Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a method for cultivating shiitake mushrooms for use in dried shiitake mushrooms and an apparatus therefor. The present invention relates to a cultivation method for obtaining high-quality shiitake mushrooms having a floral pattern on the surface during a low temperature period, and a cultivation device used for this cultivation. [Prior Art] In the cultivation of shiitake mushrooms, the cultivation techniques are fundamentally different between fresh shiitake mushrooms, in which the harvested shiitake mushrooms are shipped without any processing, and dried shiitake mushrooms, in which the harvested shiitake mushrooms are dried and shipped. For example, in the case of fresh shiitake mushrooms, it is necessary to concentrate family and hired labor throughout the year in order to perform artificial generation operations. On the other hand, dried shiitake mushrooms are produced as a side job using labor during the agricultural off-season, and are produced using shiitake mushrooms harvested without any artificial generation operations, so the natural forest that is the center of production is used to produce dried shiitake mushrooms. The conditions of the natural world, such as sunlight, ventilation, rainfall, temperature, and humidity, which are formed under the shiitake field, greatly influence the type and production amount of shiitake mushrooms. Therefore, the income of cultivators is greatly affected by whether or not they can harvest a large number of shiitake mushrooms, which are used as raw materials for dried shiitake mushrooms, and have a high cash value in the market. be. Here, donko refers to the high-quality ones that grow in the low temperature period from winter to early spring, when the outside temperature is low, and have thick caps. The donko that germinated later, and especially the donko with cracks on the surface of the cap, are called flower donko and have extremely high commercial value. Under these conditions, there is a lot of rainfall during the middle and high temperature seasons (spring, summer, and autumn) when the temperature rises and the growth of shiitake mushrooms is accelerated, but when there is little rain in the hoda farm, there are many small shiitake mushrooms and the yield is low. If there is little rain, and there is a lot of rain, shiitake mushrooms called amago, which have thin flesh and high water content, tend to grow and have little commercial value. However, in the low-temperature season (winter), when there is little rain and thick, high-quality shiitake mushrooms can be harvested, the harvest amount is currently very small because the outside temperature is low and the growth of shiitake mushrooms is slow. In contrast to the cultivation of dried shiitake mushrooms, fresh shiitake mushrooms are cultivated throughout the year, and as this is a specialized practice, they have traditionally been cultivated in greenhouses such as vinyl greenhouses. Japanese Unexamined Patent Publication No. 1983-249323 and Utility Model Publication No. 1983-
153159, Japanese Utility Model Publication No. 58-23228, and Japanese Patent Application Laid-open No. 52-50858 are known. [Problems to be solved by the invention] The cultivation of shiitake mushrooms using the above-mentioned greenhouses are all greenhouses for cultivating fresh shiitake mushrooms, and various considerations have been made to enable cultivation throughout the year. In particular, unlike dried shiitake mushrooms, if pedicels (cracks) form in the caps of shiitake mushrooms, the product value declines, so emphasis is placed on maintaining humidity and ensuring sunlight and ventilation within the greenhouse to prevent cracks from forming. For,
There are problems in that the structure of the house is extremely complicated and its operation is complicated. In view of the current situation, this invention solves the instability of the quality and yield of shiitake mushrooms grown in a natural environment in the cultivation of shiitake mushrooms for dried shiitake mushrooms, and provides consistently high quality shiitake mushrooms for dried shiitake mushrooms with excellent yields. With the aim of harvesting fresh shiitake mushrooms, we have conducted numerous research tests by improving the greenhouse cultivation method and greenhouse structure used to cultivate fresh shiitake mushrooms, and have developed a cultivation method for dried shiitake mushrooms according to this invention, and a method for cultivating dried shiitake mushrooms. We have now completed the cultivation equipment used in this method. [Means for Solving the Problems] The first aspect of the present invention is to inoculate a seed fungus that occurs during low-temperature periods and grow a tree in an outdoor tree field using a conventional method, at an outside temperature of 5 degrees Celsius or lower. When the mushrooms mature, they are moved into a greenhouse, and then the generation and growth of shiitake mushrooms is achieved by controlling the temperature, humidity, and natural ventilation inside the greenhouse, as well as blocking light and watering the mushrooms. The temperature inside the house during the day can be reduced to 15% without drying out the inside.
