DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for artificially cultivating matsutake mushrooms.

[0002]

2. Description of the Related Art Conventionally, as a method for artificially cultivating matsutake mushrooms, methods such as sowing spores of matsutake mushrooms in the forest or inoculating the culture mycelia into the ground have been tried, but the success rate is extremely low, and in reality, artificial matsutake mushrooms are used. There is no cultivation method.

[0003]

From the viewpoint of botany, matsutake mushrooms belonging to fungi have a special relationship with Akamatsu. The vegetative mycelium of matsutake mushrooms infiltrate underground, creating so-called whites. A lot of red pine fine roots enter into this white to form ectomycorrhizal fungi. Ectomycorrhiza is thicker than ordinary roots and is branched in a coral shape.The surface of the mycorrhiza is densely wrapped with pine mushroom hyphae. Not inside. The mycelium physiologically plays the role of root hair and serves to absorb water and nutrients, especially nitrogen and phosphorus. As a result, it is considered that Akamatsu supplements the nutrition of the pine tree, and instead, the hyphae live by living in the roots to obtain carbohydrates and other substances. The hyphae breathe air, so they grow in shallow soil and do not attach to the roots of red pine in deep soil. That is, matsutake mushrooms are easily generated in a thin and thin red pine forest with a surface soil of 10 cm or less with granite, quartz trachyte, quartz porphyry, sandstone, hornstone, etc. as the host rock. As described above, pine mushroom hyphae are organically combined with living red pine roots, and cannot be artificially cultivated as easily as shiitake and enoki mushrooms. This led to a further decrease in the production of matsutake mushrooms and made artificial cultivation of matsutake mushrooms impossible.

Accordingly, an object of the present invention is to provide a method for artificially cultivating Matsutake mushrooms regardless of the season by artificially culturing and collecting spores.

[0005]

In order to achieve the above object, in the method for artificially cultivating Matsutake mushrooms of the present invention, starch and a suitable amount of water are added to and mixed with sterilized red pine wood chips and rice bran, and the mixture is mixed. Put in a bottomed bag made of airtight material,
A matsutake mushroom is planted in the mixture, the spores are allowed to fall for a certain period of time in a constant temperature environment of about 29 to 32 ° C. in a state where the bottomed bag is sealed, and the spores are taken out from the bottomed bag. It is sown on a well-ventilated soil with 40% sunlight and 60% shade.

Further, after the spores are dropped on the mixture in the bag, the spores are stored in a temperature environment of 18 ° C. or lower, and the spores are taken out from the bag when necessary, and the sunlight is 40% and the shade is 60%.
When sown in well-ventilated soil, you can grow matsutake mushrooms regardless of the season.

Further, when spores are sown on the soil, an arc-shaped depression is formed on the ground surface when viewed from a plane, and spores of matsutake mushrooms are sown in the depressions. Covering with spores is preferred because the spores do not die.

[0008]

[Action] The fungi of pine mushrooms enter the intercellular spaces of the fine roots of Akamatsu and have the property of symbiosis with Akamatsu, and therefore use the wood chips of Akamatsu.

Since matsutake does not perform any photosynthesis and absorbs all nutrients and water from the mycelium, it is made by mixing rice bran, starch, and water as nutrients and water with red pine wood chips.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

5 kg of red pine sawdust that has been steam-sterilized is mixed with 5 kg of rice bran that has been steam-sterilized, 3 kg of flour that has not been steam-sterilized, and water that has been boiled and cooled to room temperature. The amount of water may be such that the mixture does not drip. As shown in FIG. 1, the mixture 2 is put in a bottomed bag 1 made of an airtight member, and matsutake mushrooms 3 are planted in the mixture 2 to close the upper opening of the bottomed bag 1. In this state, the spores 4 that had fallen and deposited on the mixture were taken out of the bag for about 48 hours in an insulated box heated to a temperature of about 30 ° C., and the soil where Akamatsu had grown or the rock mountain of Akamatsu forest, An arc-shaped depression 5 is formed in the soil of the stone mountain, and after the spores 4 are sown in the depression 5, as shown in FIG.
It is covered with. The best season to sow 4 spores is in the early summer before the rainy season, with 40% sunlight and 60% shade in the sowing place.
Good location. In places where the sunshine is 70% or more, spores of Matsutake mushrooms belonging to fungi die and do not reproduce.

It is difficult to collect all the spores 4 deposited on the mixture 2 from the mixture 2, and if the spores are not stored in the mixture 2 under a temperature environment of 18 ° C. or lower, the spores will not be killed and any spores will not be killed. It can be taken out and cultivated at appropriate times.

In this embodiment, the sterilization treatment is performed on the sawdust, rice bran and water in order to prevent the growth of microorganisms adhering to the sawdust and the like while keeping the temperature in a sealed state. The pine mushroom hyphae breathes air, but the amount of oxygen in the bag 1 is sufficient to breathe air for about 48 hours. Matsutake mushrooms are allowed to stand in a temperature environment of about 30 ° C. because they have a property of falling spores at about 29 ° C. Also, since matsutake mushrooms propagate in a ring shape, spores are sown in an arc shape. Since the leaf litter 6 has a function of blocking sunlight, spores are not killed.

[0014]

According to the first aspect of the present invention, matsutake is planted on a mixture of red pine wood chips and rice bran and left in a constant temperature environment of about 29 to 32 ° C., so that all the spores of matsutake fall. However, there is an effect that spores of Matsutake mushroom can be collected without omission. Further, the mixture contains an appropriate amount of water and nutrients, and thus has the effect of promoting the growth of matsutake mushrooms belonging to fungi and obtaining nutrients only from hyphae.

According to the second aspect of the invention, the spores inhabit while supplying the nutrients and water for keeping the mixture together with the spores in a temperature environment of 18 ° C. or lower from the mixture, and the spores can be sown at any time. effective.

According to the third aspect of the present invention, since an arc-shaped depression is formed in the soil, matsutake mushrooms have an effect of assisting in propagation in a ring shape.
