Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention mainly relates to a method for growing grass on steep slopes such as rocks.

B. Conventional techniques and their problems It is extremely difficult to grow grass on steep rock surfaces, and to date no definitive method has been found. The simplest conventional mud blowing method involves spraying mud mixed with seeds directly onto the rock surface.
This construction method had the disadvantage that the soil did not adhere firmly and could fall off the slope or be washed away by rain.

In addition, even if vegetation were to grow on the slope, the soil layer is extremely thin, resulting in a shortage of fertilizer in a short period of time after vegetation, and for a certain period of time after vegetation, it is necessary to spray fertilizer every four seasons. The drawback was that it required a lot of effort to maintain and manage. In the mud blowing method, a method was developed that allows vegetation to grow on steep slopes where vegetation cannot grow, by digging a large number of holes at predetermined intervals on the slope, filling the holes with seeds and soil, and growing vegetation. However, this method not only requires time and effort to dig many holes in the hard rock surface, but also has the drawback that grass can only grow in spots, and it takes many years for the grass to cover the entire slope. It was hot. Furthermore, even with this method, it was not possible to put as much soil into the holes as needed, and the fertilizer dried up in a relatively short period of time, making it necessary to spray the fertilizer every four seasons.

In order to eliminate these drawbacks of conventional vegetation methods, the present invention has been developed by fixing solid fertilizer with pine strips, fixing nets over the entire slope, and spraying seed-mixed soil on top of the nets. An important object of the present invention is that it can be easily and easily planted on steep slopes, that it is extremely unlikely to collapse after vegetation or that it will be washed away by rain, and that the belt-shaped pine can be used as a solid fertilizer. To provide a method for vegetating a slope, in which the amount of fertilizer applied after the vegetation is fixed, and the maintenance effort after the vegetation is greatly simplified.

C. Means for Solving Conventional Problems The slope vegetation method of the present invention involves fixing belt-shaped pine covering solid fertilizers placed at predetermined intervals on the slope, and placing nets on the top surface of the belt-shaped pine. The process consists of the process of stretching the net, and the process of spraying soil mixed with seeds onto the net.

The band-shaped pine itself has water permeability and is formed considerably thicker than the net.This band-shaped pine is made by spreading solid fertilizer and forming convex parts on the slope with the solid fertilizer. protrude from

Furthermore, the band-shaped pine is fixed in multiple stages on the slope with a predetermined interval above and below, and then soil mixed with seeds is sprayed onto the surface of the band-shaped pine and the surface of the net.

The band-shaped pine and net in which convex portions are formed with the spread solid fertilizer prevent the top soil from being washed away, and the solid fertilizer in the band-shaped pine fertilizes the seeds in the top soil over time.

D Functions and Effects According to the present invention, in addition to covering the entire slope with the net, it is considerably thicker than the net, and moreover,
The solid fertilizer spread forms a convex part,
Water-permeable pine strips that protrude from the slope and are fixed are fixed vertically apart, and soil is sprayed on top of them, so the mesh of the net, the pine strips, and solid fertilizer create height differences on the slope. The soil is fixed on top of the soil, thereby preventing the soil from collapsing after vegetation and being washed away by rainfall.

Band-shaped pine does not just add a step to the surface of the slope, but it also has water permeability and allows the solid fertilizer to flow down the slope over time due to rainfall, etc., so it can quickly reduce the slope surface. The entire area can be covered with vegetation, and the grass that grows will more effectively prevent the slope surface from collapsing and being washed away.

In addition, since the fertilizer spread within the pine strip is a solid fertilizer, it is sustainable, and there is almost no need to spread fertilizer after planting, which has the excellent effect of greatly reducing labor after construction.

Furthermore, in the vegetation method of the present invention, solid fertilizer is spread on water-permeable pine strips, and seed-mixed soil is sprayed onto the pine strips and nets, so the thickness of the pine strips and the solid fertilizer spread are different. The fertilizer is sprayed onto or deposited on the belt-shaped pine trees that protrude from the slope, creating a water-retaining dam on the slope. Rainwater that flows concentrated in several places is distributed by band-shaped pine trees that protrude from the slope and is supplied to a wider area. In particular, this rain water is retained near the band-shaped pine trees where water tends to accumulate and is supplied to solid fertilizer. Moreover, since the top surface of the pine strip is covered with soil, rainwater drying inside the pine strip is suppressed.
To improve water retention in the vicinity of belt-shaped pine where plants can most easily propagate, and to realize the excellent effect of allowing plants to grow thickly in this vicinity, especially during short periods of time.

The slow-release solid fertilizer does not lose its fertilizing ability even after plants have been propagated near the belt pines, and the rainwater supplied here can be used to fertilize a wide area over a long period of time, allowing it to be used on slopes. Plants grow thickly throughout.

The unique and excellent feature of the present invention is that in addition to fixing the solid fertilizer on the slope using the belt-shaped pine,
This method can be achieved through a unique structure in which seeds are mixed with soil and the mixture is sprayed onto the entire slope including the surface of the pine strips, and then the pine strips are made to protrude from the slope using solid fertilizer. .

The above-mentioned features are the most important characteristics for slope vegetation construction methods, and all conventional vegetation construction methods
It was developed with the goal of realizing this feature.

However, until now, no construction method has been successful in creating short-term vegetation on soft rock slopes, and the present invention is the first to realize this characteristic.

E Preferred Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, the slope vegetation method of the present invention includes the steps of fixing strip-shaped pine strips 3 covering solid fertilizers 4 placed at predetermined intervals on a slope surface 1; It consists of a step of stretching a reticulated net 2 over the entire upper surface, and a step of spraying seed-mixed soil 5 onto the belt-like pine 3 and the net 2.

The belt-shaped mat 3 is a non-woven fabric in which natural or synthetic fibers are three-dimensionally bonded to create the required voids, and this is cut into a belt-shape with a thickness of, for example, 5 to 20 mm, and this belt-shaped mat 3 is horizontally The solid fertilizer 4 is laid down and fixed to the slope 1 in a substantially horizontal direction, vertically spaced apart, for example, by 10 to 50 cm, in steps, as shown in FIG.

The belt-shaped mat and the net 2 are most easily fixed to the slope by nailing them.

As shown in FIG. 2, the net 2 is stretched over the strip mat 3.

By the way, the preferred width of the strip pine is 10 to 50
cm, and the mesh size of the net should be, for example, 10 to 50 mm, to minimize the loss of soil.Furthermore, it is best to spread 1 to 10 pieces of solid fertilizer per 1 square meter of the slope. .

For example, a solid fertilizer formed into a rectangular parallelepiped with sides of 1 to 5 cm can be used.

Also, on top of the net 2 and strip pine 3, there are 1 to 3
It is best to spray 5 cm of soil.
