Non-woven fabrics for greening
It has the following functions: reducing rainwater erosion of the soil, preventing seeds from being lost with rainwater, reducing soil evaporation, maintaining soil moisture and preventing birds and rodents from foraging for seeds.
Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials that are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating. Rich colors, low price, recyclable and other characteristics. Polypropylene pellets are mostly used as raw materials, and are produced by a continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because it has the appearance and certain properties of cloth. Non-woven products are mainly used in infrastructure construction fields such as roads, railways, water conservancy, electricity, soil and water conservation, and environmental protection and greening.
Application of non-woven fabrics in slope greening Non-woven fabrics are an indispensable auxiliary material in slope greening and an important factor in soil and water conservation and plant community growth. Slope cover non-woven fabric can resist rain erosion, moisturize, retain heat, moisturize, retain water, reduce direct UV radiation, etc. It plays an important role in seed germination rate and germination speed. If the selection ratio is unreasonable, it will The desired effect cannot be achieved. Soil and water conservation is the basis for vegetation restoration. Generally refers to the stability of the covering layer, which does not fall off or drain, and has a certain ability to resist erosion. Therefore, it is necessary to select the thickness of the non-woven fabric from thick to thin to form a protective structure. However, the selection must be based on the comprehensive situation of the site conditions, and fully consider the slope of the site, the structure type and thickness of the guest soil material. If the non-woven fabric is too thick, the matrix layer will become compacted, affecting plant growth. If the non-woven fabric is too thin, it will not be able to maintain water and soil. Effect. Vegetation communities are the core of soil and water conservation. The long-term stability of slope soil and water is formed by the staggered extension of plant roots. Slopes often have tight water resources and expensive irrigation systems. Non-woven fabrics have become a necessary material to maintain water and fertilizer, and play a decisive role in construction and later maintenance. The matching ratio with adhesives and water-retaining agents depends on the slope environment and the application conditions of other materials.
Water-retaining agent
It is a non-toxic, non-corrosive functional polymer that can absorb natural water twice its own weight. It is like a miniature reservoir for slow absorption by seeds and plant roots. Repeatedly releases and absorbs moisture. Save irrigation and maintenance costs.
. Adhesive
It is a linear polymer with strong biological stability, non-toxic and corrosive. It can form a granular structure in the soil and fix topsoil and other media. It can be combined with seeds. , fertilizer, wood fiber mulch, etc. are used in combination.
Hand-operated seeder
Easy to operate and highly efficient, it can sow 10,000 square meters a day, evenly, and can also be used to apply granular fertilizers.
, Three-dimensional ecological network
Guest soil spraying base material. Three-dimensional mesh slope protection technology combines the advantages of geonet and vegetation slope protection, and can effectively solve the protection problems of rocky slopes and high and steep slopes. The three-dimensional mesh slope greening and slope protection technology not only significantly improves the overall and local stability of the slope, but also facilitates the growth of slope vegetation. At the same time, the project cost is also low, which is in line with the development direction of slope engineering. It has great application value in soil and water conservation in my country. Through the growth activities of plants, the purpose of root system reinforcement and stem and leaf erosion prevention is achieved. After ecological slope protection technology, dense vegetation coverage can be formed on the slope surface, and an intertwined root system can be formed on the topsoil layer, effectively inhibiting the impact of heavy rain runoff on the slope. Erosion, increasing the shear strength of the soil, reducing pore water pressure and soil self-gravity, thereby greatly improving the stability and erosion resistance of the slope.
Three-dimensional network slope technology combines the advantages of geonet and plant slope protection, and plays the role of composite slope protection. When the vegetation coverage rate of the slope reaches above, it can withstand the erosion of light rain; when the coverage rate reaches above, it can withstand the erosion of heavy rain. When the plants grow luxuriantly, the runoff flow rate that can resist erosion reaches /, which is more than twice that of ordinary turf. The existence of the three-dimensional network has a good effect on reducing the evaporation of water in the slope soil and increasing the infiltration amount. At the same time, because the geonet material is black polyethylene, it has the effect of absorbing heat and retaining heat, which can promote seed germination and is beneficial to plant growth.
