s1: the land is arranged into a plurality of units according to the plane size, and each unit comprises: the system comprises a concrete water-resisting layer laid on soft soil, a water-containing layer laid on the upper surface of the concrete water-resisting layer, a salinized soil layer laid on the upper surface of the water-containing layer, and a salt content detection device, a drainage ditch, an intelligent water storage system and a water supply system which are arranged at the bottom of the salinized soil layer;
s2: supplementing water to the water-containing layer, allowing water to move upwards under capillary action and salt to move upwards, evaporating water after the water reaches the surface layer, and keeping the salt on the surface layer; the salinity continuously moves upwards along with the process, and when the salinity of the bottom soil reaches the salinity of the normal soil, the salinity of the bottom soil is detected by the salinity detection device, the surface soil is removed, and the desalted normal soil is obtained;
s3: before rainfall, the rain-proof cloth is automatically unfolded to prevent rainwater from entering into the desalted soil, so that salt is infiltrated and the desalting process is damaged; simultaneously, the rainwater is collected through the cloth that keeps off the rain to converge into the escape canal, there is a infiltration hole that links to each other with the infiltration layer in the escape canal mesophragma 5m, after the infiltration hole has filled the infiltration layer, continues to flow into the tank, and the inner wall of tank is provided with high level sensor and low level sensor, matches the setting with electric valve again, can carry out intelligent water storage, and the tank water storage is for desalination or desalination completion back, and the plant normally irrigates the use.
2. The method of claim 1, wherein the method comprises the steps of: in the step S1, the concrete water-proof layer is formed by making a water-proof layer on the surface of the concrete layer or laying a layer of water-proof film, wherein the thickness of the concrete layer is 5-10cm, the depth of the concrete layer is set to be more than the highest flood level of a nearby river, and the water-proof layer or the water-proof film is used for preventing the salt of the lower layer of salinized soft soil from moving upwards through capillary action and also can prevent the water from permeating downwards after the salt is removed.
3. The method of claim 2, wherein the method comprises the steps of: in the step S1, the thickness of the aquifer is 20cm, the bottom layer is stones with the diameter of 2-5cm, and the upper layer is sand with the diameter of 0.2-0.5 cm.
4. The method of claim 3, wherein the method comprises the steps of: in the step S1, the saline soil is taken from soil nearby a water storage pool, and the particle size of the saline soil is below 2 cm.
5. The salinity detection device of the coastal salinized soft soil desalination method of any one of claims 1-4, comprising a conductive electrode (25), a first detection electrode (26A), a second detection electrode (26B), a third detection electrode (26C) and a fourth detection electrode (26D).
6. The intelligent water storage system for the coastal salinization soft soil desalination method according to any one of claims 1-4, which comprises a horizontal frame (1), an electric extension structure (2), a shed frame (3), a rain shielding cloth (4), a water storage tank (5) and an intelligent control box (6).
