Description

Technical Field

[0001] This invention relates to a method for replacing lawns, and more particularly to how to effectively remove existing lawns and fix new lawns within a certain area. Background Technology

[0002] Generally, replacing a lawn involves digging up the existing lawn, disposing of the excavated lawn as waste, cleaning up the excavated area, and then planting and managing the new lawn.

[0003] However, lawns managed in this way can harden in rainy or difficult-to-manage conditions, and the lawn can disappear. In this case, if it rains, drainage will fail, other areas will become waterlogged, and management becomes extremely difficult.

[0004] In addition to poor soil drainage, hardening of the soil can lead to the chronication of pathogens that may grow on the lawn due to the effects of the shrinking and shrinking confrontation layer over the years.

[0005] Furthermore, current lawn replacement methods primarily involve manual or mechanical clearing and tree planting. However, these methods can easily damage the transplanted lawn during the clearing process, leading to uneven growth after establishment. Additionally, the lack of effective methods for treating the cleared lawn and soil can place a burden on the environment.

[0009] The problem that the invention aims to solve

[0010] The problem this invention aims to solve is to effectively remove existing turf during turf replacement and to provide a method for promoting the survival of new turf and improving the growing environment.

[0011] The subject matter of this invention is not limited to the subject matter mentioned above, and other unmentioned technical subject matter can be clearly understood by the owner from the following description.

[0012] means for solving problems

[0013] To address the aforementioned challenges, a method for replacing lawns according to an example includes the following steps: identifying the area requiring lawn replacement; first patching the area requiring lawn replacement; second patching the area requiring lawn replacement; spraying the herbicide on the area requiring lawn replacement; performing a switching operation on the second patched area; replacing the lawn and the byproducts of the lawn replacement work using the completed area; and using the lawn replacement and the byproducts required for the lawn replacement. The method also includes a surface preparation stage, spraying fertilizer on the area requiring lawn replacement to help the lawn establish itself early, and planting turf rafts in the area requiring lawn replacement. This includes a stage of leveling the turf rafts by rolling after planting, and a stage of sandblasting and watering the area after the rolling operation.

[0014] The steps for determining the area where the lawn needs to be replaced include: using a drone to photograph the location where the lawn needs to be replaced, using Pix4Dmapper to perform 3D mapping, calculating the data of the area where the lawn needs to be replaced, analyzing the data of the area where the lawn needs to be replaced, and calculating the project area.

[0015] The first trimming phase of the area where the lawn needs to be replaced includes a phase of cutting the lawn in the area where the lawn needs to be replaced, a phase of spraying herbicides in the area where the lawn needs to be replaced may include a phase of spraying a first herbicide around the manholes located in the area where the lawn needs to be replaced, and a phase of spraying a second herbicide in areas outside the area where the lawn needs to be replaced.

[0016] The first herbicide can be mixed with 100 parts by weight of water to a ratio of 20 to 30 parts by weight of glacial acetic acid, 0.8 to 1.5 parts by weight of wood vinegar, and 0.2 to 0.8 parts by weight of pre-adhesive.

[0017] The second herbicide can be mixed in the following proportions: 100 parts by weight of water, 0.1 to 0.4 parts by weight of the non-selective herbicide General, 0.25 to 1 part by weight of urea fertilizer, 0.5 to 2 parts by weight of forage liquid, and 0.125 to 0.5 parts by weight of pre-admixture.

[0018] The step of performing a second trimming on the area where the lawn needs to be replaced after spraying the herbicide may include removing any remaining roots and debris and cleaning the surface after spraying the herbicide on the area where the lawn needs to be replaced.

[0019] The fertilizer comprises soluble phosphate fertilizer and rice fermentation extract. The rice fermentation extract is obtained through a rice core preparation stage and a stage of extracting the rice fermentation extract from the rice core. In the rice core preparation stage, japonica rice is pulverized into 35-40 mesh, steamed at 80-88°C for 60-70 minutes, cooled, and then 30-50 parts of water are added to 100 parts by weight of the steamed rice flour. Fermentation is carried out at 43-47.5°C, and the rice is extracted with Ascobacterium. Rice at 33-47.5°C is inoculated during fermentation. The water extraction stage involves saccharifying 100 parts by weight of the rice core at 45-48°C for 8-9 hours, then adding 300-370 parts by weight of malt extract to the first saccharification liquid and saccharifying at 60-65°C for 2-5 hours. This may include a stage of inactivating the saccharification liquid at 95-100°C for 5 minutes and then cooling it, as well as a stage of filtering impurities through a sieve to obtain the rice fermentation extract from the rice core.