, Galvanized chain link wire mesh (slope protection net)
Soil spraying base material. Chain link fence, also known as rhombus mesh and hook wire mesh, is made by crocheting metal wires of various materials using a chain link fence machine. It can be divided into two types: folding and shrinking handles and twisting and locking handles. Material wire, stainless steel wire, high-quality low carbon steel wire, galvanized wire, iron wire, etc. According to the name, it is divided into chain link fence, rhombus net, trapezoidal net, ring net, chain link net, hook net, anchor net, protective net, breeding fence net, and flexible net. According to the surface treatment, we can choose electro-galvanized chain link fence, hot-dip galvanized chain link fence, plastic coated chain link fence (, plastic coated), dipped plastic chain link fence, spray plastic chain link fence. Decorative chain link fence according to purpose, sports ground chain link fence (simple guardrail, protective chain link fence, greening chain link fence. Another classification of stainless steel chain link fence (material,,,,, etc. do not require surface treatment). The material is of high quality and low Carbon steel wire (iron wire), stainless steel wire, aluminum alloy wire. Weaving and characteristics: uniform mesh, flat mesh surface, simple weaving, crocheted, beautiful and elegant mesh with high quality, wide mesh width, thick wire diameter, not easy to corrode , long life and strong practicability.
The principle of using chain link fence for mountain protection is to mainly use the air permeability effect of chain link fence. It is used in large-scale mountain protection to fix rocks and use green grass. Spray to achieve the effect of self-curing later. It is a perfect combination of greening and protection.

7. The following is a brief introduction to the selection of commonly used grass species for soil and water conservation (highway slope protection greening grass species, railway slope protection greening grass species, river reservoir slope protection greening grass species) and vegetation establishment
Generally speaking Generally speaking, the basic principle for selecting grass species and varieties for soil and water conservation is the principle of ecological adaptability, that is, based on the zonal climate, soil and other characteristics of the area, as well as the specific local microclimate, soil type, topography, landform and hydrology of the specific location. Screen out high-quality grass seeds, varieties and mixing ratios suitable for local planting.
The most commonly used grass species for soil and water conservation mainly include perennial ryegrass, tall fescue, bermudagrass and other grass species; white clover, alfalfa, acacia, magnolia and other leguminous grass species, and shrubs . Grass seeds used for soil and water conservation must be mixed sowing, which can not only increase the diversity of species and make up for the shortcomings of a single grass species, but also maintain the stability of the vegetation community for a long time. For example, in a mixed grass species composed of perennial ryegrass, tall fescue, bermudagrass and white clover, ryegrass can cover the ground in a short period of time, thereby effectively suppressing the growth of weeds and preventing soil erosion, setting the stage for the success of other grass species. Provide good environmental conditions for establishment. After a year or two, the ryegrass fades away, while tall fescue, bermudagrass and white clover continue to grow under the ryegrass's protection. At the same time, because the leguminous plants are taller, their photosynthesis is not affected by the grasses and they can coexist together. Moreover, white clover has a nitrogen-fixing function and can provide a certain amount of nitrogen fertilizer for tall fescue and bermudagrass, thus making the entire community Achieve a virtuous cycle. Since most of the areas where soil and water conservation projects are required are sloping land or sloping farmland with poor soil conditions, spray seeding and covering with non-woven fabrics are often used during planting. The basic principle is to mix the germinated seeds into a container containing a certain proportion of water, fiber covering, adhesive, fertilizer, water retaining agent, soil loosening agent and other materials, and use a centrifugal pump to spray the mixed slurry through a hose. onto the soil to be sown. Its main advantage is that it can ensure the contact between the seeds and the soil after sowing, so that the seedlings can quickly emerge into a flat surface, which is much earlier than conventional sowing. The semi-permeable moisturizing layer of fiber and colloid can greatly reduce water evaporation and provide good moisture, nutrients and shade conditions for seed germination. Due to the existence of the adhesive, the seeds on the slope will not be washed away when encountering wind, rain or flooding, and it has a good effect of consolidating the soil and protecting the seedlings. Using this method, sowing is even, seeds are saved, and the efficiency is very high.
