The proper cultivation and management techniques of Flammulina velutipes determine the yield and quality of Flammulina velutipes: 1. Change wide-bag cultivation to narrow-bag cultivation Many people think that it is better to use 25 cm 50 cm plastic bags to cultivate Flammulina. However, in fact, the wide-bag is easy to infect the bacteria, and the fruiting body is easy to bend when the bud is too small, which affects the product quality, and does not meet the requirements of small cover, long handle, light color, and fat tenderness. Therefore, it is better to use a 17 cm 33 cm plastic bag. 2, change the autoclave to delay atmospheric pressure sterilization Flammulina velutipes grows faster on cultures rich in vitamin B1 and vitamin B2, and has fewer spores. However, vitamin B1 is not heat-resistant and easily decomposes when the temperature reaches 120°C. Therefore, the culture medium should be sterilized at normal pressure. In order to ensure that bacteria do not infect bacteria, sterilization time can be extended from 10 to 12 hours to 13 to 18 hours. 3, change the traditional vertical mushroom for horizontal two mushroom After loading, inoculate plastic bags at both ends and leave about 15 cm of plastic film. Lightly press lightly, and then tie the bag horizontally to display 4 layers of bacteria. This method can not only guarantee the quality of mushroom, but also can save the area of ​​mushroom house, and can increase the output of mushroom house per square meter by more than 70%. 4, to change a one-time solution bag to control bag For the two-headed closed strain culture, because the oxygen concentration in the bag is low, if the mycelium grows and matures and the yellow ball is spit out, it will inevitably affect its growth. Therefore, we must always pay attention to the growth of mycelium in the bag. Once the mycelium grows slowly, we must remove the bag in time. But at this time, do not fully open the bag mouth, should be opened as appropriate, slowly open the bag mouth, wait until the mushroom handle grows to about 8 cm and then open the bag mouth, in order to ensure the mushroom body temperature required during the process, Humidity and oxygen concentration. In this process, the mushroom body should be prevented from bending and growing. 5. Releasing any mushroom handle elongation to weak red light induced The mushroom body has a strong phototaxis, so after the fungus bag is put on the shelf, a 15-watt red light bulb can be hoisted every 4 meters above the center of the two rows of walls. The filaments bunched in the direction of light. But at this time, the doors and windows should be shaded so as to prevent the mushroom body from being disordered, lodging and bending. 6, change the mushroom period of random nutrition and scientific application Many farmers need to apply growth regulators and other nutrients during the fruiting period in order to promote the growth of the mushroom body, but often the effect is not obvious and even inhibits the growth of the mushroom body. It has been proved that the spraying of a triacontanol solution with a concentration of 0.5% at the fruiting stage can increase the yield by more than 17%, but special attention should be paid to the concentration. After the two-stage mushroom is harvested, a 500- to 1000-fold diluted manure water is injected into the bag, which can increase production by 15% to 20%.