[0020] The first herbicide, for 100 parts by weight of water, may be composed of 20 to 30 parts by weight of glacial acetic acid, 0.8 to 1.5 parts by weight of wood vinegar, 0.2 to 0.8 parts by weight of pre-adhesive, 1 to 4 parts by weight of salt, 2 to 4 parts by weight of baking soda, 15 to 17 parts by weight of lemon juice, 4 to 5 parts by weight of onion juice, 1 to 3 parts by weight of cinnamon, 15 parts by weight of lemon juice, and parts by weight of turmeric and ginger.

[0021] The steps for performing the switching operation in the second trimming area may include cleaning the surface to remove residual byproducts after the second trimming is completed in the area where the lawn needs to be replaced.

[0022] The stage of using a tractor to mix the remaining turf and soil in the area where the cleanup work has been completed with the area where the turf needs to be replaced may include a stage of using a tractor to evenly mix the remaining turf and soil to create an environment where the turf can easily survive.

[0023] Specific details of other embodiments are included in the detailed description and drawings.

[0024] Invention Effects

[0025] According to the method for making a lawn replacement method in one embodiment, the lawn replacement area and its surrounding conditions can be accurately measured, guiding the lawn to survive as soon as possible.

[0026] The effects of the implementation examples are not limited to those above; this list includes many more different effects. Attached Figure Description

[0027] Figure 1 This is a flowchart of a lawn replacement method according to one embodiment. Detailed Implementation

[0028] The advantages and features of this invention, as well as the methods for implementing them, will become clear from the accompanying drawings and detailed implementation examples. However, this invention will be embodied in different forms and is not limited to the embodiments described below. These embodiments are intended only to complete the introduction of the invention and to fully inform those skilled in the art of the scope of the invention, which is defined only by the scope of the claims.

[0029] Figure 1 This is a flowchart of a lawn replacement method according to one embodiment.

[0030] like Figure 1 As shown, a lawn replacement method according to one embodiment includes: determining the area where the lawn needs to be replaced (S10); performing a first maintenance on the area where the lawn needs to be replaced (S20); spraying a herbicide on the area where the lawn needs to be replaced (S30); performing a second maintenance on the area where the lawn needs to be replaced after spraying the herbicide (S40); performing the spraying operation (S50); clearing away the remaining replacement lawn and the soil from the replacement lawn using a tractor (S60); clearing away lawn byproducts (S70); and spraying the lawn using a tractor (S80). Therefore, it may include a stage to help the lawn establish itself early (S90), a stage of planting lawn rafts (S100), a stage of leveling the lawn after planting the lawn rafts by rolling (S110), and a stage of watering after sandblasting (S120).

[0031] In one implementation example, the step (S10) of identifying areas where lawn needs to be replaced might be the step of determining the areas where lawns need to be replaced at the location where lawns are currently in place. For example, this could be the stage of detecting areas where lawns need to be replaced at locations where lawns are being replaced (golf courses, football fields, parks, cemeteries, etc.). The stage of identifying areas where lawns need to be replaced can be performed manually or by using drones, etc.

[0032] For example, if drones are used to identify areas where turf needs replacement, the process might include using drones to photograph the location before construction, performing 3D mapping using Pix4Dmapper, calculating data for the area requiring replacement, analyzing this data, and calculating the project area. Historically, inaccurate project area measurements have led to numerous errors in cost calculations, especially on golf courses where uneven terrain results in discrepancies between the actual area measured and the actual area to be replaced. Therefore, this process can be prevented. Data for the area requiring turf replacement might include area, terrain, and flatness.

[0033] In one example, the first trimming of the area where the lawn needs to be replaced (S20) may include a stage of cutting the lawn in a specific area to less than 4 cm, defining the area where the lawn needs to be replaced. This clearly defines the boundary between the area where the lawn needs to be replaced and the surrounding area. In other embodiments, the first trimming of the area where the lawn needs to be replaced (S20) may include a stage of trimming the border of a specific area to less than 4 cm, defining the area where the lawn needs to be replaced.

