TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The microorganism strains comprise Bacillus subtilis and Bacillus licheniformis. The content of microorganism in the organic fertilizer is not less than 0.2 million/g. Preferred Method: The anaerobic fermentation in the step (i) is ground piling fermentation method, sealed storehouse type fermentation method or tower type fermenting compartment fermentation method. The ground piling fermentation method comprises: piling up the prepared raw material into the long ridge with a width of 2 m and a height of 1.5 m in a fermenting shed, turning the pile once every 10 day, and composting for 45-60 days. The sealed storehouse type fermentation method comprises: (a) building the fermenting storehouse by cement and brick or assembling the fermenting storehouse by pre-cast slab, where the top is equipped with an openable seal cover, the bottom is equipped with multiple air inlet pipe, air outlet pipe and water outlet pipe, and the formed fermenting storehouse can contain 50-100t of material; and (b) piling the prepared raw material in the fermenting storehouse, and fermenting for 12-15 days to decompose the raw material. The tower type fermenting compartment fermentation method comprises: preparing the sealed fermenting tower by using steel and iron material, providing 6 layers of tower plate in the fermenting tower, automatically turning the plate, inoculating the wet cow dung containing anaerobic bacteria, lifting to the top layer of tower plate, turning once every day through the automatic turning plate to drop on the lower layer, dropping on the bottom tower plate after 6 days, and obtaining the fermenting compost material. The naturally dehydrating in the step (ii) comprises: rapidly dehydrating by the sun light and the natural wind during the sunny day, and turning on the cement ground. The mechanically dehydrating in the step (i) comprises: using the dryer, and controlling the temperature at 102-108 degrees C to dry. The step (iii) comprises adding phosphoric acid solution (3-5 %) to adjust the pH value of the material to 6.8-7.8, during mixing the materials. ACTIVITY - Fertilizer.
