In recent years, in some rice-producing areas, micro-storage rice straw has been used to feed dairy cattle, beef cattle and sheep, and most of them have achieved good economic benefits. However, due to the high content of silicate in rice straw and the low content of carbohydrates, it is necessary to prepare rice straw into edible micro-storage for ruminants. In the production of micro-storage, the following steps should be strictly followed: Tons of rice straw as an example). First, the resurrection of the strain: first add 2 grams of white sugar in 200 ml of water, fully dissolve the white sugar, prepare a 1% sugar solution, and then a small bag of starfish "micro-storage king" straw fermentation bacteria Pour into the prepared sugar solution and let stand for 1-2 hours. This is because the starfish "micro-storage king" is made up of lactic acid bacteria, fiber-decomposing bacteria and propionic acid bacteria. The lactic acid produced by the lactic acid bacteria can be completely absorbed and utilized by the livestock. The fiber-decomposing bacteria can decompose the cellulose and hemicellulose in the rice straw, and the propionic acid bacteria can play a certain role in preventing mildew and antisepsis. Because lactic acid bacteria use sugar as a nutrient for growth and growth, the 1% sugar solution can be used to increase the resurrection rate of the strain during resurrection. But be careful not to add more sugar, the concentration of sugar is too high, but will reduce the resurrection rate of its strain. Second, the preparation of bacterial liquid: First, prepare 1% salt solution, after the salt is fully dissolved, pour the revived strain into the salt solution. The water consumption should be determined according to the water content of the micro-storage rice straw. (The water content of the newly harvested rice straw is higher, the water consumption will be less, and the water consumption will be more after drying or long-term rice straw). The water content of rice straw is about 55-65%. When the water is too much, the storage material is easily rotted and deteriorated. If the water is small, the fermentation will be insufficient. The amount of salt used is calculated based on the amount of water used. One ton of rice straw after drying, use 1200 litres of water for 1-1.2 kg of salt. This part of the salt can be deducted from the livestock diet. Third, the cut of rice straw: to choose fresh, no mold to change rice straw. In order to facilitate compaction during dressing, the rice straw must be cut short. The length of the straw cut can be determined according to the animal to be fed (bovine: 5-8 cm; sheep: 2-3 cm). It is also possible to use a straw smashing machine to smash the rice straw and then decorate it. The purpose of cutting the straw into short or simmering is to facilitate compaction during dressing and to facilitate livestock feeding. But for ruminants, the straw can not be cut too short, otherwise it will cause ruminant indigestion. 4. Construction of micro-storage: The size of micro-storage should be constructed according to the number of livestock kept. The amount of micro-storage straw required for livestock is calculated on a one-year cycle: cows, beef cattle/years 7-8 tons, horses, donkeys, donkeys/years 3-3.5 tons, sheep/year 1 tons. Generally, one cubic meter of micro-storage can store 300-350 kilograms of rice straw (calculated as dry matter). The shape of the micro-storage is preferably constructed in a rectangular, underground or semi-subterranean manner. V. Decoration: firstly put a layer of 20 cm thick rice straw on the bottom of the crucible, and then spray the prepared bacterial liquid evenly on the straw, and the Check the moisture at any time. Check the moisture, you can use the method of hand-screw, grab the straw in the compacted straw, and twist it by hand. If the water is dripping, the water will be added more. If the palm is only wet, the water is added less, only the straw is caught. When the finger is seen, the water does not drip, and the water content of the straw is about 60%. While spraying the bacterial liquid, evenly spread the cornmeal with 1-2% of straw (one ton of rice straw added to 10-20 kg of cornmeal). This is because the content of carbohydrates in rice straw is low. The purpose of adding cornmeal is to provide certain nutrients for the reproduction of lactic acid bacteria in the early stage of straw fermentation, so as to improve the fermentation quality of micro-storage rice straw. When installing the stalks, compact the stalks and lay a layer of solid laminate. Pay special attention to the edges and corners of the sputum. This is because the lactic acid bacteria in the micro-storage fermentation are anaerobic bacteria, and only in the anaerobic environment, the lactic acid bacteria can normally grow and multiply to produce a large amount of lactic acid. Therefore, only the air in the storage material should be discharged as much as possible to ensure the normal reproduction of microorganisms and to produce high-quality micro-storage feed. If it is not fully compacted, there may be mold and deterioration. Sixth, the seal: it can be sealed when it is laminated to 40cm above the mouth. 250 grams of salt per square meter on the surface of the storage material before sealing to prevent mildew on the surface of the storage material. After spraying the salt, cover the plastic film and cover the soil. The reason why it is crushed is because the straw will sink when it is fermented. If it is not crushed, it is possible to pour the air outside the sputum into the sputum. Before the soil is covered, 20 cm thick rice straw is placed on the plastic film, so that the soil will not contaminate the storage material when the soil is opened. Where conditions permit, you can also use sandbags to crush. VII. Reclamation: The micro-storage rice straw is basically the same as the traditional silage when it is opened, and it should be taken vertically from top to bottom. In the winter, if the micro-storage is frozen, the ice must be first opened and then fed to prevent the hail from scratching the livestock. In the summer, in order to prevent secondary fermentation of the micro-storage rice straw, the cornice is covered with a plastic film after each take-up. In the high temperature and high humidity season, it is also possible to spray a high concentration of salt water on the surface of the stock after each take-up to suppress mildew. Exterior Wall Rock Wool Insulation Board Rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material through high temperature melting processing. It was successfully tested in June, 1981. Rock wool board is a new type of thermal insulation, flame-proof and sound-absorbing material.

The artificial inorganic fiber made of rock wool board by high temperature melting process has the characteristics of light weight, small thermal conductivity, heat absorption and incombustibility. The initial development is a common type of application in construction, which is mostly used in industrial buildings. It should meet the requirements of "Application Types and Basic Requirements of Building Thermal Insulation Materials". Rock wool is a kind of external insulation material. When the market share of 90% of the organic thermal insulation materials is stagnant, rock wool, as an inorganic thermal insulation material for exterior wall, has ushered in an unprecedented market opportunity.
