Embodiment 1

[0022] (1) According to the construction standard of the sports field, remove 35cm of loam on the surface of the site and then level and compact it. After laying a 10cm gravel layer, mix river sand and yellow sand in proportion (river sand: yellow sand = 0%: 100%) with peat and nitrogen, phosphorus, and potassium The compound fertilizer is mixed evenly outside the field, and then laid on the gravel layer of the lawn bed. The thickness of the substrate is 25cm. After the laying is completed, it is scraped and compacted, and the lawn is planted after watering;

[0023] (2) Plant 'Yangjiang' bermudagrass on the lawn bed by direct seeding method, the planting ratio is (1:5);

[0024] (3) In the second and third years after the lawn is established, the simulated trampler is used for trampling treatment, trampling 3 times a week (each trampling intensity is equivalent to two football games), 3 months a year, a total of 72 times trampling.

Embodiment 2

[0026] (1) According to the construction standard of the sports field, remove 35cm of loam on the surface of the site and then level and compact it. After laying a 10cm gravel layer, mix river sand and yellow sand in proportion (river sand: yellow sand = 20%: 80%) with peat and nitrogen, phosphorus, and potassium The compound fertilizer is mixed evenly outside the field, and then laid on the gravel layer of the lawn bed. The thickness of the substrate is 25cm. After the laying is completed, it is scraped and compacted, and the lawn is planted after watering;

[0027] (2) Plant 'Yangjiang' bermudagrass on the lawn bed by direct seeding method, the planting ratio is (1:5);

[0028] (3) In the second and third years after the lawn is established, the simulated trampler is used for trampling treatment, trampling 3 times a week (each trampling intensity is equivalent to two football games), 3 months a year, a total of 72 times trampling.

Embodiment 3

[0030] (1) According to the construction standard of the sports field, remove 35cm of loam on the surface of the site and then level and compact it. After laying a 10cm gravel layer, mix river sand and yellow sand in proportion (river sand: yellow sand = 40%: 60%) with peat and nitrogen, phosphorus, and potassium The compound fertilizer is mixed evenly outside the field, and then laid on the gravel layer of the lawn bed. The thickness of the substrate is 25cm. After the laying is completed, it is scraped and compacted, and the lawn is planted after watering;

[0031] (2) Plant 'Yangjiang' bermudagrass on the lawn bed by direct seeding method, the planting ratio is (1:5);

[0032] (3) In the second and third years after the lawn is established, the simulated trampler is used for trampling treatment, trampling 3 times a week (each trampling intensity is equivalent to two football games), 3 months a year, a total of 72 times trampling.

Abstract

The invention relates to a lawn bed constructing method capable of improving trampling resistance of a lawn in a sports field. The method comprises the following steps: removing soil of a surface layer of a bed base, after the bed base is tamped smoothly, spreading a gravel layer, uniformly mixing commercially-available river sand and yellow sand outside the field according to a certain ratio, andspreading the mixture on the bed base, wherein an optimal mixing ratio of the river sand to the yellow sand is 60%:40%. According to the method disclosed by the invention, a sports lawn bed is constructed by the method, physical and chemical properties of a lawn bed substrate under the conditions of sporting and trampling are improved, the compactness of the lawn bed substrate is significantly reduced, growth of roots of the lawn in the sports field is promoted, abrasion resistance of the overground part of the lawn is improved, and the trampling resistance of the lawn in the sports field issignificantly improved.

Description

technical field [0001] The invention relates to a lawn bed construction method in the technical field of lawn field construction, specifically a method of mixing river sand and yellow sand in a certain proportion to improve the trampling resistance of various types of sports lawns such as football fields and tennis courts. sexual method. Background technique [0002] Sports lawn refers to a special venue where the lawn is used as the carrier of competition, sports and game activities. Almost all sports are accompanied by strenuous exercise or high-intensity and high-frequency trampling on the lawn. Therefore, in addition to the characteristic characteristics of general green spaces, sports field lawns must also have strong trampling resistance. [0003] The lawn bed is the foundation of the turf in the sports field, and it is also one of the most important factors that determine the quality of the turf in the football field. Since the natural soil in the sports ground are...
