How to ferment sawdust to make nutritious soil
1, stock preparation. 2 m3 of sawdust, 1 bag of microbial fermentation agent, 2 kg of urea (or 50-100 kg of poultry excrement), and 5 kg of rice bran.
2, moisture. The water content of the sawdust must be determined before the amount of water can be determined. The water content of the sawdust to be fermented is adjusted to 60-65% (usually by hand, the fingers cannot fall off the water as a rough standard), and the water content is too high. Or too low are not conducive to fermentation. Then, 2 kilograms of urea were mixed with the appropriate amount of water to make a urea water reserve.
3, the material. Because it is too inconvenient to spread the material evenly, one bag of jinbao biofermenting agent should be evenly mixed in about 5 kilograms of rice bran, so that the mixture of the fermented microbial agent and rice bran can be increased to 6 kg. It is easy to spread it evenly into the pile of sawdust to be fermented.
4, spread the material. The above-prepared fermented microbial inoculant and rice bran mixture are evenly mixed in the sawdust, then, the prepared urea water is sprinkled on the sawdust after being planted, and the sawdust is piled into a pile, and the rear lid is piled up. Upper breathable cover can be.
5. Turn over. After the sawdust is piled up for 7-10 days, the fermentation temperature reaches about 60°C. It can be turned once at a high temperature of about 60°C for 24-36 hours, and then waits until the temperature reaches 60°C. The second time it turns, the second time After turning, naturally leave it for 5-7 days. The fermentation temperature is stable below 40°C to complete the fermentation. Fermentation can be completed 25-30 days under normal conditions (post cooked can be extended to 30-45 days).
An automated analyser is a medical laboratory instrument designed to measure different chemicals and other characteristics in a number of biological samples quickly, with minimal human assistance. These measured properties of blood and other fluids may be useful in the diagnosis of disease.
Photometry is the most common method for testing the amount of a specific analyte in a sample. In this technique, the sample undergoes a reaction to produce a color, and then a photometer measures the absorbance of the sample to indirectly measure the concentration of analyte present in the sample. The use of an Ion Selective Electrode (ISE) is another common analytical method that specifically measures the ions present in the sample.[1]
Many methods of introducing samples into the analyser have been invented. This can involve placing test tubes of sample into racks, which can be moved along a track, or inserting tubes into circular carousels that rotate to make the sample available. Some analysers require samples to be transferred to sample cups. However, the effort to protect the health and safety of laboratory staff has prompted many manufacturers to develop analysers that feature closed tube sampling, preventing workers from direct exposure to samples.[2][3] Samples can be processed singly, in batches, or continuously.
The automation of laboratory testing does not remove the need for human expertise (results must still be evaluated by medical technologists and other qualified clinical laboratory professionals), but it does ease concerns about error reduction, staffing concerns, and safety.
