What about the soil hardening of golf greens?

A new technology to fill the blank of green maintenance technology was born.

There are still many loopholes in the maintenance technology of golf greens, and there are also many immature technologies about the maintenance of golf greens. How to make lawn managers spend the least maintenance cost and get the maximum return is what we are waiting for. A brand-new product CE that can transform golf greens was born, which brought good news to our golf maintenance work.

The first thing to talk about is irrigation, which is essential for the daily maintenance of the green. The sand-based lawn bed on the green has poor water-holding capacity, and low pruning will reduce the water absorption capacity of lawn grass to a certain extent, so it is necessary to adequately irrigate the lawn to ensure the vigorous growth of lawn grass. However, the increase of water will inevitably lead to poor soil permeability, and lawn diseases are prone to occur if the humidity is too high. How to balance the moisture content in soil? This requires soil improvers, and CE soil conditioner can solve this problem.

CE has the characteristics of improving soil water holding capacity under coarse sand conditions and improving soil permeability under fine sand conditions. 1, CE particles have a cellular porous structure and have certain water absorption, so it can improve the water retention of soil. 2.CE particles are cellular porous structures with certain gaps, so it can improve the permeability and drainage of soil.

Although CE can adjust the soil water content in the whole environment, watering should still follow the principle of small amount and multiple times, especially in summer or dry autumn, and attention should be paid to keeping the surface sand and roots moist, and the watering times are not limited, only 3 ~ 6 times a day. The watering time should be at night or early morning, during which the wind is not strong, the humidity is high and the temperature is low, which can reduce the evaporation of water. If you irrigate at noon, half of the water will evaporate before it reaches the ground, so water should avoid the strong sunshine at noon. However, excessive humidity often leads to lawn diseases. Irrigation at night will make lawn grass wet for a long time, and make the protective layer such as wax layer on the surface of lawn plants thinner, so pathogenic bacteria and microorganisms can easily enter and spread into plant tissues, so early morning is the best time for lawn irrigation. Water should be poured thoroughly, not flooded. Each watering should be limited to the surface layer, and no water flow will be formed. Generally, water should be allowed to penetrate to 15 to 20 cm. When watering, the sprinklers should be set to Mao Mao rain, so as to avoid excessive water drops affecting the surface of the green.

Irrigation plays an important role in keeping green. How to irrigate the grassland so that it is not short of water, too high humidity will not lead to bacterial reproduction, but also maintain the air permeability of the soil. This should be treated comprehensively, not just by soil improvers. Therefore, if there is no problem with irrigation, we can only master the irrigation methods and use products that regulate the soil environment, such as CE green conditioner, to achieve comprehensive improvement and focus on governance.

A new technology to fill the blank of green maintenance technology was born.

Fertilization plays a very important role in regulating the nutrient content of lawn soil. How to make fertilizer play its greatest role without losing element content is very worthy of our in-depth thinking and discussion. In addition, mowing the lawn is particularly important for the maintenance of the lawn. The following is a detailed introduction to lawn fertilization and pruning.

The green lawn is planted on sand-based lawn, and the fertility of the lawn bed is poor. Most of the mixed peat and other basic fertilizers are lost due to leaching. How to protect fertilizer and prevent its loss is very important. Ce green conditioner has strong corrosion resistance, inertia and hydrophilicity, so fertilizer particles, soil and water are closely combined because of CE particles, which can effectively reduce the loss of nutrients and have a good effect on fertilizer conservation. In general, green lawns need a lot of fertilizers, and the demand for nitrogen fertilizer in the first year is more than that in the next few years. Combined with CE green conditioner, it can effectively reduce the amount of fertilizer and play a great role in saving fertilizer.

Fertilization on the green needs to combine time and season. When planting green lawn, the first fertilization should be about 2.5 cm in height, mainly nitrogen fertilizer, 3 grams per square meter, and then every 10 ~ 15 days, with the application rate of 3 grams per square meter/kloc-0 ~. Under normal circumstances, pure nitrogen fertilizer and complete fertilizer should be applied alternately, complete fertilizer can be applied in combination with punching in spring and autumn, and nitrogen fertilizer is usually used as topdressing. The total fertilizer is mainly available fertilizer with high nitrogen, high phosphorus and low potassium, and the ratio of nitrogen, phosphorus and potassium is 5: 3: 2.

According to the dosage form of fertilizer and the needs of lawn grass, there are usually four fertilization methods: spraying, spreading, strip application and acupoint application. Artificial fertilization or mechanical fertilization usually divides the fertilizer into two parts, half horizontal and half vertical. Sand can also be mixed when the amount of fertilization is small, so that fertilization is more uniform. CE green conditioner can be mixed with fertilizer, which can effectively improve fertility. Fertilization is best carried out when the seedlings are dry to prevent fertilizer particles from sticking to the leaves of the seedlings and causing burns. Water immediately after fertilization to avoid fertilizer burning seedlings. Fertilization should be continued in the young turf stage of the green until it becomes turf.

