Embodiment 1

[0023] Step 1: The original kitchen materials are sorted, rinsed and crushed into a slurry, and then enter the Hanbo drying and chemical all-in-one machine (2 tons of volume), the mixing system starts to stir the materials, and the heating system starts to heat up. When the temperature of the material rises to 55°C, the heating system stops working, and the residual heat and the microorganisms in it work to generate heat to make the temperature of the material continue to rise. When the temperature of the material rises to about 60°C, the material outlet door of the all-in-one machine can be opened to allow The mixing system works to push the material from the middle to the door and then into the belt conveyor. The belt conveyor continues to convey the materials to the aging room, and the discharge time is 40-50 minutes. The material coming out enters the aging room, the aging room is 1.5 meters high, 2 meters wide, and 5 meters long. At this time, the temperature of the mater...

Abstract

The invention relates to a method for preparing an organic fertilizer for rice from kitchen waste and sawdust through combined composting, which specifically comprises the following steps of: sorting,leaching and drying original kitchen materials into granular kitchen raw materials with the water content of 10-30%, adding sawdust with the water content of lower than 10% and the particle size of 1-3cm into the granular kitchen raw materials, and adding a VT microbial agent into each cubic meter of compost, uniformly stirring and mixing, fermenting by adopting a strip-chopping type composting aerobic process, dynamically monitoring the temperature of the compost in the fermentation process, and stirring and turning the compost when the temperature rises to 65 DEG C or above, so as to reducethe temperature to 60 DEG C or below; maintaining the temperature of the high-temperature stage at 55-65 DEG C for 5-7 days, and quickly fermenting the strains in the high-temperature stage; and thenturning and stirring once every five days until the temperature of the pile body is reduced to the ambient temperature. The organic matter content of the fertilizer prepared through the method reaches 90% or above, the moisture content is lower than 25%, the nitrogen content is higher than 5%, and when the fertilizer is applied to a paddy field, the yield, taste and aroma of rice can be remarkably improved, and the yield is averagely improved by 20% or above.

Description

technical field [0001] The invention relates to the field of resource utilization of agricultural environmental waste, in particular to a method for preparing organic fertilizer for rice by combined composting of kitchen waste and sawdust. Background technique [0002] With the rapid development of urbanization, more and more urban food waste and wood waste are produced. In recent years, the output of food waste in my country has shown a steady upward trend, and the average daily production of food waste in major cities is more than 1,000 tons. . Food waste is rich in organic matter, high in water content, low in combustion calorific value, high in oil and salt, contains germs and pathogenic microorganisms, and is perishable. During transportation and treatment, it not only produces a large amount of toxins, but also pollutes water bodies and the atmosphere. The resulting secondary pollution has brought great harm to the environment. Similarly, due to the development of urb...
