Problems solved by technology
The physical method is mainly based on leaching and salt discharge, combined with plowing, leaching, silting and other measures to achieve the purpose of improving saline-alkaline soil; the chemical method is to reduce the saline-alkaline soil by adding some acidic chemicals and organic polymer materials, combined with organic fertilizers. The degree of soil salinization, but both methods have problems such as high cost, easy to cause secondary pollution of soil and surrounding water sources, and it is not easy to reduce the soil salinity content

Embodiment 1
[0049] see Figure 1-4 and Figure 6-7 , a pre-embedded double-effect restoration method based on saline-alkali land, comprising the following steps:
[0050] S1. When the saline-alkali land returns to salt season, set up multiple groups of film-covered diversion chambers 101 corresponding to the vertical direction on the saline-alkali soil layer 1, and set up one and multiple film-covered diversion chambers on the saline-alkali soil layer 1. One end of the cavity 101 is connected to the thermal storage crystallization cavity 102, and on the saline-alkali soil layer 1, the end away from the thermal storage crystallization cavity 102 is embedded with a plurality of pre-buried perfusion pipes 2 inserted in the film-covered diversion cavity 101. The perfusion tube 2 is provided with irrigation holes;
[0051] S2. Pre-embed and install a crystallization box 3 with a heat conductor inside the heat storage crystallization chamber 102. A water-conducting layer 4 is embedded at the ...

The invention discloses a pre-embedded double-effect restoration method based on saline-alkali land, which belongs to the technical field of saline-alkali land restoration. By setting up interconnected film-covered diversion chambers and heat storage crystallization chambers inside the saline-alkali soil layer, multiple pre-embedded The perfusion pipe pours into the saline-alkali soil layer, and the water is drained to the thermal storage crystallization chamber through multiple film-covered diversion chambers, which plays a large-area horizontal leaching effect on the saline-alkali soil layer soil, and the water with salt is draining Under the action, it is adsorbed by the water-conducting layer. Due to the cooperation of the light-absorbing heat-storage layer and the heat conductor in the crystallization box, the temperature inside the crystallization box rises. On the crystalline surface layer of high temperature, it can fully realize the large-scale leaching and precipitation of the salt on the surface of the soil and below it. The application efficiency is high, the repair time is short, and it can effectively remove the salt while also playing a very important role. Good moisturizing effect, play a double-effect repairing effect.
Description
technical field [0001] The invention relates to the technical field of saline-alkali land restoration, more specifically, to a pre-embedded double-effect restoration method based on saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. Most of the saline-alkali land is related to the accumulation of carbonate in the soil, so the degree of alkalinity is generally high, and severe salt Plants in alkaline soil areas can hardly survive. All kinds of saline-alkali soils are formed under certain natural conditions. The soil surface layer gradually builds up in salt-collecting areas. The accumulation of salinity in soil is the result of the superposition of a series of natural and human factors acting on different temporal and spatial scales. Soil salinization seriously restricts agricultural development, improving and restoring large areas of saline-...
