Description

Detailed Description of the Invention

[0001]

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

[0002]

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

[0003] Enoki mushrooms are a good example of bottle cultivation method, but in addition to that, oyster mushrooms, nameko, beech shimeji mushrooms, maitake mushrooms, etc. are also applied.

As the bottle container used in the conventional bottle cultivation method, a bottle container having a cylindrical side surface has been used. The mouth of the bottle is provided with a cap having a filter for ventilation. After inoculation, the culture medium in the bottle container is cultured in a culture room where the temperature and humidity are controlled. In the first half of this culture, hyphae start to grow from the upper surface of the culture medium near the aeration filter.

The mycelium also spreads to the side surface of the culture medium, but since the side surface of the culture medium is in close contact with the side surface of the bottle container, oxygen is not sufficiently distributed and the decomposition of the culture medium becomes insufficient. .

[0006]

However, even in the bottle cultivation method, which is easier to handle than the bag cultivation method, the lower part of the cultivation device is soaked in the metabolized water generated during the process of infestation of the hypha in the culture medium, resulting in insufficient oxygen supply. However, there are problems that the decomposition of the culture medium becomes insufficient and that various bacteria easily propagate.

Further, since air is supplied only to the upper surface of the culture medium, the decomposition of the culture medium becomes insufficient except for the upper surface after the mycelium has spread. If the mycelium spreads sufficiently and the culture medium is sufficiently decomposed, the culture medium is reinforced so that the culture medium is less likely to collapse, but there is also a problem that the culture medium becomes weak at the insufficient portion and the culture medium is lost during handling. Therefore, an object of the present invention is to provide a cultivation method and a cultivation container in which the mycelia can be sufficiently spread on both the upper and lower surfaces and the side surfaces of the culture medium to sufficiently decompose the culture medium.

[0008]

The mushroom cultivating container of 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 port for inserting and removing the culture medium. In the cultivation container formed as described above, the tubular side surface is formed into an inverted frustum-shaped side surface in which the diameter of the lower portion is smaller than the diameter of the upper portion, and is formed between the top surface on which the filter for air circulation is arranged and the culture medium. When you turn the top and bottom of the container into space,
A means for supporting the culture medium so as not to adhere to the top surface was provided.

In addition, a recess formed in the space formed between the top surface on which the air-flow filter is arranged and the culture medium may be provided with a reservoir for storing the metabolized water when the container is turned upside down.

In the method of cultivating mushrooms of the present invention, the culture medium is placed in the container for cultivating mushrooms having the above-mentioned constitution, and after sterilization, the inoculum is inoculated, and the culture medium is spread upright in the upright state.
Invert the top and bottom together with the cultivation container of the present invention containing the 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 cultivating container of the present invention having the above structure,
Since the cylindrical side surface is a side surface of an inverted frustum shape in which the diameter of the lower portion is smaller than the diameter of the upper portion, when the top and bottom of the container are inverted, the culture medium falls and moves toward the top surface having the larger diameter, A space is created apart from the side surface and the bottom surface. Since air flows through this space, the decomposition of the culture medium is promoted also on the side surface and the bottom surface.

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, infest the culture medium in an upright state, and then flip the top and bottom together with the cultivation container of the present invention containing the culture medium,
The part of the culture medium that has been in close contact with the side and bottom surfaces of the cultivation container until now 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 mycelia uniformly decompose the culture medium.

Further, since the metabolized water accumulates in the recesses, the culture medium is not submerged in the metabolized water and air circulation is maintained. Further, since the culture medium is hardened by the protective film, it does not collapse due to handling such as removal from the container.

[0014]

[Examples] Hereinafter, examples of a container for cultivating mushrooms of the present invention and an example of a cultivation method using the container will be described. FIG. 1 is a side sectional view of the mushroom cultivating container of the present invention in an upright state, FIG.
FIG. 3 is a side sectional view of the cultivation container in an inverted state.

In each drawing, a mushroom cultivation container 1 according to the present invention comprises a storage part 2 for storing a culture medium B and a removable lid part 3 for putting the culture medium B in and out. The shape of the accommodating portion 2 is the shape of an open container including an inverted frustoconical side surface 21 and a bottom surface 22 having a smaller diameter in the lower portion than in the upper portion.

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

An air circulation space 32, which is cut in a comb-like shape, is formed in the peripheral portion of the leading edge of the cylindrical supporting member 31 which is erected inside the lid 3, and is formed outside the cylindrical supporting member 31. Has a recess 33 for storing the metabolized water when the container is inverted. Further, on the upper surface of the lid 3, three or more legs 34 are formed for supporting and stabilizing the weight when stacking similar containers.

Culture medium B filled in the culture container 1 having the above-mentioned structure
After inoculating the plants, a large number of them are arranged in a plane on the shelves in the culture room at an appropriate temperature and humidity, and further stacked in several stages in the vertical direction.
Since fresh air circulates from the filter 41 of the cap portion 4 into the inside of the container, the mycelium begins to grow. The carbon dioxide gas generated inside replaces the air from the filter 41 and is discharged to the outside.

In this manner, after about 30 days, the mycelium spreads over the entire surface of the culture medium B at a sufficient density. Then, when the top and bottom of the cultivation container 1 containing the culture medium B is turned upside down, the portion of the culture medium B which has been in close contact with the side surface 21 and the bottom surface 22 of the storage unit 2 until now is stored in the storage unit 2 as shown in FIG. It detaches from the bottom surface 22 and falls, and rides 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 are
Is separated from the side surface 21 and the bottom surface 22 of the storage section 2 and is separated by the gap 2
3 is formed. Then, the air supplied from the filter 41 also flows through the air circulation space 32 and the gap 23 to the side surface B1 and the bottom surface B2 of the culture medium B to promote the decomposition of the culture medium. In addition, since the metabolized water generated by the elongation of the hyphae collects in the recess 33, the culture medium B is not submerged in the metabolized water, and the fresh air is kept flowing.

In this way, the decomposition of the culture medium B proceeds uniformly, and the primordia of the fruiting body begin to be formed from the mature part of the infested hyphae. When the primordia of the fruiting bodies start to be scattered, the culture medium B is taken out from the main cultivation container 1 and arranged in a container or the like for growth. In the culture medium B thus cultivated, the hyphae are sufficiently spread, and the culture medium B as a whole has sufficient strength, so that it can be prevented from being damaged by handling.

Further, since the density of the hyphae and the decomposition of the culture medium become uniform, the infestation and aging period of the hyphae can be shortened to about 90 days. The cross-sectional shape of the cultivation container of the present invention is not limited to a circle. It may have a substantially rectangular cross section with rounded corners. It is only necessary that the upper cross-sectional shape is 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 surface and the bottom surface of the culture medium are separated from the side surface and the bottom surface of the container to form a space. As a result, the hyphae can be sufficiently and evenly spread not only on the upper surface of the culture medium but also on the side surfaces and the bottom surface of the culture medium, and the strength of the entire culture medium is increased, which makes it difficult to cause loss.

According to the method for cultivating mushrooms of the present invention,
Effective cultivation can be carried out using a cultivation container that achieves the above effects.

Further, since the concave portion for accommodating the metabolized water generated during the hyphae infestation process is provided, the culture medium is not soaked in the metabolized water and the effect of preventing the growth of various bacteria can be obtained. 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 yield can be increased.
