Flammulina velutipes as a kind of edible mushroom and medicinal strain with high economic value, its economic value determines it has a broader market prospect. The main points of industrial production management of Flammulina velutipes are as follows: The production technology of industrialized mushroom (velvet mushroom) production usually takes about 53 days for a cultivation cycle. The key technologies for industrial cultivation of mushroom are summarized as follows: 1. Cultivation materials: Cultivation materials mainly include cottonseed hull, bran, corn cob and rice bran, accounting for about 90% of the total. Corn flour, calcium superphosphate, and calcium carbonate account for 10% of other accessories. Adjust 60%-65%. 2. Bottling, Sterilization and Cooling: Mechanical mixing and bottling are used. The requirements for mixing materials are uniform. Each bottle is loaded with 850 g of raw material. The surface is compacted, a hole is made in the middle of the bottle, and a filter cover is covered to ensure the bacteria. The normal growth of nutrient sources and air. 3. Inoculation: The cultured good strains will be inoculated mechanically and automatically under aseptic conditions. The inoculation volume is 10 g/bottle and the 850 ml bacteria strainer bottle can be connected to 80-90 bottles. 4. Mycelial culture: Inoculated mycorrhizal flasks were cultured in a dark room under certain conditions of temperature, humidity, and culture time. Flammulina is very sensitive to light and must be cultivated in a dark room. 5. Mushrooms: After the mycelium is full, the fungus is operated. That is, remove the cap and use a fungus machine to remove the old bacteria from the bottle. 6. Inhibition: After completion of the prolapse, send to the antibacterial room for inhibition culture, technical parameters: temperature 3 °C -5 °C, relative humidity 80% -85%, time 5-7 days, while appropriate ventilation, every 4 Ventilate for 15 minutes. After 5-7 hours, a clear cap and stipe can be grown. And note that the light can not be strong to improve the quality of the fruit body. 7. Growth: When the bacteria cup grows 1 cm from the bottle mouth, the room temperature is adjusted to 6°C-8°C, and light treatment is performed to improve the quality of the fruit body. When the fruiting body grows 3-4 cm from the bottle mouth, the paper (plastic) tube must be put in a timely manner. 8. Harvest: When the stipe reaches 13-15 cm and the diameter of the cap is about 1 cm, it can be harvested. 2-3 days before harvest, the fan is turned on to allow the water to evaporate, so that the relative humidity of the cultivation room is maintained at 70%-80%, which can improve the product quality and extend the shelf life. 9. Packing and preservation: The mushroom body after harvesting shall be placed separately according to different grade requirements, and the connecting part of the base of the stipe and the culture medium shall be removed. The packaging of different sizes shall be carried out according to the market requirements, and the polyethylene film bag shall be used for pumping. Hermetically sealed, low temperature refrigeration after packaging is completed. Rhodium powder Rh≥99.95% Properties: silver-white metal, extremely hard, wear-resistant, also has considerable ductility Application: It can be used as raw material for electrical instrumentation, chemical industry and manufacture of precision alloys. Rhodium powder is based on the widespread use of ruthenium in the industrial industry. Since rhodium is a rare metal required by the industry, the industry price is slightly higher than that of general non-ferrous metals. Rhodium, one of the rare elements, has various uses. Rhodium can be used to make hydrogenation catalysts, thermocouples, platinum-rhodium alloys, etc. It is also often plated on searchlights and reflectors, and is also used as a polishing agent for gemstones. and electrical contact parts. precious metal XI AN RHINE BIOLOGICAL TECHNOLOGY CO.,LTD , https://www.rhinebioteches.com
