Description

Technical Field

[0001] The present invention belongs to the field of golf course green lawn maintenance, and particularly relates to a green lawn repair agent, its preparation and use method, and a repair kit. Background Art

[0002] Due to reasons such as ball mark impact, mechanical damage, pests or diseases in the green area of a golf course, local lawn depressions or bald patches often occur, seriously affecting the smoothness and visual effect of the green. The industry generally uses the method of filling yellow sand after squeezing with a green fork to restore the surface smoothness. However, this method can only temporarily repair the depression, the formation of the lawn's self-healing tissue is slow, the repair cycle is long, and the color of the filler often cannot be fully matched with that of the natural lawn, resulting in a visual disorder problem. Summary of the Invention

[0003] In view of the above technical problems, the present invention provides a green lawn repair agent, its preparation and use method, and a repair kit. The repair agent is composed of yellow sand, a functional dye, water-retaining peat soil, creeping bentgrass seeds, etc. according to a specific mass fraction ratio. It can not only seamlessly match the color of the green lawn surface visually, but also promote the rapid germination of grass seeds through the high water retention of peat soil. Combining the "green sand" aggregate formed by the dye and yellow sand, it realizes the rapid repair and nutrient supply of the damaged lawn area, thereby greatly improving the repair efficiency and shortening the lawn self-healing cycle.

[0004] According to a first aspect of the present invention, there is provided a green lawn repair agent, which comprises by mass fraction:

[0005] 100 parts of yellow sand;

[0007] 1 - 5 parts of peat soil;

[0008] 0.1 - 0.5 parts of creeping bentgrass seeds.

[0009] As a preferred solution, the yellow sand has the following particle size distribution: >2mm 0%, >1mm 15%, >0.5mm 37%, >0.3mm 30%, >0.1mm 15%, <0.1mm 3%; and / or,

[0010] The dosage of the dye is adjusted as follows according to the season: 0.080 - 0.090 parts in spring, 0.090 - 0.100 parts in summer, 0.100 - 0.110 parts in autumn, and 0.080 - 0.090 parts in winter; and / or,

[0011] The content of wood fiber in the peat soil is not less than 20wt%; and / or,

[0012] The creeping bentgrass seeds are a mixture of two creeping bentgrasses, PeenA1 and PeenA4.

[0013] As a preferred embodiment, the mass ratio of the peat soil to the creeping bentgrass seeds is 10:1 to 20:1.

[0014] As a preferred embodiment, it further contains 0.1 - 5wt% of a nutrient additive, and the nutrient additive is selected from at least one of humic acid and organic fertilizer.

[0015] According to the second aspect of the present invention, a method for preparing a putting green lawn repair agent is further provided, which is applicable to the preparation of the above-mentioned putting green lawn repair agent, and includes the following steps:

[0016] Step A: Mix an appropriate amount of yellow sand and a coloring agent in a mixing device to obtain colored aggregate;

[0017] Step B: Mix an appropriate amount of peat soil and creeping bentgrass seeds in the mixing device to obtain an organic premix;

[0018] Step C: Mix the colored aggregate obtained in Step A and the organic premix obtained in Step B in the mixing device to obtain the putting green lawn repair agent.

[0019] As a preferred embodiment, before Step C, the colored aggregate obtained in Step A is sun-dried until the water content ≤ 12% or dried by a low-temperature drying device until the water content ≤ 12%;

[0020] In Step B, first sun-dry the weighed peat soil until the water content ≤ 12% or dry it by a low-temperature drying device until the water content ≤ 12%, and then mix it with the creeping bentgrass seeds.

[0021] According to the third aspect of the present invention, a method for repairing a putting green lawn is further provided, using the above-mentioned putting green lawn repair agent or the putting green lawn repair agent prepared by the above-mentioned preparation method, and includes the following steps:

[0022] Fill the putting green lawn repair agent into the lawn damage area at 0.8 - 1.2 times the volume equivalent to the damaged area;

[0023] Keep the area moderately moist after application, and make a supplementary application once after 7 - 14 days according to the recovery situation.

[0024] As a preferred embodiment, the moistening method is to irrigate 1 - 2 times a day, and keep the surface soil moist but not waterlogged each time.

[0025] According to the fourth aspect of the present invention, there is further provided a putting green lawn repair kit, including the yellow sand component, the dye component, the peat soil component, the creeping bentgrass seed component prepared as described above, and a supporting mixing instruction manual.

