[0002]

2. Description of the Related Art As a conventional water level adjusting device, there is, for example, one disclosed in Japanese Patent Publication No. 8-500974. That is, a first flow controller having a float to regulate the flow of water into the container, a second flow controller having a float to regulate the flow of air into the chamber of the first flow controller, and a first flow The controller has a ventilating device into the room, and when the water level in the container falls below a predetermined position, the water is caused to flow into the container to perform watering suitable for plant growth.

[0003]

However, since the conventional water level adjusting device is divided into the first flow controller and the second flow controller and has the respective casings, there is a problem that the device becomes large.

The present invention has been made in view of such conventional problems, and provides a water level adjusting device, a water level adjustable water receiver, and a water level adjustable planter which can reduce the size of the device. The purpose is to do.

[0005]

In order to achieve the above object, a water level adjusting device according to the present invention comprises a case, a first float, and a second float, and the case is hermetically sealed on its side surface and upper surface. The bottom surface is open and the bottom surface is open. It has a water inlet and a vent hole, and has a vent hole at the bottom of the side surface. The first float has a vent plug and can move up and down due to buoyancy in water and its own weight. Is provided in the upper part of the case, the vent plug opens the vent hole when the water level in the case exceeds a predetermined first water level, and the vent plug opens the vent hole when the water level is below the first water level. The second float has a side surface and an upper surface that are airtightly closed and a bottom surface that is open, and has a water injection plug that allows the second float to move up and down by the buoyancy of water and its own weight inside the case. Is provided, and the water level in the case is higher than the first water level. 2 When the water level is exceeded, the water injection plug closes the water injection port, and when the inside of the case is in a depressurized state, the water injection plug keeps the water injection port closed and the water level communicates the air vent with the atmosphere. It is characterized in that the water injection plug has a configuration of opening the water injection port when in a state of being made to be.

The water level adjusting device according to the present invention is installed at the inner bottom portion of a water receiver or the like, and the water inlet is used by connecting it to a water tank or the like located at a higher position.

When there is no water inside the water receiver, the second float descends by its own weight, and the water injection plug opens the water injection port. Therefore, water is injected into the case from the water injection port, and the water is collected in the water receiver. As the water level in the case rises, the second float rises due to buoyancy. When the water level exceeds a predetermined first water level, the first float rises due to buoyancy, and the ventilation plug opens the ventilation hole of the case. Therefore, water easily enters the case. When the water level exceeds the predetermined second water level, the second floating water injection plug closes the water injection port, and the water injection from the water injection port to the water receiver is stopped.

The water in the water receiver decreases due to the absorption and evaporation of water by the plants, and the water level in the case gradually decreases.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 to 9 show an embodiment of the present invention. As shown in FIGS. 1 to 6,
The water level adjusting device 1 includes a case 10, a first float 20, and a second float 30.

The case 10 is integrally formed of a box-shaped portion 11 and a lever accommodating portion 12, and has a side surface 13 and an upper surface 1.
4 is airtightly closed and the bottom surface 15 is open. As shown in FIG. 5, the lever accommodating portion 12 is narrower than the box-shaped portion 11 and has a step difference and is lower. The case 10 has a water injection port 16 on a side surface of an end portion of the lever accommodating portion 12. The case 10 has a ventilation hole 17 in the upper surface 14 of the box-shaped portion 11. As shown in FIGS. 1 to 3, the case 10 has a vent hole 18 extending along the installation location at the lower side surface of the lever accommodating portion 12. The height of the vent 18 is preferably 2-3 mm. The case 10 has a projecting portion 19 on the lower portion, and a hole for fixing a screw is formed in the projecting portion 19.

