Description

Technical Field

[0001] The present application relates to the field of plant protection technology, and in particular to a device for quickly measuring agronomic traits of tobacco plants. Background Art

[0002] Different tobacco varieties have different characteristics during their growth process. During their growth process, researchers need to measure physical parameters such as the stem-leaf angle and tobacco leaf length of the tobacco plants to determine the maturity of the tobacco leaves and the plant structure, but the existing measurement tools are simple in structure and inconvenient to operate, which seriously affects the measurement work of researchers. Although research has been carried out on the stem-leaf angle measuring device disclosed in CN202122106919.7, the measuring device is only a first arm and a second arm with adjustable angles and hinged at one end, and a protractor is set between the first arm and the second arm to achieve accurate measurement of the stem-leaf angle. However, the device still has the problem of low measurement efficiency.

[0003] Existing measurement tools also have the following disadvantages:

[0004] 1. The existing tobacco plant measuring device has a single measurement function and can only measure the tobacco leaf length, tobacco plant diameter or stem-leaf angle, but cannot measure all the above parameters at the same time;

[0005] 2. The existing tobacco measuring device is inconvenient to operate when measuring the angle. It is necessary to align the measuring ruler vertically with the tobacco stem to obtain a more accurate measurement result. The alignment process is cumbersome, and due to the lack of fixed parts, it is easy to shift after alignment, which causes the measurement personnel to spend more time and energy. In addition, the accuracy of the test results depends entirely on the operator and cannot be effectively guaranteed;

[0006] 3. The existing tobacco plant measuring device cannot closely contact the tobacco plant stem or tobacco leaf when measuring the stem-leaf angle, resulting in inaccurate measurement results;

[0007] 4. The existing tobacco plant measuring device has sharp corners, which may easily cause damage to the tobacco plants or leaves during the measurement process.

[0008] The information disclosed in the background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in the field.
