Description

Technical Field

[0001] The present invention relates to the technical field of sports lawns, in particular to a construction method for planting sports lawns in southern regions in winter. Background Art

[0002] Warm-season turfgrasses are best grown at temperatures between 25 and 35 degrees Celsius. Growth slows below 25 degrees Celsius, and they enter a dormant period below 15 degrees Celsius, experiencing slow growth and withered leaves. Cool-season turfgrasses are best grown at temperatures between 15 and 25 degrees Celsius. Growth slows above 25 degrees Celsius, and above 35 degrees Celsius, their leaves begin to wither and die. The grass height on sports lawns is generally around 25mm, while warm-season turfgrasses are typically only 15mm tall during their winter dormancy. This is especially true in southern China, where they are planted in November. Due to the low temperatures, they typically only grow roots and stems, not leaves, and can be less than 10mm tall. Cool-season turfgrasses are perfectly suited to growth, generally exceeding 25mm tall, meeting the needs of sports.

[0003] Warm-season turfgrasses, such as Zoysia and Bermudagrass, are widely used in sports fields in southern China due to their heat, drought, and trampling resistance. However, warm-season turfgrasses enter a dormant period in winter (after November), with the aboveground parts withering and turning yellow, only beginning to green again in late March of the following year. CN102550259A describes a method for mixed planting of cool-season and warm-season turfgrasses in the northern transition zone. This technique is the closest to existing technology, but it suffers from the following serious drawbacks: 1. Since two different varieties of grass seeds are sown and grown at the same time, there will be serious color difference problems due to the different colors of the two grasses, and the "uniformity" index of sports turf cannot be met.

[0004] 2. Since cool-season grasses have difficulty surviving the summer in southern regions, they will all die in June of the following year. The conversion to warm-season grasses is poor, resulting in bare patches, requiring large-scale replanting or even replanting of warm-season grasses. Summary of the Invention

[0005] The purpose of the present invention is to provide a construction method for planting sports lawns in winter in southern regions, which can improve the landscape effect of sports venues.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: A construction method for planting sports lawns in southern China in winter comprises the following steps: S1. Winter warm-season grass planting: After the root layer is carefully leveled, plant warm-season grass turf or stems and cover with 5-6 mm of sand. S2. Warm-season grass maintenance and management: Water the grass at preset intervals. Gradually increase the watering intervals and the duration of each watering group based on the survival of the warm-season grass turf or stems. Once the warm-season grass is fully established and green, proceed to the next step. S3. Use a reel mower to mow warm-season grass to a height no greater than 15 mm. S4. Sowing cool-season grasses: Sow cool-season grass seeds throughout the field and cover with sand 2.5-3.5mm thick to completely cover the seeds. S5. Covering with non-woven fabric: Cover the entire field with non-woven fabric or perforated plastic film to maintain the temperature and humidity of the root zone, ensuring that warm-season grasses take root and cool-season grasses germinate; S6. Cool-season grass maintenance and management: Water the grass at preset intervals. Gradually increase the watering intervals and extend the watering duration of each group of grasses based on the germination and rooting of the grass seeds. After 16-20 days, remove the non-woven fabric and fertilize once a week. After 2 months of maintenance, the grass can be delivered for use. S7. Conversion between cool-season and warm-season grasses: Mow the lawn every four days until the end of March of the following year, leaving no more than 30mm of grass height each time; from April of the following year to the end of June, mow the lawn every six to eight days, leaving no more than 25mm of grass height each time; spray the lawn growth inhibitor once every two weeks to ensure that the cool-season grass is completely degraded and the entire field is covered with a single variety of warm-season grass.

[0007] Furthermore, in step S2, in the maintenance and management of warm-season grass, watering is performed every 2.5 to 3.5 hours, and each group is watered with tap water for 4.5 to 5.5 minutes each time.

[0008] Furthermore, in step S4, the sowing rate of cool-season grass seeds is 16-20 grams per square meter. For mixed sowing of warm-season and cool-season grasses, the sowing rate of cool-season grass is particularly critical, as it has a significant impact on the lawn. This application uses a sowing rate of 16-20 grams per square meter. If the sowing rate is too low, the coverage of the cool-season grass on the field will not meet the sports lawn stem density index; if the sowing rate is too high, the cool-season grass will be too dense, affecting the growth of the underlying warm-season grass.

[0009] Furthermore, in step S2, the maintenance and management time of the warm-season grass is not less than 15 days.

[0010] Furthermore, in step S6, in the maintenance and management of cool-season grass, watering is performed every 2.5 to 3.5 hours, and each group is watered with tap water for 4.5 to 5.5 minutes each time.

[0011] Furthermore, in step S6, after 18 days, the non-woven fabric is uncovered, and fertilizer is applied once a week thereafter. After two months of normal maintenance, the plant can be delivered for use.

[0012] Furthermore, in step S7, the lawn is mowed every five days from November to the end of March of the following year, and the height of the grass left each time does not exceed 30 mm.

[0013] Furthermore, in step S7, the lawn is mowed once every 7 days from April to the end of June of the second year, and the height of the grass left each time does not exceed 25 mm.

[0014] Furthermore, in step S1, the warm-season grass turf used is the warm-season Zoysia japonica Lanyin No. 3 turf roll.

[0015] Furthermore, in step S4, the cool-season grass seeds used are cool-season ryegrass seeds.

[0016] The beneficial effects of the present invention are: 1. Solved the problem of large color difference in lawn and improved the landscape effect of sports venues.

[0017] 2. It ensures the conversion effect of cold-warm season mixed grass to warm season grass, eliminates the phenomenon of bare ground, and eliminates the need for large-scale replanting or re-planting of grass, thus reducing engineering risks. BRIEF DESCRIPTION OF THE DRAWINGS
