Description
Technical field
The invention belongs to sticky salt affected soil to improve field, and in particular to one kind promotes sticky salt affected soil, and quickly elution is de-
The method of salt.
Background technology
Irrigation leaching is the important engineering technology means of salt affected soil improvement.But for the solonchak of clayey texture, glue
The bad soil texture of weight seriously constrains the efficiency infiltrated efficiency, reduce Leaching and desalinization of elution moisture.It is how effective
The structure for improving clayey soil is the key point of the type soil improvement.
In conventional research, using texture modifier, application of organic fertilizers, plough deeply the processing modes such as soil and obtained extensively
Concern.But the mode of ameliorating of existing way exists or treatment cost is high, or the defects of quantities is big.
The content of the invention
The shortcomings that it is an object of the invention to overcome in the prior art, there is provided one kind promotes sticky salt affected soil quickly to elute
The method of desalination.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of method for promoting the sticky quick Leaching and desalinization of salt affected soil, comprises the steps：1) viscosity of improvement is treated
Salt affected soil carries out earth's surface arrangement；
2) irrigate sodium bicarbonate solution and carry out first time elution；
3) after treating that sodium bicarbonate solution infiltrates, irrigate dilute acid soln and carry out second of elution.
4) after treating that dilute acid soln infiltrates, irrigate clear water and carry out third time elution；
5) sticky salt affected soil salt content is determined；
6) if step 5) test salt content it is unqualified if return to step 4) irrigate clear water eluted, and so on
Until salt content is qualified.
The mass concentration of described sodium bicarbonate solution is less than 30g/L；The molar concentration of described dilute acid soln is 0.1-
0.5mol/L。
The mass concentration of described sodium bicarbonate solution is 15g/L；The molar concentration of described dilute acid soln is 0.2mol/
L。
The sticky saline-alkali soil territory table that step 1) includes treating improvement is flattened and sets cofferdam in plot surrounding；
The height in described cofferdam is higher than more than the head height 5cm of irrigation leaching, and the head height of described irrigation leaching is 5-
20cm。
The head height of irrigation leaching sodium bicarbonate solution is determined by the purposes in the improvement plot；For planting herbaceous plant
Plot be 5cm；Plot for transplanting shrub is 10cm；Plot for transplanting arbor is 20cm.
The head height of irrigation leaching sodium bicarbonate solution and the water of irrigation leaching dilute acid soln in step 3) in step 2)
Grease head highness is identical；The head height of irrigation leaching sodium bicarbonate solution is more than or equal to irrigation leaching in step 2) in step 4)
The head height of sodium bicarbonate solution.
Described dilute acid soln is watery hydrochloric acid or dilution heat of sulfuric acid.
Compared with prior art, the beneficial effects of the invention are as follows：
The invention provides a kind of method for promoting the sticky quick Leaching and desalinization of salt affected soil, integrated use irrigation with saline water,
The technological means such as substep elution, degree of saltiness combination, with acid-base reaction " aerogenesis life hole " for core, itself contain in sticky salt affected soil
Carbonate, on the basis of bicarbonate, consider that artificial input bicarbonate solution improves soil body bicarbonate radical content, then borrow
Help others to irrigate dilute acid soln so that a certain degree of acid-base neutralization reaction occurs in salt affected soil, and then utilizes acid-base reaction
The overflow process of generated bubble, the pore structure of soil is formed, structure is provided for the quick moisture Leaching and desalinization process in later stage
Basis, and then promote the method for Leaching and desalinization efficiency, agricultural industry development and improvement of the ecological environment tool for Saline Region
There is important meaning.Specifically：(1) present invention helps lend some impetus to the lifting of sticky salt affected soil irrigation leaching speed, saves significantly
Save the elution time；The raising of Leaching and desalinization efficiency can be promoted, the elution efficiency of unit water is substantially improved.(2) present invention is defeated
The solution concentration entered is relatively low, and contained element is the leading ion in salt affected soil, and secondary dirt will not be caused to salt affected soil
Dye.(3) present invention need not carry out the processing such as deep layer is turned over, material mixes to sticky salt affected soil, save quantities, save
Treatment cost.
Embodiment
In order that those skilled in the art more fully understand technical scheme, implement with reference to optimal
The present invention is described in further detail for example.
Embodiment 1：The sticky solonchak in strand land reclamation area is taken to carry out irrigation leaching desalination experiment, soil pH value used is
