Description

Technical Field

[0001] This utility model belongs to the field of ancient tree protection technology, and more specifically relates to a root water retention structure for the protection of ancient trees. Background Technology

[0002] Ancient and famous trees are a precious legacy from nature, representing important species, landscape, and ecological resources. They embody traditional culture, record the historical changes of cities, and possess significant ecological, economic, and scientific research value. Due to prolonged neglect, the area around the roots of ancient and famous trees often suffers from severe localized waterlogging or drought. Furthermore, human activities such as road construction and building construction reduce soil porosity and alter physical properties, inhibiting root growth and reducing the efficiency of water and mineral nutrient absorption and transport. This leads to yellowing leaves, increased dead branches, and overall tree weakness. Therefore, improving the environment around the roots of ancient trees to facilitate water and fertilizer management is crucial. Existing technologies, such as CN217742279U, only include a water collection mechanism at the base of the tree to drain excess water from the roots. This does not recover water from the upper and surface soil layers, nor does it simultaneously achieve root ventilation through the water collection device.

[0003] Therefore, how to provide a root water retention structure for the protection of ancient trees that can simultaneously achieve drainage, water supply and ventilation and provide nutrients to the root system of ancient trees is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a root water retention structure for the protection of ancient trees, which has the advantages of simultaneously achieving drainage, water supply and ventilation, and providing nutrients to the roots of ancient trees.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A root system water retention structure for the protection of ancient trees includes a shallow water collection unit, a circulation unit, a nutrient drip irrigation unit, and a water tank. The shallow water collection unit is arranged in a ring around the shallow soil around the ancient tree to collect accumulated water around the tree or to provide shallow water for the tree. The circulation unit connects the water tank to the shallow water collection unit to circulate the water in the tank and the shallow water collection unit. Multiple nutrient drip irrigation units are arranged around the ancient tree and penetrate the shallow water collection unit to reach deep into the soil, delivering nutrients and water to the deep root system of the ancient tree.

[0007] Furthermore, the shallow water collection unit includes an annular water collection trough, the sidewall of which is inclined to guide the surface water around the ancient tree into the annular water collection trough; a number of shallow drip irrigation holes are evenly arranged on the lower end face of the annular water collection trough to allow the water in the annular water collection trough to seep into the soil layer around the ancient tree.

[0008] Furthermore, a filter grid is also provided above the annular water collection tank to filter out leaves or branches falling from above.

[0009] Furthermore, the circulation unit includes a water collection pipe and a water supply pipe. One end of the water collection pipe is connected to the lower end of the annular water collection trough, and the other end is connected to the lower end of the water tank. A first water pump is installed on the water collection pipe to transport excess water from the annular water collection trough to the water tank. A filter screen is installed at the inlet of the water collection pipe. One end of the water supply pipe leads into the lower part of the water tank, and the other end leads into the upper part of the annular water collection trough. A second water pump is installed on the water supply pipe to input water from the water tank into the annular water collection trough.

[0010] Furthermore, the nutrient drip irrigation unit includes a nutrient tank at the top and a drip irrigation pipe at the bottom; the nutrient tank is filled with nutrient solution for the ancient tree, and a slow-flow hole is provided on the lower end face, which is connected to the drip irrigation pipe to slowly input the nutrient solution into the drip irrigation pipe; the drip irrigation pipe penetrates downward through the lower end face of the annular water collection trough, and penetrates deep into the soil to input nutrients and water into the deep root system of the ancient tree.

[0011] Furthermore, a ventilation opening is provided on the upper part of the side wall of the drip irrigation pipe above the annular water collection trough for ventilation of the deep root system of the ancient tree; a water inlet is provided on the middle part of the side wall of the drip irrigation pipe inside the annular water collection trough for water supply to the deep root system of the ancient tree; and several drip irrigation holes are provided on the upper and lower parts of the side wall of the drip irrigation pipe below the annular water collection trough for supplying nutrients and water to the deep root system of the ancient tree.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model provides a root water retention structure for the protection of ancient trees. By setting drip irrigation pipes around the ancient tree and extending them into the deep soil, and by setting ventilation openings, water inlets, and drip irrigation holes on the side walls, water in the annular water collection trough can be introduced into the deep soil and provide nutrient water for the deep root system. Furthermore, by using a circulation unit to connect the water tank and the shallow water collection unit, the normal water supply to the ancient tree can be guaranteed during waterlogging or drought, while simultaneously achieving drainage, water supply, and ventilation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see the appendix Figure 1-3 This utility model provides a root system water retention structure for the protection of ancient trees, including a shallow water collection unit 2, a circulation unit 4, a nutrient drip irrigation unit 5, and a water tank 3. The shallow water collection unit 2 is arranged in a ring around the shallow soil of the ancient tree 1 to collect accumulated water around the ancient tree 1 or to provide a shallow water source for the ancient tree 1. The circulation unit 4 connects the water tank 3 to the shallow water collection unit 2, enabling the water in the water tank 3 and the shallow water collection unit 2 to circulate. Multiple nutrient drip irrigation units 5 are arranged along the ancient tree 1, with their lower parts penetrating through the shallow water collection unit 2 to reach deep into the soil, delivering nutrients and water to the deep root system of the ancient tree 1.

