[0028] The tree trunk surrounding ring structure provided by the utility model embodiment will be described in detail below in combination with Figures 1-2 , through specific embodiments and application scenarios.

[0029] As Figure 1 and Figure 2As shown, this utility model provides a tree ring structure, which includes an inner layer 1, a middle layer 2, an outer layer 3 and a fixing layer 4 connected sequentially from the inside to the outside along its radial direction.

[0030] The inner layer 1 includes a fully degradable plant fiber sheet.

[0031] The middle layer 2 comprises a cellulose regenerated and degradable fabric. The cellulose regenerated and degradable fabric is adsorbed onto the outer surface of the fully degradable plant fiber sheet.

[0032] The outer layer 3 includes a first cellulose regenerated membrane 31 and a waterproof layer 32. The first cellulose regenerated membrane 31 is adhered to the outer surface of the cellulose regenerated and degraded fabric. The waterproof layer 32 is coated on the outer surface of the first cellulose regenerated membrane 31.

[0033] The fixing layer 4 includes a second cellulose regenerated membrane. The second cellulose regenerated membrane is adhered to the outer surface of the waterproof layer 32.

[0034] The outer side refers to the side 100 degrees away from the trunk, while the inner side is opposite to the outer side.

[0035] Specifically, such as Figure 1 As shown, the inner layer 1, middle layer 2, outer layer 3, and fixing layer 4 are tightly connected sequentially from the inside to the outside along the radial direction of the tree ring structure. The fully degradable plant fiber sheet is fibrous, soft, and thin. It is formed by dissolving natural cellulose in a suitable solvent and then processing it through combing and cutting during the spinning process. Compared to traditional rigid insect-repellent rings, the fully degradable plant fiber sheet adheres more tightly to the bark surface, reducing the gap between the tree ring structure and the bark surface, thus effectively blocking pests while preventing the tree ring structure from scratching the tree surface.

[0036] The middle layer 2 is formed by loosely laying plant fibers into a nonwoven cellulose regenerated and degradable fabric. This cellulose regenerated and degradable fabric serves as a support layer, possessing significant strength and toughness to support the fully degradable plant fiber sheets, the first cellulose regenerated membrane 31, and the second cellulose regenerated membrane. The fully degradable plant fiber sheets and the cellulose regenerated and degradable fabric are bonded together by molecular forces, achieving a tight fit. The first cellulose regenerated membrane 31 is adhered to the outer surface of the cellulose regenerated and degradable fabric. A waterproof layer 32 is applied to the outer surface of the first cellulose regenerated membrane 31 to ensure excellent waterproof performance of the inner layer 1, middle layer 2, and outer layer 3, guaranteeing the working durability of the tree ring structure.

[0037] The second cellulose regenerated membrane is bonded to the outer side of the waterproof layer 32 to provide external reinforcement for the entire tree ring structure and improve the overall strength of the tree ring structure.

[0038] The first regenerated cellulose film 31 and the second regenerated cellulose film are both regenerated cellulose preparation films. The fully-degradable plant fiber sheet, the cellulose regenerated degradable cloth, the first regenerated cellulose film 31 and the second regenerated cellulose film are tightly attached in sequence, which can effectively prevent pests from invading the inside of the tree trunk 100 or the branch, and has good pest prevention effect. The fully-degradable plant fiber sheet, the cellulose regenerated degradable cloth, the first regenerated cellulose film 31 and the second regenerated cellulose film can all be degraded in the environment, and after use, they can be directly discarded into the soil by the staff, without affecting the environment, and have good environmental protection performance.

[0039] In use, the user can cut the fully-degradable plant fiber sheet, the cellulose regenerated degradable cloth, the first regenerated cellulose film 31 and the second regenerated cellulose film into appropriate lengths according to the diameter of the tree trunk 100 or the branch, and wrap them around the tree trunk 100 or the branch to form a ring structure, which is tightly attached to the tree trunk 100 or the branch and forms a barrier on the surface of the tree trunk 100 or the branch, thereby preventing the invasion of pests. The tree ring structure is used before the start of the active period of pests or in the early stage of pest invasion, and has the most effective pest prevention effect.

[0040] The fully-degradable plant fiber sheet is used for tightly attaching to the surface of the tree trunk 100 or the branch to prevent the invasion of pests, and has good pest prevention effect. The waterproof layer 32 is used for waterproof protection of the tree ring structure, increasing the working durability of the tree ring structure. The second regenerated cellulose film is adhered to the outer side of the waterproof layer 32, and plays a reinforcing role. The fully-degradable plant fiber sheet, the cellulose regenerated degradable cloth, the first regenerated cellulose film 31 and the second regenerated cellulose film can all be degraded in the environment, and can be directly discarded into the soil by the staff, without affecting the environment, and have good environmental protection performance.

[0041] In some embodiments, as shown in FIG. 1, the first regenerated cellulose film 31 is adhered to the outer side of the cellulose regenerated degradable cloth through the first adhesive layer 5. The second regenerated cellulose film is adhered to the outer side of the waterproof layer 32 through the second adhesive layer 6. Figure 2 The first adhesive layer 5 is adhered between the outer side of the cellulose regenerated degradable cloth and the inner side of the first regenerated cellulose film 31 to adhere the cellulose regenerated degradable cloth and the first regenerated cellulose film 31 together, so that they are more tightly attached, and the pests are prevented from entering the gap between the cellulose regenerated degradable cloth and the first regenerated cellulose film 31 while ensuring the connection strength of the cellulose regenerated degradable cloth and the first regenerated cellulose film 31.

