DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cultivating a mushroom culture medium in a bottle container to spread mycelia and a mushroom culture container used for the method.

[0002]

2. Description of the Related Art As a culture method of a culture medium used for fungal bed cultivation in facility cultivation of mushrooms, a bag culture method in which a mushroom culture medium is put into a bag provided with a vent (with a filter) to spread hyphae, There is a bin cultivation method to put in. Bag cultivation method is inconvenient because the shape is not fixed,
The present invention relates to a bottle cultivation method which is easy to handle and suitable for mechanization.

As a bottle cultivation method, enokitake is a good example, but it is also applied to oyster mushroom, nameko, bunashimeji, maitake, and the like.

[0004] As for the shape of the bottle used in the conventional bottle cultivation method, a bottle having a cylindrical side surface has been used. The mouth of the bottle is provided with a cap with a filter for ventilation. After inoculation, the culture medium in the bottle is cultured in a culture room in which the temperature and humidity are controlled. In this early stage of culture, hyphal elongation starts from the upper surface of the culture medium close to the aeration filter.

[0005] Although the hypha spreads on the side of the culture medium, the side of the culture medium is in close contact with the side of the bottle, so that the flow of oxygen is not sufficient and the decomposition of the culture medium becomes insufficient. .

[0006]

However, even in a bottle cultivation method which is more convenient to handle than a bag cultivation method, the lower part of the cultivator is immersed in metabolic water generated during the spread of mycelia in the culture medium, and the supply of oxygen becomes insufficient. In addition, there is a problem that the decomposition of the culture medium becomes insufficient, and a problem that various bacteria easily propagate.

[0007] Further, since air is supplied only to the upper surface of the culture medium, after the hyphae spread, the decomposition of the culture medium other than the upper surface becomes insufficient. If the spread of the mycelium and the decomposition of the culture medium are sufficient, the culture medium is reinforced and hardly collapsed. However, there is a problem that the culture medium is weakened at an insufficient portion and the medium is lost during handling. Therefore, an object of the present invention is to provide a cultivation method and a cultivation container capable of sufficiently spreading mycelia on both the upper and lower surfaces and the side surfaces of the culture medium and sufficiently decomposing the culture medium.

[0008]

The cultivation container for mushrooms according to the present invention comprises a cylindrical side surface, a bottom surface, a top surface on which a filter for air circulation is arranged, and an opening / closing opening for taking in / out the culture base. In the cultivation container, the cylindrical side surface is formed as an inverted frustum-shaped side surface having a lower diameter smaller than an upper diameter, and is formed between a top surface on which a filter for air circulation is arranged and a culture medium. When the space is turned upside down,
Means were provided to support the culture medium so that the culture medium did not adhere to the top surface.

[0009] Further, a concave portion for storing metabolic water when the container is turned upside down may be provided in a space formed between the top surface on which the filter for air circulation is arranged and the culture medium.

In the method for cultivating mushrooms according to the present invention, the culture medium is placed in the mushroom cultivation container having the above-described structure, and after sterilization, the inoculum is inoculated.
Invert the top and bottom together with the cultivation container of the present invention containing a culture medium,
The culture medium was separated from the bottom and side surfaces of the cultivation container so that the decomposition of the culture medium was easily promoted.

[0011]

According to the mushroom cultivation container of the present invention having the above structure,
Since the cylindrical side surface is a reverse frustum-shaped side having a smaller diameter at the lower part than the upper part, when the container is turned upside down, the culture medium falls and moves toward the larger diameter top surface. A space is created apart from the side and bottom surfaces. Since air flows through this space, the decomposition of the culture medium is promoted on the side and bottom surfaces.

According to the method for cultivating mushrooms of the present invention,
Put the culture medium in the cultivation container of mushrooms of the above configuration, inoculate the inoculum after sterilization, spread the culture medium in an upright state, and upside down the cultivation container of the present invention containing the culture medium,
Until now, the portion of the culture medium that has been in close contact with the side and bottom surfaces of the cultivation container is separated from the bottom and side surfaces of the cultivation container to form a gap. Then, air circulates over the entire surface of the culture medium, and the hypha decomposes the culture medium uniformly.

[0013] Further, since the metabolic water accumulates in the concave portion, the culture medium is not immersed in the metabolic water, and the flow of air is maintained. Further, since the culture medium is hardened by the protective film, the culture medium is not broken by handling such as taking out from the container.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a mushroom cultivation container and a cultivation method using the container according to the present invention will be described below. FIG. 1 is a side sectional view of an upright state of a mushroom cultivation container of the present invention, FIG.
Is a side sectional view of the cultivation container in an inverted state.

