摘要：用发光二极管作为光源，在短波近红外区选择6个波长的滤光片作为分光器件，研制了单籽粒玉米油分无损测定仪。该仪器各项技术指标均达到设计要求，结构简单、性能稳定;测定单籽粒玉米油分的相关系数为0.968 8，标准差为0.72，平均相对误差为0.062。完全符合高油玉米育种工作的需要。

Abstract：NIR spectrometer for non-destruction measurement of oil contents in an integrated kernel of corn was manufactured. Using LED (light emitting diode) as the light source and six filters as the monochromator, the specifications of the instrument are compared with those of the commercial instruments. The regression coefficient, the standard error, and the relative error of measuring oil contents in an integrated kernel of corn are 0.968 8, 0.72 and 0.062 respectively. The results meet the demand of high-oil corn breeding.
