Morchella is generally easy to germinate fruiting bodies under the conditions of low temperature and high humidity, so the growing season of wild Morchella fruiting bodies is generally from March to May or from August to September every year. Studies have shown that the field occurrence conditions of Morchella mainly depend on the precipitation in last year 1 1 month, and the occurrence of Morchella in that year depends on whether the surface soil temperature of 5cm in that spring passes through 1 1.5℃ stably.
Therefore, the occurrence period of Morchella is affected by the annual climatic conditions, and is closely related to the temperature, rainfall and the time of rainfall in the occurrence area. Generally speaking, Morchella usually occurs in the environment where the soil is wet or there is a lot of rainfall and it is easy to keep moisture or the groundwater level is high.
Light can promote the formation of fruiting bodies, and the growth and development of fruiting bodies have phototaxis. Adequate oxygen and well-ventilated places are necessary conditions to ensure the normal growth and development of Morchella.

1, matrix
Can grow on a variety of substrates. It can grow in crops or their by-products left behind that have not been harvested, or in rotten branches, barks and root tissues. ?
2. Temperature
The fungus is a low-temperature fungus, which occurs after rain in March and April, and also occurs at the edge of ditches with running water in August and September. The temperature of mycelium growth is 2 1-24℃, and the temperature of fruiting body formation and development is 5- 16℃. ?
3. Humidity
Relative air relative humidity is generally 65%-85%. ?
4. Soil
Choose loam and sandy mixed soil, and the soil pH value should be 6.5-7.5.
5. Air
The places where wild Morchella occurs are mostly hilly areas or ditches, and the ventilation conditions are excellent. Adequate oxygen is one of the essential conditions for the growth and development of Morchella.
