Description
Technical field
The present invention relates to a kind of beach saline land low cost, the method for quick ecological reparation, more particularly to a kind of strand weight
Salt-soda soil low cost, the method for quick ecological reparation.
Background technology
It is influenced by coastal seawater and shallow earth's surface, high salinity underground water, often salification is serious for beach saline land, and from seashore
Closer, saline and alkaline heavier, when soil salt content >=30g/kg (heavy saline), earth's surface is exposed, no plant growth.Natural conditions
Under, salinized soil quality improve depend entirely on pionner Suaeda salsa raw and growth, generally to deposit more than for many years, salt
Ground alkali is fluffy to be just able to invade, raw and growth, and the ecological demand of existing urban construction cannot be met.Current beach saline land
It administers the control salt being predominantly combined with " improving the soil ", " filling " and underground " every ", " row " engineering etc., press down salt technology, construction cost height,
Period is long, quantities is big, and the ecology for not being suitable for provisional idle construction land is quickly repaired, therefore there is an urgent need for a kind of strand geavy salt
Inexpensive, quick ecological reparation the technical method in alkali ground.
Invention content
Technical problem to be solved by the invention is to provide a kind of heavy saline-alkali area at seashore low cost, the sides of quick ecological reparation
The technical method that method, especially salt content >=30g/kg heavy saline ecologies are quickly repaired excavates soil mainly by level land grooving
Concentration is stacked at slot side earth's surface and forms ridging area, and overlay film on ridge, the exposed standing of other side earth's surface forms " overlay film ridge-groove-
Plane earth (exposed) " steric environment forms more moistening, a microenvironment for less salt by the induction of mima type microrelief in slot bottom,
Pionner Suaeda salsa is promoted raw, fast-growth method.
In order to solve the above technical problems, the technical scheme is that：
A kind of heavy saline-alkali area at seashore low cost, the method for quick ecological reparation, include the following steps：
(1), prepartion of land；
(2), 25-34cm determining deviations are pressed and carries out city's roads；With four determining deviations for a unit；
(3), in each cell, first determining deviation section indwelling is motionless, and second, the 4th determining deviation section is excavated into
Slot, excavates out in slot to concentrate and is stacked into third determining deviation section, forms ridging area, excavation groove deep 8-12cm, and slot bottom is wide
14-18cm, 90 ° <Close to the sidewall bottom Po Jiao < of third spacing section in slot;120 °, remote adjacent third spacing section in 120 °≤slot
Sidewall bottom slope angle≤135 °, slot bottom are smooth；
(4), for ridging area overlay film to cell wall bottom, film end soil pressure is tight；
(5), slot bottom broadcasts sowing the fluffy plantation of alkali.
In the above method, ridging area described in step (3), soil is pressed with heap with leveling, bat, ridging side wall and following excavation
Groove sidewall is kept in a plane, ridge top width degree 8-30cm.
In the above method, overlay film described in step (4) is transparent polyvinyl chloride (PVC) canopy film of thickness 0.03-0.05mm.
In the above method, fluffy alkali described in step (5) is Suaeda salsa, application rate 4.0-8.0g/m2。
In the above method, heavy saline-alkali area at seashore salt content >=30g/kg heavy salines.
Advantageous effect possessed by the present invention：
1) construction is simple of the present invention, strong operability is of low cost, can be widely applied in beach saline land restoration of the ecosystem,
It is better especially for the heavy saline of soil salt content >=30g/kg, it repairs quickly, the period is short, at low cost (≤20 yuan/
m2), this season Land cover degree can reach 60% or more, significant effect.
2) the technology of the present invention utilizes ridging area overlay film, realizes collection, reflux, the utilization of surface evaporation water, is formed in slot bottom
The water replenishment area more moistened, while using the evaporation of the slot other side exposed earth's surface, by growing area salinity transfer to exposed
Ground table segment forms more suitable " desalination-moistening " microenvironment in slot bottom, promotes Suaeda salsa quick raw and raw
Long, which need not artificially irrigate moisturizing maintenance, greatly saved freshwater resources, reduced maintenance cost, realize weight
The efficient utilization of Resource of Saline Soil, economic, society, obvious environment benefit.
Description of the drawings
Fig. 1 is the live schematic longitudinal section of heavy saline-alkali area at seashore of the present invention low cost, quick ecological recovery technique.
In figure, 1 is exposed level land, and 2 be ridging overlay film area, and 3 be planting groove, and 4 be Suaeda salsa.
Specific implementation mode
With reference to specific embodiment, the present invention will be further described.
A kind of heavy saline-alkali area at seashore low cost, quick ecological reparation technical method, mainly pass through level land grooving, excavate soil
Concentration is stacked at slot side earth's surface and forms ridging area, and overlay film on ridge, the exposed standing of other side earth's surface forms " overlay film ridge-groove-
Plane earth (exposed) " steric environment forms more moistening, a microenvironment for less salt by the induction of mima type microrelief in slot bottom,
Pionner Suaeda salsa is promoted raw, fast-growth technical method.
Embodiment：
Case Experiments On A is in late April, 2016, the industrial area Taida greening group original soil greening examination at Tianjin Southern port
It tests on study base and is unfolded, experimental field to enclose 3 years areas of extra large hydraulic reclamation, area 1000m2(100m × 20m), 0-40cm topsoil saliferous
Amount mean value is 35.7g/kg, pH value 8.43, open ground, no plant life.
A kind of heavy saline-alkali area at seashore low cost, quick ecological reparation technical method, include the following steps：Prepartion of land；
City's roads are carried out by 30cm determining deviations；With four determining deviations for a unit；In each cell, first 30cm sections of indwelling
Motionless, second, the 4th 30cm sections carry out milling slots, and concentration is excavated out in slot and is stacked into third 30cm sections, soil
It is pressed with leveling, bat with heap, forms ridging area, ridging side wall is maintained at following excavation groove sidewall in a plane, ridge top width degree
10cm excavates groove deep 10cm, the wide 15cm of slot bottom, and the sidewall bottom slope angle of remote adjacent third spacing section is 135 °, 90 ° in slot;Slot
The interior sidewall bottom Po Jiao < close to third spacing section section;120 °, slot bottom is smooth；Cover the transparent polyvinyl chloride canopy of 0.03mm in ridging area
Film, until cell wall bottom, tight with soil pressure；By 5.0g/m2Application rate broadcasts sowing Suaeda salsa seed in slot bottom.
Test observation is the results show that earth's surface starts to emerge after planting 18 days, and closer to the film area of coverage, the fluffy emergence of alkali is got over
Together, growing way is better, and after planting 60 days, trial zone ground mulching degree has reached 43.8%, and ground mulching degree reaches after plantation 150 days
68.5%, plant growing way continues well, and check plot earth's surface is exposed, no plant growth, significant effect.
The above described is only a preferred embodiment of the present invention, not making any form to technical scheme of the present invention
On limitation, it is every according to the technical essence of the invention to any simple modification made by above example, equivalent variations and repair
Decorations, in the range of still falling within technical scheme of the present invention.
