Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of lawn maintenance and renovation, and particularly relates to a maintenance method for golf course lawn. BACKGROUND

[0002] In suitable areas, the service life of golf course lawn is generally about 15 years (in humid climate). In northern courses, there is a closed period of nearly one month every winter as a lawn maintenance period, in order to enable the lawn to safely survive the cold winter, a layer of fine sand (generally river sand, about 2mm thick) needs to be laid on the lawn.

[0003] With the continuous operation of the course, the lawn is affected by factors such as sand and soil self-settling, personnel trampling and equipment rolling, and accumulates day by day, which easily causes the soil and root system of the lawn to gradually compact, and the produced clay layer and dead grass layer will isolate the infiltration of water and nutrients, so that the roots cannot be supplied accordingly, which is not conducive to the growth of the lawn, and when the rainy season comes, the lawn cannot drain quickly, and a series of diseases will also be produced. Therefore, in order to improve the lawn maintenance standard and prolong the service life of the lawn, the lawn needs to be regularly "relaxed and invigorated".

[0004] The maintenance method of general course lawn is combing, puncturing and punching, etc. These conventional methods can only maintain the basic lawn, and cannot maintain the deeper soil and root system of the lawn. The lawn maintained by the conventional method has slow regreening, poor air permeability and poor disease resistance, so the effect is poor.

[0005] Therefore, how to more quickly and low-cost maintain the deep soil and root system of the lawn to ensure that the lawn reaches an excellent state and improve the member satisfaction is an urgent problem to be solved for most courses.

[0006] Furthermore, the demand for river sand for course sanding in winter is large, and the standard is high. The best sand is 40-60 mesh sand. In recent years, the exploitation of river sand has been strictly limited due to the destruction of ecological environment, and the price is high and the procurement is difficult; sea sand has high corrosiveness and is not suitable for use in course maintenance lawn; artificially mined mechanism sand has a rough surface and high friction, which is easy to compact and is also not suitable for course sanding. However, course sanding is the key to lawn maintenance. After the course is sanding every year, the sand will slowly sink to the root of the lawn, resulting in a large amount of sand in the root of the lawn. How to recycle the sand in the root of the lawn is also an urgent problem to be solved for most courses. SUMMARY

[0007] To solve the above problems, the application provides a golf course lawn maintenance method. The soil layer is loosened horizontally and vertically, the water and air permeability of the lawn is enhanced, the decomposition of the residual fertilizer and organic matter in the sand is accelerated, the damage of excessive fertilization to the soil is avoided, and the breeding of diseases and pests is reduced. The turned old sand can be recycled and reused, the sand usage is saved, and the green energy-saving and environmental protection purposes are achieved. During the sand turning process, the maintenance personnel carefully checks the growth of the lawn roots, timely prevents and disposes the diseases, and formulates a targeted maintenance plan in combination with the factors such as illumination, slope and drainage.

[0008] The technical scheme of the application is as follows:

[0009] A golf course lawn maintenance method comprises the following steps:

[0010] (1) basic pruning process: the entire lawn is subjected to basic pruning, the height of the fairway after pruning is 0.8-1 cm, and the height of the half-long grass area after pruning is 2-4 cm; the grass clippings are cleaned up;

[0011] (2) sand turning process:

[0012] S1, according to the depth of the sand layer, the depth of the sand turning is determined;

[0013] S2, before the sand turning operation, water is uniformly poured on the fairway, the water is poured to the extent that the moisture of the root system can last for 3-5 days, so that the soil and the sand layer can be ensured to have sufficient water, and the lawn can be prevented from being dead due to the failure of timely watering and air drying after special operation;

[0014] S3, the sand turning is performed by using a sand turning machine, the sand turning machine has four layers of three different blades to jointly complete the sand turning, the first layer of small circular blades first shallowly cuts the lawn, the depth is 2-4 cm, and the interval is 7-9 cm; the second layer of large circular blade type blades deeply cuts the lawn, the depth is 7-10 cm, and the interval is 12-17 cm; the third layer of hook type blades deeply penetrates the deeply cut lawn, and the hook type blades turn the deep sand, grass clippings and grass roots to the surface of the lawn; the fourth layer of blades is the same as the first layer, and the lawn is shallowly cut again, the gap of the third layer is treated, the cutting, turning and gap treatment are completed in one step, and finally the bottom sand of the lawn is turned out;

[0015] (3) sand collecting process: after the sand turning, a large amount of grass clippings, grass roots and fine sand are mixed together on the surface of the lawn, the grass clippings, grass roots and sand are separated, and the sand is completely disinfected and sterilized; and then the sand is directly settled to the root part of the lawn;

[0016] (4) subsequent process

[0017] R1, after the sand turning, the lawn is subjected to watering and rolling operation once; the watering is poured in one time and penetrates the lawn.

