Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a house for cultivating shiitake mushroom logs.

(Background) The working process for cultivating shiitake mushroom logs is to inoculate the logs that have been felled from autumn to spring with shiitake mushroom inoculum from winter to spring.
Temporary laying down is carried out for about two months, and then formal laying down is carried out for about six months to a year and a half, and once the mycelium has spread sufficiently within the wood, we move on to the generation process. The generation process involves repeating the process of growing mushrooms by soaking them in water and resting them 5 to 10 times over a period of about one and a half to three years.

In this process, it is advantageous from a business standpoint to shorten the combined period of temporary cover and final cover, that is, the period of mycelial spread, and to generate mushrooms as soon as possible after inoculation. In order to promote the spread of mycelia, the method of initial temporary laying management is particularly important, and if the initial mycelial settlement and elongation proceed smoothly, the subsequent formal laying period can be significantly shortened. .

(Prior Art) Based on the above-mentioned idea, there are the following devices that have been used in the past to perform temporary laying down.

As a first example, Fig. 4 shows temporary laying down in an artificial hoarding field. In an artificial hodder field in which light-shielding materials 14 such as black shading nets or reeds are installed at a height of about 2 m, sleepers 16 are arranged in two rows on blocks 15 arranged on the ground, and hodaki trees 13 are placed on top of them. Stack horizontally to a height of about 1m. A passage is provided between the horizontally stacked rows, and a watering nozzle 17 is installed as a watering device under the light shielding material 14 to supply water to the logs once or twice a day.

As a second example, FIG. 5 shows temporary laying down using a house. A water nozzle 17 is installed on the upper part of the inner surface of the house, a ventilation fan 8 is installed on the gable side of the house, and an intake part 18 is provided on the opposite gable side. Hodagi 13 will be stacked with cross-sections from the ground to near the ceiling. When the ventilation fan 8 is operated, a wind is generated from the intake section 17 toward the gable side on the side where the ventilation fan 8 is located, and the outside air hits the area around the hodaki 13. The operation is carried out for one to several hours a day. Also, water is supplied to the tree trunks 13 by the watering nozzle 17.

(Problem to be solved by the invention) In the first example described in the conventional technology, wind passes through the passage, the upper part of the horizontally stacked wood, and between the blocks, so the area along the passage is The outside air hits the bark surface of the wood ends and the bark of the wood piled in the top and bottom rows. However, since it is difficult for wind to pass through the gaps between the hodaki in the middle row, air is always stagnant on the surface of the bark of the middle hodaki.

Next, if we consider water supply, we can adjust the amount of water to the topmost tiered hodaki, but for the second tier and lower tiered hodaki, there is a path for water to flow. There are hodaki that hang, and hodagi that don't hang, and even within a single hodagi, there are parts that hang and parts that don't hang.

As mentioned above, this method shows that the wind and water conditions are not uniform from one tree to another, and even within a single tree. For this reason, areas where water passes through and are not exposed to wind are always kept under damp conditions, and as the outside temperature rises, harmful bacteria are likely to grow. On the other hand, in places where there is good wind but insufficient water supply, the wood can dry out rapidly, causing poor elongation of shiitake mycelia, and in either case, the subsequent growth of mushrooms is likely to be poor. Become.

Furthermore, in the second example, when the ventilation fan is activated, wind is generated in the direction of the gable, but the wind strongly hits the logs in the parallel piles facing the intake section where the wind flows in, but moves away from the intake section. Accordingly, the wind becomes weaker, and its strength can vary depending on the position in the house. In addition, in the case of stacking a single pile of cross-legged wood, the hodaki are stacked one at a time, shifting each row in the right angle direction.
The direction of the wind is different.

The wells are stacked so that each row is shifted in the right angle direction, but the hodagi are stacked horizontally, so when watering is applied, there is a path for the water to pass through, as in the first example, and there is no variation in the amount of water applied. Get out. Furthermore, when the height of the stack becomes 2 to 3 meters, water flows out to the outside of the well girder, making it difficult for water to splash onto the wood at the bottom of the well girder, and the wood at the top and bottom of the well girder prevents moisture from flowing. The difference tends to become large.

Even with this method, the wind and water conditions on the wood are not uniform, resulting in the same problems as in the first example, partial outbreaks of harmful bacteria, and poor elongation of the shiitake mushroom hyphae, resulting in insufficient mushroom growth. becomes.

The present invention was developed in view of the above-mentioned problems of the conventional technology, and its purpose is to provide uniform environmental conditions to the tree trunks during the temporary laying period, especially to prevent wind and water. The present invention aims to provide a house for cultivating shiitake mushroom logs that can uniformly control the conditions.

(Means for solving the problem) In order to achieve the above object, the house for cultivating shiitake mushroom logs in the present invention is constructed by laying a net or drainboard at a height of 5 to 30 cm from the ground surface inside the house body, and An air intake is provided at the lower part of the side of the house, a ventilation fan is provided at the upper part of the gable or the roof, the other sides, gable and roof are of a sealed structure, and a water sprinkler is provided at the upper part of the house body.

In order to improve work efficiency inside the house, a passage is provided inside the house body, a net or slat is laid in the area other than the passage, and the boundary between the passage and the part where the net or slat is laid is placed at a height of 100 to 150 cm from the ground surface. Preferably, the shielding material, such as a plastic film, is stretched vertically.

