Description

Technical Field

[0001] This utility model relates to the technical field of ancient tree irrigation, and more specifically, to an intelligent irrigation system for ancient trees. Background Technology

[0002] Natural aging is the main cause of the decline and death of ancient trees. As the trees age, many ancient trees naturally age, their vitality weakens, their physiological functions gradually decline, photosynthesis weakens, and their root system's ability to absorb water and mineral nutrients becomes increasingly poor, failing to meet the tree's own survival needs. This causes their physiological metabolism to slowly become unbalanced, leading to the gradual withering of some branches and leaves, and ultimately, the tree's decline and death.

[0003] Ancient trees, due to their advanced age, have deep root systems. As they age, their root absorption capacity weakens, and surface water becomes insufficient to supply the roots, leading to nutrient deficiency. Patent number "CN215122930U" discloses an "irrigation device for ancient trees" that uses a water storage pipe to irrigate the roots. However, this device only passively provides sufficient water to the roots and cannot precisely control the amount of water and fertilizer. Furthermore, for ancient trees with weak root absorption capacity, even with sufficient water, the amount absorbed may not meet their physiological needs. In fact, excessive water may seep into the soil, which the roots cannot fully absorb, leading to root rot and death, ultimately impairing absorption and reducing the tree's lifespan. Utility Model Content

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] like Figure 1-3 As shown, this utility model discloses an intelligent irrigation system for ancient trees, including a tree pit 1. The upper end of the tree pit 1 is provided with an annular water conveying chamber 2. The lower end of the annular water conveying chamber 2 is connected to several water storage pipes 3. Several water permeable holes 31 are evenly provided on the water storage pipes 3. An annular mounting seat 4 is provided on the upper part of the outer side of the tree pit 1. An annular water conveying chamber 2 is installed in the annular mounting groove of the annular mounting seat 4. The annular water conveying chamber 1 and the annular water conveying chamber 2 are respectively connected to a water and fertilizer storage tank through a first conveying pipe and a second conveying pipe. The water and fertilizer storage tank is connected to a water and fertilizer dispensing device 5 through a third conveying pipe. The annular water conveying chamber 2 is connected to several vertically arranged fourth conveying pipes 6. The end of the fourth conveying pipe 6 is connected to a nozzle 7 facing the tree crown. Example

[0023] In this application, a cover 8 is provided at the upper end of the tree pit 1. The cover 8 prevents external rainwater from entering the root soil layer, especially for heavy rain or torrential rain. At the same time, it can prevent the water in the soil layer at the lower end of the cover 8 from evaporating rapidly under the hot sun. The inner side of the cover 8 is a conical structure, which can guide water and prevent water accumulation. At the same time, the conical structure can provide some support for the tree trunk.

[0024] In this application, the water and fertilizer storage tank includes storage tank 9 and storage tank 10. The water and fertilizer stored in storage tank 9 are used for root irrigation, while the water and fertilizer in storage tank 10 are used for irrigation of the tree canopy. A soil nutrient sensor and a soil moisture sensor are installed in the tree pit 1. These sensors periodically test the soil nutrients and moisture in the root soil layer of the ancient tree and transmit the signals to a control terminal. The control terminal has pre-set data on the appropriate soil nutrient and moisture requirements of the ancient tree roots (estimated in advance based on factors such as the tree species, age, growth status, and season). Based on the missing nutrient and moisture content, the water and fertilizer preparation device 5 can be used to replenish the nutrients and moisture. (Regarding the space within tree pit 1, which is of known size), several fertilizer injection pipes 5-2 are connected to different fertilizer concentrate storage tanks, such as nitrogen, phosphorus, and potassium fertilizer concentrate storage tanks with known concentrations, and rejuvenation drug concentrate storage tanks with known concentrations. The control terminal controls different amounts of fertilizer concentrate and different amounts of water to enter the preparation tank 5-1 through an electric control valve and a flow meter until the required amount in the soil layer of the ancient tree root system is met. After being stirred evenly by the stirrer 5-4, it can be pumped into the storage tank 9 by the second water pump. The water and fertilizer solution in the storage tank 9 can flow by gravity into the water storage pipe 3, and finally seep into different locations in the root soil layer through the permeable holes 31, thereby maintaining an appropriate range of nutrients and water in the soil layer of the ancient tree root system. The leaves and bark of the ancient tree crown have a weaker absorption capacity than the root system. Therefore, in order to avoid wasting fertilizer, the principle of more water and less fertilizer is adopted when preparing water and fertilizer. Similarly, the corresponding configuration data is preset in the control terminal. The control terminal automatically configures the water and fertilizer through the water and fertilizer configuration device 5. After configuration, the water is pumped into the storage tank 10 by the second water pump. Then, the water and fertilizer in the storage tank 10 are sprayed onto the tree crown in the form of mist through the nozzle 7. A multi-frequency, small-volume water and fertilizer spraying method can be used.

[0025] In this application, an annular support ring 11 is connected to the middle of the conveying pipe 4 6, and several reinforcing rods 12 are connected between the support ring 11 and the annular mounting base 4. The connection structure of the support ring 11 and the reinforcing rods 12 can enhance the structural strength of the conveying pipe 4 6, and the structure formed by the conveying pipe 4 6, the support ring 11 and the reinforcing rods 12 constitutes a enclosure device to protect the ancient tree.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
