Abstract

(57) [Summary] [Purpose] For planting seedlings that are made of biodegradable plastic to save the trouble of removing them from the container when planting the seedlings and to treat industrial waste, thus not causing environmental pollution. Get the container. [Constitution] A container configured as a pot 3 for accommodating the root portion of the sapling 1 and the soil 2 is formed of biodegradable plastic, and for example, planting of sand or rock slope 5 for revetment construction of roads or rivers. Applies to planting. The grid-like fences 6 which are arranged adjacent to each other in a staircase pattern on the slope 5 are covered with a biodegradable plastic sheet 7, and the pots 3 are embedded in the soil 8 accumulated between the fences 6 and left to grow as it is. When the seedling 1 grows and takes root, the biodegradable plastic pot 3 and the sheet 7 spontaneously decompose and return to the soil.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention provides a container for storing roots of planting seedlings and soil used for vegetation, tree planting, or slope greening for road or river bank protection work, and for placing such a container on the slope. It concerns a fence for greening slopes.

[0002]

[Prior art]

 Conventionally, as such a container, a small flower pot type container or a bag or bag formed of plastic material was used during transportation from nursery to planting on site, and the root part of planting seedlings and soil were cultivated. Was housed.

[0003]

[Problems to be solved by the device]

 However, conventional seedlings were taken out of these containers and planted on site at the time of planting, and the empty containers were treated as industrial waste. Therefore, there is a problem of environmental pollution when processing plastic containers.

Conventionally, as a method for planting and greening soil and rock slopes for revetment work on roads or rivers, as shown in FIG. 1, (a) a seed soil spraying method and (b) a transplanting method are used. , (C) cutting method, (d) pot method using concrete or wooden pots, (e) fence earth method, (f) stone masonry earth retaining method, (g) concrete wall earth retaining method.

These construction methods are used properly depending on the slope condition and have a long-term track record. Had problems such as dryness due to insufficient rainfall, and hindered root growth in the case of the pot construction method.

Therefore, an object of the present invention is to eliminate the trouble of taking out the seedling from the container when planting the seedling, and to obtain a container for planting seedlings which does not cause a problem of environmental pollution due to the treatment of industrial waste.

Further, an object of the present invention is to avoid the problem of seed, seedling, soil, etc. flowing out during slope planting and greening, or the problem of drying due to sunshine, and the problem of root growth inhibition in the pot construction method. To obtain containers for planting seedlings and fences for planting slopes.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the container for planting seedlings of the present invention is characterized in that the container is formed of biodegradable plastic.

Further, the slope-vegetation planting fence of the present invention is preferably characterized in that the fence is a wooden lattice fence and the fence is covered with a biodegradable plastic sheet.

[0010]

[Action]

 According to the container for planting seedlings of the present invention, the root portion of the planting seedlings and the soil for cultivation are stored and transported to the planting site during transportation until the planting at the site, and the plant and the soil are transported from the container at this site. Immediately embed the root part and soil with the container in the soil without removing it. By the time these seedlings are rooted in the soil at the site, the containers are disassembled and returned to the soil to ensure smooth and reliable planting.

[0011]

【Example】

 Next, preferred embodiments of the present invention will be described with reference to the drawings.

The container for planting seedlings according to the present invention shown in FIG. 2 shows an embodiment configured as a pot 3 for accommodating a root portion of a single seedling 1 and soil 2 for cultivation. The pot is formed by a biodegradable plastic.

The container for planting seedlings according to the present invention stores the root portion of the seedling 1 and the soil 2 and transports the seedlings to the planting site, without removing the seedlings from the container, The container 3 as it is is embedded in the loom 4 (see (b) of FIG. 2).

In another preferred embodiment of the present invention, an elongated groove pot 3A for accommodating the root portion of the seedlings 1 and the soil 2, which are made of biodegradable plastic and arranged in plural, is provided. It is also possible (see FIG. 3). When planting in areas with low rainfall, it is preferable to mix water-retaining materials such as water-absorbing polymer in pots 3 or 3A.

In another preferred embodiment of the present invention, the bag is formed of biodegradable plastic and is configured as a bag or a bag (not shown) for storing the root portion of the single seedling and the soil. You can also

FIG. 4 shows a construction method in which a container for planting seedlings according to the present invention is used for planting and greening soil or rock slopes 5 for revetment work on roads or rivers.

In the embodiment shown in FIG. 4, wooden lattice fences 6 are arranged in a staircase pattern along the slope 5. As shown in FIG. 5, the lattice fence 6 is covered with a sheet 7 formed of biodegradable plastic. Preferably, the crossbar 6a is fixed to cover the fence 6. The soil 8 is deposited between the lattice fences 6 adjacent to each other. In the case of planting in areas with low precipitation, it is preferable to mix water-retaining materials such as water-absorbing polymer in the soil 8. By covering the fence 6 with this sheet 7, it is possible to prevent the outflow of soil. Instead of a wooden lattice fence, a conventional futon basket made of metal wire can be used as the fence, and the futon basket can be covered with a biodegradable plastic sheet 7. However, wooden grid fences are suitable for greening close to the natural environment.

[0018] The seedlings 1 and the soil 2 stored in the container 3 or 3A in the form of a pot made of biodegradable plastic that has been transported from the nursery are placed on the soil 8 between the lattice fences 6 as they are, together with the slope 5 A plurality of them are embedded at appropriate intervals in the horizontal direction.

The bottom of the slope is reinforced by stone or concrete reinforcing surface 9 to retain the soil. From the viewpoint of protecting the natural environment, it is preferable that the reinforcing surface 9 is made of a stone made of porous stone.

In the example shown in FIG. 4, the seedlings are grown in the container 3 or the soil 2 in the container 3A, and when they are rooted in the site soil, the container is decomposed and returned to the soil, and the planting is continued. It is done smoothly and reliably. The container itself prevents outflow of soil and retains water. Further, the biodegradable plastic sheet 7 covering the lattice fence 6 also prevents the soil 8 from flowing out, and also has a water retaining function, so that it is possible to prevent drying due to sunshine. It is preferable to use the biodegradable plastic sheet 7 that is formed so that the seedlings are rooted in the soil and decomposed and returned to the soil when they can grow naturally as grown trees.

[0021]

[Effect of device]

 According to the present invention, it is possible to obtain the effects of saving the trouble of taking out the seedlings from the container when planting the seedlings, and of not worrying about causing environmental pollution.

Further, according to the present invention, it is possible to avoid the problem of seeds, seedlings, soil, etc. flowing out for planting and greening on slopes, the problem of drying due to sunshine, and the problem of root growth inhibition in the pot construction method. it can.