(Function) When the ventilation fan is operated to exhaust air, outside air flows in only from the intake port at the bottom of the side of the house, and the outside air passes through the gaps between the screens or drainboards and becomes an upward airflow.
Head towards the ventilation fan at the top of the house. Also, a water sprinkler system will sprinkle water inside the greenhouse.

(Example) Examples will be described with reference to the drawings.

In Figures 1 and 2, inside the house main body 1, a passage 2 is provided in the center, and a net 3 is laid horizontally at a height of 15 cm from the ground in areas other than the passage 2. An iron frame 4 is installed at the boundary of the area where the fence is laid, and vinyl is stretched along the frame 4 from a height of 110 cm on the aisle side to the ground surface as a shielding material 5.
The roof of the house main body 1 is dome-shaped, vinyl 6 is used as the covering material, a ventilation fan 8 is provided on the upper part of the gable side 7 of the house main body 1, and both sides 9 have air inlets 10 extending over the entire length to a height of 10 cm from the ground surface. and intake port 1
0 is a damper type, and has a structure that automatically closes except when the ventilation fan 8 is in operation. The covering of the house main body 1 is the gable side 7 except for the ventilation fan 8 and the intake port 10 on the roof side.
Except for the provision of an entrance/exit 11, the structure is sealed, and when the entrance/exit 11 is closed, almost no air enters or exits. The watering device 12 is a simple one, which is a vinyl pipe with many small holes made, and is placed on top of the vertically stacked wood 13 as described below. This is an inexpensive watering device that can spray water at the normal water pressure used in households.

To explain how to use it for temporary laying down, the inoculated wood 13 is stacked vertically on the net 3 of the house body 1 and inside the frame 4. Figure 3a shows the ventilation fan in operation. When the entrance/exit 11 is closed and the ventilation fan 8 is operated to exhaust air, the air in the upper part of the house main body 1 is exhausted, while the outside air flowing in from the intake port 10 passes through the mesh 3 and is surrounded by the shielding material 5. An upward airflow passes through the vinyl and the area surrounded by the vinyl 6 of the house covering material. Here, with respect to the area of the part where the net 3 is laid, the distance between the vertically stacked hodagi 13 is
15 to 25%, and since the rising air passes through the spaces with a limited area, it passes through all the spaces and even the very small spaces (the pipes inside the Hodagi). The fresh outside air passing through the intake port 10 comes into contact with the bark surfaces of all the hodashi trees 13 and also rises through the pipes inside the hoda trees 13.

Further, Fig. 3b shows the state during watering. Since the sprinkled water flows along the surface of the vertically stacked hodagi 13, there is almost no moisture difference between the top and bottom of a single hodagi 13, and even if too much water is applied, the excess water is quickly drained away from the net 3. It has flowed away under Hodagi 1.
No. 3, the water content will not become too high. If the amount of water sprinkled is small and there are areas that are not covered, increase the number of water pipes and sprinkle more water to cover every corner. Even if there is some variation depending on the location, the excess water will flow away. , the water supply to Hodagi 13 becomes nearly uniform.

Furthermore, the hodagi 13 is located on the net 3 and is away from the soil where there are many harmful bacteria such as Trichoderma.
Infection with harmful bacteria from the soil is greatly reduced.

Next, a method of using the house of the present invention as a management house during rest of the generation process will be explained.

During the rest period, the wood is stacked vertically in the same way as temporary laying, but it can be used almost all year round, and when the outside temperature rises (May to November), it can be used. , put a light-blocking net on the outside of the house to prevent the house temperature from rising. Additionally, when the temperature rises during the day, a ventilation fan is activated to bring in outside air and lower the temperature inside the greenhouse. Additionally, when the temperature inside the greenhouse exceeds 25°C, the trees are sprinkled with water intermittently, and a ventilation fan is activated to blow wind onto the trees, which lowers the temperature of the trees through the heat of vaporization of the water. . When the outside temperature drops (December to April), a hot air heater is installed inside the house and a vinyl duct is passed under the net to heat the house.The warm air warms the wood from below. As it rises between the trees, it also warms the upper part of the trees, making it possible to warm the entire tree.

As mentioned above, nets support the trees, allow updrafts to pass through, and drain away excess water from watering.Slats can also be used in place of nets, as they work in the same way as nets. can.

(Effects of the invention) Since the present invention is configured as described above,
This produces the following effects.

As for the equipment, it is a simple equipment that uses only a ventilation fan, which can send air around and inside all the tree trunks, supplying fresh air almost uniformly to the bark surface and conduit area, and can be used for watering. As a result, the moisture conditions of the wood can be managed to be almost uniform, and since the wood is managed on a net away from the soil, which has a lot of harmful bacteria such as Trichoderma, the invasion of harmful bacteria is minimized. can do. Therefore, during the temporary laying period, the shiitake mushroom mycelia can grow smoothly and healthily into the wood, and mushrooms can occur approximately 6 months after inoculation, and the amount of mushrooms generated increases because there is less loss due to harmful bacteria. In addition, during the resting period, the shiitake mushroom hyphae can quickly rest and recover, which has the effect of promoting preparations for the next generation of mushrooms.
