Tailing pond soil conditioner and application method thereof

Abstract

The invention discloses a tailing pond soil conditioner and an application method thereof. By weight part, the tailing pond soil conditioner comprises: 30-40 parts of slow release fertilizer, 20-30 parts of turfy soil, 20-30 parts of medical stone, 15-20 parts of kieselguhr and 5-10 parts of water-retaining agents. The tailing pond soil conditioner and the application method thereof solve the problems that reclamation rate of tailing ponds is low due to the fact that the reclamation rate of the tailing ponds is limited by factors of poor structures, nutrient loss, heavy metal toxicity and the like of matrixes, not only solve secondary damage caused by a soil dressing method, but also improve utilization rate of fertilizer, and simultaneously achieve fixing effect for heavy metal in tailing pond soil, reduce toxicity of the matrixes, improve emergence rate of seeds, reduce harm to plant growth, and effectively reduce pollution of tailings to surroundings.

Description

Technical field

[0001] The invention belongs to the field of tailing pond soil improvement, and specifically relates to a tailing pond soil amendment and an application method thereof. Background technique

[0002] With the development of the economy, the demand for mineral products has increased significantly, and the scale of mining resources has increased accordingly. Therefore, the number of tailings ponds produced has been increasing. The exposed tailings can easily cause collapse and landslides during the rainy season, and dust in the windy season. In particular, tailings containing heavy metals can cause serious pollution to the surrounding water bodies, soil, animals and plants, thereby affecting human health. The reclamation of the tailings pond can restore the land use function of the mining area, protect the cultivated land, restore the ecological environment, and play an important role in the management of the ecological environment of the mine. Due to the poor soil ...

Examples

Embodiment 1

[0042] By 350g / m 2 Sowing a soil conditioner, which includes the following raw materials in parts by weight: 35 parts of slow-release fertilizer, 23 parts of turf soil, 22 parts of medical stone, 15 parts of diatomaceous earth, and 5 parts of water-retaining agent. Use agricultural machinery to plow to 40cm, irrigate to saturation, and allow the modifier to fully ferment in the tailings for 5 days; press 20g / m 2 Sow winter thatch seeds, then cover with non-woven fabrics, and water them appropriately according to the weather conditions after 5 days of curing, and observe the growth.

[0043] The grass seeds germinate 5 days after sowing, and the germination rate is more than 70%. After 10 days, they grow into seedlings. After 50 days, the first grass matures and the grass seeds fall off to enter the second generation of reproduction. After 3-4 months, the vegetation is fully covered, and the perennial plants can reproduce naturally.

Embodiment 2

[0045] The amount of slow-release fertilizer is preferably 35 parts.

[0046] The amount of peat soil is preferably 30 parts.

[0047] The amount of medical stone is preferably 25 parts.

[0048] The amount of diatomaceous earth is preferably 18 parts.

[0049] The amount of water retaining agent is preferably 8 parts.
