[0002] Demonstration forest is a typical forest area that concentrates on displaying advanced forestry technology, ecological restoration mode or economic benefit improvement path through scientific planning and management. Its core goal is to provide replicable and generalizable experience for similar areas through practical cases, and to promote high-quality development of forestry. Among them, demonstration forest environmental seedling raising is one of the key links. It specifically refers to the use of eco-friendly and resource-saving seedling raising technology in demonstration forest construction. Through optimization of seedling raising process, innovation of material application and scientific management, the collaborative development of seedling cultivation and environmental protection is realized. In the subsequent link of seedling cultivation, existing forest planting generally adopts the transplanted method, that is, after the seedlings grow to a certain height, they are transplanted to the target garden. However, the newly transplanted seedlings have not yet rooted in the soil and have weak resistance to environmental disturbances such as wind, and are prone to falling over. Therefore, auxiliary supports are usually needed to fix and support them.

[0003] A supporting auxiliary device for forest planting and seedling raising is disclosed in Chinese Patent No. CN218921168U.

The fixed platforms are provided with fixed plates, which are symmetrically provided with rope passing ears. The rope passing ears are movably connected with connecting ropes. The utility model supports the different directions of the forest through multiple fixed platforms, branches, lifting platforms and fixed plates. The fixed plates are connected together through the connecting ropes and the rope passing ears to stably support the forest. The rotatable supporting rods cooperate with the lifting adjustment of the lifting platforms to support the forest in rugged or inclined sections, and have wide application range.

[0004] However, the above-mentioned prior art has the following disadvantages: during use, as the seedlings grow, the supporting auxiliary device will limit them, resulting in the need to disassemble the supporting auxiliary device later.

[0038] The working principle of the application is: when using the device, first select the flat soil around the root of the seedling, align the tip of the V-shaped insertion plate 11 with the soil, and gradually insert it by using the cutting effect of the blade on the soil. In the initial state, the limiting plate 14 is inserted into the installation slot 12 at the top end of the insertion plate 11, and the top end of the limiting plate 14 is simultaneously clamped into the limiting slot one 17 of the connecting rod 16 and the limiting slot two 23 at the bottom end of the main rod 21, and at this time the activation hole one 13 and the activation hole two 15 are in a staggered state, the rotating column 22 is inserted into the rotating hole 18 of the connecting rod 16 to realize rotating connection. When installing the supporting part 2, first loosen the fixed nut 211, slide the installation bolt 27 along the lifting groove 26 at the side end of the main rod 21, and quickly position according to the height of the seedling. After preliminarily tightening the fixed nut 211, insert the adjusting rod 29 into the fixed slot 28 of the installation bolt 27, rotate the adjusting rod 29 to make the supporting plate 210 close to the main stem of the seedling, until a certain gap is left between the supporting plate 210 and the surface of the seedling, and finally completely tighten the fixed nut 211 to ensure that the installation bolt 27 and the adjusting rod 29 are fixed in position, avoiding loosening during the supporting process.

After three to six months, the root system of the seedling gradually extends, when the root system drills into the overlapping area of the activation hole one 13 and the activation hole two 15, the root system continues to thicken, which generates a downward pushing force, slowly pushing the limiting plate 14 to move downward along the installation slot 12, until the limiting plate 14 completely exits the limiting slot one 17 and the limiting slot two 23, releasing the rigid constraint on the supporting part 2. At this time, the main stem of the seedling continues to thicken with growth, generating a radial expansion force to push the main rod 21, making the rotating column 22 slowly rotate around the rotating hole 18, and finally naturally separating from the support of the seedling. During the insect repellent process, the natural wind drives the fan blade 33 to rotate, the fan blade 33 makes the rotating rod 32 rotate synchronously, and the water droplet-shaped top block 34 on the outer surface of the rotating rod 32 abuts against the triangular top plate 311 at the bottom end of the material taking plate 37 once every revolution, pushing the material taking plate 37 to move upward. During the upward movement, the inverted V-shaped top end of the material taking plate 37 penetrates through the bottom end of the V-shaped flow guide plate 35 and inserts into the upper powder, at this time the material taking plate 37 is completely immersed in the powder, the powder enters the cavity two 38 through the feeding slot 39, and after the top block 34 continues to rotate and separates from the top plate 311, the material taking plate 37 falls back under the action of gravity, the powder in the cavity two 38 falls through the discharge slot 310, first contacts the top end of the triangular top plate 311 and is diverted to both sides, evenly falls into the filling area at the bottom end, and finally is blown out from the discharge hole 31 with the natural wind, forming an insect repellent belt around the seedling. After the support is released, the components of the device gradually degrade under the action of soil microorganisms, without the need for manual recycling, and the whole process is zero pollution.By the V-shaped plug-in plate 11 of the limiting piece 1 and the blade edge design, the overall stability of the soil pressure enhancement device can be enhanced, the blade edge can greatly reduce the resistance of insertion into different quality soils, and the plug-in plate 11 can be quickly fixed into the soil to ensure the misalignment of the activation hole one 13 and the activation hole two 15 and the double clamping groove structure of the limiting plate 14, and the clamping limiting groove one 17 and the bottom end of the supporting piece 2 are clamped, forming a rigid limiting when the seedling root system does not reach the growth threshold, avoiding loosening of the supporting piece 2, and when the root system naturally grows into the hole position overlapping area and pushes the limiting plate 14 downward, the limiting can be automatically released without manual operation, which can adapt to the growth rhythm of the seedling, realize the full-cycle automation of supporting and releasing, and through the precise cooperation of the rotating column 22 of the supporting piece 2 and the rotating hole 18, the supporting piece 2 can rotate flexibly around the connecting rod 16, accurately adapt to the expansion demand of the thickening of the main stem of the seedling, and the lifting groove 26 at the side end of the main rod 21 and the sliding structure of the mounting bolt 27 can freely adjust the position of the supporting plate 210 according to the height of the seedling, and the plug-in and threaded connection design of the adjusting rod 29 in the fixed groove 28 can quickly adapt to the main stem of the seedling with different thicknesses, ensuring that the supporting plate 210 always fits with appropriate force, avoiding over-loosening to cause tilting and preventing over-tightening to damage the skin, realizing the dynamic balance of supporting strength and growth demand, through the linkage structure of the fan blade 33 and the rotating rod 32 of the pest control piece 3, the rotation can be driven by natural wind without additional power, the periodic abutment design of the water drop-shaped top block 34 and the triangular top plate 311 can push the material taking plate 37 to reciprocate up and down, and the cooperation of the inverted V-shaped top end and the V-shaped guide plate 35 can accurately insert into the medicine powder area to take material, the through structure of the feeding groove 39 and the cavity two 38 realizes temporary storage of the medicine powder, and the triangular top plate 311 in the discharge groove 310 divides the medicine powder into two sides to ensure uniform scattering to the bottom end of the medicine filling area, and finally blows out through the discharge hole 31, forming an automatic pest control process from material taking to spreading, improving the stability of medicine powder utilization rate and pest control effect.
