Description

Technical Field

[0001] The invention relates to the technical field of sand fixation and management, in particular to a device for ecological restoration of vegetation in sandy land. Background Art

[0002] The current methods of desert control include biological sand fixation, physical sand fixation, chemical sand fixation, etc. Biological sand fixation is mainly achieved through enclosure and planting of plants, while physical sand fixation is to set up obstacles or solid objects on the edge of the desert to prevent the movement of mobile sand dunes. In desertified areas, single plants grow very slowly, and physical sand fixation technology and cost are relatively high. At present, chemical sand fixation has poor environmental adaptability, and some sand fixation materials will cause secondary pollution to the environment.

[0003] At present, people mainly adopt the combination of sand-fixing and tree-planting to curb the process of desertification, and have achieved certain results. However, in the process of preventing and controlling sand and transplanting trees, because the trees are just planted in the sandy ground, the root foundation is weak and external support frames are needed to support the trees to help them take root quickly and stably. The existing support frame structures are mostly handmade by tree planting staff, which is time-consuming and labor-intensive and cannot be reused. In addition, the support frame needs to be fixed by binding or nailing into the tree, which causes certain damage to the tree, and the fixing strength varies greatly due to the construction technology.

[0004] In addition, after searching, a kind of fixing frame for forest protection and tree planting is disclosed in the publication (announcement) number: CN214628625U. Through the connection block and the connection rod, when using the device, the gasket is first pressed to the appropriate height of the tree through the connection block, and then the steel ball is inserted into the groove of another connection block, and the four connection blocks are combined and connected. The spring pulls the connection rod to shrink in the connection block, so that the combined connection block fits on the tree bark, and the connection block is fixed on the tree. As the tree grows and becomes thicker, the connection rod is pulled out of the connection block, so that the inner diameter of the combined connection block becomes larger, preventing the fixing frame from causing damage to the tree as the tree grows. However, in actual use, it is found that it has a certain effect on the windward support of the tree, but in areas with severe land desertification, one end of it relies on the ground for support. The support effect is limited, and it cannot cope with soft land and severe desertification geology, and it cannot support sandy plants with complex and multi-faceted wind directions. In view of this, research and improvement are carried out on the existing problems, and a sand vegetation ecological restoration device is provided to solve the current problems of tree planting fixing frames damaging trees and poor supporting effects. The purpose is to achieve the purpose of solving problems and improving practical value through this technology. Summary of the invention
