在评估甘蔗成熟度和确定收获时间表时，农场的甘蔗质量对农民和磨坊主来说都是重要的信息。研究了利用便携式近红外(NIR)仪对甘蔗秸秆含糖量进行无损检测的方法。一种商业上可用的便携式近红外仪被改装成用于透射式模式，并用于定量甘蔗秸秆中的POL水平。利用偏最小二乘回归分析建立了从果汁和甘蔗样品光谱(600-1100 nm)预测POL值的校正模型。结果对果汁和甘蔗样品的预测均方根误差分别为1.0%和1.1%POL。根据这项研究的结果，所开发的测量方法似乎对监测甘蔗质量和制定收获计划是有用的。
Cane quality at the farm is important information for both farmers and millers when evaluating cane maturity and determining harvest schedules. We investigated the non-destructive measurement of the sugar content of cane stalks using a portable near infrared (NIR) instrument. A commercially available portable NIR instrument was modified for use in transmittance mode and employed to quantify Pol levels in cane stalks. Calibration models using a partial least squares regression analysis were developed for predicting Pol values from the juice and the cane sample spectra (600–1100 nm). Results of these calibrations, root mean square error of prediction for juice and cane samples, were 1.0% and 1.1% Pol, respectively. Based on the results of this study, the developed measurement method appears to be useful for monitoring cane quality and the planning of harvest schedules.
