Precautions for micro storage of straw, how to micro store corn straw

1. After the straw is loaded, a layer of salt can generally be evenly sprinkled on the top layer according to 250 grams per square meter. It is then covered with a thicker plastic film, which should be slightly larger than the mouth of the cellar, in order to keep the cellar sealed. After the lid is done, the air in the cellar is removed, then sealed tightly, and a layer of hay is added to the plastic sheet to keep it warm.

It is then closed and compacted with soil.

2. After the cellar is sealed, it should be checked in time to prevent stepping on pressure and preventing deep sinking, and if there are cracks or loopholes, it should be blocked in time to prevent water and air leakage. In the process of micro-storage, it is necessary to prevent water leakage, once the water leaks, the straw is easy to rot and deteriorate. The length of fermentation varies depending on the temperature.

Generally, under the temperature of 10-40 days, micro-storage fermentation can be completed after 10-15 days.

3. After the micro-storage and fermentation are completed, it can be opened and used. When opening the cellar, the plastic film should be removed from one end of the cellar, and the vertical application should be taken from top to bottom. After use, seal it with plastic film, and do not uncover all the plastic film, otherwise, there will be a large amount of air entering the cellar, which is easy to cause secondary fermentation and make the straw rot and deteriorate.

Introduction:Straw micro-storage is the fermentation and storage technology of crop straw agricultural, which is a straw treatment method for crop straw to improve its nutritional value.

In recent years, the popularization and application of straw treatment technologies such as straw ammonia, alkalization and silage have made positive contributions to the rational development of feed resources and the full solution of forage and feed problems, and have achieved huge economic and social benefits. However, silage has high requirements for straw and is more seasonal: and the transportation of ammoniated liquid ammonia and ammonia water is very inconvenient and unsafe.

Add starter culture, bagging anaerobic fermentation baling, and use bagging micro-storage hydraulic equipment.

Cut the corn stalk short, the length is 5 cm 8 cm for cattle and 3 cm 5 cm for sheep, and the pig needs to be crushed, so that it is easy to compact and improve the utilization rate of the micro storage cellar and ensure the production quality of the storage material.

The container can be similar to silage or ammoniated cement cellar or soil cellar, the bottom and around the layer of plastic film, small batch production can be used cylinders or plastic bags, vats, etc. The moisture content of the straw is controlled at 60% to 70%, and the active microbial strains are added to the straw to make the corn straw fermented and become a feed that livestock like to eat with acid, aroma and wine flavor.

The method of micro-storage and utilization of microorganisms to degrade and convert cellulose and hemicellulose in corn straw into bacterial protein is also the trend of crude fiber utilization in the future.

Find a straw micro-storage technology teaching CD to study, you can master the corn straw micro-storage technology in detail.

1.There are many ways to process silage technology from corn stover. The preservation method of keeping the corn stalks green or partially green after the autumn harvest Hu annihilation.

The common and ideal storage method is cellar storage, although the one-time investment is larger, but it is durable, long service life, can be made all year round, and the storage capacity is large, and the quality is also used more in rural areas. The preferred site should be located in a place with high terrain, low groundwater level, leeward and sunny, solid soil, close to the farm, and convenient access to silage. The shape of the cellar is generally rectangular, and the size and depth can be selected according to the number of cattle and sheep raised, the length of feeding time and the amount of forage that needs to be stored.

The walls of the cellar should be as smooth as possible, and the edges can be plastered with cement or stacked with adobe; Just pay attention to waterproofing and air leakage.

2.The second is storage, wrapping silage is a method of using mechanical equipment to complete straw or feed silage, and a new type of forage silage technology is researched and developed on the basis of traditional silage. It is to use the crushed silage raw materials with a baler for high-density compaction and baling, and then wrap them with film through the wrapping machine to create an anaerobic fermentation environment, and finally complete the lactic acid fermentation process.

This method is widely used in European agricultural and pastoral countries, and in recent years, some regions in China have begun to try to use it, and gradually become commercialized. Compared with conventional silage preservation, it has a small dry matter loss, a long shelf life, good texture, good palatability, high digestibility, small loss of nutrients, and the production is not limited by time and place, as well as transportation and use are more convenient, which is conducive to commercialization, so it is gradually accepted by everyone, and it is also of great significance for the development of silage processing industrialization.

3.Cattle and sheep feed sheep feed, cattle feed, sheep premix, beef cattle premix, cattle and sheep feed additives are inseparable from the feed raw materials, corn straw as silage feeding cattle and sheep also play a major role, because it has a fragrance, can enhance cattle and sheep appetite, is a necessary raw material for feeding cattle and sheep. Silage corn feed has perfect nutritional value, good palatability, easy digestion, meets the nutritional needs of beef cattle, dairy cows and other livestock in winter and spring, and keeps beef cattle and dairy cows in a high level of nutritional status and production level, which is one of the indispensable basic feeds for beef cattle and dairy cattle industry.

