Straw micro-storage is a new technology that uses microbes to treat straw. The straw after micro-storage was better than the untreated straw. Compared with the ammoniated treatment, the crude protein content of the micro straw was lower than that of the ammoniated straw, but the feed intake and daily gain were higher than that of the ammoniated straw, and the cost was also lower than that of the ammoniated straw. Ammonia treatment is low. Micro-storage technology can be used as a new method of processing straw feeds for production. 1. The micro-cell pit is divided into cement pit and crypt. The pit of the cement pool is well-grounded, square, and about 30 centimeters above the ground. The inner and outer walls of the pit need cement plastering, and the inner wall needs light. The crypts are to be selected where the terrain is high, the soil is hard, the drainage is easy, and the groundwater level is low. The shape of the pit is round or square, and the plastic film used in the pit bottom and surrounding areas can be sold on the market. After turning one end of the knot, turn it over so that the knot is in contact with the feed. The cellar depth is 1.5-2 meters. The cellar area is determined according to the number and size of the cattle, 0.5-0.8 square meters per cow, and corn straw as raw material should be larger. Wheat straw and rice straw should be used as raw materials. It is best to build 2-3 cellars at the same time for family cattle and sheep for rotation. Only raising a cow with wheat straw and straw as raw materials should not be used for micro storage. The micro-reservoir has a bulk density of about 150 kg per cubic meter (air-dried material). 2, the raw material of green corn stalks, yellow corn stalks, wheat straw, straw, wild grass, sweet potato pods can be, but the wheat glutinous rice and rice mash can not. Raw materials require no mildew and no pollution. Straw should be short: dry straw should be short, 2-3 cm; green straw is slightly longer, 3-4 cm. 3. Additives According to the test, barley flour and corn flour have better effect than bran, and the amount of addition is different depending on the raw materials. The green corn stalk does not need to be added, the amount of yellow corn stalk is 0.5% of the raw material, straw and wheat straw are 1.5. -2%. 4. The rejuvenation of the bacterium stalks Fermentation of live dried bacteria 3 grams per bag can handle 2000 kilograms of green stalks or 1000 kilograms of dry stalks. Take 200 ml of tap water, add 2 g of white sugar to dissolve (no sugar is also available), then pour 1 bag of bacteria into the solution and leave at room temperature for 1-2 hours. The revived good bacteria must be used up on the same day, otherwise it will lose its effect. 5. If there is a large water container for broth preparation, calculate the amount of water according to the amount of straw and the adding rate at one time, and prepare a 0.8-1.0% salt solution, and then pour the revived good agent into the mixture. If the container is not large enough, a 0.8-1.0% salt solution can be prepared according to the size of the container, and the revived bacteria can be added in proportion. This is repeated several times. 6. Put the cellar on the cement floor or plastic film outside the cellar. Put about 20 centimeters of straw in the cellar each time. Sprinkle the required amount of broth, and sprinkle a certain amount of cornmeal. Stir thoroughly after mixing. Into the cellar, manpower repeatedly presses on the actual, in particular, can be used around the wood sticks (the crypt can not be used wood bar, can only use the foot). This is the case for each floor until it is about 30 cm above the cellar. The top of the pit should be relatively flat with the middle being 5-10 cm higher than the side. 7, moisture inspection and control Micro-storage straw, the ideal moisture content is 60-70%. Add water when there is insufficient water. The inspection method of water content is: take the sample and twist it with both hands. If the water drops down, the water content is more than 80%; if there is water, but not drip, more than 70%; if the water drops and release the hand It is evident that the water content is about 60% or more; if the water in the hand is not very clear and there is light reflection, it is about 50%. The moisture content of the straw should increase from the bottom of the kiln to the top, and the upper part should be 10% higher than the bottom part. In the range of ideal moisture content, dry straw should be added more water. 8. After the cellar is installed, sprinkle 250 grams of salt per square meter on top. Then cover it with two pieces of polyethylene plastic film of 0.5 mm or more, one piece is placed under the size of the pit, and the other piece is larger than the pit (the plastic film must cover the surrounding pit walls). Then a thin layer of straw or straw is sprinkled on top of the plastic film and covered with more than 20 cm of soil. Finally, flatten the surrounding plastic film to prevent the formation of space in the plastic film. Use mud to wipe the four sides and the thickness of the mud is more than 10 cm. A plastic bag in the crypt should be sprinkled with salt and then tied with a string. No need to cover soil above. 9. During management of straw micro-storage, it is necessary to prevent leakage of water into the water. The top of the cellar and its surroundings must be well drained and no water can accumulate. The upper clay cracks caused by sinking in the pit should be filled with fine soil in time. To prevent rat damage, chicken gizzards, if any cracks are repaired with tape. 10. Open cellar opening time depends on the ambient temperature, from May to August 21-30 days, April and September 30-40 days, and other months more than 40 days. 11. Feeding straw micro-feeds must be taken every day, and moldy parts should be removed when feeding. The minimum amount of material to be taken each day differs depending on the composition of the raw materials. Corn stalks are not less than 5 cm, and straw and wheat straw are not less than 10 cm. Otherwise, mildew will occur. After each removal, the micro-materials are covered with small plastic blocks. The cellar door can be covered with plastic film or other things to prevent the rain and other pollution. When microfeeds are used as the main crude feed for cattle and sheep, no additional salt is required for their diets. 12, the quality of identification of high-quality micro-storage of green corn stalks were olive green, rice straw wheat golden yellow, and fruity, weak acidity, get hands feel loose. If the color becomes brown or dark green, the quality is not good; if it is smelly and sticky, it cannot be fed. (Liao Xinmin picks)
