Problems solved by technology

But the flexibility of this device itself is not strong enough, and it only utilizes specific sealing device for specific silage ponds, and because silage ponds have different shapes and sizes, when in use, only use it to compact the silage On the surface of the feed, it is also difficult to ensure that the wall of the silage tank can be properly attached to it, and then achieve a completely sealed state, which further affects the silage effect of the silage

Embodiment 1

[0019] A silage sealing method. During the filling process of the silage tank, the silage is formed into a turtle-back shape with a high middle and a low surrounding area, and then the silage is covered with a plastic film, and the plastic film is attached to the wall of the silage tank and turned upward by 30cm, 35cm, 40cm, 45cm or 50cm high, and then inject water to the upper surface of the plastic film from one end to seal, to further ensure that a squeezing force is formed on the wall of the silage tank during sealing, to ensure that the plastic film and the wall of the silage tank are tightly attached to achieve a better seal Effect.

Embodiment 2

[0021] According to the sealing method of the silage in the first embodiment, in order to eliminate the air in the silage tank as much as possible and make it reach an anaerobic state, the water injection sealing can also be performed by filling the water in a plastic film bag, according to the shape of the turtle back. Put down the water-filled plastic film bag at the top, so that the water-filled plastic film bag slides from the top of the turtle's back to the surrounding of the silage tank wall, sticks closely to the silage tank wall, and presses the plastic film; thus ensuring that the air in the silage tank is squeezed out. It can form an effective anaerobic environment, promote the fermentation of lactic acid bacteria, and improve the quality of silage.

Embodiment 3

[0023] According to the sealing method of silage in Embodiment 1 and Embodiment 2, the plastic film used is a high-pressure polyethylene film with a thickness of 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm or 0.2 mm.

Abstract

The present invention relates to the technical field of feed processing, especially to a silage sealing method. Specifically, the silage sealing method includes the following steps: in the process of filling a silage pool with silage, making the silage into a turtle back shape with the middle being high and the surround being low; covering the silage with a plastic thin film, wherein the plastic thin film is pressed tight against the wall of the silage pool and is folded up for 30 to 50 cm high; injecting water to the upper surface of the plastic thin film from one end, and forming a compressing force onto the wall of the silage pool by using the liquidity of water so as to enable the plastic thin film to be tightly pressed against the wall of the silage pool. The water liquidity makes the shape of the plastic thin film to change as the silage changes, so that the plastic thin film covering the surface of the silage can be tightly presses against the silage and the wall of the silage pool to extrude air from the inside of the silage pool, and a good anaerobic environment is accordingly formed. The water liquidity can also automatically fills a gap caused by the silage sinking during a silage maturation process, thereby preventing the phenomenon of poor sealing cause by the sinking of the silage. Therefore, the anaerobic fermentation effects and the quality of the silage can be improved.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a silage sealing method. Background technique [0002] Silage is a kind of feed with rich nutrition, good palatability and long-term preservation; the production of silage provides nutrient-rich and palatable roughage for herbivorous animals in winter. [0003] In the prior art, silage is prepared by anaerobic fermentation of green forage such as forage grass and straw. The principle is to promote the proliferation of lactic acid bacteria in an anaerobic environment, and convert soluble sugar into lactic acid through fermentation, thereby reducing the pH value of silage, effectively curbing the growth of spoilage bacteria, and making the nutrients in silage long-term preservation. Therefore, whether an anaerobic environment can be formed is a decisive factor affecting the quality of silage, that is, in the process of making silage, the degree of sealing will directly aff...
