Prediction of ensiled maize quality traits with near infrared diffuse reflectance spectroscopy (NIDRS)
研究利用近红外漫反射光谱法（NIDRS）测定青贮玉米的体外干物质消化率 (IVDMD)、中性洗涤纤维(NDF)、酸性洗涤纤维 (ADF)、粗蛋白（CP）和粗脂肪（EE）含量的可行性。以普通、高油和超高油玉米全株和秸秆的青贮样为材料，采用光谱的主成分空间技术和偏最小二乘回归法（PLS）。所建立的IVDMD、NDF、ADF、CP和EE的校正模型的交叉验证决定系数(R2cv)分别为0.9133、0.9764、0.9789、0.9254和0.7294，外部验证决定系数(R2val)分别为0.8879、0.9455、0.9635、0.9387和0.7333，各项误差(RMSEE、RMSECV和RMSEP...

This study was conducted to investigate the feasibility of measuring in vitro dry matter digestion (IVDMD), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP) and ether extract (EE) concentrations in ensiled maize by near infrared diffuse reflectance spectroscopy (NIDRS). The ensiled stover and whole plant samples from normal oil maize, high oil maize and super oil maize were used to establish NIDRS calibration models of ensiled maize with the techniques based on the principal component space of spectra and partial least square regression (PLS).
