Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a culture medium end section, and more particularly to a culture medium bulb box suitable for growing pine mushrooms.

[Conventional technology] Pine mushrooms, especially pine mushrooms called champignons, which are a specialty of France, are cultivated in their native land using unique techniques cultivated over a long history. This kind of technology is not available to outsiders.

It is usually not taught to outsiders, especially foreigners.

Also, even if you receive instruction in training techniques.

Growing pine mushrooms in foreign countries is difficult.

This is because the climate and natural features of the native land and foreign countries are different, and it is difficult to obtain the same culture medium as the native land.

Therefore, people who are interested in the production of pine mushrooms are working on research on various methods of producing pine mushrooms.

In the cultivation of pine mushrooms, a ball box is usually used to store (bed) the medium in which post-fermentation has been completed, and pine mushrooms are cultivated by planting seedlings in the medium placed in the ball box.

Using a ball box allows the medium to be controlled in quantitative quantities and the culture medium can be handled together with the ball box, making it extremely convenient to handle when sterilizing or cultivating pine mushroom fungi in separate rooms. It is from.

In order to efficiently produce high-quality pine mushrooms, it goes without saying that the culture medium itself must have a component composition suitable for pine mushrooms, but the ball box for the culture medium also has a major impact on pine mushroom growth and workability. It is something.

[Problems to be Solved by the Invention] However, although the above conventional floor surface is open at the top, it is not possible to sufficiently remove harmful substances such as carbon dioxide (CO□) generated from the culture medium. In addition, it was not possible to take in the oxygen (02) necessary for the growth of bacteria or to sufficiently adjust the humidity.

[Means for Solving the Problems] In order to solve the problems of the conventional art, the present invention provides a plurality of through holes in the side plates and the bottom plate of the box whose upper end is open, and also provides a plurality of through holes in the outer circumference of the lower surface of the bottom plate. A plurality of legs are provided protruding from the top to form a culture medium floor surface.

[Function] In the culture medium floor with the above structure, each of the side and bottom plates of the floor is provided with a plurality of through holes, so it has good ventilation, and is useful for removing CO2 etc. generated from the culture medium and growing pine mushroom fungi. The necessary supply of 02, humidity adjustment, etc. can be sufficiently performed.

In addition, since a plurality of legs are protruded from the outer periphery of the lower surface of the bottom plate, a space can be formed between the bottom plate and the floor surface, so that when handling the culture medium and the floor surface using a forklift etc. The fork can be easily inserted into the above-mentioned space. Furthermore, when stacking a plurality of floors containing culture media, the above-mentioned legs serve as positioning supports, improving work efficiency.

[Example] Hereinafter, an example of the culture medium floor surface according to the present invention will be described in detail.

FIG. 1 is a perspective view showing the culture medium floor surface of this embodiment. This culture medium bed box 1 is made of synthetic resin and is a flat rectangular parallelepiped box with an open top. And this culture medium floor surface 1
A large number of small through holes 4 are perforated in the front surfaces of the side plates 2 and bottom plate 3, respectively. Further, legs 5 are provided at the four corners of the lower surface of the bottom plate 3, respectively, at positions offset inward from the corners by the thickness of the side plate 2.

As shown in Fig. 2, the culture medium 6 which has undergone post-fermentation is placed in the culture medium Kawadoko box 1 having such a configuration, and is used for planting seedlings, collecting generated pine mushrooms, or disposing of the culture medium. Handling becomes extremely easy.

In particular, this culture medium floor surface 1 has a large number of through holes 4 in its side plates 2 and bottom plate 3, so it has good ventilation, which helps in removing CO□ gas generated from the culture medium 6 and preventing pine mushroom fungi. It is possible to sufficiently take in 02 and adjust humidity necessary for growth.

