Description

Technical Field

[0001] The utility model belongs to the field of tree terminal bud protection devices, in particular to a simple sand-growing evergreen tree terminal bud protection device. Background Art

[0002] Evergreen coniferous trees such as Larix gmelinii and Picea sylvestris are widely used in sand prevention and control as excellent tree species due to their light-loving, cold-resistant and drought-resistant characteristics. For example, in the Saihanba Mechanical Forest Farm, which has grown from one tree to a "sea", Larix gmelinii and Picea sylvestris can be seen everywhere. The "Three Norths" shelterbelt project, the Beijing-Tianjin sand source project and other projects also plant Larix gmelinii and Picea sylvestris as important tree species for windbreak and sand fixation.

[0003] Forestry people often say that seedling planting requires "three parts planting and seven parts management". Management is particularly important for ecological governance projects implemented in pastoral areas where people make a living by raising livestock. For apical dominant tree species such as Scots pine and spruce, the destruction of the terminal buds will seriously affect the vertical growth and maturity of the seedlings. Therefore, protecting the terminal buds of the seedlings from being damaged is one of the key factors for the success of management. The current management methods usually include physical enclosures and manual patrols, which have a great effect on management. However, due to the destruction of fences and inadequate manual patrols, cases of cattle and sheep gnawing and damage to the project area are common. Therefore, it is necessary to design special protective devices for the terminal buds. Summary of the invention

[0020] The preferred solution is Figures 1 to 3 As shown, a simple terminal bud protection device for desert evergreen trees comprises an external protection tube 1, an internal extension tube 2 is detachably provided inside the external protection tube 1, an enlarged base 8 is provided at the bottom of the internal extension tube 2, a U-shaped support seat 9 is provided at the bottom of the enlarged base 8, and a protective spike is provided outside the external protection tube 1.

[0021] The terminal bud protection device is mainly composed of an external protection tube 1, an internal extension tube 2, and a U-shaped support seat 9; both the external protection tube 1 and the internal extension tube 2 are open-ended structures. The external protection tube 1 is provided with a longitudinal internal slide groove 3, a transverse limit slide groove 4, a clamping hole 6, a limit groove 10, and protective thorns 7, and a plurality of protective thorns 7 are arranged on the external protection tube 1. The upper part of the internal extension tube 2 is provided with a wedge-shaped buckle 5, and the lower part is provided with a U-shaped support seat 9.

[0022] Further, longitudinal sliding grooves 3 and transverse limiting sliding grooves 4 are provided on the inner wall of the outer protection cylinder 1. The longitudinal sliding grooves 3 and the transverse limiting sliding grooves 4 are communicated. A wedge-shaped buckle 5 is provided on the inner extension cylinder 2, and the wedge-shaped buckle 5 is matched with the longitudinal sliding grooves 3 and the transverse limiting sliding grooves 4. Right below the limiting position of the transverse limiting sliding groove 4, a downward pulling limiting groove 10 is provided, and the downward pulling limiting groove 10 is communicated with the transverse limiting sliding groove 4. A plurality of card holes 6 are provided on the downward pulling limiting groove 10, and the plurality of card holes 6 are arranged vertically. The card holes 6 are matched with the wedge-shaped buckle 5.

[0023] In this embodiment, degradable materials are selected to manufacture the outer protection cylinder 1 and the inner extension cylinder 2 respectively. The overall structure is cylindrical. The outer protection cylinder 1 is rotationally symmetric along the central axis. Longitudinal sliding grooves 3 and transverse limiting sliding grooves 4 are engraved on the inner wall of the protection cylinder. The longitudinal sliding grooves 3 are connected to the transverse limiting sliding grooves 4 from bottom to top.
