Description

  The present invention relates to a method and a house for cultivating shiitake mushrooms, and more particularly to a method for cultivating shiitake mushrooms and a house for cultivating shiitake mushrooms, which can easily manage the cultivation temperature and the cultivation humidity and can expect a large yield of shiitake.

  Shiitake has been cultivated in the past by burying shiitake fungus in a “wood” made of natural wood, and placing many of this bed in a dark forest. It was to wait for shiitake to grow as it was.

  In other words, Shiitake cultivation in a natural environment can not only cause the growth to deteriorate depending on the natural conditions, but it is also susceptible to pests such as slugs. Since it has become difficult in recent years to cut out from the plant, various improvements have been made for the shiitake cultivation as proposed in Patent Documents 1 to 3.

Japanese Patent Laid-Open No. 2003-143947, abstract, representative diagram Japanese Patent Laid-Open No. 8-103161, abstract, representative diagram Japanese Patent Laid-Open No. 9-210435, summary, representative diagram

  Patent Document 1 states that “in a soil pillar, the purpose is to effectively reuse industrial waste (waste soil) in a cultivation method that does not use any natural wood-based hodwood”. Shiitake cultivation has been proposed, and in this shiitake cultivation method, as shown in (1) of FIG. 5, in the process of producing gravel and sand for construction aggregates without using any natural wood or large sawdust etc. The main raw material is waste soil discharged as waste, and diatomaceous earth and withered weeds are added to this waste soil, and water is added to the wood acetic acid solution, potassium powder, potassium powder, phosphorus mineral powder, and carbon powder and stirred thoroughly. This kneaded product is put into a mold and heated and molded to form a cylindrical earth pillar. And, as shown in (2) of FIG. 5, in the “shiitake cultivation method” proposed in this patent document 1, “a cylindrical earth pillar is installed in a plastic house and a hole is made in the earth pillar. Inoculate shiitake mushrooms and humidify the house to grow shiitake mushrooms. "

  According to “Shibai Cultivation Method” of Patent Document 1, “Use of industrial waste [waste soil] is effectively used in a cultivation method that does not use any natural wood-based hodwood”. However, according to the examination of the inventors of the present application, it has been found that in shiitake cultivation, sufficient yield cannot be expected unless the temperature and humidity are carefully controlled to control the growth of shiitake. is there.

  For example, Patent Document 2 states that “in shiitake cultivation in a house, it is desirable in terms of growing shiitake to moisten the surface of the shiitake cultivation material with water in the cultivation process. It is made for the purpose of making it possible to "attach water to the surface of shiitake cultivation material without making the ground in the house moist". In addition, a “method and apparatus for attaching moisture to shiitake cultivation material” has been proposed.

  As shown in FIG. 6, in the “method and apparatus for attaching moisture to shiitake cultivation material” proposed in Patent Document 2, “apparatus 10 includes water tank 12, mist generation tank 14, A spray nozzle 16 and a second spray nozzle 18. A mist is generated in the mist generation tank 14 by an ultrasonic generator 36, and the mist is ejected from the first spray nozzle 16 to the outside. The diameter of the particles is set to 5 microns or less for mist drifting in the air, and high pressure air is ejected from the second spray nozzle 18 by the compressor 46, and the mist generation tank is generated by the negative pressure generated by the high pressure air. The water in 14 is simultaneously ejected from the second spray nozzle 18 to the outside, and the mist is ejected from the second spray nozzle 18 ".

  However, in the shiitake cultivation method of Patent Document 2, “it may be possible to attach water to the surface of shiitake cultivation material (hodaki)”, but the point found by the examination of the inventors of the present application, “ In shiitake cultivation, improvement of “a sufficient yield cannot be expected unless sufficient temperature and humidity control that affects the growth of shiitake mushrooms” has not been made.