[0034] In one embodiment, the stage (S30) of spraying herbicide in the area where the lawn needs to be replaced may include a stage of spraying a first herbicide in the area around the manholes located in the area where the lawn needs to be replaced and a stage of spraying a second herbicide in the area outside the area where the first herbicide was sprayed.

[0035] In one embodiment, the stage of spraying a first herbicide around a manhole in an area where lawn replacement is needed may be a stage where an environmentally friendly first herbicide is sprayed into the area around the manhole, taking into account the possibility that the herbicide is injected into the manhole and discharged into wastewater. Here, the first herbicide may include water, glacial acetic acid, wood vinegar, and a pre-adhesive. For example, the first herbicide can be mixed with 100 parts by weight of water to a ratio of 20 to 30 parts by weight of glacial acetic acid, 0.8 to 1.5 parts by weight of wood vinegar, and 0.2 to 0.8 parts by weight of pre-adhesive.

[0036] Electrocolorants can be at least one of nonionic surfactants, anionic surfactants, cationic surfactants, coconut oil, and soybean oil.

[0037] Even if this first-class herbicide flows into manholes, it can minimize groundwater pollution. In addition, because it contains glacial acetic acid, the high acidity of which can kill weeds, the herbicide is acidic and has a small molecular weight, which makes it easier and more readily absorbed by the glacial acetic acid.

[0038] In one embodiment, the stage of spraying the second herbicide in areas other than those where the first herbicide was sprayed may be the stage of spraying the second herbicide in areas where lawn replacement is required, excluding the area around manholes. Here, the second herbicide may be a different herbicide from the first herbicide.

[0039] The second herbicide may include water, a non-selective herbicide, urea fertilizer, forage liquid, and a pre-admixture. For example, the second herbicide can be mixed in the following proportions: 100 parts by weight of water, 0.1 to 0.4 parts by weight of the non-selective herbicide, 0.25 to 1 part by weight of urea fertilizer, 0.5 to 2 parts by weight of forage liquid, and 0.125 to 0.5 parts by weight of the pre-admixture.

[0040] Non-selective herbicides may include glyphosate ammonium (36%) and oxyfluorfen (2%).

[0041] Urea fertilizer can reduce the surface tension and pH of herbicide solutions, enhance adhesion, and increase weed control effectiveness.

[0042] The pre-silking agent can be the same as the pre-silking agent of the first herbicide.

[0043] Mixing urea fertilizer, forage liquid, and pre-admixture into this second herbicide can improve the absorption rate of the herbicide after spraying, shorten the absorption time, and reduce the amount of herbicide used.

[0044] When wood vinegar is mixed with herbicides, it can reduce the amount of herbicide used, increase herbicide absorption, and reduce the actual amount of herbicide used by about 20%.

[0045] This second herbicide can shorten the herbicide absorption time, thereby shortening the lawn's dead period and the overall construction period.

[0046] In one embodiment, the step (S40) of performing a second trimming of the area where the lawn needs to be replaced after spraying the herbicide may include removing any remaining roots and debris and cleaning the surface after spraying the herbicide on the area where the lawn needs to be replaced.

[0047] In a real-time example, the step (S50) of performing the switching operation may include cleaning the surface to remove residual byproducts after the second trimming is completed in the area where the lawn needs to be replaced.

[0048] In one example, the stage (S60) of using a tractor to mix and replace the remaining lawn and soil in an area may include a stage of using a tractor to uniformly mix the remaining lawn and soil to create an environment where the lawn is easy to grow.

[0049] In other embodiments, the step (S60) of replacing the remaining lawn and soil in an area with a tractor-mixed lawn may include replacing the remaining lawn and soil in the area with a tractor-mixed lawn after the cleanup work has been completed. The stage (S60) of replacing the remaining lawn and soil in an area with a tractor-mixed lawn may include a stage of spraying an additive into the soil and a stage of mixing the remaining lawn and soil.

[0050] Here, additives may include rice water. Additionally, additives may include purified water and olive oil. For example, additives may be mixed with 100 parts by weight of purified water to a ratio of 30 to 40 parts by weight of rice water and 2 to 4 parts by weight of olive oil.

