Storage of corn stalks, how to silage corn stalks

Micro-storage technology of green corn straw: if the water content of green corn straw reaches more than 60%, there is no need to add additional water, every 2 tons of silage only need to add 10 kg of cornmeal after a package of good Wang agricultural green feed starter is cultivated, and then sprinkled into a ton of material, and another 10 kg of loose salt is added to the material. It can be strictly compacted and tightly sealed, and anaerobic fermentation is carried out for several days (3 10 days, depending on the temperature).

After the silage of green corn stover, the nutritional value and digestion and absorption rate of corn stover can be significantly improved, and it can be stored until the winter when there is a shortage of feed for livestock, and can also be used to feed pigs.

Precautions: green corn straw microbial silage, grasp the water content of raw materials is the key to the success or failure of fermentation, raw material moisture content to 60 70% as good, generally just cut down green corn straw, water content is higher, to cool 25 hours later, and then used for fermentation treatment, green corn straw silage, generally in order to preserve the nutrients in the green corn straw intact, left to the purpose of feeding livestock in winter, while the nutritional value of silage has also improved.

Reference feeding method for feeding pigs with straw after Haowang agricultural green feed starter treatment: You can refer to the data in the previous fermentation bran feeding method and formula table. In fact, bran is a material that is more difficult to digest and absorb than straw feed, so relatively speaking, fermented straw feed has a better effect than fermented bran feed.

In addition, the easiest way is to directly replace the fermented straw with about 30% of the full price feed, pigs, chickens, ducks and geese, practice has proved that there is basically no difference in the growth rate of the comparison group with all the full price feed, and the coat color is better than the full price feed group, and there is less disease (the fermented straw is wet material, and the weight should be multiplied by 2 in the preparation, that is, if the total amount is 100 kg, if the proportion of the replacement full price feed is 30%, the actual weight is 60 kg of fermented straw).

Micro-storage technology of green corn stalks: if the water content of green corn stalks reaches more than 60%, there is no need to add additional water, every 2 tons of silage as long as a package of good Wang agricultural green feed starter agent, after cultivation plus 10 kg of cornmeal mixing, sprinkled into two tons of material, add another 10 kg of bulk salt, 1% calcium dihydrogen phosphate or superphosphate, strictly compacted, and strictly sealed, anaerobic fermentation, fermentation for several days (3 10 days, depending on the temperature).

After the silage of green corn stover, the nutritional value and digestion and absorption rate of corn stover can be significantly improved, and it can be stored until the winter when there is a shortage of feed for livestock, and can also be used to feed pigs.

Corn straw green storage method:

Green storage originates from the green storage of corn stalks, tender corn planting base, a large number of tender corn broken off wholesale, tender corn stalks have become natural forage for cattle and sheep. Suffering from the fact that there is no grass to eat, but there is no grass to eat in winter, the green storage package came into being. The green storage round bag can be stored for two years, and the grass can not deteriorate at all.

1. Build a cellar: choose a place with high and dry terrain and good drainage to build a cellar.

2. Chopping: The moisture content of straw is required to be about 70%. The growth degree of straw is not more than 2cm, which is convenient for compaction and livestock feeding.

3. Cellaring: First pad 10cm thick hay at the bottom of the cellar to absorb the excess water in the silage straw. Then fill layer by layer, each 15 20cm thick to be compacted, layer by layer until 60cm higher than the cellar mouth print.

Then spread it flat and cover it with plastic film, and seal it tightly on all sides. Spread 1 layer of long straw or wheat straw on the plastic film, and then seal the soil with a thickness of 30 50cm, and after 30 50 days, it can be opened and used. The silage straw is yellow-green, sour and fragrant, soft and loose, does not stick to the hands, does not heat, and has a cool feeling.

4. Feeding method: it is necessary to open the seal section by section and layer by layer, take as much as you want, and reseal the plastic cloth after taking. Beef cattle are fed 10 to 20kg per day.

When making green storage, it must be paved with plastic film at the bottom and around it. Prevent the ingress of air.

How to remove corn stalks and what to put in? This should be a result that it must be placed in a dry environment, and this should not be placed too much, otherwise, this will have a great impact on its growth.

1. Select. When silage, first choose the silage raw material. When selecting silage raw materials, straw with a certain sugar content should be selected, generally not less than 2%, and straw with a sugar content of more than 6% can be made into high-quality silage.

The moisture content of the straw should also be moderate, controlled at 55% and 60%, so as to ensure the normal activity of lactic acid bacteria.

2. Chop. The straw is chopped and the corn straw is cut to 2 3 cm (fed to cattle) or kneaded into silk (fed to sheep). The purpose of cutting short is that it can be filled tightly, easy to use, and easy for livestock to eat.

In addition, after the straw is cut or crushed, it is easy to make the plant cells exudate sap and moisten the feed surface, which is conducive to the growth and reproduction of lactic acid bacteria. The chopped straw is put into the cellar (pool), compacted and sealed and stored.

3. Before loading, cover the bottom wall of the cellar (pool) with a large piece of plastic sheeting, and load the crushed corn straw into the cellar (pool) layer by layer, and use people to step on each 20 30cm thick when the raw materials are compacted, such as stone ramming, crawler tractor pressing, etc., pay special attention to compacting the cellar (pool) wall around to avoid air (oxygen) entering and can not achieve the purpose of anaerobic fermentation.

