s1: at the beginning of the construction of the mountain wind power plant, collecting moss in the wind power plant field, cutting stems, making the moss dormant and then storing the moss;
s2: drying and storing original soil topsoil soil containing bryophytes;
s3: when the mountain wind power plant construction project is finished and enters an ecological re-greening stage, mixing the pre-stored dormant moss with dry original soil topsoil soil, then uniformly mixing with a water-retaining agent and a binder, putting into a foreign soil spray-seeding machine, adding water and stirring into slurry for later use;
s4: before the fixing net is hooked, non-woven fabric ribs filled with a culture medium are firstly placed on the slope surface, and after the fixing net is hung, the prepared slurry is used for carrying out soil dressing spray seeding;
s5: after the spray seeding is finished, covering a layer of non-woven fabric on the surface of the soil layer to preserve moisture and prevent dust.
Further, in step S1, the specific process of making the moss sleep is: collecting moss growing well on site, breaking stem, drying at 35-40 deg.C for 5-6 hr in drying oven, and allowing the moss to enter dormancy state after dehydration.
Further, in step S2, the specific process of drying the original topsoil layer soil is as follows: the surface soil with moss growing on the site is collected and independently stacked in an open place, dried in the sun or air-dried, and then covered with a film to prevent rainwater from wetting.
Further, in step S4, the cultivation substrate in the non-woven fabric ribs comprises the following components in parts by weight: 60-70 parts of mushroom residues, 10-15 parts of garden soil, 10-12 parts of perlite, 4-6 parts of calcium magnesium phosphate fertilizer, 1-3 parts of slow-release compound fertilizer and 1-1.5 parts of super absorbent resin.

According to the ecological restoration structure and method for slope fast greening of the mountain wind power plant, the dormant moss is adopted to perform greening after reviving, and compared with seed growth greening, the survival rate is higher, the growth state is better, and therefore the ecological greening effect is greatly improved.
Drawings
The invention is further described below with reference to the figures and examples.
Fig. 1 is a schematic structural view of a preferred embodiment of the present invention.
Detailed Description
The present invention will be described in detail below with reference to the drawings and examples.
As shown in fig. 1, the present embodiment provides an ecological restoration structure for fast greening a slope of a mountain wind farm, comprising non-woven fabric ribs 1 filled with a culture medium, a fixing net 2, a substrate soil layer 3 and a greening layer 4 formed by reviving and growing a moss from dormancy, wherein the surface of the greening layer is covered with a non-woven fabric for moisture preservation and dust prevention; the non-woven fabric ribs are all laid on the side slope.
The embodiment also provides a method for fast re-greening slope of mountain wind power plant, which comprises the following steps:
s1: at the beginning of the construction of the mountain wind power plant, collecting moss in the wind power plant field, cutting stems, making the moss dormant and then storing the moss;
s2: drying and storing original soil topsoil soil containing bryophytes;
s3: when the mountain wind power plant construction project is finished and enters an ecological re-greening stage, mixing the pre-stored dormant moss with dry original soil topsoil soil, then uniformly mixing with a water-retaining agent and a binder, putting into a foreign soil spray-seeding machine, adding water and stirring into slurry for later use;
s4: before the fixing net is hooked, non-woven fabric ribs filled with a culture medium are firstly placed on the slope surface, and after the fixing net is hung, the prepared slurry is used for carrying out soil dressing spray seeding;
s5: after the spray seeding is finished, covering a layer of non-woven fabric on the surface of the soil layer to preserve moisture and prevent dust.
In step S1, the specific process of making the moss sleep is: collecting moss growing well on site, breaking stem, drying at 35-40 deg.C for 5-6 hr in drying oven, and allowing the moss to enter dormancy state after dehydration. The dried dormant moss at 35-40 deg.C is easy to recover.
In step S2, the specific process of drying the original topsoil layer soil is as follows: the surface soil with moss growing on the site is collected and independently stacked in an open place, dried in the sun or air-dried, and then covered with a film to prevent rainwater from wetting. The moss in the sun-dried or air-dried soil can easily enter a dormant state due to water loss, so that the moss can be used as 'foreign soil' during foreign soil spraying, and meanwhile, the soil contains a certain amount of moss (equivalent to 'seeds'), thereby being beneficial to quick greening. If the surface soil is not dried in the sun or in the air, the moss in the moist soil is easy to go moldy and rot.
In step S4, the culture medium in the non-woven fabric ribs comprises the following components in parts by weight: 60-70 parts of mushroom residues, 10-15 parts of garden soil, 10-12 parts of perlite, 4-6 parts of calcium magnesium phosphate fertilizer, 1-3 parts of slow-release compound fertilizer and 1-1.5 parts of super absorbent resin.
When ecological restoration is carried out, the 'stem-broken dry moss' is taken as 'seeds' and is uniformly mixed with surface soil containing moss, a water-retaining agent and an adhesive which are separately stored, and the mixture is placed into a soil dressing spray-sowing machine to carry out soil dressing spray-sowing on a field needing ecological restoration.
In summary, according to the ecological restoration structure and method for quick greening of the slope of the mountain wind farm, the dormant moss is adopted to perform greening after reviving, and compared with the seed growth greening, the survival rate is higher, the growth state is better, so that the ecological greening effect is greatly improved.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