Lawn mowing is not only for the beauty of lawn and the optimization of court sports, but also a science and an art, and the parameters such as the timing and length of lawn mowing are very particular. The following is a detailed introduction of lawn mowing precautions.

When the planted green lawn begins to tiller, it can be trimmed. The first mowing should be carried out when the lawn grass coverage rate reaches above 90% and the seedling height is 10 ~ 15cm. Pruning should be carried out when there is no dew, and the height of grass cutting should be initially controlled at 8 ~ 12cm, and then gradually reduced to the required height. For creeping glume cutting, the suitable stubble height is 0.5 ~ 1.5cm, and the grass height is cut off 1/3 each time. The frequency of mowing was originally 1-2 times a week, and should be increased to once a day with the completion of green lawn. In order to let the lawn recuperate, the stadium with too much business often chooses to close for half a day or one day in a week, on which the lawn can be mowed. After the green is covered with sand, it rains continuously, and the grass grows slowly or stops growing in winter. Mowing should be carried out in a certain direction and trajectory. Generally, the first knife should be pointed at the flagpole, cut straight through the hole cup to the green circle, turn around and press the edge of the first knife a little, and continue to cut the second knife until the green is cut in half, and the other half is cut in the opposite direction to the first knife. After mowing the grass in a straight line, cut off the leaking grass around the edge of the green 1 to 2 weeks to make the guolingcao more flat. Cutting grass repeatedly in the same place and direction for a long time is easy to produce texture on the lawn. Lawn mower should carry a grass collecting device when cutting grass, and the grass clippings left on the lawn will affect the quality of the lawn. Lawn grass pruning is also related to its trampling resistance. CE has strong mechanical strength and can adjust the compactness of lawn. It can be spread on the lawn surface to adjust the compactness of the lawn without affecting the lawn viewing and dripping.

The third new technology to fill the blank of green maintenance technology was born.

Pest control is a headache in lawn maintenance. Diseases may occur in any period of lawn growth, and once they occur in a large area, it is difficult to control. Therefore, it is what our lawn maintenance managers can do to control the disease in as small a range as possible.

Comprehensive maintenance skills are as follows:

1. Don't apply too much nitrogen fertilizer on lawn: especially in hot summer, try to apply less or no nitrogen fertilizer. Too much nitrogen fertilizer will reduce the disease resistance of lawn grass, but a certain amount of nitrogen fertilizer should be maintained to improve the stress resistance of lawn.

2. Adjust the amount of watering: Most of the pathogens causing lawn diseases are sensitive to water, and they grow actively when there is much water and the soil is wet, which is easy to cause diseases.

3. Dewing: Dewing the green lawn in time every morning can reduce the occurrence of diseases.

4. Reduce straw mats: avoid the accumulation of thick straw mats on the green. Too thick straw mat layer is not only conducive to the breeding of diseases, but also absorbs some fungicides and increases the dosage of fungicides.

5. Create a growth condition with good ventilation and less shade: under the condition of poor ventilation and shade, the air on the green is too humid, and the plants are tender and juicy, which may easily lead to a large number of diseases.

6. Disease prevention: Before the arrival of the hot and humid climate in summer, a certain amount of fungicides should be sprayed regularly to prevent diseases.

All of the above are effective methods to reduce the occurrence of diseases, through which diseases can be controlled in the smallest occurrence range. There is also an effective way to control the occurrence and development of diseases, that is, to use ce green conditioner. ce green conditioner has electricity and hydrophilicity on CE surface, which can be beneficial to the fixed growth of microorganisms and the formation of biofilm, and play a great role in controlling the propagation of fungi in soil, thus controlling lawn diseases.

Introduction of other lawn maintenance measures and methods:

Rolling can smooth the surface of the green and help to press the twigs into the soil, so watering before rolling is better. The number of rolling depends on the density and smoothness of the green, and once a week is more suitable. The roller can use single-line or three-line dynamic rolling to ensure uniform pressure. Manual rolling is not advisable, it will leave many footprints on the green.

During the construction of the green, the surface of the green is rough and uneven due to human factors, the erosion caused by uneven watering during maintenance and management, and the small pits caused by the impact of excessive water drops on the soil surface. Sand covering can solve this problem. If the grass grows to the height that can be trimmed, mowing before covering the sand is more conducive to the settlement and uniform dragging of the sand. Every time the sand is covered, it is done with a sand covering machine, and then the surface is leveled with an iron trawl or a plastic net.

Perforation is an effective method to solve turf hardening. When the soil is hardened, the grass roots need to be irrigated and the underground pests are controlled, holes can be drilled. There are three kinds of perforated pipes: hollow, solid and middle opening. According to the purpose of the green, holes are usually drilled two or three times a year, with a depth of 4.6 to 10.2 cm and a diameter of 5 to 15 mm. With holes, water, gas, fertilizer, pesticides and the like can easily enter the root layer and promote the healthy growth of the lawn. Perforation can be combined with the application of CE green conditioner, which can effectively control the permeability of lawn soil, control soil hardening and control the formation of green and black soil layer.
