Drought-resisting afforesting and grass growing method for mining area

Abstract

The invention discloses a drought-resisting afforesting and grass growing method for a mining area. Firstly, local tree seeds suitable to be planted in the local mining area are selected, and manual watering afforestation is performed on degenerated land in the spring seeding season with a traditional technology; then the land surface is raked to be flat with a manual land preparation method, and local grass seeds suitable to be planted locally are selected and scattered onto the land surface manually; finally, the land surface after seeding is covered with pollution-free slag and rubble which are discarded in the mining area during mining to finish slag-covering afforestation and grass growing. Due to the rubble and the slag covering the land surface, the land surface roughness is increased, the land surface wind speed is decreased, the implantation and sprout probability of the plant seeds is guaranteed, meanwhile, land surface water evaporation can be prevented, growth and development of the trees and grass are promoted, the discarded rubber and slag can be changed into wealth, the ecological environment of the mining area is improved, and the environmental pollution is reduced. The method is particularly applicable to ecological restoration and environmental protection in arid and semi-arid desertification mining areas.

Description

technical field [0001] The invention relates to a method for planting trees and grass, in particular to a drought-resistant afforestation and grass planting method suitable for afforestation in arid and semi-arid desertified mining areas, and belongs to the field of plant cultivation. Background technique [0002] my country is a country with severe desertification and a serious shortage of water resources. At the same time, it is also a country with rich mineral resources and active mining. Among them, a large number of abandoned mining areas and slag stacking areas formed during mineral excavation not only occupy limited land resources, but also cause pollution, soil erosion, mudslides and other environmental disasters due to random stacking, which has been criticized in modern society. [0003] In recent years, a series of studies have been carried out in the field of mining environmental protection around the treatment of slag and other wastes, including artificial landf...

Problems solved by technology

However, these studies treat the waste during mine development as a harmful substance, and lack the concept and technology of turning harm into profit and turning waste into wealth, which affects the effective utilization of slag and gravel, and cannot fundamentally solve the problem of waste.
