Description

Technical Field

[0001] The invention relates to the field of pet products, in particular to a lightweight natural grass pet blanket and a preparation method thereof. Background Art

[0002] With the rapid development of society, more and more people are raising pets as life companions and spiritual sustenance. According to the "2021 China Pet Industry White Paper" (consumption report) guided by the Pet Industry Branch of the China Animal Husbandry Association and produced by the Paidu Pet Industry Big Data Platform, the number of dogs and cats in China's urban households reached 112.35 million in 2021, including 54.29 million pet dogs and 58.06 million pet cats; the size of the entire urban dog and cat market reached 249 billion yuan, a year-on-year increase of 20.6%, of which the pet dog market size was 143 billion yuan, a year-on-year increase of 21.2%, and the pet cat market size was 106 billion yuan, a year-on-year increase of 19.9%.

[0003] Playing and exercising are the nature of pets such as dogs and cats. While satisfying the spiritual needs of their owners, pets raised at home need proper exercise every day to release physical energy and feel happy in order to maintain the physical and mental health of pets. For example, pet dogs, such as Huskies, need a certain amount of exercise every day, otherwise they will tear up furniture and even tear down the house. Walking the dog outdoors is the main way for pet dogs to exercise and play, but most of the community green spaces are currently managed in an extensive manner, and there may be problems with pests and diseases and excessive pesticide residues on outdoor lawns. Pet dogs are at risk of parasite infection and pesticide poisoning when exercising and playing in green spaces. In addition, different pets playing and exercising in the same green space also greatly increases the risk of cross-infection of diseases between pets. Pet cats are relatively independent in character and are not suitable for outdoor exercise and play. They are generally kept indoors for a long time, so they have almost no contact with the natural environment. Long-term isolation from nature and the busyness of their owners who have no time to accompany them may cause pet cats to suffer from depression, lack of exercise, sudden weight gain, constipation and other problems, which are all important causes of pet cats' illness.

[0004] There are many types of pet blankets and mats on the market, mainly made of plastic, PVC, Oxford cloth, cotton cloth, etc. As pets use them for a long time, they will breed a large number of bacteria and produce odors, which seriously damage the home environment. In addition, the cleaning effect of artificial pet mats is poor, and the odor is basically impossible to eradicate. Artificial pet mats cannot meet the needs of pets for a natural environment. At present, there are no natural grass pet blankets in the pet market. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a natural grass pet blanket which is green, ecological, simple in structure, light in overall weight and easy in daily maintenance.

[0006] The purpose of the present invention is to reduce the probability of pets getting diseases due to lack of contact with nature, and to reduce the burden of pet owners raising pets in all aspects. The present invention simulates outdoor natural scenes by placing a natural grass pet blanket in a sunny area indoors, takes advantage of the pet's natural yearning for nature, and uses the fresh smell of grass to induce the pet to exercise and play, defecate, etc. on the natural grass pet blanket, while meeting the needs of pets to eat grass to aid digestion and expel hairballs. The present invention solves the problems of pet dogs taking outdoor walks every day, being inconvenient to take outdoor walks under extreme weather conditions (heavy rain, heavy snow, high temperature, cold waves, etc.), young and old dogs being unsuitable for outdoor walks, and pet cats being kept indoors and unable to contact nature.

[0029] A natural grass pet blanket is composed of a plurality of the above-mentioned lightweight natural grass pet blankets, wherein the plurality of the above-mentioned lightweight natural grass pet blankets are connected by natural splicing or connecting pieces.

[0030] The method for using the lightweight natural grass pet blanket comprises the following steps:

[0031] (A) The container cover of the natural grass pet blanket is placed on the container during transportation, and the container cover is removed before use. During use, it is kept or placed under the container, and the container cover is placed on the outside of the container with the opening facing upward. The natural grass pet blanket is placed on a horizontal surface in a balcony, living room, windowsill, corridor, courtyard, etc. where sunlight can reach, and is exposed to sunlight for 2 hours or more per day;

[0032] (B) When the pet is a young or small pet, tear off or fold down a portion of the area along the pre-creased perforated lines on the side walls of the bottom plate and the top plate to facilitate the pet's access and use, and keep the torn portion properly;

