What is the best place to use for green storage corn stalks, and how big is the place for green stor

Silage does not need to be added in particular, and the key to the success or failure of its technology lies in whether it provides the necessary conditions for the reproduction of lactic acid bacteria. That is, a state of hypoxia, the necessary water and a certain amount of sugar. The sugar content of fresh corn stems and leaves is sufficient for fermentation, which creates good prerequisites for silage.

So, just grasp the two key links.

Guaranteed anaerobic environment. The air in the cellar is eliminated as much as possible, mainly relying on the strict compression of the loading process, reducing the gap between the materials, and the strict sealing of the cellar pool and the cellar mouth to prevent air from entering.

Ensure a certain water content. The suitable water content is about 70%, and the shriveled stems and leaves with insufficient water are not easy to compress, and there is no juice filling in the voids.

As much as the air is exhausted, it is easy to form aerobic respiration, which makes the silage corn smelly; On the contrary, too much water will cause the juice to be squeezed out, nutrients to be lost, and it is easy to make the feed too acidic, so the over-dry material should be sprinkled with water, and the over-wet material should be dried to regulate the moisture.

The production steps of cellar silage are: mowing, crushing, charging and sealing.

Mowing, crushing. In the suitable harvest period of silage corn, choose no rainy weather, mow the whole corn plant, chop it with a chopper or manual chopping, for fresh glutinous corn or bamboo shoot corn after its green ears or corn shoots are harvested, mow and chop as soon as possible, the water content should be 65 75%, if the moisture is too high, it should be cut and dried for half a day before it is broken. Chopping is generally to cut the corn stems and leaves into 3 5 cm long pieces, so that the juice seeps out and maintains a moist environment to facilitate the reproduction and fermentation of lactic acid bacteria.

Over-dried corn stalks can be sprinkled with a small amount of water, so that the water droplets can be squeezed out by hand, and should not be overheated. Silage corn should be loaded with cutting, and the chopping site should be kept clean and refreshing to prevent sundries, especially iron nails, glass and other sharp tools from mixing into silage, so as not to hurt livestock during feeding.

Charge. First of all, the cellar is cleaned, the cellar should be laid at the bottom and the four walls of the non-toxic plastic film, the film should be wide enough to stretch out the cellar to cover the mouth of the cellar, when loading while stepping on the press, layer by layer compaction, the small cellar can be stepped on, the large cellar can be pressed with a tractor or a cow.

Cellar sealing. In order to silage corn has a conducive environment for anaerobic respiration, in addition to compacting, should also do a good job of sealing, in order to isolate the outside air and water into the cellar, silage corn is loaded to about 33 66 cm above the cellar mouth, covered with a layer of non-toxic plastic film, and covered with soil sealing, the soil should also be solid, the soil thickness is 33 66 cm, the top of the cellar is made into a ridge shape, and the cellar mouth is opened all around.

Water ditch, pay attention to the soil surface of the top of the cellar batch leveling, so that about a week after the cellar is sealed, the silage corn sinks, it is easy to observe the cracking of the cover soil, add mud repair in time, and check at any time until it is stable and does not sink.

After the straw is crushed, it is placed in the trench to compact and exhaust, and then sealed to be the green storage straw. It's simple. Just be careful not to leak air or water.

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.

The silage facility must be sealed and covered immediately after being filled and compacted, and the best material for sealing and covering is a large piece of plastic sheeting, which is tightly sealed with 2-3 layers;

Isolate the air from contact with raw materials to keep the facility in a state of hypoxia, and finally cover 20-30 cm of wet soil, the soil should be free of impurities, can not damage the plastic film during operation, destroy the sealing.

When covering the soil, it must be covered from one end to the other, and the air left under the plastic sheet can be driven to the side by the gravity of the soil, until all the air is exhausted, so as to achieve a better sealing effect, and the soil at the top of the trench must be cleared out of the high edge of the trench and it is best to be in the shape of a circular slope to avoid rainwater seeping into the trench.

