[0002] Salt stress can cause many adverse effects on plants, such as hindering the synthesis of crop proteins, causing crops to produce toxic substances, affecting crop photosynthesis and respiration, and directly affecting cell membrane lipids and membrane proteins, thereby affecting the normal physiological function of the membrane. Specifically, salt stress can cause salt ion poisoning and nutrient imbalance in plants, leading to physiological and metabolic disorders, growth inhibition, reduced yield and quality, and even death in severe cases.

[0003] In the prior art, plant salt stress tests are mainly soil salt stress tests, which are carried out by applying salt solution, water, and nutrient solution to the soil, stirring them thoroughly and then using them to cultivate plants. Among them, pot tests are the smallest test interval for soil salt stress tests. However, in actual operation, it is relatively difficult to accurately control the consistency of the soil environment in different potted containers. Insufficient watering will lead to uneven distribution of the salt solution, while excessive watering will cause the salt to be lost from the container with the water, thereby affecting the accuracy of the experimental results.
