The world cup in qatar is a hot fight, and when we scream for the good performance of the players, you don't know if you've noticed the green side of their feet, except for watching the ball。
Man-made fur is a nightmare
Vegetable fibre-fibre capacity in natural turf is limited, as football is generally less powerful on natural turf, allowing athletes to handle leather balls in the field. The fact that much of the man-made grass is made of plastic fibres and is very resilient means that, if high-altitude or rebound balls are dealt with in a game, the athletes have to adjust their position and determine the altitude and route of the rebound of football, which has an impact on their inherent technical tactics。
There's a different kind of friction. Under the same conditions, a rolling distance of 3 to 12 metres for football is considered optimal. Tests showed that the rolling distance of the natural turf site was 4-15 metres and the rolling distance of the man-made grass was 1-10 metres。
Artificial fur is clearly more powerful than the friction of natural fur, forcing athletes to consume more energy at the same time and with the same intensity of motion, and to suffer from premature fatigue, which seriously affects their technical tactics。
Man-made fur is a nightmare for athletes used to natural fur。
The swiss youth team in berne is home to the man-made fur used, and in the 2010-2011 season, the main team, 3-2, defeated the hot thorns of the visit. Redkenap, the hothead after the race, complained that “man-made furs in the home of young people have affected their performance”
In the 2021-2022 season of the european championship, the united united also lost to the young berne. "it's hard to adapt to man-made grass, and such a field shouldn't be in the euroscore."
Mixing the grass is better
In 2018, the natural man-made lawn hybrid system first appeared on the world cup finals. So what's the impact of a hybrid lawn on football
Russia, the host country of the 2018 world cup, does not have a climate suitable for the growth of its natural lawn, and many russian clubs use man-made grass in their home yard. The russian world cup uses a mixed lawn system that combines the advantages of natural and man-made grass, which is supplemented by 95 per cent of natural grass with 5 per cent of synthetic fibres, with a unique air-transmission system capable of excreting excess water from the ground surface within five seconds and of ensuring soil moisture through a pipe beneath the site. Man-made grass can fix roots and help to grow natural grass. Natural grass and man-made grass fibres can co-eave the impact of intense motion. The hybrid system also has the motor, environmental and conservation properties of natural grass, while preserving its durability and greening effects。
Before the finals of the 2018 world cup, the luzhniki stadium had been used for more than 60 hours, which was equivalent to the entire british super league season. In the face of frequent competition pressures, the hybrid lawn system has handed over a perfect response. What about the fur used in the qatar world cup in 2022
On the floor, the best fur is chosen
The annual precipitation in doha, the capital of qatar, is only about 76 mm. So here, plants don't grow easily. From 2014, yasser müller and his team began planting grass on the desert floor。
In the suburbs 20 km from doha, 36 species of grass from all over the world have been sent here to simulate the natural conditions of light, soil and moisture in qatar through six years of continuous testing, and to be screened in layers, to select the hot-seasonal platinum series of freckles that are well developed and extremely resistant to trampling, adapted to the climate of qatar and the requirements of the apex。
It takes one year to grow to the best state and to use anchoring to make it more stable and less vulnerable; it is complemented by the upper-level drainage system at the lower end of the grassland to keep it at its best at all times。
Expert seminar on grass-roots management
In order to present the perfect match and training grounds for the current world cup, fifa has even organized a seminar in doha to bring together the world's finest experts in the field of fur to ensure that the management of the world cup meets the perfect requirements。
In one event, the role of the training stadium was sometimes underestimated, and everyone focused on it, because it was a game, but in practice it might be more important than a competition。
In doha, there are two sites in each of the training fields, which can be used interchangeably and reduce wear and tear。
Qatar has always been proud to have a world-class field of grass, and the asbar centre is the driving force in the pursuit of high-level turf management。
Modern stadium appearances seem spectacular. At the same time, this poses a major challenge to maintaining the quality of the grass. One of the solutions to this problem is to provide additional light to parts of the grassland area using a patchlight grown from the grass。
On the other hand, the maintenance of the grass is being strengthened. The shadow distribution on the turf of the field is not even, so sometimes it has to be divided into shadow and non-shade zones. Qatar has come up with a number of ways to preserve the grass, covering as many areas as possible with light light to achieve a balance of light on the grass。
The mandatory requirement of the experts for the management of grass is to ensure that all fields, including training sites, are of the same quality and that players, regardless of which field they are playing, are given the same sense of foot as they are on the field so that they do not lose control of the field。
Let's hope the players at this world cup are able to run, enjoy the game and play more good
