Method for ecological restoration of abandoned mine and ecological greening in mining area by using hybrid paper mulberry and application thereof

Abstract

The invention discloses a method for ecological restoration of abandoned mine and ecological greening in a mining area by using hybrid paper mulberry and application thereof. The method uses the original soil cultivation and achieves the standardization from the choice of planting land, seedling preparation, water and fertilizer management, pest control and other aspects, and is matched with simple management measures, which ensures the survival and growth of hybrid paper mulberry and establishes an ecological greening system of hybrid paper mulberry in mining area. The experiment proves that the method for ecological restoration of abandoned mine and ecological greening in mining area can achieve the original soil cultivation and survival of hybrid paper mulberry, and the good adaptability can be shown under the circumstance that too many engineering measures are not taken to the abandoned mines. The cost of ecological remediation and landscape engineering is greatly reduced, which enriches tree species resources applied to the abandoned mine greening. The method for ecological restoration of abandoned mine and ecological greening in the mining area by using hybrid paper mulberry has the wide application prospect in the ecological greening of abandoned mines.

Description

technical field [0001] The invention belongs to the field of ecological environment management and restoration, and in particular relates to a method for ecological restoration of abandoned mines and ecological greening of mining areas by using hybrid mulberry tree and its application. Background technique [0002] Mineral resources are an important pillar of my country's social and economic development. However, the development of mineral resources is also the largest organized human activity to change the earth's surface landscape and destroy the surface ecosystem. Due to the long-term disorderly mining and the predatory development method that emphasizes profits and neglects protection, many environmental problems have been caused, such as the destruction of surface vegetation. During the mining of mineral resources, especially open-pit mining, there is no vegetation on the surface. Dust storms are generated under the influence of precipitation, which may cause soil erosi...

Problems solved by technology

Due to the long-term disorderly mining and the predatory development method that emphasizes profits and neglects protection, many environmental problems have been caused, such as the destruction of surface vegetation. During the mining of mineral resources, especially open-pit mining, there is no vegetation on the surface. Dust storms are generated under the influence of precipitation, which may cause soil erosion and even landslides; heavy metals in the mining, washing and smelting process pollute the soil, nearby rivers and groundwater, seriously affecting the yield and quality of surrounding farmland crops, and posing potential hazards to human health. threaten