[0033] (C) Maintenance: Spray a small amount of tap water regularly to keep the natural grass at an appropriate humidity. Spray 500-600ml of tap water on the natural grass of each natural grass pet blanket every 3-5 days. The feces excreted by the pet on the natural grass pet blanket must be removed promptly, and the residual feces on the natural grass must be sprayed off with a spray bottle. If the pet dog defecates on the natural grass pet blanket, tear off part of the area along the pre-creased perforated line on the side wall of the top plate, and fold the torn part 120 degrees along the folding line (with the folding line exposed) to form a V-shaped feces picker, and use the V-shaped feces picker to pick up the feces in time.

[0034] (D) Trimming: Fold the torn-off side wall of the bottom plate downward by 90 degrees along the trimming height mark line, with the length scale line exposed upward, and the centers of the two torn-off strips overlapped, and the distances were adjusted to form an X-shaped trimming aid. The four bottom ends of the X-shaped trimming aid were simultaneously placed at the roots of the natural grass, and the grass carpet shears were used to trim the natural grass accurately and neatly along the horizontal surface of the X-shaped trimming aid with the scale lines;

[0035] The natural grass has different mowing height marking lines according to the grass species: 3-6cm for tall fescue, 3-5cm for perennial ryegrass, 2-5cm for bluegrass, 2-4cm for centipedegrass, 1-4cm for zoysiagrass, and 1-3cm for bermudagrass.

[0036] (E) Arrangement: tear off a portion of the area along the toothed perforated lines on the side wall of the bottom plate to expose the saw teeth to form a grass clipping cleaner. After the natural grass is trimmed, the grass clipping cleaner is used to comb the trimmed grass leaves out of the grass carpet to prevent the trimmed grass leaves from contaminating the pet carpet and the indoor environment;

[0037] (F) Update: When the natural grass pet blanket has been used for a period of time and the grass has withered and yellow spots are severe, put the container cover on the container, discard the natural grass pet blanket as a whole, and replace it regularly; when discarding the natural grass pet blanket, put the container cover back on the container with the opening facing downward to avoid spilling natural grass or pet excrement during the process of discarding the natural grass pet blanket. The through holes are used for handholding when the natural grass pet blanket is moved or discarded.

[0038] The lightweight natural grass pet blanket of the present invention is different from the prior art in that:

[0039] The lightweight natural grass pet blanket of the present invention can be discarded as a whole after being used for a period of time, and can be replaced regularly. It has the advantages of being green and ecological, simple in structure, lightweight as a whole, and easy in daily maintenance.

[0040] The smell and texture of the natural grass in the lightweight natural grass pet blanket of the present invention can attract pets. After several times of guidance, pets can quickly adapt to playing and exercising on the pet blanket, lying quietly and resting. The pet blanket provides a green ecological place exclusively for pets indoors, and can realize the function of walking dogs and cats indoors when the owner is too busy to take care of the pets or it is inconvenient to go out due to bad weather. Pets can nibble on the natural grass, which helps pet cats expel hair balls and clean their stomachs. At the same time, the lawn pet blanket provides a natural toilet for pets.

[0041] The lightweight natural grass pet blanket of the present invention has a simple structure, a small overall height, a stable structure after being placed, and is not easy to tip over, so it is convenient for pets to get on and off. The pet blanket is light in weight, easy to transport, move, discard and replace, and the grass can grow normally if it is exposed to sunlight for 2 hours or more every day. It can be discarded as a whole after a period of use and replaced with a new pet blanket. The present invention does not require operations such as rinsing and dumping urine after the pet urinates, and daily maintenance saves time and effort.

