Description

  The present invention relates to a water supply device for planting and a plant using the same, which sucks water from a water source by capillary action and leaches water in a place suitable for water absorption of the plant without leaching water during transportation. The present invention relates to a water supply method.

  In particular, the present invention relates to a planting water supply device having a strong capillary force gradient and a planting water supply method using the planting water supply device.

  Moreover, this invention relates to the water supply method for planting which supplies water equally to a wide range of soil, and the water supply method for planting using the same.

  Many proposals have been made for supplying moisture to soil by capillary action.

  For example, Japanese Patent Application Laid-Open No. 10-56891 discloses an automatic water supply type plant cultivation container in which fibers for capillary action are arranged on the upper and lower parts of the culture soil, and water is supplied from a water source by the fibers for capillary action. .

  In view of the fact that the invention described in the above-mentioned JP-A-10-56891 cannot sufficiently supply oxygen to the roots of the plant in the previous hydroponics, oxygen can be sufficiently supplied to the roots of the plant. In addition, capillarity fibers are arranged at the upper and lower parts of the soil, and water is supplied to the roots of the plant together with oxygen using the capillary phenomenon.

  Japanese Patent Laid-Open No. 10-304783 discloses an apparatus for automatically supplying water to plants.

  The invention described in JP-A-10-304783 is intended to solve the problem that a conventional automatic water supply device that automatically opens and closes a water faucet by a solenoid valve or the like is large and expensive. Instead of placing a container for water in the lower part of the flower pot or the like, immersing one end of the water supply string in the water of the container and using the capillary phenomenon through the water supply string to the soil of the upper flower pot Water is automatically supplied.

  Japanese Patent Laid-Open No. 2003-80 describes a soil moisture regulation and supply device that can regulate the amount of moisture supply.

  In the invention described in the above Japanese Patent Laid-Open No. 2003-80, the automatic water supply by capillary phenomenon is unilaterally advanced to the water saturation point of the soil, resulting in excessive water supply, resulting in problems such as root rot. On the other hand, the adjustment mechanism which can adjust the permeation | transmission amount of a water | moisture content is provided in the middle of the water guide member which conveys water by capillary action.

  By the way, it is described that the fiber for capillary action described in the above-mentioned JP-A-10-56891 uses “felt-like fibers”.

  That is, the fiber for capillary action described in Japanese Patent Application Laid-Open No. 10-56891 discloses a string in which the fibers are entangled in a felt shape.

  In addition, the water supply string described in the above-mentioned Japanese Patent Laid-Open No. 10-304783 is disclosed in Japanese Patent Laid-Open No. 10-304783 as “for example, a round braid (8 × 8) having a diameter of about 4 mm, and the material is “Abundant water absorption”.

  In addition, in paragraph 0029 of the same publication, “as a string, a 100% rayon“ strike string ”(round braided braid) having an appropriate thickness (for example, a standard of 8 × 8), It was found that it is preferable to use a material that has been dyed as described above, ”paragraph 0030 states,“ This is that the string used is a rayon containing a large amount of cellulose components. This is because it has a high ability to suck up water by capillary action because it is weakly twisted or dyed, and is superior to others in that it is inexpensive. In addition, acrylic materials and water-repellent materials are poor in water absorption, so that they need to be used after having been once soaked in water. " There.

  That is, Japanese Patent Application Laid-Open No. 10-304783 discloses that a water supply string utilizing a capillary phenomenon is generally preferably water-absorbing. In addition, the string for water supply used with the technique of Unexamined-Japanese-Patent No. 10-304783 is a braided braid, and twists the yarn of 100% rayon.

