DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening method using a tree seed bag suitable for greening a slope of a hillside with trees.

[0002]

2. Description of the Related Art For the purpose of protecting the above-mentioned slopes and restoring and preserving the landscape, for example, tree planting using native trees has been actively carried out. There are two types of tree planting: tree planting by transplanting seedlings and tree planting by seeding tree seeds.
Tree seeds are housed in a bag that is capable of germinating and growing tree seeds, and the tree seed bags are placed directly on slopes, etc., and fertilizers, soil improvement materials, organic materials, water retention materials, etc. A greening method is employed in which a suitably mixed vegetation base material is sprayed onto the tree seed bag. Alternatively, a method is known in which tree seeds are mixed with a vegetation base material, and the seeds are stored in a bag having a measure capable of germinating and growing the tree seeds, and the tree seed bags are placed on a slope or the like. .

[0003] In addition to this, a seed bag accommodating portion having an eye for enabling germination and growth of tree seeds is formed in a net stretched on a slope or the like, and the above-described tree seeds are accommodated in the seed bag accommodating portion. A vegetation base for greening was constructed by inserting a bag, and the vegetation base was stretched on a slope or the like, and a vegetation base material was sprayed as appropriate, or the above-mentioned vegetation base material was mixed with grass seeds, or a tree seed was attached. There is also a construction method that stretches vegetation mats on slopes.

[0004]

By the way, although not limited to tree seeds, seeds can withstand severe environments such as low temperature and dryness if they remain in a seed state. However, it is known that the seedlings that have germinated once are very weak, and whether or not the seedlings grow excellently greatly depends on the environment.

[0005] That is, the seeding period of tree seeds is generally 3
The optimal period is from Monday to June, July is a period in which only some trees can grow, and germination is from April to mid-November to February.
Since it is May, it is considered to be a viable period during this period, but when sown from August to early November, the seeds germinate in winter during or after the year, and the seedlings become cold in winter and frost heave. In spite of strong demands to plant seeds for tree planting throughout the year because they can not stand and die, in particular, greening works such as slopes are mainly public works, and trees are generally introduced. In spite of the relatively large number of sowing works in the fall season, which is considered impossible, sowing is currently being carried out while avoiding this period.

[0006] In view of such circumstances, an object of the present invention is to provide a greening method capable of sowing tree seeds throughout the year.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a tree seed bag 1 according to an embodiment of the present invention. The tree seed bag 1 contains a tree seed 3 in a bag 2 formed by a sheet that degrades over time, and a bag 2. Is sealed by means such as bonding.

As the sheet material of the bag body 2 which decomposes with time, for example, a photo-degradable or microbial-degradable plastic or a water-repellent or antibacterial-treated water-disintegrated paper is selected. Examples of the plastic include Polygrade (trade name, manufactured by Ambice, USA) and Plastigone (trade name, manufactured by Idea Masters, Inc.). Examples of the biodegradable plastic include bioleno (trade name, manufactured by Showa Kogyo Co., Ltd.) and Product name Tone (manufactured by AMKO, USA), product name Pullulan (manufactured by Hayashibara Co., Ltd.), product name Soa Phil (manufactured by Mitsubishi Rayon Co., Ltd.)
and so on.

When the water-repellent paper is subjected to a water-repellent treatment, means for immersing the water-repellent paper in a water-repellent agent or showering or spraying the water-repellent agent is used. Name Asahi Guard AG-710 and AG-7
A 3 to 5% solution such as 30 (all manufactured by Asahi Glass Co., Ltd.) is suitable, and a silicon-based, fluorine-based, or wax-based water repellent can also be suitably implemented.

Alternatively, an adhesive can be used for the water-repellent treatment. Examples of the adhesive used for this treatment include acrylic resin-based product name Polysol A-403-2 and A
A solution obtained by diluting T-130, other AP-6710 (all manufactured by Showa Polymer Co., Ltd.) or the like two to three times is preferable.

When an antibacterial treatment is applied to hydrolyzed paper, for example, lauryldimethylbenzylammonium chloride (Meirapit V-4 manufactured by Meisei Chemical Industry Co., Ltd.)
3), an antibacterial agent such as octadecyldimethylbenzylammonium chloride (trade name: Mekabinone SMB-85, manufactured by the company) is effectively used.

Among various antibacterial agents, those containing dimethylbenzylammonium chloride as an active ingredient, for example, the above-mentioned lauryldimethylbenzylammonium chloride and octadecyldimethylbenzylammonium chloride have a good effect of inhibiting corrosion of hydrolyzed paper by microorganisms such as bacteria. Thus, decomposition can be effectively suppressed for a certain period of time, and thereafter, the corrosion inhibitory effect is lost and the water-disintegrated paper is homogenized with soil, which is suitable for environmental greening.

