Abstract

The invention discloses a soil culture medium suitable for growth of a plant on a metallurgy tailings dam and the preparation method of the soil culture medium. The soil culture medium consists of a component A and a component B, wherein the component A is clean water, and the component B is prepared by compounding the following components by weight percent: 30%-38% of clay, 18%-25% of montmorillonite, 36%-40% of organic substances, 3% of slow release fertilizer, 1%-3% of stabilizer, 0.35%-0.85% of granulation agent and 0.5%-3% of plant seeds. The soil culture medium provided by the invention is great in porosity and good in water and fertilizer conservation, can complex heavy-metal ions, reduces the salinity and alkalinity of the soil, increases the content of the organic substances in the soil, provides various nutrients required by the growth of the plant, can solve the problems of poor vegetational type stability, insufficient soil replacement raw materials, over-high cost and the like in the biological reparation of the existing tailings pond, and has good environment benefit and social benefit.

Description

technical field [0001] The invention relates to a preparation method of a plant growth soil medium, in particular to a plant growth soil medium specially used for metallurgical tailings dams and a preparation method thereof. Background technique [0002] Metal mines discharge a large amount of tailings after ore sorting, and then build dams and storehouses to store tailings to form a tailings pool. The tailings stockpiling area lacks vegetation and the stability of the matrix is ​​poor. When it rains, the tailings slag will be lost with the rainwater, resulting in deterioration of the water body; drought It spreads with the wind from time to time, leading to air pollution and barren soil in surrounding areas, causing serious harm to the ecological environment, and sometimes even directly threatening the survival of humans and animals. Therefore, the treatment of tailings pollution is imperative. Due to the invasion and pollution of tailings sand for many years, the dam body ...
