The continuous high temperature in summer is undoubtedly a huge challenge to the healthy growth of turf grass. For stadium managers, how to manage the lawn well under the continuous high temperature, maintain the good condition of the lawn, and ensure the normal operation and operation of the golf club. Meeting the guests’ playing requirements is undoubtedly a severe test. Currently, what problems are domestic golf lawns facing in summer management, and how do lawn directors everywhere deal with them?
The most important issue is pests and diseases. When it comes to summer management of golf lawns, diseases are a concern for everyone. Regardless of whether it is in the north or the south, golf lawns are susceptible to diseases such as brown spot, Pythium wilt, summer spot and fairy ring disease in summer, as well as underground pests such as chafers and grubs. In severe cases, the lawn will die in pieces, which not only affects The ornamental effect of the lawn will also affect the quality of golf for guests, which is directly related to the normal operation of the golf club.
Based on our many years of work experience, daily maintenance and management is a very important aspect of golf lawn diseases in summer. Generally speaking, for golf turf diseases to occur in summer, the following conditions usually need to be met:
Long-term high temperature and high humidity; excessive use of nitrogen fertilizer in summer; excessive watering or watering for too long, causing the grass blades to stay wet for too long; mowing in the evening; excessive hay layer. In addition to the weather, which cannot be controlled by humans, the conditions for disease occurrence caused by other management factors such as fertilizer, water, and pruning can be adjusted through careful management, thereby avoiding the occurrence of major diseases.
In order to avoid diseases causing major harm to the golf course, although these diseases occur in summer, their prevention work runs through the maintenance and management work throughout the year. In particular, prevention must be focused on combined with the infection process of the disease, and the effect will be better. The daily maintenance process should focus on prevention. Once you are infected with the disease, you must take timely measures and prescribe the right medicine. At present, the golf course maintenance technology is relatively mature. The key is to detect it as soon as possible and control it properly so that it will not cause harm.
The core of management: detailed resistance. Among the various measures for summer lawn management, as long as the arrangements are made around one core – enhancing lawn resistance and breaking the conditions for disease occurrence, the problems in summer management will be easily solved. This is a common conclusion reached by experienced lawn directors. These management measures include water, fertilizer, mowing, drilling, combing, sand covering-top dresser, etc.
In terms of water management, be sure to pay attention to the time of watering. Avoid watering in the evening or evening. You can choose to water in the early morning or morning. Do not water too much. In order to improve the drought resistance of plants and promote root growth, irrigation should be reduced as much as possible without affecting the surface quality of the lawn. The plants can be slightly drought stressed between two irrigations. There is a foreign watering method. Water at noon every day and control the water volume to 0.5-1 cm. It can not only prevent insects and diseases, but also cool down the plants.
In terms of fertilizer management, attention should be paid to maintaining the nutritional balance of the lawn, paying attention to appropriately reducing the amount of nitrogen fertilizer used, and applying more long-acting compound fertilizers.
In terms of mowing, attention should be paid to increasing the mowing height, reducing the frequency of mowing, and clearing the withered grass layer in a timely manner. Pruning tools should be disinfected to avoid the spread of diseases. In addition, I would like to remind everyone to pay attention to a detail, that is, to remove the dew before pruning, because dew is not only the condensation of water vapor, but also contains many products of plant metabolism, which can easily cause disease.
In other aspects, in order to maintain the permeability of the soil and promote root growth, the lawn needs to be auxiliary management such as drilling holes, combing grass and covering with sand in a timely manner.
In short, the management of golf lawns must pay attention to details, improve the resistance of the lawn through management, and put prevention work in front, so as to avoid the occurrence of pests and diseases to the greatest extent.
