High-quality silage production technology points

Silage can retain the original nutrients of green and green feed to a large extent, and can effectively kill harmful parasites and microorganisms during anaerobic fermentation of lactic acid bacteria. It is a good quality for herbivores such as cattle and sheep in winter and spring. Forage source. At the same time, because of its simple and easy to learn production process, it is very popular among farmers. However, in order to produce high quality silage, you need to be proficient in some scientific production techniques.

Early maintenance of silage facilities and processing equipment

Before pressing silage, carefully check the sealing condition of silage facilities such as silage and silage plastic bags. If there is damage, repair it in time to avoid silage failure due to air leakage after storage. At the same time, it is necessary to carefully check and debug the safe operation of silage material processing equipment such as mowers, and timely fill the transmission parts with lubricating oil, sanding or replacing the blades of the mower, and tightening the loose screws to avoid processing equipment. Occurrence of accidental safety accidents or affecting the silage process.

Use high quality silage materials

High quality silage materials are the basis for high quality silage. Therefore, when selecting crop by-products such as corn stover and sweet potato vine, while ensuring grain yield, we should try to harvest at the good harvesting period to reduce the loss of various nutrients in silage raw materials. If there are conditions, it is good to plant high-quality grasses such as high-density grass and silage corn to produce high-quality silage raw materials.

Choose to go in sunny weather

When suppressing silage, it should try to avoid the rainy weather, so as to facilitate the orderly development of the harvesting, processing and pressing of silage raw materials.

Keep the environment and raw materials clean and hygienic

Transportation tools, processing sites and silage facilities should be cleaned, and silage materials should be removed from dirt and gravel.

Keep the proper moisture of the silage material

In order to ensure the success of silage, the water content of silage raw materials should be controlled at 65%-70%. If the moisture is too low, the silage material is not easy to be stepped on and the dry mold is caused; if the water is too high, the loss of sugar in the raw material will be aggravated, and the reproduction of the lactic acid bacteria is unfavorable, and the silage is difficult to succeed. Simple method for determining the moisture content of silage raw materials: take a silage in the hand and firmly grip it. If the finger has small water droplets, the water content is greater than 75%; if it is slightly moist, the water content is between 65% and 75%; if not Signs of moisture indicate that the water content is below 65%. Therefore, when the water content is too small, an appropriate amount of water can be added to the chopped silage material; and when the water content is high, the air drying can be appropriately performed.

Chopped length should be suitable

The chopped length of silage is preferably 1.5 cm - 2.5 cm. Too long is not conducive to the compaction of silage, too short to affect the rumen digestion of cattle and sheep.

Maintain proper sugar content in silage materials

The storage quality of silage is related to the fermentation of lactic acid bacteria. The growth of lactic acid bacteria requires a certain amount of sugar to be divided into nutrients. Therefore, the silage must contain a certain amount of sugar, which is generally not less than 1%-1.5% of the weight of fresh raw materials. Corn stems, ears, and potato vines contain enough sugars to easily store silage. However, such as alfalfa, such as legume grass, potato seedlings and peanut vines, etc., which are less sugary, should not be silaged separately, and should be mixed with other silage with high sugar content, or add 5%-l0% rice bran or wheat bran. To increase the content of sugar.

Silage raw materials should be installed quickly

First, you have to carry it with you, follow it, install it, and try to fill it on the same day. The second is to layer-by-layer and step-by-step compaction. The smashed silage should be packed in a 20-cm or so manner before being compacted by humans, etc., and special attention should be paid to compacting the wall and At the four corners, the air in the silage is removed as much as possible to form a large anaerobic state, which is beneficial to the proliferation of lactic acid bacteria.

Strict seal

When the silage is pressed into the silo, the silage is filled 10 cm to 20 cm higher than the cornice, so that it has a middle height and a low peripheral shape. Then, according to the size of the cornice, cover it with a plastic film, and then press a layer of fine sand 40 cm thick. Pay attention to compacting the plastic film around the corners and corners to ensure the silage is well sealed. status.

Strengthen post-storage management

After the filling and sealing of silage is completed, it is necessary to strengthen management to prevent damage to livestock, poultry or worms, and to repair it when it is damaged, leaked or sealed, to prevent silage from secondary fermentation and spoilage. .
