Modulation technology of corn stover silage

1. Silage site and silage container

1. Selection of silage sites. It should be selected in a place with high dryness, easy drainage, low groundwater level and convenient access.

2. Selection of silage containers. There are many types of silage containers, including silage towers, silos (large farms), silos (with long rafts, round rafts), concrete pools (underground and semi-underground), silage bags, and silage bags. It is better for the farmer to use two types of silage containers: a round shackle and a shovel bag.

3. Treatment of silage containers. The round silo is generally 3 meters deep, with an upper diameter of 2 meters and a lower diameter of 1.5 meters. The surface is planed and can be used after two days of exposure, or according to the size of the plastic bag, a circular file slightly smaller than the bag is dug. Light wall surface, ready for use after drying.

Second, the filling of silage

1. Acceptance. The corn stalks that have been harvested after harvesting the seeds are transported to the silage squats in time. The shorter the time of collection and transportation, the better, so as to maintain more nutrients in the raw materials and prevent excessive water loss.

2. Cut and install. The corn stalks of the boudoir are chopped about 2-3 cm long, and a layer of 20 cm thick dried wheat straw is placed on the bottom of the shovel. The chopped corn stalks are placed in the sputum, and cut, side, and solid. In particular, the surrounding area of ​​the cockroach should be more practical, until the height of the sputum is 20~30 cm.

3. Seal. After the enamel is filled, the top is covered with a layer of plastic cloth, and the cover is covered with a soil layer of more than 30 cm thick and sealed. Dig the drainage ditch around the next week.

Third, the maturity of silage

1. Maintenance of silos. With the maturity of the silage and the pressure of the soil layer, the silage in the crucible will slowly sink, and cracks will appear on the soil layer, and dew will appear. In case of rain, the rain will penetrate from the gap and the silage will be destroyed. Sometimes, due to the unsatisfactory trampling in the decoration, the time is a little longer, and the silage will appear below the ground, and the rain will accumulate water. Therefore, it is necessary to observe the silage at any time and find cracks or sinking. It is necessary to cover the soil in time to ensure the success of silage.

2. Mature. The filled silage is fermented under the action of bacteria, and the corn stover silage generally takes 1.5-2 months to mature. Fourth, the opening of silage

1. Unsealing. After the silage is mature, it can be unsealed for feeding. The round enamel should be unsealed from above, taken from the side, with a depth of about 40 cm. After the upper layer is used up, the second layer is taken. The long scorpion should be unsealed from one side. Take one day of material each time. After the material is taken out, the straw curtains and the like are covered and the waste is cleaned.

2. Feeding. The amount of silage to be fed should be reduced from small to large, so that livestock and poultry can gradually adapt. Mildewed feed cannot be fed. The amount of feeding depends on the species, age, weight and physiological condition of the livestock. Pregnant animals should be fed less.

5. Silage quality inspection

Silage quality assessment is often used in the production of intuitive methods, that is, to observe its color, smell its taste and feel its quality.

1. Color. Excellent silage color is green or yellowish green, shiny, close to the original color. Medium quality silage is yellow or dark brown in color. Inferior quality silage is black, brown or dark green.

2. Smell. Excellent silage has an aromatic acidity. Medium quality silage with a light aroma or pungent acid. Inferior silage is musty, pungent odor. 3. Texture and structure. The excellent silage is soft, easy to separate, moist and compact, and the stem and leaf flowers remain intact. Medium-quality silage is soft, with plenty of water, and the stems and leaves are kept intact. Inferior silage is sticky, sludge-like, and has no structure.

Sixth, the key to the success of silage production

1. The raw material must have a certain water content. Generally, the moisture content of raw materials for silage should be kept at 65%~75%, lower or higher than this water content, and it is not easy to silage. If the water is high, it is necessary to increase the water absorption. If the water is low, it is necessary to add water.

2. The raw materials must have a certain sugar content. Generally, the raw material sugar content should not be less than 1% to 1.5%.

3. Silage time should be short. The most effective way to shorten the silage time is to fast, and the general silage process should be completed within 3 days. This requires fast delivery, fast delivery, fast cutting, fast loading, fast stepping, fast sealing.

4. Compaction. The silage must be compacted during installation, and the air in the material should be discharged as much as possible to create an anaerobic environment as much as possible. This is often overlooked in production and special attention should be paid.

5. Sealed. Silage containers should not leak or dew.

Silage can be produced successfully by mastering water, sugar, fast, real and dense.
