Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of seeding equipment, and particularly relates to a breeding laboratory self-adaptive seeding device and a seeding method. BACKGROUND

[0002] In the field of agricultural breeding, seeding is one of the key steps in the experimental process. However, most breeding laboratories still rely on manual operation when seeding, which has many shortcomings. First, manual seeding is low in work efficiency and cannot meet the needs of large-scale experiments, and long-time repetitive labor can easily cause the fatigue of workers. Second, it is difficult to accurately control the spacing between seeds when manually seeding, and the inconsistency of seed spacing will affect the growth environment and competition conditions of seeds, thereby adversely affecting the experimental results. In addition, the depth of seed burial in the soil is also difficult to keep consistent when manually seeding, which may lead to the inconsistency of seed germination rate and growth speed, further affecting the accuracy of the experiment. Due to the above problems, manual seeding often leads to the inconsistency and irreproducibility of experimental data, reducing the accuracy and reliability of the experiment. Therefore, it is of great significance to develop an automatic seeding device that can improve the seeding efficiency, accurately control the seed spacing and seeding depth, for improving the efficiency and quality of breeding experiments.

A sowing method for an adaptive sowing device for a breeding laboratory according to any one of claims 1-6, characterized in that, Includes the following steps: S1: Set the front end of the Y guide rail (8) and the middle of the X guide rail (4) as the reference position, with the reference position located directly below the vision camera (11); S2: Place the breeding tray on the support platform (7), obtain the shape and height of the breeding tray through the vision camera (11), determine the initial sowing position on the breeding tray, and calculate the offset between the initial sowing position and the sowing position; S3: Input the sowing spacing and depth on the control panel of the electric control box, calculate the descent distance, round trip and sowing interval of the sowing component (2) based on the obtained shape and height data of the breeding tray, and calculate the motion type and motion interval of the Y-axis sliding component, X-axis sliding component and rotating component at the same time; S4: Based on the offset, the breeding disc is moved to the sowing position through the Y-axis sliding component and the X-axis sliding component, so that the preset initial sowing position is directly below the sowing nozzle (12); S5: Based on the obtained shape and height data of the breeding tray, the displacement of the breeding tray is controlled by the Y-axis sliding component, the X-axis sliding component and the rotation component, and the quantitative and precise sowing of the breeding tray is completed by the up and down displacement of the sowing component (2) in the Z direction.
