In general, the texture of straw is hard and rough, the chewing of animals is difficult, palatability and nutrition are all very poor, especially the high cellulose content of yellow wheat straw and rice straw after harvesting wheat and rice, and the low protein and soluble sugar content Feeding cattle and sheep with this straw is not only poor in palatability, but also directly affects the increase in production capacity. Micro-storage is the addition of a microbial composite strain called “straw rapid microbiological biological additive†to these crop straws. Through 10-15 days of sealed storage, these crop straws can be turned into a soft texture, moist and swollen, and smelly. Fragrant, cattle, sheep, pigs and other animal feeds. First, straw micro-storage method. 1, cement pool micro-storage method. Similar to the traditional silo, the crop straw was chopped, and the bacteria solution was sprayed in proportion and then loaded into the pool. The layers were compacted and sealed. This method is not easy to enter the pool water, sealing, and durable. 2, crypt storage method. Select a place with high topography, hard soil, sunny drying, easy drainage, low groundwater level, close to storage, convenient access, dig a rectangular cellar (2-3 meters in depth), and Laminate the plastic cloth around, cut the straw and put it into the pit, spray the bacteria liquid layer by layer, compaction, cover the plastic cloth, and then cover the soil. This method has a large amount of storage, a low cost, and a simple method. 3, the plastic bag cell micro-storage method. First, select the site according to the storage method of the cellar, dig a round cellar, put the prepared plastic bag into the cellar, layered and sprayed the bacterium liquid, compact the mouth of the plastic bag after compaction, compact the cover soil, apply to a small amount Micro-storage 100-200 kg. Second, the preparation of straw micro-feeding steps 1, bacteria revival. Straw fermentation live dried bacteria 3 grams per bag, can handle 1000 kg of straw or 2,000 kg of green straw. The bacterial preparation is first poured into 200 ml of water and fully dissolved, and then placed at room temperature for 1-2 hours to rejuvenate the strain (the revived strain must be used the same day, not overnight). Then resuspend the well-being liquid into well-dissolved 0.8%-1.0% saline and mix well. 2, the length of the straw. For storage of straw must be short, the length of 3-5 cm is appropriate. 3, straw into the pit. Put 20-30 cm thick straw on the bottom of the cellar, evenly spray the bacteria liquid water, and then spread 20-30 cm after compaction, and then spray and then compact until 40 cm from the cellar mouth and then seal it. If the day is not finished, you can cover with plastic film to continue the next day. 4, sealed cellar. Layered, compacted, until the cellar 30-40 cm higher, and then fully compacted in the top layer evenly sprinkled with salt powder, and then covered with plastic film after compaction. Amount of salt 250g/m2 was used to ensure that mildew does not occur in the upper part of the microbe. After covering with a film, spread 20-30 cm of rice straw powder, corn flour, wheat straw, and 15-20 cm cover soil to separate from the air. Keep the anaerobic state in the micro-cell. Third, pay attention to matters 1, can be added in the production of 5% barley flour, wheat bran, corn flour, but should be stratified as stratified into the straw, the purpose is to breed nutrients. 2. Grab the straw sample in production and twist it with both hands. If there is water dropping, its moisture content is about 80%; if there is no water drop, loosen the hand moisture is obvious, the water content is 60%; There is about 50% of water (reflection); the hand feels about 40-45% wet, and the humidity is less than 40%. Micro-reservoir requires moisture at 60-70%. 3, the general storage can be fed after 20 days. Take the feed should start from the corner, from top to bottom paragraph by paragraph. 4. Seal the mouth immediately after each take to avoid rainwater immersed in deterioration. 5, micro-storage can be used with other grass, fine material, livestock feeding should have a process of adaptation, step by step, and gradually increase. 6. The appropriate amount of salt is added during the production of micro-feeds. This portion of salt should be deducted from the diet fed to livestock. Special attention should be paid to the top layer of the cellar sprinkled with more salt. After the production, it is necessary to check in time, because of the sinking of the storage, earth should be timely, digging drainage ditch and so on.
