  The present invention relates to a device for easily planting plants, flowers and other plants, particularly a planting device provided for cultivating plants on the rooftop or roof of a building, and a soil in this type of planting device. Is related to the water supply and drainage infrastructure.

In recent years, attempts have been actively made to plant plants on a large scale on the rooftops of buildings and other spaces, and to plant green spaces in urban areas.
In such a case, in many cases, a concrete layer of a presser foot is formed on a waterproof layer of a slab surface of a building or the like, and a gravel layer made of sand, gravel, etc. is used as a planting layer, Plants are planted by laminating layers one after another.

However, in order to obtain sufficient water retention and drainage for plants, it is necessary to introduce a considerable amount of earth and sand into the waterproof layer, and the concrete layer has a considerable weight, so these weights have an adverse effect on the building. There is a problem of affecting.
Therefore, the present applicant has previously disclosed a lightweight planting device excellent in water retention and drainage (see, for example, Japanese Patent No. 2531542).

In this planting device, a waterproof layer is fixed to a slab surface formed on the rooftop of a building, etc., and a water retention material having a nonwoven fabric or the like on the upper surface of the waterproof layer, and a drain plate having a concave portion and a convex portion 2 Water retention / drainage means composed of, etc., and a planting layer consisting of a gravel layer and a guest soil layer above the water retention / drainage means, and appropriate water retention / drainage by the water retention / drainage means etc. It has become something that can be obtained.
For this reason, the concrete layer provided in consideration of drainage becomes unnecessary, and the planting layer is set to a minimum necessary thickness considering the length of roots of plants and the like, for example, about 50 mm by improving water retention. It is possible.
The following documents are related to the present invention.
Japanese Patent No. 2531542 Japanese Patent No. 2717632

Therefore, in the conventional planting apparatus, the entire apparatus is reduced in weight and has an excellent function of avoiding adverse effects on buildings, but still includes some problems to be improved. .
That is, first, no countermeasure is taken against wind. This type of equipment is often installed in high places such as the rooftops of buildings, but in such high places there are always winds that are irregular in direction, so the soil of the guest soil layer is scattered. Cheap.
In addition, it is desirable to construct the soil layer as thin as possible from the viewpoint of the load on the building or the like, but if this is made too thin, the roots of the planted plant will not be stretched and will collapse even in a slight wind. This is particularly noticeable when planting a plant, and it is difficult to erect even when there is no wind in the case of a plant growing to a certain height.

In addition, in this type of equipment, once the soil layer is constructed, it is difficult to cultivate the soil in the soil layer, resulting in poor airflow below the soil layer, which has a significant impact on plant growth. It will be.
