JP-A-10-243737

  However, in the planter of patent document 1, artificial soil was directly piled up and filled on the upper surface of the bottom wall part. Therefore, the drainage of the artificial soil was poor, and the plants being cultivated were susceptible to root rot. In addition, since the bottom of the container is not partitioned, inconveniences such as tangling each other occur when cultivating a plurality of natural pods and yams. Furthermore, depending on the state of the plant being cultivated, it was not possible to supply a plurality of liquid fertilizers, chemicals, and the like to the artificial soil over the entire length of the container in an amount required when necessary. For this reason, there is a risk that the plant will be under-nutrition or various plant diseases will not be cured and will die.

  Moreover, at the time of the assembly of a plant cultivation apparatus, between the adjacent planters, the water supply pipes and drainage pipes which were arrange | positioned at each bottom wall part were mutually connected. For this reason, this connecting work is troublesome and time-consuming. And since two types of pipes are arranged on the bottom wall, there is a risk that the water supply pipe and the drainage pipe will accidentally communicate with each other, making it impossible to perform water management for all planters at once. It was.

According to the present invention, it is possible to secure a water channel over the entire length of the bottom of the container, thereby preventing root rot of the plant in the entire area of the container, and a plurality of liquid fertilizers and chemicals in a necessary amount when necessary. It aims at providing the cultivation container which can be individually supplied from the container bottom part with respect to the soil of full length.
In addition, the present invention is easy to change the design arrangement of the main body container, and is easy to assemble, and by simply communicating with the joint member, the water management for all the container main bodies can be reliably and collectively performed. It aims to provide a greening system that can be performed.

  According to the first aspect of the present invention, the bottom ends of a pair of side plates that are spaced apart in parallel are connected by a bottom plate, and both the end faces and the top face in the lengthwise direction are opened, and the length of the container body A pair of lid plates separate from the container main body, and a plurality of ribs having a height lower than the height of the side plate are provided in the width direction of the bottom plate. The cultivation containers are spaced apart from each other and project in the length direction of the bottom plate.

According to the first aspect of the present invention, the plurality of ribs having a height lower than the height of the side plate are separated from each other in the width direction of the bottom plate and protruded over the entire length of the bottom plate with respect to the upper surface of the bottom plate. For example, it is possible to secure a water channel over the entire length of the bottom of the container by laying a root-proof sheet (net) having water permeability on each rib and introducing soil. Thereby, even if the water supply to soil is excessive, the root rot of the plant is reduced throughout the container.
Moreover, if liquid fertilizer and chemicals are poured into the passages (liquid passages) between the ribs and the water in the passage is guided to the soil using a water supply cloth that penetrates the root-proof sheet, the entire length of the container body is reached. One or more types of liquid fertilizer and chemicals can be individually introduced into the soil from the bottom of the container body in the necessary amount when necessary. As a result, it is possible to prevent the plant being cultivated from becoming deficient in nutrition or from dying without various diseases being cured.

As a cultivation container, a planter etc. are mentioned, for example.
As a material for the container main body and the lid, for example, a hard and high strength synthetic resin such as vinyl chloride resin or ABS resin, wood, metal, or the like can be used. The shape of the container body is arbitrary as long as it is bowl-shaped. Although it is preferable that the height of both side plates is the same, the height may be different in the case of roof installation.
The container main body has a bowl shape, which means that the cross-sectional shape orthogonal to the length direction of the container main body is an upward substantially U-shape.
The number of ribs formed is arbitrary as long as it is two or more. The reason for the plurality is to improve the stability of the root-proof sheet when, for example, a root-proof sheet is laid on the rib. Non-woven fabrics, net cloths, wire nets, wooden nets, ceramic nets, and the like can be used as the root prevention sheet (net).
The height of the rib is arbitrary as long as it is lower than the height of the side plate.

