Study On The Screening And Construction Technology Of Green Plants In Baoding Mining Area

As the economy develops, the state rapidly increasing demand for mineral resources, mining caused massive land mines and vegetation destruction. The mining of mineral resources is a great contribution to the economic development of our country at the same time, also causes a series of environmental problems. Ecological restoration of mining area has become an important part of ecological environment construction in our country, through the ecological restoration of mine, can effectively improve the ecological environment, but the mine’s natural vegetation recovery is very slow, shall actively adopt related artificial measures to speed up the process of planting vegetation, make it at the same time, the ecological benefit and can win economic benefits.In this paper, the city limestone mines and Lai source mountain city iron ore alone natural geographical environment, different site conditions on the field survey, through the method of screening of pioneer plant layout samples, in the city limestone mining area, a total of 37 species, belonging to 18 families, 33 genera, Lai source iron ore mining area, a total of 53 species, belonging to 24 families, 46 genera, the city in compositae, gramineae, ricinus communis and leguminous plants, most salsola, thorns, spear leaf hispid arthraxon as mining area advantage plant; Lai source in compositae, gramineae, leguminosae and euphorbiaceae plants, most small red chrysanthemum, die-hard artemisia, white lotus plant artemisia, dog’s tail grass for advantage.In Boston ivy and leaves for selected plants, with Chinese wolfberry in different concentration of cutting rooting agent under the condition of experiment, the suitable concentration of two kinds of plant cuttings rooting abt is 200 mg/L; Soil, tailings, lignite, water retention agent as matrix materials, with Chinese wolfberry leaves as the selected plant, through the orthogonal experiment method, ratio analysis of 9 kinds of different substrates on leaf with medlar growth situation, the influence of filter is suitable for plant growth and development, the optimal ratio of substrate to substrate, 60 g dried soil, 8 g water retention agent, 1.0 g of 1:1 ratio of fertilizer and quality tailings and lignite, through mining slope ecological bag beautification stacking method, realize mine ecological recovery; According to different varieties of Boston ivy climbing ability and growth rate, the difference of the sino-us Boston ivy grafting experiment was carried out, and finally obtain the growth speed, strong climbing new Boston ivy, in order to grow in front of the wall in the future.Through the Mancheng limestone mines and Laiyuan iron ore mines vegetation recovery technology for in-depth study, different site conditions of vegetation recovery mode, corresponding technical measures are put forward, further improve the ecological environment in mining areas, conservation of ecological restoration of mining investment cost to ensure the ecological restoration of long-term benefits, accelerate the similar mine geological environment governance, for mines vegetation restoration technology to provide theoretical and technical support.
