Problems solved by technology

Developed countries in the world have basically formed a fertilization system of "straw + barn manure + chemical fertilizer". my country has completely banned the burning of straw and returning it to the field. Many straws are directly rotted on the field as base fertilizer, or straw is crushed as auxiliary materials for the production of organic fertilizers, but the overall utilization rate is low.
In recent years, the demand for silage / yellow silage in my country has been increasing. At present, many of them still continue to use the original natural silage. The problems of moldy silage and secondary fermentation are serious. Some cattle farms even feed silage covered with mold spores. There are countless cases of death of animal storage caused by feeding moldy and deteriorating bluegrass

Embodiment 1

[0017] The number of effective viable bacteria after the fermentation of the microbial bacterial agent is 5.6×10 9 CFU / mL, including 30 parts of Lactobacillus plantarum, 20 parts of Bacillus coagulans, 30 parts of Lactobacillus rhamnosus and 20 parts of Lactobacillus Brucella, in parts by weight.

[0018] The crop stalks used for silage are whole corn stalks, crush the crop stalks to 2-3cm, control the water content of the material to 65%, the amount of material per ton of silage / yellow silage is 250mL, and the compound microbial agent is mixed with 2 kg of water per 200mL , sprayed into the silage / yellow silage material with a sprayer, tied tightly with a baling and coating machine, and the material moisture was fermented at 33-35° C. for 26 days to obtain silage.

Embodiment 2

[0020] The number of effective viable bacteria after the fermentation of the microbial bacterial agent is 8.5×10 9 CFU / mL, including 30 parts of Lactobacillus plantarum, 30 parts of Bacillus coagulans, 20 parts of Lactobacillus rhamnosus and 20 parts of Lactobacillus Brucella, in parts by weight.

[0021] The crop stalks used for silage are the whole corn stalks. Crush the crop stalks to 2-3cm, control the water content of the material to 60%, the amount of material per ton of silage / yellow silage is 300mL, and the compound microbial agent is mixed with 2 kg of water per 200mL , sprayed into the silage / yellow silage material with a sprayer, tied tightly with a baling and coating machine, and the material moisture was fermented at 30-35° C. for 28 days to obtain silage.

Embodiment 3

[0023] The number of effective viable bacteria after the fermentation of the microbial bacterial agent is 7.6×10 9 CFU / mL, including 25 parts of Lactobacillus plantarum, 30 parts of Bacillus coagulans, 20 parts of Lactobacillus rhamnosus and 25 parts of Lactobacillus Brucella, in parts by weight.

[0024] The crop straw used for silage is wheat straw, and the crop straw is crushed to 2-3cm, and the water content of the material is controlled to 60%. The sprayer is sprayed into the silage / yellow silage material, and it is tightly bound with a baling and wrapping machine. The moisture content of the material is fermented at 28-33°C for 32 days to obtain silage.

Abstract

The invention relates to the field of biology, in particular to a composite microbial treatment agent for fermenting silage and hay silages and a preparation method thereof. The composite microbial treatment agent is characterized by being prepared from, by weight, 10-30 parts of lactobacillus plantarum, 15-30 parts of bacillus coagulans, 15-30 of lactobacillus rhamnosus and 10-30 parts of lactobacillus buchneri, and the effective viable cell count of the microbial treatment agent is 1.0 to 9.9*109 CFU / mL. Compared with the prior art, the method uses the bacillus coagulans, the lactobacillus plantarum, the lactobacillus rhamnosus and the lactobacillus buchneri composite microbial agent for silage / hay silage fermentation, and can effectively inhibit the growth of hybrid bacteria, after fermentation, the pH can be increased to 3.7-4.1, the total organic acid content such as acetic acid, propionic acid and butyric acid is increased, the ammonia nitrogen content is reduced, a finished product has an aromatic fruit flavor, thereby reducing a taste beneficial to improving the feeds, and the nutritional value of the feeds is improved.

Description

technical field [0001] The invention relates to the field of biology, in particular to a compound microbial treatment agent for fermenting silage and yellow silage and a preparation method thereof. Background technique [0002] As a large agricultural country, my country produces a large amount of crop straw every year, such as wheat, corn, beans and sorghum, and only a small amount of these are used as silage / yellow silage as roughage for animal production. Developed countries in the world have basically formed a fertilization system of "straw + barn manure + chemical fertilizer". my country has completely banned the burning of straw and returning it to the field. Many straws are directly rotted in the field as base fertilizers, or crushed as auxiliary materials for the production of organic fertilizers, but the overall utilization rate is low. In recent years, the demand for silage / yellow silage in my country has been increasing. At present, many of them still continue to ...
