in order to ensure the healthy growth of artificial grass

In what conditions or circumstances, must table fertilize soil, in order to ensure the healthy growth of artificial grass? Normal lawn table Shi processing can also be strong growth, but under the following conditions must table Shi soil. ① in very poor soil (no fertilization, subsoil, shale, sand, earth, etc.) built lawn covered in the surface layer of sieve out the stones, the fertile soil of the impurities is useful. ② when the lawn surface irregular colonization of the newborn lawn are very uneven one o'clock, one or more surface application the subsidence part of the soil can fill a newborn turf. ③ can generate a large number of creeping bentgrass sticks grasses such as creeping stems Ying, etc., consisting of artificial grass in the periodic table applied soil conducive to the elimination of severe surface flocculation.

What are the major causes of degradation caused by lawn? artificial grass after the use of a period of time, many problems occur. Large tracts of bald bare patches, and even lawn abandoned. Common reasons: Lawn selection mistakes; lawn low-lying stagnant water, waterlogging, poor drainage; barren soil, strong acid or alkaline; irrigation too much, too low mowing lawns excessive use, pest, frost, drought damage; depressed severe soil compaction; lot of weeds invade damage; thick thatch layer; poor soil physical properties, poor ventilation; woods shade, sun. Solve the above problem, in addition to the improve lawn soil infrastructure, strengthening the management of water and fertilizer, weed control and pest, can be used on the local lawn minor surgery to repair perforated ventilation to remove thatch repair bald bare patches, so that recovery growth potential to become a quality lawn. If the artificial grass bald bare area, unable to restore growth and vitality, or weed cover more than 50%, has lost its value in use, it is necessary in accordance with the intended use and funding conditions to measure whether or not to pursue a comprehensive renovation.

What is the appropriate leaf spot disease conditions? How to prevent and treat?

The the lawn occurrence of disease by which factors?

What is the principle of prevention and control of turf diseases? A brief description of the specific practices. "Prevention first, comprehensive prevention and control, we must first investigate the frequently-occurring species and harm local onset period, in order to advance prevention. Second, to strengthen the lawn of conservation and management measures, such as actively prevent weeds, timely pruning, irrigation and fertilization, artificial grass can improve the ability of the resistance to disease.

Brief artificial grass trimmed.

Brief artificial grass trimmed. A: lawn moderate pruning to control its height, to keep the lawn neat and beautiful, and promote lush growth of grasses to increase and promote the softness and flexibility of the lawn, people step on the felt certain stretch to accommodate people play and the need to rest. Mowing the lawn can inhibit lawn weed flowering and fruiting, reduce weeds eliminate the edge of the long grass of the lawn, keep the lawn around the edge of the beautiful environment, especially artificial grass for people to watch, more should strive neat appearance, can reduce pest damage to promote the the lawn healthy development, can promote sub calyx increased the lawn layer of dense and flatness.

Following artificial grass planting program to sort: before planting weeding, debris clean-up, flat, Environmental Investigation determine grasses, planting, cover soil covering, crackdown, rotary tiller, irrigation.

Sunny place relative to the artificial grass lawn under the shade of a tree, the pruning height What is the difference? Why? The area of ??light and tree shade lawn should improve repair grass height to reduce the density the lawn per unit area on increase per plant lawn grass, lawn grass can adapt to the shade of the environmental conditions.

After punch with a hollow cone, artificial grass will often appear wilting or new weeds appear, why? How to reduce these side effects? (1) temporarily undermine the integrity of the surface of the lawn. (2) Since the exposed turf soil layer, and thus cause the dehydration of the lawn grass. (3) when the conditions for the germination of weed seeds, tend to generate a lot of weeds. (4) accelerated harm habitat cutworms and other pests in the. Select the time of the punching is very important. Should choose the punch is more appropriate in the case of artificial grass to grow lush, good growing conditions. Punch in vigorous lawn growth period, interspecific competition can effectively inhibit weed seedling growth and development, in order to achieve the purpose of biocontrol. Perforated surface fertilization and watering is carried out immediately after the lawn grass dehydration can be effectively prevented. The the soil core drag level crushed and lawn replay process through partners Shi selective herbicides can effectively control weeds. In addition, the appropriate choice of the addition to the soil core and replay time can avoid the maturation and germination of weed seeds growing season.

