Crop straw micro-storage technology Straw micro-storage feed is to add microbial high-efficiency active bacteria-stalk fermentation live-drying bacteria into crop straws, and store them in sealed containers (such as cement silage, soil), after a certain fermentation process. To make crop straws into feeds that have a sour taste and are suitable for herbivorous livestock. It has the characteristics of low cost, high benefit, good palatability, wide source of straw, non-toxic and harmless.
First, the construction of micro-small: Generally choose the place where the terrain is high, the drainage is easy, the soil is hard, and it is close to the animal house. The family raises cattle and sheep, and generally digs 2 meters deep, 1.2 meters wide and 3.5-4 meters long. Spread a layer of plastic film on the bottom and around the crucible. It is best to build two 窖 at the same time for alternate use.
Second, the selection and resurrection of the strain: the strain can be selected by the Xinjiang Academy of Agricultural Sciences Haixing Biotechnology Center (Zip: 830000) to develop a live dry bacteria agent - micro-storage king, 3 grams per bag, can handle 1 ton of straw or green 2 tons of straw. Before treating the straw, first pour the microbial agent into 200 ml of water to dissolve it (conditionally, add 1-2 g of white sugar), and then leave it at room temperature for 1-2 hours to revitalize the strain. Resurrection of good fungi must be used up the same day, not overnight.
3. Water content of the storage material: Pour the revitalized microbial agent into a fully dissolved 0.8%-1% salt solution and mix well. The water content of the storage material should be between 60% and 70%.
4. Straw processing and stalking: The stalks are cut into 3-8 cm (for cattle raising) or 2-3 cm of straw, and the prepared bacterial liquid is evenly sprayed on the straw according to a certain ratio. After compaction, place 20-30 cm thick straw, and then spray the bacteria to the hydraulic pressure until it is 30-40 cm higher than the cornice and then seal. The purpose of the partial lamination is to discharge the air in the straw and the void. If the inside of the crucible is not full, it can be covered with a plastic film and continue to be loaded the next day. When the micro-storage is installed, a total of 5% of barley flour or corn flour and bran may be appropriately added to ensure a certain nutrient for the breeding of the strain at the initial stage of fermentation, and the quality of the micro-storage is improved. When adding wheat flour or corn flour and bran, lay a layer of straw and sprinkle a layer of powder.
V. Moisture control and soil mites: The water content of micro-storage feeds is one of the important conditions for determining the quality of micro-storage feeds. Therefore, the water content of the straw should be checked at any time during spraying and compaction. Pay special attention to whether the moisture between the layers is connected, and the dry layer should not appear. The micro-storage water content is preferably between 60% and 70%. When the straw is laminated higher than the mouth 30-40 cm, it is fully compacted. Spread the salt powder evenly on the top layer, and then compact the plastic film. The amount of salt is 250 grams per square meter. After covering with plastic film, sprinkle 20-30 cm thick rice and wheat straw on top, cover the soil 15-20 cm, seal, do not use mud.
After the micro-storage is fermented for about 30 days, it can be taken out for feeding. When feeding livestock to stocks, they can be paired with other forages or concentrates. The micro-storage should be increased by a small amount to allow the livestock to have a palatable process. When taking the storage material, how much should be used, and then use the plastic film to seal the mouth in time.
