Description
Technical field
The invention belongs to technical field of land improvement more particularly to it is a kind of repair soda type saline-alkali soil soil conditioner and
Preparation method and application method.
Background technology
Salinity composition is with Na in soda type saline-alkali soil2CO3、NaHCO3Based on, it is in strong basicity, pH value is up to 8.5, serious area
More than 10.5, plant growth is seriously hampered.Salt affected soil is carried out at the same time alkali process, salt accumulation in surface soil mistake with saliferous
Journey, basicity is high, in alkalinity and strong basicity reaction.Therefore, the harm of soda type saline-alkali soil is not only in that salinity height, and alkalinity is also very
By force, it is extremely difficult to administer.
Nowadays the characteristics of being according to " salt comes with water, and salt is gone with water " mostly about the improvement of saline-alkali soil, control moisture steams
Hair mitigates salt accumulation in surface soil, and reduces soil pH value and salt content, to reach improvement purpose.Therefore water resources industry is basic
Ameliorative measure.According to moisture-salt transport rule, perfect irrigation and drainage system is established, the salinity in soil is drained with water, and control ground
Lower water level, prevents the accumulation of salt in the surface soil.But water resources industry often has limitation, is not appropriate for the improvement of water-deficient area salt affected soil.
By some agronomic measures, such as level land, rake the soil level, ridging, subsoiling deep ploughing, microcell improve the soil, Soil building,
Change soil physics structure to regulate and control soil water-stable aggregates movement, creates good soil surface state and topsoil construction, promote soil
Desalination；Or by ground mulching, soil water evaporation is effectively reduced, inhibit the soil accumulation of salt in the surface soil, reduces soil salinization degree.But
For the more serious area of saline and alkaline situation, agronomic measures take effect slowly, and reclamation result is bad.
Biological control measure is one of most economical, effective and sustainable method in reclamation of salinep-alkali soil method.Adaptation to local conditions selects
Plant saline alkali tolerant plant, salt tolerant green manure crop, microbial-bacterial fertilizer etc., less investment, high financial profit.But biological control measure is suitable to biology
Answering property is more demanding, similarly there is the slow defect that takes effect.
Applied chemistry modifying agent, thus it is possible to vary soil aggregate structure reduces the soil weight, increases aeration porosity, accelerates
Alkali process is arranged in the desalinization of soil by flooding or leaching；Soluble base composition can also be changed, increase base exchange capacity, improve soil replacement amount and resiliency,
Reduce basicity.Saline-alkali soil chemical improvement agent is broadly divided into calcareous material, acidic materials, macromolecule polyalcohol and other improvement at present
The types such as agent.Most chemical modifying measures only by exchangeable sodium ion exchange in soil at soluble sodium ion, therefore also need
Cooperation water resources industry elutes sodium ion or biological control measure fixes sodium ion.
Therefore, the soil conditioner for developing economical and practical reparation soda type saline-alkali soil has become people in the art
Member's urgent problem.Improvement to soda type saline-alkali soil ecological environment, regional agriculture, society and Ecological Sustainable Development are all
It is of great significance.
