Seven key points in the Management of Flammulina velutipes during the Tide transition period

1. Clean the material surface in time. When the fruit body cap is 1.5 cm in diameter and the stalk is 15 cm in length, the residual mushroom feet and small mushrooms on the material surface will be removed immediately after harvest, and the old hyphae on individual material surfaces will be removed to minimize mechanical damage and protect the original mushroom primordium.

2. Properly ventilate and cool down. In the mushroom emergence stage, in order to harvest high-quality Flammulina velutipes with small cover, long stalk, light color and tender, a plastic film is usually covered on the bacteria bag to ensure the humidity needed for the growth of Flammulina velutipes and to create a micro-environment with high carbon dioxide concentration. However, high humidity and high carbon dioxide concentration are not conducive to re-budding, so the film can be ventilated and ventilated in the morning and evening to form primordium as soon as possible and accelerate the turning tide.

3. Give weak scattered light. Flammulina velutipes can form mushroom primordium in dark environment, but the number is far less than that in weak scattered light environment, so it is necessary to give some scattered light when turning tide. The environment of "three points of yang and seven parts of yin" can accelerate the differentiation of mushroom primordium and make it form mushroom buds.

4. Adjust the temperature reasonably. The optimum temperature for the formation of Flammulina velutipes primordium was 13 Mel 15 ℃. If the temperature is on the high side, the amount of spraying water can be increased in the spare space of the mushroom room, and the temperature can be cooled by comprehensive ventilation. It should be noted that the humidity should not be too high when the temperature is high, otherwise it will blacken the mushroom feet, increase the villi, and then cause diseases. If the temperature is on the low side, you can spray hot water or warm the mushroom house to avoid delaying the formation of mushroom primordium due to excessive temperature difference, affecting the growth of mushroom buds and not conducive to turning tide.

5. The water content of culture material should be suitable. The water content of the culture material must reach 65% to 70% in order to ensure its normal growth and smooth tide change in the later stage. If the culture material is dry, you can add more water to the bag at one time. Pour out the excess water after 4 hours, and each bag can be supplemented with 50ml 100ml.

6. Turn around and produce mushrooms. After the second tide mushroom is picked, it should turn around and produce mushrooms at the other end, which can speed up the turning tide, and the yield is equal to that of the first tide mushroom. However, it should be noted that the mycelium is not transparent or there are miscellaneous bacteria infection of the bag should not turn around to produce mushrooms.

7. Prevent mushrooms from coming out all around. Flammulina velutipes cultivated in bags often produce mushrooms on all sides, and there is no or little mushroom in the middle. 20% sawdust can be added to the culture material, which can not only prevent the emergence of mushrooms, but also promote the formation of mushroom primordia.
