DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass substrate for greening, and more particularly, to a plant base for plant cultivation which can perform healthy greening for a long period of time even on steep slopes or places where water retention is not expected and which is excellent in decoration. It relates to a glass substrate for greening.

[0002]

2. Description of the Related Art As a method of greening a vertical surface or a steep slope such as a wall surface, a net-like object is attached to the surface of the vertical surface or the slope, and a climbing plant is put on the net-like material. The plant is planted on the surface and the plant is artificially put on the surface. This method has a problem that the types of plants used are limited.

As a method of greening a slope called a slope, a method of spraying a thick base material in which a soil containing plant seeds and fertilizer is directly sprayed on the slope is generally used. In order to prevent fertilizer soil or peat moss, solidify it into a disc shape, enclose plant seeds in it, or perform greening using fertilized soil and plant seeds sealed in bags, continuous voids Using porous green concrete filled with clay, fertilizer, plant seeds and the like in the voids (Japanese Patent Publication No. 58-58)
No. 10535, JP-A-53-114204), a method in which an organic solid is mixed with an aggregate and bound with a binder, and a method in which the organic solid is embedded in the porous concrete have been proposed (Japanese Patent Laid-Open No. Hei 4 (1994)). -89919,
Nos. 4-89920 and 4-89921).

According to the above-mentioned method, for example, in the thick layer base material spraying method, on a steep slope, the soil is eroded by rainwater or freezing, and the thick layer base material flows out, so that permanent greening is difficult. Even if a base material in the form of a bag or a bag is used, the durability is improved compared to the spraying method, but the durability is insufficient.The method using greening base concrete makes it difficult to fill a sufficient water retention material. Furthermore, even if the water retention material is sufficient, there is a problem that the growth of plants is inhibited by elution of ions from concrete. In addition, the method of mixing an organic solid with an aggregate and binding with a binder has a problem that it is difficult to select the type and the amount of the aggregate and the binder for obtaining a sufficient void.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to realize permanent greening even on a vertical surface or a steep slope by using it as a greening base, without inhibiting plant growth. It is possible to provide a glass substrate for greening that can be used irrespective of the type of plant and is also preferable in appearance, and furthermore, by a simple manufacturing method, can be filled with an arbitrary amount of a water retention material. .

[0009]

The glass substrate for greening of the present invention uses a glass having a relatively low melting point as an inorganic substance as a base material, so that a base material having arbitrary voids can be easily obtained, and components eluted from the glass. It does not inhibit plant growth. Further, by producing the glass substrate by surface fusion of glass particles such as glass cullet, it is possible to obtain a greening glass substrate by an inexpensive and simple method. In addition, by using inorganic particles having a melting point higher than that of glass as a water retaining material to be filled, an arbitrary amount of glass particles and a water retaining material are incorporated at the time of producing a greening glass substrate, and then heated and fired to reduce the glass particles. By fusing the surfaces, a greening glass substrate filled with an arbitrary amount of a water retention material can be integrally and simply manufactured.

In the present invention, the continuous space refers to a space through which free water and air can flow. The porosity of the greening glass substrate needs to be 20% by volume or more from the viewpoint of plant root growth and respiration, but the durability of the greening glass substrate,
It goes without saying that the upper limit is limited by the type of glass used in terms of strength. In addition, a preferable range of the area of the opening on the surface of the green glass substrate can be selected depending on the angle of the slope. It is preferable to reduce the opening area as the slope approaches vertical, but by controlling the shape of the opening and the shape of the side wall of the opening, the greening glass substrate with a wide opening area can be formed on a vertical surface or an extremely steep slope. It can also be used.

The water-retaining material used in the present invention is not particularly limited as long as it has physical properties and water-retaining property suitable for growing a plant. Specific examples include fertilizer soil, peat moss, black soil, commonly used soils such as perlite, Kanuma soil and other general soil particles, and porous and water-retaining inorganic porous materials such as fired shale. Body, polystyrene,
Deformable organic porous materials such as polyethylene or polypropylene sponges, polyurethane foams, sponges, etc .; water-absorbing polymers such as cross-linked polyacrylic acid and cross-linked polyvinyl alcohol; These may be used in combination, or may be used by mixing them with a chemical fertilizer.

In the present invention, the glass particles include all solid particles of glass, and the shape may be spherical, rod-shaped, or even amorphous such as crushed glass. Good. The size of the glass particles is arbitrary within a range in which a preferable continuous void can be obtained. For example, a size of about 5 to 100 mm is preferable. If it is less than about 5 mm, it is difficult to obtain a preferable continuous void.

When a glass having continuous voids is formed by fusing glass particles on the surface, a glass substrate for greening can be manufactured from inexpensive raw materials by using glass cullet, which is a waste glass material, as the glass particles. In addition, the use of waste is environmentally preferable.
