Method for repairing sulfur-polluted soil by using tamarix plants

The invention relates to a phytoremediation technology for environmental pollution, in particular to a method for remediating sulfur-polluted soil by using tamarix plants, which comprises the following steps: collecting tamarix chinensis seeds; collecting tamarix chinensis branches; a buffer area is arranged in the sulfur-containing polluted soil, the buffer area is divided into a plurality of sowing areas and transplanting areas, and the sowing areas and the transplanting areas are independently arranged and/or arranged in a crossed mode and used for repairing the sulfur-containing polluted soil in different repairing periods. Tamarix chinensis seeds are sown in each sowing area, and tamarix chinensis cutting slips are cut in each transplanting area; carrying out irrigation management on the tamarix chinensis seeds and/or cutting slips collected in the buffer area, so that sulfur in the polluted soil is absorbed through tamarix chinensis root systems and is transferred to the overground part; and after the t
