For this reason, the fall of the water supply capability of a water supply string can be prevented, and there exists an effect that water can be supplied stably over a long period of time.

An embodiment according to the present invention will be described with reference to the accompanying drawings of FIGS.
In the first embodiment, as shown in FIGS. 1 to 4, the cultivation container 10 having a substantially flat plane, the automatic water feeder 20 installed on the bottom surface of the cultivation container, and the burying material for embedding the automatic water feeder 20 are used. 30, a water supply string 31 that is drawn from the automatic water feeder 20 and arranged along the inner surface of the cultivation container 10, a water supply material 32 that covers the water supply string 31 while being in contact with the water supply string 31, and the automatic It consists of a partition paper 33 for covering the water supply device 20, the buried material 30, and the water supply material 32 and partitioning it from the cultivated soil 34.

  The cultivation container 10 has a substantially rectangular quadrangular pyramid shape and has a corner chamfered.

  As shown in FIGS. 2 and 4, the automatic water feeder 20 is disposed on the water supply body 23 having a water storage space 23 a in which the water injection port 21 is sealed with a sealing plug 22, and the bottom surface of the water supply body 23. And a water level adjuster 24 (see FIG. 4). The water level adjuster 24 has a water supply string insertion tube portion 25 installed on the ceiling surface thereof protruding from the ceiling surface of the water supply body 23, and a vent hole 26 provided on the upper side wall of the water level adjuster 24 via a vent pipe 27. And communicate with the outside air. Further, the water level adjusting chamber 24 a in the water level adjusting tool 24 communicates with the water storage space 23 a through a water supply hole 28 provided in the vicinity of the bottom surface, and between the water supply hole 28 and the vent hole 26. The water storage space 23a communicates with the air supply hole 29 provided.

  Therefore, as shown in FIG. 4A, when the water 36 in the water storage space 23a is filled up to a predetermined height in the water level adjusting chamber 23a, the automatic water feeder 20 has a capillarity phenomenon. The water sucked up by one end is supplied to the cultivated soil 34 via the water supply material 32 and the partition paper 33.

  As shown in FIG. 4B, when the water level in the water level adjusting chamber 24a becomes lower than the air supply hole 29, the outside air that has entered through the vent pipe 27 leaks from the air supply hole 29 into the water storage space 23a. For this reason, the balance of air pressure between the water storage space 23a and the water level adjustment chamber 24a is lost, and the water in the water storage space 23a enters the water level adjustment chamber 24a through the water supply hole 28, and the water level in the water level adjustment chamber 24a is reduced. The air supply hole 29 is pushed up and closed. Thereafter, the water 36 is stably supplied to the water supply string 31 by repeating the same operation. The water 36 is not limited to pure water but may be liquid fertilizer.

  The embedding material 30 is for embedding the automatic water feeder 20 for laying the partition paper 33 to be described later, and preferably has a heat insulating effect and can prevent the generation of slugs and the root of the plant 36. Examples thereof include rice husk, perlite, sawdust, and Kanuma soil.

  The water supply string 31 is for sucking up water 36 from the water supply body 23 by a capillary phenomenon and supplying it to the cultivated soil 34. For example, a bundle of fibers, or a rope formed by twisting a belt-shaped synthetic fiber sheet.

  As the strip-like synthetic fiber sheet, for example, 1.2 to 3.0 denier, preferably 1.2 denier acrylic fiber is put into water, and a slurry obtained by stirring is formed, and a table of the obtained wet sheet is obtained. The back surface is subjected to a spanless method in which the water pressure is 5 to 15 MPa (megapascal), preferably 3 to 10 MPa. Thereby, a fine crack is generated in the acrylic fiber, and a strip-shaped synthetic fiber sheet is obtained in which the front and back surfaces are 0.1 to 1.2 denier, preferably a minimum of 0.1 denier acrylic segmented fiber.

  Further, as another belt-like synthetic fiber sheet, a slurry made of polyester composite fiber having a concentric cross section of 1.2 to 3.0 denier is made to obtain a wet sheet as an intermediate layer. On the other hand, a wet sheet that becomes front and back layers is obtained by making a slurry containing only acrylic fibers. Next, the wet sheet is laminated to obtain a laminated sheet having a three-layer structure, and then the acrylic fiber on the front and back surfaces is subjected to a spanless method in which the water pressure is 5 to 15 MPa (megapascal), preferably 3 to 10 MPa. . Thereby, a fine crack is generated in the acrylic fiber, and a belt-shaped synthetic fiber sheet is obtained in which the front and back surfaces are 0.1 to 1.2 denier, preferably 0.1 denier minimum.

  In the above-described embodiment, the single-layer or three-layer belt-like synthetic fiber sheet has been described. However, it is needless to say that the two-layer belt-like synthetic fiber sheet in which acrylic divided fibers are arranged on at least one surface may be used. is there.

