Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of agricultural planting, more specifically, to a quantitative water supply device for pepper drought resistance experiment. BACKGROUND

[0002] In agricultural scientific research, the study and evaluation of crop drought resistance have always been important topics. As a widely planted crop, the performance of pepper drought resistance is directly related to yield and quality, and thus affects the economic benefits of agricultural production. In order to further study the drought resistance mechanism of pepper and optimize irrigation strategies, scientists have designed various experimental devices to simulate drought environments and accurately control water supply to evaluate the growth and physiological response of pepper under different water conditions.

[0003] Traditional pepper drought resistance experiments usually rely on simulation of natural environment, such as placing pepper plants in a greenhouse or open-air environment, and simulating drought conditions by reducing irrigation amount. However, this method has many shortcomings. First, uncontrollable factors such as water evaporation and rainfall in the natural environment will interfere with the experimental results, making it difficult to accurately reflect the true drought resistance performance of pepper. Second, the traditional method is difficult to accurately control the amount and time of water supply, and cannot meet the demand for accurate control of variables in scientific experiments. In addition, for large-scale experiments, the traditional method has high labor and time cost, limiting the scale and depth of the experiment.

[0004] In order to overcome these challenges, researchers have begun to explore the use of quantitative water supply devices to simulate drought environments and accurately control the water supply of pepper plants. Quantitative water supply devices not only provide stable and controllable water conditions, but also can simulate different degrees of drought stress by adjusting irrigation amount and frequency, thus more accurately evaluating the drought resistance performance of pepper.

[0005] However, existing quantitative water supply devices still have some shortcomings in design and function. Some devices can accurately control irrigation amount, but lack flexibility and cannot adapt to the needs of different experimental areas. For example, some fixed water supply devices are difficult to adjust the irrigation range in the experiment, resulting in experimental results may be affected by uneven irrigation. In addition, some devices are relatively complex in structure, with high operation and maintenance costs, which is not conducive to long-term experiments. SUMMARY
