Description

Technical Field

[0001] The present invention relates to the technical field of ancient tree rejuvenation, and specifically provides an ancient tree rejuvenation device and method. Background Technique

[0002] When the growth potential of an ancient tree weakens, one of the main reasons is that the growth environment of the ancient tree roots has undergone adverse changes, mainly manifested in aspects such as water, gas, and nutrients. Specifically, some ancient trees show weakened growth potential, with phenomena such as smaller and yellower leaves in normal seasons.

[0003] For different reasons of weakness, different repair measures need to be matched. For example, for weakness caused by damage or trunk rot of ancient trees, measures such as cleaning rot, applying surface agents, and plugging are required; if it is pests and diseases, treatment for pests and diseases is needed; if it is due to soil compaction and too small growth space, resulting in difficult water infiltration and difficult gas exchange in the soil, the measures for ancient tree rejuvenation are often to remove weeds, loosen the soil, drill holes and bury ventilation pipes to increase air permeability, and at the same time irrigate nutrient solutions during burial to assist growth.

[0004] For weakness caused by insufficient air permeability and nutrients, generally, a ventilation pipe is used for liquid irrigation to directly supply liquid medicine or nutrient agents to the roots of big trees. However, the holes on the outer wall of the ventilation pipe are often blocked by the soil brought in after initial perfusion, resulting in poor ventilation effect and limited rejuvenation effect. Moreover, after the ventilation pipe is implanted, most of the time a large amount of nutrient solution is perfused at one time, resulting in too much water and excessive fertility in the roots, which has the opposite effect on some ancient trees.

[0005] Based on this, the present invention designs an ancient tree rejuvenation device and method to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an ancient tree rejuvenation device and method to solve the problems raised in the above background technique, that is, the holes on the outer wall of the ventilation pipe are often blocked by the soil brought in after initial perfusion, resulting in poor ventilation effect and limited rejuvenation effect; and after the ventilation pipe is implanted, most of the time a large amount of nutrient solution is perfused at one time, resulting in too much water and excessive fertility in the roots, which has the opposite effect on some ancient trees.

[0007] To achieve the above purpose, the present invention provides the following technical solution: It includes a ventilation pipe, the outer wall of the ventilation pipe is evenly provided with ventilation holes, a protective pipe is sleeved outside the ventilation pipe, the outer wall of the protective pipe is evenly provided with ventilation windows, and a breathable protective layer is filled between the ventilation pipe and the protective pipe; a round hole top cover is covered on the top of the protective pipe, and a protective cap is installed on the top of the ventilation pipe, and the protective cap is used for guiding wind.

[0008] As a further solution of the present invention, an air-permeable branch pipe is communicated with the side wall of the air-permeable pipe. Air holes are formed in the outer wall of the air-permeable branch pipe, and the air holes are arranged downward.

[0009] As a further solution of the present invention, a multi-way pipe is connected to the top of the air-permeable pipe. A perfusion pipe is communicated with the side wall of the multi-way pipe. A perfusion hole is formed at the bottom of the perfusion pipe, and the perfusion hole is arranged downward.

[0010] As a further solution of the present invention, the inner ends of the perfusion pipes are commonly communicated with a perfusion ring. A feeding pipe is communicated with the top of the perfusion ring. A sealing plug is installed in the feeding pipe. A pressing ring is slidably arranged in the perfusion ring. When the pressing ring moves upward, the liquid in the perfusion ring is extruded into the perfusion pipes and extruded through the perfusion holes.

[0011] As a further solution of the present invention, a partition piece is fixedly connected in the middle of the perfusion ring. The pressing ring is located above the partition piece. The space below the partition piece is a communicating ring, and the communicating ring is communicated with the air-permeable branch pipe. An active air intake assembly is communicated with the side wall of the communicating ring. The active air intake assembly can first push the pressing ring upward and then intake air into all the air-permeable branch pipes through the communicating ring.

