Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a shiitake mushroom growing aid for cultivating excellent quality shiitake mushrooms by obscuring shiitake mushroom fruiting bodies that have emerged from hodaki. It is effective for growing high-quality shiitake mushrooms, which have a white cap surface and firm flesh, and are called tempaku don.

[Conventional technology]

Among the shiitake mushrooms obtained during shiitake cultivation, shiitake mushrooms, commonly called "donko", have a rich and firm cap part, and are rich in nutrients such as vitamins _B2 , C, and D (ergosterin), so they have commercial value. Among them, ``Tenpaku Donko,'' which has a white top and a tortoise-like fissure, is prized as a high-quality shiitake mushroom with high added value.

However, Tenpaku Donko can be obtained naturally, but the conditions for its occurrence are early spring (around February to March in warm regions) at temperatures ranging from 5 to 6 degrees Celsius to 17 to 17 degrees Celsius.
Shiitake mushrooms that have sprouted in the 18℃ range (average temperature 12-13℃) are easy to harvest when they grow slowly over 20-30 days, and when the average daytime temperature exceeds 20℃, the legs (stalks)
The skin becomes longer, the flesh becomes softer, and nothing happens.

Therefore, Tenpaku Donko is quite difficult to grow.
There used to be no choice but to harvest shiitake mushrooms under favorable natural environmental conditions, but recently attempts have been made to artificially create these conditions by covering shiitake mushrooms in a near-sealed plastic bag during the early stages of their growth.

[Problem that the invention attempts to solve]

However, when cultivating tenpaku donko in plastic bags, the inside of the bag peels, resulting in soft, blackish shiitake mushrooms, making it difficult to obtain the desired tenpaku donko. There are many problems with cultivation techniques, such as the extremely cumbersome work of hanging bags.

[Means for solving problems]

In view of the current situation, this invention aims to provide a shiitake mushroom growth auxiliary device that can produce as much tenpaku donko as possible by simply and easily artificially creating the natural conditions in which tenpaku donko can be collected. The purpose is to

That is, this invention has a hollow part sufficient to accommodate the cap of the shiitake mushroom fruiting body inside, and
A cover member having an opening at the bottom is formed of a hard or semi-hard material, and a notch groove is provided in a part of the side wall of the cover member that connects to the opening at the bottom, so that the stem of a shiitake mushroom fruiting body that has developed on a tree can be removed. The cap of the shiitake mushroom fruiting body is covered by the hollow part of the cover member by fitting the part into the notch groove.

[Effect]

As shown in FIG. 1, the shiitake mushroom growth aid 1 of this invention has a hollow part 2 inside, the top part is closed, and an opening 3 is formed in the lower part of the cover member 1.The side wall of the cover member 1 has an opening 3 connected to the opening 3. A cutout groove 4 is provided.

Therefore, in use, as shown in FIG. 2, the cutout groove 4 of the cover member 1 is fitted into the stalk 8 of the initial shiitake mushroom fruiting body that has developed from the hodagi 9, and the shiitake mushroom is then grown. With the actual umbrella portion 7 positioned at the center of the hollow portion 2, the cover member 1 is secured with a nail 10 using the locking hole 6 of the locking piece 5 provided in the cover member 1. It is to be fixed to a tree 9.

In this way, when the fruiting body of a shiitake mushroom in its early stage of development is covered with this cover member 1 and the fruiting body of the shiitake mushroom grows to about the size of a thumb, this cover member 1 is removed and the fruiting body of the shiitake mushroom is then covered with the cover member 1 as shown in Fig. 3. Using the cover member 11, similarly, as shown in FIG.

In this case, the cover member 11 is held in a state where it is hooked onto the stem 8 of the shiitake mushroom.

In this way, by covering the shiitake mushroom with the cover member, the umbrella part 7 of the shiitake mushroom is protected from rainwater, the shiitake mushroom is protected from being blown away by strong winds, and the bottom opening 3 and the cutout part 4 are protected. Since proper ventilation is carried out from the inside, the inside of the hollow part 2 is kept at a suitable temperature and humidity, thereby allowing the cap part 7 to grow into a dense fleshy substance, resulting in Tenpaku Donko.

In addition, when explaining the use, we used two types of cover members 1 and 11, large and small, but from the beginning we used the large cover member to grow the shiitake mushroom fruiting body, and it was hoped that it would generate tenpaku donko. However, in that case, it is necessary to provide a hook piece on the cover member 11 in advance to protect the handle part which is in the process of growing.

〔Example〕

Hereinafter, embodiments of this invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 shows an example of the shiitake mushroom growth aid of this invention. The cover member 1 constituting the shiitake mushroom growth aid has a cylindrical shape as a whole, has a hollow part 2 inside, and is closed at the top. At the same time, the bottom part is opened over the entire surface to form an opening 3, and a notch groove 4 is formed in a part of the side surface, continuous with the opening 3 in the bottom part.
A locking piece 5 having a locking hole 6 formed in the upper part of the side wall connected to the notch 4 and connected to the side wall.
It is a projecting structure.

The cover member 1 is made of plastic or glass;
Alternatively, the cover member 1 may be made of a hard or semi-hard material such as waterproofed cardboard, and the cover member 1 may be transparent (including colored transparent) or opaque.

The size of the hollow part 2 is such that it accommodates the initial cap (thumb-sized) of a shiitake mushroom that develops on a tree as a fruiting body, and when the cap grows and expands at the harvesting time. Specifically, the cover member 1 has a diameter of approximately 70 to 90 mm.
The diameter is about φ and the height is about 30 to 50 mm.

The notch 4 is large enough to pass through the stem portion of the shiitake mushroom that has extended beyond the hodaki, and has a size that is the size of the stem from the early stage of elongation beyond the hodaki up to the time of collection. It is of a size that allows for sufficient interposition of the

In the embodiment shown in FIG. 3, the cover member 11 has a spherical top portion to improve light condensation, has a hollow portion 12 inside, and an opening 13 at the bottom.
and has a notched groove 14 connected to the opening in the side wall, and has a diameter of 90 mmφ and a height of 50 mm.
belongs to.

As described above, these cover members 1 and 11 are placed over the shiitake mushroom fruiting bodies that have developed on the wood, and by covering the entire body, the growth of excellent quality shiitake mushrooms can be achieved.

[Effect of idea]

The shiitake mushroom growth auxiliary device of this invention consists of a cover member having an opening at the bottom and a notched groove connected to the opening at the side wall. By covering the cap of the shiitake mushroom with water, the cap is protected from rainwater, and the cap is provided with appropriate temperature, humidity, and ventilation, thereby artificially creating the natural conditions for obtaining tenpaku donko. We cultivate Shiitake mushrooms of excellent quality, which are thick and have white fissures on the top of their caps.
It is something that can be harvested.

Furthermore, the shiitake mushroom growth aid of this invention provides overall strength by forming the cover member with a hard or semi-hard material, and prevents the cover member from coming into contact with the internal umbrella part due to wind. In addition, by allowing the cover member to be hung on the wood, it is prevented from being blown away, and the work of attaching the cover member is facilitated.

In addition, by covering the shiitake mushroom fruiting bodies that have developed from hodaki trees during the cold season, it is possible to prevent the shiitake mushroom fruiting bodies from dying, further increasing the production of shiitake mushrooms. It is highly practical in that it can be used repeatedly, and it is possible to reliably obtain shiitake mushrooms of excellent quality at a low cost.
