Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method for cultivating mushrooms such as champignons.

[0002]

2. Description of the Related Art Conventionally, in general, mushrooms are generally cultivated by first adding nutritive additives to sawdust and the like, adjusting the water content appropriately, and then thoroughly stirring and packing in plastic bags or bottles and sterilizing by autoclaving. Go and create a cultivation floor. This culture bed was inoculated with inoculum, cultivated at an appropriate temperature and humidity to generate fruiting bodies and grow to an appropriate size, and then harvested.

[0003]

In the case of the above-mentioned conventional technique, since the fungus is directly planted on the cultivation bed, it is necessary to sterilize the entire cultivation bed, which is troublesome and time consuming. In addition, after harvesting several times, the cultivation bed from which fruit bodies did not occur was abandoned, which required a large amount of waste and required time and labor.

The present invention has been made in view of the above-mentioned problems of the prior art, and is a champignon (mushroom) in which the manufacturing process is simplified and the labor required for the work is reduced.
Is the cultivation method.

[0005]

According to the present invention, the compost thus prepared is put in a resin bag and sterilized, and the sterilized instrument is used to inoculate a mushroom such as champignon. Then, a culture concentrated bacterial bed was obtained by culturing at a room temperature of 23 to 25 ° C. and a humidity of 80 to 85% for a certain period of time in a culture room equipped with management facilities, and spreading the mycelium in the compost,
This culture concentrated bacterial bed is loosened evenly in a diluted culture cultivated place where natural fiber is packed in a cultivating box, and is uniformly placed in a cultivating room equipped with management equipment at room temperature of 22 to 25 ° C and humidity of 90 to 95%.
It is a method of cultivating mushrooms, which is cultivated in and to generate and grow fruiting bodies of champignon, which is a mushroom.

[0006] Since the concentrated culture bed is cultivated for a certain period of time and the mycelia are infested, it is necessary to put it in a diluted culture cultivated area.
Mycelium spreads on the surface of the diluted culture cultivated area within 6 to 6 days, and fruit bodies develop within a few days. After the fruit bodies have been harvested several times, in the diluted culture cultivated area where the fruit bodies have stopped occurring, when the old culture concentrated fungal bed layer is replaced with a new one and the cultivation is carried out, the fruit bodies are generated again without changing the basic cultivation bed. It can then be grown and harvested.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a mushroom cultivation method according to this embodiment. First, Table 1 shows the materials of the compost 12 of the culture concentrated bacterial bed 10 shown in FIG. 1 and the mixing ratio thereof.

[0008]

[Table 1]

Water is added to the above mixture so as to be 65% to 70% of the total amount, sufficiently stirred, and then loaded into a compost forming frame. Then, switching back is performed every 5 or 6 days. After a certain period of time, lime is appropriately added to adjust the pH from 6.8 to 7.0, and the compost 12 is completed.

The above compost 12 is put in a heat-resistant and air-permeable antibacterial PP bag 14 which is a resin bag and to which an air-permeable antibacterial filter 13 is attached so that there is no space of about 3 to 4 kg per bag. Stuff in. And autoclave (110 ℃, 0.6
Kgt / cm ² ), sterilize for 30 minutes after the desired pressure temperature is achieved. After naturally cooling, in a clean bench, in the center of the upper surface of the compost, a drill hole 16 for inoculation of inoculum was introduced, and 2-3 ml of horse manure sencha juice agar solution was injected thereinto, and 50 ml of inoculum 18 of champignon was injected therein. The inoculum inoculation drill hole 16 is closed with a hole filling agent 19 made of the same medium, compost 12. The equipment used for inoculation of seeds should be flame sterilized. Then, the opening of the heat resistant and air permeable antibacterial PP bag 14 is closed with a rubber band or the like.

Heat-resistant and air-permeable antibacterial PP bag 14 that has been inoculated
Place in a culture room with well-equipped management equipment, room temperature 23-25
The temperature and humidity are set to 80 to 85%, and the ventilation is performed by changing the total volume twice a day. After a certain period of time, compost 12
The inside of each of the cells was infested with hyphae, and the culture was completed.

Next, a diluted culture cultivated area 20 is prepared in which the culture concentrated bacterial bed 10 is planted. The basic cultivation bed 22 made of natural fiber used for the diluted culture cultivation area 20 is formed by mixing the materials shown in the following table according to the mixing ratio.

[0013]

[Table 2]

Water was added to the above mixture so as to be 65% of the total amount, and after sufficiently stirring, put in a loading frame, and
It is cured for a day and cut back once on the way to complete the basic cultivation floor 22.

Wooden cultivation box 24 (60 cm square, depth 30 c
m) from the bottom of the cultivation box 24 to the above-mentioned basic cultivation floor 22 by 15c
Insert evenly to m and press lightly. The opening above the cultivation box 24 is covered with a newspaper containing water and left in that condition for 3 to 4 days. After that, the concentrated culture bed 10 is crushed on the basic cultivation bed 22 and uniformly spread over one surface to form a concentrated culture bed layer 26. At that time, two heat-resistant and air-permeable antibacterial PP bags 14 are used for each cultivation box, and the culture concentrated bacterial bed layer 26 has a thickness of 40 to 60 mm. And cultivation box 2
Recover the upper opening of 4 with a moistened newspaper,
In that state, leave it in the cultivation room for 5 to 6 days. During that time, the mycelium of champignon spreads on the surface of the basic cultivation floor 22.

Next, peat moss and Kanuma soil were mixed at an appropriate ratio, and water was added so as to be 65 to 70% of the total amount, and the mixture was sufficiently stirred to cultivate with a cover soil 28 to concentrate and concentrate the bacterial bed. Cover the surface of layer 26. At that time, the thickness of the soil cover 28 is 30 to 4
Set to 0 mm. In that state, room temperature 22-25 in the cultivation room
C., humidity 90 to 95%, ventilation is circulated with the same air to continue culturing, and after a certain period of time, champignon fruiting bodies 30 are generated on the surface of the soil 28. Then room temperature 14-17
After changing the setting to ℃, humidity 75-80%, after a certain period of time,
It grows to a size suitable for harvesting and harvests this appropriately.

Occurrence of champignons occurs 5 to 6 times in one period, that is, about 60 to 70 days after the occurrence.
In the diluted culture cultivated land 20, when the generation of fruiting bodies is not less after one period ends, the old soil cover 28 and the culture concentrated bacterial bed layer 26 are removed, and the new cultured concentrated bacterial bed 22 is placed on the basic cultivation bed 22. When the soil and cover soil 26 are sequentially spread and cultivated by the above method, the champignon can be cultivated again. In this way, the basic cultivation floor 22 can be continuously used for one year.

According to this cultivating method, the process of inoculating the inoculum to culturing the hyphae is performed in the culture concentrated bacterial bed 10, so that sterilization and culture management can be centrally performed and efficiency is high. Moreover, since it is not necessary to sterilize the entire diluted cultivation area 20, the work is reduced and it is convenient. And basic cultivation floor 2
The item 2 reduces the amount of waste and the cost of rebuilding because it can be used repeatedly.

It should be noted that the present invention is not limited to the above-described embodiment, but can be modified as appropriate. What is suitable other than the above, such as the kind and mixing ratio of the materials and the size of the container, is appropriately selected and used.

[0020]

According to the mushroom cultivation method of the present invention,
The effort required for the work can be reduced and the management can be facilitated.