[0012] As a further solution of the present invention, the active air intake assembly includes an intermediate pipe installed in the communicating ring. A slow-release pipe is communicated above the intermediate pipe, and a ventilation pipe is communicated below the intermediate pipe. The slow-release pipe and the ventilation pipe are arranged in a front-back staggered manner. A reversing plug is slidably connected in the intermediate pipe. A push rod is fixedly connected to the rear end of the reversing plug. When the pressing ring moves upward, the push rod moves to block the slow-release pipe.

[0013] As a further solution of the present invention, a communicating liquid injection channel is arranged between the intermediate pipe of the communicating ring and the top of the perfusion ring. The push rod is located in the liquid injection channel. A return spring is installed between the reversing plug and the liquid injection channel. The reversing plug is a hollow plug and the tail end is transparent.

[0014] As a further solution of the present invention, a hollowed-out piece and a hollow piece are fixedly installed in the air-permeable branch pipe. The hollow piece and the hollowed-out piece are arranged up and down, and a sealing piece is movably arranged between the two. The hollow piece and the hollowed-out piece are located above the connection between the air-permeable branch pipe and the multi-way pipe.

[0015] As a further solution of the present invention, multiple groups of the active air intake assemblies are provided and are evenly dispersed between two adjacent air-permeable branch pipes. The inner side of the communicating ring is communicated with all the intermediate pipes through a dispersion ring, and an air inlet pipe is communicated with the outer side of the dispersion ring.

[0016] A method for rejuvenating ancient trees includes the following steps: Dig an annular groove and drill air-permeable holes in the circumferential direction of the ancient tree. The depth of the air-permeable holes is 50-80 CM. Pour nutrient solution into the annular groove and the air-permeable holes; Insert a breathable tube into the ventilation hole, then sleeve a protective tube, fill a breathable protective layer between the breathable tube and the protective tube, cover the round hole top cover after filling, and install a protective cap at the top end of the breathable tube protruding from the ground; Install the breathable branch pipe and the perfusion pipe on the side wall of the breathable tube through a multi-way pipe, place the perfusion ring in the dug annular groove and connect it with the breathable branch pipe and the perfusion pipe, and then backfill and bury the perfusion ring and the breathable tube so that the protective cap and the end of the liquid supplement pipe are above the ground; Add nutrient solution to the perfusion ring through the liquid supplement pipe, and then install a sealing plug for closing; Install an air inlet device through the air inlet pipe. The air inlet device inflates the communication circle. The gas filled first pushes the pressure ring upward through the slow-release pipe for air inlet, and then squeezes out a certain amount of the nutrient solution in the perfusion ring. Then close the slow-release pipe and open the ventilation pipe, and actively disperse the gas to each breathable branch pipe through the communication circle to achieve pressurized active ventilation.

[0017] Compared with the prior art, the beneficial effects of the present invention are: Particulates such as gravel and ceramsite are filled between the breathable tube and the protective tube as the breathable protective layer, which can not only protect the ventilation holes of the internal breathable tube from being blocked by fine soil, ensure good air permeability, but also increase the breathable area and have a protective effect on the internal breathable tube to avoid breakage; horizontal shallow ventilation is realized through the breathable branch pipe, and the two are used in combination to have a better effect on the repair and growth absorption of the root system.

[0018] The nutrient solution in the perfusion ring can be squeezed upward through the pressure ring and extruded through the perfusion holes, realizing the quantitative slow-release effect of the nutrient solution, which is especially suitable for the rejuvenation of ancient trees that cannot be infused with too much liquid medicine at one time and need to recover slowly, ensuring the supplement effect of the nutrient solution and avoiding adverse effects caused by excessive supplementation.

[0019] Realize active downward pressure blowing for deep ventilation and air exchange. Cooperating with the active ventilation of the breathable branch pipe can cover the root system of ancient trees to a large extent, enabling it to obtain a better breathing effect, facilitating the exchange of waste gas, and enabling the ancient trees to rejuvenate and obtain the required nutrients.

