Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pot for cultivating and distributing plants, and more specifically, it can be widely used for general plants in general, but is a pot that is particularly suitable for the purpose of cultivating and distributing fruit trees and seedlings with deep roots.

[0002]

[Prior Art]

 Traditionally, pottery or plastic cylindrical flower pots or rectangular planters have been widely used for plant cultivation and distribution.

However, the pots of pottery are easily cracked, and in addition to those made of plastic, they are often cracked or broken.

The depth of soil in these pots and planters is usually the same as the diameter of flower pots or the short diameter of rectangular plants. Therefore, when cultivating a plant with deep roots, a very large flowerpot is required, which makes it heavy and inconvenient to handle.

Further, a large area is required for transportation with plants planted in these flower pots or planters or for display in a horticultural store, and it is also wide for transportation or storage of empty flower pots or planters. Problems such as the need for space have been pointed out in the past.

[0006]

[Problems to be solved by the device]

 In view of the above-mentioned problems, the present invention does not use a large-diameter flower pot, not only for cultivating general plants but also for cultivating fruit trees with deep roots. Therefore, it is an object of the present invention to provide a pot for cultivating and distributing plants, which is suitable for transportation and display in a horticultural store and has no risk of damage.

[0007]

[Means for Solving the Problems]

 As a result of various studies on the improvement of pots for cultivating and distributing plants with deep roots such as fruit tree seedlings, the present inventor has found that pots with a small diameter and a long shape grow rapidly because the amount of soil is large relative to the diameter. In addition, we also found the merit that the space required for transportation and display of garden shops can be reduced, and to prevent damage during storage, cultivation and distribution before use and to improve economic efficiency, use a pot with a plastic film or sheet. As a result of examining the making, the present invention was reached.

That is, a plastic film or sheet, a net, or a sheet obtained by combining these is wound into an elongated tubular shape, and the bottom portion is folded to provide a bottom surface, and portions having water draining and gas distribution functions are provided on the side surface and the bottom surface. In the structure provided, this is a pot for cultivation and distribution of plants in which the height of the pot is 1.5 times or more the diameter of the bottom surface or the length of the crossover. Here, the part having the function of draining water and air circulation consists of a large number of small holes formed in the film surface, or at least a part of the sheet is made of a material having gas permeability such as moisture and air, carbon dioxide gas. It is more preferable when used.

Here, the diameter of the bottom surface of the pot or the length of the crossover means the length of the longest crossover portion in the shape of the cross section of the cylindrical pot. For example, if the shape of the pot is cylindrical, it is the circular diameter of the bottom surface, if the cross section of the cylindrical pot is elliptical, it is the major axis of the ellipse, and if it is rectangular or rectangular, it is the diagonal length. is there. In addition to thick films, plastic sheets also include non-woven fabrics, woven fabrics, and knitted fabrics made of plastic fibers formed into sheets.

The present invention will be described in detail below.

In the present invention, the material of the pot needs to be a plastic film and / or sheet and / or net. For example, it may be a film or a sheet or a net only, and a part may be a film or a pot made of a sheet or a net. Alternatively, these may be laminated and used.

The type of plastic is not particularly limited as long as it can form a sheet, a non-woven fabric, a woven fabric or a knitted fabric using a film, a net or a plastic fiber as a raw material, and a wide range of plastics can be used. For example, as thermoplastics, for polyolefins, polyethylene resin, polypropylene resin, chlorinated polyethylene resin, chlorinated polypropylene resin, butadiene resin (Shinjo Tactic 1, 2 polybutadiene), 4 fluorinated ethylene resin, 4 fluorine Polyethylene-6-fluoropropylene resin, vinyl-based vinyl chloride resin, ethylene / vinyl chloride copolymer resin, ethylene / vinyl acetate copolymer resin, ethylene / vinyl alcohol copolymer resin, vinylidene chloride resin, chlorinated chloride Examples thereof include vinyl resin, vinylidene fluoride resin and polystyrene resin. Further, in the polyamide system, there are various types of nylon such as nylon 6 and nylon 66, copolymer nylon, and polyimide resin, and in the polyester system, there are polyethylene terephthalate resin, polybutylene terephthalate resin and the like.

Other thermoplastics include acrylonitrile / styrene resin (AS resin), acrylonitrile / acrylic styrene resin (AAS resin), acrylonitrile / butadiene / styrene resin (ABS resin), methylmethacrylate / butadiene / styrene resin ( MBS resin), ethylene / propylene / diene / styrene / acrylonitrile resin (EPSAN resin), methacrylic resin (PMMA), fluororesin, phenoxy resin, polyacetal resin, polycarbonate resin, polysulfone resin, polyphenylene oxide resin, ionomer resin, etc. Be done.

