Cultivation techniques of Flammulina velutipes: how to cultivate Flammulina velutipes with high yield?

How to cultivate Flammulina velutipes with high yield? Is there any good way? Also ask experienced netizens to help introduce several methods to increase the yield of Flammulina velutipes in the farming network, which are listed below for netizens' reference. Method 1. Change wide bag cultivation to narrow bag cultivation. The wide bag is easy to be infected with miscellaneous bacteria, and when the mushroom buds are few, the fruiting body is easy to bend, which affects the quality, which can not meet the high quality requirements of long handle, light color and tender. Therefore, it is better to cultivate it with a plastic bag of 17% × 33 cm. Method 2. The sterilization method was changed from atmospheric pressure to high pressure sterilization. On the culture medium rich in vitamin B1 and B2, it grew rapidly and the number of pollen spores was less. But vitamin B1 is not heat-resistant, and it is easy to decompose quickly when it is above 120 degrees Celsius, so it is better to sterilize under atmospheric pressure. However, in order to ensure the pure bacteria rate, the sterilization time can be extended from 10-12 hours to 13-18 hours. Method 3. Change the traditional vertical mushroom production to horizontal mushroom production at both ends, inoculate at both ends and leave a tube film of about 15 cm each, light and uniform pressure, and fasten the mouth of the bag. Put about 4 layers of bacteria horizontally. This method can not only ensure the quality of mushroom production, but also save the area of mushroom room, and increase the output of mushroom house by more than 30% per square meter. Method 4. In order to control the closed culture of bacteria at both ends of the bag, due to the low concentration of oxygen in the bag, the growth of the bag will be affected if the mycelia spit out yellow beads according to the conventional method. Therefore, it is necessary to pay attention to the mycelium growth in the bag at any time, and once it is found that the mycelium in the bag grows slowly, it is necessary to unpack the bag in time. But do not stretch it all at this time, until the stalk grows to about 8 cm, and then straighten the bag at one time to ensure the appropriate temperature, humidity and carbon dioxide concentration in the process of mushroom production. In this process, the mushroom body should be prevented from being forced to bend. Method 5. The Flammulina velutipes body has a strong phototaxis, so after the bacteria are put on the shelf, a 15-watt red light bulb can be hoisted at the middle of the two rows of walls every 4 meters or so to produce vertical light, which can induce it to grow horizontally toward the light source and promote the mushroom body to extend. But at this time, the doors and windows should be shaded to prevent the mushroom body from growing, lodging and bending. Method 6. Many mushroom farmers know that adding growth regulators and other nutrients can promote the growth of Flammulina velutipes, but the effect is not obvious or even inhibit the growth of Flammulina velutipes. Practice has proved that the mixture of 0.5% triacontanol and 10 ml gibberellin per kilogram of water can increase the yield by more than 17%, but special attention should be paid to the concentration.
