Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer preparation, in particular to a preparation device for concentrated organic liquid fertilizer. Background Art

[0002] The organic residues and waste liquid after biogas fermentation are collectively referred to as biogas fermentation residues, which are composed of solid and liquid parts. The middle of the biogas tank is liquid, usually called biogas liquid, and the bottom is muddy sediment, called biogas residue. In biogas tanks without stirring devices, the phenomenon of solid and liquid stratification is very common, which has a certain impact on biogas production and biogas fertilizer output; biogas liquid not only contains rich macronutrients such as nitrogen, phosphorus, potassium and trace nutrients such as zinc, but also contains 17 kinds of amino acids and active enzymes. Therefore, biogas liquid has strong fast-acting nutritional capacity and high nutrient utilization rate. It is a multi-element fast-acting compound fertilizer that can be quickly absorbed and utilized by animals and crops. Therefore, biogas liquid and biogas residue are sanitary fertilizers with very few pathogens. They are often used for seed soaking and foliar fertilization in production to achieve the effect of disease prevention and pest control.
