Description

technical field [0001] The invention relates to a method for measuring plant physiological capacitance at a specific frequency, belonging to the technical field of agricultural engineering and crop information detection, and can quickly find a suitable measurement frequency range, obtain the physiological capacitance of plant leaves at any frequency, and determine the Adaptation to water deficit. Background technique [0002] When using the LCR tester to measure the physiological capacitance of plant leaves, it is usually affected by many factors, such as test voltage, clamping force, plate size, test frequency and other factors. Among them, since the test frequency range given by the instrument is very wide, the test results of different frequencies are very different. Therefore, a method must be found to make the test results of different batches comparable, so that the test results between different plants are comparable. sex. [0003] The study found that the relations...