The first float 20 includes a lever 21 and a float 22.
It is made up of and. One end of the lever 21 is rotatably attached to a protrusion on the upper portion of the box-shaped portion 11 by a shaft portion 23. The lever 21 has a ventilation plug 24 at a position corresponding to the lower ventilation hole 17. Vent plug 24
Is made of a flexible material. The floating portion 22 is provided on the other end of the lever 21 and is placed on the upper side of the lever housing portion 12. A weight 25 is placed inside the floating portion 22.
Is provided, and the first float 20 is heavier than the second float 30. The first float 20 is capable of swinging in the vertical direction about the shaft portion 23 due to the buoyancy of the float portion 22 in water and its own weight. As described above, when the water level in the case 10 exceeds the predetermined first water level W1 (see FIG. 3), the first float 20 lifts the floating portion 22 by buoyancy and the ventilation plug 24 opens the ventilation hole 17. , When the first water level is W1 or less, a ventilation plug 2
4 is configured to close the vent hole 17.

The second float 30 includes a lever 31 and a float 32.
It is made up of and. The lower part of the lever 31 near one end is rotatably attached to the lower part of the inner side surface of the lever accommodating portion 12 by a shaft 33. The lever 31 has a water injection plug 34 at one end corresponding to the water injection port 16.
The water injection plug 34 is made of a flexible member. The floating portion 32 is provided at the other end of the lever 31 and is housed inside the box-shaped portion 11. Lever 31 and float 32
Has a side surface and an upper surface 35 that are hermetically closed and a bottom surface 36 that is open. The second float 30 is capable of swinging in the vertical direction about the shaft 33 due to the buoyancy of the float 32 in water and its own weight. The second float 30 has a predetermined second water level W in which the water level in the case 10 is higher than the first water level W1 (see FIG. 3).
2 (see FIG. 2), the floating portion 22 rises by buoyancy and the water injection plug 34 closes the water injection port 16, and when the inside of the case 10 is depressurized, the water injection plug 34 closes the water injection port 16 Is maintained, and the water injection plug 34 opens the water injection port 16 when the water level is in a state where the ventilation port 18 communicates with the atmosphere.

The water level adjusting device 1 is installed at the inner bottom of a water receiver or the like, and the water injection port 16 is used by connecting it to a water tank or the like located at a higher position with a flexible tube 37 (see FIG. 5). The water receiver may be any container that can store water. On the outer periphery of the water injection port 16, there is provided a protruding portion for tightly contacting the flexible tube 37 so that the flexible tube 37 does not come off and water does not leak. The flexible tube 37 is securely attached by screwing the fastener 38 into the water inlet 16.

A planter or the like is installed on the water receiver. When there is no water inside the water receiver, the second float 3
0 is descending by its own weight, and the water injection plug 34 opens the water injection port 16. Therefore, water is injected from the water injection port 16 into the case 10, and the water is collected in the water receiver. Case 10
As the water level inside rises, the second float 30 rises due to buoyancy. However, since the ventilation hole 17 is closed by the ventilation plug 24, the air inside the case 10 cannot escape. For this reason, the second float 30 does not rise completely, and the water injection plug 34 cannot close the water injection port 16.

When the water level exceeds the predetermined first water level W1,
The first float 20 rises by buoyancy, slightly behind the second float 30, and the ventilation plug 24 opens the ventilation hole 17 of the case 10. Therefore, the air whose pressure has been increased is discharged from the inside of the case 10 through the vent holes 17, and water easily enters the case 10. The second float 30 further rises as the water level rises. When the water level exceeds the predetermined second water level W2, the second float 30 hits the ceiling surface of the box-shaped portion 11 of the case 10 and stops rising. At this time, the water injection plug 34 of the second float 30 closes the water injection port 16 and the injection of water from the water injection port 16 into the water receiver is stopped.

Due to the absorption and transpiration of water by the plant, the capillary action of the soil in contact with the root of the plant, and the evaporation, the amount of water in the water receiver that has stopped pouring decreases, and the water level in the case 10 gradually decreases. . When the water level becomes equal to or lower than the predetermined first water level W1, the first float 20 descends by its own weight and is placed on the lever accommodating portion, and the ventilation plug 24 closes the ventilation hole 17 of the case 10. Therefore, even if the water level in the case 10 is lowered, the inside of the case 10 is in a depressurized state, the second float 30 does not descend by its own weight, and the state where the water injection plug 34 closes the water injection port 16 is maintained. The water level further drops and reaches the vent 18. At this time, the water level is 2-3 mm from the bottom of the water receiver.
Is only high. In this way, when the vent hole 18 is brought into communication with the atmosphere, air suddenly enters the case 10 through the vent hole 18, the second float 30 descends by its own weight, and the water injection plug 34 opens the water injection port 16. As a result, water is again injected into the case 10 from the water injection port 16 and the water is collected in the water receiver. By repeating the above operation, the water level can be adjusted.

