Description

Agricultural residue fiber plant-growing net and preparation method and application thereof
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 greening and treating hillside and soil slope, in order to prevent soil from erosion and loosening by rainwater and causing landslide or soil-rock flow, engineering personnel often lay a planting net on the slope surface when performing water and soil conservation engineering so as to increase the soil stability of the surface of the hillside land, and can spray grass seeds on the planting net and the soil surface, and the roots of the grass seeds can penetrate through the planting net and be caught in the soil, so that the stability of the soil can be further improved.
However, the grass seeds need a certain period of time for growing, and in this period of time, the planting net is easy to deform and displace under the washing of wind and rain, and cannot effectively catch soil on the ground surface and small sand stones, so that the water and soil conservation effect is poor.
How to avoid the deformation and displacement of the planting net and how to promote the growth of grass seeds so as to promote the combination of the grass seeds and the planting net is a problem which needs to be researched urgently at present.
Disclosure of Invention
The invention provides an agricultural residue fiber plant net and a preparation method and application thereof, aiming at solving the technical problems that the existing plant net is easy to deform and translocate and has poor water and soil conservation effect in the background art.
The purpose of the invention can be realized by the following technical scheme:
an agricultural residue fiber plant-growing net comprises a first fiber fabric and a second fiber fabric which are sequentially stacked from bottom to top; the first fiber fabric is a fiber net with the surface modified by hydrophilicity, and the second fiber fabric is a fiber net with the surface modified by hydrophobicity.
The preparation method of the agricultural residue fiber vegetation net comprises the following steps:
firstly, roughening the surface of bast fiber, weaving to form a fiber net, soaking in a hydrophilic modification solution for 0.5-1h, taking out, and naturally airing to obtain a first fiber fabric;
step two, weaving bast fibers to form a fiber net, soaking the fiber net in a 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 to obtain the agricultural residue fiber vegetation net.
The fiber plant growing net is prepared by taking 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 material in slope protection and treatment is reduced, and secondary pollution hazards are reduced. The first fiber fabric of the fiber plant net is a hydrophilic layer, and the hydrophilic surface is favorable for collecting moisture; the second fiber fabric of the fiber plant-growing net is a hydrophobic layer, the hydrophobic surface is favorable for water drops to slide to the 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 net to the hydrophilic modification solution and 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.
The bast fiber is a long spindle-shaped dead cell with two tapered ends, has thick cell wall, narrow cell cavity and cellulose content, and is tough and elastic and can resist breaking and bending.
In a further aspect of the present invention, the surface roughening treatment may be fiber scattering or any treatment capable of spreading fibers and increasing the surface roughness.
As a further aspect of the present invention, the hydrophilic modification solution comprises the following raw materials: hydrophilic diamino silicone oil, vinyl triethoxysilane, glycol, carboxymethyl starch and water; specifically, the weight portions 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 hydrophilic modified fiber, so that the absorbed water cannot be effectively collected, and thus 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 hairs of the fibers are opened, the surface area of the fibers is increased, the expanded fiber hairs destroy the formation of a liquid film, and meanwhile, water vapor is easy to condense on the fiber hairs and then slides off, so that the water storage capacity of the first fiber fabric of the plant-growing net is greatly improved, and after the water storage capacity of the first fiber fabric is increased, the stability of the plant-growing net is improved, and the plant-growing net is not easy to displace; secondly, soil is moistened, and broken mud is reduced; thirdly, the grass seeds are provided with sufficient water to promote the growth of the grass seeds.
In a further embodiment of the present invention, the hydrophobically modified solution is an alcoholic solution of polydimethylsiloxane; specifically, the weight portions 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-growing net is of a grid structure, and the mesh size of the grid structure is 6-12mm.
As a further aspect of the present invention, the thickness of the fibrous web is 0.5 to 1.2cm, and the mass ratio of the first fiber fabric to the second fiber fabric is 3:2.
as a further scheme of the invention, the combination mode of the first fiber fabric and the second fiber fabric is pressing or bonding.
The agricultural residue fiber vegetation net is applied to soil protection.
The invention has the beneficial effects that:
1. the fiber planting net has 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, and the fiber planting net is more stably fixed on a slope; on the other hand, the land is moistened, the broken slag and the broken soil are prevented from falling from the pores of the grids, and meanwhile, the stored water also provides necessary survival conditions for the grass seeds in the vegetation 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 to the first fiber fabric in a one-way mode.
2. The first fiber fabric of the fiber plant net is subjected to surface roughening treatment, the surface roughness of the first fiber fabric fiber is larger, on one hand, the unfolded fiber hairs can prevent fine broken soil from rolling off, on the other hand, the larger surface roughness can prevent the liquid film from being formed on the fiber surface, and therefore the first fiber fabric fiber can absorb moisture more effectively.
