DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nursery set and a nursery method used for raising cultivated products such as flowers, seedlings and vegetables.

[0002]

2. Description of the Related Art Conventionally, a seedling set of this kind has a cup-shaped seedling pot made of a synthetic resin such as vinyl having only a pot drainage hole at the bottom, and the seedling pot is attached to and detached from a lattice-shaped pot mounting portion. Some trays are formed so that a plurality of trays can be mounted as much as possible. According to the conventional seedling raising method using the seedling raising set, the plants grown in the seedling raising pot are mounted on a tray together with the seedling raising pot and transported to a field or the like. When planting in soil, the seedling raising pot is removed from the tray, and further grown plants are removed from the seedling raising pot. However, in the conventional seedling raising method described above, the operation of planting the grown plant in the soil is twice as troublesome as the operation of removing the seedling pot from the tray and the operation of removing the plant from the seedling pot, which is troublesome. In addition, when the plant is removed from the seedling raising pot, the root of the plant may be caught by the pot drainage hole and cut off, or the soil in the pot may collapse, resulting in damage to the root. Thus, in recent years, seedling pots formed of soft organic fibers that are decomposable are sometimes used. The seedling pot is planted in the soil together with the grown plant, and is naturally decomposed by the microbial decomposition action in the soil. According to this conventional seedling raising pot, in the process of raising seedlings before being planted in the soil, the tips of the grown roots penetrate the peripheral wall of the pot and are irradiated with light such as sunlight to dry and grow. Stop. Therefore, the pot made of the soft organic fiber is not broken by the growth of the root. Then, when the plant is planted together with the pot in the soil, the pot gradually decomposes in the soil, and the roots in the pot grow again while breaking the pot.

[0003] However, in the latter seedling raising pot, the root growth is temporarily stopped by light irradiation as described above in the seedling raising process before planting in the soil, and even after planting in the soil, Since the root growth is stopped until the pot undergoes microbial degradation, there is a disadvantage that the growth rate of the plant is reduced.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to plant a plant together with a seedling-raising pot in soil and to hinder the growth rate of the plant. And a method of raising seedlings.

[0005]

Means for Solving the Problems As a technical means of the present invention for solving the above problems, a first aspect of the present invention is a nursery pot made of a naturally degradable material, and a plurality of the nursery pots are detachably mounted. In a seedling raising set comprising a tray, the seedling raising pot has a plurality of root holes in a peripheral side wall and a bottom portion is formed so as to be able to drain water, and the tray is a pot mounting part to which the seedling raising pot is attached and detached. The pot mounting portion is formed so as to close the root hole of the seedling growing pot to be mounted and to drain water. Here, the root hole is a plurality of penetrating holes formed on the peripheral side wall of the seedling raising pot, and is formed so as to allow the roots of growing plants to pass therethrough. When formed, the mesh is also included. Also,
The above-mentioned naturally degradable material means a material which is naturally degraded by a microbial decomposition action in soil, for example, biodegradable mixed plastics, organic fibers such as hemp, pulp chips, paper, a mixture of compost and flour. And so on. And
The seedling raising pot is formed by forming the above-described material into a cup shape or a cylindrical shape with a narrowed bottom. Further, specifically, the tray may be one in which a plurality of pot mounting portions are integrally formed by resin molding. As a preferred specific configuration of the pot mounting portion, the pot mounting portion has a cup shape with an upper opening following the seedling raising pot, and closes the passage hole at the peripheral side wall and drains water from a tray drainage hole formed at the bottom. It is composed of In addition, the above-mentioned soil means soil at the next stage in which the plants grown in the seedling raising pot are planted, and specifically, soil such as fields and flower fields, soil put in planters and pots, and the like. Including.