[0026] As a preferred solution, the kit further includes:

[0027] A mixing and stirring bucket with a capacity of 20L;

[0028] A graduated watering can;

[0029] A gardening spade for on-site application.

[0030] The present invention adopts the above technical solutions and has at least the following beneficial effects:

[0031] 1. The putting green lawn repair agent of the present invention has significant advantages in visual matching. By premixing yellow sand and a functional dye in a specific ratio to obtain colored aggregate, after repair, the color of the "green sand" seamlessly connects with the surface color of the surrounding putting green lawn, and without additional spraying or covering treatment, the overall beauty of the golf course can be maintained, avoiding visual disorder caused by traditional yellow sand filling.

[0032] 2. The repair agent of the present invention is particularly outstanding in water retention and promoting callus formation. The selected peat soil is rich in lignin fibers and has excellent water absorption and water retention capabilities, which can build a stable water environment in the repair area, reduce surface water evaporation, and promote the rapid formation and growth of grass seeds and damaged lawn callus tissue, significantly shortening the lawn self-healing cycle.

[0033] 3. By introducing creeping bentgrass seeds, the present invention realizes the function of quickly replanting damaged areas. The grass seeds are evenly distributed in the peat - grass seed premix, and the seeds are wrapped and protected by a high water retention matrix. Under the cover of "green sand", they can germinate quickly and grow towards the surrounding lawn. The connectivity between the repair area and the natural putting green lawn is good, further improving the repair effect and the overall consistency of the lawn.

[0034] 4. The preparation method of the present invention is simple and easy to implement, suitable for on-site operation. Only need to mix each component in proportion in a common mixing device, without special instruments or complex processes, and the mixing conditions (rotation speed, time, etc.) can be flexibly adjusted according to the characteristics of on-site raw materials, facilitating the rapid preparation and application by golf course maintenance personnel.

[0035] 5. The repair agent of the present invention has multiple functions: it can not only fill in the depression and restore the surface flatness, but also color-match the lawn color, provide seeds and nutrient matrix, and release slow-release water and nutrients through peat soil, realizing an integrated repair of "filling, coloring, cultivating, and nourishing", significantly improving the quality and efficiency of lawn repair.

[0036] 6. All components used in the present invention are environmentally friendly and safe materials. The selected yellow sand, peat soil and grass seeds are strictly screened and do not contain heavy metals or harmful chemical substances; the dye is non-toxic and harmless to humans, livestock and the environment, meeting the ecological maintenance requirements of golf courses, and ensuring no environmental risks during the repair process and subsequent use.

[0037] 7. The present invention has good adjustability and versatility. The dosage of the dye can be flexibly adjusted within the range of 0.08 - 0.11 parts according to seasons or the depth of lawn color; the ratios of peat soil to grass seeds, and colored aggregates to premixes can also be appropriately optimized according to different climates, soil qualities and repair requirements, and are widely applicable to the maintenance and repair of various golf greens and lawns in different areas.

[0044] The technical solutions in the present invention will be clearly and completely described below in conjunction with specific embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0045] Embodiment 1 (Preferred Embodiment)

[0046] (I) Material Preparation

[0047] After screening the clean fresh river sand, make its particle size ratio meet the requirements of the following table:

[0048] Particle size (mm) >2 >1 >0.5 >0.3 >0.1 <0.1 Ratio (%) 0 15 37 30 15 3

[0049] Select the product GRIGG GREENPIG produced by Gregg Company in the United States, which does not contain heavy metals or other chemical components harmful to lawns, humans, animals and the environment.

[0050] Air-dry the peat soil with a high content of wood fiber and sieve it through an 8-mesh sieve for standby.

[0051] Crawling bentgrass (Peen A1+A4) grass seeds (select the same variety as the putting green lawn of this course).

[0052] (2) Compound ratio

[0053] Yellow sand: 100 parts.

[0054] Dye: 0.095 parts (using Grigg Greenpig, a harmless water-soluble dye), pre-mixed and diluted with 200 mL of clear water.

[0055] Peat soil: 2.3 parts (wood fiber content is about 25 wt%)

[0056] Crawling bentgrass seeds: 0.2 parts (Peen A1∶PeenA4 = 1∶1)

[0057] (3) Equipment and pretreatment

[0058] Use an industrial vertical flat-mouth mixer or a on-site portable electric mixer, and set the rotation speed to 30 r / min.

