Description

Planting container for seedlings {POT FOR GROWING OF SEEDLINGS}

The present invention relates to a cultivation container for seedlings, and more specifically, it is simple and simple to manufacture the structure, excellent physical strength and shape retention, while maintaining the air permeability and water retention properly, The present invention relates to a seedling cultivation container which is directed downward along the inner surface of the side wall and subsequently guided in the radial direction along the bottom surface to prevent looping.

Background Art Conventionally, when growing vegetable seedlings or flower seedlings, a growing container for seedlings having been molded into a pot shape made of soft plastic such as polyethylene or polypropylene has been used. Conventional seedling cultivation containers are commercially available as tray-type seedling pots by connecting a plurality of single seedling pot containers and a single seedling container. These conventional seedling cultivation containers have a port portion continuous to the cylindrical side wall and the lower end side in the axial direction of the side wall, and have a bottom surface having a drainage hole at the center thereof, so as to form a suitable cross-sectional seedling soil storage chamber. It consisted only of things.

When cultivating a plant using a plastic cultivation container, it is known to provide drainage and aeration holes in the perimeter wall as well as the bottom surface because it is very important to ensure the most appropriate breathability and drainage. It is also known to provide a long hole formed in a slit shape.

However, since conventional molds are molded by blow molding or vacuum molding of thin sheet materials, the thickness of the joints between the side walls and the bottom surface is extremely thin, so that the physical strength of the entire body is insufficient or the formation of the mold is difficult. There was a problem such as bad.

On the other hand, it is important to maintain the most appropriate breathability and water retention in order to grow seedlings with good lubrication and good growth. Since conventional synthetic resin seedling pots have very poor air permeability, it is proposed that a plurality of holes or slit holes are formed in the peripheral wall or the bottom surface where the air permeability of the cultured soil should be secured, and each hole is formed at the junction of the side wall and the bottom surface. However, since the conventional port adopting such a configuration forms these holes and slit holes by secondary processing after the mold is molded, this operation is very complicated and causes a cost increase. Also, if a plurality of holes or slit holes are provided in the side wall or the bottom surface, it is effective as a means of eliminating the so-called roofing phenomenon of the roots.However, even if the holes are made small or the width of the slit holes is narrowed, the culture soil will flow out. Since there are many parts, the loss of expensive culture soil is considerable, and when these accumulate, it becomes the amount which cannot be ignored, and the problem that the powder quantity becomes small becomes remarkable.

In addition, since some of the supplied water is likely to stay at the junction between the bottom and the bottom of the circumferential wall, it causes root corrosion and at the same time, the growth point of the root is deformed by the dwelling water and spirals downward along the circumferential wall without rooting. It elongates into a shape, the inside of which becomes cavitation (so-called looping phenomenon), impedes the formation of absorbent muscles, and adversely affects the lubrication after fixation. That required cutting the roots.

It is known that the above-mentioned flaws are provided with ribs of the upper and lower terms only on the sidewalls, and the ribs of the radiation are formed on the bottom surface so as not to be continuous with the drainage holes.

The present invention has been made in view of the above circumstances, and is intended to solve the above-mentioned shortcomings and problems seen in the conventional cultivation container. The structure is simple and the price can be manufactured at low cost, the physical strength and shape retention are excellent, the breathability and water retention can be properly maintained, and the side roots can be guided downward in the in-diameter direction. It is an object of the present invention to provide a seedling cultivation container that enables ideal seedlings to grow to a deeper layer because of good growth after rooting and good growth of roots.

(Designated embodiment)

An embodiment of the present invention will be described in more detail based on a more specific example shown in the drawings, which represents a representative one, and the present invention is not limited to the following examples unless departing from the gist thereof.

In addition, the material used to manufacture the seedling cultivation container of the present invention is not particularly limited, but synthetic resins such as polystyrene (PS), polyethylene (PE), and polypropylene (PP) may be used in view of ease of molding and cost. It is preferable that it is and it is preferable that it is a biodegradable material containing natural fiber from a viewpoint of environmental pollution prevention.

The seedling cultivation container 10 of the first embodiment is formed by molding a frame of a single pollen body with a blow molding method of polyethylene resin, and secondly processing the drainage hole 2 in the center of the bottom surface 1.