When sowing by hand, special attention should be paid to the uniformity of sowing and the uniformity of moisture. You can use the sand mixing method to increase the uniformity and divide the seeds into two equal parts and cross-sow in different directions to increase the sowing. The control of moisturizing in the form of uniformity is mainly to grasp the bottom moisture and to replenish water in time by taking advantage of the rainy season climate and high temperature.
From the perspective of project cost, the most basic type of grass species used for soil and water conservation in the south of central China is the sowing of a single bermudagrass, which has the lowest cost. The second option is to use bermudagrass + perennial ryegrass or bermudagrass + tall sheep. Grass, the cost is slightly higher, that is, bermudagrass + perennial ryegrass + white clover or bermudagrass + tall fescue + white clover. If you encounter a soil and water conservation project with a large slope, it is best to add a small amount of dark clover to the above formula. Rooted alfalfa species and ornamental shrubs such as Amorpha amorpha, Magnolia multiflora, etc.
8. The relationship between grass seed quality and grass seed price and the essentials for grass seed selection
>Grass seed is the most important and basic production material for the construction of greening projects. Grass seed quality is the key factor that determines the success or failure of the project. one.
>So, is the grass seed you choose more expensive or better? This has to be said about the relationship between grass seed quality and price
>First of all, according to the national standards of relevant grass seed classification (using forage seed testing procedures/degree analysis,/other plant seed number determination,/bud test,/ Grass seeds can be divided into quality grades such as first, second and third grade based on purity, germination rate, number of other plant seeds and moisture. All the following are classified as unqualified grass seeds.
>The following are examples of several commonly used grass seeds, and the main indicator of germination rate of grass seeds is used as an example to illustrate the classification method of different quality levels of grass seeds
/> >Take our commonly used Sophora acacia seeds as an example. The germination rate of first-level seeds is above, the germination rate of second-level seeds is above, the germination rate of third-level seeds is above, and the germination rate below is unqualified grass seeds.
> Take For example, the germination rate of our commonly used bermudagrass species is above the first-level seed, the second-level seed germination rate is above, the third-level seed germination rate is above, and the following are unqualified grass species.
> Take our commonly used purple flowers For alfalfa seeds, for example, the first-level seed germination rate is above, the second-level seed germination rate is above, the third-level seed germination rate is above, and the following are unqualified grass species.
>Take our commonly used white clover species as an example. The germination rate of first-level seeds is above, the germination rate of second-level seeds is above, the germination rate of third-level seeds is above, and the germination rate below is unqualified grass seeds.
>As can be seen from the above, the difference in germination rates of grass seeds of different quality levels is Large.
>Our common ryegrass species, tall fescue grass species, bentgrass species, bluegrass species, basil grass species, red clover species, horseshoe grass species, zoysia grass species, Magnolia shrub seeds, Lespedeza shrub seeds, pigeon pea shrub seeds, pig bean shrub seeds, acacia shrub seeds, etc. will not be listed one by one.
>Secondly, there are clarity, number of other plant seeds, and moisture. Content and other indicators also directly affect the quality grade of grass seeds.
>In summary, it can be seen that common misunderstandings in grass seed selection have the lowest price.
>Correct grass seed selection essentials: grass seed quality and grass seed price The most cost-effective among them, that is, the highest return on your investment.
>Finally, we hope that every grass seed we provide you will return a piece of green for your investment, and your project will be green. Success is also our constant pursuit.
