Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for cultivating a shiitake mushroom bed and an apparatus therefor;
In particular, the present invention relates to a method and apparatus for cultivating a shiitake mushroom bed, which is suitable for shortening the ripening period in culturing the fungus bed, and improving the efficiency of development and harvesting of fruiting bodies.

[Conventional technology] Shiitake mushroom logs are cultivated by using logs of broad-leaved trees such as oak and oak, and cutting them into pieces of about 1 meter in length, which are convenient for handling, and planting shiitake mushroom inoculum on so-called hodagi. Place the mushrooms under a forest or artificial shade to allow the mycelium of the shiitake mushrooms to grow on the logs. If this was done, shiitake mushrooms would grow on the logs in the second year and could be harvested.

Recently, there has been a shortage of logs for bare wood.

Instead of log cultivation, container cultivation (bag cultivation, bottle cultivation) using fungal beds mainly made of broad-leaved sawdust has begun to be practiced.

That is, a medium is prepared by mixing sawdust from a broad-leaved tree such as oak or oak, nutrient bodies such as rice bran, and water, and the medium is packed in a heat-resistant bag or a polypropylene bottle and sealed with a filter cap. High-pressure sterilization of bacteria in the culture medium,
Inoculum is inoculated into a culture medium in a clean inoculation chamber, and the medium inoculated with the inoculum, that is, the bacterial bed, is cultured in the culture chamber.

[Problems to be Solved by the Invention] When culturing shiitake mushrooms in containers using a fungal bed mainly made of broad-leaved sawdust, as in the prior art described above, the cultivation period for shiitake mushrooms is about 3 months compared to other mushrooms grown on fungal beds. The problem was that it was long.

In addition, when fruiting bodies are generated, the fungal bed is taken out from a bag, etc., so the fruiting bodies are generated from the top and sides of the fungal bed.
There was a problem in that it took time to harvest.

The present invention has been made in order to solve the problems of the prior art described above, and is a method for cultivating shiitake mushroom beds that can shorten the ripening period in the culture process and improve the efficiency of fruiting body development and harvesting operations. The object of the present invention is to provide a device for the same.

[Means for Solving the 11 Problems] In order to achieve the above objective, the structure of the method for cultivating a bed of shiitake mushrooms in which 41 tubes are produced is to inoculate a culture medium with a seed fungus and cultivate the bed of shiitake mushrooms. In the bed cultivation method, 1. A cultivation bed consisting of at least a surface with a removable transparent plate and a light-shielding surface, which can be rotated vertically and horizontally, is provided, and a medium inoculated with seed bacteria is packed in a container to perform the first cultivation. The culture is stirred, and then the bacterial bed that has been stirred is stored from the container into a cultivation bed, and the surface of the cultivation bed with the transparent plate is oriented vertically to face the lighting means for secondary cultivation. After ripening, a germination treatment is performed at low temperature, and the transparent plate is removed with the transparent plate of the cultivation bed facing upward to allow fruiting bodies to develop and grow.

In addition, in order to achieve the above object, the structure of the Shiitake mushroom bed cultivation device according to the present invention is such that the Shiitake mushroom bed cultivation device inoculates a culture medium with a seed fungus and cultivates the fungus bed. A container filled with a medium and used for stirring the primary culture;

As shown in FIG. 3, the cultivation bed 2 that has been subjected to the generation operation is constructed by rotating the bed section 21 in the horizontal direction and removing the transparent plate 21a.
face upward and remove the transparent plate 21a. Then, the length of the support column 22 is individually adjusted to a plurality of levels, for example,
The fruiting bodies 10 are arranged as shown in Figure (b) to form a process of generation and growth.

In the generation/growth room, the illuminance is 5012ux or more, and the temperature is 18~
The fruiting bodies 10 are grown and harvested under controlled environmental conditions of 25° C. and a temperature of around 85%.

After harvesting, the support column 22 is removed from the cultivation bed 2, and the fungus bed is allowed to rest for about 20 days under the same conditions for generation and growth.Then, the fungus bed is submerged in a water tank with the bed intact, and the fruiting bodies are removed. to occur. This operation allows for about three occurrences.

According to this embodiment, the bacterial bed can be uniformly exposed to specific light, and the ripening period can be shortened by 5 to 10 days compared to the conventional method. Also, fruiting bodies develop on certain sides of the bed. Furthermore, after the second culture, the fungal bed can be moved in bed units, so
