Description
Technical Field
The invention belongs to the technical field of plant-growing nets, and particularly relates to an agricultural residue fiber plant-growing net and a preparation method and application thereof.
Background
When the landslide and the soil slope are treated in a greening way, in order to prevent the soil from being eroded and loosened by rainwater to cause landslide or soil and stone flow, engineering personnel often lay a plant-growing net on the slope surface when carrying out water and soil conservation engineering, so as to increase the soil stability of the surface of the slope, grass seeds can be sprayed on the plant-growing net and the soil surface, the roots of the grass seeds can pass through the plant-growing net and are grabbed in the soil, and therefore the stability of the soil can be further improved.
However, a certain time is required for the growth of grass seeds, and in the time, the vegetation net is easy to deform and displace under the scouring of wind and rain, and cannot effectively catch the ground soil and small sand, so that the effect of water and soil conservation is poor.
How to avoid the deformation and displacement of the plant growing net and how to promote the growth of grass seeds so as to promote the combination of the grass seeds and the plant growing net is a problem which needs to be studied at present.
Disclosure of Invention
The invention provides an agricultural residue fiber plant net and a preparation method and application thereof, and aims to solve the technical problems that the existing plant net is easy to deform, translocation and poor in water and soil conservation effect in the background art.
The aim of the invention can be achieved by the following technical scheme:
an agricultural residue fiber plant net comprises a first fiber fabric and a second fiber fabric which are sequentially stacked from bottom to top; the first fibrous web is a surface hydrophilically modified fibrous web and the second fibrous web is a surface hydrophobically modified fibrous web.
The preparation method of the agricultural residue fiber plant net comprises the following steps:
firstly, coarsening the surface of bast fibers, weaving to form a fiber net, immersing the fiber net in a hydrophilic modification solution for 0.5-1h, taking out the fiber net, and naturally airing the fiber net to obtain a first fiber fabric;
secondly, weaving bast fibers to form a fiber net, immersing the fiber net in the hydrophobic modification solution for 0.5-1h, taking out the fiber net, and naturally airing the fiber net to obtain a second fiber fabric;
and thirdly, combining the first fiber fabric and the second fiber fabric to form a grid structure, so as to obtain the agricultural residue fiber plant-growing net.
The fiber plant net is prepared from agricultural residues (bast fibers) as raw materials, so that the utilization rate of agricultural residue resources is improved, the application of the existing chemical polymer materials in the slope protection treatment is reduced, and secondary pollution harm is reduced. The first fiber fabric of the fiber plant net is a hydrophilic layer, and the hydrophilic surface is beneficial to collecting moisture; the second fiber fabric of the fiber plant net is a hydrophobic layer, the hydrophobic surface is favorable for water drops to slide to a hydrophilic layer, the hydrophilic surface is favorable for water absorption, and the hydrophobic surface is favorable for water drainage.
Wherein, the dosage ratio of the fiber web to the hydrophilic modification solution to the hydrophobic modification solution is 1g:10-15mL:10-15mL.
As a further aspect of the present invention, the bast fiber includes at least one of ramie fiber, flax fiber, jute fiber, abaca fiber, sisal fiber, and kenaf fiber.
Bast fibers are long spindle-shaped dead cells with pointed ends, the cell wall thickness and the cell cavity are long and narrow gaps, and the bast fibers contain cellulose, so that the bast fibers are tough and elastic and can resist breakage and bending.
As a further aspect of the present invention, the surface roughening treatment may be any treatment that breaks up fibers or can spread out fibers and increase surface roughness.
As a further aspect of the present invention, the above-mentioned hydrophilic modification solution comprises the following raw materials: hydrophilic diamino silicone oil, vinyl triethoxysilane, glycol, carboxymethyl starch and water; specifically, the weight parts are as follows: 10-20 parts of hydrophilic diamino silicone oil, 0.5-0.8 part of vinyl triethoxysilane, 1-2 parts of ethylene glycol, 0.2-0.7 part of carboxymethyl starch and 70-90 parts of water.
In general, after the hydrophilic treatment is performed on the fiber, although the water storage capacity of the fiber is improved, a liquid film is formed on the surface of the hydrophilically modified fiber, so that absorbed moisture cannot be effectively collected, and therefore, the improvement of the water storage capacity of the fiber by the hydrophilic treatment is very limited in practice. Therefore, the fibers are firstly scattered, the fiber wool of the fibers is opened, so that the surface area of the fibers is increased, the spread fiber wool damages the formation of a liquid film, and meanwhile, water vapor is easy to condense on the fiber wool and then slide off, so that the water storage capacity of the first fiber fabric of the vegetation net is greatly improved, and after the water storage capacity of the first fiber fabric is increased, the stability of the vegetation net is increased, so that the vegetation net is not easy to displace; secondly, wetting soil and reducing broken mud; thirdly, sufficient moisture is provided for grass seeds to promote the growth of the grass seeds.
As a further aspect of the present invention, the above-mentioned hydrophobically modified solution is an alcoholic solution of polydimethylsiloxane; specifically, the weight parts are as follows: 15-30 parts of polydimethylsiloxane and 70-85 parts of absolute ethyl alcohol.
As a further scheme of the invention, the fiber plant net is of a grid structure, and the mesh size of the grid structure is 6-12mm.
As a further scheme of the invention, the thickness of the fiber plant net is 0.5-1.2cm, and the mass ratio of the first fiber fabric to the second fiber fabric is 3:2.
as a further aspect of the present invention, the first fiber web and the second fiber web are bonded by stitching or bonding.
The agricultural residue fiber plant net is applied to soil protection.
The invention has the beneficial effects that:
1. the fiber planting net is of a two-layer structure and comprises a first fiber fabric and a second fiber fabric which are sequentially stacked from bottom to top, wherein the second fiber fabric is a hydrophobic layer, and the first fiber fabric is a hydrophilic layer, so that the first fiber fabric is easier to store moisture, and on one hand, the weight of the fiber planting net is increased so as to be more stably fixed on a slope; on the other hand, the land is moistened, the broken slag and the broken soil are prevented from rolling down from the holes of the grid, and meanwhile, the stored water also provides necessary survival conditions for the grass seeds in the plant growing net; in addition, the second fiber fabric is a hydrophobic layer, so that the water storage capacity of the second fiber fabric can be weakened, and water flows unidirectionally to the first fiber fabric.
2. The first fiber fabric of the fiber plant net is subjected to surface roughening treatment, so that the surface roughness of the fibers of the first fiber fabric is high, on one hand, the spread fiber wool can prevent fine broken soil from rolling off, and on the other hand, the high surface roughness can prevent the surfaces of the fibers from forming a liquid film, so that the fibers of the first fiber fabric can absorb water more effectively.
