soil improvement, specifically related to a saline-alkali soil desalination
agent and its preparation method and use method thereof.
Background technology Saline-alkali land is a kind of salt accumulation, which refers to the
salt in the soil that affects the normal growth of crops, leading to the
low vegetation capping rate of saline-alkali land. The reason for the
formation of saline-alkali land is the high content of underground salt,
which is penetrated upward through the soil capillary. Due to less
precipitation, the salt infiltrated above the soil can not be discharged
quickly and gradually accumulates on the surface.
At present, the main measures for saline-alkali land treatment are:
salt washing, Fill the water into the saline-alkali fields, Fully dissolve
the salt in the soil, And it shall be discharged through the drainage ditch;
Flat the land, After ploughing, Salt in the surface soil can be buckled to
the lower layer, Turn the lower less salt soil to the surface; Timely rake
rake, Looloose topsoil, Cut off the soil capillary water to deliver salt to
the surface, Prevent the role of salt return; Increase the organic
fertilizer, Salt-alkali land is generally characterized by low temperature,
thin soil and poor structure, Organic fertilizer is decomposed and
transformed by microorganisms to form a humus, Improve the soil, And can
act with sodium carbonate to form sodium humus, Lower soil alkaline.
The above methods are complicated, time-consuming and ineffective, so
how to improve the saline-alkali land easily and efficiently needs further
research.

Example 1 0.19 7.2 380
Example 2 0.22 7.5 368
Example 3 0.2 7.3 372
PScale 1 0.41 9.5 150
Pratio 2 0.21 7.9 316
From the results of Table 1, In contrast to proportional 1, Example i3
reduces the soil soluble salt amount after using the desalination agent and
the desalination method, Down by up to 53.65%, The pH is reduced to 7.27.5,
Near-neutral, While cotton yield increased by 153%, This shows that the
desalination agent and the desalination method of the present invention can
effectively reduce the salt content, Adjust the soil pH value, Increase the
crop production; Also, Compared to proportional 1, Scale 2 simply mixing
the desalination agent with the ploughed soil, Its soil soluble salt volume
and pH are also reduced, It shows that the various components of the
desalination agent formula can effectively improve the saline-alkali land;
In contrast to proportional 2, Embodiment l'3 uses both the
demineralization agent of the present invention, Also used in accordance
with the desalination agent method of the present invention, Salt
desalination works better, To ating the method of the desalination agent as
a supplementary means, Can assist the desalting agent to better improve the
desalination effect, As shown in Figure 1, By plowing the soil, First make
the soil rich in desalagent, Open the drain 2 in the ploughed soil, Helps
the discharge of salt in the soil through drain 2, And can provide channels
for the outward discharge of the underground salt (in all directions as shown in FIG. 1A), Reducing the penetration of the underground salt to the soil surface, Excavate planting groove 3, Demineralization agent is applied in the planting tank 3, Further targeted improvement of the soil around the crop roots, Improve the crop survival rate and yield.
In conclusion, the components of the desalination agent can cooperate
with each other to effectively remove salt, improve the soil crop yield of
saline-alkali land, and use waste as raw materials with low cost and green
environmental protection. Improve the soil with simple method, good effect
and suitable for large-scale promotion.
Obviously, those skilled in the art may make various changes and
variations of the invention without departing from the spirit and scope of
the invention. Thus, if these modifications and variations of the present
invention are within the scope of the present invention and its equivalent
technology, it is also intended to include these modifications and
variations.