After the mushrooms have grown to a diameter of 5 to 6 cm, the humidity in the greenhouse should be below 70% and the room temperature during the day should be at least 15°C.
This is a method for cultivating dried shiitake mushrooms, which is characterized by maintaining the temperature at ~20°C to obtain thick-walled shiitake mushrooms with cracks on the surface of the cap. The second invention is a cultivation device used in the method for cultivating dried shiitake mushrooms, in which a transparent sheet made of synthetic resin is stretched outside the main body of the house constructed of pipe members, and a transparent sheet made of synthetic resin is stretched over the top of the main body of the house. In a shiitake mushroom cultivation house, which has a ventilation opening and an entrance/exit through which a crawler can enter and exit at the bottom, a winding mechanism is installed at the bottom of the main body of the house to roll up the lower part of the transparent sheet to a predetermined height for natural ventilation. At the same time, a net-like member is removably provided on the outside of the lower part of the transparent sheet to alleviate strong winds blowing into the house when the transparent sheet is rolled up, and a net-like member is removably provided above the space in the main body of the house for accommodating the Hoda tree. ,
An eaves shade material capable of sufficiently covering the space, a protective sheet made of non-woven fabric attached to the top of the eaves shade material so as to be openable and closable, and a water sprinkling device for sprinkling water on the Hoda trees below the eaves shade material. It is characterized by: In this invention, the low-temperature period refers to the period when shiitake mushrooms naturally grow from the mushrooms inoculated with shiitake fungus from around November to around March of the following year, when the average outside temperature is 15°C or lower. This invention is based on the basic conditions for cultivating shiitake mushrooms for dried shiitake mushrooms, in which high-quality shiitake mushrooms, which are used as raw materials for dried shiitake mushrooms, are cultivated in a controlled environment in a greenhouse during the low temperature period from November to March of the following year. This is what I am trying to do. This house is constructed in an arch shape with many pipe members, and has a ventilation opening at the top of the main front part, and an entrance and exit below it that is large enough for a crawler (transport vehicle) to enter and exit. Basically, it is no different from a greenhouse for cultivating fresh shiitake mushrooms, and there are no restrictions on the shape or material of the greenhouse, or even the position of ventilation holes or entrances. This house consists of a transparent sheet made of synthetic resin such as vinyl chloride resin that is removably stretched outside the main body of the house so as to cover the entire main body of the house. In order to achieve natural ventilation, the structure is such that it can be rolled up to a certain height in the height direction using a hoist. Inside the house, above the space for accommodating a large number of Hoda trees, there is an eaves shade material with breathability that can cover all the housed Hoda trees, and a non-woven fabric on the top of this eaves shade material. Each protective sheet is attached so that it can be opened and closed. These eaves shade materials and protective sheets are used to control the temperature inside the house, and open and close depending on the outside temperature. A water sprinkling pipe is provided below the eaves shade material to maintain a constant humidity of the wood, and water supplied from an external water supply equipment is sprayed toward the wood. , there are no special restrictions on these dimensions, shapes, or sizes. It is preferable to install Kakaru House in a relatively sunny place such as a former paddy field (idle field), a field, a field, or a deciduous forest near the grower's home. It is preferable to use varieties that emerge in the spring, and varieties that emerge in the spring or autumn that emerge during the low temperature period. The Hoda trees used for cultivation are fully ripened new Hoda trees (two summers after inoculation), oak oaks 2 to 3 years old (large diameter trees are 4 years old), and Quercus serrata 2 years old (large diameter trees are 3 years old). Preferably. After the outside temperature drops to 5°C or lower (for example, after several frosts), the tree is moved into the greenhouse and laid down. If the imported Hoda wood has a high moisture content, we will incorporate the Hoda wood into an armor type, cover it