[0018] Apply fertilizer appropriately after R2 rolling to improve maintenance results;

[0019] Finally, R3 applies insecticides and fungicides for a comprehensive spraying operation to ensure the health of the lawn.

[0020] Preferably, there are 5 small round blades, with a distance of 26 cm between the blades; 5 large round blades, with a distance of 28 cm between the blades; and 6 hook-shaped blades, with a distance of 25 cm between the blades.

[0021] Preferably, before the basic mowing process, it is ensured that the lawn is free of pests and diseases. If pests and diseases are present, special maintenance work cannot be carried out. The lawn should be treated with insecticides before the maintenance work can be carried out to avoid spreading pests and diseases to other areas.

[0022] Preferably, during the sand-turning process of S3, the sand-turning machine should be kept traveling in a straight line and should not turn to avoid damaging the turf with the blades or causing the lawn to lift up; at the same time, ensure that there are no stones or hard objects on the lawn before turning to avoid damaging the blades.

[0023] Preferably, the specific process of the sand collection step is as follows:

[0024] L1 exposes grass clippings, grass roots, and fine sand to the sun to dry them, allowing the grass clippings and grass roots to lose moisture and making it easier to separate them from the sand. At the same time, it thoroughly disinfects and sterilizes the sand.

[0025] After L2 is exposed to the sun, a trawler is attached to the back of the transport vehicle. The trawler's drag force is used to separate the grass clippings, grass roots, and sand. The separated sand settles directly to the base of the lawn. The remaining dried grass clippings are collected using a combination of manual labor and a grass vacuum. Finally, the lawn is cleaned manually.

[0026] Preferably, R2 fertilization requires the application of organic fertilizer to improve soil structure and promote lawn growth.

[0027] Beneficial effects of the present invention

[0028] Following the above procedures, lawn maintenance can remove thatch, alter soil structure, loosen the soil and root system, expand root growth space, promote deeper root growth, and increase water and aeration, thus helping to prevent diseases. This results in a healthier and stronger lawn. Attached Figure Description

[0039] II. Material Preparation and Staffing

[0040] 1. One set of sand turning machine blades (alloy tip)

[0041] 2. Fuel

[0042] 3. Insecticides, fungicides, and organic fertilizers

[0043] 4. One trawl net

[0044] 5. Six iron shovels

[0045] 6. 15 large brooms

[0046] 7. Personnel: 25 people, including 5 machine operators and 20 cleaning workers. (Estimated construction period: 5 days for an 18-hole course)

[0047] Example 1

[0048] Shandong Wenlv Guyun Lake International Golf Course, built in 2003, has a total grass area of ​​approximately 200,000 square meters, including fairways, driving ranges, and activity centers. The course has been covered with sand annually, with a layer of approximately 0.7 cm thick each winter. Over time, this sand layer has reached 18 cm, resulting in uneven fairways and severe waterlogging during the rainy season, causing significant damage to the turf. The deeper soil layers have reached a point where they need resurfacing. In the winter of 2021, fairways 14 and 15 were selected for a sand layer resurfacing experiment. Fairway 14 was no longer covered with sand but instead underwent the sand resurfacing process using this invention. Fairway 15, however, continued with the traditional maintenance method, with a 0.7 cm layer of fine sand. The implementation steps are as follows:

[0049] 1. Basic pruning procedures

[0050] 1.1 Before carrying out special maintenance on the lawn, the entire golf course lawn needs to be mowed. The height of the fairway after mowing should be 0.8-1cm, and the height of the semi-rough area after mowing should be 2-4cm.

