Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to sphagnum cultivation means.
[0002]
[Prior art]
Sphagnum refers to a moss plant belonging to the Sphagnidae, and about 150 species per genus in the world and about 35 species in Japan are recorded. Sphagnum is known as one of the most economical value among moss plants, and in Japan it is often used mainly for horticulture.
[0003]
It is also known that sphagnum moss grows all over in the high-rise wetlands where peat develops on the surface of the water, and a peat layer mainly composed of sphagnum remains is formed below the surface. Yes. In such high-rise wetlands, a large amount of carbon dioxide is fixed for a long period of thousands of years, and it is known that it is a very important carbon dioxide absorption source on the present earth.
[0004]
At present, sphagnum marshlands represented by the above-mentioned high-rise marshes are being damaged rapidly for various reasons, and there is concern about the acceleration of global warming due to a decrease in the fixing power of global carbon dioxide. Yes.
[0005]
Under such circumstances, a means capable of easily cultivating sphagnum in large quantities is desired.
Currently, several methods have been reported as methods for cultivating sphagnum (Non-patent Documents 1 and 2). However, these methods must always be managed so that sphagnum does not dry out. There seems to be a problem with sex.
[0006]
In addition, in connection with this invention, the patent application regarding the sheet-like absorber using the outstanding absorptive power of dried sphagnum has also been made (patent document 1).

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an overall schematic view of a growth sphagnum 10. As shown in FIG. 1, each growing sphagnum is composed of a stem portion 11, a leaf portion and a branch portion 12. The present invention cultivates the sphagnum mosquito, in which only the stem part of the growing sphagnum is brought into contact with water, the leaf part and the branch part are separated from the water, and the growing sphagnum is cured in a state where it is not substantially in contact with water Based on the method, the field for sphagnum cultivation for performing this cultivation method is provided. Here, “substantially not in contact with water” means in particular that the stem part of the growing sphagnum in the main cultivation field is not brought into contact with water to be brought into contact. For example, when the main cultivation field is outdoors, it is not excluded that the leaves and / or stems of the growing sphagnum hit the rainwater due to rain or the like. However, a state in which the leaves and / or stems of the grown sphagnum are submerged for a long period of time due to rain or the like is not suitable for the growth of the grown sphagnum.
[0015]
It is a component of the main cultivation field.
(1) means capable of substantially preventing the leaves and / or branches of growing sphagnum moss from contacting water (hereinafter also referred to as non-contact means), and
(2) Means (hereinafter also referred to as contact means) that allow direct or indirect contact between the stems of growing sphagnum and water
Each means may be clearly separated in a specific mechanism, but both means may be included in the same mechanism or may be combined. The non-contact means of (1) is that the stems and / or branches of the growing sphagnum are not allowed to come into substantial contact with water, and the stems that are caused by the growth of the growing sphagnum later. It also means that the branches are also not substantially in contact with water.
[0016]
Hereinafter, typical aspects of the main cultivation field are listed.
<Aspect 1>
In aspect 1, (1) a water-impervious means is provided at the bottom, a side part is configured by a member provided with a water-permeable means, and an aquifer is disposed in a three-dimensional region having an open upper surface. And (2) water in contact with all or part of the side of the water storage part, and water infiltrates into the water storage part through the water-permeable means applied to this side part. This is a main cultivation field including a water storage unit capable of storing water as an essential component (hereinafter, also referred to as a main cultivation field 1).
[0017]
The main cultivation field 1 is suitable for use on a relatively large land such as a concrete surface such as a roof of a building or a fallow field. By constructing the main cultivation field at a desired location and cultivating sphagnum moss, formation of sphagnum marsh can be realized at the location. This makes it possible to remarkably suppress summer temperature rise on concrete surfaces such as rooftops of buildings as well as sphagnum harvest and carbon dioxide fixation by sphagnum cultivation.
[0018]
2 to 5 are drawings showing an embodiment of the main cultivation field 1.
As the field 1 for main cultivation, the aspect shown in FIG. 2 is one of the typical aspects, for example.