[0042]

[0043] ​Similarly, the first adhesive layer 5 is applied between the outer side of the waterproof layer 32 and the inner side of the second regenerated cellulose film to bond the waterproof layer 32 and the second regenerated cellulose film together, ensuring the connection strength of the waterproof layer 32 and the second regenerated cellulose film while making them fit more closely, preventing pests from entering the gap between the waterproof layer 32 and the second regenerated cellulose film.

[0044] Optionally, the first adhesive layer 5 and the second adhesive layer 6 are both degradable environment-friendly adhesives.

[0045] The degradable environment-friendly adhesive can naturally degrade into harmless substances within a certain period of time, avoiding long-term existence in the environment. The degradable environment-friendly adhesive can be a starch-based adhesive, a polylactic acid adhesive, a natural rubber adhesive, or a plant resin adhesive, etc., which can be decomposed, degraded, or biodegraded in the environment, preventing the tree ring structure from incomplete degradation in the soil and reducing environmental pollution.

[0046] The inner side of the fully degradable plant fiber sheet is a fiber hairy surface, which is used to fit the tree trunk 100 or branch. The fiber hairy surface can increase the roughness of the fully degradable plant fiber sheet, fill in the uneven concave or convex points of the tree trunk 100 or branch surface, improve the tightness of the fully degradable plant fiber sheet and the tree trunk 100 or branch surface, and achieve the effect of effectively blocking pests. The curled regenerated fiber is processed into a fiber sheet-shaped fully degradable plant fiber sheet, and the fiber hairy surface is soft and thin, which can avoid damage to the surface layer of the tree bark. At the same time, the inner side of the fully degradable plant fiber sheet is a fiber hairy surface, which can adsorb insect eggs on the tree trunk, and then remove a part of the insect eggs when the tree ring structure is removed.

[0047] In some embodiments, the fiber hairy surface is sprayed with an insecticide, which kills pests entering the tree ring structure and insect eggs attached to the tree, reducing plant diseases and insect pests.

[0048] In some embodiments, the waterproof layer 32 includes at least one of a paint layer and a hot melt adhesive layer.

[0049] In a specific embodiment, the waterproof layer 32 includes the paint layer and the hot melt adhesive layer from inside to outside along the radial direction of the tree ring structure. Specifically, the paint and the hot melt adhesive are applied to the outer side of the regenerated cellulose degradation cloth to form the paint layer and the hot melt adhesive layer. The paint layer and the hot melt adhesive layer are arranged on the outer side of the regenerated cellulose degradation cloth in sequence to ensure that the entire tree ring structure has better waterproof performance and improves the working durability of the tree ring structure.

[0050] Of course, the waterproof layer 32 can also be a single paint layer. For example, the paint layer is selected from yellow waterproof paint, which is brushed on the outer side of the regenerated cellulose degradation cloth.

[0051] In the case that the waterproof layer 32 comprises the paint layer and the hot melt adhesive layer in sequence from inside to outside along the radial direction of the tree ring structure, the thickness of the outer layer 3 is 40 microns to 50 microns. Alternatively, the thickness of the outer layer 3 can be 40 microns, 42 microns, 45 microns, 48 microns or 50 microns. Preferably, the thickness of the outer layer 3 is 45 microns.

[0052] In some embodiments, the grammage of the inner layer 1 is 120 g / m2to 150 g / m2, so as to ensure that the inner layer 1 has a better soft and thin effect, so that the fully biodegradable plant fiber sheet can be more closely attached to the surface of the tree trunk 100 or branch, preventing insect pests from invading. Alternatively, the grammage of the fully biodegradable plant fiber sheet can be 120 g / m2, 130 g / m2, 140 g / m2or 150 g / m2. Preferably, the grammage of the fully biodegradable plant fiber sheet is 130 g / m2.

[0053] In some embodiments, the grammage of the cellulose regenerated degradation cloth is 50 g / m2to 60 g / m2, so as to ensure that the cellulose regenerated degradation cloth has sufficient support strength and toughness.

[0054] Alternatively, the grammage of the cellulose regenerated degradation cloth can be 50 g / m2, 52 g / m2, 55 g / m2, 57 g / m2or 60 g / m2. The user can adaptively select the grammage of the cellulose regenerated degradation cloth according to the diameter of the tree trunk 100. For example, when the diameter of the tree trunk 100 is large, the grammage of the cellulose regenerated degradation cloth can be selected as 60 g / m2, so as to ensure the wrapping strength of the entire tree insect prevention ring to the tree trunk 100. When the diameter of the branch is small, the grammage of the cellulose regenerated degradation cloth can be selected as 50 g / m2, so as to reduce the waste of materials.

[0055] Preferably, the grammage of the cellulose regenerated degradation cloth is 55 g / m2.

[0056] In some embodiments, the axial length of the tree ring structure is 8 cm to 12 cm. The user can adaptively select the axial length of the tree ring structure according to the type of tree, the type of insect pest, the length of the tree trunk 100 or branch, and other actual conditions. The axial length of the tree ring structure should not be too short, otherwise it is difficult to play a better physical insect prevention role. The axial length of the tree ring structure should also not be too long, so as to ensure the air permeability of the tree or branch and the healthy growth of the tree trunk 100 or branch.

[0057] Alternatively, the axial length of the tree ring structure can be 8 cm, 8.5 cm, 10 cm, 11 cm or 12 cm.

[0058] Preferably, the axial length of the tree ring structure is 10 cm, which can reduce the shielding of the surface of the tree trunk 100 or branch while ensuring a better insect prevention effect, and ensure the healthy growth of the tree trunk 100 or branch.

[0059] Finally, it should be noted that the above examples are intended to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
