Flammulina velutipes is not difficult to cultivate, and it is difficult to improve the yield while ensuring quality. In the case of controlling the environmental conditions, try the following methods to increase production.
Method 1: Change wide bag cultivation to narrow bag cultivation
Many mushroom farmers believe that the use of 25 cm 50 cm plastic bag to cultivate Flammulina velutipes is good, but the wide bag is easy to infect the bacteria, and when the mushroom buds are small, the fruit body is easy to bend, affecting the quality, and the cap is not long and the color is shallow. High quality requirements for tenderness and tenderness. Therefore, it is better to cultivate with a 17 cm 33 cm plastic bag.
Method 2: Change autoclaving to delayed atmospheric sterilization
Flammulina velutipes grows rapidly on culture materials rich in vitamin B1 and vitamin B2, and the amount of powder spores is small, but vitamin B1 is not heat-resistant, and it is easy to decompose rapidly when it is above 120 °C, so the culture material is preferably sterilized by atmospheric 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 the horizontal two-headed mushroom
At the time of loading, the two sides were inoculated and left with a cylinder of about 15 cm, and the pressure was lightly packed to tighten the mouth of the bag. Horizontally placed around 4 layers of bacteria. This method can not only ensure the quality of the mushroom, but also save the mushroom house area, which can increase the output of the mushroom house per square meter by more than 30%.
Method 4: Change the disposable bag to the control bag
Use two-headed closed-type hair culture, if you find that the hyphae grow slowly in the bag, you must unpack the bag in time. However, do not disassemble all of them at this time until the mushroom stem is about 8 cm long and then straighten the straight tube bag to ensure the proper temperature, humidity and carbon dioxide concentration during the mushrooming process. In this process, the mushroom body should be prevented from being bent and growing.
Method 5: Change the growth of the mushroom stem to red light induction
Because the Flammulina velutipes has a strong phototaxis, after the bacteria are put on the shelves, a 15 watt red bulb can be hoisted every 4 meters or so in the middle of the two rows of walls to generate vertical light, which can induce the beam to be directed toward the light source. Cross-section, promote the extension of the mushroom body. However, the doors and windows should be shaded to prevent the mushroom body from being sloppy, lodging and bending.
