Silage refers to the process of feed processing with special aromas and nutrients by shortening fresh pastures, corn stalks, vines, etc. into silages, isolating the air, and fermenting microorganisms (lactic acid bacteria). Whole plant corn, corn stover, imperial bamboo grass, grass (rye grass), root tuber (radish, kohlrabi), vines (potato vines) and other raw materials, high sugar content, as long as the adjustment of water, easy to silage success.
To make high-quality silage, we must grasp several points: 1, anaerobic environment. Lactic acid bacteria fermentation requires an anaerobic environment. Compaction, quick loading, and sealing can create an anaerobic environment quickly and lastingly; 2. Sufficient sugar (1—1.5%). Lactic acid bacteria need sugar, green feed containing less sugar, difficult to silage, need to add a certain proportion of sugar-rich feed such as corn flour, sweet potato silk, etc.; 3, suitable for water (60-75%). Water content is too low, pressure is not true, moisture is too high, juice oozes out, nutrient loss is large, and silage acidity is increased, palatability is reduced, and moisture content may be adjusted by increasing dry straw or water spray.
Different silage feed silage technologies are different. Wheat silage such as ryegrass is easy to harvest at the heading stage. High moisture content can be properly sun-dried, then cut short to 2-5 centimeters, and the cellar density is generally 600 kilograms per cubic meter. After the compaction, the upper layer covers the plastic film, and then covers more than 5 cm of sand or other heavy objects, the minimum fermentation time is not less than 21 days; corn silage including the cuttings of Emperor bamboo grass is easy to cut short to 2-3 cm, the density is generally 550 Kg/m3, the same sealing conditions as ryegrass, the minimum fermentation time is not less than 30 days.
Silage production procedures: 1, ready. The silo needs no cracks and no seepage; the green feed adjusts the moisture content according to the situation after harvesting; the raw materials must be cut short in order to facilitate practical compaction and maximize the discharge of air, so as to create an anaerobic environment for the fermentation of lactic acid bacteria, and after shortening, Contains soluble sugars that easily flow out, providing nutrients for lactic acid bacteria, promoting lactic acid bacteria fermentation, and easy silage. Crude materials should be cut shorter and finer materials can be slightly longer. 2. Loading and sealing of silage facilities. Silage raw materials will be cellar, layered and practical compaction, loading to half an meter higher than the cellar surface, sealed, it is best to complete the filling within 1 day. 3, after storage management. At any time, check whether the cellar wall of the cavern roof is sealed and exposed on the ground for cracks and collapses. It is necessary to promptly repair and drain the water at the top to prevent air immersion.
