Abstract
The invention discloses surfactant reduction the soil salinization in application and method, comprise the concrete steps that：By surfactant formulatory into spray solution in soil, or surfactant directly mixed with soil.The surfactant is any one or a few the mixture in nonionic surface active agent, anionic surfactant, cationic surface active agent, amphoteric surfactant, bion surfactant.The present invention is simple to operate, applied widely, can improve soil property well, reduces soil salt, reaches the purpose of the reduction soil salinization.
Description
Technical field
The present invention relates to surfactant reduction the soil salinization in application and method, belong to Saline-alkali Field Control technology
Field.
Background technology
The soil salinization refers to that the salinity of soil bottom or underground water rises to ground surface with the capillary in soil aperture,
After moisture evaporation, make process of the salt accumulation in topsoil；Also phenomenon or mistake that ease of solubility salinity is accumulated in upper soll layer are referred to
Journey, also referred to as salinization of soil.Incomplete statistics as shown by data according to UNESCO and food and agricultural organization in 2005 is complete at present
The area in world salt-soda soil is 8 × 103Ten thousand hectares.For China, the land area shared by salt-soda soil is up to 3.6 × 103Wan Gong
Hectare.From Northeast plain to Qinghai-Tibet Platean, there is the distribution in salt-soda soil from Northwest inland to East Coastal.In arid, half-dried nonirrigated farmland
Area, the salt-soda soil produced by widely distributed modern salification process；Pediment plain, ancient fluvial terrace and plateau in arid area
On, the various remnants of still visible early formation；In coastal region, due to being influenceed by Seawater immersion, various strands are dispersed with
Solonchak and sulphate soil.The salt-soda soil in inland plain area is mainly distributed on the Junggar Basin in Xinjiang, Tarim Basin, told
Shandong kind basin, the Hexi Corridor in Gansu, the Caidamu Basin in Qinghai.Yinchuan Plain in Ningxia, Hetao Plain, Inner Mongolia, Shanxi
Datong Basin, Xinzhou―Dingxiang basin, Fen Weihe River paddy level land, the Haihe Plain in Hebei, the song-Nen plain in northeast etc. also have in flakes saline and alkaline
Ground or the salt-soda soil being sporadicly distributed.
Soil salinization problem gets more and more people's extensive concerning all the time, and saline-alkali soil is due to higher pH value, containing
There is salinity, the absorption of Plant To Nutrient element can be influenceed, cause impaired plant tissue, destruction soil granular structure and change other
The unfavorable factors such as physicochemical property, are suppressed the normal growth and development of plant, in addition can cause plant wither here or it is withered.At present
Domestic and international alkaline land improving technology, which is summed up, can substantially be divided into：Physics, chemistry, hydraulic engineering, biological four aspects.Its
In, physically improved technology mainly salt-soda soil ground grading, deep ploughing are turned up soil soil, loosen the soil in time, raise landform, microcell and improve the soil improvement
Soil texture, accelerates to drench salt, prevents and treats anti-salt, such as CN200910074228.4, CN200810159999.9,
CN201410430266.X etc.；Chemical modifying technology is to apply chemical improvement agent into soil（Such as gypsum, ardealite, sulfurous acid
Calcium, calcium superphosphate）Pass through chemical action or replacement effect reduction soil salt content.Gypsum, ardealite, calcium sulfite, peroxophosphoric acid
After calcium is manured into soil, the solubility calcium of abundance can be provided for soil, sodium ion in colloidal complex is replaced out, so as to reduce
The salt content of soil, such as CN201410603005.3, CN201510995166.6；Hydraulic engineering improving technology is using big
The fresh water of amount is rinsed to salt-soda soil, the salinity in saline-alkali soil is dissolved in water, then by underground piping draining, by salinity band
Go out, so that the salt content of soil is reduced, such as CN201310331320.0, CN200510044210.1, CN89108061.9；
Bioengineering improving technology on saline-alkali soil mainly by planting salt tolerant crop（Such as corn）, plantation salt-tolerant plant（Such as sesbania）
Or microorganism is delivered, crop, plant, microorganism is absorbed the salt in soil, so as to reduce the salt content of soil, such as
CN200910074228.4, CN201310466328.8 etc..Although these improving technologies can reach certain improved effect, change
Good time length and be difficult maintenance initial stage improved effect, it is difficult to popularize in an all-round way.
At present, surfactant is mainly used in repairing the contaminated soils such as polycyclic aromatic hydrocarbon, Polychlorinated biphenyls, heavy metal, such as
CN201510271339.X, CN201310423166.X, CN201010135665.5, CN201310153637.X etc., there is no by
Surfactant as reduction soil salinized soil modifying agent report.
The content of the invention
The invention discloses surfactant reduction the soil salinization in application and method, by soil apply table
Face activating agent reaches the purpose of the reduction soil salinization.Its mechanism is：Salinity in saline-alkali soil is mainly due to underground water capillary
