NOVELTY - Bioorganic fertilizer comprises agricultural and forestry waste, organic fertilizer base material, quicklime, fermentation broth and bacteria liquid, and the agricultural and forestry waste contains at least 70% of the mushroom waste material, the bacterial fermentation broth includes Bacillus amyloliquefaciens, Bacillus subtilis, Lactobacillus, Actinomycetes and yeast, and fermentation broth containing live bacteria. Functional bacteria includes nitrogen-fixing bacteria, phosphorus solubilizing bacteria, and potassium solubilizing bacteria solution.    USE - Used as bioorganic fertilizer.    DETAILED DESCRIPTION - Bioorganic fertilizer comprises 100 pts. wt. agricultural and forestry waste, 20-35 pts. wt. organic fertilizer base material, 3-5 pts. wt. quicklime, 0.01-0.02 pts. wt. fermentation broth and 0.01-0.02 pts. wt. bacterial liquid, where the agricultural and forestry waste contains at least 70% mushroom waste material; the bacterial fermentation broth includes 1 pts. wt. Bacillus amyloliquefaciens, 0.6-0.8 pts. wt. Bacillus subtilis, 0.9-1 pts. wt. Lactobacillus, 0.5-6 pts. wt. actinomycetes and 0.8-1 pts. wt. yeast, and less than or equal to 6.5-8x 109 cells/ml live bacteria containing fermentation broth. The functional bacteria includes 1 pts. wt. nitrogen-fixing bacteria, 0.7-1.2 pts. wt. phosphorus solubilizing bacteria, and 0.7-1.2 pts. wt. potassium solubilizing bacterial solution; the amount of live bacteria in broth is 2.5-3.5x 109 cells/ml. An INDEPENDENT CLAIM is also included for preparing bioorganic fertilizer comprising (i) crushing the agricultural and forestry waste contains at least 70% of the mushroom waste material, and stacking to form a pile, and carrying out natural fermentation by watering and covering the plastic film on the pile for 2-3 weeks; (ii) covering with quicklime on the top of the heap of waste material before the end of the fermentation till the end of the fermentation; (iii) adding, and mixing 1/3 to 1/4 waste material stack with the organic fertilizer base, 0.01-0.02 wt.% of stockpile in the organic fertilizer fermentation broth, and watering, stacking and covering with plastic film and fermenting for 2-3 weeks; (iv) inoculating functional bacteria in composting manure heap and spraying 0.01-0.02 wt.% stockpile to the functional bacteria broth, and mixing, then stacking for 4-7 days to obtain biological organic fertilizer, where in the step (iii) and step (i) the stockpile moisture content is 50-60%, during the fermentation process, turning once for every 5-7 days, and inoculating functional bacterial including nitrogen-fixing bacteria, phosphorus solubilizing bacteria, and potassium solubilizing bacteria solution.
