Embodiment Construction

[0025] The present invention is further explained below in conjunction with the examples, but the examples do not limit the present invention in any form.

[0026] Ramie was planted at a distance of 1m, and the seedlings of tolerant herbaceous plants Miscanthus chinensis, Luzhu and coreopsis were transplanted in the field, cultivated at 0.5m intervals, and 20cm of abandoned farmland soil surface was collected to cover the soil surface to be repaired, with a thickness of 5cm. Select tolerant herbaceous plant bermudagrass, tall fescue, horseshoe gold, bluegrass, ryegrass, white clover, brome, green foxtail, small fly canopy and alfalfa seeds to mix and sow in the overburden layer by the sowing rate of 2kg per mu; Collect moss crusts in an area of ​​2 mu, mix them with soil and decomposed organic fertilizer, spread them on the surface of 10 mu of soil to be repaired, and then cover them tightly with straw; before the rain comes, apply 10kg of inorganic fertilizer per mu for 5 time...

Abstract

The invention discloses a method for jointly repairing vegetation and application thereof. The method comprises the steps of: (1) planting shrubs; (2) covering soil, and sowing seedlings of resistant herbaceous plants or planting seedlings of herbaceous plants; and (3) sowing moss. The method has low cost and remarkable effect, can avoid or control the pollution of heavy metal, can avoid and fix sands or conserve water and soil, and plays an important part in protecting environment.

Description

technical field [0001] The invention relates to the field of soil protection, in particular to a vegetation joint restoration method and its application. Background technique [0002] Tailings are a large amount of gangue waste that is discharged after the ore is selected as concentrate. According to the China Environmental Yearbook, tailings are the industrial solid waste with the highest discharge in my country, accounting for nearly 30% of the total industrial solid waste discharge. Due to the extremely high content of heavy metals (such as Pb, Zn, Cu, Cd, As, Ni, etc.), tailings have brought serious heavy metal pollution to surrounding land and farmland through soil erosion and wind seeding, and their environmental impact is universal. , severity, persistence, and locality. my country's tailings cover an area of ​​more than 900,000 hectares, but the reclamation rate is only 5%. The pollution of tailings continues to worsen, especially the soil pollution in major heavy m...
