NOVELTY - A microbiological organic fertilizer comprises following components: 5-40 pts. wt. of layered silicate, 0.1-0.25 pts. wt. of Bacillus megaterium, 0.1-0.25 pts. wt. of jelly like Bacillus, 0.1-0.25 pts. wt. of Bacillus subtilis, and 235-510 pts. wt. of fermented agricultural waste containing nitrogen element, potassium element and phosphorus element, where the weight ratio of nitrogen element, the potassium element and phosphorus element in the fertilizer is 6-18%.    USE - As microbiological organic fertilizer (claimed) for increasing yield of crops.    ADVANTAGE - The fertilizer does not cause ecological and environmental problems, improves crop nutrition level, improves product quality, and has beneficial effects on human and animal health. The fertilizer has improved biological activity, provides health care effect and environmental protection, reduces use of pesticide, has improved fertilizing efficiency, has reduced production cost, improves ecological environment, exhibits production safety and provides high quality products, protects human health, has reduced investment cost, allows large scale production of crops, provides crops of good quality, and achieves pollution-free agricultural production goals.    DETAILED DESCRIPTION - A microbiological organic fertilizer comprises following components: 5-40 pts. wt. of layered silicate, 0.1-0.25 pts. wt. of Bacillus megaterium, 0.1-0.25 pts. wt. of jelly like Bacillus, 0.1-0.25 pts. wt. of Bacillus subtilis, and 235-510 pts. wt. of fermented agricultural waste containing nitrogen element, potassium element and phosphorus element, where the weight ratio of nitrogen element, the potassium element and phosphorus element in the fertilizer is 6-18%. The fertilizer is prepared by adding the microbial inoculum in animal excrement according to the need of microbial enzyme, selecting proper inorganic and organic inducer according to proportion, crushing, homogenizing, inducing microbial fermentation of rotten agricultural industrial waste, fermenting, material compatibility and modulating, where the method includes: treating animal excreta by using mechanical production line high temperature-high pressure mixing and fermentation drying method or fully-automatic production line high temperature rapid fermentation drying method or drying method with a dehydration process, where fresh fecal water content is reduced to 60% to 65% to form desired dehydration treatment specification; fully mixing the animal excrement and decomposed organic substance, after mixing, taking 1500 g to 2000 g, then adding activated fermentation microbial inoculum, adding 80-120 g inoculants in a culture medium, adjusting pH of culture at pH 5.6-6.2, fermenting for 30 days, turning over for 2-3 times, after fermenting, adding 600-1000 g of arbuscular mycorrhizal inoculants according to mass%, where the arbuscular mycorrhizal inoculants are Moses Glomus like or balloon-like, setting balloon mold and Moses Glomus surface and three arbuscular mycorrhizal fungus to a mass ratio (wt./wt.) of 2:2:1, setting Bacillus megaterium, jelly like Bacillus and Bacillus subtilis and pea root nodule (Rhizobium leguminosarum), Aspergillus niger, Aspergillus oryzae, and specific corrosion medium (Humicola insolens) fermentation liquid volume ratio at 1:0.8:1.2:1.4:0.6:0.8:1.2, adding to the inoculum, 1-5 parts of fermentation liquid mixture and 95-99 pts. wt. of animal excrement and decomposed organic substance, adjusting the water content to 60 to 70 wt.% and the pH value at 6.5-7.5, fully and uniformly mixing, high piling through 0.4-0.6 mm strip-shaped material stack, hemp or grass curtain cover, controlling material stack temperature at 25-30 degrees C, turning for one time, fermenting culture for 30 days, stopping fermentation when water content is 20 to 22 wt.%, then adding 5% to 10% mushroom residue, 6% to 10% of straw ash and 600-1000 g arbuscular mycorrhizal inoculant to form the microbiological organic fertilizer.