[0042] The fermented pine bark, fermented sawdust, fermented peanut shell, fermented rice husk, coconut bran and the like used in the soil-free and sand-free process of the present invention are agricultural and forestry production wastes, which have a wide range of sources and low costs;

[0043] The soilless substrate of the present invention has a reasonable root structure, the lower growth substrate layer has high organic and inorganic nutrient content, good water absorption and water retention, and large-particle substrate root support, which can provide sufficient moisture, nutrients and support requirements for natural grass; the middle root reinforcement layer is a degradable high-strength mesh cloth, which provides a strong connection for the natural grass roots to form a sponge-like structure; the upper stem base protection layer is a loose, soft, resilient and adsorbent organic substrate, which can effectively protect the stem base structure of natural grass under the stress of long-term playing and lying of pets, provide the natural grass pet blanket with playability, and absorb odors produced by indoor pets at the same time;

[0044] The agricultural and forestry waste used in the soilless substrate of the present invention can be degraded and utilized during the use of the natural grass pet blanket, providing a large amount of nutrients for the natural grass, reducing the amount of fertilizer applied during the growth of the natural grass, and having the characteristics of environmental protection and emission reduction;

[0045] Compared with soil, the agricultural and forestry waste used in the soilless matrix of the present invention is more effective in preventing and controlling insect eggs, pests, and pathogens. The planting method that is effectively isolated from the ground further reduces the invasion of ground and underground pests and pathogens.

[0046] The agricultural and forestry wastes used in the soilless substrate of the present invention are all materials with low bulk density, no industrial heavy metal ions and dust. The natural grass root structure is relatively thin (2-5 cm), and has the characteristics of light weight compared with soil and sand-based substrates of the same thickness. The pet blanket is light and labor-saving when mailing, moving indoors, and regularly replacing; the substrate does not contain industrial heavy metal ions and dust particles, reducing or even avoiding the risk of indoor pollution.

[0047] The planting tray used in the preparation method of the present invention can effectively control the size of the natural grass pet blanket, avoiding the problem of partial root loss when the natural grass roots grow deep in the soil and the substrate laid on the soil, and root damage caused by cutting the edges of the grass roots, thereby ensuring that the quality of the pet blanket is not reduced when it is mailed to the user's residence and can be used as soon as it arrives;

[0048] Experiments have shown that compared with the prior art, the root structure layer of the present invention can ensure that the natural grass is less affected by the stress of pets playing and lying under the same pet playing and lying intensity, and the quality of the natural grass pet blanket can be restored quickly after the pets stop playing and lying.

[0049] The product prepared by the method of the present invention has the characteristics of good grass recovery growth after pets play, easy transportation, low cost, non-toxic and harmless.

In winter, a natural grass pet blanket with a size of 60cm*40cm (length*width) is selected, with a substrate thickness of 2.5cm and natural grass selected from meadow bluegrass. The natural grass pet blanket is placed on the windowsill, and sunlight can shine through the window to the grass blanket from 11:00 to 15:00. The Singapore cat exercises and plays on the grass blanket every day, lies quietly in the sun, and the urine produced by occasional urination is absorbed and used by the grass. After occasional defecation, the feces are cleaned up in time, and the residual feces on the grass leaves are sprayed with a spray bottle.

[0093] The natural grass of the natural grass pet blanket is sprayed with 500-600 ml of tap water every 5-7 days and can be used for 15-30 days. The natural grass of the natural grass pet blanket is Kentucky bluegrass. When it grows to 5-6 cm, use the X-shaped trimming aid 6 and the grass blanket shears 7 to trim the natural grass. After trimming, the natural grass stubble height is 3-4 cm. The cut grass leaves are cleaned up with the grass clippings cleaner 5. When the grass is severely withered and yellowed, the container cover 4 is put back on the container 1, and the natural grass pet blanket is discarded as a whole. A new natural grass pet blanket can be replaced on a specified date or time interval.

[0094] Example 7

[0095] Maine Coon Pet Blanket

[0096] Maine Coons weigh 6 to 9 kilograms and are relatively large. In summer, two natural grass pet blankets are connected together. The overall size is 80cm*60cm (length*width), the substrate thickness is 2.5-3cm, and the natural grass is a 6:4 mixed sowing of perennial ryegrass and meadow bluegrass. The natural grass pet blanket is placed on the balcony floor, and sunlight can shine through the window to the grass from 11:00 to 13:00. Maine Coons exercise and play on the grass blanket every day, lie quietly in the sun, and the urine produced by occasional urination is absorbed and utilized by the grass. After occasional defecation, the feces are cleaned up in time, and the residual feces on the grass leaves are sprayed with a spray bottle.

