JPH1156115A - Plant seedling growing pot and seedling growth therewith - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a seedling growing pot not harming its roots, caused by the collapse of the shape of a soil containing the roots during transportation to stop its growth temporarily or reduce its rooting rate after its permanent plantation, and a method for growing the seedling therewith. SOLUTION: This plant seedling growing pot 1 comprises a double structure composed of an outer pot consisting of a non-biodegradable material and an inner pot consisting of a biodegradable pot. In the cultivation of a plant, etc., by using the same pot, a pot-shaped rots consisting of the biodegradable material tangled with elongated root parts is formed and a root strike is performed after removing such pot-shaped roots from the outer pot.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for growing and cultivating plants such as green flower seedlings, fruit tree seedlings, flowering seedlings and vegetables, and a seedling raising method using the same.

[0002]

2. Description of the Related Art Conventionally, for example, in growing green flowering trees,
In general, transplantation is carried out at each stage from a seedling to a high tree to an adult tree, and after sowing and raising a seedling, the seedling is grown to a certain size, then extracted and planted.

[0003]

However, for example, when a plastic pot is used as a cultivation container, the shape of the soil including the root collapses during transportation due to the softness of the material, causing damage to the root and growing. May temporarily stop or the survival rate after planting may decrease. Therefore, there is a problem that careful handling is required for the handling, and restrictions are imposed on a transplant timing, a transplant place, and the like. The present invention solves this problem with a special configuration of a double pot structure made of different materials.

[0004]

That is, the present invention relates to a plant raising seedling pot having a double structure of an outer pot made of a non-biodegradable material and an inner pot made of a biodegradable material, as well as a tree or the like thereby. The present invention relates to the provision of a seedling raising method characterized by forming a root pot made of a biodegradable material in which elongated roots are entangled, removing the root pot from an outer pot, and performing rooting.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A cultivation container according to the present invention is shown in FIG.
As shown in FIG. 2, the outer bowl 1 has an inner bowl 2 and the inner bowl 2 is accommodated in the outer bowl 1. The outer bowl 1 is a bottomed container in which the side and bottom surfaces are integrated by any means such as adhesion or sewing, and has an arbitrary size and shape according to the target of the growing plant. In particular, it is preferable that the shape be a cone having an angle of about 45 ° ± 5 °, or a conical shape, since the stability when transporting the rollover is good. The constituent material is preferably made of a synthetic fiber such as a non-biodegradable polyolefin fiber, a polyester fiber, and a polyamide fiber, which is lightweight and hardly deteriorates even when buried in the ground for a long time by a spun bond method. Continuous long-fiber non-woven fabric, or various knitting and weaving, if necessary heat roll, embossing, heat treatment such as calendering, or acrylic ester resin,
Pads, gravure coating, and knife coating are used to adjust the air permeability and the penetration resistance of the root by using methacrylate resin, epoxy resin, or the like, but may be made of ceramic, porcelain, or metal.

On the other hand, the inner bowl 2 is made of, for example, a cellulosic material such as cotton, hemp, coconut, or the like, or a biodegradable plastic material such as aliphatic polyester, which is degraded due to deterioration in strength in a natural environment. In the same manner as described above, a non-woven fabric, a knitted fabric, a woven fabric, or a simple mat-like material is used, but if necessary, the above-described processing may be performed. The shape and size of the inner bowl are
Although the shape and size can be accommodated in this, it may be a bottomed shape or a bottomless shape, or may be a configuration simply wound around the inner periphery of the outer bowl. However, the upper edge is preferably shorter than the outer bowl as shown in FIG. 1 in order to prevent the evaporation of water, and when used, the part is hidden in the soil as shown in FIG. Is preferred.

[0007] The nursery pot of the present invention having the above structure is shown in FIG.
As shown in (1), soil 3 is put into the plant, trees 4 and the like are planted, seedlings are raised for a required number of days, and then transplanted. At the time of such transplantation, as shown in FIG. 3, it is separated from the outer pot 1 and is planted as it is in a new environment. At this time, the grown fine roots enter the inner pot 2 and are entangled with each other, so that the roots do not collapse. Therefore, the fine roots are not damaged and the work can be performed smoothly, and the subsequent growth is positively affected. Further, since the inner pot is embrittled in a natural environment, corroded and decomposed and disappears, it does not adversely affect the growth, and therefore does not need to be removed. Further, the outer bowl 1 after being separated can be reused. Trees that are most suitable for the main cultivation container and the cultivation method include oranges, persimmons, and the like. In addition, since the damage at the time of transplantation is small as described above, transplantation is possible regardless of the season, and transplantation under severe conditions such as slopes is also possible.

Hereinafter, the present invention will be described with reference to embodiments.

Example 1 A 5 mm-thick nonwoven fabric made of coconut fiber was wound around the inner wall of an outer pot (5-inch diameter) made of vinyl chloride to form an inner pot. At this time, lower the upper edge of the inner pot by about 3 cm from the upper edge of the outer pot, cover the soil in the pot so that the upper edge of the inner pot is completely hidden, and allow rapid evaporation of water from the inner surface of the pot. I tried to prevent it. After that, cultivation was performed under the same conditions as general tree breeding. Planting and cultivation were carried out in April, and at the time of confirmation in November, the roots of Shirakashi were entangled with the coconut fiber non-woven fabric of the inner pot to form a firm root pot.

[0009]

Example 2 A biodegradable plastic net (Biopol (trade name: Zeneca Corporation) was placed on the inner wall of the same outer bowl as in Example 1.
And the test was conducted under the same conditions as in Example 1. As a comparative example, cultivation was performed under the same conditions using a container (only outer bowl) made of only a polypropylene nonwoven fabric.
The trees thus grown were rooted on a slope having a slope of 30 ° C. by 20 each, and the survival rate was evaluated. The results were as follows, showing an excellent survival rate.

[0010]

As described above, the present invention handles root mortars made of degradable materials, so that workability is good, and collapse during transportation and damage to roots are small. In addition, since it can be transplanted as it is, it shows an excellent survival rate and there is no suspension of growth. In particular, it shows an excellent transplantation effect even in harsh conditions such as slopes, even in a season when transplantation is difficult, such as in summer. Furthermore,
Being able to recycle the removed outer bowl leads to resource saving. In addition, you may mix a fertilizer, a pesticide, etc. in the constituent material of an inner bowl. The application of the method is wide regardless of vegetables, trees and the like, and its use such as sowing and raising seedlings is arbitrary.
