NOVELTY - Bacterial fertilizer comprises 20-24 pts. wt. oil shale semi-coke, 1-2 pts. wt. microbial immobilized matrix, 5-7 pts. wt. ammonium molybdate, 38-42 pts. wt. guano, 44-46 pts. wt. dry chicken manure, 10-14 pts. wt. beeswax, 10-14 pts. wt. sodium nitrate, and 16-18 pts. wt. swill. The microbial immobilized matrix comprises round brown nitrogen fixing bacteria, cellulose-degrading strain, silicate bacterial strain, quartz sand, Sorghum flour, fern residue, Jerusalem artichoke tubers and water.    USE - The fertilizer is useful for increasing crop yield (claimed).    ADVANTAGE - The fertilizer: utilizes natural pollution-free organic matter and beneficial microorganisms; provides variety of beneficial hormones and amino acids to the soil; contacts with the crop roots to promote the growth of crops; increases the accumulation of crop nutrients; improves the yield and quality of fruit; and achieves production increasing effect.    DETAILED DESCRIPTION - Bacterial fertilizer comprises 20-24 pts. wt. oil shale semi-coke, 1-2 pts. wt. microbial immobilized matrix, 5-7 pts. wt. ammonium molybdate, 38-42 pts. wt. guano, 44-46 pts. wt. dry chicken manure, 10-14 pts. wt. beeswax, 10-14 pts. wt. sodium nitrate, and 16-18 pts. wt. swill. The microbial immobilized matrix comprises 3-5 pts. wt. round brown nitrogen fixing bacteria, 1-3 pts. wt. cellulose-degrading strain, 1-3 pts. wt. silicate bacterial strain, 10-14 pts. wt. quartz sand, 34-36 pts. wt. Sorghum flour, 52-58 pts. wt. fern residue, 23-27 pts. wt. Jerusalem artichoke tubers, and water (specific amount). The microbial immobilized matrix is prepared by (i) squeezing out the juice of J. artichoke tubers, mixing the resulting juice with quartz sand, Sorghum flour and fern residue, placing the mixed materials in a roller, rolling at room temperature for 10-30 minutes, removing the material, then adding round brown nitrogen fixing bacteria, cellulose degrading bacteria and silicate bacterial strain to the material, adding water to maintain the water content of matrix at 50-60%, allowing to stand the resulting matrix at 28-32 degrees C, and culturing for 2-3 weeks to obtain the microbial immobilized matrix. An INDEPENDENT CLAIM is also included for preparing the bacterial fertilizer, comprising (i) adding the microbial immobilized matrix with 5 times of water, filtering, retaining the filtrate, and slowly stirring at 25-30 degrees C to obtain homogeneous composite bacterial suspension, (ii) smashing the oil shale semi-coke using a pulverizer, passing through a 50 mesh sieve to obtain homogeneous powder, and calcining at 750-850 degrees C for 30-50 minutes, (iii) mixing the guano, dry chicken manure and swill, placing in a fermentation tank to ferment the mixture for 18-22 days, drying and grinding the fermented material, passing through 80 mesh sieve, mixing sodium nitrate and ammonium molybdate along with oil shale semi-coke powder obtained in the step (ii), and granulating, (iv) placing the resulting granules in a sealed furnace, using steam to heat for 3-6 minutes, removing out, and naturally cooling at room temperature, (v) warming the beeswax to dissolve, taking 40% beeswax to spray on the surface of the particle obtained in the step (iv), then evenly spraying the composite bacterial suspension obtained in the step (i) on the particles, and finally mixing the remaining molten beeswax with the remaining materials, coating on the particle surface, and (vi) placing the resulting particles at 35-45 degrees C in dry ventilated environment to dry for 2-3 days.
