DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant cultivation apparatus for cultivating trees and the like by filling cultivation containers with cultivation soil.

[0002]

2. Description of the Related Art With the change of living style in recent years, cultivation containers such as flowerpots and planters are often installed on a veranda to grow plants in general homes, and in office buildings and stores. Also, plants are cultivated using balconies or rooftops to set up cultivation containers or make gardens.

In plant cultivation in such ordinary households, office buildings and stores, cultivation using artificial soil is performed in order to reduce the weight of the cultivation apparatus. For example, when cultivating plants with planters, hydroponics is performed exclusively from the perspective of facilitating daily management.After removing all soil from plants grown in soil cultivation, the soil is cultivated by artificial cultivation. After that, hydroponics is continued. In the case of cultivating plants with a rooftop as a garden, waterproofing is applied to the floor, artificial soil is laid on the floor, plants are planted, and plants are grown while supplying water.

[0004]

However, the above-mentioned plant cultivation has the following problems.
For example, when plants are hydroponically cultivated in a planter, it takes a lot of time and money to acclimate the plants grown in soil cultivation for hydroponic cultivation. I do. Further, in the case of a tree having a large root pot, a planter must be naturally large, but the size of a single planter is naturally limited.

[0005] In addition, when the roof is turned into a garden, a large amount of cost is required for waterproofing the floor and supplying water. Furthermore, since trees naturally rot and die when immersed in water, the artificial soil must be thickened so that water does not accumulate in the root cultivation. Therefore, a large amount of soil is required.

[0006] It is an object of the present invention to provide a plant cultivation apparatus which hardly causes root damage to the plant, requires less cultivation soil, and is inexpensive.

[0007]

According to a first aspect of the present invention, there is provided a plant cultivating apparatus comprising: a first container having an open upper portion; a second container having an open lower portion; The container is provided with a drainage hole of a size that does not allow artificial soil to pass through at a height position corresponding to the upper surface of the second container when the second container is placed. This is a plant cultivation apparatus provided with a water passage hole having a size that does not allow artificial soil to pass through.

[0008] According to this plant cultivation apparatus, the second container smaller than the inside method of the first container is placed in the first container, so that the filling amount of the cultivation soil can be reduced, and the first container can be filled in the first container. Since the water level in the first container is lower than the upper surface of the second container due to the provided drain holes, the trees are planted so that the root pot comes to the upper part of the second container even when cultivating trees. ,
The roots are not submerged in water and no root rot occurs. Water is supplied to the roots by raising the soil layer by capillary action. Here, when the floor surface is inclined, a difference in elevation may be provided at the position of the drainage hole provided in the first container.

[0009] The material and shape and size of the first container are not particularly limited, and the weight and weight of the container can be carried by a person.
Any size may be used as long as it can be installed on a veranda, balcony, or the like as it is, or can be assembled and installed. From the point of weight reduction and cost reduction, it is desirable to use a synthetic resin.Use a container such as an existing planter as it is, or use a container made by raising the periphery of the impermeable sheet to the top. Can be.

[0010] The material and shape of the second container are not particularly limited as long as they are lower in height than the first container and can be placed in the first container. As with the first container, a container made of a synthetic resin is desirable from the viewpoint of weight reduction and cost reduction. A plurality of the second containers can be placed inside the first container. Here, when a plurality of second containers are placed in a place where the floor surface is inclined, the second containers having different heights may be used according to the height difference.

[0011] The plant cultivation container according to claim 2 of the present invention, wherein a plurality of first containers in which the second container is placed are connected in series, and an outer shell of the first container group connected in series. This is a plant cultivation apparatus provided with a wall body for holding cultivated soil at the upper part of the cultivation.

When a plurality of first containers are connected in series, it is desirable that the floor surface is flat so that the height of the upper edge of each container is at the same level. When there is a step on the floor surface and the upper edge height of each container is different, the height of the wall may be determined based on the upper edge height of the uppermost container. In addition, it is desirable that the edges of the containers are closely contacted so that the soil is not leaked from the gap between the edges of the containers adjacent to each other.

The wall for holding the cultivation soil is for increasing the filling height of the cultivation soil so that a tree with a large root pot can be cultivated. A metal or concrete auxiliary member is assembled into a wall.

With such a structure, a cultivation container having a larger area and a larger internal volume than that of the plant cultivation container according to the first aspect can be obtained, and a large number of trees can be cultivated. . Also in this case, a plurality of second containers can be placed in the first container.

As the cultivation soil used in the present invention, any of the conventional cultivation soils for plant cultivation, including artificial soil cultivation, can be used. The use of stone is optimal. Foam brick is a hard and porous artificial soil obtained by firing clay at a high temperature of about 1200 ° C. and foaming the clay. Because it is hard, it is difficult to collapse during use by filling it in a container, and there is a gap between the foam bricks, so that water is well penetrated by capillary action, and because it is porous, it will be many if immersed in water The water is stored in the pores and the water retention is high.