from the sun to create a ventilation effect, and then water it to provide water. At the same time as you bring it into the garden, sprinkle water on it so that it absorbs water and germinates. Once you have confirmed that the shiitake mushrooms have germinated, you can set the Hodagi in a gassho type when the humidity is high, or in an armrest type when the humidity is low, and then adjust the temperature and humidity inside the greenhouse by operating the mechanisms of each part of the house. The purpose is to adjust the ventilation and the degree of shading to the tree, and to water the tree appropriately as necessary to grow the desired product (for example, Hanadonko, Hanakoshin, thick-walled Koshin, etc.). While Shiitake mushrooms are growing, the humidity inside the greenhouse should be kept at least 70% (RH; the same applies hereafter) to prevent them from drying out, and the temperature inside the greenhouse should not exceed 15℃. After the cap of the germinated shiitake mushroom grows to a diameter of about 5 to 6 cm (about the size of a donko), maintain the night temperature in the greenhouse at 5°C or higher and the daytime temperature at 15 to 20°C, and The humidity is adjusted to 70% or less to maintain the plant in a dry state, and this dry state causes cracks to form on the cap, and the so-called flower donko, which are thick and have cracks in the cap, are collected. The collected shiitake mushrooms are then dried in a conventional manner to obtain dried shiitake mushrooms. After the first collection of shiitake mushrooms, various mechanisms are activated to apply cold and dry stimuli to the Hoda trees in the greenhouse, and then water is sprinkled again 30 to 50 days later to encourage the development and growth of shiitake mushrooms. A second sampling will be carried out. This second collection will be from late February to early March, and the outside temperature will often be higher than the first time, so the shiitake mushrooms obtained will be less donko, but more likely to be shiitake mushrooms, or thick shiitake mushrooms, with cracks in the caps. What you have will be taken. Once the second collection is complete, remove all the sheets covering the greenhouse to create an artificial hoda field, let the hoda trees grow during the high temperature period, wait for the temperature to drop, and use the above method again to harvest shiitake mushrooms during the low temperature period. Cultivation is carried out. [Effect] Generally speaking, the growth of shiitake mushrooms is greatly influenced by temperature, humidity, and light, and the optimum temperature for growth is between 7 and 7.
The temperature is 26℃ and the humidity is in the range of 60 to 90%.The higher the temperature, the thinner the mushrooms that can grow faster, and the lower the temperature, the larger, thicker, and better quality shiitake mushrooms will be, but it will take a long time to harvest. Deformations may occur depending on the variety. This invention aims to obtain shiitake mushrooms to be used as dried shiitake mushrooms by greenhouse cultivation, and for the purpose of producing dried shiitake mushrooms, it is necessary to cultivate them under a special controlled environment that is different from the cultivation of fresh shiitake mushrooms. It is something to do. In particular, since delicate adjustments are required through temperature and eaves/shade management, in order to facilitate this adjustment, eaves/shade material is placed inside the transparent sheet stretched outside the greenhouse, and A protective sheet made of breathable non-woven fabric is interposed between the eaves and shade material and the transparent sheet to form a triple-layered house, and the protective sheet and the eaves and shade material can be opened and closed. Light shielding and temperature control are performed. In addition to this special triple structure, the house is equipped with a water sprinkling pipe at the top of the space for storing the Hoda trees, which allows the housed Hoda trees to absorb water.
In addition, the lower part of the transparent sheet constituting the outermost coating can be opened and closed by rolling up, and temperature, humidity, and ventilation can be adjusted by natural ventilation. On the outside of the transparent sheet on this side, a mesh member with an appropriate mesh size is used to alleviate sudden changes in indoor temperature and humidity caused by strong winds blowing into the house when the transparent sheet is rolled up. This is a removably fixed device. With such a configuration, it is possible to control the temperature, humidity, and ventilation inside the greenhouse, as well as to manage the shading and watering of the Hoda tree, with great ease.