The construction process of the artificial grass football pitches

1, based on: venues foundation for artificial grass venues play a crucial role. Flatness, stability and drainage of the site based on the effect of the use of the artificial grass venue will affect.
artificial grass for infrastructure and standards. Currently used in the artificial grass sports ground the basis of the type of asphalt concrete, waterproof concrete type, gravel base and thirty-seven soil foundation. Choose what kind of foundation type and drainage system is considering the functional requirements and economic conditions of the venue. The requirements of the international football bodies venue is steady and stable, recommended asphalt base, multi-select drainage pipeline, cold weather region hopes to increase geothermal systems. The ordinary stadium or school playground is actually multi-select the Turtle structure outside the drainage structure, consider the basis of the life of the construction as well as convergence with plastic venues based domestic Stadium applied asphalt concrete foundation is relatively common.
The site should be designed in accordance with local geological report of the sports venues, the location of the annual precipitation and maximum precipitation, the location of the site to inspect. the basis of artificial grass sports grounds into a carrier of the artificial turf, the quality is good or bad will directly affect the performance of the artificial grass football field.
The artificial grass football stadium venues based basic stability, and does not collapse.
According to its structure can be divided into a variety of surface: asphalt concrete surface layer, reinforced concrete surface limestone surface, and seeds stone surface layer.
Asphalt surface is more popular in the country, which itself has a waterproof, can not direct water penetration inclined to rely on the venue slope drainage. In the rain when the venue stagnant water together into a small water, resulting in the loss of the quartz sand, rubber granules lawn to the edge of space will be too much water, stagnant water in a short period of time is not easy to discharge. Reinforced concrete surface layer there are also the same problem.
And two limestone surface layer gray No. adjustable smaller seeds stone itself, ash-free number, better water permeability of both surface-based. Stone the same size with the size of the stones of the asphalt surface the rainwater can directly penetrate below the gravel layer and dry hard soil, thus reducing the loss of fat rubber particles of quartz sand on the lawn, to ease the venue hydrocephalus situation. However, both the surface layer can not be used in cold winter areas. Penetrate the surface layer of the water can not be discharged, will be in the winter section the ice swell, causing the site surface uneven phenomenon.
Two limestone stone surface layer of the surface layer of seeds have good water permeability, and the surface layer and asphalt, relatively cheap price. Therefore recommend using two the limestone surface layer, and seeds stone surface layer as venues basis of artificial grass football field, but more in the winter cold areas or use asphalt or cement surface.
The venues foundation with asphalt or cement surface layer can refer to road construction requirements, but pay attention to maintaining the overall shape of the construction, the venues middle surrounded by low, the slope should be evenly maintained at 0.3% to 0.5%, and venue to be set up around the drainage ditch. The two limestone surface layer, and seeds venue base of the stone surface layer requirements of embedded drain line.
Regardless of the basis for its quality directly affects the quality of the surface layer is good or bad. Foundation construction, based on prime soil generally follow the Technical specifications for construction of road infrastructure, reinforced concrete layer generally follow Highway Cement Concrete Pavement Construction Technical specifications and asphalt concrete layer generally follow the technical specifications of the highway asphalt pavement construction;
2, put the line, to identify venues center point according to the center point fixed site on each point, the exact location of the line. Reference sports venues field deployment site marking, drawing graphic design and effect diagram, match the performance and the thickness of the artificial grass.
3, based processing, repair, clean-up. The artificial grass moved into the site along the lateral edge direction to spread, and sequentially from one end of the longitudinal edges of advance to the additional information about one end. artificial grass to be used by professionals specialized tools laying. Into the material to reach the construction site, in accordance with the requirements of the drawings, by construction workers cutting, each lawn seams mouth coated with a special interface with glue connection or using a special machine sewing together as a whole, the entire lawn. Installation requires air humidity can not be too large, to avoid the rainy or foggy weather construction.
4, will be the preparation of the in white lawn outside grass lines cut, placed on the side stand.
5, the green lawns seams lap 2cm ~ 3cm, with cut grass cutter or knife cut to lap close as possible so that both sides of the lawn.
6, 20cm ~ 30cm wide fiber cloth or nonwoven fabric spread along the seams of the lawn was water wet, need sulfate, and then drying a certain time so that the special glue evenly coated on the fiber cloth, and then pieced together from both sides of the lawn, adhesive fiber cloth. If you put together at the gap may be in addition to every 2cm ~ 5cm cut a stretch to the interface at to ensure beautiful appearance.
7 lawn basic splicing after, again PULL fix individual function lines of the site, the location of the point, to the cutter cut out of the cut wire grass into the fiber cloth, coated special glue to the original ready The white wire grass back into the cementation pressed. Arcs in the corner narrow area difficult the whole corner area removed, cut into small pieces, block by block back into the stitching together.
Lawn splicing after arrangements will fold on the lawn to knife opening, straightened docking resection overlapping part, and then cemented
9, lawn all dealt Note sand, sand filling machine Note colloidal particles, bristles. On the lawn, filling quartz sand, quartz sand hidden in the grass roots of the silk, and play a role in protecting the turf. And quartz sand evenly spread over the rubber particles. Filling the quartz sand and the thickness of the rubber particles according to the different heights of the lawn, depending on requirements of the rubber particles is less than about wire grass surface about 10mm.
10, clean up the site, check the site specific size, strict inspection lawn bonding is firmly deal with the phenomenon of uneven quartz sand and rubber particles layer, and finally completed.

to see the trajectory of the development of the artificial grass industry

If you have a business, always engaged in an industry for nearly 10 years, compared to the spectator it must have more insights in this industry. Beijing on November 2, 2012 international sports surface science co-organized by the venues Resources Association (ISSS) Forum, Ltd. from Taishan artificial turf industry YangXiaoBing wonderful speech for the attendees about the Taishan the course of development of the artificial turf, but also to see the trajectory of the development of the artificial grass industry.