As described in Paragraph 0009, the water guide member described in the above Japanese Patent Application Laid-Open No. 2003-80 is applied with moisture, heat, and pressure using a cotton fiber string, wool or other animal hair as a raw material. A string of felted cloth-like felt.
JP-A-10-56891 Japanese Patent Laid-Open No. 10-304783 JP 2003-80 A

  As described above, conventional capillary phenomenon fibers (Japanese Patent Laid-Open No. 10-56891), water supply strings (Japanese Patent Laid-Open No. 10-304783), water guide members (Japanese Patent Laid-Open No. 2003-80) ( Hereinafter, these are collectively referred to as “planting water supply device”) using fibers in which the fibers are irregularly entangled in a felt shape or twisted fibers such as a round braid. In general, it has been considered preferable to use a water-absorbing material.

  However, a water supply device for planting having water absorbency is convenient for first sucking up water from a water source, but once sucked up, the water supply device has a property of retaining the water inside. For this reason, the capillary force gradient was given to water and it was unsuitable for conveying water rapidly and far.

  Therefore, the conventional automatic water supply device for plants using the capillary phenomenon can supply water only to plants close to the water source. For example, as in the above prior art, a water container is provided in the immediate vicinity of the planter.

  However, if there is a water supply device for planting that has a strong capillary force gradient, water can be supplied to plants far from the water source, and sufficient water can be supplied to plants far away by the strong water transport force. Can do.

  Therefore, one problem to be solved by the present invention is to provide a planting water supply device that has a strong capillary force gradient and can sufficiently supply water to a plant far from a water source.

  In addition, as described in Japanese Patent Application Laid-Open No. 2003-80, the conventional water supply tool for planting is excessive until the soil becomes saturated with respect to the soil at a distance where water can be supplied by capillary action. It had the property of supplying water. Excessive water supply was rather inconvenient because it caused root decay of plants. Note that the technique disclosed in Japanese Patent Laid-Open No. 2003-80 is for preventing the above problem. However, the technique disclosed in Japanese Patent Application Laid-Open No. 2003-80 has a special water supply amount adjustment mechanism, and the structure is complicated.

  By the way, if you look closely, in general, when the end of the water supply tool for planting is buried in the soil, excessive water is leached at the base end of the buried part close to the water source, while the tip of the buried part far from the water source Then water leaching was insufficient. In other words, the root portion of the embedded portion of the water supply tool for planting supplies water excessively, which causes problems such as root rot, while the tip of the embedded portion lacks water supply and the plant withers, etc. Cause problems.

  If a predetermined amount of water to be transported can be leached evenly over the entire length from the embedded end of the water supply device for planting, it is said that water is supplied excessively on the one hand and water supply on the other hand is insufficient. The problem can be solved.

  Therefore, another problem to be solved by the present invention is that at the end of the water supply tool for planting in which water is leached, the water is evenly leached from the whole of the end so that the plant far from the water source can be removed. A moisture supply device for planting that can supply sufficient moisture, and that can suppress excessive leaching of water in a narrow range at the moisture leaching part close to the water source, and planting using the same It is in providing the water supply method for water.

Surrounding at least a part of a portion protruding from both ends.

The water supply device for planting according to the present invention is:

Both ends of the capillary transport portion protrude from both ends of the guide tube, and the leveling layer is formed around the portion of the capillary transport portion where the guide tube is mounted and the guide tube of the capillary transport portion. Surrounding at least a part of a portion protruding from both ends.

  The leveling layer surrounding at least a part of the capillary transport portion protruding from one end of the guide tube has a thickness gradient so that it is thick at the proximal portion of one end of the guide tube and thin at the distal portion. Can be like that.

  The leveling layer is composed of a plurality of layers, and in the portion of the capillary transport portion protruding from one end of the guide tube, the innermost layer surrounds the capillary transport portion up to the longest distance from one end of the guide tube, and the uppermost layer The capillary transport part may be surrounded from one end of the guide tube to different distances stepwise so that the capillary transport part is surrounded to the shortest distance from one end of the guide tube.

