高光谱技术在作物冠层生理参数检测中的研究进展OA

Hyperspectral technology,as an efficient,non-destructive,and rapid detection tool,has been widely used in crop growth assessment,disaster monitoring,and agricultural production management.Crop physiological parameters are core biochemical indicators reflecting crop growth and nutritional status,which are co-regulated by genotype and environmental factors.Retrieving crop physiological parameters under different environmental conditions and growth stages via hyperspectral technology can provide scientific support for irrigation and fertilization decision-making,which further assists crops in resisting adverse environmental stresses and guarantees crop quality and yield.This paper systematically reviews the basic principles of hyperspectral technology,introduces key research methods for data processing,and focuses on the research progress of hyperspectral technology applied to the detection of crop canopy physiological parameters.It also analyzes the main existing challenges of this technology and prospects its future development directions,aiming to provide theoretical references for future research on detecting crop canopy physiological parameters with hyperspectral technology.
