Description

Technical Field

[0001] This utility model relates to the field of rice disease resistance breeding technology, and more specifically, to a measuring device for rice disease resistance breeding. Background Technology

[0002] The measurement device for rice disease resistance breeding is a rapid, objective, and quantitative assessment of the severity of diseases in rice plants, thereby assisting breeders in screening superior disease-resistant lines. It replaces or assists in artificial disease rating, enabling the measurement and observation of rice disease resistance. By comprehensively utilizing visible light imaging, multispectral / hyperspectral imaging, and lidar technology, it accurately captures the impact of diseases on rice plants from multiple dimensions, including morphology, physiological and biochemical components, and three-dimensional structure.

[0003] Measuring devices for rice disease resistance breeding are used for screening the disease resistance of large-scale hybrid offspring populations, as well as for variety disease resistance identification and quality inspection. For example, rice sheath blight is one of the most common major diseases of rice, generally more severe in early rice than in late rice. In severe cases, it can cause the plants to lodging and die, and is also known as cloud stripe disease. In the process of rice breeding, measuring devices are used to observe whether rice has rice sheath blight.

[0004] For example, in existing rice disease resistance breeding measurement devices, rice sheath blight may occur during the rice breeding process. Therefore, it is necessary to measure whether rice leaves have rice sheath blight. When taking pictures of rice leaves for measurement, it is not convenient for the breeding leaves to be automatically transported and moved into the measurement device for taking pictures. Taking and placing rice leaves is quite troublesome. Moreover, it is not convenient to adjust the shooting distance when taking pictures of rice leaves, which is not conducive to clearly photographing whether rice leaves have rice sheath blight. Therefore, it is necessary to develop a rice disease resistance breeding measurement device that can automatically pick up and place rice leaves and adjust the shooting distance of rice leaves.

The rice breeding measurement mechanism includes a measurement box installed at the top center of the side plate, inlets and outlets on both sides of the bottom of the measurement box, a positioning and placement mechanism installed at the bottom of the measurement box for intercepting and pausing rice breeding leaves, and a shooting mechanism installed above the positioning and placement mechanism for taking images of the surface of the rice breeding leaves.

[0007] In a preferred embodiment, a support plate is fixed between the two side plates and inside the conveyor belt. Rotary rollers are rotatably mounted at both ends of the conveyor belt, and the rotary rollers are rotatably mounted at both ends between the two side plates.