[0051] In one implementation example, the step (S70) of removing lawn by-products from the surface of the lawn replacement area may include installing a rake on a golf course tractor to collect and destroy the by-products (leaves, stems, roots, turf).

[0052] The problem in the past was that when trees were planted on turf rafts after pesticides were sprayed, the trees were prone to ring blight and ragiper blight after the turf was constructed, even if the trees were contaminated with pesticides or absorbed organic matter.

[0053] This invention utilizes a rake-type device to remove only surface byproducts (excluding soil), which can reduce organic matter and prevent disease outbreaks after lawn planting.

[0054] In one embodiment, the step (S80) of preparing the surface of the lawn replacement area may include a step of evenly preparing the planting material surface of the lawn replacement area to help the lawn survive.

[0055] In one embodiment, the stage (S90) of promoting early lawn survival through fertilization may include spraying fertilizer in the lawn replacement area before planting. The fertilizer may be a basic slag phosphate or a soluble phosphate (FMP). For example, spraying 40-50 g / m² of basic slag phosphate or soluble phosphorus phosphate in the lawn replacement area before planting may be a stage that promotes lawn root growth. Similarly, spraying fertilizer in the lawn replacement area before planting can increase the growth rate of the planted lawn roots.

[0056] In one embodiment, the step of planting turf rafts (S100) may include precisely planting the newly prepared turf rafts into the turf replacement area. Here, a turf raft refers to turf with roots cut into pieces of a certain size.

[0057] In one instance, the stage (S110) of flattening the turf raft by rolling after planting may include a stage of firmly fixing the turf raft and homogenizing its surface by rolling.

[0058] In a real-time example, the stage (S120) of watering the area after sandblasting the completed rolling operation may include the stages of sandblasting to improve soil permeability and watering to induce survival.

[0059] In other embodiments, the first herbicide may include water, glacial acetic acid, wood vinegar, a pre-adhesive, salt, baking soda, lemon juice, onion juice, cinnamon oil, and turmeric powder. For example, the first herbicide, for 100 parts by weight of water, may be a mixture of 20 to 30 parts by weight of glacial acetic acid, 0.8 to 1.5 parts by weight of wood vinegar, 0.2 to 0.8 parts by weight of the pre-adhesive, 1 to 4 parts by weight of salt, 2 to 4 parts by weight of baking soda, 15 to 17 parts by weight of lemon juice, 4 to 5 parts by weight of onion juice, 1 to 3 parts by weight of cinnamon, and parts by weight of turmeric.

[0060] Salts, under osmotic pressure, can induce dehydration and water loss in plant cells. Fermented baking soda, being alkaline, inhibits weed growth. Citric acid lowers the pH and damages weed cell walls. Onion juice has strong antibacterial properties, and lemon juice, being acidic, is effective in disrupting weed cell walls. Cinnamon oil helps inhibit weed growth. Notably, turmeric powder contains curcumin and terpenoids, which can effectively inhibit plant cell division and suppress weed growth.

[0061] Turmeric powder can be obtained through the stages of soaking turmeric roots, drying turmeric roots, maturing and drying turmeric roots, and crushing mature turmeric roots.

[0062] In one embodiment, the turmeric root inoculation stage may include a stage of inoculating the turmeric root with groundwater after washing it. The soaking stage may include immersing the washed turmeric root in soaking water at 5°C to 10°C for 30 to 50 minutes. In this case, the soaking water can be mixed with 100 parts by weight of purified water in the following proportions: 5 to 10 parts by weight of lemon juice, 2 to 3 parts by weight of vinegar, 8 to 9 parts by weight of rice water, and 1 to 2 parts by weight of salt. Soaking the turmeric root in this water will make it highly acidic, thereby inducing cell destruction and water evaporation on the surface of the weed, resulting in rapid weed death. The rice water can be obtained by soaking the first batch of washed rice in rice water for 6 to 15 minutes. Here, the rice water soaking water may include purified water, milk, olive oil, and honey. For example, rice water can be mixed with 100 parts by weight of purified water to make a ratio of 8 to 10 parts by weight of milk, 2 to 4 parts by weight of olive oil, and 3 to 5 parts by weight of honey.

