Abstract

The invention provides a greening method for a quarrying bare mountain massif. The method includes the following steps that 1, oblique square holes are dug in the mountain massif; 2, water retention channels are filled with nutrient mediums; 3, prefabricated plant-growing concrete blocks are adopted to cover the nutrient mediums; 4, four sides of each square hole are sealed and reinforced with cement slurry; 5, propagation materials of plants are planted in planting holes, and a small amount of water is poured. According to the problem that the survival rate of the plants is low and water is not easy to obtain in the artificial greening process of the quarrying mountain massif, the long-acting greening method of the bare mountain massif is provided; according to the long-acting greening method, raw materials are easy to obtain, the cost is low, the process is simple, and it is ensured that ecological balance can be effectively maintained for a long term.

Description

technical field [0001] The invention relates to a method for regreening bare mountain bodies, and belongs to the field of environmental ecological restoration. Background technique [0002] Since the reform and opening up, with the continuous development of the economy, mountain quarrying has become one of the important links in infrastructure construction. Mountain quarrying not only leads to fragmentation of vegetation, destruction of natural landscape and sharp decline of biodiversity, but also creates bare wasteland after mining, deteriorating the ecological environment. At present, bionic plastic nets are mostly used for direct coverage. Although they have a certain beautification effect, they do not help the environment. Moreover, the plastic nets are aging and cause secondary pollution. The abandoned Shishan mining area has no soil, or the soil layer is thin and extremely barren, with poor water and soil retention capacity, serious soil erosion and rocky desertificat...
