Crop straw, such as wheat straw and corn stalk, is an important source of livestock feed. Many farmers are accustomed to shredding and feeding livestock. This practice is unscientific. Because of the large amount of lignin, cellulose and hemicellulose contained in the crop's straw, it is difficult to be digested and absorbed. If the straw is treated before use, the cellulose will be hydrolyzed and swelled, and the absorption and utilization will be greatly improved. Now we will introduce several commonly used alkaline treatment methods as follows: A fire alkali solution method Caustic soda is also called caustic soda. Each 100 kg of straw uses 45 kg of fire alkali, dissolved in 80 to 100 kg of water, placed at room temperature, and can be used for 8 to 10 hours. You can also use fire alkali solution to spray the crushed straw, wet, mix well, stack and compress into block feed for long-term use. Second, the lime solution treatment For every 100 kg of chopped straw, use 12 kg of quicklime, add 200-300 kg of water, add 0.51 kg of salt, mix and store on the concrete floor for 24-36 hours. Third, the mixed solution method The complete straw is laid into a 15-20 cm thick layer and sprayed with 1.5% firebase and the same concentration of quicklime mixture so that the moisture content of the straw reaches about 70%. After compaction, the layers are laid one by one. Spraying, spraying 80 kg of mixed liquid per 100 kg of straw, can be used after being stacked for 7 to 10 days. Fourth, ammonia treatment The stalks were crushed first and packed in the pits for compaction. Then, according to every 100 kg of straw, 12 kg of 25% ammonia solution or 19 kg of 15% ammonia solution should be poured. The temperature in the pit should not be lower than 20°C. After 5 days of sealed storage, it should be taken out for drying. After the smell of ammonia disappears, it can be used.
The M-bus Heat Meters(m-bus heat counter) are the higher
technology development of the heat meters(heat counters). With the M-BUS function, the M-BUS
heat meters can control and read the data from the very far distance and make
the labor free. With the M-BUS heat meters appearance, the whole working
efficiency is improving rapidly.
The
M-BUS heat meters have the working principle like the following: from the
inquiry from the computer, the data will be exchanged from the PC center and
counter. With this function, the M-BUS heat meters not only have all the
functions of the heat meters and but also the function of long distanced data
exchange. SO,this is also called wireless heat meter.