[0019]
In the cultivation field 20 shown in FIG. 2, i) water shielding means is applied to the bottom part 211, the side part 212 is formed of a member provided with a water passage port 213 which is a water permeable means, and the upper surface is opened. The aquifer 21 is disposed in a three-dimensional region bulkier than the maximum water level of the reservoir, and ii) the water 22 is all or part of the side of the aquifer 21 A water storage section 23 is provided that can store the water 22 so that the water 22 infiltrates into the aquifer 21 through the water inlet 213 provided in contact with the side section. . The bulk of the aquifer 214 in the aquifer 21 so that the aquifer 214 is always aspirated by the inflow of the water 22 and the water 22 is not covered on the aquifer 214. h (Although not particularly limited, considering the efficient use of water resources and the length of the stem of Sphagnum, it is preferably about 8 to 10 cm. The bulk h is the height of the side 212. The maximum water level of the water storage unit 23 is set to be lower than the height of the water reservoir 23. The adjustment of the bulk h and the maximum water level of the water storage part 23 can be performed, for example, by making the height h ′ of the outer wall 231 constituting the water storage part 23 lower than the bulk h of the aquifer 214. In this case, hh ′ is preferably 2 to 3 cm in consideration of the length of the stem of sphagnum moss and the extent that the aquifer 21 is not constantly covered with water. Further, the position of the water inlet 213 needs to be equal to or less than h ′, and is preferably near the bottom. By adopting such a configuration, the water level in the water reservoir 23 and the water level in the aquifer 214 of the aquifer 21 are equal, and this water level does not become higher than h ′ (excess water Flows out to the outside of the outer wall 231 of the reservoir 23), and in the vicinity of the upper surface of the aquifer 214, a portion that does not contact the direct water 22 having a depth of hh ′ is always secured. . In some cases, it may be preferable to make the height h ′ of the outer wall 231 higher than the side portion 212. In such a case, in order to make the water level in the water storage unit 23 lower by 2 to 3 cm than h, for example, a drain outlet is provided at a position corresponding to the set water level of the water storage unit 23 in the outer wall 231. It is possible to create a desired state by allowing excess water to flow out and / or controlling the water level in the water storage unit 23 using a water level sensor or the like.
[0020]
In addition, although the number of places of the aquifer 21 in this water storage part 23 may be one place, it can also provide two or more places as needed.
In the cultivation field 20, a hole 24 is provided in the aquifer 214 in the aquifer 21, and the stem 251 of one or more growing sphagnum 25 is preferably provided in the hole 24. In a certain state (the stalk part of the growing sphagnum is in a “settled state”) means that the stalk part of a plurality of growing sphagnum is aggregated in some form, In this case, the stems may or may not be entangled with each other, even if there is only one sphagnum sphagnum stalk. The depth at which this stalk can come into contact with the water 22 in the aquifer 214 as a single stalk can be made into a “solid state” by folding the part (2). ~ 3cm or more, preferably about 5cm) The growth of sphagnum moss is made efficient by curing the sphagnum sphagnum 25 while adjusting the water level of the aquifer 214 as described above with the leaves and / or the branches 252 exposed at the top. This can be done easily and simply [FIG. 3 (1)]. Further, by inserting only the stem portion 254 ′ from which the leaf portion and the branch portion 255 of the grown sphagnum moss are removed into the hole 24 ′, and curing the stem portion 254 ′, the growth starts from the stem portion 254 ′. In particular, the leaf portion and the branch portion can be obtained while being exposed from the aquifer 214. However, in order to perform curing from such a stem portion, it is necessary that a growth point is held in the vicinity of the tip portion of the stem portion 254 ′ exposed to the outside. It should be noted that whether or not a growth point exists in the stem portion can be determined by whether or not a greenish coloring is visually recognized in the vicinity of the cut surface of the stem portion. That is, if a greenish coloring is recognized, it is determined that the growth point has been secured, and if the green color is lost, it is determined that the growth point has been substantially lost. It is possible. Further, for example, in the aquifer 214, the seed plant 256 can be cured and the sunshine intensity can be adjusted by the shade caused by this.
