Description
Technical field
The invention belongs to soil improvement fields, and in particular to a kind of modification method in gardens salt-soda soil.
Background technique
Currently, salt-soda soil is the general name of solonchak and alkaline earth and various salinization, alkali-affected soil.Contain in salt-soda soil and largely may be used
There are the sodium ions that saturation degree is excessive on dissolubility salinity or soil colloid, generate harm to plant and edaphon, destroy
Soil texture causes soil hardening, permeability to be deteriorated, in addition the biological toxic action of salt basic ion, crop are unable to normal growth,
It is even dead.In addition, soluble organic fraction is excessively high also to generate antagonism to plant nutrient.Therefore, produce are made in varieties in saline-alkali areas
Amount is not high, and the surrival rate of afforestation is lower, seriously affects varieties in saline-alkali areas economic development and the improvement of ecological environment.
The modification method in salt-soda soil has very much, has including traditional modification method: the desalinization of soil by flooding or leaching levels land, deep ploughs and plough deeply,
Physically improved method has two embrane methods, soil moved in improve the original, pressure sand, and every salt deposit, salt discharging pipe, every salt bag method etc., chemical amendments is mainly useization
Learning substance decrease surface soil alkalinity improves its soil property.
Traditional salt-soda soil pH chemical modifying method is to use such as Sulfur, sulfuric acid, ferrous sulfate, aluminum sulfate acid soil
Earth has residue, such as chloride ion, metal ion etc. after alkaline earth acid adding, while increasing the salinity of soil.Traditional salt affected soil
The method of salinity chemical modifying improves salt-soda soil using gypsum, ardealite, calcium superphosphate, humic acid, peat, acid-sludge etc..At present
Relatively broad application is using gypsum, ardealite, calcium superphosphate, and sexual valence is relatively high, by replacing the sodium ion in salt-soda soil,
Change alkaline earth is sulfate ion, and sulfate is only the 1/5 of carbanion to the harm of plant, and obtained sulfuric acid sodium ion can
To be washed away quickly through hidden pipe salt discharge.This method is disadvantageous in that: 1) gypsum dosage is big, and in gypsum containing more chlorine from
Son, heavy metal ion etc., it is unfavorable to plant growth.2) unobvious using ardealite regulation effect, generally require two trienniums
Crops could be planted, and after applying ardealite processing on slight alkaline land, the germination percentage of crops is still lower and the later period
Growing way is bad.3) using having a large amount of insoluble calcium phosphate in excessive ardealite, it is unfavorable for crop absorption, be easy to cause soil plate
Knot, is not easy to wash out, and the later period burns root burn seedlings phenomenon, is unfavorable for plant growth etc..
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of modification method in salt-soda soil, improves saline alkali, while improving soil
Earth is hardened.
The present invention is achieved by the following technical solutions:
A kind of modification method in salt-soda soil, comprising the following steps:
(1) according to the landscape plant kind to be planted, the planting soil region for needing to improve in salt-soda soil is determined, by alkaline land improving
Agent is uniformly spilled into saline and alkaline ground surface, and amount of application is 15-20Kg/ mus, pours water after then carrying out rotary tillage processing, draining is dried；
(2) by treated, soil conditioner is added in soil region, and amount of application is 1.0-5.0Kg/ mus, is dried after sprinkling irrigation；
(3) the landscape plant kind that plantation needs.
Preferably, the alkaline land modifying agent is the filter residue of beer waste water, the preparation method comprises the following steps:
(1) citric acid waste is added in the beer waste water after fermenting, and additional amount is the 10-15% of beer waste water quality, at stirring
Reason；
(2) wastewater quality 10-15% furfural dregs are added, 0.02% zinc sulfate are added, while wastewater quality 0.01-0.05% is added
Polyvinylpyrrolidone, filtering, obtains filter residue.
Preferably, the soil conditioner the preparation method comprises the following steps: water is added in citric acid waste, make citric acid waste water content
Reach 50%, maleic acrylic copolymer is then added, be warming up to 60-65 DEG C after mixing evenly, malic acid and mistake is then added
Hydrogen oxide continues insulated and stirred 4h, is down to room temperature.
The waste residue that the citric acid waste generates when can produce citric acid for Citric Acid Plant, is divided into the bacterium of filters pressing process generation
The waste residue for the calcium sulfate that filament waste residue and hydrolysis procedure generate, the mycelium waste residue used in modifying agent, and make in conditioner
It is the calcium sulfate waste residues that hydrolysis procedure generates；The furfural dregs are rice husk, poly-pentose contained by cornstalk/core or cotton seed hulls
After hydrolysis obtains industrial chemicals furfural dregs (furtural), the biological material of generation；
Preferably, the additional amount of the maleic acrylic copolymer accounts for the 1-3% of citric acid waste quality.
Preferably, the additional amount of the malic acid and hydrogen peroxide is the 0.02% of citric acid waste quality, malic acid and peroxide
The mass ratio for changing hydrogen is 1:1.
Beneficial effect
The filter residue after wastewater treatment is added in the present invention, shows acidity, can be neutralized with the alkalinity in salt-soda soil, while in filter residue
Citric acid waste can form sodium citrate with the sodium salt in salt-soda soil, can increase the nutrition in soil, it is excessive right to eliminate salinity
In the harm of soil.Polyvinylpyrrolidone can increase the stability of soil.Soil conditioner provided by the invention can drop
In low soil because a large amount of addition citric acid wastes and caused by heavy metal ion content, and by changing in advance to citric acid waste
Property, it is capable of forming the high-molecular compound maleic acrylic sodium with hydrophilic radical.The compound have hygroscopicity strong and
Good rheological characteristic and stability, can be used as water-retaining agent carry out using, improve the permeability and water penetration of alkaline land soil,
It solves the problems, such as hardened and cracking, improves soil texture and physicochemical property, enhance soil water-reataining fertilizer-keeping ability, avoid moisture
Excessive evaporation drives salinity rising to cause the soil accumulation of salt in the surface soil.
There is insoluble calcium salt in the citric acid waste in soil conditioner in the present invention, by the way that maleic acrylic is added
Copolymer and malic acid and hydrogen peroxide can effectively remove insoluble calcium salt, can be avoided in salt affected soil because of a large amount of additions
Citric acid waste and caused by heavy metal ion content increase.
