| 摘 要： | 试验共采集我国北方不同区域、不同生育期、不同干燥方式的羊草干草150份,利用近红外漫反射光谱(NIRS)技术,采用偏最小二乘回归算法(PLS),在国内首次建立了适配范围广的羊草干草的粗蛋白(CP)、中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)的校正模型,并对模型的预测能力进行了验证.结果表明,所建模型的预测结果与常规...

| Abstract: | One hundred fifty Leymus chinensis samples with different growth stage,areas,and preparing method(oven-drying and shading natural dry),were selected to study the potential of determination of crude protein(CP),neutral detergent fiber(NDF)and acid detergent fiber(ADF)in the present research.The quality parameters of Leymus chinensis were firstly predicted using the near infrared reflectance spectroscopy in China.The three models were validated by cross-validation and external-validation.The results indicated... |