[0021]
Moreover, as shown in FIG. 3 (2), on the aquifer 214 of the cultivation field 20, the growth sphagnum 24, preferably, the plants of the growth sphagnum 25 are stacked and placed. Also, the growth sphagnum 25 can be cured, and the growth sphagnum 25 can be grown so as to rise from the surface of the aquifer 214. However, the growth efficiency of the growth sphagnum 25 tends to be superior in the example of FIG. 3 (1).
[0022]
In this way, the aquifer 21 of the cultivation field 20 designed so that the water level does not rise above the aquifer 214 is cured by bringing only the stem portion of the growing sphagnum 25 into contact therewith, The stem part 251 comes into contact with the water affixed to the aquifer 214, and the cultivation farm 20 has a contact means. Conversely, the leaves and / or stems of the grown sphagnum 25 are exposed to the outside of the aquifer 214 and do not contact the water in the aquifer 214, and the cultivation field 20 is non-contact. Means are also provided.
[0023]
In addition, in the cultivation field 20 mentioned above, as a water-impervious means, making the raw material which comprises the bottom part 211 into a raw material which has water-imperviousness is mentioned. Examples of the material having the water shielding property include clay and plastic. Further, for example, a waterproof treatment may be applied to the bottom surface of a normal concrete surface or the like having poor waterproof properties. In addition, a material having waterproof properties such as a vinyl sheet may be laid on the bottom. Further, as the water permeable means, a water passage may be provided on the side as in this example, or the side itself may be made of a water permeable material such as porous concrete. The aquifer 214 is not particularly limited, and examples thereof include gravel and earth and sand. However, it is preferable to use a material composed of an inorganic substance as much as possible. From this point of view, gravel is often preferable to earth and sand in the general sense.
[0024]
The water source for supplying the water 22 to the water storage unit 23 of the main cultivation field 1 is not particularly limited, and tap water, ground water, lake water, river water, rain water, and the like can be selected according to circumstances.
For example, when the construction site is a fallow paddy field, the water of the existing irrigation canal can be used. For example, an artificial field 20 similar to that shown in FIG. 2 is constructed in the fallow rice field 300, and the water in the water storage section 23 is drawn from the water channel 333 for paddy fields, where the reservoir 332 provided with the sluice 331 is the water source. This can be used as the water 22 (FIG. 4: longitudinal sectional view). In addition, the water storage unit 23 of the cultivation field 20 stores water as it is and supplies it to the aquifer 21, but instead of this, for example, as shown in FIG. In addition, the water 22 from the water supply source 221 such as a water supply pump is retained therein, and the captured water is passed through a water-permeable material such as a weedproof sheet used as the side portion 212 (note that the bottom surface 211 is a waterproof layer), and by making it penetrate toward the aquifer 21, the required amount of water is reduced and water resources can be saved. This aspect 20 ′ is particularly preferably applied when constructing a cultivation field in an urban environment such as the rooftop of a building where tap water is often used.
[0025]
<Aspect 2>
Aspect 2 includes a water storage section that can store water and a suspension section that can suspend one or more growing sphagnum mosquitoes on the water storage section, and the suspension section suspends the stems of the growing sphagnum mosquitoes in the water storage section And a main cultivation field having a mechanism capable of exposing leaves and / or branches to the outside of the water storage unit (hereinafter also referred to as main cultivation field 2). In addition, if the water storage part of this aspect is a natural product, it corresponds to a natural water storage part such as a lake, a marshland, a river, a groundwater layer, etc. A relatively large artificial reservoir such as a water tank, pond, artificial river, artificial groundwater layer, pool, dam, rice field, etc .; and other artificial reservoirs manufactured based on a desired design.