This allows Shiitake mushrooms to easily grow from the Hoda tree,
Moreover, the generated shiitake mushrooms can be easily grown for use as dried shiitake mushrooms while maintaining excellent quality and yield. Here, for the purpose of producing dried shiitake mushrooms, the case where shiitake mushrooms for dried shiitake mushrooms are produced using the cultivation method and cultivation device of the present invention, and the case where shiitake mushrooms for dried shiitake mushrooms are produced in a natural forest, Table 1 shows the results of a comparison of occurrences by brand of shiitake mushrooms. Further, the results of comparing the timing of harvesting of shiitake mushrooms according to the conventional cultivation method described above and the cultivation method of the present invention are shown in FIG. From these comparisons, it is clear that the present invention efficiently cultivates shiitake mushrooms for dried shiitake mushrooms.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the apparatus for cultivating dried shiitake mushrooms of the present invention and the method for cultivating dried shiitake mushrooms using this cultivation apparatus will be described in detail with reference to the accompanying drawings. A house 1 constituting this cultivation device is constructed using a large number of pipe members 2 to form an arch-shaped house body, and the outside of the house body is opened at a predetermined height and width at the lower left and right sides along the longitudinal direction. It is covered with a transparent sheet 7 made of vinyl chloride resin so that the
A relatively large entrance/exit 4 is formed through which people can go in and out, and a ventilation opening 3 is formed in the upper part of the entrance/exit 4. On both sides (longitudinal direction) of the house 1, side bars 5a and 5b are provided facing each other across the pipe member 2 at positions approximately 1.5 m from the ground, and a large number of side bars 5a and 5b are provided between the side bars 5a and 5b. They are connected at intervals by arch-shaped pipes 9, and a breathable white protective sheet 10 made of non-woven fabric is stretched over the arch-shaped pipes 9 in a manner that can be opened and closed freely along the longitudinal direction. Side rods 5 provided oppositely on the left and right inside the house 1
A, 5b, some of the arch-shaped pipes 9 are arranged at predetermined intervals in the longitudinal direction, and one end is connected downward from the center to an external water supply facility (not shown). Connected water sprinkling pipes 13 are installed vertically, so that water can be absorbed by a large number of Hoda trees housed in the house 1. Below the arch-shaped pipe 9, a plurality of filament bodies 11 made of steel wire are stretched in a mountain shape at intervals, and a large number of synthetic resin tapes made of vinyl chloride are woven into sheets on top of the filament bodies 11. The breathable black eave/shading material 12 constructed by this method is stretched so as to be openable and closable. The protective sheet 10 and the eaves shade material 12 are used to cover the Hoda tree housed in the house 1, and by moving one end of these in the length direction of the house 1, the cover is released and the upper space is opened. It is configured so that it can be opened. As shown in FIG. 2, the opened lower portions of the house 1 along the longitudinal direction are covered with transparent side sheets 8a and 8b made of the same material as the transparent sheet 7. side sheet 8a,
8b can be hoisted up to an appropriate height using hoists 6a and 6b, thereby allowing natural ventilation from the lower part of the house 1. On the outside of the side sheets 8a, 8b, in order to alleviate the strong wind blowing into the house 1 when the side sheets 8a, 8b are rolled up, a net-like member 14a made of synthetic resin with a coarse mesh of about 4 mm, 14
b is removably fixed. In this example, the house 1 is approximately 6 m wide x
It has a size of about 3.5 m in height x about 20 m in length, and the transparent sheet 7, the protective sheet 10 made of nonwoven fabric, and the eaves shade material 12 that make up the roof can all be removed as necessary. . In this embodiment, the left and right lower parts of the outside of the main body of the house along the longitudinal direction are not covered by the transparent sheet 7 but are covered by the side sheets 8a and 8b. Therefore, the transparent sheet 7 covers the entire left and right outer walls of the main body of the house.
