Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.

Example 1:

a degradable ecological vegetation blanket, refer to fig. 1 and fig. 2 and fig. 3, it is polyethylene net 4, thin cotton 3, seed, fertilizer and soil improvement agent 2 attached to thin cotton 3 and the rigid plastic stake 6 used for fixing that from top to bottom arrange in proper order, wherein polyethylene net 4 links to each other with thin cotton 3 through the adhesive of water-solubility, this vegetation blanket lays on present situation soil construction domatic 1 to fix with rigid plastic stake 6, has laid sandy soil on the top layer of polyethylene net 4, thin cotton 3 is the natural degradable material. Thin cotton 3 also can choose degradable ecological cloth for use simultaneously, in order to realize the degradable effect, degradable fibre is chooseed for use to the material of ecological cloth. The seeds, the fertilizer and the soil conditioner 2 are directly adhered to the ecological cloth, so that the rapid growth of the plants is realized, the ecological cloth can be adsorbed on the slope when meeting water, the contradiction between scouring and germination can be solved, and the stable growth of the plants is determined. The plant growth blanket can maintain the long-term and stable greening of the slope surface, and can maintain the long-term and stable growth of the slope surface greening through the mutual cooperation of the fertilizer and the soil conditioner.

Specifically, the tissue 3 is made of degradable composite fibers; the corrosion resistant effect at the initial construction stage can be exerted by using the natural material with high flexibility, air permeability and water locking property, so that the environmental protection effect is improved; in order to enable the plants to uniformly germinate and grow stably and vigorously, the seeds, the fertilizer and the soil conditioner 2 are adhered to the lower surface of the cotton floss 3 through a water-soluble adhesive, and the water-soluble adhesive is a water-based polymer-cyanate-labile adhesive; the length of the cotton floss 3 is 2m multiplied by 25m, and the mesh size of the polyethylene net 4 is 15mm multiplied by 20 mm; the polyethylene net 4 is a surface net for protecting the thin cotton 3 from being damaged; in order to firmly fix the vegetation blanket, the distance between the hard plastic piles 6 on the slope surface is 1m, and the side surface of the outer wall of each hard plastic pile 6 is provided with a plurality of barbs to prevent the hard plastic piles from being pulled out. As shown in fig. 4; the length of the hard plastic pile 6 is 230 mm.

The working principle is as follows: fine-grained soil is easily lost due to rainfall or erosion, and in order to promote plant growth, protection against soil loss cannot be lacking. After construction, the degradable ecological cloth can be slowly separated from the net along with dew or rainfall at night and is adsorbed into soil before seeds germinate. It can replace root hair, has obvious effect on preventing the loss of fine soil, seeds and fertilizer, and can be said to play the role of the initial root hair. The vegetation blanket is characterized in that a polyethylene net 4 and a thin cotton 3 on the surface are connected with each other by a water-soluble adhesive, the polyethylene net 4 and the thin cotton 3 are separated by dew or moisture condensed at night, the thin cotton 3 absorbing water keeps a concave-convex inclined surface and is tightly attached to a current soil construction slope surface 1, in order to prevent seeds from drying due to wind, the seeds, fertilizers and soil conditioners 2, the seeds, the fertilizers and the soil conditioners 2 are attached to the lower surface of the thin cotton 3 by the water-soluble adhesive containing macromolecules, the seeds are separated from the thin cotton 3 by a little water and fall on a construction base surface, and the fertilizers and the soil conditioners are mutually matched to promote the seeds to germinate rapidly.

Example 2:

another object of the present invention is to provide a method for preparing the above degradable ecological plant growing blanket, which is applied to the preparation method of example 1, and the preparation method specifically includes the following steps: s1, removing weeds, gravels, floating soil and sundries on the construction slope surface 1 of the current soil;

s2, burying the thin cotton 3 and the polyethylene net 4 into the top of the slope for 10cm, and enabling the rest part to be tightly attached to the slope surface and unfolded;

and S4, driving the hard plastic pile 6 for fixing, and paving sandy soil on the surface layer of the polyethylene net 4.

Wherein, in order to promote the growth of the roots and leaves of the grass, the soil covering 5 is soil which is favorable for drainage, therefore, the soil covering 5 is sandy soil, and the thickness of the laid sandy soil is about 2 cm. When the pile driving and fixing are carried out, as shown in fig. 3, the transverse spacing and the longitudinal spacing of the hard plastic piles 6 on the slope surface are ensured to be 1m, the hard plastic piles 6 are driven into the middle part of the thin cotton 3 for fixing, and the average distance is every 100m²The number of the hard plastic piles 6 of the vegetation blanket is 116.1; 3 months after completion, except for rainy days, the watering is best every day; in daily maintenance, water should be sprayed frequently to promote absorption at roots, and relatively, one-time large-amount water spraying is more effective than small-amount multiple-time water spraying. The phenomenon of the grass blades bending represents that water is lacking. The water is sprayed once every 3-5 days in summer, and the water is properly sprayed when the grass leaves are bent in spring and autumn. Should avoid the sun from sprinkling when the sun is empty, the time is preferably morning or eveningAnd (4) evening.

It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and the present invention is not limited thereto, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications can be made to the technical solutions described in the foregoing embodiments or equivalent substitutions for some technical features, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
