Morchella cultivation technology: how to artificially cultivate morel?

How to grow Morchella artificially? Please introduce the method Morchella belongs to medium and low temperature fungi, the suitable temperature for mycelial growth is 20-24 ℃, and the suitable temperature for fruiting body development is 15-18 ℃. The temperature difference is large, which is beneficial to the formation of fruiting body. The mycelium does not need light, and the fruiting body needs weak scattered light to grow. Belongs to the aerobic fungus, the carbon dioxide concentration is too high, easy to cause the fruiting body deformity, even rot. The environment pH requires 7.08.0. It can grow in humus, black, brown, yellow loam and sandy loam. The artificial planting method of Morchella can refer to the following: first, the formula of cultivation material: ① sawdust (or cottonseed shell) 75%, wheat bran 20%, phosphate fertilizer 1%, gypsum 1%, humus 3%. ② corncob 20%, sawdust 20%, bean shell 15%, wheat bran 20%, phosphate fertilizer 1%, gypsum 1%, grid 1%, plant ash 2%. The ratio of material to water is 1. 3. Second, clinker cultivation: mix the material well, fill it with 17cm x 33cm polyethylene plastic bag, each bag 500-600g, routine sterilization, inoculation, culture, mycelium full bag after prolonging culture for 5-6 days. 1. Indoor cultivation: after the mushroom room is disinfected, the bed surface is first covered with 3 cm thick humus soil, and the bacterial sticks removed from the plastic bags are arranged one by one, usually 40 in 1 square meter, lightly sprayed with water and covered with soil 3-5 cm, and the surface is covered with 2 cm thick deciduous leaves to keep the soil moist. The air relative humidity is 85% Mak 95%, and the air temperature is 4.4-16 ℃. Generally, fruit bodies can appear in more than one month. 2. Outdoor cultivation: choose the woodland of "3 yang and 7 yin" as the border, the width of the border is 1 meter, the depth is 20-25 cm, the length is not limited, straighten the border, water lightly, sprinkle a layer of lime powder after water infiltration. Take off the bag and discharge the germ stick, the method is the same as above. Pay attention to the temperature change in the border to prevent direct sunlight. Third, raw material cultivation: outdoors, select places with 3 yang and 7 shades, loose and moist soil, and good drainage to make a deep 20-25 cm bed, wet the bottom of the border with water first, spread the mixed culture material on the bottom of the border, flatten it to about 4-5 cm, use 2 kg of bacteria per square meter, break into walnut-sized bacteria, spread evenly on the material surface, and cover a thin layer of fine humus soil; then spread the second layer of material. After sowing, cover with loose humus soil with a thickness of 3-5 cm, cover a layer of broad-leaved leaves, and sprinkle some water appropriately. Fourth, cultivation and management: Morchella is a kind of hygrophilic bacteria, and it is very important to maintain humidity throughout the growing period. Outdoor cultivation, such as more Rain Water, high humidity and suitable temperature, the mycelium grows well, the sclerotia is easy to form, and the fruiting body grows normally. If you encounter drought during the growing period, you should spray water to moisturize at the right time. Late autumn or early spring has a temperature of 4-16 ℃ within a few weeks, which can stimulate the formation of fruiting bodies and normal growth.
