Scope

Main Technical Content: 3.1 Morels Morels (Morchella spp.) belong to the Ascomycota phylum, Pezizomycetes order, Pezizales family, and Morchellaceae genus. They are also known as Maogu, Mazi, Langzi, Tianlangzi, Mishai, Yangducai, Yangdumu, Yangduzi, Yangque, Yangque Moth, etc. 3.2 Master Seed A pure culture of mycelium derived from the transplantation and expansion cultivation of parental strains, also known as secondary seed. 3.3 Cultivation Seed A pure culture of mycelium derived from the transplantation and expansion cultivation of master seed. Cultivation seed can only be used for cultivation and cannot be used for further strain expansion. Also known as tertiary seed. 4. Production Conditions for Cultivation Seed The selection of production sites, plant layout, and equipment must comply with the requirements of NY/T 528 and NY/T 2375. 4.1 Selection of Morel Master Seed Morel master seed should be purchased from qualified units and transported at ≤4°C. It should be inoculated as soon as possible after receiving the seed. The variety and source quality of the seed must meet the requirements of NY/T 528. 4.2 Temperature in the Inoculation Room During the cultivation of morel cultivation seed, the environmental temperature should be controlled at ≤14°C. 4.3 Cultivation Conditions for Morel Cultivation Seed The cultivation environment temperature should be controlled at 12–14°C and maintained at a constant temperature. The humidity of the cultivation room should be controlled at 80–85%. 5. Methods for Cultivation Seed Production 5.1 Selection of Sowing Time The suitable sowing period is October–December. Cultivation seed should be produced 10 days before sowing, and sowing should be carried out when the ground temperature is stable at 5–16°C. 5.2 Cultivation Seed Production 5.2.1 Formulation and Pre-Processing Methods for Cultivation Seed Substrate 60% wheat grain, 37% corn cob, 3% gypsum. The wheat grain and corn cob should
