成像光谱技术在农作物信息诊断中的研究进展

Advance of the Imaging Spectral Technique in Diagnosis of the Information of Crop

传统的农作物信息诊断方法存在劳动强度大、诊断时间长、操作技术要求高、受人为主观因素影响大等缺陷,限制了农作物信息诊断的实时性和准确性。成像光谱技术能够通过同时获得农作物的图像以及光谱信息,实现对农作物生长状况、病虫害等信息的快速、无损检测,已在作物信息诊断中得到越来越广泛的应用,为农业的信息化提供了技术支持。文章概述了成像光谱技术的原理,重点介绍了其在农作物种子成分检测、种子品种分类、种子病虫害检测、田间植株长势监测、田间植株病虫害检测中的国内外最新研究进展,分析了成像光谱技术应用于农作物信息诊断的难点,并对其发展方向进行了展望。

Labor intensive,time consuming,high technical requirements in operation and much affected by human factors is the limitation of diagnosing the crop information with conventional method,which could not make diagnosis real-time and rapid.Imaging spectral technique could simultaneously obtain the image and spectral information of crops.It could diagnose the growth and insects information of crop rapidly and non-destructively.In recent years, imaging spectroscopy has been widely used in diagnosis of the information of crop,so it provides technical support for agricultural informatization.In the present study,the principle of imaging spectroscopy was presented.The application progress of imaging spectroscopy technique in crop detection was investigated, including seed component detection,seed variety discrimination,seed disease and insect pest detection,field crop growth monitoring and field crop disease and insects monitoring.Then the paper analyzed difficulty of imaging spectroscopy for crop measurement,and the prospect of this technique was also discussed.
