该研究为了解决这一问题,自主研发了一套高通量根系表型平台(图1),包括根盒系统、自动数据采集、智能灌溉等核心模块,实现大规模、精准、高效的根系生长监测。该平台由根盒、支架、自动导引车(AGV)、电动伸缩遮雨装置等组成,可同时测定1680株幼苗的根系生长动态。根盒采用矩形结构(高60 cm、宽30 cm、厚1.5 cm),前侧、两侧及底部由钢板封闭,背面嵌入透明玻璃,并倾斜45°放置,以利用根系向地性促使根部贴附玻璃生长,实现高质量成像。自动化成像系统搭载Basler-acA5472工业相机,光轴垂直于玻璃面,结合LED光源均匀照明,相机沿轨道移动,在检测到限位传感器后自动捕获图像,每张图像分辨率5472 × 3648像素,单次扫描可拍摄两组根盒。该平台还配备自动滴灌系统确保精准控水,实现不同环境下的根系生长监测和干旱胁迫实验。