The decomposition rate of these decomposable plastic sheets or water-repellent or antibacterial water-decomposed papers varies depending on the composition, thickness, environment and the like, but is preferably 4 or more.
Select one that decomposes in months to five months.

The tree seeds 3 to be stored in the bag 2 include Yamahagi, Itagigi, Yamahanoki, Yashabushi, Storm, Mozumimochi, Akamatsu, Yamahagi, Komatsunagi,
There may be used shrimp, squab, sharinbai, etc., and one or more of these are appropriately selected and used.

In the above-described tree seed bag 1, only the tree seeds 3 are stored in the bag body 2. FIG. 2 shows a tree seed bag 1 instead of this configuration. In this example, tree seed 3
Is mixed with a vegetation base material 4 composed of at least one of a slow-acting or slow-acting fertilizer, a soil conditioner, an organic material, and a water retention material, to form a bag 2 formed of a sheet that decomposes over time. It is characterized in that it is housed and the mouth of the bag 2 is sealed by means such as bonding. In addition, as the organic material, one or more types such as bark compost and peat moss are selected, and as the water retention material, one or more types such as a superabsorbent polymer, vermiculite, and partlite are selected.

The greening of the slope or the like by the tree seed bag 1 including the vegetation base material 4 is the same for the tree seed bag 1 containing only the tree seeds 3 not including the vegetation base material 4 shown in FIG. However, as shown in FIG. 3, for example, the tree seed bag 1 is directly installed on the slope 5 and an anchor pin 6 is driven into the slope 5 to fix the position. This is performed by spraying a vegetation material 7 appropriately mixed with a material, an organic material, a water retention material, and the like.
When a photo-decomposable plastic sheet is selected as the material, it is important to prevent the vegetation material 7 to be sprayed as necessary from covering the tree seed bag 1 and expose the bag body 2 to sunlight. .

Even if the tree seed bag 1 is placed on the slope 5 as described above, the bag 2 does not disassemble until four to five months have elapsed. The tree seeds 3 housed in the container are maintained in a state of seeds, and can withstand a severe environment such as low temperature and drying. And 4
When the bag body 2 starts to be decomposed after 5 to 5 months, the vegetation base material 4 contains rainwater, the tree seeds 3 absorb water, and the tree seeds 3 germinate. After a period of 4 to 5 months, the seeded state appears for the first time.

In other words, germination is adjusted artificially over a period of 4 to 5 months even after the seeding is completed, and therefore, the seeding is considered to be an unsuitable period for sowing.
If the above-mentioned tree seed bag 1 is constructed from Monday to early November, the tree seeds 3 are germinated in winter and the seedlings die out due to low temperature. It can germinate, and eventually the protection of the slopes and the like, the restoration of the landscape, and the afforestation of the preservation are achieved, and the tree seed bag 1 of such a configuration and the so-called tree seed bag 1 have been used so far. By selecting a tree seed bag that does not have a function of controlling corrosion decomposition, tree seeds can be constantly sowed throughout the year without being restricted by the sowing period.

Next, with respect to the tree seed bag 1 including the vegetation base material 4 shown in FIG. 2, a number of greening vegetation substrates provided with the tree seed bag 1 will be described. First, a vegetation base 8 for greening shown in FIG. 4 is provided. The vegetation base 8 is provided on a net 9 stretched on a slope or the like, in a seed bag receiving section having an eye for germinating and growing the tree seeds 3. The present embodiment is characterized in that the tree seed bags 1 are inserted into the seed bag accommodating section 10 while forming the tree seed bags 10 at predetermined intervals.

According to the vegetation substrate 8 having such a configuration, the tree seed bag 1 on which germination has been adjusted is widely spread at a predetermined interval by stretching the vegetation substrate 8 on a slope or the like. It can be constructed, and the tree seeds 3 are stored in the bag body 2 and inserted into the seed bag storage part 10, so that the runoff is reliably prevented, so that the young seedlings of the tree can be sloped in early spring. It grows in a tidy and zonal fashion, and eventually the protection of the slopes, the restoration of the landscape, and the maintenance of forests are achieved.

