During the cultivation process, we should pay attention to the change of humidity. If there is too much water, the mycelium grows slowly and cannot grow into the substrate. When it grows in solid, it is not suitable to spray water directly, because if the humidity is too high, the pollution rate will increase. Flammulina velutipes in the formation period, the stem is shorter, and the umbrella opens faster.

Flammulina velutipes is an aerobic fungus of Flammulina velutipes. It must have enough oxygen to produce mushrooms, otherwise it can't produce mushrooms normally. After the fruiting body was formed, the diameter of fungi decreased with the increase of indoor carbon dioxide concentration. Therefore, in the cultivation process of Flammulina velutipes, we must strengthen ventilation to ensure adequate oxygen.

Artificial cultivation should be selected according to the local natural temperature. Inoculation in late autumn in the south and mid-autumn in the north can make full use of natural temperature to cultivate mycelium fungi. After the mycelium matures physically, the weather becomes cold and the temperature drops, which is suitable for the growth and development of fruiting bodies in low temperature climate. In jiangnan province, mushrooms are usually planted indirectly from June 10 to June10, and can be inoculated in early spring. Warm-haired mushrooms produce mushrooms in spring. Vaccination should be delayed in low altitude areas of Pingchuan. In order to meet the market demand of Flammulina velutipes in summer, Flammulina velutipes can be produced in cold storage.

Untie the openings at both ends of the bag and roll the excess plastic bag onto the surface of the material. One or both ends of the bag can be determined according to the length of the bag. One end of the bag should be put together, and the bottoms of the two bags should be relatively flat. Spray enough water on the ground and around the site, and then cover the bag with plastic film. This method has good heat preservation and moisture retention, and can accumulate carbon dioxide in the future, which is beneficial to the growth of straw.

The water content of Pleurotus eryngii is too high, and the mycelium grows slowly, even unable to extend to the substrate. However, because Pleurotus eryngii can not be sprayed on the fruiting body, excessive humidity will increase the pollution rate of the filter bottle. Flammulina velutipes is an aerobic fungus, and it must have enough oxygen to produce mushrooms. After the fruiting body is formed, the diameter of the cap decreases with the increase of carbon dioxide concentration.