The water supply method for planting according to the present invention includes:
Capillary transport part formed by arranging non-water-absorbing fibers substantially in parallel, a moisture permeable leveling layer surrounding the capillary transport part, and a moisture impermeability attached to the outside of the leveling layer And a guide tube that can be bent freely, both end portions of the capillary transport portion project from both ends of the guide tube, and the leveling layer is mounted on the main body portion of the capillary transport portion and the guide. In the water supply method for planting using the water supply tool for planting surrounding at least a part of both ends of the capillary transport part protruding from both ends of the tube,
A first end portion of the capillary transport portion projecting from one end of the guide tube is used as a water source, and a second end portion of the capillary transport portion projecting from the other end of the guide tube is disposed substantially horizontally in the soil; Moisture is leached almost uniformly from the second end of the transport section over the entire length of the second end.

The water supply method for planting according to the present invention includes:
Capillary transport part formed by arranging non-water-absorbing fibers substantially in parallel, a moisture permeable leveling layer surrounding the capillary transport part, and a moisture impermeability attached to the outside of the leveling layer And a guide tube that can be bent freely, both end portions of the capillary transport portion project from both ends of the guide tube, and the leveling layer is mounted on the main body portion of the capillary transport portion and the guide. In the water supply method for planting using the water supply tool for planting surrounding at least a part of both ends of the capillary transport part protruding from both ends of the tube,
The end portions of the plurality of water supply devices are arranged in parallel with the soil, and the second end portions of the capillary transport portions of each water supply device are arranged continuously or partially overlapping in the length direction. Arranged so that the moisture is almost evenly leached from the second end of the capillary transport portion of each of the water supply devices over the length in which the second end of the capillary transport portion is continuously disposed. It is characterized by that.

  The water supply device for planting according to the present invention has a capillary transport part in which non-water-absorbing fibers are arranged substantially in parallel at the center part, a water-permeable leveling layer is provided on the outer side, and moisture is provided on the outer side. An impermeable and flexible guide tube is provided.

  Since the above-mentioned capillary transport part is a structure in which non-water-absorbing fibers are arranged substantially in parallel, water is conveyed by the gap between the fibers that run side by side, thereby having a strong capillary force gradient and quickly Can be transported.

  However, in the water supply device for planting having only the capillary transport part, the flow of water is often interrupted in the middle, and there is a part that transports water quickly in the capillary transport part alone, but it is interrupted in the middle Eventually we cannot carry water far away.

  The leveling layer of the present invention covers the periphery of the capillary transport section, sucks the water transported by the capillary transport section, slowly permeates water while holding the water abundantly inside, and transports water in the capillary transport section. If there is an interrupted part, water is supplied from the leveling layer to the capillary transport part and transported again by the capillary transport part. ).

  With the leveling layer, the capillary transport is wetted with water over a long part, so that water can be transported by long-distance capillary action.

  As described above, the water supply device for planting of the present invention has a strong capillary force gradient due to the complementary action of the capillary transport part and the leveling layer, transports water quickly and far, and is a plant far from the water source. Sufficient water can be supplied.

  In addition, the leveling layer of the present invention prevents most of the water from leaching out from the portion near the water source at the end of the capillary transport portion protruding from the guide tube embedded in the soil, and leaches out the water. It has an action of spreading water uniformly over the entire end portion of the capillary transporting portion that extends to the tip portion and protrudes from the guide tube (leveling action of water leaching).

  That is, the leveling layer of the present invention has resistance to water permeation, and water suddenly leaches into the soil from the base end portion of the end of the capillary transport portion protruding from the guide tube embedded in the soil. While maintaining water inside, it has the property of permeating water while allowing water to penetrate to the leveling layer at the tip of the capillary transport part protruding from the guide tube and from the tip of the capillary transport part. Water can be leached.

  With the leveling layer of the present invention, the water supply device for planting of the present invention can be evenly leached from the entire end of the capillary transport part protruding from the guide tube embedded in the soil.

  In the end portion of the capillary transport portion protruding from the guide tube, the leveling layer has a thickness gradient so that it is thick at the proximal portion of one end of the guide tube and thin at the distal portion. According to the water supply device for planting, the water leaching resistance is large at the proximal part of one end of the guide tube because of the large thickness of the leveling layer, and the leveling layer is thin at the distal part. Small leaching resistance. As a result, there is less water leaching at the proximal portion of one end of the guide tube, and more water is leached at the distal portion, and water is discharged from the entire end of the capillary transport portion protruding from the guide tube embedded in the soil. Can be leached evenly.

