USE - The complex fertilizer is used for resisting drought, plant diseases and insect pests.    ADVANTAGE - The fertilizer provides strawberry growth substance and nutrients, improves the beneficial microorganism ecological system in soil to promote growth, increases survival rate of strawberry, and realizes high-yield with low input.    DETAILED DESCRIPTION - Anti-reversion yield-increasing strawberry complex fertilizer comprises 20-30 pts. wt. fluvo-aquic soil, 6-8 pts. wt. glauconite powder, 40-60 pts. wt. chicken manure, 3-4 pts. wt. effective microorganism (EM) inoculant, 2-3 pts. wt. naphthaleneacetic acid sodium, 4-6 pts. wt. zinc sulfate, 6-8 pts. wt. ferrous sulfate, 14-18 pts. wt. silkworm dropping, 6-8 pts. wt. calcium superphosphate, 12-16 pts. wt. sawdust, 8-10 pts. wt. lobster powder, 20-26 pts. wt. sweet potato powder, 9-13 pts. wt. soybean powder, 5-6 pts. wt. sunn hemp, 5-6 pts. wt. soil modifying agent, and water (balance). The soil modifying agent comprises 3-4 pts. wt. borax, 30-40 pts. wt. diatomite, 5-6 pts. wt. raw 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, then mixing with sodium polyacrylate, extruding, 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 resulting viscous material in the front surface to obtain composite granule, mixing diatomite, raw oyster shell, iron ore tailings, sea pumice stone and pumice soil, grinding into fine powder, sieving through 80-120 meshes sieve, dropping the tea oil in fine powder, stirring uniformly to obtain paste and composite mix, and drying to obtain the product.. An INDEPENDENT CLAIM is also included for preparing complex fertilizer comprising (i) mixing dry chicken manure, and silkworm dropping, grinding into fine powder, then adding sweet potato powder, soybean powder, soaking the mixed powder in 50-70 degrees C water for 20-40 minutes, and then removing the moisture, allowing to stand wet mixed powder, adding EM inoculant, fermenting for 20-30 days at normal temperature under aerobic condition, drying fermentation material and granulating, (ii) mixing zinc sulfate, naphthaleneacetic acid sodium, ferrous sulfate, and calcium superphosphate, and rolling, (iii) adding lobster powder and sunn hemp in a steamer, adding water and low flame boiling for 40-60 minutes, cooling to room temperature, adding sawdust, fluvo-aquic soil, and glauconite powder, mixing, stirring at 600-1000 revolutions/minute for 20 minutes, drying and granulating, and (iv) mixing the step (i), (ii) and (iii) resulting material with the remaining material uniformly.
