玉米高通量自动考种装置设计与试验
考种是玉米育种的重要环节,针对现有考种方法分别进行玉米果穗或玉米籽粒考种参数测量,难以满足玉米商业化育种过程大量样本自动考种需求的现状,该文设计了一种玉米高通量自动考种装置,主要包括玉米果穗考种单元、自动脱粒单元、玉米籽粒考种单元、后处理单元及系统控制单元,可实现玉米果穗考种、自动脱粒、籽粒考种、籽粒提升、籽粒封装、标签打印等全过程的自动化。依据设计方案进行原理样机试制及试验,结果表明:该装置可实现玉米穗质量、果穗长宽、穗行数、行粒数、秃尖区域、籽粒厚度、籽粒长、籽粒宽、穗粒数等考种参数的实时测量,且对果穗长、宽的平均测量精度分别为99.13%,99.25%、对籽粒数量的平均测量精度为99.3...
