Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a test device for drought resistance of corn seeds. Background Technology

[0002] Drought resistance of maize seeds refers to their adaptability and resistance to drought. Experiments on drought resistance of maize seeds can explore the effects of drought stress on maize seeds and analyze the impact of different drought levels on maize growth and development, thus providing a theoretical basis for drought-resistant maize breeding.

[0003] In drought tolerance experiments, corn seeds are typically divided into a control group and different drought-prone groups, and planted in separate pots. Different groups receive varying levels of moisture. The germination and survival rates are observed to determine the drought tolerance of the corn seeds. During the experiment, water is usually poured directly into the pots, allowing it to seep into the soil from top to bottom. This method results in more water remaining on the surface and less in the lower layers, and the water distribution varies significantly at different locations within the same height, thus reducing the effectiveness of watering and lowering the accuracy of the experiment.

[0004] Therefore, an experimental device for drought resistance testing of maize seeds is proposed. Utility Model Content
