Example Embodiment

[0043] Example

[0044] The present application example provides a rapid repair system for saline soil field, which combines a repair method of directional salting and physical chemical improvement, which can be repaired economically, effective and rapidly. A specific form of a rapid repair system for a saline soil site is described in detail below with reference to the accompanying drawings.

[0045] Such as figure 1 As shown, in the present application, the rapid repair system for saline soil is sequentially sequentially sequentially the first saline soil layer 1, straw landfill layer 2, the second saline soil layer 3 and the modified agent improvement Layer 4.

[0046] The first saline soil layer 1 is a deep saline soil in the field, specifically greater than the saline soil at 0.8m below the surface.

[0047] The first saline soil layer 1 is a straw landfill layer 2, and the thickness of the straw landfill layer 2 is 5 cm to 10 cm. The straw landfill layer 2 can form a "separator

Abstract

The invention provides a rapid restoration system and method for a salinized soil site, and belongs to the technical field of salinized soil improvement and utilization. The rapid restoration system sequentially comprises a first salinized soil layer, a straw landfill layer, a second salinized soil layer and a modifier improvement layer from bottom to top. Meanwhile, the system further comprises a site water flow salt discharging system, and the site water flow salt discharging system comprises a first water collecting pond, a main channel, a branch channel, a second water collecting pond, a first salt settling pond, a second salt settling pond, a salt discharging water recycling main canal and a semi-permeable membrane. According to the rapid restoration system, the restoration method combining directional salt discharging and physical and chemical improvement is comprehensively adopted, a directional channel for water and salt migration is formed through straw landfill and site salt discharging, and salt in a site is discharged; and through physical and chemical improvement, the salt content of the earth surface is reduced. The salinized soil site can be restored and improved economically, effectively and quickly, and technical support is provided for quick restoration of the salinized soil.
