Flammulina velutipes is not difficult to cultivate, but how difficult it is to increase production while ensuring quality. In the case of good environmental conditions, try the following methods of yield increase.
Method one: Change wide bag cultivation to narrow bag cultivation
Many farmers believe that the use of 25 cm 50 cm plastic bag tube mushroom cultivation is better, but the wide bag is susceptible to bacteria, and when the bud is small, the fruiting body is easy to bend, affect the quality, reach the small handle length, light color The tender quality requirements. Therefore, it is better to use a 17 cm 33 cm plastic bag.
Method two: Change autoclave sterilization to time-delay pressure sterilization
Flammulina grows rapidly on culture materials rich in vitamin B1 and vitamin B2, and the number of powdery spores is small. However, vitamin B1 is not heat-resistant and easily decomposes at temperatures above 120°C. Therefore, the culture materials should be sterilized at normal pressure. However, in order to ensure the pure bacteria rate, the sterilization time can be extended from 10 to 12 hours to 13 to 18 hours.
Method 3: Change the traditional vertical mushroom to horizontal two mushroom
When loading, inoculate two and leave about 15 centimeters of tube membrane, light pressure equalization, tightly close the bag mouth. Horizontal display about 4 layers of bacteria. This method can ensure the quality of mushrooms, but also can save the mushroom room area, can increase the output per square meter of mushroom house more than 30%.
Method 4: Change the one-time solution bag to the control solution bag
Use two closed-end bacteria cultures. If you find that the growth of mycelium in the bag is slow, you must remove the bag in time. But at this time do not untie all, until the mushroom handle grows to about 8 centimeters and then once again straighten the tube bag, in order to ensure the appropriate temperature, humidity and carbon dioxide concentration in the mushrooming process. In this process, the mushroom body should be prevented from being forced to bend and grow.
Method 5: Change the stalk stalk growth to red light induction
Because the mushroom body has a strong phototaxis, after the good bacteria is put on the shelf, it is possible to lift a 15 watt red light bulb every 4 meters above the middle of the two rows of walls to generate vertical light, which can induce the beam to be directed toward the light source. Vigorously promotes the extension of the mushroom body. However, the doors and windows should be shaded so as to prevent the mushroom body from being disordered, lodging and bending.