[0097] The natural grass of each natural grass pet blanket unit is sprayed with 500-600ml of tap water every 3-5 days, and can be used for 15-25 days. When the natural grass perennial ryegrass and meadow bluegrass of the natural grass pet blanket grow to 4-7cm, use the X-shaped trimming aid 6 and the grass blanket shears 7 to trim the natural grass. After trimming, the natural grass stubble height is 3-5cm, and the cut grass leaves are cleaned up with the grass clippings cleaner 5. When the grass is severely withered and yellowed, put the container cover 4 back on the container 1, and the natural grass pet blanket is discarded as a whole, and can be replaced with a new natural grass pet blanket on a specified date or time interval.

[0148] 1. Comparative test of matrix formula

[0149] The experiment was conducted in the greenhouse of the Tongzhou planting base of the Chinese Academy of Forestry from March 15 to May 15, 2022. The temperature was set to a constant temperature of 20°C and the light time was 12h. The experiment was carried out in a seedling tray with an inner diameter of 52cm, a width of 26cm and a height of 8cm. 16 small holes with a diameter of 2mm were evenly punched on the bottom of the tray. First, a layer of 20g / ㎡ non-woven fabric was laid on the bottom, and then a matrix combination with a thickness of 30mm was laid. There were 9 treatments in total, as shown in Table 1. Each treatment was repeated 5 times. The matrix was paved and watered to the set thickness. The tall fescue variety was wonderful: the meadow bluegrass variety was sapphire = 8:3 (mass ratio) was sprinkled on the surface of the matrix. The sowing density of tall fescue was 40g / ㎡, and the sowing density of meadow bluegrass was 15g / ㎡. A layer of coarse sand (thickness 1-2mm) was sprinkled on the seeds to cover the seeds. Spray water every day to keep the matrix moist, and no fertilizer or pruning is done during the period.

[0152] Measurement indicators and methods

[0153] Seedlings emerged on the 5th day after sowing, and samples were taken 55 days after emergence. Three representative trays were selected from the 5 trays to measure relevant indicators. The height, color, density and other indicators of natural grass were first measured or scored, and then samples were taken to measure indicators such as biomass and root system.

[0154] The specific method is as follows:

[0155] For the height of natural grass, measure 30 plants in each tray, take the average, and measure with a ruler to the nearest mm.

[0156] The color of natural grass is determined by visual inspection based on the color grade of natural grass from withered yellow to dark green: dark green to dark green 7-9 points, light green to darker green 5-7 points, more green with a few dead leaves 3-5 points, more dead leaves with a little green 1-3 points, dormancy or withered yellow 1 point.

[0157] Natural grass coverage refers to the percentage of the vertical projection area of ​​the natural grass to the land surface area. It is measured by the needle puncture method, that is, samples are selected for puncture statistics, and the ratio of the number of times the needle tip contacts the natural grass to the total number of sample points is used as the coverage index.

[0158] The uniformity of natural grass is scored on a 9-point scale using visual inspection, with 9 points indicating completely uniformity, 6 points indicating uniformity, and 1 point indicating significant differences.

[0159] For natural grass density, a grass block of 10×10 cm was randomly selected from each tray, and the number of natural grass plants in the small sample was counted and the average value was taken.

[0160] For underground biomass, randomly select one grass block of 10 cm × 10 cm from each tray, cut off the stems and leaves on the natural grass substrate, rinse the roots with clean water, dry at 80 °C for 24 hours, weigh the mass with a balance, and take the average value.

[0161] Data processing

[0162] SPSS19.0 software was used to process and analyze the measurement data, and Excel2020 software was used for data statistics and mapping.

The underground biomass of treatment 9 is the largest, and the underground biomass of treatment 6 is the smallest, and the underground biomass of treatments 8 and 9 is significantly greater than that of treatments 6 and 7.

