After investigating the market, it is understood that most of the lawns used in golf courses in southern my country are hybrids of bermudagrass. Each hole of the golf course consists of 4 main areas, namely the tee area, fairway, obstacle area, and hole area. Among them, the lawn grass in the hole area requires the highest quality. To manage the lawn grass in the hole area, you need to pay attention to the following issues
Method/Step
1. Grass cutting: In order to obtain a satisfactory hitting effect, the height of the grass must be between 3-6.4 mm. Therefore, if someone is playing every day, unless it rains, the whole area must be cut every day before the athletes are on the court.
2. Irrigation: As the frequent cutting of grass causes the plants to form shallow roots, which reduces the ability of the plants to absorb water from the soil, and the soil under the ball area contains a lot of sand with poor water retention capacity, so the lawn in this area should be kept in good condition. It must be watered frequently, and spray a few minutes of water at noon when it is hot and dry. Watering time is carried out in the evening when the court is not in use.
3. Change of the ballpoint: the location of the ballpoint area should be changed several times a week. The specific frequency depends on the degree of trampling and abrasion of the lawn around the ballpoint, so as to avoid excessive trampling on the local lawn.
4. Fertilization: According to the growth situation, soil mixture, climate, the type of fertilizer used, and other variable factors, every 100 square meters of lawn needs about 0.37-0.73 kg of nitrogen fertilizer in each growth month. The amount of phosphorus and potassium is determined based on the results of soil analysis.
5. Perforated aeration: Perforate the soil or plow the soil at least once a year to improve the aeration of the root system.
6. Adding soil: mixing soil-adding materials into the withered grass layer on the soil surface can increase the decay rate of the withered grass and make the lawn flat. Sand is generally added, and a thin layer is added every 3-4 weeks.
7. Disease and insect pest control: Many pathogens and insects will seriously harm the ball hole area, even a slight injury can temporarily damage the ball-hitting quality of the ball hole area. It is recommended to use Cajunqing for sterilization and prevention.
