Description
Technical field
The present invention relates in Karst region, a kind of side of the implementation method of Pb-Zn deposits impurely stony desertification area's revegetation
Method.
Background technique
Southwestern China Karst region geologic setting is unique, is produced for a long time by strong carbonate rock chemistry corrosion
Earth's surface-underground two layer of space structure, soil layer is shallow and discontinuous, heterogeneous strong, and mankind's activity, which includes that farming is movable, to be interfered just
It is enough to destroy the ecology of Karst region fragility, so as to cause the stony desertification of this area.Generally, stony desertification is in karst
Under fragile ecological environment, the unreasonable socio-economic activity of the mankind, with causing people particularly thorny, vegetation deterioration, soil erosion, rock
Stone is gradually exposed, fertility decline is lost, and the evolution process similar to desertification landscape is visually presented in earth's surface.
The unreasonable land use of the mankind exacerbates this area's soil erosion.Soil erosion declines soil fertility, nutrient
It is lost, so that soil degradation, vegetation degeneration, finally prevent land resource from generating using exacerbation stony desertification.In recent years, one
A little scholars have conducted extensive research the soil physico-chemical property of Karst region, the main soil effect for studying Rocky Desertification Control process
It answers, influence, soil organic matter and the relationship of bulk density of the vegetation degeneration to the soil organism and nutrient etc., this is Karst region
Rocky Desertification Control engineering provide important scientific basis and theory support.Present inventor attempts the research base in forefathers
On plinth, in conjunction with the reparation practice to Karst region many years, it is extensive to provide a kind of effective Karst region stony desertification regional vegetation
Multiple method.
Summary of the invention
To solve the above problems, present inventor provides a kind of Karst region Pb-Zn deposits impurely stony desertification region plant
The method being resumed, comprising the following steps:
(1) there is the float stone of security risk using excavator cleaning removal area to be repaired, carry out prepartion of land；
(2) it is planted trees to the slope surface in area to be repaired less than 60 degree with the tree species of drought-resistant barren scholar's earth；
(3) to 65 degree or more 85 degree in area to be repaired with Caused by Sloping Surfaces, construction personnel sits platform sling from mountain and hangs down, and uses punching
It hits the brill hole drill straight diameter 16mm, pitch of holes 2m in lime stone side slope and squeezes into expansion hook；Slope protection net uses upper and lower diagonal line 3cm, left
The diamond hole wire netting of right diagonal line 6cm puts down wire netting along slope surface from top to bottom, is fixed on expansion hook；Yu Tie
Silk screen surface weave vegetable fibre net, material based on stalk, supplemented by grass fiber, are adjacent to stone side slope surface with branch as far as possible；It will be with
The parent-soil that auxiliary material and vegetable seeds are uniformly mixed is sowed grass seeds by duster onto slope surface and wire netting, and thickness of sowing grass seeds by duster is about 10cm；
(4) to 85 degree or more slope surfaces in area to be repaired, liana is selected to be transplanted；Soil sow grass seeds by duster after on slope
Planting hole is arranged in bottom；Nursery stock dips in root-inducing powder or mud conditioning before transplanting；Nursery stock is placed in planting hole, it is ensured that root system relaxes just,
By nursery stock righting, by nest cheat in filled composite type fertilizer, earthing is treaded, with rubble or litter coverage in surface after compressing；
(5) maintenance management: periodically being sprayed water, reseeded, being applied fertilizer, prevention and control of plant diseases, pest control maintenance, grass seeds budding and Seedling Stage,
It is important to note that water seasoning, the sprinkling fog-like of when watering, during plant is grown into, fertilising in due course and prevention and treatment pest and disease damage.
Further, the tree species of drought-resistant barren scholar's earth include wilson dogwood, and Coriaria sinica is welcomed spring, cuckoo, gleditsia sinensis, Luan Shu,
Bamboo and Ligustrum vicaryi.
Further, the parent-soil be by soil that area to be repaired is nearby formed after month after month weathering throughout the year, clear out a gathering place when production
The sandy soil that raw sandy soil and chad crush, cross the reinforcing bar sieve in the hole 6-8 ㎝, after the chad impurity and soil particle of removing bulk
Mixture.
Further, the auxiliary material is the mixture of fertile soil, compound fertilizer, flour or maize flour and sawdust.
Further, the method for sowing grass seeds by duster in step (3) includes: that 10 cubic meter of water are first poured into hydroseeder, mechanically activated to stir
It mixes, is then incorporated 4.6 cubic metres of parent-soils, 300 jin of fertile soil, 320 jin of compound fertilizers, 120 jin of flour or maize flour, 300 jin is added
Sawdust.
Further, it sows grass seeds by duster the 4.6 kilograms of water-retaining agent of addition in first 2 minutes, asphalt mixtures modified by epoxy resin need to be added in adhesive, 70 degree or more slope surfaces
Rouge regulator.
Further, vegetable seeds and moss and green algae powder are mixed in the soil；Vegetable seeds includes Coriaria sinica, birch
Wood, palm, two color shrub lespedezas, crotalaria mucronata, black chaste tree, chrysanthemum crowtoe, globe daisy Chinese milk vetch, level ground is with rye grass, Festuca Arundinacea, purple sheep
Thatch, alfalfa, safflower, white flower clover, elegant jessamine, Rheum hastatus D. Don, Lysimachia christinae, southwestern fescue grass.
Further, the liana include Smilax china L, spatholobus suberectus, Mucuna birdwoodiana, evergreen mucuna stem, Paederia scandens,
Boston ivy.
A kind of Karst region Pb-Zn deposits disclosed in the present application method that impurely stony desertification regional vegetation restores, according to not
Same terrain slope takes different embodiments, using local dominant plant, constructs complete plant ecological chain,
With with strong points, implementation process is simple and convenient, and repairing effect is stablized persistently, can preferably adapt to the ecological ring of Karst region
, there is important meaning in the advantages of border to preventing erosion, preserving the ecological environment.