It can be said that the repetition of the water level above and below is ideal for the growth conditions of plants. Water and air are continuously supplied to the soil, and microorganisms are activated to decompose organic matter. As a result, the cultivated vegetables have a good taste, the plants do not loop, and the water stress is not repeated. Therefore, the plant repeats ideal growth. Since the plant can grow even if the root does not grow more than necessary, it can be cultivated in a flowerpot smaller than a conventional flowerpot.

The water level adjusting device 1 includes a case 10 and a first
Since the float 20 and the second float 30 can be simply configured, the device can be downsized. Since the water level adjusting device 1 uses gravity and does not use power,
You can continue to adjust the water level as long as there is no failure.

As shown in FIG. 7, the water level adjusting device 1 may be installed on a lawn, a shrub plant, a roof plant, a roadbed, or the like.

A water receiver 40 capable of adjusting the water level using the water level adjusting device 1 has a water receiver main body 41 and the water level adjusting device 1 as shown in FIGS. 8 and 9, for example. The water receiver body 41 has two or four planters P1,
It has a mounting part for P2. The water level adjusting device 1 is provided on the inner bottom of the water receiver body 41.

The water receiver 40 capable of adjusting the water level is used by connecting the water injection port 16 of the water level adjusting device 1 to a water tank (not shown) or the like located at a higher position. Rainwater can be used as the water in the water tank. Further, a fertilizer suction path may be provided in the connection path between the water injection port 16 and the water storage tank. The water injection port 16 may be connected to a water faucet via a pressure reducing valve instead of being connected to a water storage tank. On the water receiver body 41,
Install planters P1 and P2. The planters may be of various sizes and shapes. Water level control device 1
Supplies water to the inside of the water receiver body 41 and adjusts the water level inside.

The water receiver 40 with adjustable water level is, for example,
For cultivation of commercial flowers, trees, especially vegetative trees, commercial vegetables, solar panels, dry batteries, 12V4A motors, water tanks, pressure tanks, fertilizer mixers, EC
2000 per 300 tsubo combined with FC meter
It is possible to grow tomatoes, melons, etc. in pots. The water receiver 40 with adjustable water level can be used as a cartridge type planter, a planter for flower pots, a cartridge type planter for vegetable cultivation (circular, square or other shape), a planter for producing roots of roots and foliage plants or any other plant growing plant. Can be applied.

FIGS. 10 and 11 show a water level adjustable water receiver according to another embodiment of the present invention. The water level adjustable water receiver 50 includes a water receiver main body 51, a water absorption mat 52, and a water level adjusting device 1.

The water receiver body 51 has an upper surface 54 having a groove 53. The water absorption mat 52 is disposed on the upper surface 54 of the water receiver main body 51, and the groove 53 is provided inside the water receiver main body 51.
It has a water absorption part 52a inserted from. Water absorption mat 52
Has a thin root preventive mat 55 thereon. The water level adjusting device 1 is provided on the inner bottom portion of the water receiver body 51 that communicates with the groove 53.

This water level adjustable water receiver 50 is used by connecting the water inlet 16 of the water level adjusting device 1 to a water tank or the like located at a higher position. A flowerpot P3 or the like is installed on the water absorption mat 52. The water level adjusting device 1 supplies water to the inside of the water receiver main body 51 to adjust the water level inside. The water absorbing mat 52 sucks up the water inside the water receiver main body 51 from the water absorbing portion 52a through the groove 53. Water absorption mat 52
In this, water is spread all over by capillarity. The water sucked up by the water absorption mat 52 is used by the plants in the flowerpot P3.

