Problems solved by technology

One is that this kind of packaging is easy to be damaged. Once the stretch film is damaged, yeast and mold will multiply, causing the silage to deteriorate and become moldy
The second is that it is easy to cause uneven moisture content among different bales, resulting in differences in fermentation quality, which brings difficulties to feed nutrition design, and it is difficult to accurately grasp the appropriate supply amount

Embodiment 1

[0022] 1. Clean up the storage cellar: Choose a silage cellar with a depth of about 4m. Before the corn is harvested, clean the silage cellar to remove the residual bacteria in the silo cellar to prevent it from continuing to reproduce and pollute the new silage raw materials; after cleaning, clean the silage cellar. Lay clean plastic sheets on both sides of the silo to isolate the interior of the silo from the outside environment, avoiding the invasion of bacteria and polluting the silo;

[0023] 2. Pressure cellar: Harvest and crush the whole plant corn. The length of the crushed corn raw material is 2.2cm. The crushed whole plant corn, silage additives and starter are added layer by layer from the bottom of the cellar; the specific pressure storage of each layer of silage The method is as follows: add the harvested and crushed whole plant corn into the silage cellar, and then add the starter while compacting, add 5 grams of starter per ton of silage, and add 10 grams of sila...

Abstract

The invention relates to a method for preparing full-plant corn silage by cellar pressing, which comprises the steps of cleaning a storage cellar, pressing the cellar, sealing the cellar and fermenting. The pressure storage of each silage layer adopts specific parameters, each ton of silage is added with 2-6 grams of a fermenting agent and 8-10 grams of a silage additive; after compaction, the thickness of each silage layer is 10cm-20cm, and the density is 700kg / m <3>;; The temperature of the silage cellar is selected to be in a normal temperature environment; the cellar-pressing silage is completed within 10 hours after the silage raw materials are harvested; wherein the water content of the silage raw material is ensured to be between 62% and 74% when harvesting; lactobacillus plantarumand pediococcus lactis are selected as the silage fermenting agent, and the dosage ratio of the lactobacillus plantarum and the pediococcus lactis is 2: 1; the silage additive is selected from cellulase, xylanase and calcium sodium silicate hydrate, and the dosage ratio of the cellulase to the xylanase to the calcium silicate hydrate is 5: 3: 2; according to the invention, the prepared silage hashigher water content, and the silage is fresh, tender and juicy; The content of soluble sugar and the consumption rate of crude protein in the silage are reduced to a lower degree, and nutrients in the silage are better retained; the pH value is lower, thereby being more beneficial to long-term stable storage of the silage.

Description

technical field [0001] The application relates to the field of feed processing, in particular to a method for preparing whole-plant corn silage under pressure. Background technique [0002] Silage refers to the method of preserving green and juicy green fodder (fresh corn stalks, grass, etc.) under anaerobic conditions (through microbial fermentation). People have used the method of silage to preserve fodder for thousands of years. The word "silo" is derived from the Greek word "siros", which means a pit or hole in the ground. Ancient paintings unearthed in Egypt show that the ancient Egyptians were familiar with and used silage technology as early as 1000-1500 BC. Silage belongs to the third largest category in the feed classification system. Silage has been widely used in animal husbandry production in various countries in the world. It is an important green and juicy feed for feeding ruminant livestock (cows, beef cattle, milk sheep, mutton sheep, deer, horses, donkeys,...
