Abstract

PURPOSE: To obtain mushrooms having high qualities in a shortened culture period in excellent productivity by harvesting the mushrooms, while leaving the root part in a culture bottle, removing a part of the root part to expose the mushroom culture medium, adding water, and subsequently performing the second culture of the mushrooms. CONSTITUTION: When mushrooms such as Hygrophorus hypothejus and Tricholoma protentosum are harvested, the root part D is left in a culture bottle B. After the harvest, a part of the root part D is removed to expose the mushroom culture medium. Water is added into the culture bottle B to perform the second culture of the mushrooms. After a part of the root part is removed, the left root part is preferably formed in a shape similar to a doughnut.

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 mushrooms suitable for cultivating mushrooms such as humor mushrooms.

[0002]

BACKGROUND AND PROBLEMS Generally, bottle cultivation methods for artificially cultivating mushrooms such as enoki mushrooms, shiitake mushrooms and shiifurifuri mushrooms are widely known. In the bottle cultivation method, a mushroom medium filled in a cultivation bottle is inoculated with a mushroom inoculum to carry out mycelial culture and growth and cultivation of fruit bodies.

By the way, in such bottle cultivation method, if water is added to the mushroom medium after harvesting the mushrooms and the mixture is allowed to stand, the mushrooms bud again and the mushrooms can be harvested in about 20 days. Such cultivation method is called so-called second cropping cultivation, but the mushrooms that are harvested have poor quality and little yield, so they have little commercial value and are not commercially practiced. .

The present invention has responded to such a background, and in particular, it dramatically enhances the quality of mushrooms in the second cropping and enables the commercial production by shortening the cultivation period and securing the yield. The purpose is to provide a method for cultivating mushrooms.

[0005]

The present invention provides a method for cultivating mushrooms by a bottle cultivation method, wherein at the time of harvesting mushrooms M ...
Mushrooms M are harvested while leaving the stone protrusions D in the cultivation bottle B, and a part of the stone protrusions D after the harvest is removed to expose the mushroom medium A. It is characterized by performing second crop cultivation of mushrooms M ... by adding them. In this case, it is desirable to form the residual stone protrusion Du after removing a part of the stone protrusion D in a donut shape. Further, it is suitable for mushrooms M.

[0006]

According to the mushroom cultivation method of the present invention, first, when the mushrooms M ... are harvested, the stone protrusions D are left and harvested. In this case, relatively small mushrooms such as enokitake mushrooms and honshimeji mushrooms usually harvest the entire mushrooms grown in one cultivation bottle, so that it is difficult to harvest by separating the stone protrusions from the mushrooms at the time of harvesting. is there. However, in the case of relatively large mushrooms such as shiifururi mushrooms, which are similar to matsutake mushrooms, one mushroom is usually harvested one by one. It is possible to leave the stone protrusion D in the cultivation bottle B after the end of harvesting.

On the other hand, the mushroom medium A is exposed by removing a part of the stone protrusion D by making a vertical cut in the stone protrusion D, for example. In this case, the residual stone projection Du can be formed in a donut shape by removing a part of the stone projection D on the center side.

[0008] As a result, since the residual stone projections Du and the mushroom medium A are present in the cultivation bottle B, if water is added to the cultivation bottle B and left to stand, mushrooms will germinate and the second pick of mushroom M will be taken. It can be cultivated. In this case, due to the presence of the residual stone protrusion Du in the cultivation bottle B, the mushroom grows by budding from the boundary between the residual stone protrusion Du and the mushroom medium A, and the cultivation period when there is no residual stone protrusion Du. Half of the cultivation period (7-
It can be harvested within 10 days. Moreover, the shortening of the cultivation period suppresses the propagation of various bacteria, and the quality of mushrooms is also improved to the level where commercial production is possible.

[0009]

Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

[0010] Examples will be described how to cultivate the mushrooms. First, when cultivating, the cultivation bottle (850c
c) is prepared, and the mushroom medium A, for example, a mushroom medium A prepared by mixing a main material such as sawdust with a nutrient such as rice bran to prepare water is packed. Then, an inoculation hole H is opened from the upper surface of the mushroom medium A and inoculated with the inoculum of shiifurifuri mushroom. After this, the mycelium is cultured, and if the mycelium spreads, the bacteria are scratched. As a result, mushrooms are sprout and the mushrooms grow after the growing period.

FIG. 2 shows the mushroom M grown in this way.
Is shown. Then, if the mushrooms M have grown before they can be harvested, the most harvest is taken. In this case, at the time of harvesting, the mushroom protrusions D are left in the cultivation bottle B and the mushrooms M ... Are harvested one by one.

As a result, after the mushrooms M ... are harvested,
As shown in FIG. 3, since a stone protrusion D having a thickness of about 5 to 10 mm remains in the cultivation bottle B, as shown in FIG. Cut through D and remove a part of it. Specifically, a donut-shaped residual stone projection Du as shown in FIG. 1 is formed in the cultivation bin B by removing a part of the stone projection D on the center side. When the 850 cc cultivation bottle B is used, the residual stone projection Du has an outer diameter Xo of 58 as shown in FIG.
mm, inner diameter Xi is around 38 mm (ring width W: 10 mm
Before and after) is desirable.

As a result, since the residual stone projections Du and the mushroom medium A remain in the cultivation bottle B, 5
Water of about 0 cc is added and left for 3 to 5 hours, and thereafter, the cultivation bottle B is inverted to drain water and left in the growth chamber for second cropping. in this case,
Since the residual stone protrusions Du remain, the mushroom M ... germinates and grows from the boundary between the residual stone protrusions Du and the mushroom medium A, as shown in FIG. You can harvest M ...

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment.
For example, cultivation of shirifurari mushrooms has been exemplified as mushrooms, but cultivation of other mushrooms is not excluded. In addition, the case where the residual stone projection D is formed in a donut shape is shown as an example.
Alternatively, the D-shaped residual stone projections Du may be formed by cutting along one of the straight imaginary lines S as shown in and removing one side. In addition, other detailed methods and the like can be arbitrarily changed without departing from the scope of the present invention.

[0015]

As described above, the method for cultivating mushrooms according to the present invention allows the mushrooms to be harvested by leaving the stone protrusions in the cultivation bottle at the time of harvesting the mushrooms, and removing a part of the stone protrusions after the harvest is completed. To expose the mushroom medium, and after this,
By adding water to the cultivation bottle, the second crop of mushrooms is cultivated, so that the quality of the mushrooms at the second crop of cultivation is dramatically improved, and commercial production is achieved by shortening the cultivation period and securing the yield. There is a remarkable effect that can be performed.
