FIG. 4 is a cross-sectional view showing an example of the form of the fungus bed formed by passing through the continuous fungus scraping process of FIGS. 2 and 3 in the cultivation method of beech shimeji according to the present invention. It is sectional drawing which shows the example of the form of the grown fruit body in the cultivation method of bunashimeji concerning this invention. It is a top view which shows the example of a form of the apparatus (bacteria scraper with a blade) which scrapes the upper surface of a bacteria bed thinly in the fungus scraper used for the cultivation method of bunashimeji concerning this invention. It is sectional drawing which shows the example of the form of the apparatus (pressing tool for fungus bed upper surface formation) which forms the upper surface of a fungus bed in the fungus scraper used for the cultivation method of bunashimeji concerning this invention.

  Hereinafter, the cultivation method of the beech shimeji which concerns on this invention, and the form example of the fungus scraper used therewith are demonstrated in detail based on an accompanying drawing (FIGS. 1-7). According to the present invention, the buna shimeji cultivation method is different from the conventional bun shimeji cultivation method, and the bun shimeji can be produced with higher quality.

  In the beech shimeji cultivation method according to the present invention, as shown in FIG. 1, first, a layer of beech shimeji inoculum 22 is formed on a mushroom culture medium 21 filled and sterilized in a mushroom cultivation bottle 10 having a circular bottle mouth. As described above, the inoculum 22 is put in the mushroom cultivation bottle 10 and inoculated, and the mycelium of Bunashimeji spreads in the mushroom medium 21 to produce the fungus bed 20 in which the inoculum 22 forms an upper layer. And as shown in FIGS. 3-5, the vertical hole 25 is formed in the upper surface center part of the microbial bed 20, and the growth of the mushroom in the site | part in which the vertical hole 25 was provided is characterized by suppressing or preventing.

  According to this, since the vertical hole 25 is formed at the center of the upper surface of the fungus bed 20, the growth of the mushroom (mycelium growth or fruit body growth) in the direction in which the portion is lifted and peeled is suppressed or prevented. Is done. For this reason, the peeling phenomenon of the fungus bed 20 can be prevented, and the fruit body 51 of bunashimeji can be reliably grown.

  Moreover, in this embodiment, the vertical hole 25 formed in the center of the upper surface of the fungus bed 20 is formed by pressing and cutting the fungus bed 20 by a rod-like thrust member as shown in FIGS. The According to this, the hypha of the part where the vertical hole 25 is formed is cut, and the upper surface center part (the upper central part of the inoculum 22) formed of the inoculum 22 is moved to the mushroom medium 21 side. Pressed and pressed and adhered. For this reason, the peeling phenomenon of the microbial bed 20 can be prevented more reliably, and the fruit body 51 of bunashimeji can be reliably grown.

  In addition, as a method of forming the vertical hole 25 in the upper surface center part of the microbial bed 20, it is not limited to this embodiment, For example, the vertical hole 25 is formed also by scraping off or cutting out. Can do. This also makes it possible to substantially eliminate the growth of mushrooms that are intended to lift and peel off the center of the upper surface of the fungus bed 20 and prevent the flaking of the fungus bed 20.

  In addition, as shown in FIG. 2, before the step of forming the vertical hole 25 in the center of the upper surface of the fungus bed 20 (see FIG. 3), the layer of the inoculum 22 is at least layered with respect to the uppermost layer on the upper surface of the fungus bed 20. A step of scraping so as to remain may be performed. In this embodiment, a surface layer portion having a thickness (depth) of the uppermost layer of the fungus bed 20 of about 2 to 3 mm is provided with three blades arranged concentrically as shown in FIGS. When the fungus scraper 40 is rotated, it is a process of thinly removing horizontally.

  According to this, since the surface layer part of the deteriorated microbial bed 20 is appropriately removed, it can be activated as a germination surface, and uniform germination can be promoted. That is, germination occurs in a state where the buds of the fruit bodies 51 are evenly aligned. Moreover, the growth of the fruit body 51 of a mushroom can be accelerated | stimulated, a cultivation period can be shortened and productivity can be improved. Furthermore, since the growth of the fruiting bodies 51 is aligned, the generation of small fruiting bodies is suppressed, and there is also an effect of increasing revenue by increasing the weight of the mushrooms.

  In addition, as a bacteria scraper which removes the surface layer part of the bacteria bed 20 thinly, it is not limited to this embodiment, For example, you may use the bacteria scraper with a blade from which the number of blades differs from this embodiment. Of course. That is, it does not perform a fungus scraping step that prevents germination by roughening the surface of the fungus bed 20, but scrapes the surface of the fungus bed 20 so that it becomes a germination surface that promotes germination. What is necessary is just to use the fungi scratching tool which can do.

