JPS5850689B2 - Shiitake mushroom cultivation method - Google Patents

Description

[Detailed Description of the Invention] Conventionally, when cultivating shiitake mushrooms such as year-round cultivation, especially after inoculating the tank water and until the bacteria take root, the tank water is brought together and placed above and below the tank water. They laid down coniferous leaves, straw, etc., then covered the top with cocoon, insects, film, etc., and kept the tank water at a high temperature and humidity in an attempt to promote the survival of bacteria.

However, since tree leaves, straw, cocoons, snails, etc. are plant-based natural products, they are heavily colonized by bacteria such as Staphylococcus spp., and the binding effect of these bacteria significantly reduces the survival of Shiitake fungi.

again! This accelerated cultivation method is often used for cultivation in suburban areas, as they are often shipped as so-called "raw shiitake mushrooms," and for this reason, the shiitake mushrooms are grown in the suburbs of cities.

It is difficult to obtain straw, como, mulch, etc. in recent years, and it takes a lot of effort to spread them above and below the tank water, and it is difficult to spread them evenly, so it is difficult to uniformly heat and humidify the entire tank water. It was difficult to do.

The inventor of the present invention took into consideration the shortcomings of the above methods of cultivating shiitake mushrooms, and as a result of intensive studies, he arrived at the present invention, which is an ideal cultivation method.

That is, a breathable mat 2 made of synthetic resin foam or synthetic fiber with a porosity of 80 to 95 qI) is moistened with water, the mat covers the tank water 1 after the shiitake mushrooms have been planted, and then the mat is made impermeable. Cover with membrane 3.

This is a method of cultivating shiitake mushrooms that promotes the survival of shiitake fungi.

The basic conditions that encourage Shiitake mushrooms to take root are constantly heating the tank water,
Place it under humidification.

In other words, the water-impermeable membrane 3 has a heat-retaining effect that blocks outside air and prevents a drop in internal temperature due to air convection, and at the same time has the effect of preventing evaporation and release of moisture from the interior and constantly retaining a certain amount of moisture inside.

Suitable materials for the water-impermeable membrane include films made of synthetic resins such as polyethylene, polyvinyl chloride, polyester, polypropylene, polyamide, polyurethane, and polyvinyl alcohol, or foam sheets made of discontinuous cells.

Further, the mat 2 made of synthetic resin foam or synthetic fiber acts as a heat insulating layer for the tank water 1 and at the same time moistens the water, so it has a humidifying effect on the tank water.

In this humidifying effect, since the mat 2 covers the top and bottom of the tree, as the temperature rises during the day, the moisture contained in the lower mat 2 turns into steam, moistens the wood, and is adsorbed to the upper mat 2, and at night. On the other hand, during the daytime, the moisture adsorbed on the upper mat 2 moistens the tank water while descending and is adsorbed on the lower part 2.

In this way, while the mat 2 is repeatedly desorbed and desorbed day and night, the tank water 1 is kept in a heated and highly humidified state throughout the day, which is ideal for bacteria to take hold.

Furthermore, moisture is repeatedly desorbed from the mat, but in order for this moisture to be desorbed, the mat must be breathable (breathable) through which water vapor can pass, and the porosity must be between lead and 95%. The ball must be thrown within the range of the person in charge.

In other words, when the porosity is over 95%, the structure is too coarse and has poor ability to adsorb water, and can become a water-containing carrier.On the other hand, when the porosity is less than 80%, it is too dense, making it difficult to desorb water, and the water-containing volume within the structure is small, making it impractical. Not.

Furthermore, since the mat is made of synthetic resin foam or fiber, unlike natural materials such as tree leaves and straw, it is difficult for bacteria such as staphylococci that have an anti-coagulant effect with Shiitake fungi to grow, and Shiitake fungi can grow freely. The rooting of the plants is promoted.

In addition, suitable materials for the mat include open-celled synthetic resins such as polyurethane, polyethylene, and polyvinyl alcohol, or woven, knitted, and nonwoven fabrics made of synthetic fibers such as polyester, polyamide, polypropylene, polyvinyl chloride, polyacrylic, and polyvinyl alcohol. be.

However, even if the mat contains a small amount of 20 to 30% of natural fibers such as cotton, rayon, etc., if the mat is mainly made of synthetic fibers, the growth of bacteria that can interact with Shiitake fungi will be relatively small. It can be used as the mat.

In addition, since it is mat-like, it is easier to handle than conventional leaves, straw, etc., and labor-saving cultivation is possible.

As described above, the present invention provides an extremely practical method for cultivating shiitake mushrooms that provides ideal conditions for the cultivation of shiitake fungi.
