Rice spectrum features at green, red and near infrared regions were studied by measuring and analysing rice canopy reflectance and differential spectrums with 4 levels of rice leaf blast.
本文通过对4个感染不同等级稻叶瘟的水稻冠层反射光谱进行测试，并对光谱反射曲线进行微分分析，研究了绿光区、红光区和近红外区反射光谱的变异特征。
Besides, effects of rice leaf blast on spectrum reflectance of rice was studied simply.
此外还初步研究了稻叶瘟对水稻冠层光谱特性的影响。
