Embodiment 1

[0026] Abandoned Mine Dump Site Vegetation Restoration Pilot Experimental Restoration Pilot Site Selection: Gongchangling Iron Mine Dump Site, the abandoned ore soil is immature soil, mainly stones and gravel. Planting time: April 2017.

[0027] The plant restoration method of the mine dump specifically includes the following steps:

[0028] (1) Cleaning: In the early stage of construction, firstly, the construction area shall be cleaned and repaired, and the sundries and rocks on the dump site platform to be restored shall be removed to increase the greening effect.

[0029] (2) Digging pits: Use a multi-purpose tree planting pit digging machine to dig 150 pits on the dump site to be restored after cleaning. The pits are circular and have a volume of about 0.0524m 3 , the diameter of the upper part of the pit is about 0.4m, and the depth of the pit is about 0.4m; the distance between adjacent pits in each row is 0.3m, and the row spacing is 0.5m.

[0030] (3) Preparation of...

Abstract

The invention discloses a plant recovery method for a waste disposal site of a mine. The method comprises the following steps that foreign materials in the waste disposal site are cleaned; pits are dug in the waste disposal site to be recovered; after that soil in the area to be recovered passes a 40mm soil sieve, the soil, lake deposit, an organic fertilizer, a water-retaining agent and rice husks are mixed to prepare a soil matrix; saplings, in the height about 30cm, of Rhus typhina and Fructus Hippophae are planted in the pits; and watering and maintenance are implemented. The method is simple, the vegetation survival rate is more than 95%, the application amount of alien earth is reduced, the cost is reduced, better ecologic recovery and landscape effects are achieved, and the method is suitable for application and utilization in large area.

Description

technical field [0001] The invention belongs to the field of ecological restoration, and in particular relates to a method for restoring plants in mine dumps. Background technique [0002] Dump (dump, wastedump, wastepile), also known as waste rock field, refers to the place where mining waste is discharged intensively. The dump site is one of the abandoned mine sites. The soil quality is poor, the nutrition is deficient, and the water and soil loss is serious. The dump site not only occupies a large amount of land, but also brings serious pollution and harm to human production and life. It has been recognized by the whole society The increasing amount of dumps has aggravated the occurrence of regional soil erosion and has become an important source of new soil erosion, and its consumption has always plagued the development of cities and the progress of society. Dumps not only cause public nuisance, but also a huge waste of resources. Therefore, how to solve the resource u...
