NOVELTY - Method for preparing breeding media and organic fertilizer through edible fungus waste fermentation, involves preparing fermentation liquid of heat-resistant Bacillus and plant beneficial fungi, preparing edible fungus waste and soil particles mixture by crushing edible fungus waste, garden soil and forest soil, mixing and spreading into a thin layer, diluting the obtained fermentation liquids using complex nutritional composition, mixing, spraying on edible fungus waste and soil particles mixture, processing, stacking and fermenting to obtain product.    USE - The method is useful for preparing breeding media and organic fertilizer through edible fungus waste fermentation (claimed).    ADVANTAGE - The method enables to degrade organic substances of edible fungus waste into nutrient substances which are absorbed easily by plant root systems. The temperature of a mixture of the edible fungus waste and soil is raised to more than 50 degrees C under the action of combined metabolic heat generation of microfloras within a short time, to control various soil injection pathogenic bacteria, viruses and worm eggs. The obtained product has functions of changing soil structure, improving soil fertility and preventing diseases. The method is performed simply using easily-available raw materials, and prepares product which increases survival rate of seedlings without repeated application of bactericides and insecticides, and reduces pollution of toxic pesticides to the environment.    DETAILED DESCRIPTION - Method for preparing breeding media and organic fertilizer through edible fungus waste fermentation, involves inoculating heat-resistant Bacillus in a culture medium in sterilized flask, culturing at 48-51 degrees C for 15-25 hours under condition of shaking at 100-160 revolutions/minute (rpm), cooling to 50 degrees C, obtaining heat-resistant Bacillus seed liquid, inoculating 1-3% heat-resistant Bacillus seed liquid into a fermentation medium contained in the fermentor, culturing at 50-53 degrees C for 24-48 hours, cooling to room temperature, obtaining preparing fermentation liquid of heat-resistant Bacillus, inoculating plant beneficial fungi in a fungal culture liquid formulation in sterilized flask, culturing at 24-30 degrees C for 72-96 hours under condition of shaking at 120-200 rpm, cooling to 28 degrees C, obtaining plant beneficial fungi seed liquid, inoculating 3-6% plant beneficial fungi seed liquid into a fermentation medium contained in the fermentor, culturing at 26-32 degrees C for 96-120 hours, cooling to room temperature, obtaining preparing fermentation liquid of plant beneficial fungi, preparing complex nutritional composition by adding 1-3 %mass sugar, 0.2-0.5 %mass phosphate, 0.1-0.3 %mass potash, calcium hydroxide or potassium hydroxide (reduced quantity) to adjust pH to 9-10, in water, preparing edible fungus waste and soil particles mixture by crushing edible fungus waste into particle with size of 2-6 mm, crushing garden soil and forest soil, sieving to obtain soil particle with size of less than 6 mm, mixing the crushed edible fungus waste and soil particles in a ratio of (1.5-3):1 at more than 50 degrees C, spreading into a thin layer and obtaining product, diluting the obtained fermentation liquids using complex nutritional composition to obtain suspensions, mixing uniformly, spraying on edible fungus waste and soil particles mixture and mixing in a ratio of 1:(0.5-1), regulating moisture to 50-60%, stacking and fermenting to obtain product. The heat-resistant Bacillus is chosen from B.subtilis, B.licheniformis, B.natto, B.laterosporus, B.cereus, Paenibacillus polymyxa, B.stearothermophilus and their combinations. The plant beneficial fungi is chosen from Trichoderma, Aspergillus niger, Mucor, Rhizopus, Absidia, Neurospora crassa and their combination.
