Description
Technical field
The utility model ecological environment treatment field, it is related to a kind of organic recovery system of salinization of soil.
Background technology
The salinization of soil refers to that soil salt content is too high (more than 0.3%), and makes crops low yield or can not grow.For solution
Certainly saline Land, traditional pattern are to control irrigation water to feed the excess of underground, and level of ground water is limited in into critical depth
Below.In a manner of more drainings of pouring water more, soil is promoted to be converted to desalination direction.Although this method effect is good, and deposits a lot
Problem：(1) in the area polluted compared with polybasic salt, local water resource, which determines, largely to use the water of no salinization of soil to be filled
Irrigate；(2) area lacked relative to water resource can not use the water resource of great number, and then cause this method to be difficult in some areas
Promote；(3) there is the problem of Water Resource Adjustment ＆ Distribution transport, and difficulty of the allotment without saline-alkali water resource.
How scientific research personnel always effectively handles the salinization of soil if exploring, explored by long-term improvement, main at present
There are following several modification methods：(1) Physical, mainly irrigation and drainage and land reclamation, the former is enriched degree by water resource
Limit larger, the latter's quantities is big, and the cycle is longer, and financial cost is uneconomical；(2) chemical method, chemical improvement agent is mainly added,
Such as gypsum, diatomite and organic fertilizer material, to improve soil texture, soil acidity or alkalinity is adjusted, but this method is drawn sometimes
Enter new material, soil and crop are adversely affected；(3) bioanalysis, soil is improved generally by plantation salt tolerant crop
Earth, effect is slower, is influenceed by region and water resources condition.At present, the transformation to salt-soda soil is much that any of the above measure is mutually tied
Close, so as to obtain more significant effect.
CN 106576482A disclose a kind of method of comprehensive regulation salt affected soil, and it is mainly using physically improved and raw
The method that thing improvement is combined is administered, but bioanalysis implantation time is slower, and step is cumbersome, and irrigation water is not repeated into profit
With still being influenceed by water resource；Two kinds of ameliorative measures simultaneously fail to combine well, still suffer from the defects of respective.CN
205623420 U disclose a kind of saline land greening implant system, including kind of planting ditch, from bottom to top filled in described kind of planting ditch every
Absciss layer, aquifer and planting soil layer, while plant in planting ditch and be provided with some sumps, the borehole wall of the sump is by seepy material system
Into bottom wall is provided with water pump, and inwall is provided with liquid level sensor, and both are connected with controller.The implant system can realize the circulation of water
Using with Auto-drainage, but it is required transformation area it is larger, cost is higher；Underground water segregation is also unfavorable for plant growth and water
Overall circulation.
As can be seen here, the method for the existing processing salinization of soil still suffers from problems with：
(1) dependence to water resource is big；
(2) it is larger to region dependence to repair wetland with saline-alkaline；
(3) it is poor for applicability, soil is improved and changed because of water, it is big by season arid or rainy season influence degree.
Utility model content
For problem present in existing processing salinization of soil method, the utility model provides a kind of salinization of soil
Organic recovery system.System described in the utility model is retained using water channel to farmland irrigating water, is collected to sump, is passed through
Set different packing layers to handle irrigation water, adjust its pH value, reduce salinity, irrigation water after treatment can return
Reuse is irrigated.Meanwhile using white-out structure control level of ground water, reduce accumulation of the salt to ground soil in underground water.This
System described in utility model, which can effectively solve salinization of soil of the irrigation water quality on soil, to be influenceed, and rainwater-collecting can be achieved, and water is provided
Source is relative to lack area, can fully realize the utilization of water resource.
To use following technical scheme up to this purpose, the utility model：
The utility model provides a kind of organic recovery system of salinization of soil, and the system includes drainage of soil and collects list
Member and water purification units, are connected between drainage of soil collector unit and water purification units by collection conduit, wherein, drainage of soil

Under be sequentially provided with gypsic horizon, crushed rock filler layer and water purification collecting pit.
In the utility model, after irrigating and soaking, unnecessary water is collected soil by drainage of soil collector unit,
And it is sent into sump and is handled by collection conduit.
The irrigation water collected by collecting pipe is distributed by cloth water channel, irrigation water can be made uniformly to flow into sump, when
Irrigation advance is main that following react occurs through gypsic horizon and during crushed rock filler layer：
Na2CO3+CaSO4=CaSO3+Na2SO4
Na (clay colloid)+CaSO4=Ca (clay colloid)+Na2SO4
When irrigation advance is through gypsic horizon, is mainly replaced exchangeable sodium ion in water by chemical reaction, made sodium matter hydrophilic
Colloid is changed into calcareous hydrophobic colloid.So as to reduce salinity in water, water quality is set to can reach the standard of repetition irrigation.Water after irrigation
While being flowed through in packing layer, irrigation water and the contact area of reaction are increased, extends the reaction time, effectively replace water
Middle sodium salt ion.
After sump uses some cycles, gypsum can be added again, recovers the reactivity of gypsic horizon, while packing layer
Broken sandstone form adsorption bridging effect, filtering retention is carried out to the suspension in water, finally water after salinity simplifies passes through
Reflux pump is promoted to earth's surface and reused, and recirculates and utilizes.
Irrigated by being repeated several times, the salinized soil of earth's surface is gradually repaired.Soil is substantial amounts of to fill during reparation
Water causes part fertilizer loss in soil, and soil texture is affected, and can supplement fertile soil by adding acidic fertilizier,
Soil acidity or alkalinity is adjusted, and adds related vegetation fertilizer, such as cornstalk, recovers soil vitality, while keep soil to exempt from again