According to a second aspect of the present invention, a seed or a seedling of a plant is planted in each of the seedling pots which are mounted on the tray and in which a predetermined amount of soil is put, and the seedling pot is still mounted on the tray. Cultivating the plant, and when the plant reaches a desired growth, each of the seedling pots is removed from the tray, and the plant is planted together with the seedling pot in soil. It is preferable that a predetermined amount of soil is put in the tray after a plurality of seedling raising pots are attached to the tray in order to prevent the put soil from spilling from the root hole. If there is not much soil spilling from the root hole due to clay or the like, it may be before a plurality of seedling raising pots are attached to the tray.

According to the above technical means, the present invention has the following effects. The seeds or seedlings of the plants planted in the seedling raising pot are raised while being attached to the tray.
Since the seedling raising pot has a plurality of root holes on its peripheral side wall, the tip of the root of the grown plant is inserted through the root hole.
The root that has passed through the root hole is not stopped from growing by drying due to irradiation with light such as sunlight because the pot mounting portion of the tray blocks the root hole. During cultivation, the water supplied into the seedling raising pot is drained to the outside through the drainable bottom of the pot and a tray.

[0008] Plants that have reached the desired growth are removed from the tray and planted together with seedling pots in the desired soil.
The plant planted together with the seedling growing pot grows while passing its root through the root hole until the seedling growing pot collapses due to the microbial decomposition action in the soil. Then, as the roots grow, microbial decomposition of the seedling raising pot also proceeds, so that the seedling raising pot is pushed and broken by the growing root, and the root further grows.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an example of a nursery set and a nursery method according to the present invention.

A seedling raising set A includes a seedling raising pot 10 and a tray 20 on which a plurality of the seedling raising pots 10 are detachably mounted.
(See FIGS. 1 and 2).

The seedling raising pot 10 is formed by molding a naturally degradable material, that is, a biodegradable mixed plastic or an organic fiber which is naturally degraded by a microbial decomposing action in soil into a cup shape. A plurality of root holes 11 are formed to allow the roots 31 of the growing plant 30 to pass therethrough,
At the bottom, one or more pot drainage holes 12 for draining water supplied during seedling raising are formed.

The tray 20 is formed by integral resin molding on a surface of a rectangular flat plate portion 21 so that a large number of pot mounting portions 22 are opened at predetermined intervals and open upward.

The pot mounting portion 22 substantially imitates the outer surfaces of the peripheral side wall and the bottom of the seedling raising pot 10 and slightly protrudes the upper edge of the seedling growing pot 10 to be mounted so that the seedling raising pot 10 can be picked out. The seedling raising pot 10 has a cup shape formed slightly shallower than the seedling raising pot 10. The plurality of root holes 11 of the seedling raising pot 10 to be mounted are closed by the inner peripheral wall, and the tray drainage holes 23 formed at the bottom are used. It is formed so that it can be drained.

In the seedling raising method using the seedling raising set A having the above structure, first, the seedling raising pots 10 are mounted on a plurality of pot mounting portions 22 of the tray 20, and a predetermined amount of soil for raising seedlings is placed in the seedling raising pots 10. Can be put in. Then, seeds or seedlings of the desired plant 30 are planted on the medium (see FIG. 3A).

Next, with the seedling pot 10 mounted on the pot mounting portion 22 as described above, the plant 30 is cultivated, and the roots 31 growing in the seedling raising pot 10 extend downward and radially. Go. The seedling raising pot 10 mounted on the tray 20 is reinforced by the pot mounting portion 22 formed substantially following the outer surface of the peripheral side wall and the bottom of the seedling raising pot 10, so that it is wetted by water supply or rain during cultivation. It does not soften and collapse even if it is vibrated during transportation.
The root 31 extending downward is exposed from the tray drain hole 23, while the root 31 extending in the radial direction
0 reaches the inner surface of the peripheral side wall. Root 3 that has reached the inner surface of the peripheral wall
1, the root 31 reaching the root hole 11 passes through the root hole 11, the outer peripheral surface of the seedling raising pot 10 and the pot mounting portion 22.
Crawling between the inner surface of the peripheral side wall. At this time, since the root hole 11 of the seedling raising pot 10 and the peripheral side wall of the seedling raising pot 10 are closed by the pot mounting portion 22, the roots 31 extending in the radial direction are not irradiated with light such as sunlight. Therefore, the growth of the root 31 extending in the radial direction is not hindered.

