Maintenance after lawn construction requires more care
Various factors in the construction of a football field are mutually restricted. After it is established, it requires the maintenance and maintenance of professionals.
Aperture helps improve cool-season turfgrass growth
The high-intensity trampling of football will inevitably lead to varying degrees of soil compaction, a decrease in soil aeration and water permeability, and ultimately hinder the growth and development of turf grass. Therefore, controlling soil compaction is crucial for football field lawns.
Drilling holes is one of the most effective aeration measures to solve the problem of soil compaction in football turf. It can control the hay layer, remove soil stratification that may be caused by rolling turf, and increase lawn density and soil permeability.
But for cool-season lawns, the turfgrass roots in the hole will increase, while the roots in the soil around the hole will decrease to varying degrees. Explanation: “Currently, some experts have found that drilling has a greater impact on cool-season lawns than warm-season lawns in terms of improving the quality of lawn play. Drilling affects the physical properties of the soil and the growth of turfgrass, especially root growth. The different conclusions are due to differences in drilling equipment, soil types and turfgrass species.” In addition to drilling holes, puncturing and scarifying the turf are also common aeration and maintenance measures.
Different fertilizers, different effects
In the normal growth of lawns, fertilization is critical to improving the resistance and recovery capabilities of football field lawns.
Fertilization is easily overlooked, especially N fertilizer. Applying too much or too little N will lead to a decrease in the lawn’s trampling resistance and resistance, and will also easily cause the occurrence of lawn diseases. In particular, excessive application of N fertilizer can easily cause a series of changes in the growth and development of turfgrass, such as succulent stem and leaf tissue, reduced stored nutrients, and thinning of cell walls.”
Therefore, cool-season lawns must maintain good trampling tolerance and resistance. The appropriate amount of N fertilizer is 200–300kg/(hm2.a). Warm-season lawns are most suitable to apply N fertilizer every month during their growing season. is 48.9kg/hm2.
Different types of fertilizers have different effects on lawn resistance. Current research has found that the service life of bermudagrass lawns can be extended by applying K fertilizer. Before the lawn enters hibernation, excessive application of N fertilizer will cause freezing damage to the lawn. At this time, increasing K fertilizer will reduce the freezing damage caused by N fertilizer.
Top-applied soil effectively controls the hay layer
One of the most effective measures to control the thatch layer on football field turf is top application of soil. If the hay layer on the surface of the football field lawn is too thick, it will cause water to accumulate on the surface for a long time. Since the infiltration of fertilizers and other materials is inhibited, the surface hardness and friction of the field will decrease.
Top-applied soil is generally carried out after drilling, and the surface of the lawn should be leveled with a rake after application. It is understood that regular surface application of soil can gradually improve the permeability of the soil medium and prevent the formation of a withered layer. It is also beneficial to the recovery of damaged lawns and the long-lasting use of the football field.
Top-applied soil is also often used to change the slope of the field bed. After a long period of use, the surface of the golf course will inevitably produce varying degrees of convexity. This situation can be improved by multiple top-applied soils.
Trimming and rolling
Pruning can increase the density of lawn grass and the smoothness of the lawn surface, but the root system of the lawn grass will be affected to a certain extent. Maintaining different mowing heights will have different effects on the properties of the lawn. Said: “When the mowing height of the lawn changes from 2.5 to 5.0cm, when the mowing height decreases by 0.6cm, the rebound height of the court surface will increase by 1.75cm.”
The main impact of mowing frequency is the rolling distance and rebound height of the football. Its impact only occurs when the new growth height of the lawn grass exceeds 0.3cm between two mowings. Otherwise, its impact on the quality of lawn sports is not significant.
Rolling generally occurs after mowing, which can reduce the friction on the lawn surface and increase the rolling distance and speed of the ball. The impact of rolling on the football field is similar to that of athletes. Therefore, it is emphasized that the time of rolling and the weight of the roller need to be mastered, otherwise rolling can easily have a negative impact on the lawn. ST. It is recommended to use a 454kg smooth roller to roll a lawn with a mowing height of 2.9cm twice. The surface rolling distance will increase by 1.4m and the surface rebound height will increase by 5cm.
Although rolling can increase the smoothness of the court surface, improper operation will lead to a reduction in turf coverage and surface friction.
In addition to maintenance skills, we also care about whether the maintenance staff is sincere and takes good care of the lawn. Scientific conservation is based on a series of technologies. The caregiver should play the role of mother, clearly understand the child’s strengths and weaknesses, and then use strengths and avoid weaknesses to educate him to grow up. Lawn maintenance is only theoretical knowledge. In practice, you need to carry out scientific maintenance based on local conditions and the characteristics of your own lawn.
