Characteristics of Hyper-spectral Reflectance of Broomcorn Millet Canopy in Semi-arid Region
摘要
Abstract
Hyperspectral remote sensing can rapidly acquire information of crop canopy parameters. It is an important technology to monitor and manage crop growth in real time. In order to explore characteristics of broomcorn millet canopy spectral,the canopy spectral reflectance were measured under different varieties and planting densities,and the red edge features were also analyzed. The results showed that the canopy spectral under different varieties showed the consistent trend,and the discrepancy in each wave band was different. Under the different density treatments,the spectral reflectance in the biggest density (D3)were slightly bigger than the other treatments in 350-1 000 nm,which were not significant in other wave band. From the flowering stage to late filling stage,the“blue shift”phenomenon occurred at the position of red edge,and the slope of red edge reduced.关键词
