technical field

The utility model belongs to the technical field of plant experiments, in particular to an experimental device for simulating waterlogging stress of plants.

Background technique

Waterlogging mostly occurs in coastal wetlands, which inhibits plant growth, reduces crop yields, and hinders the development of planting in this area. By simulating plant waterlogging stress through pot experiments, the physiological response mechanism and regulation mechanism of crops to waterlogging can be ascertained, which can serve for the screening and cultivation of waterlogging-tolerant crop varieties. In the prior art, methods for treating plant waterlogging include the oil-sealed dissolved oxygen adjustment method, the double-set pot method, and flooding the ground.