  The leveling layer has a plurality of layers, and at the end of the capillary transport portion protruding from the guide tube, the innermost layer surrounds the capillary transport portion from one end of the guide tube to the longest distance, and the uppermost layer is the guide tube. The planting water supply device of the present invention in which the leveling layer surrounds the capillary transport part from one end of the guide tube to a stepwise different distance from one end of the guide tube so as to surround the capillary transport part from one end of the guide tube to one end of the guide tube. In the proximal part, water leaching resistance is large because the number of leveling layers is large and the whole thickness is large, and water leaching is large in the distal part because the number of leveling layers is small and the whole thickness is thin. Resistance is small. As a result, there is less water leaching at the proximal portion of one end of the guide tube, and more water is leached at the distal portion, and water is discharged from the entire end of the capillary transport portion protruding from the guide tube embedded in the soil. Can be leached evenly.

  In the water supply method for planting according to the present invention, a moisture permeable leveling layer is attached to the outside of a capillary transport part in which non-water-absorbing fibers are arranged substantially in parallel, and both ends of the capillary transport part are impermeable to water. Capillary tube that protrudes from a guide tube embedded in the soil and has a large capillary force gradient and can transport water quickly to a distance by using a water supply tool for planting that protrudes from both ends of a natural guide tube Water can be evenly leached from the entire end of the transport section.

  In addition, the end portions of the plurality of water supply devices are parallel to the soil, and the end portions of the capillary transport portions of each water supply device protruding from the guide tube are continuously or partially overlapped in the length direction. According to the water supply method for planting of the present invention arranged so that water is uniformly leached from the end of the capillary transport part of each water supply tool, and the end of the capillary transport part is in the length direction. Therefore, water can be evenly supplied to a wide range of soil.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows planting using the planting water supply device of the present invention.

  In FIG. 1, the code | symbol 1 has shown the water supply tool for planting by one Embodiment of this invention. Reference numeral 2 denotes a plant, reference numeral 3 denotes a planter, reference numeral 4 denotes soil, reference numeral 5 denotes a water container, and reference numeral 6 denotes water.

  The water supply tool 1 for planting has a capillary transport part formed by disposing non-water-absorbing fibers substantially in parallel at the center, and has a water-permeable leveling layer around it so as to wrap it. In addition, a guide tube that is impermeable to water and bendable is provided around it.

  FIG. 2 shows the structure of the water supply tool 1 for planting.

  FIG. 2 shows an end of the planting water supply tool 1 embedded in the soil 4.

  In FIG. 2, reference numeral 7 denotes a capillary transport section, reference numeral 8 denotes a leveling layer, and reference numeral 9 denotes a guide tube.

  The capillary transport part 7 is a structure in which non-water-absorbing fibers are arranged substantially in parallel, and fibers such as polyethylene, polypropylene, vinyl chloride, acrylic and polystyrene can be used as the fibers.

  The fibers of the capillary transport section 7 are very thin, and in FIG. 2, the fibers are shown thicker for the purpose of illustration, but those having a thickness of 5 to 20 denier can be preferably used.

  Moreover, as a density of the capillary transport part 7, when a polypropylene is used, for example, the thing of 100-200 grams / meter (g / m) can be used preferably.

  A leveling layer 8 is attached around the capillary transport section 7 having the above configuration.

  The leveling layer 8 is a moisture permeable layer. A felt-like fiber layer, a nonwoven fabric, etc. can be used as a moisture permeable layer. The leveling layer 8 of this embodiment uses a synthetic resin nonwoven fabric, for example, a polyester nonwoven fabric.

  In FIG. 2, the leveling layer 8 surrounds only a part of the end of the capillary transport part 7 protruding from one end of the guide tube 9, but the leveling layer 8 is the end of the guide tube 9. It is also possible to surround the entire end including the end face of the capillary transport part 7 protruding from the end.

