The uniform color of golf course lawn is the most basic requirement for a golf course. However, any golf course that is more than ten years old has improper maintenance measures, resulting in a variety of lawns with different colors, which has an extremely negative impact on the landscape of the golf course. Therefore, how to solve the problem of different colors in the old golf course, and how to solve the problem of different colors in the new golf course Preventing the problem of uneven lawn color is a common concern for many golf course builders.
Reasons for different colors
1. The variety is impure, that is, the original grass species contains other grass species. Some cheaper grass species are often less pure.
2. When sowing artificially mixed varieties, the sowing container and the container for sowing other grass seeds should be strictly separated.
3. After sowing, the seeds were not covered with non-woven fabrics or other covering materials, and then they were splashed by water or blown by strong winds, causing the seeds to fly around.
4. The variety of the spare grass is not the original variety, and the color will be different after the grass is replenished.
5. The number of annual bluegrass increases year by year, causing serious lawn spots.
Prevention and control measures
1. Choose a good variety
As grass seeds, we should try our best to use varieties that have achieved good response through many years of practice, so that the market supply and demand are large and easy to obtain. As for some cheap varieties, firstly, the purity is not high, and secondly, the market demand is small, and the varieties are changed frequently, making it difficult to purchase in the future. Different varieties of reseeding will definitely result in different colors of the lawn.
2. Prevent the mixing of varieties in the later stages
Eliminate the mixing of later varieties with good fruit; New Gorade, thin leaves, good disease resistance; Subtropical Paradise 419; some seaside paspalum in the south; Zoysia grass in Shandong Peninsula, etc. People have been using these varieties for more than ten years, and the response is generally good.
3. Sow seeds strictly according to the procedures
When sowing, mark each sowing container with the sowing variety mark for exclusive use. It is strictly prohibited to sow multiple varieties in one sowing container. If you really don’t have a seeder, you can sow one variety first, rinse it thoroughly, and then sow another variety. Never use the same container to change varieties frequently.
Use lime powder to draw the dividing line of the varieties, then look at it from a high place, and then make appropriate adjustments. When sowing, use plywood for mobile isolation, or use colored strips of cloth to pave along the line to prevent different varieties from crossing the line.
Once the seeds are sown, the seeds must be rolled up and rolled, and the seeds must be covered with non-woven fabrics. This can not only prevent the seeds from being blown away by wind and splashed by watering, but also keep them warm and moisturizing, improve the germination rate of the seeds, and wait until all the seeds have germinated. After budding, the non-woven fabric is removed one after another. This is an effective and indispensable measure to prevent the mixing of varieties.
Daily maintenance measures
1. Establish grass preparation areas strictly according to the original varieties
The species in the grass preparation area must match the species of the original golf course. If the original variety cannot be obtained, the grass mounds cleared out by drilling can be spread flat in the grass preparation area, and then a thin layer of sand can be spread. This method can be faster than sowing to create a turf, and can also save costs and produce the same grass as the original variety. of spare grass. If it is really impossible to obtain grass mounds, you can also comb the grass in the dense grass area, scatter the grass clippings in the grass preparation area, and spread the sand to raise seedlings to obtain the same backup grass as the original variety. Physical measures include:
⑴ All grass cuttings are required to be carried with a bucket to move the grass clippings out of the stadium to prevent the cut grass stems from taking root and propagating in other places.
⑵In the water pool for irrigation, it is prohibited to pour grass clippings to raise fish to prevent the remaining grass clippings from being carried to other places with the irrigation water for reproduction.
⑶Remove non-required varieties in a timely manner. No matter how careful management is, over time there will always be non-required species growing out of place, such as bentgrass, annual bluegrass, tall fescue, etc. in the fairways. The scariest things on fairways are bentgrass and annual bluegrass. These two types of grass reproduce quickly on fairways and have strong encroachment capabilities.
Although bentgrass is used as fairway grass in some places, if it coexists with bluegrass or other species in the fairway, other grasses cannot compete with it and will gradually disappear. In this way, the area of bentgrass will become larger and larger, and the area of materia medica will become smaller and smaller. Bentgrass has few root systems in the soil, and its main root system is a root network formed on the soil surface. It is extremely intolerant to drought, requires frequent sanding, and is very susceptible to coin spot disease.
Since annual bluegrass seeds fall at different times, they can bloom and set seeds all year round, especially in May, followed by October and November. The flowers in May are purple, and most of the flowers in other months are white. , it takes about 10 days from flowering to seed maturity. After the seeds fall to the ground, they have a strong germination ability, so its development speed is also amazing. This grass is slightly lighter in color than perennial bluegrass. The biggest difference between it and perennial bluegrass is that it has no underground stems and dies after setting seeds.During this period, the lawn will become partially yellowish, and the original color will not be restored until the seeds that have fallen to the ground germinate and grow. If this grass is not controlled, it can damage your lawn very quickly. There is currently no good way to cure it, but some people recommend cutting its roots and combing the grass frequently to inhibit its flowering and seeding.During the seed-setting period, mow low and use a bucket to remove grass clippings from the field. In short, it is best to remove it while it is young to avoid future troubles.
