Description
Technical field
The present invention relates to technical field of land improvement, and in particular to a kind of saline alkali soil conditioner.
Background technology
Saline-alkali soil is the general name of solonchak and alkaline earth and various salinization and alkali soil.Wherein, solonchak refers to containing largely may be used
Dissolubility salt and prevent most plants from the soil that grows, salt content is typically up to 0.6% or more；Alkaline earth refers to Sodium by substitution
The percentage (ESP) of ionic cation replacement amount is more than 20% strong basicity soil.The physics and chemical property of salinized soil all compared with
Difference is mainly shown as that salinity or basicity are excessively high, leads to root system of plant water shortage or is poisoned, the viscous weight of the soil texture, aggregate
Less, soil hardening when arid is permeable, gas permeability is poor, totally unfavorable to agricultural production.
For this purpose, being retrieved to Chinese patent literature.In Chinese patent application document " saline-alkali soil conditioner and its preparation

Table 3
Can be seen that saline alkali soil conditioner of the present invention from 3 test result of table can reduce the pH value of soil, and increasing soil has
Machine matter alkali-hydrolyzable nitrogen, available phosphorus, effective potassium content, and better than the saline alkali soil conditioner of the prior art, meanwhile, by comparative example 3-6
Test data be modified processing, addition calcium activator and composite bacteria agent it is found that ardealite carries out calcination processing, zeolite
The pH value for reducing soil, the purpose for increasing soil organism alkali-hydrolyzable nitrogen, available phosphorus, effective potassium content can be played.
The content of beary metal detection to dissociate in 4.4 soil
Table 4 is the salt affected soil conditioning by the saline alkali soil conditioner and comparative example 1-6 of the present embodiment 1-5 of the present invention
The content of beary metal (mg/kg) to dissociate in soil after agent improvement.
Table 4
Saline alkali soil conditioner of the present invention is can be seen that from 4 test result of table can reduce effective heavy metal in soil contain
Amount, and better than the saline alkali soil conditioner of the prior art, meanwhile, by the test data of comparative example 3-6 it is found that ardealite is forged
Burning is handled, zeolite is modified processing, addition calcium activator and composite bacteria agent can play effective heavy metal in soil
The effect of content.
In conclusion creative major embodiment the following aspects of the present invention：
(1) modifying agent of the invention has the advantages that the improvement saline-alkali soil time is short, quick, and can improve severe salt
Alkaline earth.
(2) modifying agent of the invention can reduce saline-alkali soil pH, basicity, the soil weight, exchangeable sodium, improve saline-alkali soil
Physicochemical property, meanwhile, after the modifying agent for applying the present invention, organic matter, alkali-hydrolyzable nitrogen, available phosphorus, effective potassium in saline-alkali soil contain
Amount is improved, and the nutrition condition of saline-alkali soil is significantly improved.
(3) present invention utilize calcined phosphogypsum and calcium activator itself acidic nature, in can occurring in saline-alkali soil with
Reaction, to reduce rapidly soil pH, and ardealite is into crossing calcination processing, the increased activity of itself, in addition, in ardealite
Calcium can effectively exchange the sodium adsorbed on soil colloid through calcium activator activation process, make the reduction of soil exchangeable sodium content, to
Reduce the basicity of soil so that the strong basicity of soil is improved, and such soil colloid can form microaggregate so that salt
The air-and water-permeable performance of alkaline earth is improved.
