DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for growing woody trees using a special mulch in slope greening and a method for growing the woody trees, and a bag containing seeds of a woody plant laid on the slope. The growth environment of herbaceous and woody plants is improved by simply constructing and covering a special mat-shaped mulch on the surface of the growth base layer with seeds mixed after spraying on the slopes. The purpose of this project is to revegetate a slope that enables the formation of a communal community, and to reliably protect the growth base from heavy rain, strong winds, frost heaves and drought disasters.

[0002]

2. Description of the Related Art In general, early greening for the purpose of preventing erosion of a slope has been given priority to ground covering mainly by herbaceous plants. In recent years, a tree planting method that simultaneously introduces woody plants to enhance harmony with the surrounding environment and strengthens the stability function by elongation in the root soil is desired, and slope greening mainly using woody plants is being implemented. .

[0003]

However, depending on the construction time, the growth of the woody plants is not good and the growth base and the ground are eroded, or with the growth of the woody plants, the ground seedlings sown at the same time gradually decline. This leads to the formation of a stand alone of trees, resulting in the phenomenon that the growth base and the ground surface become thin. In addition, conventional simultaneous seeding (mixing) of herbs and trees results in formation of a single community. That is, in the first case, when the herb is mainly used, the slow-growing woody trees are under pressure and cannot be established (herbaceous single community). Part 2
When a tree is mainly used, herbaceous undergrowth is oppressed and declines (single community). Third, if the construction time is not favorable, it is difficult to grow woody species (slopes with sparse vegetation).

[0004] Next, with regard to the growth base, the applicant of the present invention has been conducting research and development for improving the slope greening method for many years. As a result, the production of recycled greenery bases (Patent Nos. 2062221, 2542525, and 20006
No. 11 and Patent No. 1762172 were provided. In addition, the applicant has developed a recycle greening method called PMC method. The content is as follows. The mortar spraying machine puts the soil (= growth base material), which is a mixture of pied wood (= registered trademark, designated product: flying powder fertilizer) and coating fertilizer, into the greening base material. It is conveyed by compressed air and sprayed to the slope with a predetermined thickness while mixing with water when spraying the nozzle at the tip of the spray hose. After that, the seeds and
Attach a net with curing material. In other words, by combining seeds with the net body for protecting the growth base and the curing material for promoting plant germination, the seeds are protected by the net body and the curing material, which promotes germination and growth and ensures stable construction throughout the year. Becomes possible. Net cover prevents growth base and seed runoff from raindrops and surface runoff.
Prevents the growth base from slipping off from freezing and thawing by covering the net body. It has the functions as described above.

[0005] As a result, greening due to the overgrowth of herbs is obtained on the ground surface such as slopes, collapsed slopes, landslides, and hard rock wastelands that require greening. Contributing to the landscape. However, even in the greening method of the present applicant, technical improvement is still required due to the need for measures to reduce construction costs. The following problems can be considered in common with the related conventional greening method including the patent of the present applicant. In the event of sudden rainfall, torrential rain, or severe frost heaviness in winter during spraying of the growth base, if the growth base material under the greening net is washed away or collapses, repairs are required, and construction costs are added each time. You. Places where the slope of the construction base layer slopes steeply, places that contain rubble, and places where frost columns are generated, that is, rock slopes with more than 45 degrees or weathering or cracks,
In a cold area, etc., such a slope requires a separate wire mesh (typically lath, galvanized iron wire diameter 2.0 mm) before spraying.
mm, a mesh of about 50.0 mm) to firmly fix the growth base material. (For example, Utility Model Registration No. 1592242, "Jiko No. 59-30061"). By the way,
The wire meshing work described above can strengthen the growth base layer, but on the other hand, it leads to an increase in the cost of the greening method and the wire mesh may hinder sufficient growth of vegetation in the future. For example, the roots and trunks of woody plants are tightened and fall down in a strong wind, or in the unlikely event of a collapse due to a disaster, the wire mesh increases the area affected by the wire mesh. In the construction in the dry season in summer, the growth base material is dried, and the germination and growth of plants are not sufficient, and irrigation and additional sowing work are required.

SUMMARY OF THE INVENTION Therefore, the present invention is provided to solve the above-mentioned conventional problems and achieve the object of the invention.

A first aspect of the present invention is a method for growing woody trees using a special mulch in slope revegetation.
After laying at appropriate intervals, seed bags enclosing woody plant seeds on the slope surface such as a collapsed surface, then putting the soil material containing herbaceous plant seeds into a mortar spraying machine and pressing the compressor. The soil is sprayed on the slope by mixing with water at the time of spraying the nozzle at the tip of the spraying hose, and the capillary root of the plant is applied to the growth base layer formed by the spraying. A multi-layered material obtained by laminating a synthetic fiber raschel net onto a web obtained by processing non-woven fabric of ultra-fine polyester short fibers in a random orientation similar to that described above is applied to cover the surface of the growth base layer.

