Problems solved by technology

According to statistics, the amount of chemical fertilizer per unit area in my country has reached 1.6 times the world's average amount, and the application of chemical nitrogen fertilizer accounts for 1 / 4 of the world's amount. Such a large amount of application not only wastes resources, but also increases agricultural costs. Destroy the soil structure and pollute the environment of rivers and lakes

Embodiment 1

[0069] Preparation of solid waste organic fertilizer in Xiaolan Industrial Park:

[0070] Stirring: Put the dregs of traditional Chinese medicine, western medicine and food into the mixer at the ratio of 40%, 35% and 25% respectively, and stir evenly.

[0071] Fermentation: Send the uniformly stirred materials into the fermentation tank of the closed fermentation workshop with a loading vehicle. The height of the material is 0.8m to 1.2m. The electric track rotary tillage turner turns the pile every two days, and turns the pile once a day when the temperature is greater than 60°C. Increase the ventilation when turning over, and the gas produced by fermentation is introduced into the biofilter with the induced draft fan to absorb and biodegrade until it is odorless and then discharged. After fermentation until the temperature begins to drop, the water content is detected, and when the water content is less than or equal to 30%, the fermentation is stopped.
