When cultivating shiitake mushrooms completely in this way, a shiitake mushroom cultivation device having the structure of the present invention can be used as the fertilization chamber, a shiitake mushroom cultivation device having the structure as described above as the generation chamber, and a shiitake mushroom cultivation device having the structure of the present invention as the curing chamber. Each structured shiitake mushroom cultivation device is used, and first, logs filled with shiitake fungi are placed in a curing chamber for about 6 months to measure the attachment and spread of the shiitake fungi to the logs, and the This involves carving out logs.

This Shiitake fungus takes root on logs indoors (inner house 2).
Maintain the temperature at about 4 to 20 degrees Celsius (optimal temperature 15 degrees Celsius) and the moisture content of the logs to about 37 to 40% or more, and repeat watering and replenishment of fresh air as necessary.
The process is carried out by leaving it for about a month, and in order to prevent the spread of Shiitake fungi onto the logs, the indoor temperature should be kept at about 15-28℃ and the moisture content of the logs should be about 40-55%. Repeated watering and fresh air replenishment depending on the situation, approx.
This is done by leaving the logs alone for several months, and furthermore, the wood is left untreated.
The indoor temperature is maintained at approximately 24-30°C (optimal temperature 28°C) and the moisture content of the logs is approximately 27-45°C, and watering and fresh air are repeatedly added as necessary.
This is done by leaving it alone for about two months.

Next, the wood that has been honed in this way is dried in the hodging room for one month without watering, and forced ventilation is used to reduce the moisture content of the wood to 35% or less. Approximately 8 to 18% in a liquid at approximately 10 to 16°C
Soak for an hour.

Thereafter, this log is placed in a generation chamber for about 4 to 15 days to generate shiitake mushrooms on the log.

At this time, fresh air is replenished into the room (inside the innermost house 8a) by forced ventilation, and water is drained from the surface of the log. The setting is maintained at 50-60%.

The shiitake mushrooms that have developed as described above are harvested as appropriate, and the harvested logs are placed in a curing room for about one month to be cured so that the vitality of the shiitake fungus is restored to the logs.

Immediately sprinkle water on the log to bring the humidity of the log to 50-55.
%, and thereafter watering and replenishing fresh air are performed as necessary, and the temperature of this room (inside the inner house 2) is set and maintained at 24 to 30°C.

This log is then placed in the generation chamber again to generate Shiitake mushrooms in the same manner as above, but in this case, watering is stopped 10 days before the expected generation, and then the logs are immersed in the solution as described above and placed in the generation chamber. I'll bring it back.

Next, management in the vulgarization room, development room, and curing room will be explained.

However, since each of these rooms is managed in almost the same way, the explanation will be given using the barefoot room as an example.

Management in the naked room During winter, all ventilation windows in both the outside and outside houses 1 and 2 are closed, and if necessary, the fan 4 is driven to draw air through the intake duct 3 to replenish fresh air. At the same time, water is sprinkled from the water sprinkler pipe 6 every suitable number of days.

Also, if the outside temperature is particularly low, open the lower ventilation window 2 of the inner house 2.
3.25 is opened and the fan 5 is driven, and from this fan 5 the air layer between the inner and outer houses 1 and 2, the ventilation window 23.2
A winter circulation path is formed that communicates only with the inner house 2 from the air layer through the air layer 5, and the air heated by the air layer is circulated to perform simple heating.

In other words, among the sunlight, visible light and near ultraviolet rays (hormone synthesis rays) necessary for cultivating shiitake mushrooms pass through outer house 1 to inner house 2, but infrared rays and ultraviolet rays (destructive rays) pass through outer house 1. However, since it is reflected by the outer surface of the inner house 2, and this inner infrared ray is a heat conversion wavelength ray, it warms the air layer between the inner and outer houses 1 and 2, and this warmed air By circulating the air into the inner house 2 through the winter circulation passage, simple heating can be performed.

Also, in the summer, the ventilation windows 11, 13 of the outer house 1 are opened, the ventilation windows 21, 23, 25 of the inner house 2 are closed, and the fan 5 is driven as necessary to form a summer exhaust passage. Therefore, the temperature rise inside the inner house 2 can be suppressed.

That is, while the infrared rays of the heat conversion wavelength are reflected on the outer surface of the inner house 2 as described above, natural convection or forced exhaust air flow by the fan 5 is generated in the gap between the inner and outer houses 1 and 2, By taking in air from the lower part of the outer house 1 and discharging it through the upper ventilation window 11, the temperature rise in the inner house 2 can be suppressed. In addition to taking in more air and replenishing fresh air, water is sprinkled from the water sprinkler pipe 6 every appropriate number of days.

Also, when the outside temperature is particularly high during the daytime in summer, fresh air is taken in by driving a fan installed in the exhaust passage that passes through the outside house 1 from inside the inside house 2 and opens to the outside. At the same time, the above-mentioned summer discharge passage is formed, and water is sprayed from the mist nozzle 32, thereby making it possible to perform simple cooling.

That is, this atomized water is drawn into the inner house 2 as it is exhausted by the fan 4, evaporates within the inner house 2, and the interior of the house 2 is cooled by the latent heat of vaporization.

Also, at night in summer, all the ventilation windows of both the inner and outer houses 1 and 2 are opened, and the insides of both houses 1 and 2 are quickly ventilated by natural convection.

In addition, in the interim period, each ventilation window of both the inner and outer houses 1 may be partially opened and the rest closed, or each ventilation window may be left half-open, or fans 4 and 5 may be used in combination to open the inner house as described above. The temperature and humidity inside the chamber are always maintained at optimum conditions.

As explained above, the present invention uses a combination of temperature control based on natural convection inside and outside the house and temperature control based on forced air circulation by fans to always maintain the inside of the inner house under optimal conditions. Moreover, if the temperature inside the inner chamber is adjusted by natural convection, the time required for the adjustment is extremely short, and there is no consumption of electricity, etc., so maintenance costs can be reduced.

Therefore, according to the present invention, temperature can be controlled with a simple structure, so that shiitake mushrooms can be grown at extremely low cost and in a short period of time.
