[Conventional technology] Hydroponic cultivation of plants has traditionally been done using the phlegm type, fl! Various methods such as exhaust circulation type and bottom flow circulation type are being implemented. Both of these methods involve soaking the roots of the plant in a nutrient solution;
As for supporting the plant body, it is most common to hold the plant stem with a urethane foam block fitted to a panel or the like placed above the nutrient solution. In order to support the plant in this case, seeds are sown in the urethane foam block, germinated, and the roots that have grown through the urethane foam block are planted in a hydroponic cultivation device, and the plant is placed on the device. It is fixed at

[Problems to be Solved by the Invention] As mentioned above, urethane foam blocks have been most commonly used as supports for conventional hydroponic cultivation, but these urethane foam blocks have the following characteristics. It should be solved
! I had an issue. That is, the conventionally used urethane foam blocks had a problem in that the tensile strength and tear strength of the resin film constituting the foam voids were too high, which hindered the growth of plant roots. Furthermore, in order for the sown seeds to germinate, the support must have an appropriate water retention capacity, so it was necessary to reduce the size of the bubbles in order to obtain capillary action. However, this resulted in a situation where root elongation was further inhibited. As a result, this did not pose much of a problem when growing plants with relatively thin roots, but it was not possible to germinate and grow plants with thick roots, such as spinach, on urethane foam. . Hereinafter, in the present invention, the ease of root elongation will be referred to as rootability.

The object of the present invention is to provide a cultivation support and an optimal method for germinating plants and promoting their subsequent growth.

[Function] The present invention is constructed as described above, but in short, fibers whose maximum cross-sectional diameters fall within a specific range are bundled in parallel and have bulk specific gravity within a specific range, which exhibits good water absorption and water retention properties. This is because it has been found that the fibers exhibit good performance and have good rooting properties, making it easy for roots to grow along the fiber bundles. In other words, the aim is to maximize the capillary phenomenon in which water rises against gravity and the space provided for roots to grow by utilizing the fine voids created by the fiber bundles.

The fiber used in the present invention is natural 1! fiber, chemical fiber 1
Synthetic fibers, ceramic fibers, metal fibers, etc., or even resin-processed fibers of these fibers may be used, but are not limited in any way, and the maximum diameter of the cross section is 10 to 10
It is necessary that the thickness is 0 μm. That is, when the maximum diameter of the fibers is less than 10 μm, the density when bundled becomes too large, resulting in poor water retention and root threadability. On the other hand, if the maximum diameter of the fibers exceeds 100 μm, the bundle becomes a rough and hard block shape when bundled, resulting in poor water retention and rooting properties (IA fibers are thicker and have greater bending elasticity, which increases root elongation. (This makes it difficult for the roots to spread out.) The preferred range of the maximum diameter of the fibers is about 15 to 50 μm. In addition, the maximum diameter mentioned above means the diameter of the major diameter part when the cross-sectional shape perpendicular to the axis is elliptical, and when the cross-sectional shape perpendicular to the axis is irregular, it means the diameter of the longest part, and furthermore, the maximum diameter in the longitudinal direction. - In the case of fibers with different diameters, it means the diameter of the thickest part.

The fibers used in the present invention may be short fibers or long fibers, but in either case, they are aligned in the longitudinal direction of the fibers and bundled in a parallel state. Here, the parallel state means a state in which the fiber bundles can be easily peeled off along the longitudinal direction.

The method for maintaining the shape of the focused fiber bundle is not limited in any way; for example, the outer periphery of the fiber bundle may be bound with a string-like material or tape-like material; Although a tape-like material may be coated spirally, the following embodiment is most preferred. That is, low melting point fibers having a melting point difference of 20° C. or more from the main fibers or sheath core structure fibers having a low melting point only on the surface are mixed and bundled, and the outer periphery of the fiber bundle is heated to mainly weld and shape maintain the outer periphery. This is advantageous because a focused body with a stable shape can be obtained.

.. If the bulk specific gravity is less than 0.05 g/cm3, it will be too coarse and have poor water absorption and water retention properties, and if the bulk specific gravity is more than 0.15 g/cm', it will be too dense and have poor rootability. A preferable range of the bulk specific gravity of the bundle is about 0101 to 0.07 g/cm'.

The shape of the bundle may be cylindrical or polygonal and is not limited in any way, but when used, it can be divided by a surface perpendicular to the longitudinal direction or an inclined surface (preferably a surface at right angles) to form an appropriate shape. Need to adjust the length. The length varies depending on the length of the fitting part of the hydroponic cultivation device and the growing plant, but is preferably about 10 to 30 mm.
