Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a seedling raising tray suitable for use in pot cultivation of plant seedlings such as flowers and vegetables.
[0002]
[Prior art]
A conventional tray for raising seedlings is disclosed in, for example, Japanese Utility Model Publication No. 4-27314. This type of tray has a plurality of storage portions into which soft pots for raising seedlings are inserted, and facilitates handling of the seedlings.
[0003]
On the other hand, Japanese Patent Application Laid-Open No. 7-31288 discloses a storage portion comprising a bottom plate, a leg plate raised at the peripheral end portion of the bottom plate, and a frame plate fixed to the upper end of the leg plate in the vertical direction and the horizontal direction. A horticultural tray provided continuously in a direction, which has a structural feature when a notch groove is formed in an upper end portion of a frame, is disclosed.
[0004]
[Problems to be solved by the invention]
However, for example, according to the seedling raising tray disclosed in Japanese Utility Model Publication No. 4-27314, etc., when moving seedlings from the tray to other places, the pots are picked and taken out one by one from the storage unit, There was a problem that it was time consuming and cumbersome and its work efficiency was extremely poor.
[0005]
On the other hand, according to the seedling raising tray 20 disclosed in Japanese Patent Laid-Open No. 7-31288, as shown in FIG. 6, the lower end portion of the frame plate 21 is formed in the horizontal direction, and this lower end portion is filled with soil. It bites into the peripheral wall 22 of the soft pot, thereby suppressing the vertical movement of the pot. In addition to this, the soil in the pot has been lowered due to irrigation during raising seedlings, and the soil has been tightly tightened. Furthermore, the surface of the leg and the outer surface of the peripheral wall 22 of the pot are in contact with each other over a wide range. Since the dynamic resistance is large, it is difficult to simply pull the top end of the pot, and sometimes there is a problem that a complicated work of removing the attached leg and the pot is required.
[0006]
In addition, according to these conventional trays for raising seedlings, for example, water that has sprinkled between the legs and the pot may accumulate due to capillarity, and mold or the like may grow. There is also a problem that it is easy to cause a phenomenon called a looping phenomenon.
[0007]
The present invention has been devised in view of such circumstances, and the problem to be solved is to solve the above-mentioned problems and problems of conventional seedling raising trays, and the purpose thereof is The purpose of the present invention is to provide a cell tray for raising seedlings that has a simple structure and can easily take out a plurality of soft pots without damaging plants.
[0008]
[Means for Solving the Problems]
The gist of the means adopted by the present invention to solve the above problems is as described in the appended claims.
[0009]
According to the seedling raising tray of the present invention adopting such a configuration, when a soft pot is placed in the storage portion, each soft pot can be supported and held by a substantially Y-shaped side frame, and the upper end of each pot. A plurality of pots can be taken out simultaneously by overlapping the upper end portions of the pots adjacent to each other. Moreover, since the lower end part of the side frame is formed not in the horizontal direction but in an oblique direction, it is difficult for the lower end part to bite into the peripheral wall of the soft pot filled with soil. Therefore, even if the soil in the pot is lowered due to irrigation or the like and the soil is tightly tightened, it can be easily extracted simply by picking up the upper end of the pot.
[0010]
Next, the drainage hole opened at the lower end of the side frame can prevent, for example, water that has been sprinkled, for example, between the legs and the pot. Therefore, generation | occurrence | production of the mold etc. in this position is prevented.
[0011]
In particular, according to the seedling raising tray adopting the configuration as claimed in claim 2, in addition to the above-described action, the side frame is provided with a vertical protrusion that protrudes inward of the storage portion. Therefore, the outer peripheral wall of the soft pot can be placed in a state of partially floating from the surface of the side frame, and the sliding resistance when the pot is pulled out can be suppressed, and the air movement between the two in the vertical direction can be prevented. A gap that can be formed can be formed, and the central portion of the seedling tray can be prevented from becoming an excessively humid atmosphere.
[0012]
In addition, the protruding line walls in the vertical direction can be formed in the soft pot by each protrusion, the internal volume of the pot can be reduced, and the amount of cultivated soil that can be stuffed can be saved. Further, when the root grows and extends in the circumferential direction along the inner surface of the pot, the root growth point abuts on the ridge line wall and extends downward without extending further in the lateral direction. Therefore, the root winding phenomenon is prevented.
