Description

Technical Field

[0001] This utility model relates to the field of crop measurement technology, specifically a crop phenotypic measurement system. Background Technology

[0002] Crop phenotype refers to the external characteristics and functional traits of crops, including morphology, structure, physiology, and chemistry, exhibited under specific environmental conditions. It is the result of the interaction between genes and the environment, reflecting important traits such as crop growth and development, stress resistance, yield, and quality. Crop phenotype includes not only morphological characteristics such as plant height, leaf shape, and root structure, but also physiological functions such as photosynthetic efficiency, resistance to pests and diseases, and water and nutrient use efficiency. Through the study of crop phenotypes, agricultural scientists can better understand the adaptability and performance of crops under different environmental conditions, thus providing a scientific basis for crop improvement, variety selection, and agricultural production management, and helping to improve crop yield, quality, and adaptability to environmental changes.

[0003] CN217980224U discloses a plant phenotypic measurement device, comprising: a main frame with a detection channel for plants to enter and exit; a detection component disposed on the main frame above the detection channel and configured to measure plant phenotypic information; a vertical transmission component configured to control the vertical movement of the detection component; a translational sliding component disposed on the main frame at the bottom of the detection channel and configured to transport the plant reciprocatingly along a horizontal measurement direction; and a control box disposed on the main frame and configured to control the reciprocating movement of the vertical transmission component, the translational sliding component, and the measurement of the detection component. By controlling the translational sliding component through the control box to adjust the vertical position of the detection component, and controlling the translational sliding component to transport the plant reciprocatingly along the horizontal measurement direction, the detection component measures the phenotypic information of a single plant in the horizontal measurement direction.

[0004] However, when using the aforementioned plant phenotyping device, the detection component is located above the platform, so the plant can only be photographed from above. When the top of the plant is large and covers the bottom, it is inconvenient to detect the phenotyping of the bottom and sides of the plant. Utility Model Content
