A piece of high-quality turf can really improve the players' skills and tactics on the field, but do you know what kind of turf is a high-quality turf?
Turf species
At present, human beings have not found a grass that can meet the needs of all courses and can be specially planted on the court. The species of grass on football field in different regions are different. The grass planted in different seasons on the same football field is different, and even the grass planted in the same football field at the same time is also different.
In order to meet the needs of football, which is a kind of high-intensity and fierce confrontation sport, the turf of football field must meet the following conditions:
(1) In order to reduce the injury probability of athletes as much as possible, the grass must be soft;
(2) In order not to affect the rebound rate of the ball, the flexibility of the lawn grass is also good, otherwise the players will be upset;
(3) The most important thing is that the trampling resistance of turf grass in football field should be very strong, there should be a revolutionary optimism spirit of "players abuse me a thousand times, I only treat him as the first love"; also have strong recovery ability, such as drought resistance, cold, insects, diseases and so on.
At present, most professional stadiums in China are planted with turfgrass, which are divided into cold season turfgrass and warm season turfgrass according to geographical location and season.
Cold season turfgrass, such as Poa pratensis, Lolium perenne, Festuca arundinacea and so on, are usually used in North China.
Festuca arundinacea is very common in the course of our country, especially in the course with low operating cost. It is the most drought and trampling resistant grass species in the cold season turfgrass. It adapts to a wide range of soil types, is resistant to poverty and thin, sensitive to fertilizer, and has good salt and alkali resistance. It is the first choice for the course with low management level and poor soil quality.
Perennial ryegrass (Lolium perenne L.) is an important cold season grass of gramineous ryegrass. It has the advantages of developed root system, strong tillering ability and so on. It is widely used as lawn grass. In addition, perennial ryegrass is a perennial sparse clump grass with dense fibrous roots and good density. However, it has poor cold resistance and is considered to be the most sensitive cold season turfgrass to low temperature stress. It is suitable for cool and humid areas without severe cold in winter and heat in summer, and adapts to a wide range of soil types. Compared with tall fescue, perennial ryegrass is much more delicate, but it is trample resistant and grows fast. The most important thing is that the turf is soft and soft enough to make you want to fall or fall.
In the south, warm season turfgrasses, such as bermudagrass and Zoysia japonica, are commonly used in the south. The former is known as the "dominant grass species" of warm season turfgrass. It is widely used in various golf courses, golf greens and parks in the south, with fine texture, dark green color and trample resistance.
Zoysia, which belongs to the subfamily caudatum Gramineae, is widely distributed in the coastal areas of Asia, Africa and Australia, and is very "resistant to exercise". It is drought resistant, wear-resistant and trampling resistant. It has good elasticity, but it also has hard leaves with short green period.
Do good grass seeds mean good turf? No, no, no, a high-quality natural football turf must also meet the requirements of soil, field slope, stem and leaf density, etc.
