NOVELTY - Biofertilizer with rural waste is prepared by taking 40-60 pts. wt. manure, 20-30 pts. wt. mushroom stock, 20-30 pts. wt. crop straw and 0.5-1 pt. wt. bio-fermentation agents, mixing in fermentation tank, fermenting at 50-60 degrees C with humidity of 70-80%, stirring once every 1 hour, transporting in processing equipment and carrying out environmental treatment for 3-5 days.    USE - Method for preparing biofertilizer with rural waste (claimed).    ADVANTAGE - The method is simple, low-cost and environment-friendly.    DETAILED DESCRIPTION - Biofertilizer with rural waste is prepared by taking 40-60 pts. wt. manure, 20-30 pts. wt. mushroom stock, 20-30 pts. wt. crop straw and 0.5-1 pt. wt. bio-fermentation agents, mixing in fermentation tank, fermenting at 50-60 degrees C with humidity of 70-80%, stirring once every 1 hour, transporting in processing equipment and carrying out environmental treatment for 3-5 days. Manure has moisture content of 40-60% and pH value of 6.5-7.5. Crop straw is millet straw, corn straw, soybean straw, sorghum straw and/or rice straw with carbon and nitrogen content ratio of 40-50:1. Bio-fermentation agents comprises beer yeast fermentation broth, Bacillus subtilis bacteria, Lactobacillus delbrueckii bacteria, Streptomyces bacteria at ratio of 2-3:3-4:3-4:4-5. Manure, crop straw and mushrooms stock is prepared by crushing at 50-100 mesh and sieving. Bio-fermentation agents is prepared by mixing 10 g yeast extract medium, 20 g peptone, 20 g glucose and 1000 mL distilled water, and carrying out aerobic fermentation at 28-38 degrees C for 24-48 hours; mixing 15.0 g peptone, 0.50 g beef extract, 20.0 g dextrose, 5.0 g sodium chloride and 1000 mL distilled water, and carrying out aerobic fermentation at 30-36 degrees C for 48-72 hours; mixing 70 mL wort, 10 g beef extract, 5 g yeast extract, 5 g soy protein powder and 1000 mL water, adjusting pH value to 6.5 and carrying out aerobic fermentation at 38-42 degrees C for 48-72 hours; mixing 1 g maltose, 1 g glucose, 1 g sucrose, 3 g starch, 2 g peptone, 10 g beef extract, 5 g yeast extract, 2 g soybean meal and 1000 mL water, adjusting pH value to 6.5 and carrying out aerobic fermentation at 38-42 degrees C for 48-72 hours; and mixing prepared broth.
