Description
Technical field
The invention belongs to Saline-alkali Field Control technical field, and in particular to a kind of moderate saline-alkali soil soil ecology depth improvement side
Method.
Background technology
Coastal area it is widely distributed various marine solonchaks, this kind of soil lack curing in itself, soil quality is inferior, exists
Salinization of soil and the inferior double combination obstacle of soil quality, the water soluble ion being harmful to crop is excessive, and crop is not easy to emerge, in general
Saline alkali tolerant plant grows and can be all suppressed.
However, this kind of soil has, soil layer is deep, physical features is flat, suitable for advantages such as tractor-ploughing, but due to excessive salinity
Presence, surface soil alkalinity is strong, makes crop yield relatively low or even has no harvest, form the saline-alkali wasteland of large area, ecological environment is severe.With
The increasingly reduction using cultivated land resource, salt-soda soil is as a kind of precious standby soil resource, and it is developed and improvement
By as the important source using soil.
Salt-soda soil can briefly be divided into light salt-soda soil, moderate saline-alkali soil and heavy saline using among process.Slightly
Salt-soda soil refers to its emergence rate 70~80%, and salt content is below 3/1000ths；Refer to its salt content heavy salinizedly
More than 6/1000ths, emergence rate is less than 50%；This middle block is exactly moderate saline-alkali soil.It is expressed as with pH value：Slight alkaline land pH
It is worth for 7.1~8.5, moderate saline-alkali soil pH value is 8.5~9.5, and heavy salinized ground pH value is more than 9.5.
At present, saline and alkali land improvement method mainly has physically improved, water conservancy improvement, biological modification and chemical modifying.Wherein thing
Reason and water conservancy improvement are quick, but cost is too high.Biological modification investment is minimum, but slowly effect.Chemical improvement agent is mostly industry
Byproduct, contain the harmful components such as complex chemical impurity.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of improvement cost is low, quick and ecological, environmental protective moderate salt
Alkali ground soil ecology depth modification method.
In order to solve the above technical problems, the technical scheme is that：Moderate saline-alkali soil soil ecology depth modification method,
Comprise the following steps：
Step 1: remove salt-soda soil region to be improved surface irregularities, weeds；
Step 2: spread fertilizer over the fields compound bio modifying agent to waiting to improve saline and alkaline ground surface, compound bio modifying agent dosage is 20~
50Kg/ mus；Stucco soil, carbide slag and humic acid potassium are mixed while spreading fertilizer over the fields compound bio modifying agent, in a short time amount reproduction soil
Beneficial microbe, quickly activates soil activation, and acceleration forms soil granular；
Ploughed Step 3: treating improvement salt-soda soil within the 48h of implementation steps two, be smooth, being poured water, overlay film, being incubated
Humidification 10~15 days, acid-base balance is nursed one's health while reducing soil salt and alkali content, and make microorganism excessive multiplication death by suffocation, created
Make sterile soil environment；
Step 4: after soil is dried in membrane removal, applying fermentation organic fertilizer, fermentation Rate of Organic Fertilizer is 800~1500Kg/ mus,
Make quickly to breed probiotics formation flora advantage in soil, then sow salt-tolerant plant and biological depth improvement is carried out to soil；
Step 5: when the salt-tolerant plant increment of sowing reaches maximum, salt-tolerant plant is removed, salt-tolerant plant takes away soil
A large amount of salinities in earth, moderate saline-alkali soil soil improvement is completed, subsequently can carry out afforestation management by gardens codes and standards.