  Patent Document 3 has been made for the purpose of “ensuring the environment in the house where the growth of plants and the like can be favorably obtained by improving the air supply state to the indoor space of the house for plant cultivation”. The invention relating to the “air conditioner” is described, and as shown in FIG. 7, the “air conditioner” is a “air conditioner that cools the interior of a house for shiitake cultivation. Supplying conditioned air into the house at the time of thermo-off.When the thermo is off, circulate the air in the house as about half the air volume at the time of the thermo-on. Ensure a safe environment. "

  However, since the "air conditioning apparatus" described in Patent Document 3 has a very complicated mechanism, it is used from the viewpoint of cost for shiitake cultivation that cannot be sold at such a high price. In addition to the fact that the inventor of the present application has examined, “The ability to control the temperature and humidity that influence the growth of shiitake mushrooms is not sufficient in shiitake cultivation. This is something that has not been improved.

  Therefore, the present inventors have determined that the temperature for improving the growth of shiitake is 15 ° C to 23 ° C and the humidity is 60% to 70% in shiitake cultivation. As a result of various studies on how to sufficiently manage the humidity, it has been found that the groundwater temperature is 15 ° C to 17 ° C in western Japan and 9 ° C to 11 ° C in northern Japan. Was completed.

  In other words, the object of the present invention is that the optimum temperature and humidity environment for shiitake cultivation can be formed at low cost regardless of the season, the running cost can be kept low, and the yield of shiitake is large. It is in providing the shiitake cultivation method and shiitake cultivation house which can be done.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
"A shiitake cultivation method in which a large number of shiitake cultivation bed 20 is arranged in the growth space R1 formed in the shiitake cultivation house 10, and shiitake 30 is grown from these bed trees 20,
The shiitake cultivation house 10 is composed of an inner house 11 that surrounds the growth space R1 and an outer house 12 that surrounds the entire inner house 11, so that sunlight is blocked by both the inner and outer houses 11, 12 and both Heat insulation between the growth space R1 and the outside world is performed by the separation space R2 formed between the houses 11 and 12.
Cooling in the growth space R1 is performed by spraying ground water toward the outer surface of the inner house 11 in the separation space R2,
Humidification in the growth space R1 is performed by spraying the growth water R1 in the groundwater,
Furthermore, the heating in the growth space R1 is also performed by deploying the solar heat absorbing material 13 on the outer surface of the outer house 12,
Shiitake cultivation method characterized in that the temperature in the growth space R1 is kept at 15 ° C. to 23 ° C., and the humidity in the growth space R1 is kept at 60% to 70%.
It is.

  That is, in the shiitake cultivation method according to the present invention, the temperature of the shiitake cultivation space is maintained at 15 ° C. to 23 ° C., and the humidity is maintained at 60% to 70% by sufficiently utilizing natural energy. Thus, cultivation of shiitake 30 is made at low cost and yield is increased.

  Therefore, in the shiitake cultivation method according to the present invention, as shown in FIG. 1 (1) and FIG. 2, first, the shiitake cultivation house 10 is divided into the inner house 11 surrounding the growth space R1 and the entire inner house 11. It is comprised by the outer house 12 which encloses, and the incidence | injection of sunlight in the growth space R1 is restrict | limited by these inner and outer houses 11 * 12. In other words, the inside of the daytime growth space R1 is made to be almost the same as the illuminance in the natural shiitake cultivation area (in the forest) by shading by the inner and outer houses 11 and 12.

  Further, a separation space R2 is formed between the inner and outer houses 11 and 12 constituting the shiitake cultivation house 10, and air is confined in the separation space R2 so as not to move by the wind. The trapped air insulates the growth space R1 from the outside. That is, in the shiitake cultivation method according to the present invention, the temperature in the growth space R1 changes rapidly due to the separation space R2 formed by the inner house 11 and the outer house 12, and by the light shielding by the inner house 11 and the outer house 12. Therefore, a certain degree of cold insulation or heat insulation is achieved without using a boiler or an air conditioner.

  On the other hand, in this shiitake cultivation method, the groundwater is sprayed to the outer surface of the inner house 11 by the groundwater sprayer 40 shown in FIG. 2, but the groundwater temperature is 15 ° C. to 17 ° C in western Japan throughout the year. Since it is almost constant at 9 ° C. to 11 ° C. in northern Japan, the temperature in the growth space R1 is cooled to a temperature close to this groundwater temperature. In addition, about groundwater, since it is scattered in the separation space R2, it cannot be overemphasized that it is sprayed on the outer surface of the inner house 11 in the stable state, without receiving the influence of a wind.