Figure 1 is a perspective view of the cultivation container 10 from the bottom to the top, Figure 2 is a cross-sectional view along the line CC of Figure 1, Figure 3 is a longitudinal cross-sectional view along the line AA of Figure 1, Figure 4 It is a longitudinal cross-sectional view along the BB line.

In the drawing, the cultivation container 10 is enlarged in diameter toward a bottom surface 1 having a drainage hole 2 in the center and upwards continuously up from the circumferential edge of the bottom surface 1. Four ribs A 7 and nine ribs B 9 which are formed in a single pollen shape by the inclined side walls 3 which are inflated inwardly with respect to the side walls 3 and the bottom surface 2. ) Is formed. The rib A 7 and the rib B 9 both extend radially from the center of the bottom surface 1 and extend continuously through the corner portions 4 to the top of the inclined side wall 3, and the inclined side wall The connection part 5 of the lower end of 3 and the bottom surface 1 is arrange | positioned rather than the inclined side wall 3 and the bottom surface 1 inward direction. In addition, the rib A (7) is located in the vicinity of the rib B (9) is one end is not continuous to the drain hole (2), whereas the one end is continuous to the drain hole (2). Differ from

The size of the cultivation container 10 and its cross-sectional shape are not limited, but may be rectangular to circular or other shapes, and the size width, quantity, and the like of the rib A 7 and the rib B 9 may be different. The design changes appropriately based on the size and shape of the cultivation container.

In addition, if the boss portion (not shown) protruding downward in the rib portion of the bottom surface is filled with culture soil, the bottom surface can be pushed downward with the weight of the culture soil to prevent the drainage hole 2 from closing. . That is, it is very preferable because the aeration and drainage effect can be enhanced and the strength of the rib can be supplemented.

According to the cultivation container 10 of the embodiment configured as described above, the following operational effects can be obtained.

First, since the rib of the side wall 3 and the rib of the bottom surface 1 are continuous in the junction part 5, even if this cultivation container 10 is shape | molded by the film processing method, it is the same as that of the conventional cultivation container. As in the case where this part is discontinuous, the pulling force acts more strongly where the thickness of each part becomes thinner, so that cracks and pinholes do not occur, so that formability and yield are remarkably improved.

In addition, the strength of the side wall itself can be increased by the rib of the side wall 3, and the strength of the bottom surface itself can be increased by the rib of the bottom surface 1, respectively. In addition, since the ribs of the connecting portion 5 are melted and solidified at the time of molding, they are formed into a band-like lump in a radial direction and are formed as discontinuous ring-shaped horizontal ribs, so that the side wall 3 and the bottom surface 1 The intensity | strength rise of the corner | angular part 4 of () is aimed at. And, thanks to this action, the shape retention and strength of the entire cultivation container 10 is improved.

In addition, since only one drain hole 2 is formed in the center of the bottom surface 1 (because there are not a plurality of holes or slit holes in the side wall 3 or the bottom surface 1), The runoff is low, and thus, expensive culture soil can be used without waste, thereby increasing the root volume.

In addition, the ribs of the bottom surface 1 are continuously formed in the drainage hole 2, so that the roots are difficult to corrode, especially since the supplied water hardly stays at the junction 5 of the bottom surface and the bottom of the side wall. It does not change the growth point of root by this. In addition, the bottom surface surrounded by the side wall 3 and the rib A 7 forms a recessed portion 6 of the bottom surface. In other words, while acting as a leg, water can be stored in this recessed portion, thereby maintaining the water retention of the entire cultured soil.

In addition, since the side walls are provided with a plurality of ribs in the vertical direction, the side roots of the cultivated plant can be guided downward along the ribs inside the circumferential wall, and then continue toward the drain hole along the ribs on the bottom surface (inner diameter direction). Can be derived. In other words, the roots are elongated in a spiral shape, and the inside thereof is hardly cavitation (so-called looping phenomenon), and the root cutting operation is unnecessary, thereby reducing damage to the absorbing muscles, which is inevitable for the nutrition of plants.

That is, thanks to these things, it is possible to cultivate seedlings with excellent lubrication after settlement.

Next, FIG. 5 is a partial perspective view showing a part of the seedling cultivation container 20 of the second embodiment, FIG. 6 is a partial plan view of the same cultivation container 20, and FIG. 7 shows the same cultivation container 20. It is a perspective view of one pollen body 21 which comprises, and FIG. 8 is a cross-sectional view along the DD line | wire of FIG.

