    • 摘要: 通过对大熊猫采食后峨热竹粗灰分和干物质含量进行观测,探讨峨热竹粗灰分和干物质含量的变异规律,及其受野生大熊猫采食的影响机制.结果表明:相同竹龄条件下,采食样方同一构件的粗灰分含量显著高于对照样方(P<0.05),干物质的含量总体高于对照样方(P>0.05);枝叶粗灰分的含量显著高于竹秆(P<0.05),而干物质的含量总体低于竹秆.随着竹龄的增加,不同竹龄粗灰分的含量大致呈逐年上升的趋势,而干物质的含量总体上呈下降趋势.大熊猫采食对于峨热竹粗灰分和干物质的积累没有明显的影响,粗灰分和干物质不会影响野生大雄猫对峨热竹的可持续利用,有利于大熊猫放归基地栗子坪自然保护区内的大雄猫生存繁衍.

    • 摘要: The experiment aims to establish a near-infrared fast-prediction model which measures the nutrition components of rapeseed straw using near-infrared reflectance spectroscopy (NIRS). 125 rape straw samples were collected from Gansu Province, Qinghai Province and Ningxia Hui Autonomous Region, and then the dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), coarse ash (Ash), neutral detergent insoluble protein(NDIP), acidic detergent insoluble protein (ADIP), acid detergent lignin (ADL), non-protein nitrogen (NPN) and soluble protein (SP) of the samples were determined. 100 rape straw samples were selected as calibration set to build calibration models. Another 25 samples were used as external validation set to evaluate the NIRS prediction model. The results showed that: 1) the contents of DM, CP, NDF, ADF, EE, Ash, NDIP, ADIP, ADL and NPN in rape straw were 93.62%, 5.85%,67.22%, 55.40%, 2.57%, 7.66% and 1.04%, 0.63%, 13.58%, 1.70%, respectively. 2) The coefficient of determination for cross-validation (1-VR) and coefficient of determination for calibration of DM, CP, NDF, EE, Ash, NPN and SP were greater than 0.9 and 0.84, respectively, indicating that these NIRS models could be used in routine analysis. 3)The model parameters of DM, CP, NDF, EE, Ash, NPN and SP were Standard MSC 1,4,4,1, Weighted MSC 2,4,4,1, SNV 2,4,4,1, Standard MSC 1,4,4,1, SNV and Detrend 1,4,4,1, Weighted MSC 1,4,4,1, respectively, whereas the model of other nutritional components is not ideal and needs further improvement. In summary, the availability of nutritional composition correction model for rape straw was verified by internal and external validation.%本研究旨在利用近红外光谱技术(near infrared reflectance spectroscopy, NIRS) 建立油菜(Brassica napus) 秸秆常规成分的近红外快速预测模型.从甘肃省、青海省与宁夏回族自治区共采集125 份油菜秸秆,测定其干物质(dry matter, DM)、粗蛋白(crude protein, CP)、中性洗涤纤维(neutral detergent fiber, NDF)、酸性洗涤纤维(acid detergent fiber, ADF)、粗脂肪(ether extract, EE)、粗灰分(Ash)、中性洗涤不溶蛋白质(neutral detergent insoluble protein, NDIP)、酸性洗涤不溶蛋白质(acid detergent insoluble protein, ADIP)、酸性洗涤木质素(acid detergent lignin, ADL)、非蛋白氮(non-protein nitrogen, NPN) 与可溶性蛋白(soluble protein, SP).选取100 份油菜秸秆样品作为定标集,另外25 份作为验证集来评价NIRS 预测模型.结果显示,1) 油菜秸秆DM、CP、NDF、ADF、EE、Ash、NDIP、ADIP、ADL、NPN 和SP 的含量分别为93.62%、5.85%、67.22%、55.40%、2.57%、7.66%、1.04%、0.63%、13.58%、1.70% 和2.89%.2)DM、CP、NDF、EE、Ash、 NPN 和SP 的交互验证决定系数(1-VR) > 0.9,外部验证决定系数(RQS ≥ 0.84),构建模型可以用于日常分析.3)DM、 CP、NDF、EE、Ash、NPN 和SP 的模型参数分别为Standard MSC 1,4,4,1、Weighted MSC 2,4,4,1、SNV 2,4,4,1、Standard MSC 1,4,4,1、SNV and Detrend 1,4,4,1、Weighted MSC 1,4,4,1,其余营养成分构建模型不太理想,需进一步完善.综上,通过交互验证与外部验证验证了油菜秸秆各营养成分校正模型的可利用性.

    • 摘要: 灰分,是指样品经干燥、碳化,再经过高温灼烧(一般是550℃±25℃或900℃±25℃)即灰化,发生一系列物理化学变化,有机成分挥发后残留的难以挥发的盐类和氧化物的总称。一般情况下,灰分均指总灰分——普遍意义上大家认为灰分代表了食品中无机物的总量,但这个说法并不十分严密,因为在灰化过程中,样品中一部分有机物经过氧化分解后与金属离子反应,以盐的形式保留下来,而样品中的部分无机物可能挥发损失(如siO2等物质会有所变化),因此严格来说,这个灰分并不能真正代表样品中无机物总量,所以它又被冠以另一个称号一一“粗灰分”。
