采用高光谱遥感技术袁对受到白叶枯病病害胁迫的水稻冠层进行高光谱检测。通过采集感染不同程度的白叶枯病病害的水稻冠层进行高光谱检测袁并通过移动平均法尧峰值面积归一化法以及一阶微分法进行数据处理袁结果表明院健康水稻与感染不同程度病害的水稻在冠层光谱反射率确实存在差异袁尤其是在感染病害的早期即存在较大的差异袁可以利用水稻冠层的光谱反射率进行水稻病害的早期检测及防治。

Using hyperspectral technology to test canopy of the rice which was damaged by the Bacterial Leaf Blight(BLB).After collecting the rice canopy hyperspectral reflectance of different degree BLB,the data were processed by three methodsthe moving average method,peak normalization method,and 1st derivative.The results showed that existing differences between the health rice and the rice had different degree infected BLB,especially in early stage of the rice infected BLB,it could help to find the rice which had been infected and did something to prevent the rice from getting worse and spreading.
