Why is sand covering required on golf courses? An old engineer or veteran worker may answer that sand covering is beneficial to the growth of lawns. Some construction-related professional supervisors or owners may say that this is how it is designed on the drawings, due to the special characteristics of the sports venue. In fact, from the perspective of soil science, sand beds are definitely not conducive to plant growth. First, they do not retain water, and second, they do not retain fertilizer. But why is a large amount of sand used as a lawn bed in the golf course?
First of all, in terms of historical origins, modern golf was born on the Scottish coast, and the original golf courses had many sand beds. The original golf grass species lived in seaside sand beds and had good adaptability to the sand beds. Later, with the development of golf, the tradition of covering the flat bed with sand was brought to many other types of golf courses.
Secondly, from the perspective of the particularity of sports venues, golf lawns, especially the lawns of greens, fairways, and tees, have a very different feel under your feet than ordinary garden landscape lawns. It is not allowed to be stepped on. It looks very beautiful, but there are bumps and bumps when you step on it. However, the golf lawn feels like carpet when you step on it. It is really a great enjoyment to step on that lush green carpet. The grain structure of sand is smaller than that of soil, so the sand bed can be made flatter and smoother than the soil bed. At the same time, sand beds as sports venues provide better protection for athletes than soil beds.
Third, from the perspective of the particularity of grass seed maintenance, modeling and sprinkler irrigation in golf courses, why are the vast majority of golf courses in China covered with sand, which is beneficial to the growth of lawns. This is mainly a drainage problem. Due to the low mowing requirements of the stadium lawn, the maintenance intensity of the lawn is significantly higher than that of ordinary garden landscape lawns. In many places, the shape cannot drain naturally, so blind drainage is needed. The sand bed is conducive to drainage, that is, there is It helps the lawns in many places not be damaged by waterlogging. Therefore, in special golf venues, sand beds are conducive to the growth of golf course lawns.
Fourth, in terms of the nature of the land used for golf courses, no matter which country it is in, golf is definitely a big user of land. Thousands of acres of land are definitely very rare, especially for a country like ours with many people and little land. Many good lands, such as cultivated land, can no longer be used for golf course construction due to national policy restrictions. Most of the golf course land that the author has come into contact with is floodplains, swamps, beaches, fish ponds, mountains, etc. The sand beds are relatively In these places, it is relatively conducive to the growth of lawns.
Fifth, the relative economy of sand beds. Under normal circumstances, sand is more expensive than soil, especially planting soil. However, in places such as seaside and river beaches where sand is particularly convenient to be used, sand beds are undoubtedly cheaper than soil. In some places, the difficulty or high cost of buying and selling earth due to some man-made reasons has also affected the economics of sand beds. In addition, using sand beds to plant grass in northern autumn can greatly reduce the impact of weeds on the quality of lawns, thus greatly improving the quality. Relatively speaking, it is cost-effective.
In summary, golf sand covering has its special historical origins and practical significance. Understanding the ins and outs of sand covering on the golf course can more scientifically determine the sand covering thickness and sand covering area, which has certain guiding significance for the design and construction of golf courses. At the same time, the purpose of writing this article is also to serve as a starting point, do some scientific tests, use data to speak, and guide the scientific design and maintenance of the golf course. To refute the negative views of some public opinion that the stadium affects the environment.