  By the way, the humidification in the growth space R1 is performed by spraying the ground water from the sprinkler 41 installed in the growth space R1. The spraying of the groundwater from the sprinkler 41 is originally performed for irrigation to the bed 20 arranged in the growth space R1, but the groundwater not used for irrigation is also sprayed in the growth space R1. As a result, the groundwater is evaporated in the growth space R1, and as a result, the humidification in the growth space R1 is also performed.

  The reason why the groundwater is used for irrigation from the sprinkler 41 is to cool the inside of the growth space R1 and use a common pump that is originally used to supply the groundwater to the groundwater spreader 40. This is because it is desirable to further reduce the cost when adopting the cultivation method.

  In the shiitake cultivation method according to the present invention, for example, when the outside air temperature is low as in winter, the solar heat absorbing material 13 is deployed on the outer surface of the outer house 12 so as to heat the growing space R1. It is. Although various things can be considered as the solar heat absorbing material 13, in the embodiment described later, the solar heat absorbing material 13 is made of a material such as a flexible vinyl sheet that can be easily developed on the outer surface of the outer house 12. In order to easily absorb light as heat energy, for example, a material colored “black” is employed.

  If such a solar heat absorbing material 13 is developed on the outer surface of the outer house 12 during the daytime when the sun goes out, the solar heat absorbing material 13 absorbs the solar heat and conducts it to the outer house 12 to warm the outer house 12. Thus, the inner house 11 and thus the growth space R1 are encased, and as a result, the inside of the growth space R1 is heated.

  Of course, sprinkling of the groundwater as described above and the development of the solar heat absorbing material 13 may be controlled according to the actually measured temperature and humidity in the growth space R1, and such control facilities and control devices are What is generally used may be used.

  As described above, by employing the shiitake cultivation method according to the present invention, the temperature in the growth space R1 is maintained at 15 ° C to 23 ° C, and the humidity in the growth space R1 is also maintained at 60% to 70%. As a result, Shiitake 30 is placed in a sufficient growth environment throughout the year.

  Here, it is necessary to keep the temperature in the growth space R1 at 15 ° C. to 23 ° C., because the “out” of the shiitake 30 becomes slow and worse when the temperature is 15 ° C. or lower. Yes, when the temperature exceeds 23 ° C., the “out” of the shiitake mushroom 30 is deteriorated. In addition, it is necessary to keep the humidity in the growth space R1 at 60% to 70%. The reason for this is that when the humidity is 60% or less, the “out” of shiitake 30 is slowed down to 70%. This is because the shiitake mushroom 30 that starts to rot begins to rot.

  Therefore, the shiitake cultivation method according to claim 1 can form the optimum temperature and humidity environment for shiitake cultivation at a low cost regardless of the season, can keep the running cost low, and the yield of shiitake. Can be made larger.

Further, in order to solve the above-mentioned problem, the means taken by the invention according to claim 2 will be described with reference numerals used in the description of the best mode to be described later.
“A shiitake cultivation house 10 in which a large number of shiitake cultivation bed 20 is arranged in a growth space R1 formed in shiitake cultivation house 10 and shiitake 30 is grown from these bed trees 20;
This shiitake cultivation house 10 is constituted by an inner house 11 surrounding the growth space R1 and an outer house 12 surrounding the entire inner house 11, and a separation space R2 is formed between these inner and outer houses 11, 12.
In this separation space R2, a groundwater sprayer 40 for spraying groundwater toward the outer surface of the inner house 11 is arranged,
A sprinkler 41 for spraying the groundwater is installed in the growth space R1,
Furthermore, the shiitake cultivation house 10 characterized in that the solar heat absorbing material 13 is installed on the outer surface of the outer house 12 so as to be deployable.
It is.

