PlantPen叶夹式PRI&NDVI测量仪

PlantPen测量仪是一种快速测量植物反射光谱指数的野外便携式仪器。PlantPen的两种标准版配置分别测量NDVI和PRI这两种应用最为广泛的植被指数。用户也可以定制其他参数。

PlantPen PRI 210:PRI (Photochemical Reflectance Index) 光化学反射指数是通过计算植物叶片对531nm和570nm两个波长光反射而得到的参数。该参数对类胡萝卜素极为敏感,反应植物的光合作用中的光能利用效率和CO2同化速率,并可作为植物水胁迫的可靠指数。因此广泛用于植物产量和胁迫研究。

PlantPen NDVI 310:NDVI (Normalized Difference Vegetation Index)归一化植被指数是通过计算植物叶片对红光和近红外两个波长光反射而得到的参数,是反映植物叶绿素含量的一个重要参数。叶绿素会强烈吸收红光用于光合作用,而叶片细胞结构会强烈反射近红外光。因此,NDVI与光合能力直接相关,从而反映植物冠层的能量吸收状况。
