Description
Technical field
The present invention relates to a kind of method for recovering vegetation on rock hillside, especially a kind of high steep rock hillside revegetation structure
It builds body and its restores implantation methods.
Background technique
Green work answer all to the slope surface of abandoned mine both at home and abroad at present has on the more slow hillside of some gradients and is certain
Effect, and to some high steep rock slopes, what traditional soil moved in improve the original spray slope technology was difficult for a long time to consolidate soil moved in improve the original is bonded in smooth
Rock surface, the later period, there are the landslides of larger area and the danger collapsed.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high steep rock hillside revegetation constructs, and apply the structure
Body is built to restore the method for artificial vegetation on high steep rock hillside.
Realize the technical scheme is that
A kind of high steep rock hillside revegetation construct, the construct includes the geotechnique on rock hillside upper layer
Cell compartment, the dimensional metal mesh positioned at geotechnical grid upper layer are filled up in the space that the geotechnical grid is constituted with dimensional metal mesh
Artificial soil and stereoscopic multi-layer time vegetation positioned at artificial soil upper layer.
The geotechnical grid is made of high-intensitive high density polyethylene (HDPE) (HDPE) material, is three-dimensional netted cell compartment knot
Structure, the specification of each cell compartment is 25cm*25cm, high 15cm, and the hole that 15-20 diameter is 1cm is opened in the side of each cell compartment.
Play the role of further storing soil moved in improve the original.
The dimensional metal mesh is made of zinc-plated wire material, and overall dimensions 1.5*1.0m, each specification room is
7cm*7cm, the staggered position rotary of steel wire is at mesh, mesh diameter 2.8mm.Play the work for further fixing geotechnical grid
With.
The artificial soil, that is, soil moved in improve the original material: microbial organic fertilizer, NPK are added after being sieved according to local loam or mellow soil
Compound fertilizer, rice husk, water-retaining agent obtain after being mixed with the ratio of 70%:15%:3%:7%:5%.
The stereoscopic multi-layer time vegetation selects well developed root system, and taking root property is strong, drought-resistant, cold resistance, impoverishment tolerant, disease and insect resistance
Strong kind, in conjunction with the weather conditions and engineering practice of this area, it then follows in due course principle suitablely, multiselect is with shrub, beans
Section plant and indigenous plant kind.

Step 8, seedling stage maintenance: after seed sprouting, watering daily at least once, can be adjusted according to same day weather condition and be poured
Waterside number.Sprinkling fog-like is answered when watering, guarantees being sufficiently humidified so as to for soil matrix；Sprinkler operation preferably carries out sooner or later, forbids in
It is carried out after morning；Periodically fertilising job requirement carries out fertilizer supplement work according to vegetation growth state in due course；Seedling stage will have profession
The daily routine observation of personnel, discovery pest and disease damage are prevented and treated in time；Grass seeds, which is sowed grass seeds by duster, completes the latter moon, should check that grass planting grows feelings comprehensively
Condition gives after-culture to obvious non-uniform position is grown.
Technical effect of the invention:
1, the design of geotechnical grid: using breaking the whole up into parts, change greatly small thought, it is suitable that large stretch of area is separated into size
Cell compartment, reduce the risk that collapses of soil moved in improve the original.And between cell compartment and cell compartment be that hole is connected, will not influence plant root growth and
Water and nutrient is exchanged with each other, and provides advantage for subsequent plant growth.And the height of cell compartment reaches 15cm, can provide and fill
The space of foot is stored for soil moved in improve the original, thus be conducive to vegetation, the growth of especially short arbor.Meanwhile high density polyethylene (HDPE)
(HDPE) the cost of material is low and is easy to be laid with.
2, the design of dimensional metal mesh: overlaying smaller dimensional metal mesh on the upper layer of geotechnical grid, first is that reinforcing
Fixation to geotechnical grid and soil moved in improve the original.Second is that big geotechnical grid is divided into smaller metal cell compartment.Third is that galvanized metal net
Soil can be enhanced to the corrosiveness of iron wire, so as to improve the long-term effectiveness of the system.
3, artificial soil: raw material are easily obtained, and configuration is simple, and cost is relatively low, are conducive to the universal of work.
4, stereoscopic multi-layer time vegetation: using the collocation of the system of taproot and the system of fibrous root, the collocation of draft and shrub is conducive to soil
Fixation.The fixed nitrogen crop such as clover of addition can provide sufficient nutrient for subsequent plant growth.Draft shrub and short
The collocation of dungarunga can more promote the building of plant population and the stabilization of the ecosystem.
5, overall structure bring advantage: for this method by geotechnical grid, metal three dimensional network and artificial soil constitute one
A entirety, but be the unit of oneself again simultaneously, not only it is related but also has any different between the two.It to the eye, is that a structure is non-
The entirety of normal more stable and stronger, still, the geotechnical grid of bottom will integrally be divided into cell again.But between cell compartment and cell compartment again
It is interconnected, a unified organic rock-soil-microorganism-vegetation system is constituted by the root growth of plant.
6, the advantage of implantation methods: due to constructing organic rock-soil-microorganism-vegetation system, construction is simple,
Soil microbial activities in geotechnical grid are stronger, vegetation high survival rate, once forming, can remove the time-consuming expense of later period water wasting from
The maintenance of power；The system can also pass through microorganism from atmosphere from fixed nitrogen by the fixed nitrogen crop such as clover and clover
Decomposition, it is continual that sufficient nutriment is provided for whole system, be conducive to the succession of vegetational type；The system
It is particularly suitable for the high gradient or smooth rock mountain face is formed steady and sustained system, provided by the operation of itself system
Multiple green successful probability and reduction visual pollution.