[0174] Test conclusion:

[0175] In the mixed matrix combination containing coconut bran, treatments 4 and 5 were better than treatments 1, 2, and 3 in natural grass color, height, coverage, uniformity, and underground biomass. Treatment 3 was poor in coverage, uniformity, and underground biomass. Treatment 4 was significantly better than treatment 5 in natural grass color, density, and underground biomass. Treatments 1 and 2 were combinations of coconut bran and vermiculite in different proportions. They performed averagely in natural grass color, height, and density. The possible reason was that a large proportion of coconut bran had high salt content and EC value, which was not conducive to the growth of natural grass. Treatment 3 was a combination of coconut bran, fermented sawdust, and vermiculite. The natural grass coverage, uniformity, and density were the worst. The reason for this was that the sawdust was hard and difficult to decompose, which took a long time. There may be incomplete fermentation of sawdust and a high C / N ratio, which seriously affected the growth of natural grass. The natural grass in treatments 4 and 5 performed well in terms of color, height, coverage, and uniformity. The possible reason is that there are different proportions of fermented peanut shells in the substrate combination. Peanut shells are soft in texture and easy to quickly decompose during the fermentation process. After decomposition, they are fluffy and porous, which is conducive to root growth and can provide sufficient nutrients for the growth of natural grass. In summary, the mixed substrate combination of treatment 4 is suitable for the planting of natural grass pet blankets.

[0176] Among the organic substrate combinations containing peat, treatments 8 and 9 were superior to treatments 6 and 7 in natural grass color, height, coverage, and underground biomass, and treatment 9 was significantly superior to treatment 8 in natural grass color and coverage. Treatment 6 was a single peat, and the natural grass color, height, coverage, and underground biomass were all poor. The possible reason was that the pH value was low and it was not suitable for natural grass growth. Treatment 7 was a combination of peat and fermented rice husk substrates, and the natural grass grew generally. Treatments 8 and 9 added fermented peanut shells to the substrate of treatment 7, and the natural grass color, height, coverage, and underground biomass were superior to treatment 7. The possible reason was that peanut shells were easy to decompose and were fluffy and porous after fermentation. The combination with peat and fermented rice husks could improve the physical and chemical properties of the substrate such as pH value, EC value, and porosity, which was suitable for natural grass growth and could provide sufficient nutrients for natural grass growth. In summary, the organic substrate combination of treatment 9 is suitable for planting natural grass pet blankets.

[0177] 2. Matrix structure comparison test:

[0178] Experimental site, materials and methods:

[0179] Experimental site: Greenhouse of Tongzhou planting base of Chinese Academy of Forestry.

[0180] Experimental materials: On August 20, 2022, the tall fescue variety Miaoxiang and the meadow bluegrass variety Sapphire with strong resistance were selected and mixed in a mass ratio of 8:3. The sowing density of tall fescue was 40g / ㎡, and the sowing density of meadow bluegrass was 15g / ㎡.

[0181] The structure of the natural grass pet blanket is: grass seed protection layer, grass seed layer, stem base protection layer, root reinforcement net, growth matrix layer, and planting tray.

[0182] The grass seed protection layer is 10g / ㎡ white non-woven fabric, which is covered with the grass seed layer after sowing.

[0183] The stem base protective layer is a mixture of fermented peanut shells, fermented rice husks and peat in a volume ratio of 3:3:4. The peanut shells and rice husks are piled and fermented in advance.

[0184] The root reinforcement net is a degradable mesh cloth made of cotton with a pore size of 17.8mm.

[0185] The growth matrix layer is made by mixing coconut bran, fermented pine bark, fermented sawdust and vermiculite in a volume ratio of 3:2:2:3. The pine bark and sawdust are pre-screened to remove larger particles and dust. The pine bark particle size is 3-8mm, the sawdust particle size is 6-12mm, and they are pre-fermented. The coconut bran particle size is 0-6mm, and the vermiculite particle size is 3-6mm.

[0186] The planting tray is made of PVC, with holes at the bottom, and is 60*40*6cm in length, width and height.