[0026]
In FIG. 6 (longitudinal sectional view), the suspension part 41 is provided with a fitting hole 412 into which a stem 421 of a grown sphagnum moss can be fitted, and an opening part of the cylindrical water storage part 43. It is a lid-like member provided with a fitting mechanism 413 that can be fitted to a nearby edge to fit the suspension part 41 and the water storage part 43 [FIG. 6 (1)]. As shown in FIG. 6 (2), the suspended portion 41, in which the stem portion 421 of two or more growing sphagnum mosquitoes 42 (or one individual) is assembled, is fitted in the fitting hole 412, the water 44 The water sphagnum 42 is inserted into the opening of the water storage part 43 and the water sphagnum 42 is suspended from the water storage part 43 so that the water 44 and the stem 421 are brought into contact with each other. It can be performed. In this embodiment, the stem 421 is fitted into a cylindrical wire mesh member 413 as shown in FIG. 6 (3), for example, and is shaped as shown in FIG. 6 (4). It is also possible to perform this, and it is also possible to fit into a perforated cylindrical member 414 as shown in FIG. 6 (5) and to form as shown in FIG. 6 (6).
[0027]
In addition, for example, the hanging portion can be provided with a small hole 415 for the purpose of draining water and exchanging gas, and can be provided with a convex portion 416 on the outside [the hanging portion 41A in FIG. 7 (1): Vertical sectional view]. Further, a bag-like member 417 made of a water-permeable member such as a net-like member can be provided in the fitting hole 412 [the suspended portion 41B in FIG. 7 (2): longitudinal sectional view]. In this bag-shaped member 417, the growth sphagnum 45 with the stem portion gathered is inserted so as to come into contact therewith, and the growth sphagnum 45 is cured in the manner shown in FIG. [Fig. 7 (3): longitudinal section]. It is also possible to provide a plurality of fitting holes in one suspension part. FIG. 7 (4) is a lid type provided with a plurality of fitting holes 412 ′ and small holes 414 ′ that can be fitted and fixed to the edge of a box-shaped water tank 413 ′ containing water 44 ′. The suspension part 41 'is fitted and fixed to the edge of the water tank 713', and the growth sphagnum 42 'in a state where the stem part is gathered is fitted in each fitting hole 412' in the manner described above. It is drawing which showed the aspect which filled between the growth sphagnum 42 'with sand gravel. Thus, also in this aspect, it is possible to perform the curing of a plurality of Sphagnum cultivation units.
[0028]
In the field 2 for main cultivation in such a “hanging” manner, the leaf part, the branch part, and the stem part of the grown sphagnum are separated in the suspension part as described above, and the leaf part, the branch part, and the stem part are separated. Non-contact means for exposing the part to the outside and contact means for bringing the stem part into contact with water in the water storage part are provided.
[0029]
In the main cultivation field 2, transpiration of water in the water storage section can be suppressed by a suspension section that provides a sealing property such as a lid. This aspect is suitable for a) use on the roof, b) use indoors, and c) use on slopes and walls. With regard to a) use on the rooftop and b) indoor use, the sphagnum can be cured by performing the main cultivation field 2 in the above-described manner on the rooftop or indoors under appropriate conditions.
[0030]
On the slope, for example, in the cultivation field 470 shown in FIG. 8 (1) (longitudinal sectional view), the growing sphagnum 471 in a state where the stem portion is gathered on the slope 47 in a step-like manner, With the branch part exposed to the outside, the suspension part 472 is suspended in the water storage part 473, and only the stem part hangs down in the water in each water storage part 473. Each water storage unit 473 is in a state in which water can be supplied by the water supply pipe 474 in order to maintain a constant water level sequentially. Excess water is discharged to the outside through a small hole (not shown) provided in the suspension member 472.
[0031]
When the cultivation field 470 is used on a vertical wall surface (FIG. 8 (2)), for example, the individual water storage portions 473 ′ are locked to the wall surface 47 ′ by providing a locking mechanism, and the slopes described above are used. In the same manner as in, the water supply pipe 474 ′, which is a water supply means, allows water to be sequentially supplied so that the water level in the suspended portion 472 ′ is kept constant. Then, the growing sphagnum 471 ′ is suspended in the water storage portion by the suspension portion 472 ′, and the leaf portion and / or the branch portion is exposed to the outside so that only the stem portion is brought into contact with the water in the water storage portion.
[0032]
In these states, the growing sphagnum can be cultivated even on slopes and walls.