[0022] Please refer to Figures 1-11 , the working principle of the technical solution provided by the present invention is as follows: In Embodiment 1, before the present invention is used, holes need to be evenly drilled in the circumferential direction of the ancient tree, and the drilling depth is preferably 50 - 80 CM. Insert the prepared air-permeable pipe 1 and the connected protection pipe 3 into the holes together. Particulate matters such as stones and ceramsite have been filled between the air-permeable pipe 1 and the protection pipe 3 as an air-permeable protection layer, which can not only protect the air-permeable holes 2 of the internal air-permeable pipe 1 from being blocked by fine soil, ensure good air permeability, but also increase the air-permeable area and have a protection effect on the internal air-permeable pipe 1 to avoid damage.

[0023] Installing a round hole top cover 5 on the top of the protection pipe 3 can prevent a large amount of soil from entering the protection pipe 3 from the top, and try to retain the natural gap between the stones or ceramsite to ensure air permeability; at the same time, a protection cap 6 is added to the top of the air-permeable pipe 1. The protection cap 6 can be a non-powered wind cap to help the air in the pipe discharge outward and conduct air exchange, or it can be an impeller that sucks air centripetally into the pipe to help fresh air enter the air-permeable pipe 1; specifically, which structure to choose as the protection cap 6 can be determined according to the situation of the ancient tree. If the ancient tree has rotten roots, it is preferred to choose the non-powered wind cap type to help discharge the waste gas generated by the rotten roots.

[0024] On the basis of Embodiment 1, an air-permeable branch pipe 7 is added. Longitudinal deep air permeability is achieved through the air-permeable pipe 1, and transverse shallow air permeability is achieved through the air-permeable branch pipe 7. The combination of the two can achieve better effects on the repair and growth absorption of roots.

[0025] Embodiment 2: On the basis of Embodiment 1, a perfusion pipe 10, a perfusion ring 12, etc. are added, and the perfusion pipe 10 is connected and installed with the air-permeable pipe 1. At this time, by removing the sealing plug 14, the prepared nutrient solution or treatment solution can be poured into the perfusion ring 12 through the feeding pipe 13. Then, the nutrient solution is dispersed and transported to the perfusion pipes 10 in all directions through the perfusion ring 12, and finally flows out through the perfusion holes 11, thereby achieving large-area drug delivery coverage. If enough nutrient solution is poured in, it can also flow into the air-permeable pipe 1 through the holes at the end of the perfusion pipe 10, and then achieve deep and rapid drug delivery through the diversion of the air-permeable pipe 1.

[0026] On the basis of Embodiment 2, the perfusion holes 11 are set as micropores, or rubber sheets with cross cuts or filter sheets are installed in the perfusion holes 11. When the perfusion ring 12 is filled with the nutrient solution, the perfusion pipes 10 are in a state of being full but not overflowing. By lifting the pressing ring 15 upward, the nutrient solution in the perfusion ring 12 can be squeezed upward through the pressing ring 15 and extruded through the perfusion holes 11. By controlling the amplitude and frequency of the upward movement of the pressing ring 15, the single perfusion volume and perfusion frequency can be controlled, thereby achieving the quantitative slow-release effect of the nutrient solution. This is especially suitable for the rejuvenation of ancient trees that cannot be perfused with too much medicine at one time and need to recover slowly, ensuring the supplementary effect of the nutrient solution and avoiding adverse effects caused by excessive supplementation.

