Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a plant pot used in the initial stage of growing plants such as trees and vegetables.

[0002]

[Prior art]

 Conventionally, when growing plants such as trees and vegetables, at the initial stage, they are grown using relatively small plant pots, and when they grow to some extent, they are replanted in plantations, flower beds or fields. There is.

[0003]

[Problems to be solved by the device]

 By the way, when replanting a grown plant in this way, there is a risk that the roots and stems will be damaged when the plant is taken out of the plant pot and when the taken out plant is planted. There is a problem that it requires labor.

The present invention has been made in view of such conventional problems, and it is an object of the present invention to provide a plant pot that does not damage a plant at the time of repotting and can be easily replanted. To aim.

[0005]

[Means for Solving the Problems]

 The plant pot according to claim 1 of the present invention is a plant pot in which a plant is planted in order to achieve the above-mentioned object, and when it is buried in soil, it is decomposed by microorganisms in the soil. It is characterized by being formed of biodegradable plastics.

A plant pot according to a second aspect of the present invention is the plant pot according to the first aspect, wherein the biodegradable plastic is mixed with a fertilizer that dissolves in the soil when the biodegradable plastic is decomposed. There is.

A plant pot according to a third aspect of the present invention is characterized in that, in the first or second aspect, the wall portion has a corrugated cross section.

Further, the plant pot according to claim 4 of the present invention is the plant pot according to any one of claims 1 to 3, wherein the wall portion has a through hole into which the root of the plant is inserted. doing.

[0009]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In these drawings, reference numeral 1 indicates a plant pot according to the present embodiment. The plant pot 1 is formed on a bottomed cylinder whose top is open, and its bottom has a smaller diameter than the top. Is formed in a substantially truncated cone shape.

The plant pot 1 is made of biodegradable plastic that is decomposed by microorganisms in the soil when it is buried in the soil such as a forest or a field.

As the biodegradable plastic, for example, Matterby (trade name; manufactured by Nippon Synthetic Chemical Co., Ltd.), Bionole (trade name; manufactured by Showa High Polymer Co., Ltd.), or the like is used, and injection molding or blow molding is used. It is formed into a predetermined shape and a predetermined thickness by using a forming means such as forming or vacuum forming.

Further, in this embodiment, a plurality of through holes 2 having a predetermined inner diameter are formed in the peripheral wall 1a and the bottom wall 1b of the plant pot 1, as shown in FIGS. The roots that grow with the growth of the plant planted in the tree pot 1 are guided to the outside of the plant pot 1 through these through holes 2.

As shown in FIG. 3, the plant pot 1 according to the present embodiment configured as described above has a plant T, which is an initial stage of growing, planted in a cultivation shelf P or the like outdoors or in a house as shown in FIG. Be cultivated.

When the plant T grows to a certain extent, it becomes necessary to replant the plant T in a plantation, a field, or the like. Such replanting work is performed as shown in FIG. It is performed by embedding the root in the ground A together with the plant pot 1.

In the plant T replanted in the ground A together with the plant pot 1 in this way, the root Ta grows as the plant grows, but a large number of through holes 2 are provided in the wall of the plant pot 1. As a result, the root Ta extends to the outside of the plant pot 1 through these through holes 2, and the root Ta is widely spread in the ground A.

In addition, after the plant T has been replanted, the plant pot 1 is gradually biodegraded by the microorganisms in the ground A with the passage of time, so that the root part of the plant T is released into the ground A. And is integrated with the underground A.

Therefore, in the plant pot 1 according to the present embodiment, when the plant T is replanted, the plant T is replanted by digging a hole in the ground and embedding the hole together with the plant pot 1. It is not necessary to remove the plant pot 1 from the plant, and as a result, the plant T can be replanted without damaging the roots and stems of the plant T, and the planting work is simplified.

On the other hand, since the decomposition time of the plant pot 1 depends on the volume of the plant pot 1 when the soil condition to be embedded is constant, the plant pot 1 is cultivated by adjusting the thickness of the plant pot 1. It is possible to adjust the decomposition time according to the type of plant T.

Further, when the plant pot 1 is molded, by mixing a fertilizer or a pesticide into the molding material, when the plant pot 1 is disassembled, the fertilizer or the pesticide dissolves in the ground A, After the replanting, the fertilizer is supplied to the plant T or the soil is reformed automatically.

Further, as described above, when it is attempted to shorten the biodegradation time by adjusting the thickness of the plant pot 1, it can be considered that the thickness of the plant pot 1 becomes thin and its strength decreases. In such a case, as shown in FIGS. 5 and 6, the lateral cross-sectional shape of the plant pot 1 is corrugated so as to form the uneven portion 3 along the height direction on the peripheral wall 1a. As a result, the decrease in strength is suppressed.

With such a configuration, the adjustment range of the biodegradation time of the plant pot 1 is widened, and an appropriate repotting process according to the type of the plant T becomes possible.

The shape, size, etc. of the plant pot 1 shown in the above embodiment are examples, and can be variously changed based on the type of plant to be cultivated, design requirements, and the like.

For example, in the above-described embodiment, an example in which the through hole 2 provided in the wall portion is a round hole is shown, but it may be in a mesh shape. By forming the through hole 2 having such a shape, the degree of opening thereof is adjusted and spillage of the soil in the plant pot 1 is suppressed without hindering the overhang of the root Ta.

[Effect of the invention]

 As described above, according to the plant pot according to claim 1 of the present invention, since the plant pot is formed by the biodegradable plastic that is decomposed by the microorganisms in the soil, the plant pot can be used in the initial stage of plant cultivation. When the plants are cultivated on the ground in a pot, and when they are replanted in a forest or a field when the cultivating progresses to a certain extent, the root part of the plant is embedded with the plant pot, and the plant pot is biodegraded in the soil. , You can replant without removing the plant pot.

Therefore, it is possible to prevent the roots and stems from being damaged at the time of repotting, and it is possible to repot by a simple operation of burying the plant pot in the soil.

According to the plant pot of claim 2 of the present invention, the fertilizer is mixed in the biodegradable plastic so that the fertilizer is dissolved in the soil when the plant pot decomposes in the soil. As a result, it is possible to automatically supply the fertilizer to the plant after replanting and simplify the cultivation of the plant.

According to the plant pot of claim 3 of the present invention, the wall of the plant pot has a corrugated cross-section to increase the strength of the wall and reduce the thickness of the pot. Can be realized.

Accordingly, the thickness adjustment range of the plant pot is increased, and the biodegradation rate adjustment range of the plant pot is increased, whereby the plant pot can be decomposed at a speed suitable for the plant. .

Further, according to the plant pot of claim 4 of the present invention, by forming the through hole into which the root of the plant is inserted in the side wall, the root that grows as the plant grows is provided outside the plant pot. It is possible to lead to roots and to grow naturally, and after replanting, roots can be smoothly crawled into the soil.
