With the continuous improvement of feed silage methods, there are many types of silo.
(1) Silage cellar: It can be built into two kinds of crypts and cement cellars. It is a kind of mantle-like structure. The construction cost of crypts is low. It is more suitable in mountainous areas with less rainwater and good drainage; brick or stone for cement cellar walls. Blocks are built, 20 cm to 30 cm above the ground, and the inner walls are plastered with cement, which is costly. The walls of the cellar should be smooth and straight, and the upper end of the cellar must be wider than the bottom so as to prevent the soil from falling around; the bottom of the cellar must be sloped to eliminate excessive juice in the forage. Put the plastic film in the dug-out cellar so that the stored forages are all wrapped in plastic film.
When making silage in the cellar, care should be taken to prevent the mud from mixing in the forage grass. The mixing of the soil can cause the loss of the forage grass to deteriorate. At the same time, the cellar should not be too large. The number of each pit should not be too much, and multiple excavations can be used. A re-enable one to protect the quality of silage.
(2) Ground silo: It is more suitable in areas with more rainwater and higher groundwater levels. In other areas with conditions, permanent ground pits can also be built. The bottom of the silo is above or slightly below the ground, and the entire cellar wall and pit bottom are made of stones or bricks. The inner wall is cemented to make it straight and smooth. The cellar walls are generally 2.5 to 3 meters high and 10 to 50 meters long. The bottom of the pit is not water seepage. In addition to a certain slope, there should be better drainage around the cellar, in particular to prevent surface water from pouring from the entrance of one end. At the same time, the height of the pit should be suitable, not too high, too high, it will be more difficult to load and step on the real-time, and at the same time it is easy to make the hay that is directly blown into the pit by the lawn mower floating from the top to cause waste.