[0022] The shallow water collection unit 2 includes an annular water collection trough with inclined sidewalls to guide surface water around the ancient tree into the trough, preventing excessive water accumulation from causing root rot. Several shallow drip irrigation holes are evenly distributed on the lower surface of the annular water collection trough to allow water to seep into the soil around the ancient tree, providing moisture to the shallow root system. A filter grid is also installed above the annular water collection trough to filter fallen leaves or branches.

[0023] The circulation unit 4 includes a water collection pipe 6 and a water supply pipe 7. One end of the water collection pipe 6 is connected to the lower end of the annular water collection trough, and the other end is connected to the lower end of the water tank 3. A first water pump 8 is installed on the water collection pipe 6 to transport excess water from the annular water collection trough to the water tank 3. A filter unit is installed at the inlet of the water collection pipe 6 to filter impurities in the water. A filter screen is installed at the inlet of the water collection pipe 6 to filter impurities in the water and prevent clogging. One end of the water supply pipe 7 leads into the lower part of the water tank 3, and the other end leads into the upper part of the annular water collection trough. A second water pump 9 is installed on the water supply pipe 7 to input water from the water tank 3 into the annular water collection trough. When the water in the annular water collection trough becomes excessive due to water accumulation around the ancient tree or rain, the first water pump 8 is activated to transport the excess water to the water tank 3; when the area around the ancient tree is too dry, the second water pump 9 is activated to input water into the annular water collection trough and provide moisture to the shallow soil through the shallow drip irrigation holes at the lower end of the annular water collection trough.

[0024] The nutrient drip irrigation unit 5 includes a nutrient tank 10 located at the top and a drip irrigation pipe 11 located at the bottom. The nutrient tank 10 is filled with nutrient solution for the ancient tree 1, and a slow-flow hole is provided on the lower end face, which is connected to the drip irrigation pipe 11 to slowly input the nutrient solution into the drip irrigation pipe 11. The drip irrigation pipe 11 penetrates downward through the lower end face of the annular water collection trough, and penetrates deep into the soil to input nutrients and water into the deep root system of the ancient tree 1. A ventilation opening is provided on the upper part of the side wall of the drip irrigation pipe 11 above the annular water collection trough for ventilation of the deep root system of the ancient tree 1; a water inlet is provided on the middle part of the side wall of the drip irrigation pipe 11 inside the annular water collection trough for water supply to the deep root system of the ancient tree 1; water in the annular water collection trough flows into the drip irrigation pipe 11 through the water inlet, diluting the nutrient solution flowing down from above and transporting it downward to the deep soil; several drip irrigation holes are provided on the upper and lower parts of the side wall of the drip irrigation pipe 11 below the annular water collection trough for supplying nutrients and water to the deep root system of the ancient tree 1.

[0025] Multiple nutrient drip irrigation units 5 are provided, and staff can set various nutrient solutions with different compositions in the nutrient box 10 to provide different nutrient solutions to different parts of the root system of the ancient tree 1, ensuring the healthy growth of the ancient tree 1. Furthermore, by setting the concentration of the nutrient solution, the root system of the ancient tree can be induced, which facilitates root management.

[0026] The working process of this utility model is as follows: When the soil around the ancient tree 1 is dry, the second water pump 9 is started to input water into the annular water collection trough. The shallow drip irrigation holes at the lower end of the annular water collection trough seep water into the surrounding shallow soil, providing moisture to the shallow root system around the ancient tree 1. Using the water inlet in the middle of the drip irrigation pipe 11, the water in the annular water collection trough is transported downwards through the water inlet to the deeper soil, providing moisture to the deep root system around the ancient tree 1. At the same time, the nutrient tank 10 is filled with nutrient solution, which, after being diluted with the water entering through the water inlet, can provide the necessary nutrients and water for the growth of the roots of the ancient tree 1. In addition, the drip irrigation pipe 11 also has the effect of root ventilation. When there is water accumulation around the ancient tree 1 or heavy rainfall, the first water pump 8 is started to transport excess water to the water tank 3 to prevent excessive moisture around the ancient tree 1 from affecting the root system. Staff can set various nutrient solutions with different compositions in the nutrient box 10, which can provide different nutrient solutions to different parts of the root system of the ancient tree 1, ensuring the healthy growth of the ancient tree 1. Furthermore, by setting the concentration of the nutrient solution, the staff can induce the root system of the ancient tree, which facilitates root management.
