NOVELTY - A biological fertilizer comprises (parts by weight): waste vegetables (90-110), straw (45-55), livestock (18-22) and poultry manure, rice bran (6-10), urea (1.7-2), and ammonium sulfate (1.7-2); and the quantity of the complex lively bacterial preparation is 0.08-0.12 percent of the total mass, the quantity of the compound enzyme is 0.008-0.010 percent of the total mass.    USE - As biological fertilizer (claimed).    ADVANTAGE - The method saves energy, has no pollution, investment is low, cost is low and fertilizer effect is high. The biological fertilizer can effectively use the agricultural waste, at the same time without straw by processing, save the acid and alkali resistance, reduces the environment pollution, effectively degrade the crude fiber, improve the contents of nitrogen and cheap inorganic N, is transformed into value of organic N source by microbial fermentation, increase the amino acid, polypeptide, vitamin, physiologically active substance and unknown growth factor, increases the nutritional value; save production equipment, saves energy, simplifies the production procedure, reduces the investment and production cost, where the invention viable cell number is up to 0.2-0.8 hundred million/g.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the biological fertilizer, involving: grinding the waste vegetables into size of less than 10 millimeters, grinding the straw into size of less than 10 millimeters; adding straw (45-55 mass parts), livestock and poultry manure (18-22 mass parts), rice bran (6-10 mass parts), urea (1.7-2 mass parts), and ammonium sulfate (1.7-2 mass parts) into waste vegetables (90-110 mass parts) for mixing, adjusting the water content of the mixed material (50-65 percent), adding complex lively bacterial preparation (0.08-0.12 percent) and compound enzyme (0.008-0.010 percent) into the mixture according to the mixture mass, completely and uniformly stirring the mixture, controlling the water content of the ferment material (50-65 percent), adjusting the pH value of 6.2-7.8 by 1% limewater, processing the aerobic fermentation for 10-20 days, getting the biological fertilizer product.
