Abstract

The invention provides a long-acting regreening method for quarrying exposed mountains. The long-acting regreening method for quarrying exposed mountains comprises the following steps: (1) digging an inclined square hole in a mountain; (2) flatly laying an efficient water-retaining agent on the lower part of the square hole; (3) placing a groined plastic efficient water-retaining channel support in the square hole, and enabling a groined surface to the inner side and the outer side of the square hole to form a water-retaining channel; (4) filling the water-retaining channel with nutritional soil; (5) covering the surface of the nutritional soil with planting concrete, and reserving through holes as planting holes; (6) mounting a rainwater receiver at the edge of the lower part of the square hole, enabling the lower edge of the rainwater receiver and the lower edge of the square hole to be on the same horizontal line, communicating the rainwater receiver to the inside of the planting concrete, and enabling the tail end of the inner side of the rainwater receiver to communicate with the efficient water-retaining agent; and (7) cultivating plants. The long-acting regreening method is a local ecological establishing method in which the process is simple, and raw materials are easily obtained, water and soil loss can be prevented, evaporation of the surface of soil is reduced, the survival rate of the plants is increased, and long-term, effective and continuous ecological balance can be guaranteed by natural rainfall.

Description

technical field [0001] The invention relates to a long-acting regreening method for exposed 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 most important reason for the lack of plant growth on barren slopes is the lack of suitable substrates for plant growth. The growth of plants must depend on the gr...