[0051] 1.2 After mowing, remove all grass clippings manually or by using a grass vacuum.

[0052] 1.3 Ensure the lawn is free of pests and diseases before maintenance. If pests and diseases are present, special maintenance work cannot be carried out. The lawn should be treated with insecticides before maintenance can proceed to avoid spreading pests and diseases to other areas.

[0053] 2. Breaking the sand-turning process

[0054] 2.1 Determine the depth of the cut and sand turning. Before turning the sand on the fairway, first select 6-10 points evenly on the fairway and use a soil sampler to sample the sand layer under the turf. Based on the depth of the sand layer, determine the depth of the cut and sand turning to be approximately 10cm-13cm.

[0055] 2.2 Watering. Before turning the sand, water the fairway evenly until it is 50% soaked, and keep the roots moist for 3-5 days to ensure that the soil and sand layer have sufficient moisture and prevent the lawn from drying out and dying due to lack of water after the special operation.

[0056] 2.3 Scraping and Turning the Grass. A specialized grass-turning machine is used for scraping and turning the grass. The machine has four layers of three different types of blades working together. The first layer consists of 12 small round blades, which make shallow cuts in the grass, creating 12 scratches about 3cm deep and spaced about 8cm apart. The second layer consists of 5 large round blades, which make deeper cuts in the grass, creating 5 scratches about 7-10cm deep and spaced about 15cm apart. The third layer consists of 5 hook-shaped blades, which penetrate deep into the grass and use their hook shape to turn the deep sand, grass clippings, and grass roots to the surface. The fourth layer consists of small round blades, which are the same as the first layer, making shallow cuts in the grass again and closing the gaps left by the third layer. The entire scraping, turning, and closing process is completed in one go, successfully turning the sand from the bottom layer of the grass.

[0057] 2.4 Before cutting and turning the sand, ensure there are no stones or hard objects. During operation, keep the sand-cutting and turning machine moving in a straight line and do not turn.

[0058] 2.5 Use a tractor to drive machinery for sand-breaking and turning operations.

[0059] 3. Sand collection process

[0060] 3.1 After turning the sand, expose the lawn surface, which contains a large amount of grass clippings, grass roots, and fine sand, to the sun for a day.

[0061] 3.2 After sun exposure, a trawl net is attached to the back of the transport vehicle. The trawl net's drag force is used to separate the grass clippings, grass roots, and sand. The separated sand settles directly to the base of the lawn. The remaining dried grass clippings are collected using a combination of manual labor and a grass vacuum.

[0062] 3.3 Finally, the lawn is cleaned up manually.

[0063] 4. Subsequent processes

[0064] 4.1 After turning the sand, water and roll the lawn once. Water thoroughly at once; timely watering not only accelerates sand settling but also facilitates rolling and improves the smoothness of the lawn.

[0065] 4.2 Apply fertilizer appropriately after rolling to improve the maintenance effect.

[0066] 4.3 Finally, use insecticides and fungicides to carry out a comprehensive spraying operation.

[0067] Following the above procedures, lawn maintenance can remove thatch, alter soil structure, loosen the soil and root system, expand root growth space, promote deeper root growth, and increase water and aeration, thus helping to prevent diseases. This results in a healthier and stronger lawn.

[0068] This embodiment 1 describes a lawn maintenance method consisting of four steps, taking five days. One year after maintenance, the lawn exhibits a well-developed root system and fewer pests and diseases, demonstrating significant effectiveness. See attached images showing the lawn's growth before and after maintenance. Figures 1-6 :

[0069] Based on the data comparison and analysis in the above embodiments, the annual sand laying requirement for a standard 18-hole golf course is approximately 1200 tons. At a price of 300 yuan per ton, the annual sand laying cost is approximately 380,000 yuan (360,000 yuan for sand and 20,000 yuan for machinery and labor). Using this invention costs only 65,000 yuan, as detailed in the table below:

[0070] Budget details

[0071]

[0072] It is evident that applying this invention to a standard 18-hole golf course can save more than 300,000 yuan.

[0073] Therefore, this invention is an innovation in turf maintenance technology. It requires little investment, has a short working period, low cost, and excellent results. It is the best measure for improving the quality of golf course operations and reducing costs and increasing efficiency for enterprises. It has great guiding significance for the entire golf course turf maintenance technology.