That is, the water that has entered from the sluice 56 through the flexible tube 37 reaches the entire groove through the groove 53, and then reaches the upper surface 54 of the water receiver main body 51 through the water absorbing mat 52 thereon. The flowerpot P3 is placed on the root-control mat 55. The flowerpot P3 is made of a non-woven fabric such as a thin hemp cloth and has good air permeability.
Therefore, the periphery of the flowerpot P3 is always in contact with the air, the air can be taken in from the surroundings, and the root enters inward, so that it does not appear outside.

The plant pot P3 absorbs the water contained in the root preventive mat 55 from the bottom in contact with the root preventive mat 55. Flowerpot P
The plant in 3 absorbs water from the bottom of the flower pot P3, and the absorbed water passes through the body of the plant and is evaporated from the leaves. The water in the water receiver 50 is absorbed by the roots of the plants from the water absorbing portion 52a in the groove 53, and the water level drops to the bottom of the groove 53. At that time, the water absorption mat 52 separates from the water, and air enters the water absorption mat 52. At that time, water enters the water inlet 16 of the water level adjusting device 1 from the water reservoir through the flexible tube 37. The water level adjusting device 1 distributes water as described above to adjust the water level. These operations are repeated depending on the condition of the plant. As described above, the water receiver 50 having an adjustable water level is an ideal water distribution system because there is no harmful water stress for plants and air enters the water absorption mat 52.

When a plant is produced, it is planted at a desired place or place through a production / growth stage from seedlings according to the purpose, and is ornamented or used. In that case, what is desired depends on what kind of environment the seedlings were grown in, as is called "seedling half-cropping", but depending on the subsequent management, it often makes a big difference.

Generally, at the seedling production stage, at the time of shipping,
The roots are often looped. This is a phenomenon caused by a lot of water stress due to lack of air at the production stage despite abundant water. Looped roots are not necessarily roots for subsequent growth and must be pruned or cut before planting.

What is desired in the production stage in the future is the following items 1 to 4. 1. The root is not looping. 2. Water is abundantly supplied and roots do not have to grow. 3. Air is always supplied and roots do not have to grow. 4. Since plants do not grow roots in a dry place, but want to root in a damp place, dry the outside of the pot and root it toward the damp inside. Therefore, the roots will crawl inward.

As a result, when transplanted, the roots are not plucked or cut off, so there is no pain in transplantation, and thereafter the plant starts to grow smoothly.

Although this is known, there has been no method for rational growth control. that is,
It can be said that this was because the idea of managing the water of plants was maintained because of the convenience of human beings to temporarily store water in pots and grow plants.

The water receiver 50 of which the water level can be adjusted creates a favorable environment for the growth of plants by the synergistic effect of the water level adjusting device 1 and the water absorbing mat 52, and thus produces a great economic effect.

Conventionally, a plant that does not grow is grown in a short period of time,
All measures have been taken to maintain current production levels in order to improve economic efficiency. As a result, the environment has been enormously deteriorated. Conventionally, chemical fertilizers that dissolve in water directly as fertilizer are used, which dissolves each time water is given,
It had flowed out of the bottom of the pot and reached groundwater. Alternatively, the liquid chemical fertilizer was directly mixed with the soil, and a large amount was applied to the soil through a sprinkler or the like for a considerable time. In the meantime, it is considered that a large amount of chemical fertilizer, which is far from the amount of transpiration of water in one pot, mixes with the groundwater together with water and reaches the sea, which leads to various pollution such as red tide generation due to eutrophication.

It is desirable to have the plants absorb all of the fertilizers and the like as they are supplied to the plants, instead of the conventional method. Fertilizers, etc. should not be drained underground with water. If the water receiver 50 with adjustable water level is used, it is possible to establish a production system in which only one plant can be distributed without spilling a drop of fertilizer, which is extremely good for the environment.

One water level adjusting device 1 per 1 square meter
By setting, 100 pieces in a 9 cm long pot,
Eighteen pots with a length of 20 cm can manage water unattended. This is an effective economic effect in the face of a shortage of young workers. Temporarily 300 tsubo (about 1000
Even per square meter), unmanned and without spilling a drop of water, water management of large quantities of plants can be done without power.