Further, in some cases, a thermosetting resin such as phenol resin, unsaturated polyester resin, or polyurethane resin can be used.

The film of these plastics is, for example, one having a permeability to air or carbon dioxide gas such as polyethylene resin or polypropylene resin, and one having a high moisture permeability such as ethylene / vinyl alcohol copolymer resin. Some films have unique properties. It is also possible to select the material depending on the application. Of these resins, polyethylene and polypropylene resins are the most preferred because of their physical properties, processability and economic efficiency.

Further, these plastics may be used alone or as a mixture of two or more kinds, and in the case of forming a non-woven fabric or the like from plastic fibers, plural kinds of fibers may be used. It may be mixed and molded from.

When a non-woven fabric is used as a pot, it usually has sufficient liquid permeability such as moisture and gas permeability of air or carbon dioxide gas. In addition, fibers made of plastic, that is, synthetic fibers, have recently been developed into ultrafine fibers of 0.001 denier or less, which is equivalent to about 1/100 to 1/1000 of the diameter of conventional thinnest fibers, and made from such ultrafine fibers. Some of the non-woven fabrics have a property of not allowing water droplets, which are liquids, to pass through, but allowing only gases such as water vapor, air, and carbon dioxide gas to pass through. Such a non-woven fabric can be used depending on the application.

It is necessary to provide a water drain and an air circulation port on the side and bottom of the pot of the present invention. For this reason, a large number of small holes may be formed on the film surface, but it is also possible to use a net or a nonwoven fabric having moisture and gas permeability in at least a part thereof.

A plastic film can be usually formed by an extrusion molding method, a net can be formed by an injection molding method, or can be formed by weaving filaments, and a non-woven fabric can be formed by felting synthetic fibers by a conventional method. The woven and knitted fabrics can be obtained by a usual method.

Next, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of the present invention. Reference numeral 1 denotes a main body of a pot, which is formed by winding a rectangular polyethylene film 2 having a black thickness of 0.2 mm and fixing it with a stapler 3 to form a cylindrical shape. Among the divided points, two symmetrical points are folded deeply into the inside8, then the remaining two points are folded into the inside of the cylinder in the same way, 8, the lower part of the cylinder is closed, and it is stopped with the stapler2. is there.

In FIG. 2, the contour of the bottom surface is a slightly distorted circular shape because the film is folded inward from the four corners of the circumference to form the bottom surface.

Several small holes 4 for draining water and circulating air are provided on the lower side surface and the bottom surface of the cylinder. Inside the cylinder, except for a small part at the top, soil 6 is put, and seedlings 7 are planted in it.

The cross section of the pot of the present invention is not limited to a circular shape, but may be an elliptical shape, a rectangular shape, a rectangular shape, or any other shape. The material of the pot is a plastic film or sheet or a net, or a combination thereof. For example, a part of the pot is a net and the other part is a film or a sheet. Since all of these are extremely flexible, they can be easily formed into any shape. Also, the pot is much lighter than conventional pottery or plastic flower pots and there is no risk of cracking.

The cross section is not limited to a constant size from the upper part to the lower part. The shape may be such that the upper part is large like the general flower pot, that is, the upper cross-section is large and the lower cross-section is small, or conversely, the lower cross-section is larger than the upper cross-section. Still another shape, for example, a shape in which the intermediate portion is swollen may be used.

The height of the pot shown in FIG. 1 is about twice the diameter of the cylinder. The ratio of the diameter to the height of the upper part of ordinary pottery or plastic flowerpots varies considerably, but most of them are almost the same, and even elongated ones generally have a height less than 1.5 times the diameter of the top surface. Many.

The ratio of the diameter to the height of the pot of the present invention should be 1.5 times or more. Therefore, it is characterized by a significantly elongated shape compared to commonly used flowerpots. Therefore, it is suitable for cultivating plants with deep roots, for example, fruit tree seedlings, tropical fruit seedlings, etc., as well as for their distribution and display in a garden store. The ratio of pot diameter to height is more preferably 1.8 to 2.5 times.

FIG. 3 shows another embodiment of the present invention, in which the pot has a rectangular cross section, the upper two-thirds of the pot is made of brown polypropylene film 2 having a thickness of 0.2 mm, and the lower portion is One third is a brown polypropylene net 9, which is molded by the heat-sealed portion 10. It is not necessary to provide the small holes as shown in FIG. 1 because the lower part and the bottom surface of the side surface are nets and the entire part has a drainage function and a gas distribution function.

