Super North Stadium has become a vegetable field. Can artificial grass really solve the problem?
As the most famous vegetable field in China, Zhengzhou Maritime Sports Center was once notorious and was criticized in the first round of the league. After the debut of Yanbian Fude Super League on April 2, head coach Park Tae ha appealed at the post-match press conference whether the venue of Yanji People's Stadium could be better. Recently, Li Tie, Kangka and Eriksson all expressed their dissatisfaction with Changchun Economic Development Stadium. In fact, because of the climate in the north, the growth of grassland can't be as lush as in the south. Then, can we use artificial grass instead of natural grass? You know, 80% of the home court of the Russian super team is artificial grass.
Why use artificial grass? Most of them are forced.
North Korea's Wuyi Stadium is the largest stadium in Asia, which is paved with artificial turf. At that time, our commentator once lamented how good the venue was. In fact, artificial grass is paved here, which completely reaches the level of confusing the real with the fake. In fact, using natural grass is a compulsive factor. One is the climate, and the other is the high maintenance cost of natural grass. The latitude of Russia is higher than that of northern China, so they must be colder. The competition time of Russian Super League is similar to that of Chinese Super League, which is March-165438+ 10. In March-May, June10-June165438+1October, the weather was cold, which was not suitable for the growth of natural grass, so their professional football leagues were basically held in artificial grass. The reality is that Russian Super does not use artificial grass, and the competition will be played on frozen mud for several months.
The home of Russia, the famous Luzhniki Stadium, is artificial grass. The Champions League final was held here (Manchester United beat Chelsea on penalties), and it will be the final venue of the 20 18 World Cup. In fact, with the continuous progress of science and technology, the high-end artificial grass stadium that can be certified by FIFA as a two-star venue is not much different from natural grass. However, professional football players are still skeptical about artificial grass.
How much is artificial grass? Top artificial grass is more expensive than natural grass.
Basically, the price of artificial grass we come into contact with will be different due to the influence of material, needle spacing, base cloth, grass height, density, row spacing, pound weight and parameters. The price range is 30- 100 yuan/square meter. The official football field is about 7000 square meters, which is laid according to the standard of 100 yuan/square meter, and the cost is about 700,000 yuan. The price of venues that can hold Super League and higher level competitions, that is, those that need to pass the FIFA star standard certification, should be around 2 million, while the price of ordinary natural grass courts is only 1/2 of the price of artificial grass. However, the price of natural grass in the famous Shenyang Olympic Sports Center is 6.5438+0.3 million yuan, while the price of natural grass in Nanjing Olympic Sports Center is 2 million yuan.
The service life of ordinary artificial grass can reach 5- 10 years, and there is basically no maintenance cost, which can lower the price of natural grass, but the maintenance cost is amazing. The maintenance cost of European clubs is 3 million euros a year, which translates into more than 20 million RMB. Domestic maintenance costs vary from venue to venue, but they are not low. For example, a maintenance master said, "After a high-intensity training class, the damage of the turf field can reach nearly a thousand places. It needs immediate maintenance and labor costs. At the same time, we should have all kinds of maintenance and insect prevention. "The difference between natural grass and artificial grass now is that artificial grass has high investment in the early stage and basically no cost in the later stage. Natural grass investment is not high, but it is bottomless in the later stage. "
FIFA has a certification standard for artificial grass.
In view of the problem that natural lawns can't be used in winter, FIFA has been promoting the artificial lawn course plan in recent years. To this end, FIFA has specially formulated the standards of "one-star certification" and "two-star certification". "Two-star certification" stadiums can host World Cup finals and Europa League competitions, and one-star certification venues can host FIFA's subordinate low-level competitions, national teams' warm-up matches, leagues, finals, European Cup preliminaries and champions leagues.
At present, the stadiums that have passed FIFA's "two-star certification" in China include Ordos Dongsheng Sports Center (the first one) and Beijing Technology and Business University Stadium. To everyone's delight, the artificial grass used by the two companies is made in China, one is Chuangchuang in Jiangsu and the other is Aosheng in Guangzhou. That is to say, China's artificial grass is a world-class professional player, and the conclusion is that it is only a little worse than natural grass. However, this kind of artificial grass court is rare in China.
Artificial grass hosted the World Cup.
20 10 World Cup Group C match, Slovenia-Algeria match was held at Peter Mokaba Stadium, and artificial grass (70%) and natural grass (30%) were mixed. This is the first time that artificial grass has entered the World Cup. 20 14 World Cup in Brazil all used natural grass, but all the training venues provided by Brazil for each team were artificial grass courts produced by China Company 2065438. It's completely fake.
Some clubs in the five major leagues are artificial grass.
Although England issued a ban in 1995, it is forbidden for professional clubs to use artificial turf courses for competitions. However, all clubs have artificial turf courses. For example, the artificial grass stadium in Chelsea's cobham training ground was built by Chinese enterprises. Laurian is the only team that uses artificial grass in Ligue 1 and even the five major leagues. On the other hand, Nancy and Valentina and their team also use artificial grass, including Hercules and zwolle. Italy has last season's first-class team, cesena Austrian Salzburg Red Bull, and the venue is also artificial grass.
Which is better, natural grass or artificial grass? We still need players to speak. The famous Dutch star Gullit said: "Playing football on artificial grass is like wearing a condom, which is very uncomfortable." However, Fabregas also said: "Both natural grass and artificial grass can play football, which is not the decisive factor in winning or losing the game." H and z talk about their feelings.
1. What's the difference between artificial grass and natural grass?
H: Natural grass is soft, but artificial grass is hard. We train every day, and there should be harm on artificial grass.
Z: The court is hard and the ball speed is different.
2. What harm will it do to the players?
H: knees and ankles
Z: ankle, ankle and knee
3. How long does it take for artificial grass to adapt?
H: Actually, it's not much difference. I think it's mainly because the height of the ball is different after landing. It's only one or two training sessions, and everyone is playing in the same environment.
Z: Let's split up. I should be fine, because I used to play football a lot. The stress points on artificial grass are different.
4. Is it necessary to change equipment when kicking artificial grass?
H: You can't wear steel nail shoes. Foreign artificial grass can wear plastic spikes. If it's like artificial grass in domestic universities, you can only wear small broken spikes.
Z: You have to change! One more thing, there is basically no difference between the artificial grass I have kicked abroad and the natural grass. That venue is still very different from the schools around us.
