Abstract

PROBLEM TO BE SOLVED: To provide a seedling raising container useful for rice plants and vegetables, etc., capable of reducing the drying of bed soil, preventing the growth irregularities of seedlings, easily managing watering and improving the manpower saving, by making the end of a water discharge hole radially extended from the center part of a bottom reach the recessed part of the bottom. SOLUTION: The recessed part 5 is formed around the bottom 2 and the end of the water discharge hole 3 radially extended from the center part of the bottom 2 in three or four directions reaches the recessed part 5. Also, it is preferable to radially form the water discharge hole 3 by continuing three round holes 3a provided on the recessed part 5 with equal intervals to the round hole 3b at the center by connection grooves 3c.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling container for growing seedlings such as rice and vegetables.

[0002]

2. Description of the Related Art As shown in FIG. 1, a small container 1 is called a pot, a cell, or the like. Has become.

[0003]

The container is provided with a drain hole 3 whose bottom 2 is formed in a concave spherical or planar shape and extends radially from the center thereof. When raising seedlings by placing them on wire mesh or the like and floating from the ground, the roots are prevented from extending from the drainage holes 3 and effective, but the soil in the container 1 dries quickly and the number of times of irrigation increases, There is a possibility that the growth of the seedlings among the plurality of containers 1 may be irregular. A continuous concave portion is formed on the outer periphery of the flat bottom, and a round drain hole is provided at the center of the bottom 2. However, there is a possibility that the root wound in the concave portion may cause root rot due to water collected in the concave portion. . Also, according to the latter, the roots are excessively wound in the recesses and the growth of roots at the upper part is delayed, the roots are cut off midway when the seedlings are extracted from the container, or the growth of new roots after transplantation is delayed and the crop is There was a problem such as insufficient growth.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a concave portion 5 is formed around a bottom 2 and the bottom 2 is formed.
Of the drainage hole 3 extending radially in three or four directions from the center of the seedling reaching the concave part 5.

[0005]

Next, an embodiment of the present invention will be described. A plurality of pots (containers) 1 arranged in front, rear, left and right are integrally provided on a flexible plate 4 to form a seedling box (FIG. 2). The pot 1 and the plate 4 are made of the same resin.

The pot 1 is formed in a truncated frusto-conical shape, and has a continuous semicircular recess 5 formed on the outer periphery of the bottom 2 (FIGS. 3 and 4). A drain hole 3 is provided at the bottom. This drain hole 3 is formed in a radial manner with three round holes 3a provided at equal intervals in the concave portion 5 connected to a central round hole 3b by a connecting groove 3c, and the bottom 2 is divided into three pieces to form a valve. It has become.

[0007] The pot 1 is filled with floor soil, and seeds of rice and vegetables are sown and covered with the soil, and after a predetermined number of days have elapsed while watering is repeated, the seeds grow from the seeds, and the seedlings grow. At this time, the irrigated water appropriately accumulates in the concave portion 5 between the round holes 3a. When the seedlings grow to a predetermined length, the grown roots
A root pot is formed by entanglement in the inside. When the stick is pushed from below the bottom 2, the bottom 2 opens like a valve, the stick enters the pot 1, and the root pot is pushed out together with the seedling.

As shown in FIGS. 5 and 6, a container (cell) 1 is made of a hard resin, and a plurality of cells arranged in front, rear, left and right can be integrally formed to form a cell tray. The container 1
Is provided with a plurality of vertically elongated slits 7 in a side wall 6 and a round drain hole 8 in the center of the bottom 2. According to this configuration, a part of the floor soil packed in the container 1 is exposed to the air or the wind by the slit 7, so that an excessive root winding can be prevented. Further, when the cell tray is immersed in water to irrigate the floor soil, water permeates the floor soil from the slit 7 as well, so that watering is performed in a short time. Further, when water is sprayed on the floor soil after sowing, the state of irrigation can be determined through the slit 7.

The container 1 can be formed in a truncated pyramid shape as shown in FIG. As shown in FIGS. 8 and 9, an arc-shaped narrow drain hole 9 can be provided on the outer periphery of the flat bottom 2. That is, in the container 1 having the flat bottom 2, there is a possibility that root rot may occur due to the water collected on the outer peripheral portion. However, according to the above configuration, the water is removed from the drain hole 9, so that the above problem is solved. Will be resolved.

As shown in FIGS. 10 and 11, when a round drain hole 8 is provided at the center of the flat bottom 2 and a slit-shaped drain hole 10 is also provided at the lower portion of the side wall 6, the above-mentioned problem is similarly solved. Is reduced. As shown in FIGS. 12 and 13, an arc-shaped drain hole 11 extending between the bottom 2 and the side wall 6 can be provided at the intersection of the bottom 2 and the side wall 6. That is, depending on the crop, the root may be excessively wound at the intersection of the bottom 2 and the side wall 6, which may cause a delay in rooting in the upper half of the container 1.
The wound root comes into contact with the air from the drain hole 11 to stop further growth, and the rooting thereon becomes active.

As shown in FIG. 14, FIG. 15, and FIG.
Is formed in a frusto-conical shape or a frusto-conical pyramid shape, and a drain hole 12 can be provided on the bottom surface 2 and the side wall 6. At this time, the pushing tool 13 in which the pushing plate 13b protrudes from the flat plate 13a.
(FIGS. 17 and 18) are prepared, the container 1 where the seedlings have grown is placed on the extruder 13, and the container 1 is pushed down. Then, the extruded plate 13b enters the drain hole 12 and pushes up the seedling, so that the seedling easily comes out of the container 1.

[0012]

As described above, according to the present invention, the concave portion 5 is formed in the outer peripheral portion of the bottom 2 of the container 1, and the concave portion 5 is divided into three or four by the radial drain holes 3, and the floor in the container 1 is formed. Part of the water irrigated in the soil appropriately accumulates in the recess 5 between the drain holes 3 to prevent the floor soil from drying. Therefore, the drying of the floor soil is reduced, and the uneven growth of the seedlings can be prevented, and the management of irrigation becomes easy.