[0013]
The plurality of protrusions provided with the side frames improve the strength of the tray.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described in more detail based on more specific examples shown in the drawings. However, the present invention is not limited to the following examples unless it exceeds the gist of the present invention.
[0015]
By the way, although it does not restrict | limit especially the soft pot 30 applied to the tray 10 for raising seedlings of this invention, as shown in FIG. 7, the cylindrical surrounding wall 31 which terminates in an opening edge in the upper end side, and the surrounding wall 31 If the bottom wall 32 continues to the lower end side in the axial direction, and four corner holes 33 are formed in a cross shape at the corners of the peripheral wall 31 and the bottom wall 32, for example, moderate water retention It is extremely suitable because the property and water permeability can be secured more effectively. However, the size and shape of the seedling tray is a matter that is appropriately changed in design based on the size and shape of the soft pot to be applied, and the cross-sectional shape of the soft pot is rectangular to circular or other shapes. It doesn't matter.
[0016]
In addition, the material for producing the seedling tray 10 of the present invention is not particularly limited, but from the viewpoint of ease of molding and cost, polystyrene (PS), polyethylene (PE), polypropylene (PP), A synthetic resin such as ABS is preferable, and a biodegradable material is preferable from the viewpoint of preventing environmental pollution.
[0017]
1 is a partial plan view schematically showing a seedling tray 10 according to the first embodiment of the present invention, FIG. 2 is a partial side view of the seedling tray 10, and FIG. 3 is a partial side view of the seedling tray 10. FIG. 4 is a partial longitudinal sectional view taken along line AA of FIG.
[0018]
In the figure, the seedling tray 10 includes a bottomed storage portion 13 formed by a bottom plate 11 and four substantially Y-shaped side frames 12 rising from the outer peripheral edge of the bottom plate 11 in a vertical direction. A large number of soft pots 30 for raising plant seedlings such as flowers and vegetables can be inserted into each of the storage portions and supported by each.
[0019]
The side frame 12 is integrally formed in a substantially Y shape having a drain hole 14 at the lower end thereof, and the upper end surface is not formed with any cutout groove having a surface connected to the upper end surface. The side frame 12 is arranged in a state of being inclined along the inclination of the peripheral wall 31 of the soft pot 30, and the lower end portion 11 a is connected and fixed to the outer peripheral edge portion of the bottom plate 11. The height of the side frame 12 is approximately the same as the height of the soft pot 30, and the lateral width is approximately the same as the diameter of the upper end opening of the soft pot 30.
[0020]
The diameter of the bottom plate 11 is formed to be slightly larger than the diameter of the bottom surface of the soft pot 30.
[0021]
According to the seedling tray 10 adopting such a configuration, soil is put in each pot and seeded or seedlings are planted, and if necessary, the fertilizer is applied and the seedlings are sprinkled as needed, and then the lower end of the side frame 12 Since the drain hole 14 is opened, moderate drainage and moderate water retention can be maintained. In addition, the function as a ventilation hole can be expressed to maintain the optimum air permeability and promote the development of roots, and water does not accumulate at this position and mold or the like does not occur.
That is, it is possible to obtain an operational effect that watering work, water retention management, and aeration management can be performed very simply and efficiently, and an optimal growth environment of the plant can be maintained.
[0022]
On the other hand, when a long ridge 15 is formed on the surface of the side frame 12 on the side of the storage unit 13 and protrudes in the up and down direction of the storage unit 13, the soft pot 30 attached to the storage unit 13 The peripheral wall 31 is pressed by these protrusions 15 and can be dented inward, whereby a convex line wall can be formed inside the soft pot 30. For this reason, it is possible to reduce the amount of soil used for soiling.
[0023]
When the root grows and extends in the circumferential direction along the inner surface of the pot, the root growth point abuts on the ridge line wall and extends downward without extending further in the lateral direction. Therefore, the excellent effect that the root winding phenomenon can be prevented and seedlings excellent in growth after being cultivated can be grown is also obtained.
