Description

(4) The present invention relates to a vegetation mat capable of promoting plant growth in dry soil.

Generally, in plant cultivation, plants are grown by sowing plant seeds in the soil and applying water or fertilizer, but it is difficult to grow well on the ground where water or soil is easily washed away. In order to solve such a problem, there has been proposed a vegetation mat in which sheets containing seeds are stacked. The vegetation mat 1 includes a base layer 11 laid on the ground and a surface layer 12 provided on the base layer 11, as shown in FIG. A plurality of seeds 10 are interposed between them. Note that the figure shows the seed 10 in an enlarged manner for easy explanation.

As shown in FIGS. 4 and 3, the seed 10 of the plant germinates, a primary root 101 is generated, and after a while, the secondary root 102 comes out of the primary root 101, and the culm or stem is eventually removed from the surface layer 12. It grows out and grows to 103. By growing roots in the soil, the grown strains 103 have a water retention function and can stereotaxically germinate the seeds 10 and can be uniformly and greened to a large area.

However, when the vegetation mat 1 is spread on dry soil or a place with poor nutrition, the secondary roots 102 cannot readily absorb nutrients, so that plants cannot grow well and eventually die. There is still room for improvement.

The present invention has been made in view of the above problems, and provides a vegetation mat that contains nutrients required for initial plant growth, improves germination survival efficiency, and improves plant growth. The task is to

In order to solve the above problems, the vegetation mat of the present invention has a fiber base layer laid on the ground and a density thereof is smaller than that of the base layer, and the fiber base layer is overlaid on the base layer, and a fiber body, A fiber intermediate layer having a plurality of seeds scattered on the surface of the fiber main body and a plurality of nutrient bodies capable of providing necessary nutrients to the seeds by being contaminated in the fiber main body, It consists of a fiber surface layer provided on the fiber intermediate layer, and the density of the fiber base layer is larger than the fiber intermediate layer, so that the primary roots rooted from the seeds immediately penetrate into the base layer. Without extending, it is possible to temporarily extend into the fiber intermediate layer so that the primary roots and secondary roots rooted from the primary roots can absorb nutrients provided by the nutrients of the fiber intermediate layer. Is configured to

で は In this vegetation mat, it is preferable that the fiber base layer, the fiber intermediate layer, and the fiber surface layer are made of a material selected from a nonwoven fabric, a woven fabric, and a knitted fabric.

前 記 Further, it is preferable that the nutrient body is a mixture composed of cells selected from fungal species capable of promoting the growth of VA mycorrhizal fungi and other plants and peat soil.

Further, the fiber base layer has a layer thickness of about 1 mm to 3 mm, the fiber intermediate layer has a layer thickness of about 3 mm to 8 mm, and the fiber surface layer has a layer thickness of about 0.2 mm to 1.0 mm. Preferably, there is.

In the vegetation mat having the above configuration, the density of the fiber intermediate layer is smaller than that of the fiber base layer, so that the primary roots rooted from the seeds do not immediately penetrate into the base layer, but are temporarily stored in the fiber intermediate layer. So that the primary roots and the secondary roots rooted from the primary roots can absorb nutrients provided by nutrients scattered and dispersed in the fiber intermediate layer.

Other features and advantages of the present invention will become apparent from the following detailed description of the minimum embodiments, which proceeds with reference to the accompanying drawings.
The vegetation mat according to the embodiment of the present invention is, as shown in FIG. 1, a fiber base layer 3 laid on the ground, a fiber intermediate layer 4 laid on the fiber base layer 3, and a fiber intermediate layer 4 laid on the fiber intermediate layer 4. Fiber surface layer 5.

繊 維 Each of the fibers of each of the layers 3, 4, and 5 is made of artificial synthetic fiber, natural fiber or nylon fiber, and examples thereof include nonwoven fabric, woven fabric, knitted woven fabric, and other fiber materials. Hereinafter, the layer thickness of the fiber base layer 3 is about 2 mm, the layer thickness of the fiber intermediate layer 4 is about 5 mm, the layer thickness of the fiber surface layer 5 is about 0.5 mm, and each is a nonwoven fabric. I will explain with an example.

繊 維 The fiber base layer 3 is a layer to be laid on soil. The fiber intermediate layer 4 is overlaid on the upper surface of the fiber base layer 3, and has a layer density smaller than that of the fiber base layer 3. The fiber intermediate layer 4 is used to provide nutrients to the fiber main body 41, the plurality of seeds 42 supported on the fiber main body 41, and the roots coming out of the seeds 42 scattered in the fiber main body 41. Nutrient body 43 is provided. It should be noted that the seed 42 is illustrated in an enlarged manner for easy explanation. In the present embodiment, the nutrient 43 is preferably a mixture of bacterial cells, peat soil and organic fertilizer, and may contain only bacterial cells. Not exclusively. The bacterial cell is preferably a bacterial species capable of promoting the growth of a plant. For example, a powdery VA (Vesicular-Arbuscular) mycorrhizal fungus symbiotic with a plant root can be used. The nutrients 43 are scattered on the fiber main body 41 and are scattered in the main body 41 through gaps between the fibers. The fiber surface layer 5 is covered on the fiber intermediate layer 4 and is located at a predetermined position with the fiber body 41 and the seed 42 interposed therebetween. Also, the three-layer structure of the vegetation mat of the present invention can be formed by knitting, weaving, laminating or film coating.

Further, in the vegetation mat of the present embodiment, the nutrient 43 is formed in a structure similar to a fine thread-like net, thereby symbiotically infecting the secondary root 422 originating from the primary root 421 of the seed 42. Since the roots can be expanded, the effect of promoting the growth of the plant and enhancing the nutrient absorption function of the plant, as well as increasing the resistance to drying of the soil and disease can be obtained.

In addition, as shown in FIG. 2, by increasing the layer density of the fiber base layer 3 than that of the fiber intermediate layer 4, the primary roots 421 rooted from the seeds 42 can immediately penetrate the fiber intermediate layer 4. Instead, the secondary root 422 is rooted while being temporarily nested in the fiber intermediate layer 4, and then penetrates diagonally through the fiber intermediate layer 4 and the base layer 3 and enters the ground. Since the primary root 421 and the secondary root 422 are bred in the fiber intermediate layer 4 for a period of time, the nutrient 43, particularly the VA mycorrhizal fungus contained therein, causes nutrients and water to be lost. Since it can be efficiently absorbed, it is possible to reduce growth disorders such as poor rooting and early death of plants. Therefore, the vegetation mat of the present invention can be uniformly and greened even in a dry environment or poor soil.

As described above, the vegetation mat of the present invention has a structure in which the layer density of the fiber base layer is larger than the layer density of the fiber intermediate layer, so that the primary roots rooted from the plant seeds do not immediately penetrate into the fiber base layer. The secondary roots are taken out while being bred in the fiber middle layer, and water and nutrients provided by nutrients in the fiber middle layer can be absorbed, so that the growth of plants can be promoted and Even on land with poor environmental and soil conditions, it can be completely greened.

FIG. 4 is a cross-sectional view schematically illustrating a growth process of a plant seed in the vegetation mat of the present invention.