4. Before sealing the silage cellar (pool), the corn straw should be completely covered with plastic shed film. Press a layer of 300 cm thick wet soil from top to bottom. The bag storage method should tie the bag mouth as tightly as possible without damaging the plastic bag, so that the bag is closed, and press the mouth with a heavy object.

1) Short: According to the difference of raw materials, it should be shorter at 2 10 cm.

2) Filling: The filling speed should be fast, before loading, the bottom of the cellar should be paved with appropriate thickness of broken grass, and the same is true after filling.

3) Compaction: Compaction is an important part of ensuring the quality of silage.

4) Burial: After the cellar is compacted, cover the broken grass with plastic sheeting, and then tamp it with soil.

Corn stalk green storage is not only to ensure the quality, but also to ensure that the nutrients are not lost, there is no more effective way for the time being, if you want to improve efficiency, you can use mechanized operation to save labor time!

Generally, when the corn straw contains 65%-70% of the moisture, you can crush the green storage, dig the green storage pond and fence it with a plastic shed, and then spread the beaten corn straw in the pond layer by layer, and the crushed corn straw is the best.

At 1-2cm, layer by layer with car compaction, do not have air in it, and finally when sealing the pool, it must be surrounded by a plastic shed, and there can be no place for air intake, and the surrounding area is compacted with soil. You can use it after 1 month, start with one side when you use it, and seal it immediately after taking it out. It seems that Shandong Fukang Cattle and Sheep Farm arranges technician guidance for free, and you can consult it.

1) Harvest in time after the corn seed is mature, and after the corn cob is harvested, the corn straw will be harvested within 15 days; 2) Collect fresh grasses and forage grasses, which are ready to use and do not dry; 3) Divide the dry corn stalks into 2-4cm long filamentous short joints; The stems of fresh grasses are cut into 1-3cm short joints by a haymaker; 4) Mix the dry corn straw and fresh forage grass according to the mass ratio of 1:1-2, seal and compact the mixed materials, and stack the packages in the forage shed or flat cement ground in the open air to prevent mice and birds from biting the packaging, and the ground can not be waterlogged in the open air; The bales of forage are anaerobic fermented under the action of microorganisms to achieve the purpose of long-term preservation and storage; Or mix the dry corn straw and fresh grass in the silage pond or silage cellar according to the mass ratio of 1:1-2, and compact, and finally make the compacted material 50-70cm higher than the edge of the silage cellar, spread a layer of dry straw on the top, and then cap with plastic film, so that the capped material does not leak, and after all the compaction, cover the soil with a thickness of 40-60cm; 5) Packaged storage and cellar storage are taken after 45-60 days of sealed anaerobic fermentation.

1. Cellar storage. Cellaring is one of the most common and ideal forms of silage. Although the one-time investment is larger, the cellar is durable, has a long service life, can be made all year round, has a large storage capacity, and the feed quality of the silage is ***.

2. Storage. Wrapping silage is a method of using mechanical equipment to complete straw or feed silage, which is a new type of forage silage technology researched and developed on the basis of traditional silage. The crushed silage raw material is compacted and baled with a baler at high density, and then wrapped in stretch film by the wrapping machine, thus creating an anaerobic fermentation environment and finally completing the malolactic fermentation process.

3. Stacking. Plane stacking silage is suitable for farmers with a small breeding scale, such as raising 3-5 cows or raising 20-50 cows, which can be used in this way, and the characteristics of plane stacking silage are shorter in use, low cost, and less one-time labor input. When making, it is necessary to pay attention to the moisture content of silage raw materials (generally required to be about 65%), compact, and sealed.

These processes have a direct impact on the quality of the silage.

Summary. Dear, I'm glad to answer for you: Can corn stalks be stored semi-dry A:

Corn stover is semi-dry and cannot be stored, and straw is a general term for the stem, leaf (ear) part of mature crops. Usually refers to the residue of wheat, rice, maize, potatoes, rape, cotton, sugarcane and other crops (usually coarse grains) after harvesting the seeds. More than half of the products of crop photosynthesis exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc., and is a renewable biological resource with multiple uses, and straw is also a kind of roughage.

It is characterized by a high crude fiber content (30%-40%) and contains lignin, etc. Although lignin cellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock.

How to store it.

It can be stored by micro-storage processing technology, that is, biological treatment methods. Small batches can be made by packaging plastic bags, and microbial active strains are added to the bags to make the corn stalks fermented into sour, fragrant, and wine-flavored feed. It can be stored by micro-storage processing technology, that is, biological treatment methods.

Silage refers to the method of preserving green and juicy green fodder (fresh corn stalks, pastures, etc.) under anaerobic conditions (through microbial fermentation).

Lactic acid bacteria can only multiply in large numbers under anaerobic conditions, and it is necessary to create an oxygen-deficient environment when making silage. The specific method is to cut the silage raw material short, compact it when it is loaded into the cellar, and seal the kiln roof tightly after it is full.

In the silage process, anaerobic conditions are gradually formed, and there is always residual air in the cellar after sealing, and aerobic microorganisms use this residual air to move and multiply.

When silage is made from fresh ingredients, the plant cells also need air while they are still breathing.

When all this residual air is consumed, the real anaerobic conditions can be created for lactic acid bacteria, so it is best to use fresh raw materials to form an anaerobic environment as soon as possible when making silage.
