植物叶片SPAD值经过厚度补偿后可以一定程度的消除叶片厚度差异带来的影响,且更能准确反映植物叶绿素含量的变化趋势。为了满足测量植物叶片厚度及SPAD值两个参数的目的,同时具备操作简单,便携的特点,适合野外实地测量,介绍了集成光学测量系统及测量厚度的电感传感器于一体的新型测头,保证了测量准确度和稳定性。 Plant leaf SPAD value after thickness compensation can be certain to eliminate the impact of leaf thickness differences, and more accurately reflect the changing trend of plant chlorophyll content. In order to meet the purpose of measuring two parameters of plant leaf thickness and SPAD value, it is easy to operate and portable. It is suitable for field measurement. It introduces a new type of probe which integrates optical measurement system and thickness sensor to ensure that Measurement accuracy and stability.
