In the one week after laying the sand, you need to observe the sand on the grass leaves every day before mowing the grass. If there is sand on the leaves, you need to start the nozzle and press the sand on the leaves with water. The nozzle rotates 1 circle.
In the season suitable for lawn growth, about 4 days, the leaves damaged by drilling and dragging sand have been basically cut off, but the new leaves are still relatively soft and easily infected by viruses. They are also not resistant to rolling and trampling. At this time, you can spray fungicides and foliar fertilizers to improve the disease resistance of the lawn. Foliar fertilizers mainly supplement magnesium, iron, phosphorus and other trace elements. Magnesium and iron can promote photosynthesis, and phosphorus can promote root growth and improve resistance.
One day after spraying foliar fertilizer, you can roll it once and spread thin dry sand to improve the smoothness of the green surface. Then you can appropriately reduce the mowing height, and the height should be reduced by 0.1mm every day. As long as there is no grass shoveling, it will be reduced to the ideal height you think. If grass shoveling occurs, it means that the surface of the green is not flat enough and needs to be leveled with sand.
At this point, we have to talk about the green speed.
When your Bent grass greens scissors are 2.8mm high, the green speed should be above 10.5. Of course, there are still some differences in the greens cut at the same height by different models and brands of mowers. If the green speed does not reach 10 at a mowing height of 2.8mm, then you have to look at the humidity of the green. If the humidity of the green is high, the impact on the green speed is still relatively large.
Another problem is that if the density of the lawn is too dense, the ball will encounter greater resistance during rolling, which will also cause the speed of the green to slow down. On the contrary, if the density of the lawn is insufficient, the ball will jump during rolling due to the insufficient smoothness of the green surface, thus reducing the speed or even changing the line. This is the most painful situation for players to putt on the green. The former situation can be improved by thinning the grass and spreading sand, while the latter situation needs to be improved by supplementing nutrients and spreading sand.
In daily maintenance, the most important thing for the green is water control. Excessive humidity will cause poor root system of the lawn, weakening its disease and drought resistance. Excessive fertilizer will easily cause the lawn to grow too fast, which will also affect the speed of the green ball and cause waste. The use of fertilizer on the lawn should be based on the results of soil tests to adjust the content of various nutrients. Granular fertilizer should be used only when there is physical work. Spraying foliar fertilizer every 10 days or so will have better effects and reduce costs.
The green is the core part of a golf course. The quality of the green is directly related to the income of the golf course. Good greens can attract more players.