[0187] Experimental design

[0188] A randomized block experiment design was adopted, and the area of ​​the plot was 0.24㎡. The experiment set up 6 root structure combination treatments: Treatment 1 was a growth matrix layer of 26mm + root reinforcement layer + stem base protection layer of 14mm + grass seed layer + grass seed protection layer; Treatment 2 was a growth matrix layer of 20mm + root reinforcement layer + stem base protection layer of 10mm + grass seed layer + grass seed protection layer; Treatment 3 was a growth matrix layer and stem base protection layer evenly laid in a volume ratio of 2:1 (thickness 40mm) with a built-in root reinforcement net + grass seed layer + grass seed protection layer; Treatment 4 was a growth matrix layer and stem base protection layer evenly laid in a volume ratio of 2:1 (thickness 30mm) with a built-in root reinforcement net + grass seed layer + grass seed protection layer; Treatment 5 was a sand-based matrix with a thickness of 40m with a built-in root reinforcement net + grass seed layer + grass seed protection layer;

[0189] Four replicates were set up for each treatment, of which three replicates used an adult weighing 50 kg to step on the pets to simulate pets playing and lying down. Each treatment was stepped on evenly for 1 minute at 9 am and 2 pm every day. The treatment started on September 15 and ended on September 24, with a total of 10 stepping treatments. Then normal maintenance was resumed for 12 days (September 25 to October 6). One replicate was the control (no stepping). During the stepping treatment and the recovery of maintenance, the indicators were measured every two days, and each measurement time was 3 pm.

[0190] Indicator measurement method

[0191] The color of the stems and leaves of natural grass was determined by visual inspection and scored according to the color grade of natural grass from withered yellow to dark green: dark green to dark green 7-9 points, light green to darker green 5-7 points, more green with a few withered leaves 3-5 points, more withered leaves with a little green 1-3 points, dormancy or withered yellow 1 point.

[0192] The height of natural grass stems and leaves was measured with a ruler.

[0193] Natural grass coverage refers to the percentage of the vertical projection area of ​​the natural grass to the land surface area. It is measured by the needle puncture method, that is, samples are selected for puncture statistics, and the ratio of the number of times the needle tip contacts the natural grass to the total number of sample points is used as the coverage index.

[0194] The underground biomass of natural grass was measured by weighing the dry weight of the roots. The stems and leaves above the natural grass matrix were cut off, the roots were rinsed with clean water, and the roots were dried at 80°C for 24 hours, and then the mass was weighed with a balance.

[0195] Data processing

[0196] SPSS19.0 software was used to process and analyze the measurement data, and Excel2020 software was used to make graphs.

[0197] (2) Results Analysis

[0198] Effect of trampling on the color of natural grass in different substrate structures:

[0199] Depend on Figure 5 It can be seen that with the increase of trampling treatment time, the color of natural grass gradually changed from dark green to more green, a few dead leaves, and even most grass dead leaves: Treatments 1 and 2 have a stem base protection layer structure in the substrate, which can provide good stem base protection against trampling stress. After the trampling treatment, the stem and leaf color was light green to dark green, with sporadic dead leaves. Treatments 3 and 4 had no stem base protection layer structure, so the stem and leaf color was more green leaves and a few dead leaves. Treatment 5 had no stem base protection layer structure, and after the trampling treatment, the stem and leaf color was mostly dead leaves and a few green leaves. With the increase of recovery treatment time, the color of natural grass gradually recovered to light green or even dark green: treatments 1 and 2 recovered faster, and finally recovered to dark green to light green; treatment 5 was a sand base with poor water and fertilizer retention, and there was no stem base protection structure, so the color of natural grass recovered slowly, and finally recovered to mostly light green with a few dead leaves.

[0200] Effects of trampling on the stem and leaf height of natural grasses with different substrate structures:

[0201] Depend on Figure 6It can be seen that with the extension of the trampling treatment time, the height of the natural grass stems and leaves of each matrix combination continued to decrease. Among them, the stem base protection layer in the matrix structure of treatment 1 was thicker and more elastic, which slowed down the damage to the stem base of natural grass caused by trampling, and the height of the natural grass stems and leaves decreased the least. However, due to the lack of stem base protection layer structure and the small matrix thickness in treatments 4 and 5, the natural grass stems and leaves fell seriously due to trampling treatment, and the height decreased sharply. With the increase of the recovery treatment time, the height of the natural grass stems and leaves of each matrix combination continued to recover. Among them, the stem and leaf height of treatments 1 and 2 recovered the fastest, and the mean stem and leaf height increased to 7.03cm and 6.53cm respectively at the end of the recovery treatment. The stem and leaf height of treatments 3 and 4 recovered faster, and the stem and leaf height of treatment 5 recovered the slowest, and the mean stem and leaf height was only 4.03cm at the end of the recovery treatment.