<Aspect 3>
Aspect 3 is a sphagnum cultivating field of an aspect in which a suspension mechanism of the sphagnum cultivating field of aspect 2 is provided with a mechanism that floats in the vicinity of the water surface in the reservoir (hereinafter also referred to as main cultivating field 3). .
[0033]
That is, in the main cultivation field 3, the contact between the water stored in the water storage section and the stem portion of the grown sphagnum mosquito is performed by the suspension part that can raise the grown sphagnum moss in the vicinity of the water surface by buoyancy. This is a field for sphagnum cultivation.
[0034]
The “mechanism capable of floating near the water surface by buoyancy” is preferably a mechanism using a material or instrument having a specific gravity smaller than that of water. As the material, polystyrene foam, wood, or the like can be used. Examples of the appliance include appliances containing a large amount of gas such as air, such as a floating ball and a floating ring.
[0035]
For example, FIG. 9 (1) (longitudinal sectional view) shows an outer frame 531 made of polystyrene foam as a suspended portion having a floating function in a water tank 52 with a drainage port 521 in which water 51 is filled. It is a drawing showing a state in which a large number of growth sphagnum 54 are placed on the bottom 532 of a low specific gravity container 53 provided with a body-made bottom 532. The low specific gravity container 53 floats on the surface of the water 51 due to its buoyancy with respect to the water, and the leaves and branches in the vicinity of the growing sphagnum 54 are not covered with the water 51 and only the stem part is submerged in the water. ing. By maintaining this state, the growth sphagnum 54 can be cured. When the buoyancy of the low specific gravity container 53 is insufficient, it is preferable that foamed polystyrene can be added as needed (5311). Further, a floating ball or the like can be used instead of or in combination with the expanded polystyrene. Further, as shown in FIG. 17 (2), a plurality of through-holes 551 are provided in the foamed polystyrene plate 55, and the growth sphagnum 54 is fitted therein, and the stem of the sphagnum moss is brought into contact with the water 51. It is also possible to cure growth sphagnum moss.
[0036]
The field 3 for main cultivation of such a “floating” aspect separates the leaf part, the branch part, and the stem part of the growing sphagnum in the suspension part with the above-described floating function, And a contact means for exposing the branch part and the stem part to the outside, and a contact means for bringing the stem part into contact with the water in the water storage part.
[0037]
The field for main cultivation of aspect 3 is suitable for a) use on a rooftop, b) use indoors, and c) use on a dam lake surface (artificial lake surface) or a pond surface. With regard to a) use on the rooftop and b) indoor use, sphagnum moss can be cured by performing the main cultivation field of this aspect on the rooftop or indoors under appropriate conditions. In particular, when this mode 3 is performed on a relatively small scale, it is possible to make a novel design by devising the design of the water tank and the polystyrene foam, which is also promising as an interior use.
[0038]
Moreover, c) The use on the dam lake surface (artificial lake surface) and the irrigation pond surface is one of the most promising use modes of the main cultivation field of this mode 3. In other words, by using this mode on the surface of a dam lake (artificial lake surface) or irrigation pond surface, it is possible to cover the lake surface etc. with a floating field of sphagnum moss, and to reduce the evaporation of water. It is possible to do without rehydration. In addition, it is considered possible to suppress the generation of harmful plankton due to eutrophication or the like by cultivating sphagnum moss to make the lake water acidic.
[0039]
FIG. 10 shows a large-scale embodiment of this aspect 3 as a conceptual diagram. FIG. 10 (1) is an enlarged conceptual diagram of the levitation unit 62 in the dam lake 61 or the like, and FIG. 10 (2) is an overall conceptual diagram. The eaves-like floating units 62A, B, C, D... Are reinforced by being separated by a wooden frame 621, and the bottom of each block 622A, B, C,. Is formed by being firmly stretched. On each of these blocks, a growth sphagnum 624 is placed on the growth point side in a frame unit 623A, B,... Made of a light material such as wood or styrofoam, in which a net is stretched on the bottom. This is placed on each block 622A, B, C,... While being locked by a pin 625. The levitating units 62A, B, C,... Are connected to the lake shore by wire ropes 63A, B, C,... A floating ball 632 is added to improve the buoyancy of the flying unit 62. Further, the floating units 62 are connected to each other by a hook-shaped passage 633 so that an operator or the like can easily move between the ribs. In this way, the plurality of frog-like levitation units 62 are kept floating on the lake water 64.
