AI Technical Summary

Technical Problem

Existing plant nematode pathogenicity test equipment has problems with cleaning and ease of operation, and water management is not scientific enough, affecting test efficiency and accuracy.

Method used

A device was designed that includes components such as a bracket, a constant temperature box, a placement plate, a planting pot, a drainage basin, a filter plate, and a water pump. The placement plate can be quickly disassembled through a bevel gear and a bidirectional screw system, and the soil moisture is kept stable through a water circulation system to simulate the natural environment.

Benefits of technology

The device can be quickly cleaned and parts replaced, which improves the convenience of operation and test efficiency. At the same time, it simulates the water cycle in the natural environment and improves the accuracy of nematode pathogenicity research.

Abstract

The utility model provides a pathogenicity test device for plant nematodes, which relates to the technical field of plant nematodes and comprises a support, a constant-temperature box and a placing plate, and a sealing door is arranged on the side face of the constant-temperature box. A bevel gear A rotates by rotating a rotating handle, the bevel gear A and a bevel gear B are in meshing transmission, so that a bidirectional lead screw is driven to rotate, a sliding block A can drive limiting plates to move in the same direction or in the opposite directions, limiting of a containing plate is relieved, and then the containing plate can be detached; when placing plates of different specifications need to be replaced or cleaned and disinfected, operation can be rapidly and conveniently carried out, a water falling basin, a filter plate, a water inlet pipe, a water outlet pipe, a water sprinkling plate and a water pump are designed to form a water circulation system, then the soil humidity in the planting basin can be kept relatively stable, water flowing is beneficial to distribution of nematodes in soil, and the nematodes are prevented from being damaged. The natural infection state is better met, and the pathogenicity of the nematodes to plants can be researched easily.