[0027] Embodiment 3. On the basis of Embodiment 2, a connecting ring 17 is provided below the perfusion ring 12, which is integrally formed with the perfusion ring 12 and buried underground to protect the detail components together within the connecting ring 17, extending the service life of the device; initially, air is intermittently supplied into the air inlet pipe 29 through an external air inlet member 30. The entering gas first enters the space below the pressure ring 15 through the open slow-release pipe 19, and then pushes the pressure ring 15 upward, squeezing the liquid above the pressure ring 15 upward and discharging it, and then flowing out through the perfusion pipe 10 (the perfusion holes 11 are set as micro-holes or rubber sheets with cross cuts are installed in the perfusion holes 11 or filter sheets are installed, all of which are to prevent the liquid from being easily extruded from the perfusion holes 11 when under pressure, ensuring the triggering of the reversing plug 21); when the pressure ring 15 moves upward, the same liquid will be squeezed into the tail end of the intermediate pipe 18 through the liquid injection channel 23, and then push the push rod 22 forward, thereby pushing the reversing plug 21 to move towards the slow-release pipe 19 until it blocks the slow-release pipe 19. At this time, the intermediate pipe 18 is communicated with the ventilation pipe 20 through the tail end of the reversing plug 21, and external air enters the connecting ring 17 through the ventilation pipe 20 and then disperses into each breathable branch pipe 7. When the external air flow enters the breathable pipe 1 through the breathable branch pipe 7, an upward flow will be generated, which will push the sealing piece 27 upward. The sealing piece 27 is attached to the hollow piece 26 to block the upper end of the breathable pipe 1, so that the air flow can only flow between the holes below the sealing piece 27, thus realizing active downward pressure blowing for deep ventilation and air exchange. Cooperating with the active ventilation of the breathable branch pipe 7 can cover the ancient tree roots to a large extent, enabling it to obtain a better breathing effect, facilitating the replacement of waste gas, and enabling the ancient tree to rejuvenate and obtain the required nutrients.

[0028] When the pressure ring 15 gradually extrudes all the internal liquid outwards during its upward movement and stops at the current position, the liquid in the liquid injection channel 23 also gradually loses pressure, and then under the action of the return spring 24, the reversing plug 21 is pulled back to block the ventilation pipe 20 again, and then returns to the original state to facilitate the next cycle of squeezing and releasing nutrient solution and subsequent active ventilation.

[0029] The amount of liquid released each time of irrigation is related to the elastic force of the return spring 24. The greater the elastic force of the return spring 24, the greater the pressure generated by the upward movement of the pressure ring 15, which is sufficient to overcome the elastic force of the return spring 24 through the liquid injection channel 23, making it lengthen and be stretched, and then pushing the reversing plug 21 to move. Therefore, the amount of the extruded liquid will be relatively large.

[0030] When the liquid in the perfusion ring 12 is used up, by opening the sealing plug 14 and using a tool to press the pressure ring 15 to the bottom of the perfusion ring 12 through the feeding pipe 13, at this time, re-filling is carried out again, and then the sealing plug 14 is covered to block the bottom of the feeding pipe 13.

[0031] The air inlet member 30 can be a fan that starts intermittently and regularly, or can be such as Figure 11The bellow with an arc-shaped elastic cover plate shown in the figure has an air intake grille opened at the top of the arc-shaped elastic cover plate, and a dome cap covers the top. A compression plug is slidably arranged inside the bellow. A sliding rod is fixedly connected between the dome cap and the compression plug. The bellow with the arc-shaped elastic cover plate is buried underground, and the arc-shaped elastic cover plate and the dome cap are above the ground. When someone walks by, the dome cap will be stepped on to block the air intake grille, and then the compression plug will be pressed down, so that the air in the bellow can only be discharged through the air inlet pipe 29. Furthermore, the function of first pushing the pressing ring 15 through the slow-release pipe 19 to extrude and quantitatively release nutrient solution and then actively filling fresh air into the air permeable branch pipe 7 and the air permeable pipe 1 can be realized. As long as someone walks by the air intake part 30, it can be triggered without other complex equipment and without long-term supervision. The rejuvenation and restoration measures of ancient trees can be realized through people's natural walking, which is more in line with the natural law.

[0032] Among them, the air permeable branch pipe 7 is located below the perfusion pipe 10, and the air holes 8 and the perfusion holes 11 of both are arranged downward to avoid being blocked when buried. At the same time, the ventilation position of the air permeable branch pipe 7 is located below the perfusion hole 11 to avoid hardening of the perfusion position; filling particles such as gravel or ceramsite soil at the air permeable branch pipe 7 has a better effect.

[0033] The perfusion ring 12 can be set as two symmetrical halves, and thus can be arranged in the annular groove dug for restoration, saving the time required for burial; through the connecting pipe, the two halves of the perfusion ring 12 and the connecting ring 17 can be correspondingly connected and communicated, realizing one-side action and two-side response, making more efficient use of kinetic energy, comprehensively performing perfusion and ventilation, and avoiding one-sided bias.