Conventionally, it has been common knowledge that water is pushed to increase the pressure and atomized from a nozzle to irrigate water. At one time, a large amount of water is pumped in, at one time the bottom water supply tray is filled with water from the bottom of the pot and then drained, and at some time the chemical substance or chemical fertilizer for disinfection and sterilization is dissolved in the water. And watering at the same time. Most of the water supplied in this way flows underground. Such water management is repeated. This is the actual situation at the plant production site, and although there was doubt about this, a solution to it was not considered.

The water level controllable water receiver 50 saves water, fertilizers and chemicals at many production sites, which have heretofore been impossible, and also protects plants without polluting groundwater. It fulfills the ideal physiological conditions, saves labor costs, and reduces costs. Therefore, not only is it good for the environment, but its economic effect is extremely large. The water level adjusting device 1, the flowerpot P3 made of a non-woven fabric, and the water absorption mat 52 can bring about a great effect on the growth of plants by being combined.

FIG. 12 shows a water level adjustable planter according to an embodiment of the present invention. The water level adjustable planter 60 includes a planter body 61 and the water level adjusting device 1. The planter main body 61 has a wall surface attachment portion 62 on the side surface on the back side. Water level control device 1
Is provided on the inner bottom of the planter body 61.
The water level adjusting device 1 is provided in a separate room from the planting part in order to facilitate maintenance. In addition, the water level adjusting device 1 can be removed and replaced for maintenance of plants.

The water level adjustable planter 60 is used by attaching the mounting portion 62 of the planter body 61 to the wall surface 63 of a building or the like. The water inlet 16 of the water level adjusting device 1 is connected to a water tank or the like at a higher position. The water level adjusting device 1 supplies water to the inside of the planter body 61 and adjusts the water level inside.

In the water distribution system using the water level adjusting device 1,
Since water and air (oxygen) are repeatedly distributed without interruption,
Plants are always supplied with what they need most. This eliminates water stress for all plants. On the other hand, human water management is very difficult and even impossible. Some people have made full use of their technical capabilities to rely on electrical methods for parts such as computer sensors that humans cannot understand. However, it requires various complicated structures and electrical wiring, and moisture is not desirable for them. Therefore, the structure including the maintenance becomes more complicated.

The water level adjusting device 1 does not have any electric device and uses natural gravity as it is. Therefore, the water level adjusting device 1 has an extremely simple structure and has few failures. A building covered with many plants is completed by directly attaching this simple water level adjusting device 1 to the wall of the building. In that case, the positive impact on the global environment is immeasurable.

By the way, on the wall surface, the following matters and countermeasures are assumed. 1. Select plants that can respond to climate change measures. 2. As a measure against changes in sunshine power, plants are selected by West Japan and East Japan. 3. As a measure against the size of rainwater, if it exceeds a certain amount, overflow it. 4. As a measure against changes in the amount of sunlight, change the plant depending on the region. 5. As a measure against seasonal changes, plant plants suitable for spring-autumn and autumn-winter. 6. As a measure against changes in wind force, use a net to prevent the wind from flying. 7. As a measure against changes in the wind direction, plant plants that will not be broken by strong winds and do not drop them by attaching brims.

By taking such measures, the water level adjustable planter 60 can cope with all weather conditions. Therefore, by using the planter 60 whose water level can be adjusted on the wall surface of the building structure, it becomes possible to green the entire building in one city where the greening is reduced. The water level adjustable planter 60 can be fixed to the wall surface of an existing building with a screw and can be installed in a new building.