  The guide tube 9 is made of a moisture-impermeable material, for example, a synthetic resin (polyethylene, polypropylene, vinyl chloride, polystyrene, etc.), and is flexible. However, when the guide tube 9 is bent, it is preferable that the cross section of the curved portion is not flattened and maintains a circular shape.

  Here, referring back to FIG.

  As shown in FIG. 1, in the planting water supply device 1, both end portions of the capillary transport portion 7 protrude from both ends of the guide tube 9 (both end portions of the capillary transport portion 7 protruding from the guide tube 9 are leveled. The whole is covered by layer 8). In use, the first end 7a of the capillary transporting part protruding from the guide tube 9 is in the water 6 of the water source, and the second end 7b of the capillary transporting part protruding from the other end of the guide tube 9 is almost in the soil 4. Embed horizontally.

  By arranging the water supply tool 1 for planting as shown in FIG. 1, water is sucked up from the first end portion 7a of the capillary transport section and conveyed through the guide tube 9, and the second end section of the capillary transport section. It reaches 7b and leaches into the soil 4. Here, it should be noted that according to the present invention, water can be evenly leached from the entire second end 7b of the capillary transport portion by the action described later, and sufficient water can be supplied to a wide range of soils. It can be done. A region 10 in FIG. 1 indicates a region where the soil is wet (wet soil region 10). As shown in FIG. 1, according to the present invention, the wet soil region 10 is leached extensively around the second end 7b of the capillary transport section.

  Hereinafter, the effect | action which water leaches out uniformly from the embedding edge part of the water supply tool for planting in this invention is demonstrated using FIG.

  In FIG. 3, the code | symbol 7 has shown the capillary conveyance part, the code | symbol 8 has the leveling layer, the code | symbol 9 has shown the guide pipe | tube, and the code | symbol 10 has shown the wet soil area | region.

  FIG. 3 (a) shows a case where the capillary transport part 7 protrudes from the end of the guide tube 9 and the end of the capillary transport part 7 is buried and is directly in contact with the soil, as in the conventional water supply tool for planting. is there.

  FIG. 3 (b) shows a water supply tool for planting in a mode in which the entire peripheral surface of the end protruding from the end of the guide tube 9 is surrounded by the leveling layer 8.

  FIG. 3C shows a water supply tool for planting in a mode in which a part of the end protruding from the end of the guide tube 9 is surrounded by the leveling layer 8.

  As shown in FIG. 3A, when the capillary transport part 7 is in direct contact with the soil, a large amount of water is generated from the portion near the end of the guide tube 9 in the capillary transport part 7 protruding from the end of the guide tube 9. And the water does not reach the distal portion of the end of the guide tube 9.

  As a result, as shown in FIG. 3A, the wet soil region 10 extends near the end of the guide tube 9, while the soil is not wetted at the tip of the capillary transport portion 7 far from the guide tube 9.

  Since a large amount of water is supplied in the wet soil region 10 near the end of the guide tube 9, the water is saturated, while the soil is dry at the tip of the capillary transport unit 7.

  In the case of FIG. 3B, the entire capillary transport portion 7 protruding from the end of the guide tube 9 is covered with the leveling layer 8.

  The leveling layer 8 becomes resistant to water permeation and allows water to permeate toward the tip of the capillary transport part 7. As a result, as shown in FIG. 3B, a relatively large amount of water leaches out at the base end portion of the end of the capillary transport portion 7 protruding from the end of the guide tube 9, but the degree of leaching is as shown in FIG. Less than in the case of a). The wet soil region 10 in the case of FIG. 3 (b) extends to the tip of the end of the capillary transport part 7 protruding from the end of the guide tube 9, and water from the entire end of the capillary transport part 7 protruding from the guide tube. Can be seen leaching. In addition, leaching water uniformly from the entire end of the capillary transporting portion 7 in this way is referred to as “water leaching leveling action” in this specification.

