Golf water use is a sensitive topic, especially in China, which ranks only 121st in the world in terms of per capita water resources. Water conservation has always been an important issue for environmental protection. According to the 2011 “Toward White Paper – China Golf Industry Report”, the average annual water consumption of my country’s 18-hole course facilities is about 323,000 tons, which is 58% higher than the same figure in the United States of 188,000 tons. The commonly used control of the irrigation system in the golf course is to use computers to calculate pressure, water flow, nozzle size, water window, adjustment percentage, wind speed, temperature, circulation and penetration, gate opening and end time and many other items to control the lawn on the golf course. Water usage, noncommittal, that’s a huge leap. However, as long as there is slight rotational inaccuracy, the nozzle is worn or used incorrectly, the nozzle layout is poor, or the nozzle rotates too fast or too slowly, it will destroy the optimization effect of the computer sprinkler irrigation system program. This will not only reduce its use effect, but also affect Saving water doesn’t help either.
In order to achieve conservation and environmental protection in irrigation, the uniformity of irrigation water is the decisive factor. Poor irrigation uniformity is the main reason why a golf course is wet all day long, and it is also the main factor causing water waste. The construction cost of a relatively high-standard 18-hole golf course is about 80 million yuan, but many investors have invested more than 20 million yuan to build standard courses. The result of construction is extreme cost reduction. The most common compression is the irrigation and drainage system, which is invisible but very important for later maintenance. Because the irrigation system is inherently insufficiently equipped and does not have the support of advanced water-saving hardware equipment, it causes the later maintenance of the course to use water. Stay high. A well-designed and high-quality irrigation system provides an even distribution of irrigation water through the system, thereby eliminating over-wetting as well as over-drying. An 18-hole golf course in the United States has about 20 maintenance personnel plus a director. This is inseparable from the high degree of mechanization of American golf courses, the clear division of tasks by the director, and the efficient and accurate execution of workers. At the same time, the good foundation laid in the early construction of the stadium is the main reason. Their irrigation systems and pipelines are rarely repaired, while in China, various problems will occur after more than three years of use. Therefore, reasonable planning in the early stage of construction is the primary basis for ensuring uniform irrigation water and thereby achieving water conservation in irrigation.
For our country’s golf courses, in the cold northern regions, due to the long non-irrigation period, it is generally sufficient to inspect the irrigation system once a year before starting irrigation in spring. In the southern region, due to the long irrigation period and even the need for irrigation throughout the year, the irrigation system is usually required to be inspected at least twice a year. But in fact, the inspection here should refer to a comprehensive inspection of pipelines, control systems, etc., because even the best sprinkler/nozzle combination may not perform satisfactorily in terms of irrigation water distribution after being used for a period of time. Therefore, this requires During the daily use and maintenance of the irrigation system, lawn staff make timely and appropriate adjustments to the irrigation system based on actual conditions, and this adjustment is much simpler than we expected. You only need to check whether the spray angle of each nozzle is set correctly, whether the nozzle rotation is normal, whether there are grass blades, grass roots and other debris that affect the normal operation of the nozzle, whether the nozzle is worn, whether the sealing ring is leaking, etc. Sometimes it is also found that the nozzle shell is broken And the built-in filter of the nozzle is clogged. Most of the above problems are not difficult to detect and solve. As long as the staff pays a little attention, the stadium can save a lot of money.A research report from the California Sprinkler Irrigation Technology Research Center shows that it is only necessary to simply modify the rotating sprinkler head or do some other maintenance measures, such as adjusting the angle and height of the sprinkler head, to restore it to its optimal state. In this way, subtle adjustments can adjust the uniformity of water spraying, and easily save approximately 6.5% of water for sprinkler irrigation. And this only saves water. Reducing the use of the water pump can also save energy and extend the service life of the water pump by about 2 years.

For the irrigation of many golf courses, we directly drill wells to tap high-quality groundwater, or use clean surface water from rivers and lakes for irrigation. This will cause competition with urban water supply, rural drinking water for people and livestock, and agricultural and forestry irrigation, resulting in excessive water consumption in the golf course. Large, unfavorable situation such as saving resources. Saving water from the source should be a priority for today’s golf courses: water sources that can be exploited by the golf course include landscape lake water in the golf course, domestic wastewater from the clubhouse and surrounding residential areas; as well as natural rainfall, build some stormwater utilization facilities in the golf course, and fully collect sidewalks, Rainwater on roadways, parking lots and building roofs. This water is treated and becomes gray water, which can be used to irrigate the stadium lawn and form a circulating water chain within the venue. There is no need to worry about using gray water to harm the quality of the lawn. On the contrary, gray water irrigation is safe for the lawn and the effect is better than using high-quality groundwater for irrigation. Because gray water contains certain organic matter, it can not only reduce the impact on high-quality underground drinking water The mining can also save a lot of fertilizer costs.
