Problems solved by technology

Up to now, commonly used food waste treatment technologies at home and abroad include incineration, sanitary landfill, ecological fertilizer, anaerobic digestion, aerobic composting and vermicomposting, etc., and foreign countries have formed a mature environmental protection industry for food waste resource treatment , while the country is still in its infancy, and in the resource treatment of food waste, there are usually defects of low resource utilization efficiency and unsatisfactory economic benefits
When incinerated, food waste not only has low thermal efficiency, but also produces toxins that pollute the environment

Abstract

The invention discloses an organic fertilizer and a preparation method thereof. The preparation method comprises the following steps of (1) adding auxiliary materials into food wastes with water content of 60 to 80 wt% until the water content is reduced to 50 to 59 wt%, so as to obtain a mixture; (2) adding a fermenting bacterial agent into the mixture, and performing fermentation. The organic fertilizer has the advantages that the food wastes are fermented to obtain the organic fertilizer, so as to maximize the effective cyclic utilization of nutritional substances when the food wastes are used for producing the fertilizer, avoid the waste of resources, and produce the high economic benefits; when the organic fertilizer is applied, the excessive accumulation of nitrogen and phosphor in soil is avoided, the content of quick-effect potassium in the soil is obviously increased, the activity of the soil is improved, the seed germinating and root germinating are promoted to supply nutrients and active substances for the crop, and the intensity of photosynthesis is enhanced; the necessary multiple nutritional elements required by the crop can be continuously supplied for a long time inthe continuous mineralization process in the soil, the fertility of the soil is improved, the physical and chemical properties of the soil are improved, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an organic fertilizer and a preparation method thereof. Background technique [0002] From the period of the founding of the People's Republic of China to the 1980s, the proportion of chemical fertilizer application in the total amount of fertilization in agricultural production increased from 10% to 50%, and now it has reached 90%. As the main means of agricultural production, chemical fertilizers play a huge role in increasing production in the process of agricultural development. At the same time, there are also problems such as increasing the input of agricultural resources, wasting agricultural resources, reducing fertilizer use efficiency, deteriorating soil physical and chemical properties, and inhibiting the growth and reproduction of soil microorganisms. , reducing the number of soil microorganisms, reducing soil microbial biomass carbon, reducing soil en...
