Description

Technical Field

[0001] The utility model relates to the technical field of edible fungus cultivation, in particular to an indoor morel cultivation facility transformed from a tobacco leaf curing house. Background Art

[0002] The existing morel cultivation methods are mainly divided into two categories: field cultivation and indoor cultivation.

[0003] Indoor cultivation is a common method for growing morels, primarily suited to large-scale production. Field cultivation is another common method, primarily suited to areas with favorable natural conditions. While similar to indoor cultivation, the process emphasizes the utilization and regulation of the natural environment. Regardless of the cultivation method, careful control of environmental conditions such as temperature, humidity, light, and ventilation is crucial to ensure proper growth.

[0004] Compared with the above-mentioned morel cultivation method, using tobacco curing houses to grow morels is a new agricultural cultivation model, which can be classified as an indoor cultivation method of morels. However, compared with traditional indoor cultivation, it has the advantages of effectively utilizing resources, improving the utilization rate of land and facilities, and reducing the cultivation cost of morels.

[0005] We know that tobacco curing rooms are usually idle after the tobacco curing period. The growth conditions of indoor morels are similar to those of tobacco curing rooms, such as temperature and humidity. Therefore, it is technically feasible to use tobacco curing rooms to grow morels. In addition, growing morels in tobacco curing rooms can also make full use of the heat preservation and moisture retention properties of the curing room to provide a suitable environment for the growth of morels.

[0006] However, to achieve this goal, existing tobacco curing barns must undergo necessary modifications to accommodate the growth needs of morels. For example, the barn's ventilation system must be adjusted to maintain air circulation and prevent high carbon dioxide concentrations from affecting mycelial growth and fruiting body development. Temperature and humidity control equipment must be installed to maintain a suitable growth environment. Morels have high requirements for temperature and humidity, so the barn's temperature and humidity must be regularly monitored and adjusted to ensure they remain within the appropriate range. Artificial lighting systems must be installed to manage light intensity and ensure the appropriate light intensity for morel growth. Furthermore, pest and disease control, substrate production, and regular substrate replacement are also essential.

[0007] Therefore, using tobacco curing houses to grow morels is an agricultural planting model with broad prospects. Through scientific planning and fine management with appropriate hardware settings, the goal of efficiently utilizing existing resources and improving economic benefits can be achieved.