[0040]
By maintaining the state shown in FIG. 10, it is possible to cure the growing sphagnum 624 in the lake water on the dam lake 61. As described above, the transpiration of the lake water is suppressed simultaneously with the cultivation of the sphagnum moss. It can contribute to the conservation of the lake environment.
[0041]
【Example】
Examples of the present invention will be described below.
[Aspect 1 (Large-scale cultivation of sphagnum moss)]
We tried to cultivate giant sphagnum using a fallow paddy field in Ogatsu-gun, Akita, about 1,000 square meters. That is, the inside of the fallow paddy field is leveled, two wooden boards with a width of 8 cm, a length of 10 m and a thickness of 1.5 cm, and a width of 8 cm and a length of 3.6 m are 1 A wooden enclosure with a length of 10 m, a width of 3.6 m and a height of 8 cm was made using two .5 cm wood boards. Next, the bottom and side surfaces of the enclosure were all covered with a single waterproof sheet, and the enclosure was covered with the waterproof sheet, the width was 10 cm, the length was 9.8 m, and the thickness was 1. Using two 5cm wood boards, two 10cm wide, 3.4m long and 1.5cm thick wood boards, the longitudinal direction is 9.8m and the transverse direction is 3.4m The height was 10cm, and a slightly bulky enclosure was made. Next, the gravel was placed in the inner enclosure so that the gravel was completely worn out, and this was used as an aquifer. And the space | gap of an outer enclosure and an inner enclosure was made into the water storage part. Water was introduced from the irrigation channel located higher than the fallow paddy field into the reservoir using pipes. As a result, the reservoir is always filled with water and excess water is discharged outside the reservoir, while the aquifer enters the gap through the bottom and 8 cm of gravel from the bottom always remains in the water. After immersion, the part about 2cm from the top was constantly in a state where it was not in direct contact with water. The aquifer created in this way was used as a field for sphagnum cultivation.

Next, on this field, dig a hole with a diameter of about 5cm and a depth of about 5cm, and cut wild sphagnum so that the stem part is about 5cm, and bundle this stem part into a bundle. I inserted it inside. About 1 unit of such cultivation unit was provided on a 10 cm square on the field, and the field was left unattended.
[0043]
As a result, the sphagnum moss grew all over the field and grew to about 5-10 cm in one year [Fig. 11].
[0044]
[Aspect 2]
A commercially available sealed plastic container with a cylindrical lid has a central hole with a diameter of 5 cm in the vicinity of the center of the circular lid, and a number of small holes with a diameter of about 5 mm are provided around it. . In the center hole, cut the stems of the growing sphagnum mosquitoes obtained by the above-mentioned large-scale cultivation about 2 cm, and in this state, this center so that the leaves and branches are on the front side of the lid The lid was fitted into a container filled with water.
[0045]
The field for main cultivation thus created was left on the roof of a building in Tokyo from June to September. In this aspect, even if it becomes heavy rain, water does not cover the leaves and branches of the growing sphagnum for a long time, and conversely, when the water in the container is excessively reduced without raining, Tap water was supplied into the container.
[0046]
As a result, it was confirmed that the leaves and branches of the growing sphagnum, which were slight at the beginning, grew significantly to form a brute-like form (FIG. 12).
[0047]
[Aspect 3]
It is obtained by the above-mentioned large-scale cultivation in a small hole in a lightweight polystyrene base made of foamed polystyrene having a diameter of about 1.5 cm and a diameter of about 15 cm, provided with a through hole having a diameter of about 1.5 cm. Cut the stem of the growing sphagnum about 2 cm, fit it into these small holes, put the stem side down, and let it float above a sunny aquarium in Tokyo. , Left for 6-9 months. As a result, sphagnum leaves and branches were stretched on the lightweight substrate, and the disk was almost covered with sphagnum (FIG. 13).
