Problems solved by technology

[0002] There are many types of soil improvers: minerals, mainly peat, lignite, weathered coal, lime, gypsum, vermiculite, bentonite, zeolite, perlite and sepiolite, etc.; natural and semi-synthetic water-soluble polymers, mainly Straw, polysaccharide materials, cellulose materials, lignin materials and resin glue materials; synthetic polymer compounds, mainly polyacrylic acid, vinyl acetate maleic acid and polyvinyl alcohol; beneficial microbial preparations, etc. In recent years, with the continuous and rapid development of my country's urbanization process, the number of urban population has continued to increase, and at the same time the output of heavy industrial sludge has continued to increase. become smaller, the number is reduced, and the antibacterial, cold resistance, and drought resistance of crops are weakened. Therefore, it is urgent to develop a soil conditioner that can handle heavy metals in soil, improve soil quality, and improve crop quality.
[0003] Most of the existing soil improvers are for improving soil quality and lack the effect of treating heavy metal ions in soil. The Chinese patent document (publication number: CN105777424B) discloses an acidic soil improver made from iron ore tailings. The acidic soil improver contains The
