遥感技术在作物氮素营养诊断中的应用现状分析

Analysis of the Current Application of Remote Sensing Technology in Crop Nitrogen Nutrition Diagnosis

根据遥感技术在作物氮素营养诊断应用中的发展脉络,阐述可见光遥感、卫星遥感和光谱遥感在作物氮素营养诊断方面的理论进展、发展现状和应用前景。就目前研究可以看出,利用遥感技术获取的作物冠层特征参数与作物氮素营养指标之间具有较好的相关性,但作物图像获取、分析处理及特征参数优化等技术方法须要更深入地研究,探寻更简便、精准的方法。

This paper outlines the development,current status,and future prospects of visible light remote sensing,satellite remote sensing,and spectral remote sensing in the diagnosis of crop nitrogen nutrition,following the developmental process of remote sensing applications in this field.Current research indicates that there is a good correlation between crop canopy characteristic parameters obtained by remote sensing technology and crop nitrogen nutrition indicators.However,the acquisition of crop images,analysis and processing,and optimization of characteristic parameters require more in-depth study to find simpler and more accurate methods.
