Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plant nematodes, in particular to a pathogenicity testing device for plant nematodes. Background Art
[0002] Plant nematodes are tiny invertebrates that are widely found in the soil. Many plant nematodes are important plant pathogens, parasitizing various parts of a plant, including roots, stems, and leaves. For example, root-knot nematodes invade plant roots, forming knots there. This impairs the root system's absorption of water and nutrients, leading to stunted plant growth, yellowing and wilting of leaves, and even plant death in severe cases. Research on the pathogenicity of plant nematodes requires appropriate experimental setups to simulate natural environments and accurately observe the effects of nematodes on plants.
[0003] Existing devices also face issues with maintenance and ease of operation. Cleaning the device, replacing plant samples, or adjusting internal components is often cumbersome and time-consuming, significantly reducing efficiency for nematode pathogenicity research, which requires extensive comparative testing. Furthermore, some existing devices lack scientific water management and fail to accurately simulate the water cycle in a natural environment. This can lead to uneven soil moisture, affecting plant root growth and nematode distribution in the soil, and thus interfering with accurate assessments of nematode pathogenicity. Utility Model Content

[0024] In this embodiment, the bevel gear A22 is rotated by turning the handle 20. Since the bevel gear A22 and the bevel gear B23 are engaged and transmitted, the bidirectional screw 21 is driven to rotate. At this time, the sliding block A19 will drive the limit plate 17 to move toward or oppositely, thereby releasing the limit on the placement plate 3, and then the placement plate 3 can be disassembled. When it is necessary to replace the placement plate 3 of different specifications or clean or disinfect it, the operation can be performed quickly and conveniently, and the design of the water basin 9, filter plate 10, water inlet pipe 11, water outlet pipe 12, water sprinkler plate 13 and water pump 14 constitutes a water circulation system, which can maintain the relative stability of the soil moisture in the planting pot 7.

[0026] In this embodiment, by setting a protrusion 25 on the side of the filter plate 10, and setting a limit block 26, a sliding block B27 and a spring 28 in the drain basin 9, when the filter plate 10 needs to be cleaned or replaced, the limit block 26 is first pulled so that the limit block 26 slides out from the inside of the protrusion 25, thereby releasing the limit on the filter plate 10.

When it is necessary to replace the placement plate 3 of different specifications or to clean or disinfect it, the operation can be done quickly and conveniently. The design of the water basin 9, filter plate 10, water inlet pipe 11, water outlet pipe 12, water sprinkling plate 13 and water pump 14 constitutes a water circulation system.

On the other hand, the water pump 14 pumps the water in the water basin 9 to the water sprinkling plate 13 through the connecting pipe 15, so as to achieve uniform watering of the planting pot 7, simulating self The natural precipitation process can keep the soil moisture in the planting pot 7 relatively stable. The flow of water helps the distribution of nematodes in the soil, which is more in line with the natural infection state and is conducive to studying the pathogenicity of nematodes to plants. When the user pulls the limit block 26, the limit block 26 slides out from the inside of the protrusion 25, thereby releasing the limit on the filter plate 10. When the limit block 26 is pulled, the spring 28 will be compressed. When the limit block 26 is released, the spring 28 will recover, thereby pushing the limit block 26 back to the initial position and re-limiting the filter plate 10, thereby making it easy to disassemble the filter plate 10 without the aid of tools, thereby facilitating the maintenance of the internal components of the device and improving the operability and service life of the device.
