Description

Technical Field

[0001] This utility model belongs to the technical field of seed salt tolerance identification equipment, and in particular relates to a device for identifying salt tolerance during the germination period of pumpkin seeds. Background Technology

[0002] Pumpkin, as a widely adaptable crop, occupies an important position in agricultural production. However, the increasingly serious problem of soil salinization has significantly affected the growth and yield of pumpkin. In the entire growth cycle of pumpkin, the seed germination period is the starting stage of its growth and also the period when it is most sensitive to salt stress. Therefore, accurately identifying the salt tolerance of pumpkin seeds during the germination period is of great significance for screening and breeding salt-tolerant pumpkin varieties and improving the planting adaptability of pumpkin in saline soil.

[0003] Currently, most methods for identifying salt tolerance during pumpkin seed germination are relatively traditional and simple. They basically involve manually placing pumpkin seeds in a solution with a certain salt concentration and then observing and identifying the germination. This method can only observe seeds under a single salt concentration and lacks comparative analysis between different salt concentrations. It cannot comprehensively and systematically obtain the salt tolerance performance of seeds under different salt concentration environments.

[0004] To address these issues, we have developed a device for identifying salt tolerance during pumpkin seed germination. Utility Model Content

[0005] The purpose of this invention is to provide a device for identifying salt tolerance during the germination period of pumpkin seeds. Through the combination of a tray, a flat plate, and an adjustment component, it solves the problem that the identification of salt tolerance during the germination period of pumpkin seeds in the prior art usually involves manually placing pumpkin seeds in a solution of a certain salt concentration and then observing and identifying the germination status of the seeds, which results in low identification efficiency and poor identification effect.
