However, when trees grown using a conventional synthetic resin cultivation container are planted in a predetermined planting place, it is necessary to remove the synthetic resin cultivation container. It is necessary, troublesome and troublesome.In addition, the roots of the trees are damaged when they are taken out of the cultivation container, the tree vigor is weakened, the survival rate after planting and the subsequent growth are very poor, and the trees die.

On the other hand, when a conventional biodegradable cultivation vessel is used, trees after cultivation can be planted as they are without removing them one by one from the cultivation vessel, so that the planting work efficiency can be improved, and industrial waste can be improved. It has been thought that the labor and cost of processing as a product can be eliminated. However, according to the conventional planting method using biodegradable cultivation vessels, the decomposition rate is affected by the microbial environmental conditions in the soil at the embedding site and the irrigation environment conditions, etc. If the walls of the cultivation container are not decomposed and destroyed, the roots that have become rooted will break the wall of the cultivation container and cannot protrude to the outside. It is necessary to bury all of the cultivation vessels in the soil, and the work is troublesome and troublesome. With the growth after planting, the roots of the trees grow in the bottom holes formed in the biodegradable cultivation vessels. Above the diameter, the root becomes clamped by the inner peripheral wall of the bottom hole. In other words, as a result, problems such as causing a so-called strangulation state such as interruption of nutritional supplementation due to the tightening of the root by the inner peripheral wall of the bottom hole and eventually causing death will become apparent.

That is, the conventional method of planting a plant in which a biodegradable cultivation vessel is buried in soil can eliminate the trouble and cost of treating it as industrial waste, but, for example, it is necessary to remove trees one by one from the cultivation vessel. It is necessary to remove it and plant it in the planting site, or it is necessary to bury all of the cultivation containers in the soil, so it takes time and work efficiency is extremely poor,
Because the nurturing environment conditions on the tree side, especially the growth conditions of the roots, are ignored, the view that this is an unrealistic method of planting is dominant.

In the figure, a biodegradable cultivation container 10 of the first embodiment includes a cylindrical side wall 2 ending at an opening edge at an upper end side, and a bottom wall 3 continuous with an axial lower end side of the side wall 2. A pot body 5 having a cultivated soil storage chamber 1 having a circular cross section formed by a side wall 2 and a bottom wall 3. A pellet mainly composed of a mixture of polylactic acid and starch is formed into a predetermined shape by a blow molding method. It is manufactured by drilling four corner holes 6 in the continuous portion 4 between the side wall 2 and the bottom wall 3. For example, after growing a tree T in the open field for 2 to 3 years, it is planted as it is. It can be embedded in a state where the upper end of the side wall 2 protrudes from the soil surface at the planting site while the tree T is being transported to the ground W and the tree T is still contained therein. However, the cross-sectional shape of the pot body 5 is not limited, and may be a circular shape, a rectangular shape, or another shape.

Further, as shown schematically in a schematic perspective view in FIG. 5, six corner holes 6 may be formed. That is, the corner holes 6 may be formed in the continuous portion 4 between the bottom wall 3 and the side wall 2, and the number, size, etc. thereof can be appropriately changed in design, and the shape thereof is also circular. The design can be appropriately changed to various shapes such as a rectangle or a band.

In this biodegradable cultivation container 10, the biodegradable resin is gradually decomposed even when the tree T is grown in the open ground for two to three years, but by adjusting the mixing ratio of polylactic acid and starch. , The decomposition time can be controlled, and when buried in the planting site W, the microbial decomposing action in the soil is added, it is rapidly decomposed and falls apart, part of which is consumed as plant nutrients You.

Incidentally, such a conventional biodegradable cultivation container 20 has been developed by giving importance only to its biodegradation characteristics, and neglecting the viewpoint of an optimum breeding environment for trees T, such as ventilation characteristics and drainage characteristics. It is probably because these cultivation containers 2
In order to plant 0 in a state in which the tree T is contained, the tree T must be entirely buried in the soil as it is.

The reason for this is that although the biodegradable cultivation container is used, its decomposition rate is greatly affected by the soil, especially the microbial environment, irrigation environment and the like. It was not possible to do so individually. In other words, if the whole is entirely buried in the soil as it is, even if the air permeability and water permeability of the side wall 23 are impaired, as shown schematically in FIG. Although it can climb over the top surface and extend into the outer soil and be firmly rooted, for example, when the upper end of the side wall 23 is not buried in the soil, the root once protrudes from the soil into the atmosphere and the top surface of the side wall 23 is removed. Unless it stretches out and reenters the soil, it cannot take root in the outer soil. For this reason, the roots of the trees T are not only prevented from growing steadily, but also cause root rot and rot, and eventually caused death.

Further, since only one bottom hole 22 is formed near the center of the bottom wall 21 of the conventional biodegradable cultivation container 20, the main root of the tree T is directed outward from the bottom hole 22. As shown schematically in FIG. 7, when the biodegradable cultivation container 20 does not decompose but the bottom wall 21 is not decomposed and thus the bottom hole 22 does not become large, although the bulging and extending continue to thicken as it is. However, the main root is gradually squeezed every day by the inner peripheral surface of the bottom hole 22, and eventually becomes a so-called strangled state and dies (the mortality is 10% or more). Therefore, it has been concluded that the conventional planting method of directly embedding in the planting place T using the biodegradable cultivation container 20 is unrealistic due to the added work efficiency. It is.

On the other hand, the biodegradable cultivation container 10 of the first embodiment has biodegradation characteristics, and has four corner holes 6 in the continuous portion 4 between the side wall 2 and the bottom wall 3. Since it is perforated, it is possible to appropriately maintain both the water retention environment and the ventilation environment through the corner holes 6, so that root rot can be prevented and
The entanglement of the root becomes good. After the planting, the soil at the planting site and the cultivation in the pot body 5 are connected to each other, and an effect of substantially homogenizing the environmental conditions of the soil is added. As shown in FIG. 2 Without getting over the top
It can extend from the corner hole 6.

That is, unlike the conventional biodegradable cultivation container 20, the upper end of the side wall 2 can be buried even in a state where it protrudes from the surface of the soil, and it is necessary to take out the trees T one by one and plant them. Since there is no such work, labor saving and efficiency improvement of the implantation work can be achieved. In addition, since the planting can be performed without damaging the roots, and the roots can continue to grow smoothly outside the pot body 5 after the planting, the optimum growth environment of the plant can be maintained and the vigor does not decline.
