Description
Technical field
The present invention relates to marine solonchak salt discharge technical field, specially a kind of marine solonchak seepage pipe Salt discharge method.
Background technology
Salt-soda soil is a type of salt aggregation, refer to inside soil contained by salinity influence the normal life of crop
Long, according to UNESCO and food and agricultural organization's incomplete statistics, the area in whole world salt-soda soil is 9.5438 hundred million hectares,
Wherein China is 99,130,000 hectares.The formation of China's alkaline earth and alkali-affected soil, it is most of accumulative related with Carbonates In Soil,
Soil pH is generally higher than 8.0, and regional area total soil phosphorus cannot meet higher than 0.5% (part month, numerical value meeting higher)
The growth of most of plant needs, and to build landscape planting engineering in such a situa-tion, must just handle soil issues well, this
It is exactly the meaning of saline land greening engineering.
Utilization with South China to coastal area, corresponding technical measures required for the virescence rebuild in salt-soda soil
Also more and more urgent.The method of alkaline land improving has very much, but the not no operational procedure and method of specification so far.Salt-soda soil gardens
There are many unfavorable factor of greening, and principal contradiction is to contain excessive soluble organic fraction in soil.According to " salt goes come salt with water with water
Salt is with salt waterborne with underwater " characteristics of motion of this water salt, usually the salinity in soil is drained simultaneously with water using irrigation and drainage measure
Rise along capillary interstice under establishing separation layer with blocking saliferous and controls level of ground water below critical depth to reach soil
Desalination and the purpose for preventing the accumulation of salt in the surface soil.The improvement in salt-soda soil is crucial in coastal region saline land greening engineering, alkaline land improving effect
The quality of fruit, is directly related to that can plant survive and can soil property meet the needs of plant growth for a long time, is engineering success or failure
Deciding factor.Though however, this method can obtain certain effect, numerous technical methods showed and construction technology compared with
For lag, salt-soda soil needs 1 year improvement time that could plant trees, slower to China coast Land Resources Exploitation.
Chinese patent mandate publication number：CN104255107B announces a kind of marine solonchak vertical pipe Salt discharge method, the party
Method includes the following steps：1) the smooth and moulding in soil, is carried out first on determining land use for greening；2), smooth good green
On the ground, one interim bright ditch of interval setting, bright ditch width are 50-60cm, and depth is 90-100cm；3), the installation of vertical pipe：
Ready vertical pipe in advance is put into bright bottom of trench, the axial line spacing of adjacent vertical seepage pipe is 5m, at the bottom of vertical pipe
Portion fills a drainpipe, and the drainpipe is directly connected to municipal well or gully；4), bright ditch original soil is backfilled in ditch；5)、
Green land is subjected to second formation and moulding, and overlays the uniform of 10cm thickness more than upper soll layer and has mixed biological modification agent
Original soil soil；Then conventional pouring is carried out, still, there are some defects to be such as unfavorable for towards larger range of shore for the Salt discharge method
Sea salt soil is promoted, moreover, the problems such as cannot adjusting acid-base value and the leak of marine solonchak well.
It is in view of the deficiencies in the prior art and insufficient, it provides that a kind of constructing operation is simple, and economic cost is low, administers salt
Alkali ground significant effect, shortens the salt discharge period, increases the marine solonchak seepage pipe Salt discharge method of plant survival rate, very promising.
Invention content
The present invention provides a kind of marine solonchak seepage pipe Salt discharge method, and used process is as follows：