When the desired growth of the plant 30 has been reached, the seedling raising pot 10 is removed from the tray 20, and the whole seedling raising pot 10 is planted in soil (see FIG. 3 (b)). The time of planting in the soil can be determined using the degree of growth of the leaves and stems of the plant 30 or the degree of extension of the root 31 exposed from the tray drain hole 23 as a guide. When judging the degree of elongation of the root 31 as a guide, the time when the root 31 that has grown in the radial direction has reached the root hole 11 can be set as the planting time on the soil. 1
Whether it has reached 1 can be estimated using the degree of extension of the root 31 exposed from the tray drain hole 23 as a guide. In addition, whether the root 31 grown in the radial direction has reached the root hole 11 is determined by temporarily removing the seedling raising pot 10 from the tray 20 and visually checking whether the root 31 is exposed from the root hole 11. May be.

The plant 30 planted in the soil together with the seedling raising pot 10 passes the root 31 through the passage hole 11 and the pot drainage hole 12 until the seedling raising pot 10 is microbially decomposed in the soil. It extends inward (see FIG. 3 (c)). Since the microbial decomposition of the seedling raising pot 10 progresses along with the growth of the root 31, the seedling raising pot 10 is eventually crushed by the growing root 31, and the root 31 further grows (FIG. 3).
(D)).

In the illustrated seedling raising set A, the pot drainage hole 12 and the tray drainage hole 23 are provided one by one, but may be provided at a plurality of locations. In addition, the pot drain hole 12 and the tray drain hole 23
It is preferable to set the positions to correspond to each other if the roots 31 of the plant 30 are exposed below the pot mounting portion 22 to observe the elongation thereof.

In the same seedling raising set A, the seedling raising pot 1
The root hole 11 of the plant 30 and the peripheral wall of the seedling pot 10 are closed by the pot mounting portion 22.
If the plant 1 is to be planted in the soil when it has reached the root hole 11, at least the root hole 11 is partially
It may be configured to be closed by a.

Next, another embodiment of the seedling raising set B shown in FIGS. 4 and 5 will be described. The seedling raising set B includes a seedling raising pot 40 and a tray 50 on which a plurality of the seedling raising pots 40 are detachably mounted.

The seedling raising pot 40 is formed by molding the same naturally degradable material as the seedling raising pot 10 into a cup shape.
On the peripheral side wall, two opposing root holes 41, 41 are formed, and at the bottom, one or a plurality of pot drainage holes 42 for draining water supplied during seedling raising are formed.

The root hole 41 has a larger square hole shape than the root hole 11 of the seedling raising set A, and allows the root of a growing plant to pass therethrough. It is placed on the upper surface of the hook piece 51a.

The tray 50 is formed by integral resin molding so that a large number of pot mounting portions 51 are arranged at predetermined intervals. The pot mounting portion 51 is provided with two opposing hook pieces 51a in a substantially circular frame. Hook piece 51a
5 has an inverted L-shape in vertical section as shown in FIG. 5, and slightly protrudes toward the center of the pot mounting portion 51 to engage with the root hole 41 of the seedling growing pot 40 so that the inner surface of the seedling growing pot 40 can pass therethrough. It is formed so as to close the root hole 41 and receive the upper side 41a of the root hole 41 of the seedling raising pot 40 on the upper surface.

According to the seedling raising set B, when the seedling raising pot 40 is mounted on the tray 50, each of the two root holes 41, 41 becomes the two hook pieces 5 of the tray 50.
1a, 51a, the two root holes 4
Since the roots 1 and 41 are closed, the roots extending in the radial direction in the seedling raising pot 40 are not hindered from growing by irradiation of light such as sunlight. Then, when the seedling raising pot 40 is planted in the soil, the plants in the seedling raising pot 40, as in the case of the seedling raising set A described above, until the seedling raising pot 40 is microbially decomposed in the soil, It passes through the root hole 41 and the pot drainage hole 42, extends into the soil, and grows.