The vegetation base 8 for greening shown in FIG. 5 is attached to a net 9 which is stretched on a slope or the like, and the tree seed bag 1 shown in FIG.
And a bag 12 accommodating a vegetation base material 11 composed of at least one of fertilizer, soil improvement material, organic material and water retention material and pasture seeds. More specifically, a net 9 provided on a slope or the like is provided with a seed bag storage unit 10 having a seed capable of germinating and growing tree seeds 3 and a base having a seed capable of germinating and growing grass seeds. The material bag accommodating portions 13 and the bag accommodating portions 10 are alternately formed at predetermined intervals, and the tree seed bags 1 and the vegetation base material accommodating bags 12 are placed in the respective bag accommodating portions 9 and 13. It consists of inserting.

The greening of the slope 5 with the greening vegetation base 8 is performed, for example, as shown in FIG. 6A by stretching the greening vegetation base 8 on the slope 5 and fixing the position. An anchor pin 6 is driven into the slope 5 and a vegetation material 7 appropriately mixed with fertilizer, soil improvement material, organic material, water retention material and the like is sprayed as needed. At this time, if a photodegradable plastic sheet is selected as the material of the bag body 2 that decomposes over time, it is necessary to prevent the vegetation material 7 sprayed as necessary from covering the tree seed bag 1 as described. It is.

When water is sprayed on the vegetation material 7 or when the vegetation material 7 is in rain, the grass seeds absorb moisture and germinate, and as shown in FIG. Grass grows in a belt form on 7 layers of material,
Early greening is carried out. However, the tree seed 3 in the tree seed bag 1 keeps its seed state until the bag body 2 is decomposed with time, and overwinters in a severe environment such as low temperature and drying.

After the greening vegetation substrate 8 is stretched,
After a lapse of months to five months, the bag body 2 starts to be decomposed as shown in FIG. 3C, the tree seeds 3 in the tree seed bag 1 absorb water, and germinate, and FIG. As shown in (1), the tree seeds 3 germinate between the belt-shaped pasture rows in early spring to become young seedlings. Since the seedlings are separated from the pasture, they grow without being pressed by the pastures, and the slope 5 is eventually turned into a forest, and the protection of the slope 5 and the restoration and maintenance of the landscape are achieved. is there.

The greening vegetation substrate 8 shown in FIG. 7 has, in addition to the structure of the greening vegetation substrate 8 shown in FIG. The present invention is characterized in that a mat 14 capable of germinating and growing the tree seeds 3 is provided, and in this embodiment, the mat 14
A vegetation material 15 composed of one or more of plant seeds such as grasses, wild grasses, and flowers, fertilizers, soil improvement materials, organic materials, and water retention materials is adhered to the net 9 side, but installation of the vegetation material 15 is omitted. It can be implemented.

According to the greening vegetation substrate 8 having such a structure,
In addition to achieving the same slope greening as the greening vegetation substrate 8 shown in FIG.
Erosion of the surface layer is effectively prevented, and when plant seeds are selected as the vegetation material 15, pasture, wild grass,
When the slope 5 is greened by at least one kind of flower or the like, and particularly when grass seeds are selected, the tree seedlings may be pressed by the strong grass, which indicates that the mat 1
4 effectively prevents it.

The vegetation substrate 8 for greening shown in FIG. 8 includes a fertilizer, a soil conditioner, an organic material, and a material between an upper sheet 16 and a lower sheet 17 made of at least partially decomposable material.
The vegetation base material 18 composed of one or more water retention materials and the tree seed bag 1 having the configuration shown in FIG. 2 are interposed, and the germination and growth of the tree seeds 3 are provided on the outer surface of the upper sheet 16. It is characterized in that a net 19 is provided.

In this embodiment, the upper and lower sheets 1
Between 6,17, super absorbent polymer and vermiculite,
A bag 20 containing a water retention material such as a part light is interposed to continuously distribute and supply water and improve the fertilizing effect. Instead of this water retention material, pasture, wild grass, flowers, and the like are used. Plant seeds or fertilizer, or a mixture of fertilizer and a water retention material. When storing plant seeds, as a bag material, for example, Bonric (Vensei Paper) It is desirable to use a water-absorbing corrosive material capable of germinating and growing plant seeds, such as that manufactured by Co., Ltd., but this can be carried out without the bag 20 interposed.

According to the greening vegetation substrate 8 having such a structure,
In addition to achieving the same slope greening as the greening vegetation substrate 8 shown in FIG. 5, the upper and lower sheets 16 and 17 are made of a decomposable material, so that the entire vegetation substrate 8 is made flexible. When the vegetation base 8 is stretched on the slope, there is no partial lifting, and the vegetation base 8 fits well with the slope 5 and adheres well. Well done. Moreover, the top sheet 16
Since the net 19 is provided in advance on the outer surface side, the labor of the net construction at the site can be omitted, and the construction cost of the greening work can be reduced accordingly.
