Description

  The present invention relates to a plant cultivation carrier.

  Solving the urban heat island phenomenon is very important for reducing peak power in summer and preventing global warming in recent years.

  As a means to solve the heat island phenomenon in urban areas, for example, plants are propagated on the rooftops and walls of buildings such as buildings, and the sunlight directly irradiated to the buildings by the plants is weakened to lower the building surface temperature. That (greening of building walls, etc.) is useful.

  When planting a wall of a building or the like, it is common to cultivate a plant of the same type and propagate it so that it hangs around the building. However, there is a problem that it is difficult to propagate evenly around the building, and maintenance such as normal care and removal when the plant withered is very difficult.

  On the other hand, for example, Patent Document 1 below discloses a wall surface greening device that includes a vegetation mat including a vegetation substrate soil and includes a vegetation substrate body using a lattice-shaped net sheet.

  Further, for example, the following Non-Patent Document 1 discloses a vegetation net with a fertilizer bag.

  However, the technique described in Patent Document 1 uses a vegetation mat, and the limit of the height of plant growth becomes the limit of the height of greening, which makes it extremely difficult to apply to buildings with a certain height. There is a problem.

  Note that the vegetation net described in Non-Patent Document 1 is based on the premise that fertilizers and the like are melted from the soil fertilizer bag to the soil surface by water and the like, and the plant grows in the soil. The limit of the height of planting is the limit of greening height.

  Therefore, in view of the above problems, the present invention provides a plant cultivation carrier that can be easily propagated evenly around a building and can be easily maintained during normal maintenance and removal when a plant withers. The purpose is to do.

  That is, the plant cultivation carrier concerning the 1st viewpoint for solving the above-mentioned subject is the core member containing a fertilizer element, the 1st gel layer arranged around this core member, and this 1st gel layer One of the features is that it has a second gel layer including seeds and a rope layer disposed around the second gel layer.

  As described above, according to the present invention, it is possible to provide a plant cultivation carrier that can be easily propagated evenly around a building, and can be easily maintained such as normal maintenance and removal when a plant withers.

The material of the core material 2 is preferably a substance that is hard enough to hold the first gel layer 3 and the second gel layer 4 around it, and when a material with many voids is used, More preferably, the voids can be impregnated with fertilizing elements. Although it does not necessarily limit as this material, For example, it is a preferable example that it is a plant fiber support which consists of plant fibers, such as a bamboo fiber and rice straw. In addition, the diameter of the core material 2 is not particularly limited, but when the diameter of the second gel layer 4 is 1, it is preferably in the range of 0.02 to 0.1.

  Moreover, in this embodiment, the fertilization element contained in the core material 2 ensures the growth of a plant, for example, a high-concentration liquid fertilizer, a powdered fertilizer, a residue after producing a fermentation product such as biomass ethanol Although it can illustrate, it is not limited to this. The core material holding the fertilizer element can be produced by preparing an aqueous solution containing the fertilizer element and immersing the core material before treatment.

  In the present embodiment, the first gel layer 3 is a layer made of a gel-like substance disposed around the core material 2. By using a gel-like layer, the plant cultivation carrier can contain a large amount of moisture and can diffuse fertilizing elements eluted from the core material 2, and the plant cultivation carrier has a certain shape. Can keep.

  In the present embodiment, it is preferable that the first gel layer 3 has a lower diffusibility of the liquid impregnated than the second gel layer 4. By doing in this way, it can adjust so that the rate of elution of the fertilization element from the core material 2 may become slow, and it becomes easy to prevent drying of a core material.

  The material for the first gel layer 3 is not limited, and for example, hemicellulose, mucopolysaccharide, and collagen can be employed. In the case of hemicellulose, xylan, mannan, glucomannan, glucuronoxylan and the like can be exemplified.

  The diameter of the first gel layer 3 (including the core material 2) is not limited, but when the diameter of the second gel layer 4 is 1, it is 0.05 or more and 0.2 or less. It is preferable that it is the range of these.

  Moreover, in this embodiment, the 2nd gel layer 4 is a layer which consists of a gel-like substance arrange | positioned around the 1st gel layer 4, and is impregnated rather than the 1st gel layer 3 as above-mentioned. It is preferable that the liquid has high diffusibility. By doing in this way, it can adjust so that the speed | rate of elution of the fertilization element from the core material 2 may become slow.
