Description

[Detailed description of the invention]

The present invention relates to a turf vegetation construction method for growing beautiful turf from seeds on slopes of vast developed areas, golf courses, river banks, parks, roads, airports, etc. Conventionally, there are three methods for planting lawns, which can be broadly classified as follows. (1) Method of dispersing seeds directly. (2) A method of spreading fresh grass of a certain size. (3) A method of installing pine containing seeds such as vegetation boards or vegetation zones. Among these methods, the first drawback is that it cannot be applied at all to slopes where seeds and fertilizers are easily washed away, or to poor soils that lack nutrients for germination and growth, and it requires a great deal of fertilizer management. This not only requires time and effort, but also results in uneven greening that impairs the aesthetic appearance. Next, the disadvantages of the second method are that the season for growing fresh grass is limited, and it is not suitable for mass production.Also, during construction, transportation and burying work is difficult, which lengthens the construction period. Furthermore, fertilizer management also requires a great deal of effort. Next, the disadvantage of the third method is that it uses fast-acting chemical fertilizers, so growth after germination is poor, and it cannot be applied to poor or sloping land, so its range of application is limited. It is something that In other words, since the above-mentioned lawn vegetation method had an extremely narrow scope of application, further research has progressed and currently methods such as hole construction and striation net construction have been developed as methods for greening areas where vegetation is difficult to grow. has been done. However, even these methods have the drawbacks of long construction periods, bare green areas, and poor landscapes due to long grass. The present invention has been made by making earnest efforts to eliminate the drawbacks of the conventional construction methods as described above, and has developed and completed a completely new method for constructing turf vegetation.
The purpose of the present invention is to form a beautiful green lawn even in areas where greening is difficult, to shorten the construction period and save labor, to easily secure quantities, to have no restrictions on the construction period, and to reduce soil and sand. The object of the present invention is to provide a lawn vegetation construction method that has various advantages such as forming a lawn while protecting against erosion. Next, the construction method of the present invention will be explained in detail below using construction examples shown in the drawings. First, the material composition used in the construction method of the present invention can be roughly divided into a vegetated turf zone 1 and a slow-release organic soil 2. One of the vegetated turf zones 1 consists of vegetative seeds 1a, granular chemical fertilizer 1b, and non-fertilized organic soil. Consisting of woven fiber 1c and net 1d, the other slow-release organic soil 2
consists of artificial soil, a covering entangling material, and an adhesive, and each constituent material will be explained below. Vegetation Seeds 1a are short grass varieties that are selected to form beautiful lawns in place of conventional fresh grass (Korea grass), and the selected varieties are Kentucky bluegrass mellion and short grass vermiform. Judas U-
3 and seaside bentgrass, and one or more types of these are mixed depending on the construction period and discussions with the owner. The granular chemical fertilizer 1b uses a germination promoter and a highly chemical granular compound fertilizer, and its components are 10% nitrogen, 10% phosphoric acid, and 10% or more potassium. The nonwoven fibers 1c are made of a material that can envelop the seeds 1a and the fertilizer 1b in the fibers to prevent them from scattering, and that will be assimilated into the soil over time. The net 1d prevents the slow-release organic soil 2 from being washed away and stabilizes the shape of the vegetation lawn zone 1. It is made of a thin polyethylene material and is formed into a mesh shape that disappears over time. .
The artificial soil is mainly composed of humus soil made from chicken manure, with the addition of water retaining materials, adsorbents, adhesive materials, and growth substrates as auxiliary materials.The composition list of the artificial soil used in the construction example is as follows:

[Table] The characteristics of this artificial soil are as follows. Because it contains a large amount of organic matter, it has good fertilizing properties and is highly effective for soil improvement. Humus soil particularly increases water and fertilizer retention, improves aeration, and promotes the growth of bacteria. Contains inorganic ingredients and organic fertilizers necessary for plant growth. The effect of the additive improves capillary action and promotes hydration. The covering entangling material is mainly made of wood cellulose, and is a mixture of short fibers of crushed paper and long fibers of hemp, and has an enhanced anti-washing effect due to the entanglement of both long and short fibers. The adhesive material consolidates the intertwined portions of fibers, promotes soil fixation, and improves washout resistance and water retention. Next, an example of the construction method of the present invention will be explained.
The construction method shown in Fig. 1 is a construction method that is applied to bare earth embankments made of good quality soil with gentle slopes and flat areas. Net 1 attached to one side of
As shown in FIG. 4, a vegetation grass strip 1 (Fig. 3) consisting of d is laid on the construction surface S with the net 1d as the upper surface, and the adjacent vegetation grass belts 1 and 1 are laid with the mesh skewer 3. After that, the slow-release organic soil 2 is spread over the entire surface of the vegetated lawn zone 1 by a mechanical method pressurized by a pump and passed through a hose 4 and a nozzle 5, as shown in FIG. This is a method of spraying. In addition, the construction method shown in Figure 2 is a construction method that is applied to slopes without fertilizer, hard soil, weathered soft rock, whitebait soil, sandstone, crushed rock, etc., where vegetation cannot be expected. Before installing 1, first spray slow-release organic soil 2, or add the same soil 2 together with additional soil.
This is a construction method in which the soil at the greening area is improved by spraying to form a construction surface S, and then a vegetated grass strip 1 is laid down and slow-release organic soil 2 is sprayed. In addition, a green coloring agent may be added to the slow-release organic soil 2 used in the construction method of the present invention in addition to the above-mentioned mixed material. This will ensure both construction and aesthetics. Therefore, the turf vegetation construction method of the present invention, as described above, includes a vegetated turf zone 1 using ultra-high-grade seeds (specific Western grass) and a slow-release organic soil 2 that takes into account runoff resistance and water retention in addition to long-term fertilizer effects. Since this is a method in combination with the following, it has the following effects. (1) It forms highly pure lawns in a wide range of applications, including areas where greening is difficult such as slopes and poor soils, and the vividness of the green surpasses that of Korai grass. (2) Vegetation grass zone 1 is lightweight and slow-release organic soil 2
Because it can be mechanically sprayed, it has excellent workability and can shorten the construction period and save labor. (3) Since the vegetation turf zone 1 and the slow-release organic soil 2 are produced in factories, it is easy to secure quantities, and the construction can be carried out over spring and autumn, depending on the selection of seeds. (4) In greening bare land, grass can be formed while protecting the slope of the embankment from washing away with the vegetated grass belt 1 and the slow-release organic soil 2. (5) The greening of the soil on the constructed embankment surface and within the legal frame will have the effect of preventing erosion due to reliable grass growth.
