Key Technical Points for Log Cultivation of Reishi Mushroom (Ganoderma lucidum) in Greenhouses

Technical Introduction: Reishi mushroom (Ganoderma lucidum) grows on broadleaf tree stumps or decaying conifer wood, forming fruiting bodies in summer and autumn. Reishi mushroom is both a saprophytic fungus and a facultative parasitic fungus. The optimum temperature for the growth of Reishi mushroom mycelium is 25°C. The optimum temperature for primordium differentiation and fruiting body development is 25-28°C. During the mycelium growth stage and fruiting body development stage of Reishi mushroom, the suitable moisture content of the substrate is 55-60%; the relative humidity of the air needs to reach 90-95%. Reishi mushroom is an aerobic fungus; when the carbon dioxide concentration in the air exceeds 0.1%, the fruiting bodies of Reishi mushroom will become deformed, or will fail to develop and open their caps. Mycelium growth does not require light; during the process of fruiting body growth and differentiation, more scattered light is needed. Reishi mushroom prefers a pH of 4-5.5. China was the first country to successfully domesticate and cultivate wild Reishi mushroom. In recent years, due to excessive harvesting, wild Reishi mushroom has become increasingly scarce, and artificial cultivation needs improvement and enhanced cultivation methods

The technology of log cultivation of Reishi mushroom in greenhouses is the cultivation of Reishi mushroom using logs in greenhouses. Its process flow is: tree species selection and felling → cutting into sections → sterilization → inoculation → mycelium culture → earthing up → fruiting body management → harvesting and processing.

Core technologies: (1) Selection and felling of tree species; (2) Selection of superior Reishi mushroom strains, strain preservation and strain rejuvenation techniques; (3) Inoculation and mycelium culture techniques for log cultivation of Reishi mushroom; (4) Earthing up of logs and management during the fruiting body development stage; (5) Harvesting of Reishi mushroom spore powder from logs and harvesting and processing techniques for fruiting bodies.

This project makes full use of greenhouses in Beijing, adjusts the planting structure, and by changing the traditional cultivation method of Reishi mushroom, increases yield, meets people's growing demand for Reishi mushroom, and raises farmers' economic income; moreover, Reishi mushroom bonsai can be made to increase added value, which is of great significance for the development of Reishi mushroom production.
