Bunkers play a very important role in golf course utilization and are irreplaceable. The maintenance of the bunker lawn of a golf course directly affects the landscape effect of the entire golf course, and the maintenance of the sand surface of the bunker directly affects the quality of the golf ball for guests. A relatively well-maintained sandpit will bring guests the pleasure of playing golf and a more natural landscape effect. Below, I have summarized some precautions regarding the daily maintenance requirements for sand pits and shared them with experts and colleagues.
一. The function of sandpit
A bunker refers to an obstacle area formed by removing turf and soil, replacing it with sand or sand-like materials, and finishing it into a concave shape.
The functions of the bunker are: ① Act as an obstacle to increase the challenge of playing golf; ② Give the course a multi-colored and varied landscape effect; ③ Indicate the direction of the ball.
二. General requirements for sand pits
1. The height of the bunker edge: The height of the bunker edge is generally 4-125px. The cut surface should be neat and the lines should be smooth.
2. Thickness of bunker sand: The thickness of bunker sand is generally around 375px
3. Placement of sand rakes: The sand rakes should be placed close to the edge of the bunker, with the rake teeth pointing downwards and the rake head toward the green. They should be placed in an easily accessible position and evenly distributed. The number of sand rakes should be based on the size of the bunker. to place.
4. Requirements for bunker sand: The appropriate selection of sand will affect the quality of the shot. The color of the sand must be consistent. The size of the sand is mainly 0.25~0.50mm, accounting for about 60% – 70%, it is best to sift the sand. Too fine sand can easily affect drainage. The shape of the sand should be polygonal rather than round, because polygonal sand can make the surface firmer, while round sand is slippery and slippery. Easily blown away and prone to sinking when guests stand.
5. Requirements for the sand surface: The sand surface should be smooth according to the terrain of the bunker, without waves or bulges. The sand should be uniform and clean, with no weeds or grass clippings.
三. Precautions for daily maintenance of lawns near sand pits
1. Watering the lawn next to the sand pit
The lawn area next to the bunker has a large slope and has many noses. It is difficult to water thoroughly when watering. It should be combined with artificial auxiliary watering, and the nose area of the bunker must be manually drilled if necessary.
2. Mowing the lawn beside the sand pit
The lawn next to the bunker should be kept neat and well-defined with the bunker. The nose of the bunker should be round and smooth, with no weeds or bald spots. The lawn mowing height next to the sandpit is generally 3-125px. There is a slope on the edge of the sandpit, and the grass blades are relatively slanted, so the blade of the lawnmower must be sharp when mowing, otherwise the lawn will be hairy and white, but you should also be careful not to cut the grass.
3. Fertilizer management of lawns near sand pits
Pests and diseases on the lawn next to the bunker are easy to be ignored. The lawn next to the bunker should also be well maintained. In particular, the spraying should be careful. It is best to use a separate spray gun and stand in the bunker to spray. Standing on top of the bunker, the spray will be uneven. Moreover, the medicine is usually applied to one side of the grass blades, which cannot achieve the desired effect. The mist sprayed from the medicine gun should be aimed directly at the lawn, so that the medicine fully covers the stems and leaves of the grass. In severe cases, even the base of the stem must be covered.
4. Grass thinning and drilling holes beside the sandpit
The edge of the bunker is relatively steep and groomers and aerators cannot operate. To thin the grass, you can use an artificial tooth rake and rake vertically and horizontally. Drilling can be done manually with a homemade nail board, or with a garden punch (which is relatively dangerous, so please pay attention to safety during operation). The entrance and exit area of the sand rake machine at the edge of the bunker should be drilled regularly to prevent and control hardening, about once a month during the grass growing season, and can be managed and maintained according to specific conditions.
