Technical Field

The present invention relates to the field of biogas slurry application, in particular to a device for injecting and applying livestock farm manure sewage to farmland after fermentation.

Background

At present, manure sewage produced by livestock farms cannot be directly discharged. In order to make full use of and recycle the waste components in the manure sewage, the manure sewage is generally fermented into biogas slurry, and then the biogas slurry is applied to farmland as a fertilizer, which not only avoids environmental pollution, but also saves the cost of fertilization. The actual effect is very obvious. However, existing fertilization methods are generally implemented by flooding or spraying the biogas slurry, which causes serious volatilization of ammonia in the biogas slurry, and also produces a large amount of greenhouse gases that diffuse into the surrounding environment. A strong smell and a large loss of nitrogen are caused, and the fertilizer efficiency of the biogas slurry is greatly reduced. Therefore, a fertilizer applying device that can ensure fertilizer efficiency and reduce nitrogen volatilization is needed to improve the utilization efficiency of the biogas slurry.
