受褐飞虱破坏的水稻光谱特性研究
Study on Spectral Characteristics of the Damaged Rice by BPHs
摘要
Abstract
[Objective] The linear model for forecasting the occurrence number of BPHs were built using spectral band and red edge, and use the model to forecast the number of BPHs. [ Method ] Using ASD spectrometer which the measured spectral region ranged from 350 ran to 1 050 nm, at resolution of 3 nm to measure spectral characteristics of the healthy rice and the damaged rice by BPHs. Using the spectrum of the rice to analyze the spectral characteristics of the damaged rice by BPHs. And established a significant negative correlation between the number of BPHs and the spectral characteristics of the damaged rice by BPHs. [ Result] The accuracy of the model were 66. 8% - 81. 2% , the model was efficient for forecasting the number of BPHs. [ Conclusion] Hyper spectral can be efficient for forecasting the number of BPHs.关键词