In recent years, the beef cattle industry has developed greatly, providing a large amount of beef to domestic and foreign markets, and many places have become famous cattle counties. The dairy industry is recognized as a grain-saving, economical and efficient industry, and it belongs to the "vegetable basket pants early flush" project. Milk is also the nutrient with the highest feed conversion rate.

Therefore, the development of dairy cattle industry and the promotion of silage corn can drive the sustained and rapid development of China's animal husbandry. Countries with developed animal husbandry in the world attach great importance to the cultivation and production of silage corn. For example, France, Canada, the United Kingdom, the Netherlands, Germany and other countries have cultivated a large number of silage corn varieties.

In many countries in Europe and the United States, silage corn feed has long been the main active energy component in ruminant animal diets and fortified feed for young animal fattening.

You can wrap these things in plastic wrap and put them in a cool place to play a good storage role.

Keep these things in a cool place, not exposed to wind and sun, so that they can be better stored.

It can be stored in a dry, warm place, so that it will solve the problem, be sure to pay attention to the surrounding situation.

1. Fermentation and laughter. First, the corn stover is fermented, and the fermented corn stover is more convenient to store and can also be stored for a longer time.

2. Cellar storage. Cellaring is a very common storage method, and it is able to store corn stover with a large reputation of sail content, so if you want to store large quantities of corn stover for a long time, you can use this method.

3. Storage. Packing storage is a kind of straw storage method completed by machines, which can crush the straw, then ferment, and then store.

1. After the straw is chopped, collected or manually harvested at one time through the silage harvesting machinery, the green corn straw is crushed to 1 cm 2 cm long to make its water content 67% 75%, and it is packed and stored in cellars, cylinders, towers, pools and plastic bags for compacting and sealing storage;

2. Artificially create an anaerobic environment, naturally use lactic acid bacteria anaerobic fermentation to produce lactic acid, so that most microorganisms stop reproduction, and lactic acid rolling bacteria due to the continuous accumulation of lactic acid, and finally stop digging and slowing down due to the continuous accumulation of lactic acid, and finally stop digging and slowing down, so as to maintain the nutrition of green straw, and make silage with a slight fruity flavor, livestock prefer to eat.

3. Factories using straw as raw materials: power plants and ethanol plants, straw is converted into electricity and fuel ethanol, which can alleviate the situation of energy and food shortage, which can be called killing two birds with one stone.

During the harvest season, straw burning is serious, which will increase environmental pollution and is also one of the causes of haze. In some places, straw burning is prohibited, and violators are punished. An effective way to do this is to use a bale net, where the straw is packed into bales, which can usually be stored outdoors for a year, and the straw can be used comprehensively.

It should be straw micro-storage technology! Whether it is fresh straw or dried straw can be micro-stored, the difference between fresh straw and dried straw is the difference in regulating the moisture after fermentation. Generally, straw starter culture is used for micro-storage to shorten the fermentation time and improve the nutritional value of straw.

First of all, prepare a pack of corn straw starter culture, 1 kg of brown sugar, 10 kg of sterile water (well water is the best), and a clean plastic bucket.

1: Boil 1 kg of water first, then add 1 kg of brown sugar to dissolve the brown sugar, mainly to eliminate the harmful bacteria in the brown sugar.

2: Then add a packet of straw starter when the brown sugar water has just been melted to 30-40 degrees, stir it, and pour it into the prepared clean plastic bucket.

3: Then pour the remaining 9 kg of water into a clean plastic bucket, stir it, seal the fermentation, and do not leak air. Don't overfill it, it will produce gas during the fermentation process, and it will easily break through the plastic barrel when filled.

5: After fermentation, it is the bacterial liquid, a package of straw starter can ferment 10 kg of bacterial liquid, and 1 kilogram of bacterial liquid can ferment about 200 kg - 300 kg of straw feed.

6: Take out 1 kg of freshly fermented bacterial solution and dilute it with water 1:100.

Then add 200 kg of straw flour, stir evenly, in the stirring process, you can add 10%-15% corn flour or wheat bran and other nutrients to achieve nutritional balance. Then stir evenly again, pay attention to be sure to stir evenly, when you stir well, you try it with your hand, if it feels wet, but there is no water dripping down, then you can seal the fermentation, if there is water dripping down, you can add some corn flour into it. Finally, after it is done, it is OK to seal the fermentation, the fermentation time is 3-5 days in summer, and 5-7 days in winter.

After fermentation, there is a smell of wine.
