ることもできる。When peat moss is dried to a water content of about 30% or less, the water repellency becomes remarkable. Therefore, when peat moss is used as a material for compression molding, if it is dry, when it is expanded with water at the time of use after compression molding, the water is less likely to be absorbed and handling becomes inconvenient. Therefore, before compression molding, peat moss is mixed with bentonite or montmorillonite to attach fine particles of bentonite or montmorillonite to the surface of the peat moss fiber, and then compression-molded, the compressed peat moss is dried. Also easily absorb water, and the above problem is solved. In addition, bentonite or montmorillonite is a kind of clay component that can be extracted from natural materials, but if a chemical substance is used, an alkylene oxide-based or ester-based nonionic activator or the like is used as a water-repellent inhibitor. Can be used. In addition, peat moss generally has a pH
Since the pH is low at 3.5 to 5.5, slaked lime and quicklime,
Adjust the pH with formic lime, calcium carbonate, etc. In addition, slaked lime is preferable in terms of ease of handling and effects. By the way, the bentonite or montmorillonite also serves as a binder that acts as a binder when compression-molding peat moss, and enhances the binding effect during molding. Sodium alginate or the like can also be used as another binder.

めないよう、４５〜６０％の含水率のものが好ましい。Further, in order to increase the expansion ratio when the compression-molded culture medium 1 expands with water, a commercially available superabsorbent polymer or the like is mixed with a material containing plant fibers such as peat moss. Can also. For the compression molding of the above-mentioned material containing plant fiber, a press machine is used to pack the material (such as a mixture of peat moss and bentonite or montmorillonite fine particles) into the shallow box-shaped hole of the lower mold 2 and to form the upper mold. The rectangular plate-shaped projection 3 descends from above and performs compression molding (see FIG. 2). The compression pressure at this time varies depending on the water content of the material, but can be suitably compression molded by compressing at a pressure of 4 to 150 kg / cm 2 (4.5 kg / c when bentonite is mixed with peat moss from Canada).
When compressed at m 2 , the shape maintained after compression and the restoration speed and shape when water was included were good.) In the case of peat moss compression, the water content of the material to be compressed preferably has a water content of 45 to 60% so as not to damage the fiber.

It is supplied to the bottom of the compression molding medium 1 and the lower layer of the compression molding medium 1 is impregnated with fertilizer to obtain the compression molding medium 1 having a higher fertilizer concentration in the lower layer. In addition, when the specific dimensions are shown, the size of the compression molding medium 1 is 27.5 mm in length and 57.5 in width.
It is compression molded into a rectangular flat plate having a height of 5 mm and a height of 4 to 5 mm in a plan view.

First, as shown in FIG. 3, the compression-molded medium 1 is placed in the seedling box 5 with the fertilizer concentration being high (the mark or color is applied to the medium 1 after compression molding so that the fertilizer concentration can be immediately recognized). Or it is better to engrave a pattern that allows the upper and lower surfaces to be distinguished from each other at the time of compression molding), and pour water from above.

The expansion of the compression molding medium 1 ends in 3 to 5 seconds when tested. Then, the surface is flattened by a pressure-reducing device to make a uniform nursery bed, and the surface is uniformly seeded with paddy, covered with soil from above, and irrigated (FIG. 5).

水すると急速に膨張し、作業効率が良い。Next, the seedling box 5 after the seeding operation is put into a germination apparatus and germinated, and then seedlings are raised. The seeding operation is performed in this manner. Since the culture medium 1 is formed by compressing peat moss with fine particles of bentonite or montmorillonite attached thereto, it is light and not bulky. Can be supplied very easily, and the storage space can be small. Furthermore, the transportation cost of the light and non-bulky medium 1 is low and is excellent in industry. Since the medium 1 has fine particles of bentonite or montmorillonite attached to peat moss, it rapidly expands when irrigated, and the working efficiency is good.

肥料を得ることができて、良好なる苗の育成が行える。At the time of raising seedlings, since the main component of the mat-shaped seedbed 1 is peat moss, the water retention is good and the raising of seedlings is easy, and high quality seedlings can be easily raised. When carrying to a field for transplanting to a field, since it is lightweight, the work is very easy, not heavy labor like conventional soil. In particular, when the compression-molded medium 1 is reconstructed and seeded in the seedling box 5 and the soil is covered from above, the upper layer of the medium 1 has almost no fertilizer and can be germinated without fertilizer damage. The germination rate is good, and when the seedlings grow and the roots extend to the lower part of the culture medium 1, there is an appropriate fertilizer there, so that the seedlings can obtain fertilizer according to the growth, Good seedlings can be grown.