Next, another embodiment of the seedling raising set C shown in FIGS. 6 and 7 will be described. The seedling raising set C includes a seedling raising pot 60 and a tray 70 on which a plurality of the seedling raising pots 60 are detachably mounted.

The seedling raising pot 60 is made of a naturally degradable material similar to that of the seedling raising pot 10 and is formed into a cup shape, and one or more vertically elongated slit-shaped root holes 61 are formed on the peripheral side wall. The seedling pot 1
A pot drainage hole 62 larger than the zero pot drainage hole 42 is formed.

The tray 70 is formed by integral resin molding so that a large number of pot mounting portions 71 are arranged at predetermined intervals. A plurality of vertically long walls 71a are formed on the peripheral side surface of the pot mounting portion 71 so as to cover the respective root holes 61 of the seedling raising pot 60, and a bottom surface 71b continuous from the lower end of the wall portion 71 is formed as a seedling raising pot. 60 is formed in a curved mountain shape with a vertical cross section that engages with the pot drainage hole 62, and a tray drainage hole 72 having a substantially cross shape in a plan view is formed on the bottom surface 71b. The tray drain hole 72 is provided on the bottom surface 71b.
The seedling pot 60 is formed in the shape of a mountain
Prevents the accumulation of water on the bottom of the pit, causing root rot. Reference numeral 71c in FIG. 7B indicates a hole portion formed between the vertically long wall portions 71a.

According to the seedling raising set C, when the seedling raising pot 60 is mounted on the tray 70, the seedling raising pot 6
0 is closed by each wall 71a of the tray 70, and similarly to the seedling raising set A and the seedling raising set B, the roots extending in the radial direction in the seedling raising pot 60 emit light such as sunlight. Irradiation does not hinder its growth. When the seedling-raising pot 60 is planted in the soil, the plants in the seedling-raising pot 60 transfer their roots to the root hole 61 and the pot drainage hole 62 until the seedling-raising pot 60 undergoes microbial degradation in the soil. It passes and extends into the soil and grows. At this time, since the pot drainage hole 62 is formed relatively large, the growth of the root particularly in the downward direction is promoted.

Next, the seedling raising pot 100 illustrated in FIG.
Requires a stapling core 91 (U-shaped bracket) to stop the sheet made of hemp fiber that can be naturally degraded in the soil with a stapler core 91 (U-shaped metal fittings) to process the root hole and drain hole It is a simple product that has a simple structure and high productivity.

The seedling raising pot 100 is, as shown in FIG.
By fixing the peripheral side wall with a stapler core 91, the bottom side is formed in a slightly constricted cylindrical shape. By being attached to a tray formed in the same manner as the seedling raising set A, the mesh and the bottom opening are formed. Are used by being closed by a peripheral side wall and a bottom portion of the tray mounting portion, respectively. Therefore, the roots extending radially and downward in the seedling raising pot 100 are not hindered from growing by irradiation of light such as sunlight.

When the seedling-growing pot 100 is planted in soil, the plants in the seedling-growing pot 100 remove the roots and the mesh of the peripheral wall and the bottom opening until the seedling-growing pot 100 decomposes in the soil. It passes and extends into the soil and grows. At this time, the bottom opening of the seedling raising pot 100 promotes the growth of the root particularly downward. When the seedling raising pot 100 is removed from the tray for planting in the soil, the plants in the pot 100 grow with the roots entangled in the vicinity of the bottom. rare.

[0032]

Since the present invention is configured as described above, it has the following effects. Since the root of the plant that grows through the root hole is closed by the pot mounting portion of the tray, the growth rate is not hindered by drying by irradiation with light such as sunlight.
When the grown plant is planted in the soil, the plant can be planted together with the seedling raising pot in the soil, so that the operation can be performed without cutting or damaging the root. Moreover, since the plants planted together with the seedling pots in the soil pass the roots through the root holes, the root growth is not hindered even before the seedling pots are degraded in the soil.