The feed bag is a fermentation vessel, and it is recommended to use Nongshengle straw starter green storage corn stalks. The principle of fermentation is: the dry straw that is not easy to ferment is added to the fermentation broth of Nongshengle feed, which can decompose the cellulose, hemicellulose and soluble sugars in the material in the anaerobic environment, and convert it into lactic acid, acetic acid, propionic acid and other organic acids through a series of biochemical reactions, so that the pH value can be reduced to, and the reproduction of harmful bacteria such as butyric acid bacteria and spoilage bacteria can be inhibited, so as to achieve the purpose of long-term preservation of the nutritional value of straw.

Due to the addition of microorganisms to the straw, the softness and swelling of the straw are increased, which is convenient for livestock feeding and rumen animals for the digestion of crude fiber. After the use of straw microsilage, the feed intake and digestibility of ruminant livestock increased, and the amount of volatile fatty acids in the rumen increased, so that the protein synthesis of rumen microbial bacteria increased, and the daily weight gain and milk yield of ruminant livestock were effectively increased.

Method of straw fermentation:

1. First of all, the straw that needs to be fermented should be chopped, and the specific length is determined according to the animal's digestive ability and the softness and hardness of the straw. 3-5 cm for sheep and 5-8 cm for cattle (thicker hard straw is relatively shorter).

2. Take out the required fermentation broth according to the ratio of straw powder: fermentation broth = 1:300-400, and dilute the fermentation broth about 50 times.

3. Spray the diluted fermentation broth evenly on the straw powder and stir well.

4. Adjust the humidity to 50%, and grasp the appearance of water seeping out but not dripping with your hands. If the humidity is too high, add some wheat bran to neutralize the humidity, and if the humidity is too low, add some water to adjust.

5. Cover the adjusted straw powder with plastic film (or ferment it with a fermentation tank, tank, barrel, bag), seal it and ferment for 7-10 days, and the fermentation will be successful when it smells sour.

For more detailed technology, you can consult the manufacturer of Nongshengle for full technical support.

Additional: 1. 5-10% wheat bran can be added to the straw powder, which can improve the fermentation rate and the nutrient content in the feed.

2. Users of large-scale fermentation can first measure how much water needs to be added to ferment 100 kg of material to make the humidity reach 50%, and then prepare and ferment broth and water according to this ratio, spray it on the straw powder in batches and times.

3. If the amount of fermentation is relatively large and there is no mixer for stirring, you can also spread a layer of straw powder and spray a layer of fermentation broth. First of all, lay 20-30 cm thick straw at the bottom of the cellar (green fodder can be spread 50 cm), and then evenly spray the straw fermentation broth (green fodder due to the small amount of straw fermentation liquor prepared, it is advisable to use a sprayer, dry straw can be used with a watering can, after compaction, then lay 20-30 cm of straw, then spray the fermentation broth, compact, until it is 40 cm higher than the cellar mouth, and then seal). The purpose of layered compaction is to remove the air from the straw and in the voids.

Creates anaerobic conditions for the fermentation of fermentation bacteria. If the cellar is not full on the same day, you can cover it with plastic film, and open the plastic film when the cellar is loaded the next day and continue to work.

Summary. You can store it in a place of 150 cubic meters. Making silage, is a good way to solve the livestock feed **, the key is the same plant straw, made into silage, will become livestock, very fond of eating, and easy to fat feed, silage storage has two ways, one way is sealed in the cellar, and the other way is to use silage bags to store in the warehouse.

On the ground. 100 tons of green rock storage hand early inspection corn stalks need to dig 200 cubic meters of pits. Silage corn stalks is a good way to solve the livestock feed, silage corn stalks is the corn stalks that have just been harvested with green, crushed and processed and sealed and compacted in the fermentation pond, after a period of natural fermentation, it becomes a nutritious protein feed that livestock loves to eat.

The amount of compacted silage is about 500 700 kilograms per cubic metre, which is about 1 tonne of green fibre silage required in about cubic metres of storage space. If you are making silage for the first time, it is advisable to budget for 2 cubic metres per tonne of space to avoid under-preparation.

Do not dig pits in the ground.

You can store it in a place of 150 cubic meters. The key is that the same plant straw, after making silage, it will become livestock, very wild ants love to eat, and easy to fatten feed, silage storage has two ways to bury, one is to seal in the cellar, and the other way is to use silage bags to store in the warehouse.
