Description

Technical Field

[0001] This utility model relates to an exogenous substance application device for improving the salt tolerance of bougainvillea, belonging to the field of landscaping. Background Technology

[0002] Bougainvillea requires salt-tolerant exogenous substances in specific growing environments. Salt stress refers to the adverse effects on plants caused by excessively high salt concentrations in soil or irrigation water, such as the accumulation of sodium ions and chloride ions. These effects include water shortage causing wilting, stunted growth, yellowing and shedding of leaves, hindered photosynthesis, abnormal respiration, leaf curling, and deformed new leaves.

[0003] Bougainvillea is a moderately salt-tolerant plant, but different varieties have different salt tolerance levels and may not be able to withstand salt stress. They need the help of exogenous substances. Exogenous substances can help bougainvillea alleviate salt stress by supplementing nutrients, enhancing antioxidant capacity, or regulating physiological metabolism.

[0004] However, current technology lacks the equipment to monitor the degree of soil salinity stress and accurately implement the use of exogenous substances.

[0005] Therefore, this utility model provides an exogenous substance application device that can precisely control the application of exogenous substances and adapt to different salt stress environments, thereby improving the salt tolerance of bougainvillea. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an exogenous substance application device for improving the salt tolerance of bougainvillea.

[0007] This utility model is implemented as follows: An exogenous substance application device for improving the salt tolerance of bougainvillea includes a spraying system for spraying the exogenous substance and a permeameter. The permeameter includes a permeameter cylinder and a permeable plate. The permeable plate is installed at the bottom of the inside of the permeameter cylinder so that when the permeameter cylinder is inserted into the soil, water in the soil can permeate into the permeameter cylinder from the bottom. The permeameter also includes a circuit board, a soil conductivity meter, and a first liquid level sensor. The top of the permeameter tube has a receiving cavity provided by a partition. The receiving cavity is used to receive the circuit board. The soil conductivity meter and the first liquid level sensor are located in the receiving cavity and electrically connected to the circuit board. The free ends of the soil conductivity meter and the first liquid level sensor both extend through the partition to the bottom of the permeameter tube.

[0008] As a further improvement, the spraying system includes a first pipe, several T-pipes and spray heads. One end of the T-pipe is sealed by a second baffle, and this end is detachably and fixedly connected to the top of the permeation cylinder of the permeameter. The other two ends of the T-pipe are respectively connected to the first pipe and the spray heads, so that the liquid in the first pipe flows through the T-pipes and is sprayed out by the spray heads.

[0009] As a further improvement, the tee and the permeation cylinder are threaded together.

[0010] As a further improvement, the permeation tube is made of transparent acrylic or stainless steel.

[0011] As a further improvement, the height of the permeation tube is 10-30cm.

[0012] As a further improvement, the bottom of the permeation tube is conical or frustum-shaped.

[0013] As a further improvement, the spraying system also includes a metering pump, a mixing tank, a clean water tank, and a mother liquor tank. The output end of the metering pump is connected to a first pipeline, and the input end of the metering pump is connected to the mixing tank through a second pipeline. The mixing tank is connected to the clean water tank and the mother liquor tank through a second metering pump.

[0014] As a further improvement, this utility model also includes a PLC controller, which is wirelessly or electrically connected to the metering pump, the second metering pump, and the circuit board.

[0015] The beneficial effects of this utility model are as follows: This utility model integrates a spraying system with a permeameter for monitoring the degree of soil salt stress. A soil conductivity meter is used to detect the salt content of the soil in the area, and a first liquid level sensor detects the moisture content of the soil in the area. This is to avoid the situation where there is no water in the permeameter tube, which would prevent the soil conductivity meter from being used. If no water is detected in the permeameter tube by the first liquid level sensor, the signal is transmitted to the PLC controller to control the spraying system to spray liquid and increase the moisture content of the soil in the area. If the salt content of the soil in the area is high, the spraying system can also spray liquid on the soil in the area until the salt content in the area reaches the standard. This achieves precise control of the application of exogenous substances, resulting in better salt tolerance of bougainvillea planted in the area. Attached Figure Description

[0026] Reference Figures 1-6 As shown, this embodiment provides a specific implementation of an exogenous substance application device for improving the salt tolerance of bougainvillea, including a spraying system for spraying exogenous substances and a permeameter 10. The permeameter 10 includes a permeameter cylinder 101 and a permeable plate 102. The permeable plate 102 is installed at the bottom of the inside of the permeameter cylinder 101 so that when the permeameter cylinder 101 is inserted into the soil, water in the soil can permeate into the bottom of the permeameter cylinder 101. The permeameter 10 also includes a circuit board 103, a soil conductivity meter 104, and a first liquid level sensor 105. The top of the permeameter cylinder 101 is provided with a receiving cavity 111 through a partition 112. The receiving cavity 111 is used to receive the circuit board 103. The soil conductivity meter 104 and the first liquid level sensor 105 are located in the receiving cavity 111 and are electrically connected to the circuit board 103. The free ends of the soil conductivity meter 104 and the first liquid level sensor 105 both extend through the partition 112 to the bottom of the permeameter cylinder 101. The soil conductivity meter 104 indirectly reflects important physicochemical properties of the soil, such as salt content, moisture status, and nutrient level, by detecting the conductivity of the soil solution. The soil conductivity meter models are DEC-2, HI993310, and DUALEM-421. The first liquid level sensor 105 is used to detect the liquid level in the permeameter cylinder 101.