  In the case of FIG. 3C, a part of the capillary transport portion 7 protruding from the end of the guide tube 9 is covered with the leveling layer 8. In this case, the capillary transport section 7 is in direct contact with the soil 4 at the end of the capillary transport section 7.

  Generally, water easily leaches out in a portion where the capillary transport part 7 is in direct contact with the soil 4. On the other hand, although water is leached even in the portion covered with the leveling layer 8, the leveling layer 8 becomes a resistance to leaching. Further, the water leaching portion is widened by the leveling layer 8. In this way, the leveling layer 8 equalizes water leaching.

  As a result, as shown in FIG. 3 (c), the wet soil region 10 that expands in the vicinity of the end of the guide tube 9 gradually narrows as it goes to the tip of the capillary transport section 7, and the end of the capillary transport section 7 becomes narrower. The wet soil region 10 is expanded again in the portion directly touching the soil.

  Even in the case of FIG. 3C, it can be seen that water leaches out from the entire end portion of the capillary transport portion 7 protruding from the guide tube as compared with the case of FIG.

  As described above, in the portion where the capillary transport portion 7 is directly embedded in the soil, water is leached frequently, while in the portion where the capillary transport portion 7 is covered with the leveling layer 8, the leveling layer 8 is formed. It becomes water leaching resistance and widens the water leaching part, and the water leaching is leveled. In the present invention, as shown in FIGS. 3B and 3C, the wet soil region 10 can be appropriately adjusted by appropriately adjusting the portion surrounded by the leveling layer 8.

  The leveling layer 8 of the present invention has an effect of promoting the leveling of water leaching as described above when it is between the capillary transport section 7 and the soil. When it is in between, it has the effect of preventing the interruption of water conveyance.

  When the capillary transport part 7 is formed of parallel fibers as in the present invention, water penetrates by capillary action in the gaps between the parallel fibers, and is rapidly conveyed.

  However, capillary permeation between parallel fibers is less likely to be transported again when the spacing between the fibers increases and air is interposed, at which time water moves to the gap between the other fibers and is transported again.

  On the other hand, the leveling layer 8 of the present invention covers the periphery of the capillary transport part, absorbs the water transported by the parallel fibers, and slowly permeates the water while holding the water abundantly inside. If there is a portion where water conveyance is interrupted between the parallel fibers of the capillary transport part 7, water is supplied from the leveling layer 8 to the capillary transport part 7, and the water transport is started again in the capillary transport part. The conveyance of water in the capillary transport part 7 is maintained for a long distance without interruption. In addition, the effect | action which spreads the part which produces a capillary phenomenon in the capillary transport part 7 which consists of a parallel fiber in this way is called "leveling effect | action of water conveyance" in this specification.

  As described above, in the water supply tool 1 for planting according to the present invention, the leveling layer 8 maintains the water transport in the capillary transport section 7 and transports the water quickly and in large quantities by the capillary transport section 7. That is, the water supply tool 1 for planting according to the present invention can supply sufficient water to a distance away by the complementary action of the capillary transport part 7 and the leveling layer 8.

  Further, the leveling layer 8 of the present invention has the function of maintaining the water transport of the capillary transport part 7 (water transport leveling function) when the guide member 9 is inside the guide tube 9 by the same member. The portion of the capillary transport portion 7 protruding from the tube 9 serves to equalize the water leaching (leveling action of the water leaching), has two actions by one member, and allows the water to be efficiently removed by a simple structure. It is possible to realize the water supply tool 1 for planting that supplies up to.

  When the leveling layer 8 is interposed between the capillary transport portion 7 and the soil, the greater the thickness, the greater the resistance to water leaching. Utilizing this fact, the leaching of water at the end of the capillary transport part 7 protruding from the guide tube 9 can be further equalized.

  FIG. 4 shows another embodiment of the water supply device for planting according to the present invention.

  The water supply tool 11 for planting shown in FIG. 4 has a plurality of leveling layers 8a, 8b, 8c.