[0059] Pre-dry the yellow sand and peat soil at room temperature until the water content ≤ 12%. Keep the grass seeds dry.

[0060] (4) Preparation steps

[0061] Step A: Put 100 parts of air-dried yellow sand and 0.095 parts of the diluted dye into the mixer, stir at 30 r / min for 4 minutes to obtain colored aggregate ("green sand"), take it out and air-dry for standby. This "green sand" is as Figure 1 shown.

[0062] Step B: Put 2.3 parts of air-dried peat soil and 0.2 parts of crawling bentgrass seeds into the same mixer, stir at 30 r / min for 4 minutes to obtain an organic premix. The mixed organic premix is as Figure 2 shown.

[0063] Step C: Add the mixtures obtained in Step A and Step B to the mixer according to the mass ratio of 100∶2.5 (colored aggregate∶organic premix), stir at 30 r / min for 4 minutes to prepare the final repair agent, as Figure 3 shown.

[0064] (5) Application method

[0065] Fill the obtained repair agent into the golf ball mark or mechanical damage area, and the filling amount is 1.0 times the damaged volume. Refer to Figure 4 and Figure 5 for the comparison diagrams before and after filling.

[0066] After application, keep the area irrigated once a day, and keep the surface soil slightly moist. After about 7 days, the grass seeds germinate and integrate with the surrounding lawn.

[0067] Example 2 (Seasonal adjustment)

[0068] Formula adjustment

[0069] Same as Example 1, the dosage of the dye is changed to: 0.085 parts in spring, 0.095 parts in summer, 0.15 parts in autumn, and 0.09 parts in winter.

[0070] The ratio of peat soil, grass seeds, and yellow sand is the same as that in Example 1.

[0071] Preparation and application

[0072] The mixing steps are the same as those in Example 1.

[0073] Since the lawn color is darker in summer and autumn, a higher dosage of the dye can obtain a deeper "green sand" effect; in spring and winter, the dye is reduced accordingly to ensure a natural color.

[0074] Example 3 (Containing nutritional additives)

[0075] Formula composition

[0076] On the basis of Example 1, additionally add 2wt% of humic acid or organic compound fertilizer (calculated based on the total mass).

[0077] Ratio: 100 parts of yellow sand, 0.095 parts of dye, 2.3 parts of peat soil, 0.2 parts of grass seeds, and 2 parts of nutritional additives.

[0078] Preparation steps

[0079] Steps A and B are the same as those in Example 1;

[0080] Step C: Add the colored aggregate, organic premix, and 2 parts of nutritional additives into the mixer at the same time, and stir at 30 r / min for 5 minutes until uniform.

[0081] Effect

[0082] Humic acid and organic fertilizers can slowly release soil nutrients, promote the root development of grass seeds, and improve the survival rate of seedlings.

[0083] Example 4 (On-site portable equipment and proportion fine-tuning)

[0084] Equipment

[0085] On-site, an electric portable small mixing bucket (with a capacity of 20L and adjustable rotation speed of 20–40r / min) is used.

[0086] Ratio and method

[0087] The ratio of colored aggregate to organic premix can be adjusted to 95∶5 to enhance water retention, or 110∶1 to strengthen color coverage.

[0088] For example, take 95 parts of colored aggregate and 5 parts of organic premix, stir at 30r / min for 3 minutes to obtain the repair agent.

[0089] Application

[0090] Using the measuring cup and gardening shovel provided in the kit, it can be quickly prepared and filled on-site, suitable for small-scale immediate repair.

[0091] Example 5 (multiple grass seeds)

[0092] Grass seed substitution

[0093] Except for Peen A1 / A4, it can be replaced with single strains of Bermuda grass, creeping bentgrass or other mow-resistant creeping grass seeds, and the grass seed ratio of 0.1–0.5 parts remains unchanged.

[0094] Effect comparison

[0095] The germination rates of different grass seeds vary under different climates, and can be adapted according to the common varieties of local putting green lawns to obtain the best repair effect.

[0096] In the above embodiments, the rotation speed, time and ratio range used in each step can be appropriately fine-tuned according to on-site conditions; the raw material brands, particle sizes, water contents and equipment models used are only preferred examples, and all equivalent technical solutions should be covered within the protection scope of the present invention.

[0097] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
