Description
Technical field
The present invention relates to geology transformation field is and in particular to a kind of modification method in salt-soda soil.
Background technology
Salt-soda soil refers to that in soil, (particularly upper soll layer 0-20cm) is solvable containing substantial amounts of sodium chloride and sodium carbonate etc.
Property salt, have a strong impact on as growth, salt-soda soil typically drought short of rain, evaporation capacity is big, the low flat, level of ground water of physical features
Formed under the natural conditions such as high, salinity is big and Mankind action, the inland saline-alkali soil of China is mainly distributed on northeast, China
The ground such as north, northwest, although some areas are to build Garden Greenland in good farmland ground, are irrigated with underground salt water, will also result in
Soil Secondary salt-soda soil.The most intuitively performance is soil compaction to saline-alkali soil and Soil structure is poor, and after irrigation, grogs is easy to certainly
Move and disperse and form skinning, and then stop moisture from penetrating into and reduce soil water storage capacity.Saline land greening engineering is due to by soil
The restriction of the local conditions such as earth, weather, construction and late maintaining difficulty are very big, and improving flower plants and nursery stock survival rate is the task of top priority,
How to realize quickly improving, long-term maintenance is that we need to make an effort to be improved.
Content of the invention
Problem to be solved by this invention is to provide a kind of modification method in new salt-soda soil.
To achieve these goals, the technical scheme that the present invention takes is:A kind of modification method in salt-soda soil, including as follows
Step:
(1)Phosphogypsum powder is uniformly applied in soil surface;With rotary cultivator, fertilizer and surface are carried out rotary tillage, spread fertilizer over the fields ardealite
The soil of powder is poured water, and soaks 1-3d;The solution of sodium ion adsorbent configuration is uniformly sprayed application on water layer, and continues to soak 1-
2d;Water in salt-soda soil is drained;
(2)After applying azophoska in the soil of top layer 5-10cm, carry out turning over kind, expose lower soil, in lower soil
After adding attapulgite, waste mushroom leftover, humic acid, bagasse, composite bacteria agent capable to carry out rotary tillage mixing, spread last layer in soil surface
Breeze soil, then restore topsoil;
(3)In step(2)Subregion plantation, interval plantation green plants and conventional plant, every batch of plant are carried out on the soil obtaining
After plantation, change the planting location of green plants and conventional plant.Preferably, step(1)Water layer thickness above middle soil is
3-10cm, described method that water in salt-soda soil is drained is that the lower in salt-soda soil digs trenches to drain the water away.
Preferably, step(1)In sodium ion adsorbent be cationic-type polyacrylamide.
Preferably, step(2)The preferred Caulis et Folium Oryzae of middle waste mushroom leftover, straw or corn cob fiber material culture Pleurotus ostreatus, Pleurotus sajor-caju
The mushroom bran obtaining afterwards.
Preferably, step(2)Comprise nitrogen-fixing bacteria, salt tolerant root nodule bacteria, Salt And Alkali Tolerance phosphate solubilizing bacteria in middle composite bacteria agent capable and bite saline and alkaline
Two or more in bacterium.
Preferably, step(1)The consumption of middle phosphogypsum powder is 300-1000kg/ mu, and the depth of rotary tillage is 15-30cm.
Preferably, step(3)In green plants select Dallis grass, the Planting Years of described green plants are 3-5.
Preferably, described Dallis grass plantation position is from kind of a stem.
The beneficial effects of the present invention is, it is possible to achieve quick plantation demand plant and the double-deck effect improving soil for a long time
Really, it is mostly because level of ground water is high using salt-soda soil, under shining upon, the evaporation upwards of water not section, causes substantial amounts of salt to stay
The Crack cause causing in the earth formation, quickly improves the property of soil using salt discharge method, reduces soil pH, reduces the salt in soil
Class material, increases permeability and the preservation capacity of water and fertility of soil, passes through attapulgite and the fluffy soil of bagasse to lower soil, give up
Abandon mushroom bran, humic acid and composite bacteria agent capable to realize chronic digestion salinity, realize the improvement of long-term salt affected soil, reduce salinity
Accumulation once again, the use of breeze soil can separate salinity and rise, and increase the survival rate of first time planting plants and rate of growth,
The suction salt ability of green plants is strong, and root system is deep, can fully take away in the salinity in soil, fundamentally solve in growth course
The high problem of salinity in soil layer.
