Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for artificially cultivating Matsutake mushrooms using an artificial medium suitable for the growth of Matsutake mushrooms.

[Conventional technology]

Matsutake is a fruiting body of a basidiomycete belonging to the family Matsutake, and grows naturally in autumn forests of red pine and hemlock, and is a mushroom that occupies the throne among mushrooms due to its aroma and delicious taste.

For this reason, various artificial propagation attempts have been made in the past, but no success has been achieved in artificial cultivation, such as with shiitake.

[Problem that the invention seeks to solve]

An object of the present invention is to provide a novel method for artificially cultivating matsutake using an artificial medium.

[Means for solving problems]

In the artificial cultivation method of matsutake of the present invention, a root blocking layer is provided around the exposed middle part of the tap root of a red pine seedling by placing stones or the like at a distance from the tap root. The roots that have grown out above the root blocking layer are spread out and covered with sandy soil to create an artificial medium in which the red pine seedlings are planted. Spores detected from Matsutake mushrooms or mycelium that have cultured spores are planted in an artificial medium, and a shallow layer of soil on top of the root-blocking layer is used to form a white that will generate Matsutake mushrooms.

The root blocking layer is provided so that many roots of the red pine seedlings, excluding some of the tap roots, spread shallowly into the soil covering layer and extend laterally. However, in order to prevent the tree from falling due to wind, snow, etc. after it has grown, a root blocking layer is not formed around the tap root and a hole is left so as not to prevent the tap root from extending into the ground. The materials used to form the Nehito layer are crushed stones such as granite, gravel, and other debris, Vi! Pieces of tiles or concrete pieces can also be used. The root layer is made of these large and small materials to form a layer of at least 5 cm to 20 cm around the red pine seedlings, excluding the tap root.
Form by laying in layers to a thickness of cm. Then, a large number of roots, excluding the tap root portion that penetrates the root blocking layer, are spread out on the root blocking layer and covered with sandy soil to create an artificial medium in which red pine seedlings are planted, for example, at equal intervals. This type of artificial culture medium does not require a flat area, and can be used on the slopes of mountains and hills, and is no different from a pine forest or pine mountain in appearance.

As the sandy soil, acidic sandy soil based on quartz sedimentary rock, granite, etc. and suitable for the growth of red pine is preferable. A thickness of 30 am is sufficient for the soil covering layer, and most of the roots of the red pine seedlings are shallowly spread through the soil covering layer, making it easy to create a ridge where matsutake mushrooms can grow.

〔Example〕

The topsoil of a 1-are weathered granite hill slope is scraped off, and red pine seedlings that have grown to 40 to 50 C11 are planted at 1 m intervals with their tap roots exposed, and holes with a diameter of approximately 10 cm are created around the tap roots. The Nehito layer was created using fist-sized crushed stones of weathered granite to a thickness of about 10cm11, and the other roots of the above seedlings were spread out on top of the Nehito layer, and the granite layer was placed 2 meters underground. The soil was covered with acidic sandy soil to a depth of 30 cm.

After about a year, it was confirmed that the red pine seedlings were growing finely with fine roots above the root layer, and the caps of three matsutake mushrooms with broken veils collected that fall were cut into 2-3 pieces. The mixture was poured into 21 water, mixed uniformly with 1001 sawdust, sprinkled on top of the soil covering 81 red pine seedlings, and thoroughly watered. On the second afternoon, we harvested 143 matsutake mushrooms, weighing 12 kg.

According to the present invention, there are the following effects.

〔Effect of the invention〕

■ The roots of red pine spread shallowly, creating a wide white area around the tree that allows matsutake to grow.

■ Artificial culture medium is easy to manage because seedlings are planted at a constant height.

■ Increased revenue can be expected as the seedlings grow.

Claims (1)

[Claims] 1. Create a root blocking layer by laying stones, etc. around the middle part of the tap root of the red pine seedling, apart from the tap root, and cover the roots that have grown out on the root blocking layer with sandy soil. 1. A method for artificially cultivating Matsutake mushrooms, the method comprising: creating an artificial medium in which Matsutake spores or mycelia obtained by culturing Matsutake mushrooms are inoculated.
