying to the mixed organic material, mixing uniformly, adjusting the water content to 30%, fermenting for 16-20 days at 36-40 degrees C, and stirring once in 3 days, (ii) mixing calcium phosphate, naphthyl acetate, potassium sulfate, boric acid, sodium pyrophosphate, auxiliary agent and other residual components, adding water (4 times), stirring and heating to dissolve to obtain aqueous agent, (iii) adding sodium alginate powder into aqueous agent in a ratio of 1:80, adding water, heating and stirring to dissolve, adding borax, stirring at room temperature for 30-40 minutes and cooling into jelly compound, and (iv) mixing the product of the step (i) with jelly compound, mechanically rolling for 10-12 minutes, drying process, adjusting the water content to less than 20%, ultra-micro crushing, granulating until the grain diameter is 3-5 mm, and packing.
