Data for: Data set of Visible-Near Infrared handled and micro- spectrometers - comparison of their accuracy for predicting some sugarcane properties.

Chemical and Nir spectra measurements were made on 60 sugarcane samples from different plant parts (leaves, stem or whole aerial part). Chemical parameters (total sugar content - TS, crude protein content - CP, acid detergent fiber - ADF, in vitro organic matter digestibility - IVOMD were determined. In parallel, reflectance spectra were measured using eight spectrometers. To illustrate, PLS-R results are showed for the total sugar content and crude protein contents.本研究针对取自不同植株部位（叶片、茎秆或全地上部分）的60份甘蔗样本，开展了化学成分与近红外光谱（Near-Infrared, NIR）测定。所测定的化学成分参数涵盖总糖含量（Total Sugar Content, TS）、粗蛋白含量（Crude Protein Content, CP）、酸性洗涤纤维（Acid Detergent Fiber, ADF）以及体外有机物消化率（In Vitro Organic Matter Digestibility, IVOMD）。同步采用8台光谱仪采集了样本的反射光谱数据。为便于示例说明，本文展示了针对总糖含量与粗蛋白含量的偏最小二乘回归（Partial Least Squares Regression, PLS-R）分析结果。
