Description
Technical field
The invention belongs to technical field of land improvement more particularly to a kind of salt-affected soil modifying agent and salt-affected soil to improve
Method.
Background technique
Since land resources are in short supply and land resource protective awareness is thin, salination or secondary is had occurred in many soils in China
Salination, with the quickening of urbanization process, a large amount of salt-affected soils need to build for city development.But in construction of city afforestation
In, since salt-affected soil salt content is high, plant recovery of nutrient is poor, limits plant growth, causes to agricultural and forestry production and Urban Greening
Limitation.Many coastal cities expanded by way of reclaiming land from the sea city can using area, this part soil salination also compared with
To be serious, and many decades, even longer time are needed by rainfall elution and succession of plant improvement salinized soil, it is necessary to pass through technical measures
Construction of city afforestation could be used for after carrying out soil improvement.
Soil is the basis of plant growth, and the optimization of soil texture is one of important content of plant cultivation technology, and
The basis of soil management.The soil improvement of science can provide good liquid manure gas thermal environment for plant growth and development, and can
The effective conservation of soil and water reduces the maintenance cost of plant.In decades, country has put into a large amount of human and material resources to be transformed
Coast saline soil.In recent years, industry byproduct desulfurized gesso of flue gas starts the improvement for being applied to salt-soda soil and acceleration is enclosed
It cultivates in the desalination processes in salt-soda soil, improves crumb structure, increase soil water permeability, cut and provide the nutrients such as Ca, S for plant, and
It significantly improves except the functions such as crop yield, most important effect is that a large amount of Ca2+ is provided for soil, can effectively be set
Tradable Na+ in saline-alkali soil is changed, the basicity of soil is reduced.But desulfurized gesso of flue gas itself is only used only and is used as modifying agent
Due to the limitation of its own property, there is also more defects.Since the calcium ion in desulfurized gesso of flue gas can also replace soil
Tradable K+ in earth, additionally it is possible to adsorb the P in soil, reduce available potassium and available phosphate concentration etc. in soil.
Summary of the invention
The present invention provides a kind of method that salt-affected soil modifying agent and salt-affected soil are improved, which can be reduced

Implement the modification method of the present embodiment using the coast saline soil of District of Shanghai, desulfurized gesso of flue gas is near
Certain large coal-fired power plant, garden waste compost comes from Shanghai Botanical Garden.In order to illustrate to apply present invention improvement strand salt
Stain soil has more satisfactory effect, and the modifying agent for devising 6 different levels is horizontal (A1:15 tons/hectare), and (A2:30 tons/public
Hectare), (A3:60 tons/hectare), (A4:90 tons/hectare) (A5:12 tons/hectare), CK (original soil).All processing during test
Same water and fertilizer management, and constantly water to keep soil moisture, guarantee that modifying agent is sufficiently reacted with soil.It is measured respectively after 1 year
The biomass of PH, EC value (soluble-salt content) of soil, nutriment and planting plants, the results are shown in Table 1.
The different modifying agent amounts of application of table 1 handle lower salt-affected soil physicochemical property index
As can be seen from Table 1, being continuously increased with mixed soil modifying agent amount of application, experimental group soil pH relatively compare
Group has significant decrease, and the EC value of soil is increased slightly in lower amount of application, but decreasing trend is presented when amount of application is larger,
Remaining nutriment index such as content of organic matter etc. illustrates that method of the invention can have as the increase of amount of application is significantly increased
Effect improves soil physico-chemical property, reduces coastal soil salt content, and improve soil nutrient content.
Black malt is planted in six numbers experiment soil of test block, as can be seen from Table 2, as mixed soil is improved
Agent amount of application is continuously increased, and the germination percentage of experiment soil plantation rye grass, plant height and biomass etc. have successive group
Increase, so the growth and development of plant can be promoted using the invention.But by Tables 1 and 2 it can also be seen that in higher application
The variation tendency conspicuousness of (90-120 tons/hectare) soil physico-chemical property and plant growth reduces in the case where amount, it is contemplated that material
The reasons such as material expense, it is proposed that the amount of application of 90-120 tons/hectare is the recommendation amount of application of the project.
The different modifying agent amounts of application of table 2 handle the growth indexes of lower rye grass
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode.Even if to the present invention, various changes can be made, if these variations belong to the model of the claims in the present invention and its equivalent technologies
Within enclosing, then still fall within the protection scope of the present invention.
