I. Lei Lei 1. Mushrooms: After spraying and sedimenting the workplace with silly silico or Saibai 09 drugs, open the two ends of the bag and straighten the mouth to form a layer of thick film on the surface of the inoculation block and the base material. And the old fungus removed, that is, bacteria. The fungus can make the buds grow neatly and consistently. The tool used can be made of 8 wire to make a 3 to 4 hook tooth small rake, the surface of the base material smashed, together with the old fungus and seed blocks cleared together, and then the material surface slightly flat, conditional can then Fill with clear water and pour out excess water after 12 hours. To prevent bacterial infection, hand rubbing should be done with alcohol cotton balls before use. 2. Cooling: Low temperature is an important condition for the formation of mushroom buds. After entering the mushroom management, the temperature should be reduced to 7 ~ 13 °C, lower than 7 °C, the long speed is too slow, such as the temperature is higher than 13 °C, there will often be a large number of aerial hyphae on the surface of the base material, affecting the formation of mushroom buds . 3. Humidification: The relative air humidity of the mushrooming site should be maintained between 80% and 85% to induce the formation of mushroom buds. There are many methods for humidification, such as surface irrigation, wall and space spray. 4. Inducing buds: After the above-mentioned management, a few days later, the surface of the base material that has been treated with the fungus bacteria will once again grow a bit of aerial hyphae, and will immediately fall down, and then there will be shallow soy sauce drops of water. This is a mushroom bud. The harbinger of appearance. Soon, beige (or white) mushroom buds will appear neatly on the surface of the base material. The rate of appearance of mushroom bud varies from strain to strain. Some need 2 to 3 days, and some take 10 to 15 days to appear buds. If you delay the appearance of mushrooms, mostly due to the low moisture content of the base material, then the surface of the base material can be sprayed with warm water at 20°C, and the quantity should not be too much. The water spray standard is not suitable for accumulation of water. Second, the temperature Flammulina velutipes is a kind of low-temperature bacteria. The ideal temperature for mushrooming is about 10°C. Under suitable temperature conditions, the fruiting body grows slowly, the color is white (shallow), neat and tender, and the yield is high. If the temperature exceeds 15°C, the fruiting bodies will grow rapidly and the cap will soon open. The stipe will be short and it will be difficult to form the desired mushroom. Also, under high temperature conditions, pests and diseases are prone to occur, affecting yield. The adjustment of the fruiting temperature should be controlled after the bag is budded, cooled to 5 to 8°C, maintained for 3 to 5 days, so that the physiological maturity of the mushrooms is kept as synchronous as possible, so that the mushroom is neat and robust, and the base material is Nutrition can be fully absorbed and utilized. There are two points to note when cooling down: One must cooperate with ventilation and ventilation to reduce the concentration of carbon dioxide and promote the mass production of mushroom buds; The second is that the surface of the base material should not be too wet, and it should be kept in a relatively dry and moist state to prevent the occurrence of frost damage. After low-temperature domestication, the temperature needed for mushroom recovery is maintained at about 10°C, which can effectively promote the growth of fruit bodies. Fixed-point supply supermarkets should control the temperature at 7 ~ 9 °C, not too high. Third, the humidity Flammulina velutipes during the fruiting period, in general, when the bazaar market sells fresh, it should maintain high humidity, mushroom bud formation phase, the relative air humidity should be maintained at about 90%. When the stipe reaches 0.5 cm, it is controlled at about 85%. When the stipe length reaches 1 cm, it is controlled at about 80%. In order to humidify, spray heavy water on the walls and ground, but do not spray water directly on the mushroom body of the bag mouth. When the young mushroom meets water, the mushroom cap will have spots and the base part will turn yellow-brown to brown or brown. The quality of mushroom products. Superfluidity of mushroom body can also cause diseases such as root rot and bacterial scab, especially when the temperature is higher than 15°C, the humidity cannot be higher than 85%. If fresh mushrooms are to be supplied to supermarkets, hotels, or designated units, the humidity conditions should be reduced as much as possible, generally between 70% and 80%, to maximize the shelf life of the products. Fourth, ventilation Theoretically speaking, the fruit body of E. velutipes needs more oxygen during its growth. Therefore, proper ventilation must be maintained. However, our many years of practice has shown that moderate CO2 concentration not only does not affect the growth and development of fruiting bodies, but also helps to improve the quality of mushroom products. For example, when cultivated in underground civil defense works with a depth of 4 meters, During the period of management, such as opening the door, it is not ventilated for the rest of the time. Under conditions of high carbon dioxide concentration, its fruiting bodies are neat, fresh, and light in color (yellow strains), but its base color is darkened, even brown; carbon dioxide concentration Too low, it is not conducive to elongation of the stipe, and easy to open the umbrella cap. Therefore, ventilation regulation should be carried out in stages according to the different development of fruiting bodies. During the budding stage and the growth period of the fruiting bodies, the number of ventilations should be increased and the ventilation volume should be increased. This will allow the formation of more mushroom buds, more uniform mushrooms, and the inability to form needle mushroom. During the mid-growth of fruiting bodies, ventilation should be reduced, and the concentration of carbon dioxide should be increased to 1% to 2%. In the later growth period of fruiting bodies, ventilation should be appropriately controlled to further increase the accumulation of carbon dioxide, thereby obtaining the mushroom products with small caps, long stipe, and uniform thickness. However, it should be noted that when the ventilation is poor, it can induce diseases such as cotton rot. Therefore, proper control should be taken. V. Lighting During fruiting, weak light can be induced, and weak light can promote the formation of fruit bodies, and the light from above can make the fruit body grow in the direction of light, neat and not scattered. Six, remind For products that are sold at a distance or entered supermarkets, the temperature of mushroom management should be controlled at 7 to 9°C, and the air humidity should be 70% to 80%. The fresh mushrooms produced by this management model have a shelf life of about 10 days. And because of low moisture content, normal color, etc., further increase the value of goods.