  Further, in this embodiment, the peripheral edge portion 26 of the circular upper surface of the fungus bed 20 is scraped, and the upper surface portion of the fungus bed 20 where the fruit bodies 51 are generated is formed in a ring shape. According to this, since it becomes difficult for the mushroom to germinate together with the portion of the vertical hole 25 with respect to the peripheral edge portion 26 that has been scraped off, the range of the upper surface of the fungus bed 20 that can germinate can be limited. According to this, the number and size of the fruit bodies 51 can be balanced with respect to the growth of the mushroom, and the mushroom can be adjusted to grow into a shade of a desired size.

  The step of scraping the peripheral edge 26 on the circular upper surface of the fungus bed 20 prevents the fruiting body 51 from being generated at the peripheral edge 26, and is not limited to this embodiment. That is, as a method of preventing the fruit body 51 from being generated, a method of roughening the upper surface of the fungus bed 20 or a method of rubbing while strongly compressing the upper surface of the fungus bed 20 can be employed.

  Moreover, in this embodiment, the upper surface part where the fruit body 51 of the fungus bed 20 is generated is provided on the convex curved surface 23 as an overall shape by being pressed. This overall shape is the same as that of a conventional manju scraper, and an equivalent effect can be obtained. According to this, an appropriate impact can be given to the upper surface of the fungus bed 20 so as to promote appropriate germination, and appropriate germination can be achieved so as to balance the number and size of the fruit bodies 51. .

Next, the fungus scraper used in the method for cultivating beech shimeji of the present invention will be described.
As shown in FIGS. 3 and 7, the fungus scraper of the present invention has a concave curved surface of the concave curved surface member 31 so that the rod-shaped thrust member 33 forms a vertical hole 25 and a convex curved surface 23 on the upper surface of the bacterial bed 20. 32 is provided with a pressing tool 30 for forming a fungus bed upper surface provided in a shape protruding from 32. The concave curved surface member 31 has a concave curved surface 32 formed like the inner surface of the parabolic antenna as shown in FIGS. 3 and 7 and is in contact with the upper surface of the fungus bed 20 to give a predetermined pressure to the convex curved surface 23. Form. Further, the rod-shaped thrust member 33 in a form protruding on the concave curved surface 32 forms the vertical hole 25 as described above.

  Moreover, according to the fungus scraper of the present invention shown in FIGS. 3 and 7, the peripheral edge 26 can be scraped off simultaneously with the formation of the vertical hole 25 and the convex curved surface 23. That is, the presser 30 for forming the fungus bed upper surface comes into contact with the upper surface of the fungus bed 20 via the biasing force of the pressing spring 34 to form the convex curved surface 23 and the vertical hole 25, and at the same time, the fungus for the periphery. The scraping piece 35 turns and scrapes the peripheral edge portion 26.

Note that the peripheral bacteria scraping piece 35 is arranged so as to be able to turn around the pressing tool 30 for forming the bacteria bed upper surface, and the power transmission member 36 transmits the rotational power of a driving device (not shown) such as an electric motor. It is provided to be.
Further, the inverted mushroom cultivation bottle 10 is held by the guide member 37 into which the bottle mouth fits, and the guide member 37 moves against the urging force of the guide member spring 38, thereby forming the fungus bed upper surface. The pressing tool 30 and the fungus scraping piece 35 for the periphery are configured to gradually come into contact with the fungus bed 20 so as to perform the fungi scraping operation. The pressing spring 34 and the guide member spring 38 according to the present embodiment are configured by coil springs, but are not limited thereto and may be provided by other elastic members.

  The rod-shaped thrust member 33 of the present embodiment has a round bar shape (cylindrical shape) with a circular cross section, and the rod length dimension is larger than the rod diameter dimension. In addition, even if the pointed portion (tapered portion) is removed, the length of the rod is larger than the size of the rod diameter. In this embodiment, the full length dimension of the length of the rod is set to about three times the dimension of the diameter of the rod.

  According to this, since the vertical hole 25 formed in the center part of the upper surface of the fungus bed 20 can be formed in a deep hole, the growth of the mushroom (the growth of the hyphae and the growth of the fruiting body) in the direction of lifting the part. ) Can be more reliably prevented. For this reason, the peeling phenomenon of the microbial bed 20 can be prevented, and the fruit body 51 of bunashimeji can be grown more reliably.

  As shown in FIG. 5, the beech shimeji 50 cultivated by this beech shimeji cultivation method has a recess 53 formed at the center of the end face of the stonework 52. Therefore, it is possible to easily determine whether or not the cultivation method is according to the present invention by inspecting the produced beech shimeji 50.

  Although the present invention has been described with respect to the cultivation method of beech shimeji, it is needless to say that the present invention can also be suitably applied to mushrooms (mushrooms similar to beech shimeji) that have the same properties as bunashimeji and are produced by the same cultivation method.

  As described above, the present invention has been described in various ways with preferred embodiments. However, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
