农作物种子的粒数(单株或单穗粒数)、和粒重是农作物产量的重要构成因素,是作物遗传、育种、栽培研究中的重要考种项目,种子粒重也是种子经营部门衡量种子品质的重要指标。然而,国内历来是采用人工数粒、天平称重、手工记录,从几个重复样本中求计种子的平均粒重。在科研和种子经营、生产过程中,将成千上万个样本采用这种多工序,分段式手工作业,既费工又难确保数据可信。据浙江农业大学种子教研室测定,人工数粒、每数千粒种子平均需10—15分钟,再加上人工操作天平、手记手算, Crop seed grain size (single or per spike grain), and grain weight is an important component of crop yield, crop genetic, breeding, cultivation of important test items, seed weight is also a measure of seed seed business units An important indicator of quality. However, in China, the average seed weight of seeds has been calculated from a few replicate samples by using manual counting, balance weighing and manual recording. In the research and seed management, production process, thousands of samples using this multi-process, segmented manual homework, it is difficult to ensure that the data is credible. According to the Zhejiang Agricultural University, Department of seed determination, the artificial number of tablets, seeds per thousand seeds on average 10-15 minutes, together with the manual balance,
