Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cultivating shimomofuri mushrooms using a bottle cultivation method.

[0002]

[Prior Art and Problem] Conventionally, the cultivation method of shimofuri mushroom is as follows.
Similar to the method for cultivating bottles such as enoki mushrooms and shiitake mushrooms, the mushroom medium filled in the culture bottles was inoculated with the inoculum of the mushrooms to grow mycelia and fruit bodies.

However, as shown in FIG. 3, the shimofuritake mushroom Mo cultivated by such a conventional method has a diameter Da of the umbrella A.
Is more than three times the diameter Db of the stem B,
It was not always preferable from the viewpoints of commercial properties such as appearance and packaging.

In view of the above-mentioned conventional techniques, the present invention has an object of providing a method for cultivating shiitake mushrooms, which is capable of dramatically improving the commercial properties such as appearance and packaging.

Means and Embodiments for Solving the Problems The present invention uses a bottle cultivation method in a method for cultivating shimomofuri mushrooms. From the emergence to the harvest, the temperature condition is set to 14 to 18 ° C. The fruiting body is grown for several days without being irradiated with light, and thereafter, the fruiting body is grown while intermittently irradiating with light, and the fruiting body (shimofuritake mushroom) M ...
Harvesting is performed before the diameter Da of the umbrella A is three times as large as the diameter Db of the stem B. At this time, when the bacteria are scraped, the mushroom medium 3 is exposed like a donut on the periphery.

Further, according to the optimum embodiment, the intermittent irradiation of light is performed by changing the irradiation time to 1/9 of the irradiation stop time.
It is desirable to set it to about 1/18.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an optimum embodiment according to the present invention will be described in detail with reference to the process chart shown in FIG. 1 and FIGS.

First, in the cultivation, as shown in FIG. 4, a cultivation bottle 2 (850 cc) is prepared, and a mushroom medium 3, for example, a main material such as sawdust is mixed with a nutrient material such as rice bran. Stuff the mushroom medium 3 whose water content has been adjusted. And
The inoculation hole 4 is opened from the upper surface of the mushroom medium 3 and inoculated with the inoculum of the mushroom.

As a result, mycelia are cultivated (FIG. 1: step P1). When the mycelia culture progresses and the mycelia 5 spread on the upper surface of the mushroom medium 3, the mycelia are scratched (FIG. 1: step P2). As for the fungal scraping, as shown in FIG. 4, while scraping the mycelium 5 spread on the upper surface of the mushroom medium 3 almost horizontally,
The upper surface of the mushroom medium 3 is exposed in a donut shape at the periphery.
At this time, the width Dc of the upper surface of the mushroom medium 3 to be exposed is 5 to
Set to about 7 mm. The virtual line 5s indicates the upper surface of the hyphae before the fungus is scratched.

Thereafter, the fruiting bodies are sprouting (FIG. 1: step P3). The conditions for the sprouting step are a temperature of 15 to 1
The temperature is set to 8 ° C and the humidity is set to 95 to 98%, and no light is emitted. Then, by ventilating, carbon dioxide 1
Keep below 000ppm. This sprouting process is 7-1
It will be about 0 days.

Upon completion of the budding process, the process proceeds to the growing process (FIG. 1: process P4). The condition of the growth process is that the temperature is 14
-18 ° C, humidity is set to 90-93%, and carbon dioxide is suppressed to 1500 ppm or less by ventilation. Then, for several days in the early stage of the growth process (3 to 5
Days) without light. In the growing step, the temperature condition is particularly important, and the temperature is set to about several degrees Celsius lower than that in the sprouting step.

After that, fruit bodies are grown while intermittently irradiating with light. For intermittent irradiation of light, the irradiation time is set to 1/9 to 1/18 with respect to the irradiation stop time, desirably, the irradiation time is set to about 15 minutes, the irradiation stop time is set to about 3 hours, and The length is about 500 lux. Then, after about 15 days, as shown in FIG. 5, the fruiting bodies (shifurifuri mushrooms) M ... Grow until they can be harvested. In this case, the fungi scraping method M ...
Grows straight in size.

On the other hand, as shown in FIG. 2, the harvesting is performed before the diameter Da of the umbrella A of the Mushroom mushroom M becomes three times as large as the diameter Db of the stem B (FIG. 1: step P5). As a result, it is possible to harvest the vertically long sushi furitake mushroom M whose appearance is similar to a matsutake mushroom or the like in which the diameter Da of the umbrella A is relatively small. Also, because it is vertically long like this, it is not bulky when wrapped. As for the harvesting method, the stone protrusions are left in the cultivation bottle 2 and the shiifurifuri mushrooms M ... are harvested one by one.

Although the embodiment has been described in detail,
The present invention is not limited to such an embodiment,
The details can be arbitrarily changed without departing from the gist of the present invention.

[0015]

As described above, the method for cultivating shiifurifuri mushrooms according to the present invention basically sets the temperature condition to 14 to 18 ° C. from sprouting to harvesting and keeps light for several days after sprouting. The fruiting bodies are grown without irradiation, and after that, the fruiting bodies are grown while intermittently irradiating light, and harvesting is carried out before the diameter of the fruiting body umbrella becomes three times the diameter of the stem. As a result, there is a remarkable effect that the product properties such as appearance and packaging can be dramatically improved.
