NOVELTY - Producing organic fertilizer using plant straw aerobic fermentation involves taking plant straw material (60-65 wt.%) having water content of 30-35% to obtain A material; adding edible fungi slag (20-22%), crushing and adding calcium-magnesium phosphate (5%) to obtain material B; mixing cellulose decomposing microbial agent (1%) with cake cypress (14-16) to form material C; adding material A, B and C and water to fermentation tank, carrying out fermenting in aerobic fermentation for 7-10 days, at 50-65 degrees C, granulating, drying, sieving to obtain the finished product.    USE - For producing organic fertilizer (claimed).    ADVANTAGE - The method prepares fertilizer that has long fertilizer effect, improves soil, and promotes growth of various plants.    DETAILED DESCRIPTION - Producing organic fertilizer using plant straw aerobic fermentation involves taking plant straw material (60-65 wt.%) having water content of 30-35% to obtain A material; adding edible fungi slag (20-22%), crushing and adding calcium-magnesium phosphate (5%) to obtain material B; mixing cellulose decomposing microbial agent (1%) with cake cypress (14-16) to form material C; passing material A, B and C through a stirrer and stirring uniformly, adding an amount of water, to make the water content reach 55-60%, adding it to fermentation tank, carrying out fermenting in aerobic fermentation for 7-10 days, at 50-65 degrees C, using neural lock turning mechanism turning for 3-4 times, when the stack temperature is stable at 30 degrees C, ending the fermentation to obtain the finished product by granulating, drying, sieving, till the water content of the finished product fertilizer is controlled at 15-20%. The edible fungi slag is straw mushroom, mushroom, mushroom, needle mushroom and edible fungi. The calcium magnesium phosphate fertilizer is a late effect mineral inorganic fertilizer. The cellulose decomposition bacteria selected from bacillus subtilis, cellulomonas fiber, Bacillus Lichenifpus, Cellulomonas cartae, Trichoderma viride.