  In FIG. 4, the same parts as those in FIG. 2 except for the water supply tool for planting and the leveling layer are denoted by the same reference numerals as those in FIG.

  The water supply tool 11 for planting has three levels of leveling layers 8a, 8b, 8c, and the innermost leveling layer 8a surrounds the capillary transport part 7 from the end of the guide tube 9 to the longest distance, The leveling layers 8a, 8b, 8c are stepped from the end of the guide tube 9 to different distances stepwise so that the uppermost leveling layer 8c surrounds the capillary transporting portion 7 from the end of the guide tube to the shortest distance. 7 is enclosed.

  With the above configuration, the capillary transport portion 7 is surrounded by the three leveling layers 8a, 8b, and 8c in the vicinity of the end of the guide tube 9, and has the greatest resistance to water leaching. In the portion near the tip of the capillary transport portion, the capillary transport portion 7 is surrounded by the two leveling layers 8a and 8b, and has a relatively small resistance to water leaching. Further, in the portion near the tip of the capillary transport portion, the capillary transport portion 7 is surrounded by one leveling layer 8a and has a relatively smaller resistance. At the tip of the capillary transport section 7, the capillary transport section 7 is in direct contact with the soil and has the smallest resistance to water leaching.

  According to this embodiment, the leaching of water is suppressed in the vicinity of the end of the guide tube 9, and the leaching of water becomes easier toward the tip of the guide tube 9. Water can be evenly leached from the entire end of the portion 7.

  The number of leveling layers is not limited to three and can be changed as appropriate. Further, the innermost leveling layer 8 a can surround the entire end portion including the end face of the capillary transport portion 7.

  FIG. 5 shows another embodiment of the water supply device for planting according to the present invention.

  The water supply tool for planting 12 shown in FIG. 5 has a leveling layer 13 whose thickness changes.

  In FIG. 5, except for the water supply tool for planting and the leveling layer, the same parts as in FIG.

  The water supply tool 12 for planting has one leveling layer 13, and the leveling layer 13 is formed at the end of the capillary transport portion 7 protruding from the end of the guide tube 9. There is a gradient in thickness so that it is thick at the proximal end and thin at the distal end of the same end.

  The tip of the capillary transport section 7 is directly buried in the soil and is in direct contact with the soil.

  In the present embodiment, the leveling layer 13 has a relatively large resistance to water leaching because it is thick at the proximal portion of the end of the guide tube 9 and is thin at the distal portion of the end of the guide tube 9. Therefore, it has a relatively small resistance to water leaching. At the proximal portion of the end of the guide tube 9, it is difficult for water to leach out, and at the distal portion, water is liable to leach out. Furthermore, since the capillary transport portion 7 is in direct contact with the soil at the distal end portion of the capillary transport portion 7 Can be leached easily. As a result, water is evenly leached into the soil from the entire end of the capillary transport section 7 from which the end of the guide tube 9 protrudes.

  In the present embodiment, the tip of the capillary transport part 7 is not covered with the leveling layer 13, but the tip of the capillary transport part 7 may be covered with the leveling layer 13. In the present embodiment, the leveling layer 13 is gradually reduced in thickness from the end of the guide tube 9, but the thickness may be reduced stepwise.

  According to the water supply device for planting of the present invention, an appropriate amount of water can be directly supplied to a place suitable for water absorption of plants. According to the present invention, water supply ideal for plants can be realized.

  FIG. 6 shows a comparison between the case where the water supply tool for planting of the present invention is used and the case where water is supplied from above the plant.

  FIG. 6 (a) shows a case where water is supplied from above the plant as in the prior art, and FIG. 6 (b) shows a case where the water supply tool for planting 1 of the present invention is used.

  The soil suitable for plant growth has a sparse structure in which the particles of the soil are in gentle contact with each other and contains abundant air inside. However, when water is poured into the planting plant 14 from above as in the case of FIG. 6A, the water flows below the pot 15 while washing fine particles in the soil. Further, water stays on the surface of the soil until it is absorbed, and forms a mud layer 16 that is clogged after drying. By repeating this, the soil in the pot 15 becomes clogged after a long period of time, and the mud layer 16 is also formed on the surface portion.