A second aspect of the present invention is a method for growing woody plants using a special mulch in slope greening, wherein a bag containing woody plant seeds to be laid at predetermined intervals on the slope and a herbaceous plant A growth base layer formed to a predetermined thickness by slope spraying on a slope with soil mixed with seeds of a seed, and a web in which non-woven fabric processing of ultra-fine polyester short fibers resembling capillary roots of plants is randomly oriented. And a mulch material which is formed by superposing a synthetic fiber Russell net on the web and extending the surface of the vegetation base layer.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings.
In the figure, 1 is a slope, such as a ground, a lands, a collapsed surface, etc., 2 is a bag enclosing the seeds of a woody plant laid on the surface layer of the slope, and the material thereof is a mesh that is easy to grow. It is preferable to use a plant made of a plant such as a linen cloth or a straw material, but it is also possible to use a polyethylene bag having many small holes. Reference numeral 3 denotes a plant growth base layer, which is made up of a konjac flying powder fertilizer (registered trademark: P-MZAI), a coating fertilizer, and a seed to form a base material. Is sprayed to form a predetermined thickness on the slope while mixing. Reference numeral 4 denotes a multi-material (= Mulch), which is composed of a relatively thin mat-like web (Web = web-like woven fabric) 5 and a chemical fiber Russell net 6. The web 5 is a nonwoven fabric processed in a random orientation with a basis weight of 35 g per 1 m ^{2 of} ultra-fine polyester short fiber resembling the capillary root of a plant. The chemical fiber Russell net 6 is made of polyethylene fiber having a relatively large mesh and light weight, and the web is overlaid and stretched on the polyethylene fiber. The Russell net is assumed to be substantially the same shape and size as the web. The mulch material 4 has a function of covering the roots to protect the roots of the tree, a function of covering the roots, and a function of filtering (filtering with a filter, filtering with a strainer). Is what it is. 7 is an anchor pin for driving the slope 1 from the surface of the mulch material 4, 8 is a seed of a woody plant enclosed in a bag 2 containing seeds, 9 is a herbaceous plant mixed in the growth base layer 3. Seeds.

[0010]

[Specific use example] A concrete construction example based on the above embodiment will be described. That is, seed bags 2 in which seeds 8 of a woody plant are sealed are laid at predetermined intervals on the surface of a slope 1 of a natural mountain, a lands, a collapsed slope, or the like. Next, a growth base material in which seeds 9 of herbaceous plants are mixed, and a soil material in which P-MZAI and a coating fertilizer are mixed are put into a mortar spraying machine, conveyed by compressed air of a compressor, and sprayed. A predetermined thickness is sprayed on the slope 1 while mixing with water when spraying the nozzle at the tip. And the growth base layer 3 formed by the soil spraying
In advance, a web 5 formed by processing non-woven fabrics of ultra-fine polyester short fibers resembling capillary roots of a plant in a random orientation is prepared in advance to a thickness of 5.0 mm, a width of 1.0 m, and a length of 25.0 m to 50.0 m.
m, cut it into the set dimensions and stretched it. After laying the polyester Russell net 6 on the web,
An anchor pin 7 is driven at a predetermined interval to cover the surface of the growth base layer 3. The herb, in which the seeds 9 of the herbaceous plant mixed in the growth base layer 3 germinate, grows from the voids of the web 5 and the mesh of the coarse-grained Russell net 6 to the surface and grows.

When the result of spraying the seed enclosing bag 2 laid on the slope 1 and the growth base layer 3 was observed,
About one tree (or one strain) was established per m ² , and it was recognized that the ground surface was covered by herbs. Therefore, it is substantially suitable to improve and improve the growth environment of woody trees at a rate of about one tree (one strain) per 3 m ² .

[0012]

According to the present invention having the above-mentioned structure, stable germination can be achieved by enclosing the seeds of a woody plant in a seed bag that is easy to grow and curing. In addition, the mulch material having the functions of the mulch and the mulch can prevent the pressure and the erosion of the ground surface due to the invasion of herbs. Further, germination and growth of woody plants can be promoted by the water supply / water retention functions of the mulch material. Furthermore, in the case of greening work, if there is rainfall immediately after the work, the rainwater hitting the construction surface will be drained by the filter function within the thickness of the web, and the growth base will be covered by the rainwater by the root covering and the surrounding fence function. Prevent erosion. Even if a strong wind hits the construction surface, it passes through the web by the filter function of the multi-material. Furthermore, seeds and the like on the growth base surface are not blown away and washed away by the root covering or root surrounding function. In addition, since the heat retention effect of the mulch is maintained even by freeze-thaw in winter, collapse of the growth base or the like is prevented. Next, there are effects such as reinforcement of the conventional method and omission of wire mesh (lath) stretching. As an enhancement of the conventional method, it is possible to prevent the growth base material from flowing out due to rainfall immediately after spraying or in a soft growth base state due to continuous long rain. Rainwater flow during a sudden heavy rain disaster can prevent the loss of growth bases and the subsequent collapse of the slope itself. Freezing and thawing effect of dumping is reduced by the heat retention effect,
Prevents frost collapse of the growth base material. Prevention of drastic evaporation of water due to drought, retention of water, and suppression of drying of the growth base material ensure germination and growth of plants. The above advantages and strengthening functions continue even after the plants have survived, and the safety of the slope itself is further improved. Next, regarding the result that the wire mesh (lath) stretching work can be omitted, the wire mesh (lath) stretching work can be omitted, so that the construction is easy and the construction period is shortened. Cost can be reduced. If landslides such as gravel or weathered rock should occur, the damage will be limited to local damage, and the area affected by the disaster can be minimized. The roots and stems of the woody plants can grow sufficiently and will not fall down in strong winds. The above effects can be obtained.
