Automated sowing performance monitoring for pneumatic roller-type vegetable plug-tray seeders helps reduce labor and ensure high sowing quality. In this study, a row of optical fiber sensors was utilized, and an optoelectronic measurement system was constructed based on the row-by-row sowing principle of the seeder. Performance of the measurement system was evaluated by sowing ten types of vegetable seeds. The results demonstrated there were no significant differences in measurement accuracy at different sowing speeds. Further, the seed properties did not influence the missed-seeding consistency ratio (CR_ms). The average CR_ms of the developed system was 99.81%. Seed shape was an important factor that influenced the single-seeding (CR_ss) and multiple-seeding (CR_mu) consistency ratios. Seeds with greater than 85% sphericity obtained an average CR_ss and CR_mu of greater than 99%, which demonstrated that the developed measurement system could be applied to vegetable plug-tray sowing.

气动滚筒式蔬菜插秧机播种机的自动播种性能监测有助于减少人工并确保高播种质量。在这项研究中，利用了一排光纤传感器，并根据播种机的逐行播种原理构建了一个光电测量系统。通过播种十种蔬菜种子来评估测量系统的性能。结果表明，在不同播种速度下，测量精度没有显着差异。此外，种子性质不影响种子漏失一致性比（CR _ms）。所开发系统的平均CR _ms为99.81％。种子形状是影响单播（CR _ss）的重要因素。）和多播（CR _mu）一致性比率。球形度大于85％的种子获得的平均CR _ss和CR _mu大于99％，这表明开发的测量系统可用于蔬菜插秧盘播种。