  As a result, the supply of oxygen to the soil is blocked by the mud layer 16, dense soil with poor ventilation is formed inside the pot 15, and supply of oxygen, nitrogen, etc. to the roots of the plant 14 for planting Is inhibited.

  In addition, the soil below the pot 15 contains fine particles, the drainage is poor, and a constantly moist soil area 17 is formed at the bottom of the pot 15, causing root decay of the plant.

  As described above, when water is repeatedly poured from above into the plant 14 for planting, the supply of oxygen and the like to the soil is hindered, and the possibility of causing root rot and the like increases.

  On the other hand, in the case of FIG. 6B in which water is supplied to the planting plant 14 using the planting water supply tool 1 of the present invention, the sparse soil containing abundant air inside is provided. Does not break the structure.

  That is, according to the water supply tool for planting 1 of the present invention, water gradually leaches into the soil by capillary action, so the flow rate of water is slow and fine particles of the soil do not flow. It won't clog the sparse structure of the soil.

  Moreover, the water supply by the water supply tool for planting of the present invention can leaches water only around the water supply tool for planting 1 as shown in FIG. 6 (b).

  Thereby, as shown in FIG.6 (b), the moist soil area | region 17 is formed in the front-end | tip of a plant root, On the other hand, the surface vicinity of soil can be made into the comparatively dry state. This state is close to the state where plants grow on the ground, and the soil can absorb water because the soil contains moisture at the tip of the root, while the root can absorb oxygen, nitrogen, etc. because the soil contains air near the ground surface, An extremely suitable environment for plant growth can be provided.

  According to the water supply tool for planting 1 of the present invention, water can be supplied only to a place suitable for water absorption of a plant, for example, the tip of the root, and an appropriate amount can be obtained by suppressing the amount of water leached by the leveling layer. Of water can be supplied. In addition, since the leaching of water is slow, highly permeable soil can be provided without breaking the sparse structure of the soil (the structure containing air inside).

  Thereby, according to the water supply tool 1 for planting of this invention, the water | moisture content required for a plant can be supplied, maintaining the state of the soil suitable for the growth of a plant for a long period of time.

  The water supply device for planting according to the present invention sucks water from a water source, transports water by a capillary transport section having a strong capillary force gradient, prevents water from leaching by a guide tube during transport of water, Then, it has the characteristic of leaching water uniformly from the whole edge part of the capillary conveyance part which protruded from the guide pipe | tube.

  However, there is a limit to the length of the end of the capillary transport section that allows water to be leached evenly.

  Therefore, FIG. 7 shows a water supply method for planting in which water is uniformly leached from the capillary transport section over a long distance to wet a large area of soil.

  In FIG. 7, reference numeral 18 indicates a plurality of plants to be supplied with water. On both sides of the plant 18, a plurality of planting water supply devices 1 of the present invention are arranged. The plurality of water supply devices 1 (end portions of the water supply device 1) are parallel to the soil, and the second end portion 7b of the capillary transport portion of each water supply device 1 partially overlaps in the length direction. Are arranged as follows. In addition, the 2nd end part 7b of the capillary transport part of each water supply tool 1 may be arrange | positioned continuously, without overlapping partially.

  By disposing the water supply tool 1 for planting as described above, the water leaches out from the second end 7b of each capillary transport section, wets the soil evenly over a long distance, and as shown in FIG. A wide range of uniform wet soil areas 19 can be formed.

  According to the water supply method for planting of this embodiment, water can be efficiently supplied to a wide area such as a field.

  The planting water supply tool 1 may be installed only on one side of the plant 18. Moreover, although not specifically shown in FIG. 7, you may make it install the several water supply tool 1 for planting in a planter etc. like FIG. 7 naturally. The number of water supply devices 1 for planting can be adjusted as appropriate.
