NOVELTY - Biodegradable strawberry organic fertilizer comprises sawdust, tea seed, monoammonium phosphate, attapulgite powder, urea, calcium-magnesia phosphate fertilizer, potassium sulfate, bone powder, gelatin, tree ash, glutinous rice, plant oil, refined rice bran, basalt powder, effective microorganism (EM) microbial inoculum, gibberellin, soil-modifying agent, and washed rice water. The soil modifying agent comprises e.g. borax, diatomite, oyster shell, biogas slurry, iron ore tailing slag, sea pumice stone, manganese sulfate, sodium polyacrylate, sodium alginate, and zinc sulfate.    USE - The fertilizer is used for preventing Verticillium wilt and common diseases of strawberry.    ADVANTAGE - The fertilizer uses sawdust, and wood ash organic raw material, makes strawberry root to achieve smooth absorption of microorganism decomposed organic matter, is rich in the nutrition component, and has good disease preventing effect.    DETAILED DESCRIPTION - Biodegradable strawberry organic fertilizer comprises 40-50 pts. wt. sawdust, 8-14 pts. wt. tea seed, 4-5 pts. wt. monoammonium phosphate, 6-8 pts. wt. attapulgite powder, 5-6 pts. wt. urea, 6-9 pts. wt. calcium-magnesia phosphate fertilizer, 5-6 pts. wt. potassium sulfate, 10-12 pts. wt. bone powder, 3-5 pts. wt. gelatin, 15-20 pts. wt. wood ash, 6-8 pts. wt. glutinous rice, 4-6 pts. wt. plant oil, 12-16 pts. wt. refined rice bran, 4-5 pts. wt. basalt powder, 3-4 pts. wt. effective microorganism (EM) microbial inoculum, 2-3 pts. wt. gibberellin, 4-5 pts. wt. soil-modifying agent, and washed rice water (balance). The soil modifying agent comprises 3-4 pts. wt. borax, 30-40 pts. wt. diatomite, 5-6 pts. wt. oyster shell, 4-6 pts. wt. biogas slurry, 10-12 pts. wt. iron ore tailing slag, 8-10 pts. wt. sea pumice stone, 14-18 pts. wt. pumice soil, 2-3 pts. wt. manganese sulfate, 6-8 pts. wt. sodium polyacrylate, 8-10 pts. wt. sodium alginate, 10-16 pts. wt. zinc sulfate, 8-14 pts. wt. ammonium molybdate, 15-20 pts. wt. bamboo charcoal, 6-7 pts. wt. water, and 3-4 pts. wt. tea oil. The preparation of soil modifying agent comprises mixing zinc sulfate, ammonium molybdate and bamboo charcoal, drying, grinding into fine powder, and then mixing with sodium polyacrylate, extruding into granules, adding biogas slurry, sodium alginate, and water, mixing and stirring into slurry, adding manganese sulfate and borax in slurry, stirring uniformly and low flame heating for 10-30 minutes, coating the obtained viscous material on the front surface of the particles to obtain composite granule, adding diatomite, oyster shell, iron ore tailings, sea pumice stone, and pumice soil, mixing, grinding into fine powder, sieving by 80-120 meshes sieve, dropping tea oil in the fine powder, stirring uniformly obtained paste and composite mix, and drying to obtain the product. An INDEPENDENT CLAIM is also included for preparing biodegradable strawberry organic fertilizer comprising (i) mixing sawdust, tea seed, wood ash, and refined rice bran, spraying rice water to wet, then adding EM microbial inoculum, under normal temperature, aerobic fermenting for 20-30 days, turning one time per 2-4 days to obtain the fermentation material, (ii) mixing urea, calcium-magnesia phosphate fertilizer, potassium sulfate, and monoammonium phosphate, grinding into powder, (iii) mixing attapulgite powder, bone meal, gelatin, glutinous rice, and plant oil, boiling for 20-40 minutes, adding cooking material into the step (i) obtained fermentation material and cooling, under same condition again fermenting for 5-15 days, and (iv) drying the step (iii) obtained fermentation material, mixing the remaining material uniformly, granulating, and packing into bag to obtain the product.