[0024]
Further, as shown in FIG. 5, the outer peripheral wall 31 of the soft pot 30 can be arranged in a state of being partially lifted from the surface of the side frame 12, that is, the side wall 15 a of each protrusion 15 and the peripheral wall 31 of the soft pot 30. The two gaps 16 that allow the air movement in the vertical direction can be formed between them, and the sliding resistance when the pot 30 is extracted can be suppressed. For this reason, when performing so-called transplantation in which seedlings are extracted from each soft pot and replanted, or so-called potting work in which the extracted seedlings are replanted into a larger pot, sliding resistance when extracting the pot is suppressed. The effect of being able to pick up the upper ends of adjacent pots by hand and take them out at the same time is obtained.
[0025]
Furthermore, it is possible to prevent high humidity in the seedling tray, particularly in the vicinity of the center.
[0026]
By the way, the height of the protrusion 15 (the height of the rising wall) is preferably 0.3 to 4 mm. If it is less than 0.3 mm, the effect of preventing root winding and the ventilation effect are poor, and if it exceeds 4 mm, it is difficult to overlap the pots. In addition, when the protrusion is rounded, the effect of preventing root winding and the ventilation effect are poor. The width of the ridge (the width of the top wall) is also preferably 0.3 to 4 mm.
[0027]
The height and width of the ridges 15 do not have to be the same over the entire length, and the dimensions may be different on the way as long as there is no problem with die cutting or the like. 10 is preferable because it is convenient for superposition of ten. Further, the protrusion 15 is preferably provided from the vicinity of the upper end of the side frame 12 to the vicinity of the lower end. In addition, although it does not limit the quantity, arrangement | positioning position, etc. of the protrusion provided in the side frame 12, it is preferable that it is 4-12, and it is preferable to distribute as evenly as possible in the circumferential direction of the accommodating part 13. FIG. .
[0028]
It is preferable that both the side frames 12 and the corners of the protrusions 15 are formed in a round shape. This is because the die removal during molding can be performed smoothly and the sliding resistance when the pot is extracted can be lowered.
[0029]
The present invention is not limited to the seedling raising tray described in the above examples, and can be implemented with appropriate design changes without departing from the spirit of the present invention.
[0030]
【The invention's effect】
As described above, the seedling raising tray of the present invention has a very simple structure and can be manufactured very easily by a plastic molding technique, and can be overlapped with pots in terms of suitability for mass production. Therefore, it can be said to be extremely advantageous economically in that it does not become bulky during storage and transportation.
[0031]
Furthermore, the seedling raising tray of the present invention is
(1) The point that each soft pot can be supported and held by a substantially Y-shaped side frame, and the upper end of each pot can be stably supported
(2) Even if the soil in the pot is lowered due to irrigation etc. and the soil is tightly tightened, the tops of the adjacent pots can be overlapped and a plurality of pots can be taken out simultaneously,
(3) A drainage hole is formed at the lower end of the side frame, and in particular, for example, water sprayed, for example, can be prevented from accumulating between the leg and the pot, and generation of mold or the like at this position can be prevented. In other words, watering work, water retention management, and aeration management can be performed very easily and efficiently to maintain an optimal growth environment for plants,
(4) Since the side frame is provided with protrusions that protrude inward of the storage part, the outer peripheral wall of the soft pot can be placed partially floating from the surface of the side frame, and the pot is removed. The point that can reduce the sliding resistance when
(5) Between the side frame surface and the outer peripheral wall of the soft pot, it is possible to form a gap that allows air movement in the vertical direction, and in particular, it is possible to prevent an excessively humid atmosphere near the center,
(6) Each ridge can form a vertical line wall in the soft pot, reducing the internal volume of the pot, saving the amount of soil that can be stuffed, and growing the roots. When extending in the circumferential direction along the inner surface of the pot, the root growth point abuts on the ridge line wall and extends downward without extending further in the lateral direction. Therefore, it is possible to cultivate seedlings that can prevent the root winding phenomenon and have excellent growth after survival,
Is extremely effective.
[0032]
It also has sufficient strength during storage, transportation and seedling raising.
