Silage sealing method

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...

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
