The fourth agricultural revolution is leading us into a time of using data science as a tool to implement precision viticulture. Infrared spectroscopy provides the means for rapid and large-scale data collection to achieve this goal. The non-invasive applications of infrared spectroscopy in grapevines are still in its infancy, but recent studies have reported its feasibility. This review examines near infrared and mid infrared spectroscopy for the qualitative and quantitative investigation of intact grapevine organs. Qualitative applications, with the focus on using spectral data for categorization purposes, is discussed. The quantitative applications discussed in this review focuses on the methods associated with carbohydrates, nitrogen, and amino acids, using both invasive and non-invasive means of sample measurement. Few studies have investigated the use of infrared spectroscopy for the direct measurement of intact, fresh, and unfrozen grapevine organs such as berries or leaves, and these studies are examined in depth. The chemometric procedures associated with qualitative and quantitative infrared techniques are discussed, followed by the critical evaluation of the future prospects that could be expected in the field.
第四次农业革命正引领我们进入一个将数据科学作为实施精准葡萄栽培工具的时代。红外光谱法为实现这一目标提供了快速大规模数据收集的手段。红外光谱法在葡萄藤中的非侵入性应用仍处于起步阶段，但最近的研究已报道了其可行性。本综述探讨了近红外和中红外光谱法在完整葡萄藤器官定性和定量研究中的应用。讨论了定性应用，重点是利用光谱数据进行分类。本综述中讨论的定量应用侧重于与碳水化合物、氮和氨基酸相关的方法，采用侵入性和非侵入性样本测量手段。很少有研究调查红外光谱法用于直接测量完整、新鲜且未冷冻的葡萄藤器官（如浆果或叶片），本文将对这些研究进行深入探讨。讨论了与定性和定量红外技术相关的化学计量学程序，随后对该领域未来的预期前景进行了批判性评估。
