Description
Technical Field
The invention belongs to the technical field of plant cultivation, and particularly relates to a plant cultivation device for ecological restoration of a tailing pond in an arid region and a using method of the plant cultivation device.
Background
The development of mineral resources has problems of environmental pollution and natural disasters while supplying raw materials and supporting economy. The heavy metal content in the abandoned land of the mining area is high, and the toxic heavy metal has concealment and long-term property in the soil system pollution process, pollutes the atmospheric water body, harms the human health, and destroys the ecological balance and biological diversity of the local land. Therefore, the development of ecological restoration in mining areas is an important measure for responding to the environment protection concept of 'silver mountain in Jinshan mountain and Qingshan in Green Water' in China and promoting modern ecological civilization.
At present, the vegetation reclamation technology is an important mode for ecological restoration of a mining area, on one hand, the root system of a plant can absorb heavy metal ions, and the plant body can enrich pollutants; on the other hand, the plant root exudates can improve the soil structure and adjust the soil hydrothermal condition beneficial to plant growth. Vegetation reclamation generally selects a combination of herbs and shrubs or grass pots. Herbaceous plants are small in size and underdeveloped in root system, and the remediation effect on deeply polluted soil is poor; in contrast, shrub individuals are large, the longitudinal penetrating power of root systems is strong, and the remediation effect on soil deep pollution is good.
Mine resources in arid regions are abundant, the mine resources are mostly distributed in deserts or desert regions, natural environment conditions are special (high-temperature drought, frequent sand storm activity, high soil salinization degree and single vegetation type), natural vegetation is abundant in short-lived (halophyte) herbaceous plants, desert shrubs are sporadically visible, and the fragmentation property of a vegetation community system is strong. Therefore, the artificial planting of desert shrubs and the construction of grass-shrub integrated vegetation communities are beneficial to improving the stability of the vegetation community system and promoting the pollution remediation effect of the mining area.
Due to the complex geological structure and poor physical structure of the abandoned mine land, open-cast mining causes the damage of original vegetation and a soil foundation layer on which the vegetation depends to survive, and a large number of rock slopes and mining surfaces are formed. How to reclaim vegetation on a hard rock base surface and establish a vegetation growth foundation becomes a key point for vegetation restoration in a tailing area.
When the existing tree planting machine or pit digging machine is used, a user holds the supporting frame to place the drill rod at the bottom of the gasoline engine on the designated ground, the gasoline engine works to drive the drill rod to rotate, a planting hole is formed in the ground, and the saplings are placed in the planting hole, buried in soil and planted. However, when a rock with a certain hardness or a complex geological structure exists underground in the drilling operation of the existing special tree-planting drilling machine, the drill rod cannot normally rotate in the structure due to excessive resistance, so that the drill rod cannot be drilled, and further, a gasoline engine of the whole equipment is overloaded, and finally, the equipment is damaged. Especially in the arid area in the north, abandoned ores in the open tailing area are accumulated, small individual ores are carried by wind sand to be buried and invaded into a soil body, and the salinized soil which is easy to harden is combined, so that the physical structure of the whole soil body is complex, the underlying surface is hard, and a conventional tree planting machine or a pit digging machine cannot punch holes.
Therefore, in the vegetation restoration of the mining area of the arid area, in order to realize the purposes of digging a hole and drilling a hole on the underlying surface of a hard soil body, implanting shrubs and developing the vegetation restoration, a plant planting device for the ecological restoration of a tailing pond of the arid area and a specific using method thereof are provided.