  That is, the shiitake cultivation house 10 according to claim 2 specifically realizes the shiitake cultivation method according to claim 1 described above, and the shiitake cultivation house 10 itself is composed of an inner house 11 and an outer house 12. It is constructed as a heavy structure, and in the separation space R2 formed by the inner house 11 and the outer house 12, and in the growth space R1 in the inner house 11 itself, it is 15 ° C to 17 ° C in western Japan throughout the year, It is intended to spray ground water at 9 ° C to 11 ° C.

  In the shiitake cultivation house 10 according to the present invention, as shown in FIG. 1 (1) and FIG. 2, first, the shiitake cultivation house 10 is composed of an inner house 11 surrounding the growth space R1 and an outside surrounding the inner house 11 as a whole. The house 12 is configured to limit the incidence of sunlight into the growth space R1 by the double structure of the inner and outer houses 11 and 12, and the daytime growth space R1 is just a natural shiitake cultivation area ( It is set to the same level as the illuminance in the forest.

  In addition, a separation space R2 is formed between the inner and outer houses 11 and 12 constituting the shiitake cultivation house 10 so as to confine air so that it does not move by the wind. This trapped air is the growth space. Insulation between R1 and the outside world is performed. That is, in the shiitake cultivation house 10 according to the present invention, the temperature in the growth space R1 is rapidly increased by the separation space R2 formed by the inner house 11 and the outer house 12, and by the light shielding by the inner house 11 and the outer house 12. Since it does not change, it is not necessary to use a boiler for heating or an air conditioner for cooling.

  In the shiitake cultivation house 10 according to the present invention, the solar heat absorbing material 13 can be deployed on the outer surface of the outer house 12 when the outside air temperature is low, for example, in winter. The solar heat absorbing material 13 is colored, for example, in black or close to it, and absorbs sunlight as heat energy, so that heating in the growth space R1 is performed.

  If such a solar heat absorbing material 13 is developed on the outer surface of the outer house 12 during the daytime when the sun goes out, the solar heat absorbing material 13 absorbs the solar heat and conducts it to the outer house 12 to warm the outer house 12. Thus, the inner house 11 and thus the growth space R1 are encased, and as a result, the inside of the growth space R1 is heated.

  On the other hand, in the shiitake cultivation house 10, since the groundwater sprayer 40 shown in FIG. 2 is used to spray groundwater toward the outer surface of the inner house 11, the temperature in the growth space R1 is increased to a temperature close to the groundwater temperature. Cool it. Further, humidification in the growth space R1 is performed by spraying and transpiration of the groundwater from the water sprinkler 41 installed in the growth space R1.

  In this shiitake cultivation house 10, although not shown in figure, the pump currently used in order to supply groundwater to the groundwater spreader 40 or the sprinkler 41 is used in common, and the said shiitake cultivation house 10 is comprised. We try to reduce the cost.

  In the shiitake cultivation house 10 according to the present invention, when the outside air temperature is low, for example, in winter, the outer surface of the outside house 12 is flexible and easily absorbs sunlight as heat energy. The solar heat absorbing material 13 formed of a material such as a vinyl sheet colored "" can be developed.

  Of course, sprinkling of the groundwater as described above and the development of the solar heat absorbing material 13 may be controlled according to the actually measured temperature and humidity in the growth space R1, and such control facilities and control devices are What is generally used may be used.

  As described above, by employing the shiitake cultivation house 10 according to the present invention, the temperature in the growth space R1 can be easily maintained at 15 ° C. to 23 ° C., and the humidity in the growth space R1 is also 60% to 60%. Since it can be easily maintained at 70%, the bed 20 for growing shiitake 30 is placed in a sufficient growing environment of shiitake 30 throughout the year.

  Therefore, the shiitake cultivation house 10 according to claim 2 can form the optimum temperature and humidity environment for shiitake cultivation at a low cost regardless of the season, and can keep the running cost low. The yield can be increased.

In order to solve the above-mentioned problem, the means taken by the invention according to claim 3 is the shiitake cultivation house 10 of claim 2,
“At least the gravel 50 is laid on the floor of the growth space R1, and the water shielding sheet 51 is laid on the lower side of the gravel 50”
It is.