Furthermore, this culture medium floor surface 1 has legs 5 of a predetermined length protruding from the four corners of the lower surface of the bottom plate 3, so that a space can be formed between the culture medium floor surface 1 and the floor surface. When handling the medium 6 with a forklift with the medium 6 loaded in the bed, the fork can be inserted from any position.

On the other hand, as shown in FIG. 3, when the culture medium floor 1 is stacked in the height direction, the legs 5 provided on the bottom plate 3 are offset inward from the corners by the thickness of the side plate 2, so the legs 5 serves as a guide member during positioning, making it easy to stack the culture medium bed boxes 1, and when stacking them, no displacement occurs.

Moreover, if the size of the culture medium floor surface 1 is set to a size that allows the operator to collect the grown pine mushrooms by simply extending his hand, the workability will be extremely good.

Although synthetic resin was used as the material for the culture medium bed surface 1, the present invention is not limited to this example, and for example, wood or a rust-resistant light alloy may be used.

Incidentally, the culture medium to be placed on the culture medium floor according to the present invention is manufactured as follows.

First, the pre-fermentation process of the medium will be explained.

First, cut the rice straw into three pieces, each about 20 am long. Next, cut the rice straw to a height of, for example, 1 m and a width of 1 m.
Pile it up. In stacking in this case, the depth may be arbitrary. Note that wheat culms may be used instead of rice straw. After that, water is thoroughly sprinkled on the rice straw piled up. This watering amount is 150 parts by weight of rice straw per 100 parts by weight.
Approximately 230 jusha departments. After that, the rice straw is left to ferment for one day. The fermentation state of rice straw at this time depends on the temperature and
Since it changes depending on humidity and the like, the above-mentioned deposition time may be adjusted as appropriate.

Then, the next day, chicken manure, rice bran, and oil cake are added to the rice straw. In this case, the input amount is 5 to 15 parts by weight of chicken manure, 3 to 10 parts by weight of rice bran, and 3 to 10 parts by weight of oil cake per 100 parts by weight of rice straw. Make sure to mix thoroughly. Also, at this time, if the outside air is dry and the moisture content of the rice straw is thought to be low, add an appropriate amount of water.

If the mixture is left as it is for 1 to 5 days, the temperature of the medium will rise due to fermentation. However, this fermentation is partially uneven. Therefore, we cut the mixture to break up the lumps and mix them well, replenishing air and making the composition uniform.
Accelerates overall fermentation and causes uniform fermentation. In addition, due to this turning, the temperature of the culture medium is partially reduced to 70°C.
This prevents the capacity of the medium from decreasing beyond this point.

Then, after 1 to 5 days have passed after this turning, the mixture is turned again and left for another 1 to 5 days to further promote uniform fermentation.

After sufficient fermentation in this way, 100 rice straws
Prepare 0.2 to 1 part by weight of urea per part by weight, and add this in several portions at striped intervals for 1 to 5 days. At this time, switch back as appropriate. Specifically, first, one-third of the prepared urea is mixed with rice straw and left for 1 to 5 days. After that, one-third of urea is mixed into the rice straw again and the temperature is adjusted by turning the mixture 2 to 10 times. After that, it is left to stand for 1 to 5 days, and the remaining one-third of urea is mixed in at the end. Then, leave it as it is for 1 to 5 days. The reason why urea is mixed in multiple batches is to prevent rapid fermentation and to ensure uniform fermentation.

After that, after cutting back, adjust the moisture content of the culture medium.In other words, if you hold the culture medium in your hand and water seeps out,
Mix the plaster and adjust the moisture so that water does not seep out even when squeezed with one hand. When adding gypsum, the input amount is 1 rice straw
The amount is 0.5 to 2 parts by weight of gypsum per 00 parts by weight. The pH of the medium after adjusting the water content is preferably about 7, and if the pH is not about 7, it is adjusted with acid or alkali as appropriate.

In the above manner, prefermentation of the medium is completed.

The period required to complete this pre-fermentation is about 17 days in summer, about 23 days in spring and autumn, and about 28 days in winter.