[0027] This utility model also includes a PLC controller 90, which is wirelessly or electrically connected to the metering pump 50, the second metering pump, and the circuit board 103.

[0028] In the above technical solution, the spraying system and the permeameter 10 for monitoring the degree of soil salt stress are integrated. The soil conductivity meter 104 is used to detect the salt content of the soil in the area, and the first liquid level sensor 105 detects the moisture content of the soil in the area. This is to prevent the soil conductivity meter 104 from being unable to operate if there is no water in the permeameter 101. If the first liquid level sensor 105 detects that there is no water in the permeameter 101, the signal is transmitted to the PLC controller 90 to control the spraying system to spray liquid and increase the moisture content of the soil in the area. If the salt content of the soil in the area is high, the spraying system can also spray liquid on the soil in the area until the salt content of the area reaches the standard, so as to achieve precise control of the application of exogenous substances and make the bougainvillea planted in the area more salt-tolerant.

[0029] The specific structure and principle are as follows: The spraying system includes a first pipe 20, several T-pipes 30 and spray heads 40. One end of each T-pipe 30 is sealed by a second partition 301 and is detachably and fixedly connected to the top of the permeation cylinder 101 of the permeameter 10. The other two ends of the T-pipe 30 are respectively connected to the first pipe 20 and the spray heads 40, so that the liquid in the first pipe 20 flows through the T-pipes 30 and is sprayed out from the spray heads 40.

[0030] The spraying system also includes a metering pump 50, a mixing tank 60, a clean water tank 70, and a mother liquor tank 80. The output end of the metering pump 50 is connected to the first pipe 20, and the input end of the metering pump 50 is connected to the mixing tank 60 through a second pipe. The mixing tank 60 is connected to the clean water tank 70 and the mother liquor tank 80 through the second metering pump. One of them, the mother liquor tank 80, stores high-concentration solutions of exogenous substances such as salt tolerance regulator mother liquor, and is usually equipped with a level sensor to monitor the remaining amount in real time. The clean water tank 70 stores clean water for dilution, and is mostly made of corrosion-resistant plastic or stainless steel to avoid water pollution.

[0031] Among them, the metering pump 50 and the second metering pump are both capable of precisely controlling the fluid delivery volume. Specifically, the second metering pump is connected to the mother liquor tank and the clean water tank respectively. By setting the flow rate parameters, such as the hourly delivery volume, the mixing ratio of the two liquids is controlled, and then the liquid flows to the mixing tank 60. The metering pump 50 draws liquid from the mixing tank 60 to the first pipeline 20 by setting the flow rate parameters, and then delivers it to each sprinkler head 40 to spray the bougainvillea in the area.

[0032] Furthermore, both metering pump 50 and the second metering pump are controlled and adjusted by PLC controller 90.

[0033] The three-way pipe 30 and the permeation cylinder 101 are threaded together, and the threaded engagement is tight.

[0034] As one possible specific implementation of this embodiment, the permeation tube 101 is made of transparent acrylic material or stainless steel material, which is convenient for observation and corrosion prevention, thereby improving the practicality of the device.

[0035] As one possible specific implementation of this embodiment, the height of the permeation tube 101 is 10-30cm, which is inserted into the middle of the soil to meet the needs of the test sample. The concentration of the soil surface layer and the middle layer are different. When inserted into the middle of the soil, the permeable plate 102 of the permeation tube 101 blocks the water, allowing water to pass through but blocking soil particles to avoid sample loss.

[0036] As one possible specific implementation of this embodiment, the bottom of the infiltration cylinder 101 is conical or frustum-shaped, and the bottom of the infiltration cylinder 101 has a small contact area with the soil, making it easier to insert into the soil.

[0037] In this embodiment, the permeable plate 102 is a porous ceramic or metal filter screen, which has good anti-corrosion effect and water permeability.

[0038] In this embodiment, the top of the permeation cylinder 101 is also sealed with a cap 106 to prevent water from entering.

[0039] As one possible specific implementation of this embodiment, a plurality of pressure regulators 11 are provided at equal intervals on the first pipeline 20. The pressure regulators stabilize the liquid pressure in the pipeline and avoid affecting the spray volume and concentration stability due to pressure fluctuations.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
