Description

Technical Field

[0001] This utility model belongs to the field of soil monitoring technology, specifically relating to a monitoring device for nitrogen cycle in farmland soil. Background Technology

[0002] China is the world's largest producer and consumer of nitrogen fertilizer. To ensure crop yields, nitrogen fertilizer has become one of the most widely used fertilizers in my country's agricultural production. The nitrogen cycle in farmland ecosystems is closely related to the environmental effects of nitrogen. Nitrogen input to farmland is mainly from nitrogen fertilizer, with biological nitrogen fixation and atmospheric deposition also contributing. Monitoring the overall nitrogen cycle in farmland is of great significance for improving fertilizer utilization and protecting the ecological environment.

[0003] In practical research, soil nitrogen detectors are often used to monitor the nitrogen content in the soil. However, the nitrogen cycle is a long-term process, so it is usually necessary to monitor the nitrogen content in the soil over a long period of time. However, when the probe of the current soil nitrogen detector is inserted into the soil, it is not possible to monitor soil layers at multiple depths, which leads to the inability to obtain data on the nitrogen cycle in the soil per unit area. Utility Model Content

[0004] Based on the problems mentioned in the background technology above, this utility model provides a farmland soil nitrogen cycle monitoring device to solve the problem that current detection instruments cannot monitor soil layers at multiple depths after the probe of the soil nitrogen detector is inserted into the soil, thus resulting in the inability to obtain soil nitrogen cycle data in the overall unit area of ​​soil.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A soil nitrogen cycle monitoring device for farmland includes:

[0007] Pipe assembly, wherein one end of the pipe assembly is flat and the other end is stepped;

[0008] Insertion components, wherein multiple insertion components are provided and are respectively assembled on each pipe opening at the stepped end of the pipe assembly;

[0009] The detection components are provided in multiples and are respectively assembled inside each insertion component;

[0010] An assembly component is disposed at the flush end of the pipe assembly;

[0011] A control display is mounted on the assembly component.

[0012] Based on the above technical solution, the present invention has made the following improvements:

[0013] Furthermore, the insertion component includes a pointed insertion tube, which is disposed on the corresponding port at the stepped end of the pipe assembly, and the pointed insertion tube is provided with four through holes.

[0014] Furthermore, the detection component includes a detection body, which is disposed inside the corresponding pointed cannula. The detection body is provided with a sensor group, which includes an oxygen sensor, a carbon dioxide sensor, a pressure sensor, and a temperature sensor, and the oxygen sensor, carbon dioxide sensor, pressure sensor, and temperature sensor are respectively located at the corresponding through-hole openings.

[0015] Furthermore, the assembly component includes an assembly base disposed on the flush end of the pipe assembly, the control display is mounted on the assembly base by screws, and the assembly base is provided with operating handles on both opposite side walls.

[0016] Furthermore, each data port at the bottom of the control display is connected to the corresponding port of the detection body via a data transmission line. The top of the control display is hinged and covered, and a display screen is provided on the top of the control display.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting up a pipe assembly, with one end of the pipe assembly in a stepped shape, and then assembling each insertion component onto the pipe openings at the stepped end of the pipe assembly, the stepped end of the pipe assembly can be inserted into the soil.

[0019] 2. By setting each detection component in the corresponding insertion part on the stepped end of the pipe assembly, after the stepped end of the pipe assembly is inserted into the soil, each detection component can be in the soil layer at different depths to detect data, thereby obtaining data related to the soil nitrogen cycle in the overall unit area of ​​soil.

[0026] like Figures 1-3 As shown, a farmland soil nitrogen cycle monitoring device includes:

[0027] Pipe assembly 1, one end of pipe assembly 1 is flush, assembly components are set on the flush end of pipe assembly 1, assembly components include assembly base 4 set on the flush end of pipe assembly 1, and operation handles 402 are set on both sides of the assembly base 4. The operation handles 402 can facilitate pressing / pulling pipe assembly 1, so that pipe assembly 1 can be easily inserted into the soil or pulled out of the soil.

[0028] Furthermore, the assembly base 4 is also used to assemble the control display 5, which is assembled to the top of the assembly base 4 by screws 401. The control display 5 is powered by a built-in battery. The top of the control display 5 has a hinged cover 502, and the top of the control display 5 has a display screen 503. When the display screen 503 is not needed, the cover 502 can be placed on the top of the control display 5 to cover the display screen 503 and prevent dust and foreign objects from falling on the display screen 503 and the button control area on the top of the control display 5.

[0029] The other end of the pipe assembly 1 is stepped, with multiple insertion components, including pointed insertion tubes 2. The pointed insertion tubes 2 are positioned on the corresponding openings of the stepped end of the pipe assembly 1, facilitating smooth insertion of the stepped end of the pipe assembly 1 into the soil layer. Each pointed insertion tube 2 has four through holes 201. Multiple detection components are also included, each comprising a detection body 3, housed inside the corresponding pointed insertion tube 2. The detection body 3 is equipped with a sensor group 301, which includes an oxygen sensor, a carbon dioxide sensor, a pressure sensor, and a temperature sensor. The oxygen sensor, carbon dioxide sensor, pressure sensor, and temperature sensor are respectively set at the opening of the corresponding through hole 201, which facilitates the contact between the oxygen sensor, carbon dioxide sensor, pressure sensor, and temperature sensor and the soil through the through hole 201; and each data port 501 at the bottom of the control display 5 is connected to the port of the corresponding detection body 3 through the data transmission line 302, so that the corresponding data measured by the oxygen sensor, carbon dioxide sensor, pressure sensor, and temperature sensor can be transmitted to the control display 5 through the data transmission line 302, processed and displayed on the display screen 503;

[0030] In practical use, by pressing 402, the stepped end of the pipe assembly 1 is inserted into the soil layer through the pointed insertion tube 2, and the bottom of the assembly base 4 is pressed against the soil surface, causing each detection unit 3 to be located in the soil layer at different depths. This allows the oxygen sensor, carbon dioxide sensor, pressure sensor, and temperature sensor on each detection unit 3 to detect corresponding data at different soil depths. The oxygen sensor is used to detect changes in the oxygen content in the soil to understand nitrification and denitrification; the carbon dioxide sensor is used to measure the concentration of gaseous CO2 in the soil to help analyze soil respiration rate; the pressure sensor detects changes in soil pressure to help assess the stability and porosity of soil structure; and the temperature sensor is used to monitor changes in soil temperature to help determine the rate and pattern of nitrogen cycling. The corresponding data detected by each detection unit 3 at different soil depths can be transmitted to the control display 5 via the data transmission lines 302 and displayed on the display screen 503, thereby obtaining data related to soil nitrogen cycling in the overall unit area of ​​soil.