[0063] In one embodiment, the drying stage of turmeric root may include drying the turmeric root that has completed the impregnation stage at 50°C to 60°C for 6 to 8 hours.

[0064] In one experiment, the maturation process of dried turmeric roots could include the following stages: injecting turmeric essential oil into the dried turmeric roots; forming gas spots in the turmeric roots injected with turmeric essential oil; injecting a first additive into the gas spots; forming a second additive on the outer surface of the turmeric roots; maturation stage; and drying stage.

[0065] The process of injecting turmeric root with turmeric oil can include injecting the oil into the root using a turmeric oil syringe or similar method. Turmerone and zerone are components with strong antibacterial and insecticidal properties.

[0066] The stage of pore formation on turmeric roots infused with hemp oil likely involves the formation of multiple pores with a diameter of 0.1 mm to 0.5 mm on the outer surface of the turmeric root. These pores can form cylindrical grooves with a depth of 0.3 mm to 1.5 mm on the outer surface of the turmeric root.

[0067] The stage of injecting the first additive into the valve is the stage of injecting the first additive into the valve formed by turmeric root. The first additive may include cinnamon extract, licorice extract, and sake. For example, the first additive, for 100 parts by weight of cinnamon extract, can be mixed in a ratio of 20 to 25 parts by weight of licorice extract and 3 to 5 parts by weight of sake. Such a first additive can enhance the sweetness and flavor of turmeric root.

[0068] The stage of coating the outer surface of turmeric root with a second additive may involve applying the second additive to air pockets and the entire outer surface of the turmeric root. The second additive may include coconut oil, aloe vera gel, and lemon juice. For example, for 100 parts by weight of coconut oil, the second additive may be mixed in a ratio of 60 to 80 parts by weight of aloe vera gel and 3 to 5 parts by weight of lemon juice.

[0069] The maturation stage may be the stage in which the turmeric root, after completing the second additive stage of coating, matures at 2-8°C for 1-3 hours.

[0070] The drying stage may include drying mature turmeric roots at 45°C to 50°C for 8 to 12 hours.

[0071] In one embodiment, the stage of crushing turmeric root after completing the maturation process may include a stage of cutting the turmeric root into pieces of 1-3 cm in size, and a stage of crushing the cut turmeric root into powder using a mixer.

[0072] Here, coconut oil, soybean oil, acacia black, and pine resin powder can be mixed together. For example, the pre-coating agent can be mixed with 100 parts by weight of coconut oil, 30 to 40 parts by weight of soybean oil, 5 to 8 parts by weight of acacia black, and 8 to 12 parts by weight of pine resin powder.

[0073] In other embodiments, the fertilizer may comprise a soluble phosphate fertilizer and a rice fermentation extract. For example, for every 100 parts by weight of the soluble phosphate fertilizer, the fertilizer may be mixed with 5 to 8 parts by weight of the rice fermentation extract. The rice fermentation extract contains various amino acids, organic acids, vitamins, minerals, and beneficial bacteria, which can promote turf root growth and increase turf immunity while increasing beneficial bacteria in the soil.

[0074] Rice fermentation extracts may include the steps of preparing rice cores and extracting rice fermentation extracts from the rice cores. The steps of preparing rice cores may include grinding japonica rice into 35–40 meshes, steaming it at 80–88°C for 60–70 minutes, cooling it, adding 30–50 g of water to 100 g of the steamed rice flour, inoculating it with 2.8–4.7 g of Aspergillus oryzae strain, and fermenting it at 33–35°C for 40–43 hours.

[0075] The process of extracting rice fermentation extract from rice cores may include saccharifying 100 parts by weight of rice cores at 45-48°C for 8-9 hours, then adding 300-370 parts by weight of malt extract to the first saccharification liquid and saccharifying at 60-65°C for 2-5 hours, deactivating the saccharification liquid at 95-100°C for 5 minutes and then cooling it, and filtering impurities through a sieve to obtain the rice fermentation extract.

[0076] The embodiments of the present invention have been illustrated above with reference to the accompanying drawings. However, those skilled in the art will understand that the invention can be implemented in other specific forms without altering the technical concept or essential features of the invention. Therefore, the embodiments described above should be understood as exemplary in all aspects, and not limiting.