The medium thus obtained is then subjected to a post-fermentation step. This post-fermentation process sterilizes bacteria floating in the air, removes ammonia contained in the medium after pre-fermentation, and creates a biological environment suitable for the growth of pine mushroom mycelia.

In this process, first, the medium after pre-fermentation is heated to 40-50%
The mixture is loosened and placed in a container at a height of aa, and the container is placed in a post-fermentation chamber where temperature and humidity can be controlled.

After this, the first fermentation was carried out at a culture medium temperature of 60°C and room humidity of 100% for 8 hours, and the second time was carried out at a temperature of 55°C.
Leave it for 2 days at 100% humidity.

Then, for the third time, it was left for 3 days at a temperature of 50°C and a humidity of 100%. Then, for the fourth time, the temperature was 45℃ and the humidity was 100%.
Leave it for 2.5 days, and then raise the temperature to 23.5 days for the fifth time.
Lower the temperature over 3 days to 5°C and 100% humidity.

As described above, the post-fermentation process is completed. In the above-mentioned post-fermentation process, temperature and humidity must be controlled extremely accurately, and temperature and humidity must be checked every hour for accurate control.

The medium that has undergone post-fermentation in this way is transported to the cultivation room, where it is placed in the cultivation room.

During this loading operation, since the medium after completion of post-fermentation is hard, it is broken up into pieces and placed in the medium bed box according to the present invention. In this case, the amount of entering the bed is 250 kg to 300 kg per tsubo, and the time of entering the bed is 24 hours. Furthermore, after entering the bed, ventilation is performed for 10 minutes every two hours, for example, to remove CO□ gas generated from the culture medium. This is because when the CO2 concentration is high, the axis of the pine mushroom becomes longer and the pine mushroom cap opens more easily.
This is because the growth of pine mushrooms will be inhibited.

Also, throughout the bed period, the temperature inside the cultivation room is kept at 18°C, while the temperature of the medium is kept at 23.5°C. The growth of pine mushroom mycelia is optimal under these temperature conditions.

If pine mushrooms are grown using the medium thus obtained, the following effects will be obtained.

In other words, when placing the culture medium into the bed, the culture medium is placed in a flat shape in a culture medium bed box with many through holes, which provides good ventilation and therefore reduces the supply of zero during ventilation. while CO2 is effectively removed from the culture medium. In addition, the temperature of the culture medium and the temperature of the cultivation room are kept at a temperature suitable for growing pine mushroom mycelium before entering the bed.
This will prevent a decrease in culture medium capacity. As a result, if pine mushrooms are produced using the medium thus obtained, a large amount of good-quality pine mushrooms can be produced.

In addition, the bed entry time, ventilation interval, ventilation time, room temperature and culture medium temperature when entering the bed may be changed as appropriate.In short, enter the bed in a flat state, thereby improving the ventilation of the culture medium. The temperature in the culture medium and cultivation room may be adjusted to a temperature suitable for the growth of pine mushroom mycelia during the cultivation period. By the way, the appropriate ventilation intervals were 1 to 3 hours, the ventilation time was 5 to 15 minutes, the culture medium temperature was 20 to 25°C, and the room temperature of the cultivation room was about 15 to 20°C. One of these days,
In particular, the above conditions were excellent for growing pine mushroom mycelia.

[Effects of the Invention] As described above, according to the culture medium Kawadoko box of the present invention, a plurality of through holes are provided in each of the side plates and the bottom plate of the box whose top end is open, and a plurality of legs are provided on the outer periphery of the lower surface of the bottom plate. The protruding structure provides good ventilation and reduces CO3 generated from the culture medium.
It is possible to sufficiently remove pine mushrooms, supply O2 necessary for growing pine mushroom fungi, adjust humidity, etc., and improve work efficiency, so high-quality pine mushrooms can be efficiently produced in large quantities.