Of course, the lower part of the winder 6a, 6b may be used to roll up the lower part to an appropriate height. In this case, the net-like members 14a and 14b are naturally provided on the outside of the transparent sheet 7. Karu House 1 is installed in a relatively sunny location, and the cultivation of shiitake mushrooms for dried shiitake mushrooms using this house 1 will be explained. When the outside temperature is 5.0
℃ or lower (when the outside temperature is 5℃ or lower, it is cold and it is extremely difficult to germinate), the seeds are carried in through the entrance 4 of the house 1 by a crawler and laid down inside the house 1. At this time, if the Hoda wood contains a lot of moisture, it is assembled in a shank shape, covered with sunshade to provide ventilation and suppress the effect, and then watered to absorb water. When the water content of the Hoda trees is low, the Hoda trees are brought into the house 1, stacked horizontally or laid down on the ground, and immediately sprinkled with water from the sprinkler pipe 13 to make the Hoda trees absorb water. Since the watering time for the entire Hoda tree is not constant, intermittent watering is performed for 3 days to ensure sufficient water absorption by watering for a fixed period of time. This intermittent water absorption is carried out once a day for 3 to 4 hours for 3 days, and after watering, a nonwoven fabric is hung to prevent drying. After that, if germination is confirmed from the Hoda trees, arrange the Hoda trees in a folded position (when the humidity is high) or in a folded position (when the humidity is low). At this time, the Hoda wood, which had a lot of moisture when it was brought in, will be reassembled as necessary. After that, each part of House 1 is operated to adjust the temperature, humidity, light shielding, and natural ventilation conditions to the conditions suitable for growth. ) The temperature inside House 1 is controlled to not exceed 15°C until the plants grow. The principle of cultivation in House 1 is to grow shiitake mushrooms without exposing them to rain, so transparent sheet 7
is normally kept in a fixed state. During the day, the white protective sheet 10 made of non-woven fabric is closed to cover the tree 15 in order to prevent the temperature rise inside the house 1 and avoid direct sunlight. However, if the temperature rises further, the eaves shade material 12 to strengthen the covering of the wood 15. If the temperature rises more significantly, open the ventilation port 3 and use the winders 6a, 6b to close the side sheets 8a, 8.
By rolling up the side sheets 8a and 8a, the temperature rise is prevented while the temperature rise is prevented while the inside of the house 1 is ventilated by natural ventilation.
Increase the winding of 8b to strengthen ventilation. At this time, since the net-like members 14a and 14b are fixed to the outside of the side sheets 8a and 8b, the strong wind does not blow into the house 1 with the same force, and the strong wind does not damage the husks and growing shiitake mushrooms. can be prevented. On the other hand, when the temperature inside the house 1 is low, the eaves shade material 12 is opened, the protective sheet 10 is closed, and the
is covered by this protective sheet 10, and when it is desired to further increase the temperature, the masking by the protective sheet 10 is canceled and the irradiation of sunlight is increased only with the outermost layer sheet 7, thereby suppressing the temperature rise inside the house 1. Measure. Particularly at night, the air temperature drops and the temperature inside the house 1 decreases, so all parts such as the ventilation opening 3, side sheets 8a and 8b, protective sheet 10, eaves shade material 12, etc. are closed to keep warm. Note that when the nighttime temperature decreases significantly, it is preferable to directly cover the wood 15 with a nonwoven fabric or the like to keep it warm. Until the diameter of the cap of the emerging shiitake mushroom grows to 5 to 6 cm (about the size of a donko), it is necessary to grow the shiitake mushroom so that it does not dry out. Maintain humidity by sprinkling water. Once the grown shiitake mushrooms have grown to the level described above, raise the temperature in House 1 to 15 to 20 degrees during the day.
Maintain at ℃ to promote growth. At that time, the humidity is controlled mainly by ventilation so that it is below 70%. If the humidity in House 1 is brought to a dry state through these operations, the shiitake mushrooms, which are about the size of Donko mushrooms, will grow to form a flower pattern on their caps in 3 to 5 days. By taking the shiitake mushrooms out and drying them in a separate drying device, dried shiitake mushrooms with excellent appearance and taste can be obtained. After the first collection of shiitake mushrooms (in this case, most of the shiitake mushrooms are the best), they are kept in the house 1 for 30 to 50 days as eaves shade material 1.