[0202] Depend on Figure 7 It can be seen that the height of natural grass in each matrix structure without trampling treatment increases rapidly with time: treatments 1 and 3 grow the fastest, treatments 2 and 4 grow relatively fast, and treatment 5 grows the slowest. The difference in natural grass height between treatments continues to increase.

[0203] Effect of trampling on natural grass coverage with different substrate structures:

[0204] The test results show that under the same trampling intensity, the natural grass coverage of each matrix structure decreases with time. Figure 8 It can be seen that there are significant differences in cover between treatments with different matrix structures: after trampling, the cover of treatments 1 and 3 was the largest, the cover of treatments 2 and 4 was relatively large, and the cover of treatment 5 was the smallest. Treatments 2 and 4 had the same matrix material and thickness, but only the matrix structure was different. The cover of treatment 2 after trampling was greater than that of treatment 3, indicating that the stem base protection structure of treatment 2 had a certain mitigating effect on trampling damage.

[0205] After the restoration treatment, the natural grass coverage of each substrate gradually recovered to a certain extent. After the restoration treatment, the natural grass coverage of each substrate structure was treatment 1> treatment 2> treatment 3> treatment 4> treatment 5. The coverage of treatment 2 recovered to a greater extent, exceeding that of treatment 4 with the same substrate material thickness, indicating that the stem base protection layer structure played a certain role in the recovery of natural grass coverage after trampling; the substrate structure of treatment 2 with a stem base protection layer was more reasonable, and even if the substrate thickness was smaller, the growth recovery ability of natural grass was stronger than that of treatment 3; the height recovery of treatment 5 was the smallest, and it only recovered to 61%.

[0206] Effects of trampling on underground biomass and fibrous root number of natural grasslands with different substrate structures:

[0207] The test results showed that treatments 1-4 significantly increased the underground biomass and the number of fibrous roots of natural grass compared with treatment 5. After trampling, the underground biomass and the number of fibrous roots of treatment 1 were 155.8% and 229.5% of those of treatment 5, respectively. After recovery, the underground biomass and the number of fibrous roots of each matrix structure increased to varying degrees: the underground biomass of treatments 1 and 2 increased the most, by 15.8% and 11.0% respectively compared with the trampling stress, and the underground biomass of treatment 5 increased the least; the number of fibrous roots of treatments 1, 2, 3, and 4 increased more, by 26.4%, 19.2%, 20.9%, and 14.2% respectively compared with the trampling stress, while the number of fibrous roots of treatment 5 did not increase significantly.

[0208]

[0209] Note: Different letters in the table indicate that the indicators are significantly different among different treatments (P<0.05).

[0210] Test conclusion:

[0211] During the trampling treatment, the color, stem and leaf height, and coverage of natural grass planted in different substrates continued to decrease. Compared with the sand-based substrate, the natural grass of other substrate structures performed better. After the trampling treatment, the color, stem and leaf height, and coverage of natural grass in treatment 1 were the highest, treatments 2 and 3 were higher, treatment 4 was lower, and treatment 5 was the lowest. After the recovery treatment, the color, height, and coverage of natural grass in each treatment recovered to varying degrees, and the recovery ability of natural grass in treatment 2 was better than that in treatments 3 and 4; the underground biomass and fibrous root number indicators of each treatment increased to a certain extent, among which treatment 1 had the largest increase. The color, height, and coverage of natural grass in each treatment were ranked as treatment 1>treatment 2>treatment 3>treatment 4>treatment 5.

[0212] Trampling treatment will reduce the color, height, and coverage of natural grass, but the decline of the above indicators in treatments 1 and 2 is relatively low. After the trampling treatment, the color, height, and coverage indicators are still at a high level, indicating that the matrix structure of treatments 1 and 2 is relatively reasonable, with strong trampling resistance, suitable for pets to play and lie for a long time. The thickness of the matrix of treatment 1 is 40mm, which is 33% thicker than that of treatment 2. Although the color, height, and coverage indicators perform best, the cost of the matrix increases by about 30%. Considering the visual quality, trampling recovery ability, and production cost factors of natural grass, treatment 2 is more suitable for mass production of natural grass pet blankets.
