Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method and apparatus for cultivating mushrooms, and more particularly to a method and apparatus for cultivating mushrooms that are almost the same as natural mushrooms through artificial cultivation. It is.

(Conventional techniques and problems) Naturally occurring mushrooms are cultivated in an artificial growth environment, but the cultivated fruit bodies have a shape that is quite different from that of wild mushrooms. ing. In order to make the artificial cultivation environment more similar to nature, it is desirable to introduce sunlight, but since artificial cultivation requires control of temperature, humidity, etc., it is generally not necessary to use a closed space. ,
Since the cultivation is carried out in a heat-insulated cultivation room, providing a window to let sunlight in will impair the heat-insulating seal.

However, in recent years, as a method of introducing sunlight to appropriate locations, a solar collector is installed outdoors, and the sunlight is transmitted indoors from this collector via a light guide such as an optical fiber or optical rondo. A method of guiding is being carried out.

However, it is not possible to obtain mushrooms that are sufficiently close to natural mushrooms by simply introducing sunlight into a closed space where temperature, humidity, etc. can be controlled and irradiating the mushrooms after the bacterial seeding process.

(Means for Solving Problems) That is, the purpose of the present invention is to harvest artificially cultivated mushrooms in a form similar to naturally grown mushrooms, to make the harvesting process easier as there are fewer stones, and to increase the yield. Introduced indoors during the cultivation period after the harvest of mushroom cultivation, it maintains freshness well and produces mushrooms that are not affected by rain, mold, mud, insects, etc. like natural mushrooms and have an excellent appearance. A mushroom cultivation method characterized by intermittently irradiating fruiting bodies with sunlight for a certain period of time, and comprising an adiabatic closed room, a device for introducing sunlight into the sealed room, and an intermittent sunlight irradiation device. The present invention provides a mushroom cultivation device characterized by the following features.

(Example) Hyspizygus marmoreu
s) was inoculated into a cultivation bottle filled with a medium made of sawdust and bran, and the mycelia were cultured in the usual manner.After scraping the outer periphery of the surface, the seeds were introduced from the outside during the 15-day cultivation period. Only visible light with a wavelength of 380 to 700 nm is taken in from sunlight through a filter, the illumination intensity is 200 lux or less, and the irradiation is performed intermittently for a total irradiation time of about 6 hours or more.

In this case, if the irradiation direction is fixed, irradiation will not have a suppressive effect on the shaded areas, so the irradiation direction may be changed or solar reflective materials may be pasted on indoor walls to protect the fruiting bodies of the mushrooms from the surrounding area. Make sure to irradiate evenly.

Next, the mushroom cultivation apparatus will be explained with reference to FIG.

Reference numeral 10 denotes a heat-insulating sealed room, and a sunlight reflecting material 12 is pasted on the inner wall surface.

Reference numeral 14 denotes a shelf on which the cultivation bins 16 are placed, and is made of a net-like board so that sunlight can easily pass through.

Reference numeral 18 denotes a light projector that projects sunlight introduced from a sunlight introduction device 20 provided outside the sealed room 10 toward the fruiting body of the mushroom.

Reference numeral 22 denotes a control box for the light projector 18, which controls the wavelength, illumination intensity, light projection time, etc. of the light, and further oscillates the light projector 18 at a constant rotation angle in the horizontal direction and, if necessary, in the vertical direction.

Therefore, due to the action of the sunlight reflecting material, the fruiting bodies are irradiated uniformly from all angles, and can be irradiated intermittently.

The fruiting bodies of conventionally cultivated Bunashimeji mushrooms when harvested are as follows: (1) The caps are small, thick, dense, and stubby, with black mottled patterns on the surface.

(2) Stones account for 30-40% of the total.

(3) Fruit bodies have a short shelf life of 3 to 4 days, after which time they self-destruct.

On the other hand, in the case of artificial cultivation according to this embodiment, (1) The umbrella is the same as a natural umbrella, and is a so-called medium-high umbrella type with a thin peripheral edge and a raised center.

■ Since there are few stones, there is no need to dig with a spatula when harvesting, and it can be easily picked by hand.

■ The mycelium has good fungal circulation, and the yield is 1% compared to conventional ones.
．． The yield is eight times higher, and if you take into account the fact that there are fewer stones, it can be said that the yield is actually twice as high.

■ It maintains its freshness well and does not deteriorate much even after 5 days. Conventionally, the cultivation environment is kept at around 14°C during cultivation, but in this example, the outside temperature is effectively used within the range of 5°C to 30°C to assist with cooling, humidification, etc. It can be used for specific purposes or made unnecessary.

■ In the case of the believer example, there is no smell of rice bran, and the sugar content is high in taste.

(Effects of the Invention) As described above, in the embodiments of the present invention, mushrooms that are almost the same as natural mushrooms can be reliably and abundantly harvested through artificial cultivation, and they can also be harvested from rain, like natural mushrooms. It is not affected by mold or insects, and does not attract mud or dead leaves, and has excellent commercial value.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
