Abstract
The present invention relates to a kind of strand hydraulic reclamation geavy salt alkali open ground vegetation fast construction method, this method comprises the following steps：(1), prepartion of land；(2) crushing straw of 0.5 2.0cm length, is laid, 5 8cm stalks is often laid, is rolled back and forth 24 times using 10 15t weight real machines, spray water, repeat laying crushing straw and roll spray water, untill stalk thickness reaches 8 15cm after the compacting, spray water, stop laying；(3), by 120 150g/m2Amount, the fluffy seed of alkali is mixed thoroughly with fine sand or sieving fine earth, broadcasted sowing；(4) 1.0 2.0cm fine sands, are laid.The application of achievement of the present invention rapid build vegetation system, this season vegetation coverage can may be up to more than 60% on the geavy salt alkali open ground of hydraulic reclamation then, and Second Year can reach more than 80%, greatly shorten the alkali fluffy invasion time.
Description
Technical field
The present invention relates to a kind of vegetation fast construction method, more particularly to a kind of strand hydraulic reclamation geavy salt alkali open ground vegetation is fast
Fast construction method.
Background technology
Strand barged-in fill is the warp that is formed using the seabed mud that offshore dredging comes out by waterpower hydraulic reclamation.By seawater
Environment influences, and barged-in fill salt content height (>=10g/kg), alkalescence is strong (pH >=8.0), and particle is thin (based on sticking grain), water-holding capacity
Greatly, invalid hole water content is high, and quality clings, and plant is difficult to survive.Because vegetation is rare, earth's surface is exposed, airborne dust takes place frequently, to area
The ecological environment and health in domain bring great destruction.Existing original soil improvement and soil moved in improve the original planting technique cost height, cycle
Long, maintenance task weight, is not suitable for the reserved hydraulic reclamation open ground restoration of the ecosystem construction of provisional urban construction.Therefore, strand hydraulic reclamation weight
Saline and alkaline open ground needs a kind of technical method of inexpensive, quick vegetation construction badly.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of strand hydraulic reclamation geavy salt alkali open ground vegetation rapid build side
Method, especially salt content >=20g/kg geavy salt alkali hydraulic reclamation open ground vegetation fast construction methods, mainly by hydraulic reclamation open ground
Earth's surface " ground levelling-laying stalk-roll-spray water-sow-cover sand " pattern, realize that strand hydraulic reclamation open ground vegetation is fast
Fast construction method.
To solve above-mentioned technical problem, the technical scheme is that：
A kind of strand hydraulic reclamation geavy salt alkali open ground vegetation fast construction method, comprises the following steps：
(1), prepartion of land；
(2) crushing straw of 0.5-2.0cm length, is laid, often lays 5-8cm stalks, using 10-15t weight real machine back and forth
Roll 2-4 times, spray water, repeat laying crushing straw-roll-spray water, stalk thickness reaches 8- after compacting
Untill 15cm, spray water, stop laying；
(3), by 120-150g/m2Amount, the fluffy seed of alkali is mixed thoroughly with fine sand or sieving fine earth, broadcasted sowing；
(4) 1.0-2.0cm fine sands, are laid.
In the above method, stalk described in step (2) is maize straw.
In the above method, rolling compaction machine described in step (2) is steel wheel formula, and it is 5-10m/min to roll gait of march.
In the above method, spray water described in step (2) is sprayed for artificial or machinery, amount of application：Terminate last before laying
Water-spraying amount is 20-45L/m2, each layer laying fountain height is 10-15L/m under remaining2。
In the above method, fluffy alkali described in step (3) is Suaeda salsa.
In the above method, fine sand described in step (4) is 40-70 mesh river sands.
Present invention also offers the above method in salt content >=20g/kg geavy salt alkali hydraulic reclamation open ground vegetation rapid builds
Application.
Beneficial effect possessed by the present invention：
Strand barged-in fill salt content is high, alkalescence is strong, and quality clings, and structural difference, typically at least to deposit more than 3 years, first
Cutting edge of a knife or a sword plant Suaeda salsa just starts to invade, but biomass is extremely low, and the application of achievement of the present invention can be naked in the geavy salt alkali of hydraulic reclamation then
Rapid build vegetation system on open country, this season vegetation coverage may be up to more than 60%, and Second Year can reach more than 80%, greatly
Shorten the alkali fluffy invasion time, enhance the restoration of the ecosystem of hydraulic reclamation open ground, easy construction, strong operability, cost is cheap,
The extensive application of agricultural stalk simultaneously, decrease maize straw and burn the heavily contaminated problem brought, realize agricultural stalk
Recycling, environment, social and economic benefits are notable.
Embodiment
With reference to specific embodiment, the present invention will be further described, but does not limit protection scope of the present invention.
A kind of technical method of strand hydraulic reclamation geavy salt alkali open ground vegetation rapid build, mainly by hydraulic reclamation open ground
Table " ground levelling-laying stalk-roll-spray water-sow-cover sand " pattern, realize that strand hydraulic reclamation open ground vegetation is quick
The technical method of structure.
Embodiment：
Case Experiments On A is in mid-April, 2016, the industrial area Taida greening group original soil greening examination at Tianjin Southern port
Test on study base and deploy, be experimental field the deposition strand reclaimed land of 3 years, area 900m2(30m × 30m), 0-40cm tables soil
Layer salt content average is 33.7g/kg, pH value 8.27, open ground, no plant life.
A kind of strand hydraulic reclamation geavy salt alkali open ground vegetation fast construction method, specific implementation step are：
Experimental field prepartion of land；The crush maize stalk of 0.5-1.5cm length is laid, often lays 5-6cm thickness stalks, is used
12t weight steel drum compactors roll 3 times back and forth, and it is 6m/min to roll gait of march, artificial spray water, repeats laying and crushes
Stalk-roll-spray water, untill stalk thickness reaches 10cm after the compacting, stop laying, wherein, terminate last before laying
Water-spraying amount is 35L/m2, each layer laying fountain height is 12L/m under remaining2；By 135g/m2Amount, by the fluffy seed of alkali with
Fine sand is mixed thoroughly, broadcasted sowing；Lay 1.0cm thickness 40-70 mesh river sands.
In mid-May, 2016, experimental field earth's surface be covered with the blocks of glossy and green fluffy seedling of alkali, mid-August, experimental field earth's surface plant
Reach 62.8% by cover degree, do not done the check plot of experimental test processing, earth's surface is exposed, one layer of salt efflorescence of earth's surface；In in Augusts, 2017
Ten days, experimental field alkali it is fluffy plantation processing coverage reach 86.3%, check plot still earth's surface is exposed, without any plant growth.This skill
Art is in face significant effect.
The above described is only a preferred embodiment of the present invention, not make any form to technical scheme
On limitation, any simple modification that every technical spirit according to the present invention is made to above example, equivalent variations are with repairing
Decorations, in the range of still falling within technical scheme.