  That is, in the shiitake cultivation house 10 according to the third aspect, the gravel 50 is laid on the laid water-impervious sheet 51 on the floor surface of the growth space R1 in the shiitake cultivation house 10 according to the second aspect.

  That is, in the shiitake cultivation house 10 according to the third aspect, a layer of gravel 50 is developed on the floor surface in the growth space R 1, and a part of the groundwater sprinkled from the sprinkler 41 is in the gravel 50. Soak into. Of course, since there is the water shielding sheet 51 under the gravel 50, the groundwater will not be absorbed into the ground through the gravel 50.

  As shown by the wavy line in FIG. 3, the groundwater soaked into the gravel 50 is evaporated in the growth space R1, thereby increasing the humidity in the growth space R1. In other words, the groundwater sprinkled by the water sprinkler 41 is not only used for irrigating the bed 20, but also used for securing the humidity in the growth space R1, and this groundwater is wasted. The use is lost.

  Therefore, the shiitake cultivation house 10 according to the third aspect exhibits the same function as that of the second aspect and can eliminate waste of groundwater used in the growth space R1.

As described above, in the present invention,
"A shiitake cultivation method in which a large number of shiitake cultivation bed 20 is arranged in the growth space R1 formed in the shiitake cultivation house 10, and shiitake 30 is grown from these bed trees 20,

It is a side view which shows another example of the shiitake cultivation house which concerns on this invention. It is an expanded sectional view (1) of the bed wood shown in patent documents 1, and a sectional view (2) of a house which uses the bed wood. It is a representative figure shown by patent document 2. FIG. It is a representative figure shown by patent document 3. FIG.

  Next, the invention according to each claim configured as described above will be described with respect to the shiitake cultivation house 10 shown in the drawings. The shiitake cultivation house 10 according to this embodiment substantially includes the shiitake cultivation of claim 1. Since the cultivation method has been embodied, the explanation of the shiitake cultivation method according to claim 1 will be omitted by detailing the explanation of the shiitake cultivation house 10 below.

  FIGS. 1 (1) and (2) show a front view and a side view of the shiitake cultivation house 10 according to the present invention. The shiitake cultivation house 10 surrounds a growth space R1 to be described later. This is a double structure composed of a house 11 and an outer house 12 covering the inner house 11. That is, in this shiitake cultivation house 10, as shown in FIG. 1 (1) and FIG. 2, first, the shiitake cultivation house 10 is composed of an inner house 11 surrounding the growth space R1 and an outer portion surrounding the entire inner house 11. The house 12 is configured to limit the incidence of sunlight into the growth space R1 by the double structure of the inner and outer houses 11 and 12, and the daytime growth space R1 is just a natural shiitake cultivation area ( It is set to the same level as the illuminance in the forest.

  The inside of this shiitake cultivation house 10 is as shown in FIG. That is, the inside house 11 of this shiitake cultivation house 10 is a growth space R1, and a lot of shelves 21 are arranged in this growth space R1, and shiitake fungus is embedded in each shelf 21. A large number of mortar trees 20 are arranged. The bed 20 may be “artificial” as proposed in Patent Document 1, or may be a natural tree embedded with shiitake fungi if possible. When natural wood is used, the shelf 21 may be unnecessary.

  In addition, a separation space R2 is formed between the inner and outer houses 11 and 12 constituting the shiitake cultivation house 10 so that the air is confined so as not to move by the wind, and the air confined in the separation space R2 is formed. Is designed to insulate the growth space R1 from the outside. That is, in the shiitake cultivation house 10 according to the present embodiment, the temperature in the growth space R1 is rapidly increased by the separation space R2 formed by the inner house 11 and the outer house 12, and by the light shielding by the inner house 11 and the outer house 12. Therefore, it is not necessary to use a boiler for heating or an air conditioner for cooling.

  On the other hand, in this shiitake cultivation house 10, as shown in FIG. 2, the groundwater spreader 40 which spreads groundwater toward the outer surface of the inner house 11 is installed in the separation space R2, and the growth space. A water sprinkler 41 is installed in R1. The groundwater sprayer 40 and the water sprinkler 41 can be supplied with groundwater by a common pump (not shown). This common pump is intended to reduce the cost in configuring the shiitake cultivation house 10.