In the figure, the cultivation vessel 20 is a plurality of cultivation vessels having substantially the same configuration as the cultivation vessel 10 of the first embodiment. Therefore, according to each pollen 21 provided in this cultivation container 20, the operation effect substantially the same as the operation effect which the cultivation container 10 of 1st Example has is obtained.

In addition, when the mold is formed of a synthetic resin having rigidity, the cultivation container 20 has an effect as a so-called 'plug tray'. And, if it is formed of soft synthetic resin, it can be used as a 'polyport' that can be applied to a cultivation tray having storage pockets opened at regular intervals in the longitudinal and horizontal directions, and a plurality of simultaneous insertions are made without inserting a single port one by one. As a result, the labor of the attachment work can be reduced, thereby improving work efficiency.

As above-mentioned, this invention is not limited to the cultivation container described in the said Example. In other words, it can be carried out by appropriately changing the design within a range not departing from the spirit of the present invention.

As described above, the cultivation container of the present invention according to each claim has a single potted plant with a bottom surface having a drainage hole at the center and an inclined circumferential wall whose diameter extends in the direction of continuous rising from the circumferential edge portion of the bottom surface. It is formed in a sieve shape, and in each pollen, where the plurality of swelled ribs are formed which extend radially from the center of the bottom surface to the side wall and the bottom surface and continue through the corner angles to the top of the inclined circumferential wall. There is a characteristic. Then, if necessary, one end is located in the vicinity of the side wall and the bottom surface instead of continuous in the drainage hole, and the interior extends radially from the center portion of the bottom surface and continues up to the top of the inclined circumferential wall through the corner portions. The rib expanded in the direction is formed.

The cultivation container of the present invention is very simple in structure, and since ribs are continuous in that there is no need to install a plurality of holes or slit holes in each pollen body, so that no new equipment investment or new mold is required. For example, even if the potted body is molded by a film processing method, as in the conventional case, that is, when the ribs are discontinuous at the corners of the potted body, the pulling force acts more strongly where the thickness of this part becomes thinner, so that cracks or pinholes do not occur. In addition, it can be said that it is very economically advantageous from the point which the moldability improvement and the yield are remarkably improved.

In addition, it is possible to obtain the remarkable effect shown next which is not seen in such a conventional cultivation container.

(1) The rib of the side wall can increase the strength of the side wall itself, the rib of the bottom surface can increase the strength of the bottom surface itself, and the rib of the side wall lower end portion and the bottom circumferential edge portion are formed of a resin material during molding. Since they are melted and solidified to form a belt-like lump in the radial direction and are formed as discontinuous rib-shaped ribs inside the outer wall of the peripheral wall, the strength of corner portions at the bottom of the side wall and the peripheral edge of the bottom surface is particularly increased. Thanks to this action, the shape retention and strength of the entire cultivation container can be improved.

(2) Only one drain hole is formed in the center of the bottom surface, and since there are not a plurality of holes or slit holes in the side wall or the bottom surface, there is little outflow of the culture soil, and thus, expensive culture soil can be used without waste. It can increase the amount of roots.

(3) The bottom rib has a contiguous configuration in the drainage hole, whereby the root is difficult to corrode because water supplied is difficult to stay in the junction between the bottom and the bottom of the circumferential wall. The growth point of the roots is not changed by this.

(4) Since the side walls are provided with a plurality of ribs in the up and down direction, the side roots of the cultivated plants can be guided downward along the ribs inside the circumferential wall, and then along the ribs on the bottom surface toward the drain hole (inside the diameter). Direction). In other words, the roots are elongated in a spiral shape, and the inside thereof is hardly cavitation (so-called looping phenomenon), and the root cutting is unnecessary, thereby reducing the damage of the absorbing muscles, which is inevitable for the nutrition of plants. That is, these can be added together and a seedling excellent in the sticking after fixation can be raised.

(5) In particular, if each cultivation container of Claims 3 and 4 is synthetic resin having rigidity, the effect as a plug tray can be obtained.

(6) And if it is a soft synthetic resin, it can be used as what is called a polyport applicable to the tray which has the storage pocket opened at the fixed interval in the vertical and horizontal direction.

In other words, instead of inserting a single pollen body one by one, a plurality of pollen bodies can be inserted at the same time, thereby reducing labor of the attachment work and improving work efficiency.

Therefore, the cultivation container of the present invention according to each claim can be said to be very effective.
