Embodiment 1

[0025] A method for fermenting straw silage, the specific steps are as follows:

[0026] 1) Weigh 30 parts of straw and 20 parts of forage grass according to weight parts, cut into lengths of 2 cm, add 10 parts of forage additives, mix and stir, lay flat on the ground for drying, and dry until the water content is 50% by weight to make silage material;

[0027] 2) Put the silage into the fermentation tank, lay a layer of waterproof substrate with a thickness of 5cm on the bottom, then pile the silage on top, spray 1 part of forage treatment agent for every 5cm of accumulation;

[0028] 3) Add the mixed bacterial solution to the silage, and the inoculation amount is 50ml of the mixed bacterial solution per kg of forage;

[0029] 4) After mechanically compacting the silage, cover it with a layer of plastic film with a thickness of 1 cm, and then cover it with 20 cm of soil, and carry out sealed fermentation. The temperature in the fermentation tank is 15 ° C, and the fermentati...

Embodiment 2

[0040] A method for fermenting straw silage, the specific steps are as follows:

[0041] 1) Weigh 35 parts of straw and 25 parts of forage grass according to weight parts, cut into lengths of 2 cm, add 15 parts of forage additives, mix and stir, lay flat on the ground for drying, and dry until the water content is 55% by weight to make silage material;

[0042] 2) Put the silage into the fermentation tank, lay a layer of waterproof substrate with a thickness of 7cm on the bottom, then pile the silage on top, and spray 1 part of forage treatment agent for every 7cm of accumulation;

[0043] 3) Add the mixed bacterial solution to the silage, and the inoculum amount is 70ml of the mixed bacterial solution per kg of forage;

[0044] 4) After mechanically compacting the silage, cover it with a layer of plastic film with a thickness of 1 cm, and then cover it with 25 cm of soil, and carry out sealed fermentation. The temperature in the fermentation tank is 17 ° C, and the fermentat...

Embodiment 3

[0055] A method for fermenting straw silage, the specific steps are as follows:

[0056] 1) Weigh 40 parts of straw and 30 parts of forage grass according to weight parts, cut into lengths of 3 cm, add 20 parts of forage additives, mix and stir, lay flat on the ground for drying, and dry until the water content is 60% by weight to make silage material;

[0057] 2) Put the silage into the fermentation tank, lay a layer of waterproof substrate with a thickness of 10cm on the bottom, then stack the silage on top, and spray 2 parts of forage treatment agent for every 10cm of accumulation;

[0058] 3) Add the mixed bacterial solution to the silage, and the inoculation amount is 100ml of the mixed bacterial solution per kg of forage;

[0059] 4) After mechanically compacting the silage, cover it with a layer of plastic film with a thickness of 2 cm, and then cover it with soil for 30 cm, and carry out sealed fermentation. The temperature in the fermentation tank is 20 ° C, and the ...

Abstract

The invention discloses a straw silage forage fermentation method. The method includes the following specific steps: 1) mixing straws and forage grass, chopping, adding a forage additive for drying tomake silage; 2) stacking the silage in a fermentation tank and spraying a forage treatment agent; 3) inoculating a certain amount of mixed bacterial liquid on the silage; 4) compacting the silage, covering the silage with a film, and then covering the film with the soil for sealed fermentation for 10-20d. The silage prepared by the fermentation method has the advantages of being simple and efficient in preparation method, rich in nutrition and easy to digest, beneficial to increasing food intake of poultry and promoting the growth.

Description

technical field [0001] The invention belongs to the technical field of forage processing, and in particular relates to a method for fermenting straw silage forage. Background technique [0002] Silage refers to the compaction and sealing of fresh plant varieties, so that the stored green fodder is isolated from the outside air, resulting in internal hypoxia and anaerobic fermentation, thereby producing organic acids, which can keep the fresh silage for a long time, and can reduce the A storage technique or method in which nutrient loss is beneficial to animal digestion and absorption. [0003] Silage is prepared by fermentation with lactic acid bacteria. It has the characteristics of rich nutrition and easy digestion. After fermentation, it has an aromatic and sour taste, which can stimulate the appetite of poultry, increase food intake, and promote the growth of poultry. The currently prepared silage forage will have poor stability, easy corruption, and large loss of dry m...
