Description

[Detailed Description of the Invention] [Industrial field of application] This invention is used for soil-cultivated vegetative plants such as turf, clover and spinach, which are cultivated in a flat manner and used for viewing. The present invention relates to a plant cultivation mat for walking on a lawn or lying on the grass and enjoying the feeling.

[Problems to be solved by conventional techniques and devices]

Flowering plants and foliage plants are commonly used as plants to be planted while cultivating indoors or on balconies, and these plants are cultivated while being soil-planted in flowerpots or small flower beds while watering. Further, in recent years, an artificial solid medium consisting of a gel-like substance that retains a large amount of water in itself is stored in a container, and the root of the plant is buried and held in the medium in the container, while cultivating without soil. It is also practiced to enjoy plants as a kind of upholstery.

By the way, it has not been conventionally practiced to cultivate dense plants that grow densely on a plane, such as turf, indoors or on a veranda. This requires a relatively large amount of soil because such a dense plant is meaningless unless it is cultivated on a certain wide flat surface, but it is difficult to obtain, especially in urban areas, and transportation is troublesome. In addition, it is difficult to bring it into the room because there is a risk of soil spilling and soiling the floor, etc. It is difficult to handle the soil, and the field scene must always be on a horizontal surface. Of 1
Poor variability when viewed as one, when using an artificial solid medium, since the artificial solid medium is formed by a gel material that is very soft and brittle, even when turf is cultivated, normal You can't ride on it or walk on it like you can on the lawn, but it's not interesting to just watch it, and there are problems with drainage associated with irrigation. is there.

Therefore, this device can cultivate vegetative plants such as grass without using soil, and therefore can cultivate vegetative plants indoors or on the veranda, which is highly variable and exerts an interior decoration effect. It is also an object of the present invention to provide a mat for vegetative plant cultivation that can be walked on or laid on it in the same manner as a normal lawn when turf is cultivated. . Another object of the present invention is to provide a vegetative plant mat that allows vegetative plants to be cultivated more easily indoors without the need for irrigation.

[Means for Solving the Problems]

In this invention, as means for achieving the above-mentioned problems,
A large number of filament elements made of synthetic resin and having a diameter of 0.5 to 2.0 mm are three-dimensionally intertwined and the contact points of these filament elements are fused or adhered to each other, and the porosity is 75 to 90%, A mat for vegetative plant cultivation was formed by forming a medium construct by molding into a flat plate having treading and deformation recovery properties, and enclosing the lower face and the peripheral side faces of the medium construct in a watertight manner with a waterproof material. Use as a summary.

The above-mentioned culture medium construct may be coated with a sheet on the upper surface thereof, and the gel-like water retaining material may be loaded in the voids in the culture medium construct. Also,
A mat for vegetative plant cultivation may be formed by integrally joining a waterproof sheet to the lower surface of the medium construct and surrounding the peripheral side of the integral body with a frame in a watertight manner.

[Action]

In the mat for vegetative plant cultivation of the above configuration, a large number of filament elements are entwined three-dimensionally and water is retained in the portion of the medium constituting body in which the contact portions of these filament elements are joined, and the medium composition The vegetative plants grow rooted in the voids between the streak elements of the body, and the leaf stems are two-dimensionally spread in a dense state on the upper surface of the plate-shaped medium construct to form a plane of the vegetative plants. Further, since the lower surface and the peripheral side surface of the culture medium construct are watertightly surrounded by the waterproof material, water leakage from the mat does not occur. Further, since the porosity of the medium construct is 75 to 90%, the air circulation is good inside and the root rot does not occur. In addition, since the culture medium construct has resistance to trampling and deformation recovery, even if a person rides on it, the surface does not greatly dent, and the water emerges on the top face of the culture medium construct. In addition to that, even if the surface is slightly recessed, the original state is promptly restored when the load is removed.

Further, when the upper surface of the medium construct is covered with a sheet body such as a non-woven fabric or a synthetic resin film, excessive water evaporation from the medium construct can be suppressed when irrigating. Further, by allowing the seeds of the vegetative plant to be mixed in the sheet-shaped body such as the nonwoven fabric, the vegetative plant can be grown from the seed state.

Further, when the gel-like water retaining material is loaded in the voids in the medium construct, it is not necessary to irrigate, and problems such as drainage are solved.