  In this shiitake cultivation house 10, when the outside air temperature is low, for example, in winter, the outer surface of the outside house 12 is flexible and easily absorbs sunlight as heat energy, for example, colored "black". The solar heat absorbing material 13 formed of a material such as a vinyl sheet can be developed.

  The development of the solar heat absorbing material 13 is performed by various methods. In the example shown in FIG. 1, a winder 13 a is installed on the ceiling portion of the outer house 12, and the rope 13 b connected to the solar heat absorbing material 13 is wound or wound by the winder 13 a. The solar heat absorbing material 13 is developed by returning it. On the contrary, in the example shown in FIG. 4, the winder 13 a is installed on the lower side of the shiitake cultivation house 10 and the rope 13 b connected to the solar heat absorber 13 is connected to the ceiling portion of the outer house 12. The solar heat absorbing material 13 is spread on the ceiling of the outer house 12 by winding and unwinding the rope 13b by the winder 13a.

  Of course, sprinkling of the groundwater as described above and the development of the solar heat absorbing material 13 may be controlled according to the actually measured temperature and humidity in the growth space R1, and such control facilities and control devices are Generally used ones are used.

  Further, in the shiitake cultivation house 10 according to this embodiment, as shown in FIG. 2, gravel 50 is laid at least on the floor surface of the growth space R <b> 1, and a water shielding sheet 51 is laid below the gravel 50. It is like that. That is, in this shiitake cultivation house 10, the gravel 50 is laid on the laid water-impervious sheet 51 on the floor surface of the growth space R1.

  That is, in this shiitake cultivation house 10, the layer of gravel 50 is developed on the floor surface in the growth space R1, and a part of the groundwater sprayed from the sprinkler 41 soaks into the gravel 50. Thus, the sprayed groundwater is not absorbed into the ground through the gravel 50 by the water shielding sheet 51 under the gravel 50.

  As shown by the wavy line in FIG. 2, the groundwater soaked into the gravel 50 evaporates in the growth space R1, thereby increasing the humidity in the growth space R1. In other words, the groundwater sprinkled by the water sprinkler 41 can be used not only for irrigating the bed 20, but also for securing the humidity in the growth space R1, thereby eliminating the wasteful use of this groundwater. It is.

  As a result of growing shiitake 30 by employing a general artificial bed 20, it was 600 g in the conventional method, but according to the shiitake cultivation house 10 of the present invention, it was 750 g.

  By the way, the shiitake cultivation house 10 which concerns on a present Example has the thing of a West Japan specification, and the thing of a North Japan specification.

(For West Japan specification)
Since West Japan is relatively warm, the translucent material based on white is adopted as the vinyl sheet constituting the inner house 11 and the outer house 12 so as to easily reflect the sunlight in summer. With such a translucent vinyl sheet, the inside of the growing space R1 can be darkened like a forest, and the sunlight in the summer can be reflected, so that it is more than necessary in the growing space R1. There is no temperature rise.

  And in this shiitake cultivation house 10 of the West Japan specification, as shown in (1) of FIG. 3, in order to prevent the outer house 12 colored in white from reflecting most of the broken sunlight, The solar heat absorbing material 13 that can absorb sunlight as heat energy can be developed. In other words, winter solar energy can be used effectively. In addition, this solar heat absorption material 13 is expand | deployed on the outer house 12 by winding up the strip 13b connected to the said solar heat absorption material 13 with the winder 13a installed, for example on the ceiling of the outer house 12, and winding By rewinding the rope 13b by the take-up machine 13a, it is removed from the outer house 12 as appropriate.

(For North Japan specification)
Since northern Japan is relatively cold, a transparent sheet is adopted as the vinyl sheet constituting the inner house 11 and the outer house 12 so as to easily absorb sunlight. Even with such a transparent vinyl sheet, the inside of the growth space R1 can be darkened like a forest by making it double by the inner house 11 and the outer house 12. In addition, in order to be able to reflect sunlight too intensely in the summer, as shown in (2) of FIG. There is no temperature rise.
