The main salt-draining pipes are alternately distributed with constriction parts and diffusion parts at equal intervals, and both ends of the secondary salt-draining pipes are respectively connected to the constriction parts of two adjacent main salt-draining pipes, so that the main salt-draining pipes and the secondary salt-draining pipes form a square network structure, and the adjacent main salt-draining pipes are connected through the micro-power generation device; in the present invention, the main salt-draining pipes and the secondary salt-draining pipes are used to collect the salt in the soil and discharge it into the open ditch or artificial well to achieve soil desalination and improve the soil environment. On the other hand, the flow of water drives the micro-generator through the power blades to generate electricity, electrolyze the brackish water, and use the electrolysis effect to collect the metal cations and salts in the brackish water, reduce the salt content in the brackish water, and gradually improve the soil environment.
