Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation technology, and more specifically, to a planting protective cloth. Background Technology

[0002] Traditional protective fabrics have many shortcomings in the process of planting vegetation on slopes. These fabrics are mostly made of non-woven material. For example, the slope repair method disclosed in Chinese Patent 202110237378.3 involves spraying mud and sowing seeds on the slope, then covering it with non-woven fabric for protection. The initial intention of this method was to protect newly sown plant seeds from external environmental interference and promote seed germination and growth. However, in practice, the non-woven protective fabric exerts significant restraining force on the plant seeds.

[0003] Due to its material properties, non-woven fabric is often dense and has poor air permeability. When used to cover newly sown slopes, it can compress the plant seeds underneath. This compression not only restricts the seeds' growth space but also affects gas exchange and water absorption between the seeds and the soil, resulting in low germination rates. Because many seeds fail to germinate successfully, the vegetation coverage on the slope is far lower than expected. This not only affects the greening effect of the slope but may also exacerbate environmental problems such as soil erosion and water loss. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a planting protective cloth.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A planting protective cloth includes an upper protective cloth, on which a plurality of constraint-reducing zones are provided to accommodate the germination and penetration of seeds, with intermediate intervals between adjacent constraint-reducing zones.

[0007] In some embodiments, the thickness of the upper protective fabric in the constraint-reduced area is less than that in other areas, and this thickness allows the seed to break through the constraint-reduced area after germination.

[0008] Furthermore, the upper protective fabric is made of polypropylene nonwoven fabric, polyethylene woven fabric, or polypropylene woven fabric.

[0009] Furthermore, the linear array within the constraint reduction region has several circular holes.

[0010] Furthermore, the plurality of said circular holes form a planting array.

[0011] Furthermore, the linear array within the constraint reduction region has several long slits.

[0012] Furthermore, the multiple elongated slits form a planting array.

[0013] Furthermore, a lower protective fabric is provided at the bottom of the upper protective fabric. The upper and lower protective fabrics are joined together by hot-melt stitching at the middle interval, and a rectangular placement cavity is formed between the planting array and the lower protective fabric.

[0014] Furthermore, a water-retaining layer is added to the lower surface of the upper protective fabric or between the upper and lower protective fabrics.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting up several constraint-reducing zones to accommodate seed germination and penetration, this utility model effectively reduces the constraint force on plant seeds, improves the seed germination rate, thereby increasing the green coverage rate of the slope, helping to prevent environmental problems such as soil erosion and water loss, and has a better water and soil conservation effect.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0021] Example 1

[0022] like Figure 1 As shown, a planting protective cloth is mainly made of polypropylene nonwoven fabric, polyethylene woven fabric or polypropylene machine-woven fabric. The planting protective cloth includes a single-layer upper protective cloth 100. The upper protective cloth is provided with a number of constraint weakening zones to accommodate the germination and penetration of seeds, and an intermediate interval 102 is left between adjacent constraint weakening zones.

[0023] Furthermore, the linear array within the constraint reduction region has several circular holes 101.

[0024] Furthermore, the multiple circular holes form a planting array, with intermediate intervals between adjacent planting arrays.

[0025] The specific steps for making this planting protective fabric are as follows:

[0026] 1) Use polypropylene nonwoven fabric with a basis weight of 100 g / m² as the base material; alternatively, polypropylene woven fabric with a basis weight of 200 g / m² or polyethylene woven fabric with a basis weight of 150 g / m² can be selected.

[0027] 2) Use a laser drilling device to drill holes in an array on the upper protective fabric. The hole diameter is 1 cm and the hole spacing is 1 cm.

[0028] When using this planting protective fabric, it is laid on the slope surface that needs to be greened, and the seeds can germinate from the round holes in the upper protective fabric. This planting protective fabric can reduce the restraint on plant seeds, improve the germination rate, and at the same time, it has the functions of heat preservation and resistance to rain erosion, providing a good growth environment for seeds.

[0029] Example 2

[0030] like Figure 2 As shown, a planting protective cloth is mainly made of polypropylene nonwoven fabric, polyethylene woven fabric or polypropylene machine-woven fabric. The planting protective cloth includes a single-layer upper protective cloth 100. The upper protective cloth is provided with a number of constraint weakening zones to accommodate the germination and penetration of seeds, and an intermediate interval 102 is left between adjacent constraint weakening zones.

[0031] Furthermore, the linear array within the constraint reduction region has several long slits 103.

[0032] Furthermore, the multiple elongated slits form a planting array, with an intermediate interval 102 between adjacent planting arrays.

[0033] The specific steps for making this planting protective fabric are as follows:

[0034] 1) Use polypropylene nonwoven fabric with a basis weight of 100 g / m² as the base material; alternatively, polypropylene woven fabric with a basis weight of 200 g / m² or polyethylene woven fabric with a basis weight of 150 g / m² can be selected.

[0035] 2) Planting arrays are set on the upper protective fabric by stamping, with a gap width of 5 mm, a length of 8 cm, and a gap spacing of 2 cm.

[0036] When using this planting protective fabric, it is laid on the slope surface that needs to be greened, and the seeds can germinate from the long strips in the upper protective fabric. This planting protective fabric can reduce the restraint on plant seeds, improve the germination rate, and at the same time, it has the functions of heat preservation and resistance to rain erosion, providing a good growth environment for seeds.

[0037] Example 3

[0038] like Figure 3 As shown, a planting protective cloth is mainly made of polypropylene nonwoven fabric, polyethylene woven fabric or polypropylene machine-woven fabric. The planting protective cloth includes an upper protective cloth 100, on which a plurality of linear arrays of long strip slits are provided.

[0039] Furthermore, the multiple elongated slits form a planting array, with an intermediate interval 102 between adjacent planting arrays.

[0040] Furthermore, a lower protective fabric 200 is provided at the bottom of the upper protective fabric. The upper and lower protective fabrics are joined together by hot-melt stitching at the middle interval. A rectangular placement cavity is formed between the planting array and the lower protective fabric. The size of the rectangular placement cavity can be 10 cm × 10 cm.

[0041] People can directly pull open the long slit to place the seed packet into the rectangular placement cavity between the upper and lower protective fabrics. The seed packet is wrapped in glutinous rice paper and contains grass seeds and nutrient soil.

[0042] When using this planting protective cloth, lay it on the slope surface that needs to be greened. The rice paper will degrade after getting damp, and the seeds will germinate and grow in the rectangular placement cavity. The plants can grow out from the long strips.

[0043] Furthermore, a water-retaining layer is added to the lower surface of the upper protective fabric or between the upper and lower protective fabrics. This water-retaining layer contains water-retaining materials or nutrient solutions, such as superabsorbent polymers, sodium alginate, and humic acid, which can absorb and store large amounts of water and nutrients, providing a continuous supply of water and nutrients for plant seeds. The addition of the water-retaining layer significantly improves the water and fertilizer retention capacity of the planting and maintenance net, providing a continuous supply of water and nutrients for plant seeds and promoting plant growth and development.