[0074] Example 2

[0075] The Shandong Wenlv Guyun Lake International Golf Course, built in 2003, has a total grass area of ​​approximately 200,000 square meters, including fairways, driving ranges, and activity centers. The course has been gradually covered with sand each year, with an annual sand layer of about 0.7 cm. Over the years, the sand layer has reached a thickness of 18 cm, resulting in uneven fairways and severe waterlogging during the rainy season, causing significant damage to the turf. The deeper soil layers have entered a period of regeneration. In the winter of 2022, fairways 10 and 11 were sampled for sand layer regeneration experiments, using this invention. The implementation steps are as follows:

[0076] 1. Basic pruning procedures

[0077] 1.1 Before carrying out special maintenance on the lawn, the entire golf course lawn needs to be mowed. The height of the fairway after mowing should be 0.8-1cm, and the height of the semi-rough area after mowing should be 2-4cm.

[0078] 1.2 After mowing, remove all grass clippings manually or by using a grass vacuum.

[0079] 1.3 Ensure the lawn is free of pests and diseases before maintenance. If pests and diseases are present, special maintenance work cannot be carried out. The lawn should be treated with insecticides before maintenance can proceed to avoid spreading pests and diseases to other areas.

[0080] 2. Breaking the sand-turning process

[0081] 2.1 Determine the depth of the cut and sand turning. Before turning the sand on the fairway, first select 8-10 points evenly on the fairway and use a soil sampler to sample the sand layer under the turf. Based on the depth of the sand layer, determine the depth of the cut and sand turning to be approximately 10cm-13cm.

[0082] 2.2 Watering. Before turning the sand, water the fairway evenly until it is 50% soaked, and keep the roots moist for 3-5 days to ensure that the soil and sand layer have sufficient moisture and prevent the lawn from drying out and dying due to lack of water after the special operation.

[0083] 2.3 Scraping and Turning the Grass. A specialized grass-turning machine is used for scraping and turning the grass. The machine has four layers of three different types of blades working together. The first layer consists of 12 small round blades, which make shallow cuts in the grass, creating 12 scratches about 3cm deep and spaced about 8cm apart. The second layer consists of 5 large round blades, which make deeper cuts in the grass, creating 5 scratches about 7-10cm deep and spaced about 15cm apart. The third layer consists of 5 hook-shaped blades, which penetrate deep into the grass and use their hook shape to turn the deep sand, grass clippings, and grass roots to the surface. The fourth layer consists of small round blades, which are the same as the first layer, making shallow cuts in the grass again and closing the gaps left by the third layer. The entire scraping, turning, and closing process is completed in one go, successfully turning the sand from the bottom layer of the grass.

[0084] 2.4 Before cutting and turning the sand, ensure there are no stones or hard objects. During operation, keep the sand-cutting and turning machine moving in a straight line and do not turn.

[0085] 2.5 Use a tractor to drive machinery for sand-breaking and turning operations.

[0086] 3. Sand collection process

[0087] 3.1 After turning the sand, expose the lawn surface, which contains a large amount of grass clippings, grass roots, and fine sand, to the sun for a day.

[0088] 3.2 After sun exposure, a trawl net is attached to the back of the transport vehicle. The trawl net's drag force is used to separate the grass clippings, grass roots, and sand. The separated sand settles directly to the base of the lawn. The remaining dried grass clippings are collected using a combination of manual labor and a grass vacuum.

[0089] 3.3 Finally, the lawn is cleaned up manually.

[0090] 4. Subsequent processes

[0091] 4.1 After turning the sand, water and roll the lawn once. Water thoroughly at once; timely watering not only accelerates sand settling but also facilitates rolling and improves the smoothness of the lawn.

[0092] 4.2 Apply fertilizer appropriately after rolling to improve the maintenance effect.

[0093] 4.3 Finally, use insecticides and fungicides to carry out a comprehensive spraying operation.

[0094] Following the above procedures, lawn maintenance can remove thatch, alter soil structure, loosen the soil and root system, expand root growth space, promote deeper root growth, and increase water and aeration, thus helping to prevent diseases. This results in a healthier and stronger lawn.
