Abstract
The utility model provides an environment-friendly salt removing system for saline-alkali soil, comprising a saline-alkali isolation layer, a separation layer, a fertilizer-soil mixed layer, a salt discharging pipe and a planting soil layer, wherein the saline-alkali isolation layer, the planting soil layer, the separation layer, the fertilizer-soil mixed layer and the salt discharging pipe are laid on the saline-alkali soil layer from bottom to top in sequence. The environment-friendly salt removing system for the saline-alkali soil has the advantages and beneficial effects serious saline-alkali soil can be greened and planted with plants, the laying operation is simple, a water resource is saved, and especially materials for making of the separation layer are environment-friendly materials, and a greening planting layer is effectively prevented from being salinized. The environment-friendly salt removing system for the saline-alkali soil is applicable to greening and planting for a long time.
Description
Technical field
The utility model relates to the landscape engineering technical field, especially relates to the local greening in a kind of saline land soil layer salt discharge system.
Background technology
The saline land is meant the soil salinization of soil, and promptly the contained salinity in soil the inside has influence on the normal growth of crop, when soil salt content reaches 0.1-0.6%, can be considered the saline land, and it is third-class to be divided into slight, moderate and severe.The survival rate of plantation plant is relatively low in saline lands at different levels, and especially in landscape engineering, in case geology is the saline land, plant survival rate is low, and the greening difficulty is very big.
On the saline land, carry out planting technique; General processing method is at first carried out salt discharge and is pressed salt method etc. the saline land exactly; But above method still comes with some shortcomings; As to press the salt method be to utilize natural precipitation or artificial a large amount of the irrigation, impel the part salinity along the hole of soil, crack etc. to underground infiltration, take the soil salt on top layer to the soil bottom through water; Thereby the salt discharge method is to rely on to use a large amount of fresh water the saline land to be washed away for a long time the salt content attenuating that makes the top layer, saline land; Above method nearly all will use a large amount of water sources; Simultaneously long-term result of use is not good; Especially in the salt discharge method; Mostly be laid on the afforested areas bottom, intercept saline and alkaline effect to face of land infiltration to play with geomembrane HDPE film, but this method cracky and long-term a large amount of easy contaminated environment of using in construction.Therefore a kind of plantation soil layer salt discharge system that water resource, simple and easy to do while again can be permanently effective that saves is badly in need of in the especially heavy saline land greening construction in saline land.
Summary of the invention
In order to overcome the above problems, the invention provides to heavy saline land greening, use simply, can effectively save water resource, can long-term environmental protection effectively plant soil layer salt discharge system simultaneously.
The technical scheme of the utility model is: a kind of saline land environmental protection salt discharge system comprises saline and alkaline separation layer, salt discharge pipe, interlayer, loam mixed layer, plantation soil layer.Said saline and alkaline separation layer, salt discharge pipe, interlayer, loam mixed layer, plantation soil layer are established on upper berth, saline and alkaline stratum from the bottom to the upper strata successively.Wherein the salt discharge pipe buries and is layered in the saline and alkaline separation layer, and saline and alkaline separation layer, interlayer, loam mixed layer, plantation soil layer are passed in the two ends of salt discharge pipe, basset, and fill stone nitre in the salt discharge pipe.
Saline and alkaline in addition separation layer mainly uses stone nitre by one or more are formed in cinder, stone, the stone nitre.
Interlayer is a bentonite bed, replaces the HTPE film of common use.Bentonite has good hygroscopicity, has cohesiveness with water, mud fusion, also is to have strong adsorption function simultaneously, is a kind of Nantural non-toxic, easy to use and expensive few environment-friendly material.As interlayer; Through moisture expantion and absorption exchange interaction not only can effectively prevent saline and alkaline in the saline land through soil, moisture penetration to loam mixed layer and plantation soil layer but also can promote water and the phreatic exchange under the pouring of the face of land; Have certain gas permeability simultaneously, can well satisfy the permanently effective growth that plantation soil layer medium green is planted.
Advantage that the utlity model has and good effect are the planting technique for heavy saline land, lay simply, can effectively prevent the planting technique layer by salinization of soil when saving water resource, and can permanent being applicable to plant.
Description of drawings
Fig. 1 is the structural representation of the utility model;
1. saline and alkaline separation layer 2. salt discharge pipes 3. interlayers 4. loam mixed layers
5. plant and plant soil layer
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, implement greenly when planting soil layer environmental protection salt discharge system in heavy saline land, at first afforested areas is excavated smoothly, lay saline and alkaline separation layer 1, salt discharge pipe 2, interlayer 3, loam mixed layer 4, plantation soil layer 5 then successively from the bottom to top successively.Plant is put into plantation soil layer 5, and backfill planting soil and layering are treaded.
Wherein salt discharge pipe 2 buries and is layered in the saline and alkaline separation layer 1, and saline and alkaline separation layer 1, interlayer 3, loam mixed layer 4, plantation soil layer 5 are passed in the two ends of salt discharge pipe 2, basset, and fill stone nitre in the salt discharge pipe 2.
Saline and alkaline in addition separation layer 1 is made up of cinder, stone and stone nitre etc., mainly uses stone nitre, and the thickness that saline and alkaline separation layer 1 is laid is about 15-25cm.What interlayer 3 was laid is bentonite bed.
Above embodiment specifies the utility model, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (3)
1. saline land environmental protection salt discharge system; It is characterized in that comprising saline and alkaline separation layer, salt discharge pipe, interlayer, loam mixed layer, plantation soil layer, said saline and alkaline separation layer, salt discharge pipe, interlayer, loam mixed layer, plantation soil layer are established on upper berth, saline and alkaline stratum from the bottom to the upper strata successively; Wherein interlayer is a bentonite bed.
2. according to the said salt discharge of claim 1 system, wherein the salt discharge pipe buries and is layered in the saline and alkaline separation layer, and saline and alkaline separation layer, interlayer, loam mixed layer, plantation soil layer are passed in the two ends of salt discharge pipe, basset, and fill stone nitre in the salt discharge pipe.
3. according to the said salt discharge of claim 1 system, wherein saline and alkaline separation layer is by one or more are formed in cinder, stone, the stone nitre.
