Description

Technical Field

[0001] This utility model relates to the technical field of drought stress testing equipment, specifically a drought stress device for testing the function of drought-resistant genes in poplar trees. Background Technology

[0002] Most existing drought stress experiments use pot experiments. While this allows for precise water control, it limits the plant's growing space, fails to accurately reflect field conditions, and cannot be used to test large trees. Therefore, the best approach is to conduct field trials of drought stress, where plants are directly planted in the field to observe their growth. However, when observing the water level inside the pot, users need to bend over to look at the observation port, which can cause neck discomfort due to prolonged bending. Furthermore, the lack of graduations on the glass makes it difficult for users to accurately read the water level, affecting the data collected in the drought stress experiment.

[0003] For example, CN202222592101.5 discloses "A planting device suitable for plant drought stress test". By setting a transparent L-shaped graduated cylinder, it is possible to know the water level in the second flowerpot without having to look down to observe the water level inside the first flowerpot. Since there are scale lines on the surface of the transparent L-shaped graduated cylinder, it is convenient for users to read the water level value.

[0004] In drought stress experiments, poplar trees are placed in test chambers. However, because poplar trees have a certain weight, placing them vertically in the test chamber will cause them to tilt due to their weight. This indirectly affects the water potential and relative water content absorbed by the roots during the later watering process, which is not conducive to the experimental data of the poplar trees.
