Abstract

PURPOSE:To prevent root rot, by constituting containers of double structure, by forming a space part between the containers and setting a ventilating vent and an exhaust vent. CONSTITUTION:Containers 1 and 2 are made into a double structure, the inner container 2 is filled with cultivating soil 14, a plant is planted and the containers are placed in a water tank 16 having the bottom covered with a sheet 15 while maintaining the water level at the position of a ventilating hole at the bottom of the containers. Since the bottom of the containers is partially dipped in the liquid level, the cultivating soil is provided with water or a liquid fertilizer from a water inlet hole 5 and a drain hole 6 by capillary phenomena.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a container for planting plants, which is a container of arbitrary shape and has a double structure, which is adapted for hydroponic cultivation.

Conventional technology Traditionally, this type of flower pot has a slightly conical shape when viewed from the cross section, and the inside is filled with soil, sand, etc., plants are placed there, and the pot is placed in the pot in the morning.
It is watered in the evening and kept for viewing.

Recently, planters that are rectangular when viewed from above are commonly used, and those with multiple holes on the bottom or with a net-like sana installed on the bottom to use the bottom as a water reservoir to allow water to fall. Some proposals have been made to release water from an opening in the container, but currently, soil is placed in a single-layer container and water is applied from above.

Problems to be Solved by the Invention In conventional containers for planting plants, soil is simply filled in a single container and watered from above to exchange air in the soil. There was a problem in that the deficiency caused root rot of plants.

This invention was proposed in view of the above circumstances.

Means for Solving the Problems Means for solving the problems described above will be explained using FIGS. 1 and 2, which correspond to embodiments.

The present invention is applicable to a container of any shape, for example, a conventional flower pot or planter 1, or a number of shapes such as circular and polygonal shapes. No restrictions shall be imposed in consideration of the above. The outer container (2) is made of plastic or ceramics, and has a plurality of projections (2) protruding from its inner wall surface. (2) is the inner container, and is preferably made of a lightweight synthetic resin fiber material or porous resin (porous sheet), but any material may be used as long as it is porous, absorbs water through capillary action, and does not corrode. Therefore, the inner container (2) may be formed into a flat plate so as to form a space (10) between the containers in accordance with the shape of the outer container (2), or it may be formed into a molded product from the beginning. In either case, the upper edge of the inner container (2) is brought into contact with the inner wall surface of the outer container (2). (2) is a ventilation hole, and a plurality of circular holes, vertical holes, horizontal holes, etc. are bored in the wall of the inner container (2);
Fill the inside with potting soil. ■ is the ventilation hole of the outer container ■, ■
is a water introduction hole, which is provided in the base of the outer container (2). (6)
1 is a drainage hole, and 2 is an insertion hole, which is bored in the bottom of the outer container (1) and a technical measure is taken to insert and remove the cut piece 2 at the lower end of the inner container (2).

When inserting an inner container ■ with a somewhat similar shape into a molded outer container ■, if the container ■ is originally circular,
By inserting the lower end cut piece ■ into the insertion hole ■ and fixing it, the double-structured container with a space formed between the outer container ■ and the inner container ■ is filled with cultivation soil and planted. Place the container in which the capillary roots have spread into the soil in an aquarium, place the bottom of the container on the lower ventilation hole of the container to the extent that the water level is maintained, and add water.
Liquid fertilizer and the like are circulated and supplied to the capillary roots of plants planted in the soil in the inner container to allow them to grow by capillary action.

Example Hereinafter, a description will be given based on one embodiment of the present invention.

■ is the outer container, which may be made of synthetic resin or ceramic, and may have a rectangular shape when viewed from the top, like a conventional conical flowerpot or buranter. Although any shape can be imagined, there is no limitation in any way as long as the shape is possible for plant growth. A plurality of protrusions are provided on the inner wall surface of the container (2). Reference numeral (2) denotes an inner container, which is formed to have a somewhat similar shape to the outer container (2), and has a large number of ventilation holes (3) perforated in its curved surface. The shape of the ventilation hole (2) is not limited to a circular shape, and may be a hole drilled vertically or horizontally.

(2) is a ventilation hole, which is perforated in the lower surface of the outer container, and a space (10') formed between the containers (2) and (2).
Inject air. ① indicates a water introduction hole, which is bored around the outer container ② stand. ■ is the drainage hole, and the outer container ■
drilled in the bottom of the (2) is a plurality of protrusions that protrude from the inner wall surface of the outer container (2).
2) Glue the outer periphery of the upper end to the inner wall surface of the outer container
10) is being gradually expanded. ■ is an insertion hole, which is bored in the bottom of the outer container (■), and its shape varies depending on the shape of the container; for example, if the bottom is circular, it will be a slight arc, and if it is rectangular, it will be a straight long groove. perforate. ■ is a cut piece at the lower end, which has a locking effect on the inner container (2
) is formed into a notched piece, which is inserted into the insertion hole (2) and fixed.

(U) is the bottom of the outer container ■, (12) is the inner container (2)
A drainage hole (13) is provided on the bottom surface of the hole (13).
Place it on the drainage hole (■) on the bottom of the outer container (■).

Therefore, each container (■) of the present invention has a double structure as shown in FIG. The container is placed in a water tank (16) with the water level maintained at the position of the lower ventilation hole, and a circulation device for water, liquid fertilizer, etc. is driven so that a part of the bottom of the container is immersed in the liquid level. Therefore, water, liquid fertilizer, etc. seeps into the soil in the container (2) through capillary action from the water guide hole (1) and the drainage hole (2) and grows.

Effects of the Invention As described above, this invention has a double-structured container, and a space is formed between each field container, and ventilation holes and drainage holes are provided, so that not only oxygen in the soil can be replenished, but also capillary action can be achieved. It is unique in that it automatically supplies water and liquid fertilizer appropriately, which saves labor in plant growth management, and also allows for the maintenance of the physiological environment of plants without uneven watering.