The lid plate may be detachably provided at both end portions or one end portion in the length direction of the container body, or may be provided so as not to be separated.
Artificial soil is charged (deposited) into the container body. As the artificial soil, for example, non-woven fabric, polystyrene foam, polyethylene foam, perlite, wood chip, bamboo chip, foam glass and the like can be employed.
As a kind of plant to be cultivated, for example, a roof for a building is a plant having a low height such as lawn, clover, baby sunrose and the like. Verandas and windows are vines, natural selection, morning glory, bitter gourd, cucumber, and the like.
The container main body can be used by being arbitrarily connected in the length direction and the width direction, respectively.

  The invention according to claim 2 is the cultivation container according to claim 1, wherein the height of the rib is 10 to 50% of the height of the side plate.

  When the height of the rib is less than 10% of the height of the side plate, the frequency of operations such as water supply increases. Moreover, when it exceeds 50%, it will become easy to root rot. The preferred height of the rib is around 30% of the height of the side plate. If it is this range, both favorable workability | operativity and a root rot prevention effect will be acquired.

  According to the third aspect of the present invention, there are provided a plurality of bowl-shaped container bodies in which the lower end portions of a pair of side plates that are spaced apart in parallel are connected by a bottom plate, and both end surfaces and upper surfaces in the lengthwise direction are opened, and the container body A pair of lid plates that are separate from the container main body, closing the end surface in the length direction, and a joint member having a communication port and communicating the end portions in the length direction of the adjacent container main bodies. In the greening system, a plurality of ribs having a height lower than the height of the side plate are provided on the upper surface of the bottom plate so as to protrude over the entire length of the bottom plate while being separated from each other in the width direction of the bottom plate.

  According to the third aspect of the invention, for example, along the outer edge of the building roof, the end portions in the length direction of the adjacent container main bodies are sequentially connected to the plurality of container main bodies by the joint member. At this time, each joint member has a communication port. Therefore, the internal spaces of the connected container main bodies are in communication with each other via the communication port. As a result, a planting greening system can be deployed on the roof of the building. Thereby, the change of the design arrangement is easy and the assembling work is easy, and the water management for all the container main bodies can be surely performed collectively only by performing the communication work by the joint member.

As the material of the joint member, for example, the same material as the material of the container main body and the lid can be employed.
The shape of the joint member is arbitrary as long as it has a communication port and can communicate adjacent container bodies. For example, a plate shape or a frame shape may be used.
The connection angle of the container body by the joint member is arbitrary, for example, 90 °, 45 °. The connecting direction may be the length direction of the container body or the height direction. The number of connected container bodies is arbitrary as long as it is two or more.
As the shape of the communication port, for example, a circular, elliptical, triangular polygon or the like can be adopted. The size of the communication port is arbitrary. For example, it may be substantially the same as the lengthwise end surface of the container body, or may be smaller than that. One or a plurality of communication ports may be formed.

  The invention according to claim 4 is the greening system according to claim 3, wherein the height of the rib is 10 to 50% of the height of the side plate.

According to the first and third aspects of the invention, the plurality of ribs having a height lower than that of the side plate are spaced apart from each other in the width direction of the bottom plate and protruded over the entire length of the bottom plate. For example, if a root-proof sheet is laid on each rib and the soil is introduced, a water channel can be secured over the entire length of the bottom of the container. As a result, even if excess water is supplied to the soil, the root rot of the plant in the entire container can be reduced.
In addition, if liquid fertilizer and chemicals are poured into the passages between the ribs and the water in the passages is guided to the soil using a water supply cloth that penetrates the root-preventing sheet, it can be applied to the soil over the entire length of the container body. One or a plurality of types of liquid fertilizers and drugs can be individually introduced from the bottom of the container main body in a necessary amount when necessary. Thereby, the under-nutrition of the plant under cultivation and withering by various diseases can be prevented.

  In particular, according to the invention described in claim 3, when the end portions in the length direction of adjacent container main bodies are sequentially connected to each other by a joint member, the internal space of the container main body after the connection is established. They communicate with each other through a communication port of a hose or each joint member. Therefore, for example, a planting greening system can be deployed on the roof of a building. Thereby, the change of the design arrangement is easy and the assembling work is easy, and the water management for all the container main bodies can be surely performed collectively only by performing the communication work by the joint member.