In his speech, Yang Xiaobing mentioned the late 1990s, artificial turf products to enter the Chinese market, and quickly led to the development of the artificial grass industry, the beginning of the 21st century, the Titan Group, Jiangsu ZhongLian company began production of artificial turf its main business as raw material, the use of imported turf lawn weaving production, low-tech. With the the artificial grass growing domestic production and processing enterprises, domestic and gradually form the enterprise cluster industry is dominated by several large companies, also began to pay more attention to product development work, trying to create a domestic market requirements artificial turf.

Venues resource network to understand, as one of the large R & D and production enterprise of the domestic artificial turf industry Taishan artificial turf industry Co., Ltd. is a microcosm of the artificial grass industry, the course of its development. Processing on behalf of low technology content, to continue to expand the scale of production, the further development of the product R & D work, Taishan Group to achieve rapid development of the national brand of artificial grass industry.

Leapfrog development obviously can not be separated from the needs of the market for artificial turf products. ? YangXiaoBing Statistics, 1990 years, China has nearly? 1? Square meters of artificial turf stadium; 1999? Years, the application area of ​​growth? 50? 000 square meters; in 2001? Years, the application area is reached? 150? Million square meters. Changes in the relationship between supply and demand has also led to the development of enterprises and the rise of a large number of artificial grass. However, as the market expands, some problems are gradually exposed.

Shoddy, the gradual emergence of low-end products to hit the market, cheap malicious competition, the emergence of this phenomenon is the "bottleneck" has a great relationship with the domestic product development. To this end, the the Taishan Group and other domestic enterprises with anti-aging properties of the artificial turf, wear resistance, soft performance, invest a lot of funds for the purchase of advanced instruments, equipment, and employ professional and technical personnel, machinery and equipment, ancillary equipment.

Inputs after the domestic artificial grass manufacturers for a long time, the effective integration of the artificial grass market. The research and development of artificial grass environmental durability and comfort, the national industry of artificial grass products has been recognized by more people.

YangXiaoBing artificial turf because of its unique weather resistance, maintenance economy, save water without the need for spraying pesticides, weather characteristics are widely used. With mankind the popularity of the sport, as well as the football on artificial turf license to use, at the same time due to expand the use of artificial turf, artificial turf will continue to maintain a faster speed increments. Future, artificial turf will be showing a durable, soft and comfortable, recyclable recycling characteristics. Artificial grass industry development prospects will be better.

There are many advantages of artificial grass

There are many advantages of artificial grass, for example: the green of its four seasons, the appearance of bright, lively, good drainage performance, long life and low maintenance costs.

artificial grass sports system based on quality requirements are mainly concentrated in three areas: hardness, flatness and drainage slope.

The artificial lawn foundation three categories: asphalt base, cement foundation, gravel base, which type is mainly determined by the local climate and environment and the budget, time, asphalt base, especially for the northern large temperature difference between climate and environment and low winter temperatures, also because it is expensive for a warm, humid environment is not the most suitable foundation type, gravel foundation because of its simple construction, low cost, rapid drainage, more common in the South, but because of its rigidity and stability prone to the foundation loose after prolonged use, leading to uneven foundation; Therefore, in most regions of the domestic cement concrete foundation became economic cost is very high base type of artificial grass.

Double and sports a wealth of experience in the artificial grass system, synthetic grass cement concrete foundation do brief as follows:

1, higher requirements on the basis of surface flatness, to ensure that the artificial turf surface layer of uniform thickness, uniform elasticity. Flatness pass rate above 95%, and 5 m ruler error 3MM, slope: horizontal 8 ‰, vertical 5 ‰, the semicircle area 5 ‰, the surface should be flat, smooth, to ensure drainage.

2, the base should have a certain amount of strength and stability.

3, uniform surface and solid, no cracks, no bad side pockmarked face, straight and smooth seams, 6000mm × 6000mm cuts as well.

4, cushion compaction, density greater than 95%, after the pressure of the medium-sized rolling machine, no significant round track, no surface dust loose, wave phenomena such.

Cement foundation necessary aquifuge the new PVC thickened aquifuge impermeable film, the junction should be greater than 300mm edge margin greater than 150mm.

6 need to consider the extension gap width of 5 mm.

7, soccer grass the basis of the maintenance period of 2-3 weeks.