In each of the figures, a cultivation container 1 for mushrooms according to the present invention comprises a storage section 2 for storing a culture medium B and a detachable lid 3 for inserting and removing the culture medium B. The shape of the storage portion 2 is a shape of an open-ended container having an inverted truncated cone-shaped side surface 21 and a bottom surface 22 having a smaller diameter at the lower part than at the upper part.

The lid 3 is provided with a cap 4 having the structure disclosed in Japanese Patent Application No. 3-194949. The cap 4 is provided with a filter 41 made of a nonwoven fabric for allowing air to flow, and through a vent hole 42 having a predetermined sectional area.
The carbon dioxide gas inside is discharged to the outside, and fresh air is supplied from the outside to the inside. Moreover, it is a filter having appropriate dustproofness, moisture retention and air permeability.

A cylindrical support member 31 erected inside the lid 3 has a comb-shaped air flow space 32 formed around the leading edge thereof. Has a recess 33 for storing metabolic water when the container is inverted. In addition, three or more legs 34 are formed on the upper surface of the lid 3 to support and stabilize the weight when similar containers are stacked.

A culture medium B filled in the cultivation container 1 having the above structure.
After the inoculation, a large number of them are arranged in a plane on shelves or the like in a culture room at an appropriate temperature and humidity.
Since fresh air flows from the filter 41 of the cap portion 4 into the inside of the container, mycelia begin to elongate. The carbon dioxide gas generated inside is replaced with air from the filter 41 and discharged to the outside.

Thus, after about 30 days, the mycelium spreads over the entire surface of the culture medium B at a sufficient density. Thereafter, when the cultivation container 1 containing the culture medium B is turned upside down, the portion of the culture medium B that has been in close contact with the side surface 21 and the bottom surface 22 of the storage unit 2 as shown in FIG. , Falls off from the bottom surface 22 and falls on the support member 31 formed on the lid 3.

At this time, the side surface B1 and the bottom surface B2 of the culture medium B
Is separated from the side surface 21 and the bottom surface 22 of the storage unit 2 and the gap 2
Form 3 Then, the air supplied from the filter 41 passes through the air circulation space 32 and the gap 23 and also flows to the side surface B1 and the bottom surface B2 of the culture medium B, thereby promoting the decomposition of the culture medium. Further, the metabolic water generated by the elongation of the hyphae accumulates in the concave portion 33, so that the culture medium B is not immersed in the metabolic water, and the flow of fresh air is maintained.

In this way, the decomposition of the culture medium B proceeds uniformly, and the primordium of the fruiting body starts to form from the mature portion of the infested hypha. When the primordium of the fruiting body begins to be scattered, the culture medium B is taken out from the main cultivation container 1 and grown in a container or the like. The cultivation medium B thus cultivated has a sufficient hyphal spread, and the entire cultivation medium B has a sufficient strength, so that it can be prevented from being damaged by handling.

Further, since the density of the mycelium and the decomposition of the culture medium become uniform, the effect that the spread of the mycelium and the maturation period can be reduced to about 90 days can be obtained. In addition, the cross-sectional shape of the cultivation container of the present invention is not limited to a circular shape. A substantially square cross-sectional shape with rounded corners may be used. It is only necessary that the upper cross-sectional shape be larger than the lower cross-sectional shape in the upright state.

[0023]

As described above, according to the mushroom cultivation container of the present invention, when the container is turned upside down, the side and bottom surfaces of the culture medium are separated from the side and bottom surfaces of the container to create a space. In addition, the mycelium can be sufficiently and uniformly spread not only on the upper surface but also on the side surface and the bottom surface of the culture medium, so that the strength of the whole culture medium is increased and the effect of preventing the culture medium from being easily broken is obtained.

According to the method for cultivating mushrooms of the present invention,
Effective cultivation can be performed by using the cultivation container having the above effects.

In addition, since a concave portion for storing metabolic water generated during the spread of hyphae is provided, an effect is obtained that the culture medium is not immersed in the metabolic water and propagation of various bacteria is prevented. Thus, according to the mushroom cultivation container and method of the present invention, the upper and lower surfaces and the side surfaces of the culture medium can be sufficiently and uniformly decomposed,
The effect is that the harvest can be increased.