  The water supply material 32 spreads the water sucked up by the water supply string 31 widely and uniformly, and supplies the water to the cultivated soil 34 widely and uniformly through a partition paper 33 described later. For this reason, the water supply material 32 according to the present invention may be a porous so-called sponge, and the porosity and thickness can be appropriately selected as necessary.

  When the water supply material 32 is a non-woven fabric, for example, it may be a single-layer or two-layer non-woven fabric made of a single acrylic fiber, and rayon and polyester fibers between the non-woven fabric made of a single acrylic fiber. It may have a three-layer structure in which a nonwoven fabric made of is laminated as an intermediate layer. In any case, the acrylic fiber located on the front and back surfaces is struck with a water jet of 5 to 15 MPa (megapascal), preferably 3 to 10 MPa, to cause fine cracks in the acrylic fiber, and 0.1 It is preferable to use acrylic divided fibers divided into denier (3-3.5 μ) to 1.2 (10-12 μ). This is because if it is less than 0.1 denier, it becomes difficult to form a nonwoven fabric, and if it exceeds 1.2 denier, the desired capillary phenomenon cannot be ensured.

  The reason why the rayon is added to the middle layer is to enhance the water supply function, and the reason why the polyester is added to the middle layer is that the fibers are bonded and integrated to ensure a predetermined strength. The reason why the acrylic divided fibers are arranged in the front and back layers is to enhance the capillary phenomenon and to prevent corrosion by covering the rayon added to the middle layer.

  The partition paper 33 is used to prevent the roots of the plant from advancing and getting entangled with the water supply string 31 and to supply the cultivated soil 34 with a wide diffusion of the water supplied by the water supply string 31. For this reason, it is necessary for the partition paper 33 not to corrode even if it is embedded in the cultivated soil 34, and for example, Sanmore (product number 1445) manufactured by Sanwa Paper Co., Ltd. can be used.

  The sun moor made a slurry of 1.5 denier concentric ES fibers (manufactured by Chisso Corporation) with polypropylene at the center and polyethylene with a melting point of 130 degrees on the surface, and the resulting wet sheet was heated. , By drying, the polyethylene is melted to integrate the fibers.

The partition paper 33 may be formed of one type of synthetic fiber instead of the composite fiber as described above. Examples of synthetic fibers include vinylon, acrylic, polyester, polyethylene, and polypropylene. When forming a partition sheet of synthetic fibers, basis weight 30~130g / ^{m 2,} in particular, is preferably 40 g / ^{m 2} or more. If it is less than a basis weight 30 g / m ^2, it can not be prevented expansion of plant roots. Further, if the basis weight exceeds 130 g / m ² , the papermaking operation becomes difficult.

  The water supply material 32 and the partition paper 33 may be used separately, but may be integrated in advance continuously or discontinuously by ultrasonic welding, stapler, adhesive, or the like. And if the water supply string 31 is inserted in advance between the water supply material 32 and the partition paper 33, there is an advantage that the number of work man-hours at the site can be reduced.

  The cultivated soil 34 is not particularly limited, and may be widely marketed.

  As shown in FIG. 5 to FIG. 7, the second embodiment is a cultivation container 10 having a substantially flat plane that is marketed as a so-called planter, an automatic water feeder 20 installed on the bottom surface of the cultivation container 10, and this automatic An embedded material 30 for burying the water supply device 20, a water supply string 31 drawn from the automatic water supply device 20 and arranged along the inner surface of the cultivation container 10, and a water supply material 32 for covering the water supply string 31, The automatic feeder 20, the buried material 30, the water supply string 31, and the water supply material 32, and the partition paper 33 for partitioning from the cultivated soil 34. The present embodiment is substantially the same as the first embodiment described above, and the same parts will be described with the same numbers.

The water supply string 31 may be arranged not only along the inner surface of the cultivation container 10 but also at the center of the cultivation container 10 and covered with the water supply material 32 and the partition paper 33.
Moreover, according to above-mentioned embodiment, there exists an advantage that the moisture content can be adjusted according to the state of a cultivated plant by taking out the embedded water supply string 31 and partially coat | covering with a water-impermeable sheet.

As shown in FIGS. 8 to 10, the third embodiment is a case where water is supplied from three automatic water feeders 20 to three cultivation containers via three relay water supply devices 40.
The automatic water dispenser 20 has a water storage space 23 a whose water inlet is sealed so as to be opened and closed with a sealing plug 22, and has a vertically long rectangular parallelepiped shape, and a vicinity of the bottom surface of the water feeder main body 23. And a water level adjuster 24 (see FIG. 9B) installed on the side wall.