By such greening of the wall surface, the entire building, building or the like can be greened. Therefore, it is possible to protect the wall material and the waterproof layer from ultraviolet rays and extend the durable life thereof, and it is not necessary to use expensive tiles such as bricks and pottery. It is possible to reduce the heat island environment, create a comfortable urban environment, and protect the global environment. For such greening, any plant can be planted, but it is preferable that the perennial plants that grow naturally be the basis of vegetation. As a result, it is possible to build a rough-release greening system that makes use of the natural environment. In addition, costs such as cooling and heating and energy can be reduced, and an increase in outside air temperature due to heat of vaporization can be suppressed. In addition, plants can store rainwater and delay the outflow of surplus water to prevent urban floods. It can absorb not only water but also dust and noise in the air. In addition, water level adjustable planter 6
The 0 may have a brim to prevent the plants from coming out due to strong wind.

Partition material 74
Allows water on the other side provided with the water level adjusting device 1 to pass on one side containing soil. The water is used by the plants in the planter.

The water level adjustable planter 70 has the following features. 1. It can collect rainwater. 2. A container is required to collect rainwater. Top plate 73
Is a rainwater accumulation container. 3. Only the rainwater enters the top plate 73. Therefore, it is preferable to provide the top plate 73 with an inclination. 4. Make a slope so that rainwater can enter the container. 5. The top plate 73 has a fixed volume, and rainwater of a volume larger than that does not enter. 6. When there is more rainfall, rainwater enters the through holes 77.

7. Plants are planted through the through holes 77 of the top plate 73. 8. Alternatively, after planting the plant, the top plate 73 is covered so that the plant comes out from the through hole 77 of the top plate 73. 9. To make it easier to plant a plant through the through hole 77, the through hole 77 should be wide enough to fit one hand (10.5
cm).

10. On the top plate 73, (1) prevent runoff of soil from strong rainwater (downpour), (2) prevent solidification of soil from strong rainwater (downpour), (3) in case of strong precipitation ,
Since the rainwater that has entered the through holes 77 travels along the leaves of the plant and the like, it is less directly affected by the strong rainwater (downpour) and can prevent the soil from solidifying.

11. The top plate 73 can suppress an increase in the surface temperature of the soil from strong heat radiation (solar radiation). 12. The roots of the plants growing under the top plate 73 are protected by the top plate 73, so mulching agents (bake chips etc.)
You don't have to use.

13. The through-hole 77 of the top plate 73 can also be put in a large pot for the saplings of the flowers and flowers that are currently the mainstream. 14. The through hole 77 of the top plate 73 can be inserted even if a pot chrysanthemum having a diameter of 12 cm is slightly distorted. If it is a small Prada chrysanthemum, there is no problem.

18. The numerous weed seeds mixed in the soil cannot be germinated because they are closed due to the top plate 73. 19. Weeds that start to germinate from the through holes 77 of the top plate 73
The plants are growing on top, resulting in lack of sunlight, and although germinated, photosynthesis is difficult to perform and the plants become weak. 20. Even if the weeds mixed in the soil later fill the gaps and start to grow, the soil does not solidify and is swelling, so it is easy to come out immediately. 21. Weed seeds that came later could be easily removed.

22. Rainwater accumulated on the top plate 73 goes down the flexible tube 37, enters the water level adjusting device 1 through the inner valve (adjusting coke). 23. The water level control device 1 is a gravity type that controls the water level. 24. Rainwater entering the water level control device 1 stops flowing at a constant water level. 25. Rainwater sucked into the soil is taken up into the plant by the roots of the plant. Note that a certain level of rainwater is in contact with the soil, and is absorbed into the soil by a capillary phenomenon (capillary).

26. The water taken up in the plant starts the transpiration action under sunlight. 27. The most necessary water content for plants is provided by the water level adjusting device 1 in abundant and constant water distribution without excess or deficiency, so that the water stress of the enemy of plants is eliminated. 28. At the same time, the required liquid fertilizer can flow in, so that it can grow smoothly.

29. Since the water level adjusting device 1 is a device capable of sending air (oxygen) at the same time, water, air, water,
The air repeats without interruption. The cycle of water distribution depends on all environmental conditions such as weather, temperature, season, wind strength, sunshine duration, humidity in the air, per day or shade, plant type, plant growth rate, plant size, etc. Even if they are different, each one will be according to its needs. Because of this, the plants grow surprisingly well.

