The Study On The Pot Experiment Of Ore Field Of Bare Slope Wasteland Sowing Greening Substrate

With the large-scale construction of the country’s infrastructure,a large number of containing iron ore resource-rich mountain resources to be mined and destroyed the original habitat, the formation of a huge number of vegetation cover exposed slope.Bare slope formed on the landscape ecological environment caused great damage, leading to soil erosion, severe cases may cause landslides, collapse.The bare side slope ecological restoration has become imminent problems.The study area is located in FanShi city, Shanxi Province, background in iron ore mining area of mining abandoned land.Due to long-term exploration, has formed a large number of bare slope area.Due to the detachment of soil accumulation, form a gentle slope zone.Topographic relief is larger.Slope of soil parent material exposure.The soil phosphorus is higher, low nitrogen.Vegetation coverage is low, and soil erosion is serious.The phenomenon of soil and water loss is serious.In this paper, the soil water retention agent, quick-acting fertilizer and farmyard manure as raw materials of spray seeding matrix, using L9(34) orthogonal table ratio in order to promote the best growth status of Medicago sativa L and Amorpha fruticosa, for the future of mining wasteland by gushing greening substrate technology for vegetation restoration of ecological restoration to provide theoretical support.
