At present, administering the measure in salt-soda soil has hydro-melioration measure (flushing/shower salt, well row, closed drainage), agricultural
Technical measures (deep ploughing is digged, soaked field is stirred, crop rotation and biological modification are utilized, salt-enduring cultivars seed selection), chemical modifying (gypsum, chlorine
Change calcium, calcium carbonate etc.) etc..On the whole, the modified utilization of domestic and international salinized soil, typically passes through following two aspects:The
One be by improved soil in itself, reduction soil dissoluble, sodium adsorption ratio and basicity are that plant creates good growth
Environmental condition;Two be to utilize biological modification, i.e., by from the salt-enduring cultivars in plant, and bearing of excavating that kind itself has
Resistance to ability, is directly planted in salinized soil afterwards, but these technologies all have " accumulation of salt in the surface soil " phenomenon, and place over time
Manage cost higher.
Littoral plain area has specific geological structure, is fed by shallow embedding mildly saline groundwater, Features of Shallow Groundwater buried depth
Shallow and groundwater flow is nearly at dead state, and vertical evaporation is significantly increased, and turns into main excretion pathway, in addition
Influenceed by marine bed with seawater, tide, salinity is very high in soil layer.Aeration zone is generally silty clay, sand or silt clay
Interaction deposition structure, water salt easily rises to vegetation root system layer or earth's surface under strong evaporation, and plant is due to physiological water shortage
And it is dead, the phenomenon of vegetation degeneration is caused, seawater invasion exacerbates the problems such as salinization of soil, muskeg are degenerated.Therefore lead
The decline of the bio-diversities such as coastal region vegetation or even whole ecosystem degradation aggravation are caused, coastal region life is greatly constrained
The functional rehabilitation of state system.
Electric repairing technique is a kind of efficient, based technique for in-situ remediation just risen for nearly 20 years, and electro reclamation is utilized both at home and abroad
Technical principle, research emphasis is more in heavy metal-polluted soil cation (lead, chromium, arsenic, zinc, cadmium, copper, nickel, mercury, manganese etc.) and organic contamination
In terms of the electro reclamation of thing, and the research for being used for desalination is less, is more common in water treatment applications research, and it is green to be used for beach saline land