2 to create a shade, and by rolling up the side sheets 8a and 8b to provide ventilation, the Hoda tree 15 is given a cold and dry stimulus, and then the Hoda tree is watered again and the same process as above is carried out. A second collection of shiitake mushrooms will be conducted to develop and grow the mushrooms. Since this second cultivation is carried out from late February to early March, the temperature rises, and the resulting shiitake mushrooms have fewer donko mushrooms and more flower-stalked mushrooms such as koko and thick-walled shiitake. After collecting shiitake mushrooms for the second time, remove the transparent sheet 7, protective sheet 10, and eaves shade material 12 of the house 1, and also roll up the side sheets 8a and 8b at the bottom of the left and right sides of the house 1, and switch to an artificial hodder field. The Hoda tree is cured during the high temperature period, and after waiting for the temperature to drop, cultivation is carried out again using the method of the present invention. Note that this house 1 is constructed by removing the transparent sheet 7, side sheets 8a, 8b, protective sheet 10, and eaves shade material 12, pasting eaves shade material (not shown) on the pipe member 2, and installing the hoists 6a, 6b. The hem part of the eaves shade material can be opened and closed, and a transparent sheet (not shown) is stretched over the striated body 11 and a non-woven fabric (not shown) is stretched around the arched pipe 9. In addition to blocking hot air with the sheet,
The hot air generated between the upper eaves shade material and the lower transparent sheet can be discharged from the ventilation opening 3, so that the house can be effectively used as a fresh shiitake mushroom cultivation house for summer use. [Effects of the Invention] The method of the present invention is that when cultivating shiitake mushrooms, which are the raw material for dried shiitake mushrooms, inoculating the seed fungus that occurs in the low-temperature period, and cultivating the hoda trees in a hoda field using the usual method, the outside air is below 5 degrees Celsius. When the mushrooms mature, they are housed in a greenhouse, and the generation and growth of shiitake mushrooms is attempted by controlling the temperature, humidity, and natural ventilation in the greenhouse, blocking light from the tree, and sprinkling water.In particular, the growth of shiitake mushrooms is The inside of the greenhouse should not be allowed to dry out, and the temperature inside the greenhouse should not exceed 15℃ during the day.As the mushrooms grow, the diameter of their caps should grow to about 5 to 6 cm. is cultivated by maintaining the temperature inside the greenhouse at 15°C to 20°C during the day and keeping the humidity below 70%. By using this method, it is possible to obtain shiitake mushrooms that have superior quality as dried shiitake mushrooms and have a higher yield than naturally occurring shiitake mushrooms during the low temperature period from November to March of the following year. The stabilization of management can be significantly improved. On the other hand, the cultivation device used in the above-mentioned cultivation method has a transparent sheet that covers the outer periphery of the main part of the greenhouse, and can be rolled up and down freely, and a net-like member is provided on the outside of this rolled-up part to accommodate the Hoda trees inside the greenhouse. An eaves/shading material capable of sufficiently covering the space is placed above the space for the purpose of providing protection, and a breathable protective sheet is placed above the eaves/shading material so as to be openable and closable. It is equipped with a water sprinkling device that can sprinkle water on the area. The cultivation device with this structure improves the temperature retention performance and light shielding performance of the greenhouse by having a substantially triple structure of the transparent sheet, the protective sheet, and the eaves shade material. By having a structure that can be opened and closed, the adjustment can be made easy. In particular, this cultivation device has a water sprinkling function in the greenhouse in addition to the triple structure, and has transparent sheets that can be opened and closed at the bottom of both sides of the greenhouse to control temperature, humidity, and ventilation due to natural ventilation. It has the advantage of being able to maintain optimal conditions for growing shiitake mushrooms and obtaining shiitake mushrooms of excellent quality and high yield for dried shiitake mushrooms, which brings great benefits to the cultivation of shiitake mushrooms for dried shiitake mushrooms.
