Description of the Related Art Industrial wastewater, domestic wastewater, etc., which have been eutrophited with nitrogen and phosphorus, etc., flow into rivers and lakes to generate water-bloom and phytoplankton. Biotopes are formed by the breeding of cattails, flathead flounder, reeds, etc. to become water purification and habitat for natural flora and fauna. However,
Development is progressing for defense against natural disasters, vertical revetments, breakwater revetments, masonry revetments, levees, etc. have been constructed, and the shoreline form has been lost, reducing the number of wetlands inhabited by plants and animals. As a result, the number of wetland plants has decreased, and the polluted water that has been eutrophicationized with nitrogen and phosphorus in the inflowing effluent cannot be purified by self-cleaning action. As a result, there is a problem that spoilage due to water is increased and discharged as contaminated water, or sludge is deposited on the lake bottom. From the above, the importance of conservation of wetlands has been recognized, and in particular, Yoshihara, which has an excellent cleaning effect on domestic wastewater, has attracted attention.As a method of planting reeds, seeds are planted.
It is said that the method of planting seedlings and transplanting them by the large-plant transplantation method after raising the seedlings is effective for reed production.

ものである。However, it is said that the best breeding of reed communities is near the water level of 0 m, and it is extremely difficult to select a natural slope having an optimum hydrophilic soil. Moreover, even if the plants are vegetated, the seedlings are washed away by the waves, or they do not take root, so their implantation ability is not very good. In view of the above, the present invention provides a seedling-raising mat that provides a planting soil site that is optimal for the recovery of reeds and the like.

マットに関して以下に詳細に説明する。Since the mat for raising seedlings of the present invention is an excellent one having the above-mentioned conditions and is composed of a three-dimensional non-woven fabric, it can be easily handled during installation and mounting of piles, floats and the like. In addition, vegetation and water absorption and release, has a stable shape and water permeability to the load due to the growth of microorganisms,
Moreover, it can withstand waves and wind and rain. The mat for raising seedlings of the present invention will be described in detail below.

50d fine fibers (A component) and single fiber fineness of 300 to 10
It is necessary to be composed of thick fibers (component B) of 000d. The role of the component A is to obtain a net effect of retaining the seeds of the wetland plant on the mat and to effectively perform appropriate water / air replacement. If it is less than 5d, the fibers are too thin to make uniform mixing with the component B difficult.
If it exceeds, the number of fibers will decrease and the net effect will be impaired. The role of the component B is to form strength and appropriate voids, and is a major factor in determining the bulk specific gravity of the nonwoven fabric. If it is less than 300 d, the bulk specific gravity exceeds 0.1 and the voids become small, which is not preferable in terms of plant growth and the like. On the other hand, if it exceeds 10000 d, the bulk specific gravity exceeds 0.02 and the strength becomes too low, and it cannot be kept under various loads.

好ましい。The bulk specific gravity referred to in the present invention means a non-woven fabric sheet.
The value obtained by dividing the weight of the tongue by the apparent volume occupied by the weight. When the value is 0.02 to 0.1 g / cm 3 , a product excellent in strength, morphological stability and plant growth can be obtained. That is,
Since the bulk specific gravity is small, it is easy to replace air in the rhizosphere, and water is easily penetrated and dehydrated and dried, so that excellent plant growth can be exhibited. Further, in the case of such a bulk specific gravity, even a non-woven fabric having a thickness of 10 cm, a width of 2 m and a length of 10 m is as light as 4 to 200 kg and is excellent in handleability. The porosity is preferably 90 to 98%.
The porosity refers to the ratio of the volume of the actual fiber in 1 cm 3 . The thickness of the three-dimensional nonwoven fabric used in the present invention is preferably 3 to 30 cm, particularly 5 to 15 cm from the viewpoint of handleability and durability.

よい。The components A and B are preferably mixed in a ratio of 3: 7 to 7: 3. If the amount of the component A is too small, the sheet strength will decrease, and problems may occur in terms of shape stability and handleability. On the other hand, if the amount of B component is too small, the sheet strength is improved, but the bulk specific gravity is increased, and it may be unfavorable because proper penetration of water, air and fertilizer into the root zone of the wetland plant is hindered. Fibers other than the A component and the B component may be mixed within a range that does not impair the effects of the present invention. As the fibers constituting the mat of the present invention, any fibers such as natural fibers and synthetic fibers can be used, but synthetic fibers are preferable from the viewpoint of strength, durability and the like. Specific examples thereof include polyvinyl alcohol-based fibers, polyamide-based fibers, polyolefin-based fibers, polyester-based fibers and the like, and among these fibers, one or more kinds are more preferable.
In addition, polypropylene, polyethylene, polyvinyl chloride,
You may use the fiber which consists of polyester and its copolymer.

ましい。Polyvinyl alcohol fiber and polyamide fiber are preferable because of their high emissivity of far infrared rays. Particularly, polyvinyl alcohol fiber contains an OH group in its molecular structure and is sensitive to absorption and release of water. Therefore, it is more preferable.
In addition, since polyvinyl alcohol fiber has high hydrophilicity and the contact angle between water and fiber is very small, it has excellent adhesion to microorganisms in water (algae, protozoa, etc.), and can be disposed of after the marsh plant growth. Is also easy. Since wetland plants such as reeds are exhausted in a few years, the constructed mat must be removed from the shoreline coast and water, but polyvinyl alcohol fiber does not produce harmful gas even when incinerated, and the combustion heat Can be easily disposed of because it is similar to plant fiber. Further, since the mat is required to have high wave resistance and excellent weather resistance, a polyvinyl rucopolymer having high strength and excellent weather resistance in this respect as well.
Ru-based fibers are preferred. When using fibers having low weather resistance, it is preferable to add a black pigment or the like containing an ultraviolet deterioration inhibitor.

ことで容易に行うことができる。The method for producing the three-dimensional nonwoven fabric of the present invention is not particularly limited. For example, a method in which a thermoplastic polymer is discharged in a fibrous state and then melt-bonded to each other to form a continuous fiber into a non-woven fabric, or a monofilament is cut in advance to a cut length of 5 cm or more, and is rolled with a rope machine or the like. It is possible to adopt a method in which a rope is crimped in a pucker shape, the fibers are easily entangled with each other, and the fibers are fixed to each other with an adhesive such as an emulsion. The fibers can be easily mixed by discharging the thermoplastic polymer into a fibrous form (B component 300 to 10000 d) while crimping it, and dispersing the A component by pressure and mixing with air.
