Embodiment 1

[0052] A silage additive using peracidified biogas slurry as the main raw material, comprising the following components in parts by weight:

[0053] 10 parts of peracidified biogas slurry, 10 parts of tap water, pectinase (enzyme activity: 5.0×10 3 IU / g) 0.05 parts, xylanase (enzyme activity: 1.0×10 4 IU / g) 0.05 parts, catalase (enzyme activity: 1.0×10 4 IU / g) 0.02 parts.

[0054] The preparation method of described silage additive, the steps are as follows:

[0055] (1) For the acquisition of overacidified biogas slurry, choose a continuous anaerobic fermentation device with vegetable waste as the main raw material. The biogas production suddenly drops by 80%, the pH drops rapidly to 5.0, and cannot be recovered within 2 days. When the concentration of propionic acid reaches 3000mg / L and the concentration of acetic acid reaches 6000mg / L, the biogas slurry is quickly discharged for use. This is the over-acidified biogas slurry crude liquid;

Embodiment 2

[0062] A silage additive using peracidified biogas slurry as the main raw material, comprising the following components in parts by weight:

[0063] 10 parts of peracidified biogas slurry, 10 parts of tap water, pectinase (enzyme activity: 5.0×10 3 IU / g) 0.04 parts, xylanase (enzyme activity: 1.0×10 4 IU / g) 0.04 parts, catalase (enzyme activity: 1.0×10 4 IU / g) 0.01 parts.

[0064] The preparation method of described silage additive, the steps are as follows:

[0065] (1) For the acquisition of peracidified biogas slurry, choose a batch-type anaerobic fermentation device with vegetable waste as the main raw material. After charging, pay close attention to the fermentation indicators such as biogas production, pH, and organic acid content. In the case of a sudden drop of 90%, a rapid drop of pH to 5.5, and failure to recover within 2 days, and a concentration of propionic acid reaching 2000mg / L and acetic acid reaching 4000mg / L, the biogas slurry is quickly discharged for use...

Embodiment 3

[0072] A silage additive using peracidified biogas slurry as the main raw material, comprising the following components in parts by weight:

[0073] 10 parts of peracidified biogas slurry, 20 parts of tap water, pectinase (enzyme activity: 5.0×10 3 IU / g) 0.06 parts, xylanase (enzyme activity: 1.0×10 4 IU / g) 0.06 parts, catalase (enzyme activity: 1.0×10 4 IU / g) 0.03 parts.

[0074] The preparation method of described silage additive, the steps are as follows:

[0075] (1) For the acquisition of peracidified biogas slurry, select a continuous anaerobic fermentation device with kitchen waste as the main raw material, and pay close attention to the fermentation indicators such as biogas production, pH, organic acid content, etc. In the case of a sudden drop of 95%, a rapid drop of pH to 4.8, and failure to recover within 2 days, and the concentration of propionic acid reaches 3600mg / L, and the concentration of acetic acid reaches 7500mg / L, the biogas slurry is quickly discharge...

Abstract

The invention relates to a silage additive with peracidified biogas slurry as the main raw material, its preparation method and application. The composition includes the following components in parts by weight: 10 parts of peracidified biogas slurry, 10-20 parts of tap water, 0.04-0.06 parts of pectinase, 0.04-0.06 part of xylanase, and 0.01-0.03 part of catalase. The invention uses peracidified biogas slurry produced by failed anaerobic biogas fermentation as the main raw material, and adds enzymes such as pectinase, xylanase and catalase to prepare the silage additive through aeration, ultraviolet irradiation and other treatment steps. The present invention makes full use of propionic acid and acetic acid rich in overacidified biogas slurry, has a good effect in the silage of pasture grass and crop straw, has simple preparation process, low product cost and outstanding effect, and has application prospects in the field of agricultural waste recycling broad.

Description

Technical field: [0001] The invention relates to a silage additive using peracidified biogas slurry as a main raw material, a preparation method and application thereof, and belongs to the technical fields of agricultural biotechnology and rural environmental protection. Background technique: [0002] With the rapid development of my country's animal husbandry and breeding industry, the market demand for various coarse and concentrated feeds is increasing. In the feeding of herbivores such as cattle and sheep, roughage such as grass and straw plays an important role. However, due to factors such as seasons, most areas in my country lack the supply of fresh pasture and straw feed in winter and spring, and often can only be replaced by hay and dry straw, which greatly reduces the nutrition, flavor, palatability and other indicators of the feed. Silage is a long-established and very effective way to preserve fresh plant materials. Traditional silage does not add other ingredie...