Since the pot of the present embodiment has a rectangular cross section, it is suitable for planting a plurality of seedlings and the like.

The pot of the present invention needs to be provided with a portion having a drainage function and an air circulation function on the side surface and the bottom surface. However, this functional portion is not limited to the structure in which the small holes are provided on the side surface and the bottom surface as shown in FIG. 1, and may be a structure in which at least a part of the net is used as shown in FIG. 3, or Further, a structure using a non-woven fabric having water drainage and air circulation in at least a part may be used. Further, a structure in which these functional parts are used together, including the small holes, may be adopted.

The plastic film or sheet or the net used for the pot of the present invention may have any color. Generally, black or brown is often used, but a transparent film may be used. With the transparent film, the growth of roots inside the pot can be observed, and this can be used not only for academic research but also for increasing the commercial value in some cases.

FIG. 4 shows still another embodiment of the present invention, in which 1 is the body of the pot, and a rectangular polyester non-woven fabric 11 having a gray thickness of 0.3 mm is wrapped around it and fixed with a stapler 2 to form a cylindrical shape. As shown in FIG. 2, the bottom surface 5 is formed by closing the lower part of the cylinder and fixing it with a stapler 2. It is not necessary to provide small holes on the surface of the non-woven fabric, because the whole body is made of non-woven fabric having the functions of draining water and air circulation.

[0032]

[Action]

 Generally, a large circular opening is provided on the bottom surface and several large openings are provided on the bottom surface of the planter for draining water and air from the pottery or plastic flower pot. Even if the pot of the present invention is made only of a film having almost no air permeability, it is easy to make a large number of small holes for draining water and air on the side and bottom. Further, when the pot is made of a net or a sheet containing a breathable non-woven fabric, it plays the role of an opening having a low flow resistance of moisture and gas over a wider area.

When a plant is cultivated in a pot such as a flower pot, there are excess water at the time of irrigation, water vapor evaporated from soil, and carbon dioxide gas generated by respiration of roots as components discharged from the water drainage and air circulation ports, Oxygen gas required for root respiration is necessary for the components introduced into the interior, and the air that fills the pores of the soil aggregates increases or decreases the amount of water contained in the soil, It plays a role such as inhalation and exhaust along with the expansion and contraction of air due to temperature changes. Since these effects are not sufficient with only the surface of the soil above the pot, an opening is provided in the bottom of the flowerpot, etc.The pot of the present invention has the area of the opening and the flow resistance of the conventional flowerpot. It is far superior to the others.

The pot of the present invention can be used for cultivating almost all plants, but since it has an elongated shape, it is also suitable for cultivating seedlings of fruit trees with deep roots. A plant with deep roots requires a fairly large pot in an ordinary plant pot, but the pot of the present invention can be cultivated if it is made a little longer, without making the diameter too large. Therefore, it is suitable for cultivating tropical fruit saplings such as persimmon, mango, and guava, which have deep roots among fruit trees, and also suitable for peony, peony, stone Kusu, cherry trees, and other saplings. The fact that it can be cultivated with deep roots is the same as that planted in fields or alleys, and it is close to nature and is preferable for cultivation.

Since the shape of the pot is long and slender, the amount of soil is large irrespective of the diameter, and the amount of soil in the pot with a diameter of 12 cm of the present invention is almost the same as that of the plastic flower pot with a diameter of 18 to 27 cm. Therefore, the pot of the present invention having the same diameter has better plant growth than the plastic flower pot, and as a result of a comparative test under the same cultivation conditions with peach, persimmon, and apple seedlings, the diameter of the present invention was 12 cm. The growth condition of the pot was the same as that of a commercially available plastic flower pot with a diameter of 24 cm, and almost no growth occurred when a commercially available plastic flower pot with a diameter of 12 cm was used.

Since the pot of the present invention has a small diameter in spite of the amount of soil, it is suitable for transportation and display in a garden store, and can be folded and stacked before use, which is convenient for transportation and storage, and economical. It is highly likely.

[0037]

[Effect of the device]

 By using the pot of the present invention, a large number of plants can be cultivated even in a narrow space, and it is particularly suitable for cultivating seedlings of fruit trees with deep roots. In addition, compared to ordinary pottery or plastic flower pots, the amount of soil is large compared to the diameter, and the water drainage and gas distribution functions are excellent, and plant growth is good.

Further, since the diameter of the pot is small, it is suitable for cultivation, transportation and display in a horticultural store, and it can be folded and transported before use so that it can be transported and stored, which requires less space and is highly economical.
