TECHNOLOGY FOCUS - FOOD - Preferred Compositions: Earthworm feed contains 40-50 pts. wt. biodegradable garbage, 1-3 pts. wt. microbial degradation bacteria, 10-16 pts. wt. herbal dregs, 20-30 pts. wt. chicken manure, and 50-60 pts. wt. sludge. Earthworm feed contains 10-20 pts. wt. Astragalus, 10-20 pts. wt. Angelica, 20-30 pts. wt. atractylodes, 10-20 pts. wt. hawthorn, 10-20 pts. wt. Endothelium corneum gigeriae galli, 10-20 pts. wt. dried orange peel, 10-20 pts. wt. tuckahoe, 10-20 pts. wt. coix seed, 10-20 pts. wt. Uncaria, 10-20 pts. wt. sargentgloryvine stem, 10-20 pts. wt. Selaginella, and 20-30 pts. wt. licorice. Microbial degradation bacteria is Bacillus subtilis agent:Lactobacillus lichens with mass ratio 1:1. Enrichment broth through Lactobacillus lichens contains 180-220 g potato, 18-22 g glucose, and 1000 ml distilled water with pH value of 6-6.2 and fermentation broth through Lactobacillus lichens contains 5-5.5 g corn flour, 5-5.5 g soybean meal, 5-5.5 g peanut, 2.5-3 g monopotassium phosphate, 0.25-0.3 g magnesium sulfate, 0.25-0.3 g calcium chloride, 0.24-0.3 g urea, 5-5.3 g brown sugar, and 1000 ml distilled water with pH value of 5.5-6. Preferred Processes: Microbial degradation bacteria is prepared by subjecting Lactobacillus e.g. Lactobacillus lichens and into activation for 24 hours at 32-36 degrees C, inoculating enrichment culture liquid and culturing for 24 hours at 32-36 degrees C in which culturing speed is 220-250 rpm, adding 2-5 vol.% enrichment broth into aerobic fermentation broth and culturing at 32-36 degrees C with centrifugation speed of 170-200 rpm, ventilation rate of 0.8-1 L/minute, aerating over 0.45 mu m membrane filter sterilization, performing aerobic fermentation for 20-24 hours, and naturally drying at 30 degrees C to obtain product which contains 1010-11 cfu/g bacterial agent in which enrichment broth contains 5-6 g sodium chloride, 5-6 g peptone, 2.5-3 g beef powder, 1000 ml distilled water with pH value of 7-7.2 and fermentation broth contains 45-50 g glucose, 10-20 g magnesium sulfate, 10-30 g potassium dihydrogen phosphate, 10-50 g dipotassium hydrogen phosphate, and 1000 ml distilled water with pH value of 7-7.2. Earthworm feed is prepared by sorting and classifying domestic garbage, collecting biodegradable garbage through artificial machine, removing glass, plastic, metal, rubber, and ceramic components, mixing microbial degradation bacteria, sludge, herbal dregs, and chicken manure with biodegradable garbage, adjusting water content on composition to 30-40%, and allowing biodegradable anaerobic fermentation at room temperature for 6-8 days in which carbon:nitrogen ratio is 15-20:1.
