Embodiment

[0044] The embodiment of the present application provides a rapid repair system for saline soil sites. The system comprehensively adopts a repair method combining directional salt discharge and physical and chemical improvement, and can repair saline soil sites economically, effectively and quickly. A specific form of a rapid repair system for saline soil sites will be described in detail below in conjunction with the accompanying drawings.

[0045] Such as figure 1 As shown, in the embodiment of the present application, the rapid repair system for saline soil sites is the first saline soil layer 1, straw landfill layer 2, second saline soil layer 3 and improvement agent improvement from bottom to top. Layer 4.

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

[0047] The upper surface of the first saline soil layer 1 is a straw landfill layer 2, and the thickness of the s...

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.

Description

technical field [0001] The present application relates to the technical field of improvement and utilization of saline soil, in particular, to a rapid restoration system and method for saline soil sites. Background technique [0002] The problem of soil salinization exists widely in the world and has become an important factor restricting the sustainable development of modern agriculture. The area of ​​saline soil in my country ranks among the top in the world, mainly distributed in Xinjiang, Inner Mongolia, Qinghai, Gansu, Ningxia and other regions. The area of ​​saline soil in my country is about 36.933 million hm 2 , about 44.867 million hm of residual salinized soil 2 , the potential salinization soil is 17.333 million hm 2 , a total of 99.133 million hm 2 , of which the area of ​​salinized cultivated land is nearly 6.7 million hm 2 , accounting for about 5% of the country's total cultivated land (see Yang Jinsong. The development history and prospect of saline soil ...
