The invention relates to a method for producing an organic fertilizer by using water hyacinth as a raw material and mixed composting fermentation. The method comprises the following steps of: crushing and dehydrating the water hyacinth salvaged by a salvage boat, and adding the fermented animal dung into the crushed and dehydrated water hyacinth; after uniform mixing, feeding the mixture into a groove-shaped fermentation tank to perform composting fermentation; when the temperature of the materials is raised to between 40 and 70 DEG C, performing turning oxygen supply by using a turning device and performing further dehydration; when the temperature is raised to between 60 and 70 DEG C, turning the mixture twice every day; and after the fermentation is finished, obtaining an organic fertilizer product by direct packing or crushing and packing or extrusion and granulation according to different purposes. The method is simple and feasible, can realize resource utilization of the water hyacinth, does not produce secondary pollution, and provides the safe and pollution-free fertilizer for agricultural production when solving the pollution problem. |
