Description

Technical Field

[0001] The present invention relates to the technical field of agricultural detection equipment, and in particular to an intelligent detection device for the angle of wheat leaves in a field. Background Art

[0002] Wheat plant type is a comprehensive description of the spatial morphology, function and characteristics of the plant's leaves and stems, mainly referring to the angle between the leaves and stems, stem characteristics, leaf shape, size and angle, ear type and ear verticality, etc.; wheat yield is directly affected by plant type, and comprehensive regulation from the aspects of individual genetics, group structure, ecological environment, etc. can enable the crop to achieve a reasonable group photosynthetic situation.

[0003] To achieve high-quality, high-yield and stable wheat production, it is necessary to establish an ideal plant type. Some scholars believe that the ideal plant type is one with fewer tillers per plant, short and upright leaves, and large ears. Studies have shown that in the process of transformation from low-yield to high-yield, the height of wheat plants decreases significantly, resulting in an increase in the width of the flag leaf and the second leaf, a decrease in the aspect ratio, and a change in the angle of the flag leaf from drooping to upright. Some people also believe that upright-ear wheat has a small shading area, which increases the light transmittance of the ear and the lower part of the group, which is beneficial to the photosynthesis of the group. It can be seen that the wheat plant type and leaf angle directly affect the group structure, photosynthetic efficiency and final yield.

[0004] However, the current experimental means of observing wheat plant type mainly rely on manual measurement or taking pictures with mobile phones and then performing image analysis. There are problems such as complex background of single stems, the angle of the natural state of the plant is easily affected by external factors and changes, complex procedures, time-consuming and labor-intensive, etc. Therefore, the present invention proposes an intelligent detection device for the angle of wheat leaves in the field to solve the problems existing in the prior art.
