It is an important link to cultivate Flammulina velutipes at natural temperature and choose suitable production season to obtain high quality and high yield.
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. After the physiological maturity of mycelium, the weather is getting colder and the temperature drops, which is just suitable for the low temperature climate of fruiting body growth and development.
Generally, in the provinces south of the Yangtze River, 1 0 ~1month is used for indirect sowing, and after about1month of fungal culture, the fruit comes into being in1~1February. High altitude and low temperature mountain areas and provinces north of the Yangtze River can be inoculated in September in advance, 1 1 fruiting; You can also inoculate in early spring and heat the mushrooms in spring.
Vaccination should be postponed in low altitude Pingchuan area. In order to meet the market demand of Flammulina velutipes in summer, Flammulina velutipes can be produced in cold storage.
Flammulina velutipes belongs to low-temperature fungi, and the mycelium growth range is 7 ~ 30℃, and the best is 23℃. The adaptive range of fruiting body differentiation and development is 3 ~ 18℃, and 12 ~ 13℃ is the best. When the temperature is lower than 3℃, the bottle cap will turn maltose color and deformed mushrooms will appear.

Fungal growth management
After sowing, at the temperature of 10℃, the mycelium grows all over the material surface and develops to the deep layer in about 15 days. If it is found that some local strains do not germinate after 10, the film can be uncovered for 10 ~ 15 minutes. After about 40 days, hyphae can basically penetrate the material.
When the mycelium of the bed material is completely exposed, uncover the film and ventilate for 10 ~ 20 minutes every day. When the bed surface turns white and amber water drops appear, hold up a 20 cm high plastic film, spread a newspaper on it, and spray it on the newspaper every day to moisturize. Fog particles should be fine, less, even and frequent, so as to keep the newspaper moist. It is not allowed to spray directly on the mushroom bed, otherwise it will easily cause mushroom rot.
Different developmental stages of fruiting bodies need different air relative humidity. When the stem length is 2 cm, the relative humidity of air in the membrane should be kept at 90%, and when the stem length is 10 cm, the water spraying frequency should be reduced to 80% ~ 85%.
During the mushroom growing period, attention should be paid to increasing the ventilation of the mushroom room. When the mushroom grows to 12 ~ 15 cm, it should be harvested in time and the material surface should be cleaned. After drying 1 day, it is necessary to replenish water, cover the film, keep warm and moisturize, and promote the formation of the second mushroom. After picking mushrooms, the management method is the same as before, and mushrooms are picked 3-4 times.