  The water supply cylinder 41 communicating with the water level adjuster 24 protrudes from the side wall near the bottom surface of the water supply body 23. The water level adjuster 24 is connected to the ceiling surface and communicates with the outside air through a ventilation pipe 27 protruding from the ceiling surface of the water supply body 23. Further, the water level adjusting chamber 24 a in the water level adjusting tool 24 communicates with the water storage space 23 a through a water supply hole 28 provided in the vicinity of the bottom surface, and between the water supply hole 28 and the vent hole 26. The water storage space 23a communicates with the air supply hole 29 provided.

  As shown in FIG. 8, the water supply cylinder portion 41 is connected to a three-way branch valve 43 that branches in three directions via a water supply pipe 42 communicating therewith. The three-way branch valve 43 communicates with the relay water supply 40 via three water supply pipes 44. Furthermore, the water supply string 31 having one end inserted into the relay water supply device 40 is inserted into the flexible vinyl pipe 45 and drawn into the cultivation container 10. The flexible vinyl pipe 45 is for preventing water leakage and evaporation.

  As shown in FIG. 10, the cultivation container 10 is disposed along the inner surface of the cultivation container 10 with one end inserted into the buried material 30 spread on the bottom surface and the relay water supply device 40. The water supply string 31, the water supply material 32 that covers the water supply string 31 while being in contact with the water supply string 31, and the partition paper 33 that covers the embedded material 30 and the water supply material 32 and separates it from the cultivated soil 34. ing. Then, the cultivated plant 35 is planted and used in the cultivated soil 34. In the present embodiment, the burying material 30 may be used as necessary, and is not necessarily used. The other parts are almost the same as those of the above-described embodiment, and the same parts are denoted by the same reference numerals and the description thereof is omitted.

And while inserting a water supply string between the said water supply material and partition paper, the cultivation soil was filled with the said water supply material along the one side inner surface of the cultivation container disclosed by 2nd Embodiment. Furthermore, water was poured into the water supply body to make it full.

  The water supply material is composed of 2.2 denier concentric composite fibers (made by Teijin), whose center layer is made of polyester with a melting point of 230 and whose surface layer is made of polyester with a melting point of 120 degrees, and 1.7 denier rayon is put into water. , Stirring to obtain a slurry, and the resulting slurry was made into a wet sheet as an intermediate layer. On the other hand, 1.2 denier acrylic fiber was put into water and stirred to obtain a slurry, and the resulting slurry was made into paper to obtain two wet sheets to be front and back layers. And the wet lubrication sheet used as the front and back layers was laminated | stacked on the front and back of the wet sheet used as an intermediate | middle layer, and the lamination sheet was obtained. Subsequently, the laminated sheet was subjected to a spanless method of hitting with a water jet having a water pressure of 8 to 9 MPA (megapascal), and fine cracks were formed in the acrylic fibers located on the front and back surfaces to obtain acrylic split fibers. Further, the laminated sheet was heated and dried, and a polyester having a melting point of 120 degrees added to the middle layer was melted and integrated to obtain a sample. Therefore, a water supply material having a final composition of 15% by weight of polyester composite fiber, 20% by weight of rayon, and 65% by weight of acrylic fiber was obtained. The characteristics of the water supply material were measured. The measurement results are shown in FIG.

  The partition paper is a composite fiber having a concentric cross section made of polypropylene (50% by weight) in the center layer and polyethylene (50% by weight) having a melting point of 130 degrees, and an ES fiber having an average length of 15 mm and 1.5 denier. (Chisso Co., Ltd.) was added to water and stirred to obtain a slurry. And the wet sheet | seat obtained by continuously making the said slurry was heated and dried, and the polyethylene of the surface layer was melt-integrated and the sample was obtained.

And while making a water supply material go along the one side inner surface of a cultivation container, it filled with cultivation soil. Others were processed in the same manner as in Example 1 described above.

  A total of seven cultivation containers according to Examples 1, 2, and 3 were installed in a vinyl greenhouse. Then, after about one month, the cultivation soil was touched with a finger and the water supply condition was observed. As a result, it was confirmed that there was no water supply shortage, partial spot water supply, excessive water supply, and there was moderately uniform moisture. For this reason, 7 types of cultivation containers were seeded with corn, tomato, cucumber, eggplant, aster, carnation and sunflower seeds one by one, and the growth situation after about one month was observed. Despite not supplying water at all, there was no water shortage, partial spot water supply, root rot due to excessive water supply, overhumidity, etc., and corn etc. germinated and confirmed that their seedlings were growing . In particular, it was confirmed that corn was germinated at a higher germination rate than the usual cultivation method.

  In addition, in six new cultivation containers prepared in the same manner as in Examples 1, 2, and 3, each of the three sunflower seedlings that require a large amount of water for growth was replanted, about one month later. When we examined the growth situation, we were able to confirm that it was growing smoothly.