32. This water level adjustable planter 70
Is equipped with ideal equipment for plant growth. For this reason, it can be said that it is the best device for plants because it can solve the blind spots of flower and green cultivation that could not be left by human hands.

30. The plant does not need to be rooted more than necessary, and looping (the root is repeatedly grown in search of water and nutrients and becomes a round roll in the root pot, for example, a flower pot flower) When I try to pull it out, the white roots are tightly entangled.) 31. This is a very favorable situation for plant cultivation. In other words, the plant can be grown without repotting. 32. For this reason, the number of roots is surprisingly small compared to the size and extension of the above-ground part. There is no need to put more soil than necessary, there is no need for more than the necessary size of the pot, and there is great significance in terms of price, economy, weight, and resources.

33. The outer pot is made by mixing the remaining clay, slaked lime, and water by the old “Tataki” method. 34. In the process of manufacturing, C
O2 is absorbed and unites in "Tataki". Therefore, environmentally friendly plants are planted using natural and environmentally friendly materials.

35. Since this planter stores rainwater once, it can be said that even a small amount can alleviate urban floods. 36. Now that the heat island phenomenon has been avoided, ideal greening can be achieved by using reactive water (rainwater) even with artificial pavement.

37. This device can be installed in any place (where it rains), and it is also possible to pour water with a bucket or the like only when the rain is insufficient. 38. This device can be converted into non-oxidizing water by FFC (water-soluble dimeric iron salt) and can be converted into rainwater which does not decompose.

FIG. 14 shows a water level adjustable planter according to another embodiment of the present invention. The water level adjustable planter 80 includes a water receiver 81, a water absorbing mat 82,
It is composed of a root preventive mat 83, a drainage layer 84, a water retaining layer 85, seeds 86, and an awning mat 87.

The water absorbing mat 82 is arranged on the water receiver 81 so as to be able to absorb the water inside the water receiver 81. The root preventive mat 83 is arranged on the water absorbent mat 82. The drainage layer 84 is arranged on the root protection mat 83. The water retention layer 85 is made of felt and is arranged on the drainage layer 84. The seeds 86 are sedum and moss seeds, and are arranged on the water retention layer 85. The shade mat 87 is arranged on the seed 86.

The water level adjustable planter 80 is for producing sedums necessary for roof greening. In recent years, the significance of greening not only the rooftop but also the sloping roof has been emphasized, and in Sendai City, Tokyo, and other local cities, it is obligatory to plant the rooftop or roof,
Furthermore, subsidies are issued to encourage greening. Therefore,
Plants that grow on the roof and do not grow on the ground, in other words, in the most harsh conditions possible, where plants, sedums and mosses that can survive in the last minute are grown on the roof. Even if weeds enter and germinate, the conditions are such that the weeds will die and the sedum and moss, which are more resistant to dryness, will survive because of the severe conditions on the roof. When cultivated, it is desirable that sedums and moss be produced on the ground under the same conditions as on the roof.

The water level adjustable planter 80 is suitable for the initial production of sedums and the like. Conventionally, when cultivating sedums, a water level adjustable planter 80 is installed in a house and sedums are sown. Set the same conditions as the roof as much as possible, that is, repeat drying. However, water was needed in the seedlings. Nonetheless, sedums are not suitable for overhumidity, and the timing of giving appropriate humidity and drying could not be automated only by human hands and cans. The water level adjustable planter 80 solves such conventional problems.

Even if it is easy to sow the sedum seeds, the maintenance growth after germination is difficult. Since sedums are delicate, irrigation by humans is especially difficult.
The planter 80 capable of adjusting the water level can reduce labor costs by being combined with the water level adjusting device 1 that accurately adjusts the water level. Also, along with the smooth growth of sedums, it is possible to develop the vitality that can withstand the harsh conditions on the roof that will eventually move. Furthermore, if FFC (water-soluble dimer iron salt) is used, it is possible to create a strong and pathogen-free nursery bed. When shipping the grown sedums, the shipping can be facilitated by winding or folding together with the water distribution layer.
