Description

Filling material for soil improvement of natural or hybrid turf system

The present invention relates to a filler for soil improvement in a natural turf or hybrid turf system, and more particularly, to a filler in soil in which natural turf or hybrid turf is planted, which can exhibit nutrient supply and drainage effects as the filler in the soil.

Further, the present invention relates to a filler for soil improvement of a natural or hybrid turf system, which can exhibit nutritional supply and drainage effects and air permeability, thus requiring less maintenance and facilitating management for the growth of natural or hybrid turf. .

In general, in outdoor playgrounds such as sports-related soccer fields and baseball fields, as a means to protect the body of athletes from intense sports events, or as a means to provide emotionally beautiful scenery to people walking in a garden or promenade, various purposes depending on the location The lawn has been cultivated as a means to achieve

In case of natural grass, only the epidermis of the planted soil is removed and transplanted to another place, the natural grass roots are excited and cannot be maintained firmly. In Korea, where the winter season is long, natural grass fields are used for about 40 to 50 days a year. If it is only work and the use is restricted to protect the lawn, the efficiency of the playground drops sharply, and careful attention is required for management such as watering and feeding due to damage.

In addition, when a stadium is formed using only natural grass, it is easily dented and damaged by external shocks to create an irregular surface, impeding performance and increasing the risk of injury to players. Artificial turf was developed.

However, artificial turf is often avoided due to abrasions caused by heat during kicking or sliding, or injuries due to heat generated.

Research on hybrid turf fields utilizing the advantages of natural turf and artificial turf as described above is being actively conducted.

In general, in hybrid turf fields, a layer of foam is laid on the playground, sand is sprayed on it to a certain thickness to form a layer of sand, and then natural grass seeds are sown. Created by stitching until

More specifically, the hybrid turf field is a mixture of natural and artificial turf. Starting with a mixture of 80% natural grass and 20% artificial turf, recently, a turf composed of 98% natural turf and 2% artificial turf has been released.

The proportion of natural grass is overwhelmingly high. In other words, in the form of putting one artificial turf between the natural grasses, in the form of inserting the artificial turf into the ground like a needle, and by inserting needles (artificial turf) at regular intervals, the bond between the natural turf can be strengthened.

Both natural turf fields and hybrid turf fields use filler materials. In the case of natural grass, the filler is called soil sand, and the soil sand serves to improve the soil by forming a topsoil layer on the lawn.

However, conventional soil sand often contains a lot of clay, and in this case, the solidification rate of the soil is very fast, which leads to poor drainage, and when a large amount of it is used, the surface of the grass is excessively covered, and the growth of the grass is temporarily inhibited or It may exhibit yellowing and, in extreme cases, may die off.

It is necessary to develop a filler for soil improvement that can prevent the above problems.

In addition, in the case of natural turf, periodic ventilation, that is, aeration operation and drainage is required, but in the case of hybrid turf, artificial turf is included, so it is difficult to smoothly perform aeration operation, so it is important to secure air permeability in the soil.

Accordingly, in order to solve the above problems, it is possible to exhibit nutrient supply and drainage effect and breathability, so that it requires less maintenance and is a filler for soil improvement of a natural or hybrid turf system that facilitates management for the growth of natural or hybrid turf. development is needed.

The reality is that stadiums and playgrounds for various sports are being nurtured with great emphasis on the aspect of human health and residents' harmony along with the development of the region. In particular, due to the rapid development of social and physical education, the number of small-scale sports facilities is rapidly increasing, and the situation of the playgrounds sensitive to sudden changes in weather is also recognized as one of the urgent tasks to be solved.

In general, sports stadiums or playgrounds require quick drainage to remove water from the surface of the stadium due to intensive rainfall or artificial irrigation, and at the same time, pressure resistance to withstand the hardening of the ground caused by the pressure of athletes and turf management equipment is also required. Rather, it should be easy to protect the body from impact, etc., and the surface should have a flat surface.

The USGA method announced by the United State Golf Association (USGA) green section is a green construction method for a golf course, with a total porosity of 35 to 55% and a saturated permeability per hour of 150 to 300 mm (0.25 to 0.51 mm) or irradiation. (0.5 to 1.0mm) It is composed of five layers: a planting layer at the center, an intermediate layer composed of royal sand (1 to 4 mm), a gravel layer composed of soybean gravel, a drainage layer, and the ground.

However, since the USGA construction method was invented as a construction method applied to golf courses, it is not suitable to be applied as it is to the playground where the pressure of players and turf management equipment is evenly applied.結) phenomenon occurs, there is a problem that the water permeability is significantly lowered.

On the other hand, according to the USGA construction method, there is an advantage of improving the water holding capacity and water permeability of the planting layer by mixing the sand and a small amount of organic matter in the planting layer where the grass roots are formed.

However, a phenomenon in which microorganisms present in the planting layer produce a wax-like substance in the process of decomposing organic matter, or a wax-like substance produced by a fungus (basidiomycetes) in the planting layer coats the soil particles in the planting layer. There is a problem in that the dry spot (dry spot), which is a phenomenon, occurs and the grass shows dry or dead symptoms.

In addition, when a dry spot phenomenon occurs in the planting layer, the water permeability of the planting layer is significantly lowered and water accumulates on the surface. Accordingly, when the temperature rises to a high temperature, the temperature of the stagnant water rises, causing a phenomenon such as boiling the grass. It became a problem that the grass died.

In order to solve the above problems, a different method of composition or a different planting method has been devised, but the problem caused by the soil itself used for the planting layer has not been solved. , there is a problem that the improvement of the fundamental problem is not made.
