There are many silage devices, such as pits, towers, concrete, plastic bags, etc. Now introduce silage silage underground suitable for family feeding. 1. Jianye 1. Location: Silage should be built on a high ground, with a low groundwater level, sheltered from the sun, good drainage, and near the house. 2, digging hoe: 壕 according to the ratio of width, depth 1:1 to dig, according to the size of the amount of silage to choose the appropriate specifications, commonly used 1.5 meters 1.5 meters, 2.0 meters 2.0 meters, 3.0 meters 3.0 meters and other kinds, length It should be decided according to the amount of silage. Generally 1 cubic meter can accommodate about 700 kilograms of silage. The wall should be "flat" and "straight." "Ping" means that there should be no bumps in the wall, and if there are irregularities, the gaps in the feed will sink and the feed will become moldy; "straight" means to go straight up and down, and the wall should not be tilted. Don't go up or down or go up and down. , otherwise it's easy to burn. The side walls can be dug at right angles to the bottom, but it is best to dig into an arc to prevent gaps and moldy feed. One end of the raft was dug into a 30-degree slope to facilitate the use of silage. 3, 壕: Silage 壕 according to different years of use are divided into temporary and permanent 壕 two. Temporary earthworms are mostly earthworms. After the earthworms are dug up, a layer of non-toxic polyethylene plastic film is added on the floor and around them. After 1 year of use, the wall needs to be repaired in the second year to be used. If you use it for a long period of time, it is best to use cement, bricks, stones, etc. to build a permanent file. Although the one-time investment is large, it can reduce the trouble of repairing and digging each year. Second, stocking All non-toxic, non-thorn, no strange taste of grass, leguminous, vegetable crop stems and leaves are the raw material for the production of silage, silage raw material moisture content should be maintained at 65% to 75% (chopped raw materials Clenched hands, fingers leaking water droplets). Corn is widely cultivated in China. Corn stalks with several green leaves are an excellent silage material. The silage of corn stalks is mainly introduced. Silage corn stalks should be harvested immediately after the maturity of the corn kernels. At this time, only a few leaves in the lower part of the corn stalks turn yellow and the water content is about 65%, which is suitable for silage. If the harvest is late, the corn stalk is still green, but the leaves have turned yellow. At this time, the whole plant has a water content of about 50%, and it can still be silage, and it can be sprayed with water when it is silage. It is best to use silage only in the upper half of the stem. When the maize grain is just mature, it is better to harvest corn silage above the cob (sharp silage). After preparing the raw materials, the raw material is cut into 3 cm lengths with a lawn mower or a guillotine blade for preparation. Third, the equipment will be evenly cut short raw materials in the silo, each loaded 15 to 20 cm thick practical 1 times, piled to 20 to 30 cm above the ground will stop stacking. In order to increase the nutritional value of silage and meet the protein requirements of herbivores, urea can be uniformly dispersed in the filling process at a rate of 0.3% (for ruminants such as cattle and sheep). Fourth, after the top storage material is filled and pragmatic, carefully wrap the top with a plastic film, seal it with 30 cm thick soil, and dig a drainage ditch around it. After 7 to 10 days, the sinking rate of silage is larger, and the pressure soil is prone to cracks, and the cracks appear to be sealed at any time. 5. After taking the silage for 30 to 50 days (30 days high and 50 days low) after taking the seal, the silage can be opened from the end with a slope, and the animals will be fed. Note: After the silage is opened, it should be taken every day to avoid silage deterioration and feeding.
